Overview
We are a United States domiciled minerals exploration company with a focus on developing mines from mineral deposits principally located in the United States. We seek to support American supply chain independence by finding and delivering the critical metals necessary for electrification of the economy, with a focus on copper. We believe the United States is significantly under explored and has the potential to yield major new discoveries of these metals.
We are committed to the sustainable development of our projects by embedding Environmental, Social and Governance (“ESG”) criteria in our decision-making framework from the earliest stages of project exploration and development. We continue to build upon our team’s strong ESG track record for leveraging best practices to establish Ivanhoe Electric as a leader in the mining sector. Key considerations that will influence our decision making include, but are not limited to, using clean and renewable energy in our future mining operations, following best practices to meet health, safety and environmental standards, optimizing our water resources, protecting local cultural heritage and biodiversity, minimizing our environmental footprint, as well as ensuring workforce diversity and hiring from local communities. Most importantly, the minerals that are the focus of our exploration and development efforts play a critical role by supporting electrification and enabling the clean energy transition.
Our United States Mineral Projects
Our two material mineral projects are the Santa Cruz Project in Arizona and the Tintic Project in Utah.
Santa Cruz Project
The Santa Cruz Project is a copper exploration project situated in a prolific mining region that hosts some of the largest copper mines in the United States. The Project encompasses 5,975 acres on private land and includes associated water rights. The project location provides excellent infrastructure, including access to rail, interstate highways, and electric transmission lines.
The Initial Assessment for the Santa Cruz Project, completed in September 2023, focuses on a small surface footprint, underground copper mine with an average of 5.5 million tonnes mined annually, exclusively from the high-grade exotic, oxide and enriched domains of the Santa Cruz and East Ridge Deposits. The Initial Assessment estimates life of mine (“LOM”) copper production of 1.6 million tonnes over a 20-year mine life, with projected cash costs of $1.36 per pound of copper produced.
We are advancing environmental, technical, and economic studies for an underground high-grade copper mining operation with a focus on minimizing the surface footprint of the mine while at the same time incorporating leading technologies to improve efficiencies and costs. We are designing a technologically advanced mine that we expect to result in low carbon dioxide emissions per pound of copper produced and be a leading example of responsibly produced domestic copper.
Tintic Project
Tintic is an exploration project located 95 kilometres (“km”) south of Salt Lake City in a historically significant silver producing district that also produced significant amounts of copper and gold. We believe the Tintic district has the potential to host a world-class copper-gold porphyry deposit. We own a majority of the surface land and mineral rights constituting the Tintic Project and we have option agreements in place to own the remaining surface land and mineral rights at Tintic.
Drilling in 2023 has advanced our understanding of the geology of this complex area and is guiding our ongoing exploration in 2024.
Our other mineral projects in the United States include the Hog Heaven Copper-Silver-Gold Project (“Hog Heaven”), located in Montana, where we have been actively drilling since June 2023. We also hold a portfolio of exploration projects throughout the United States, including projects in North Carolina, Nevada, and Oregon.
For purposes of Subpart 1300 of Regulation S-K (“S-K 1300”), we are defined as an exploration stage issuer because our two material properties, Santa Cruz and Tintic, are at the exploration stage and do not have any declared Mineral Reserves. Our other United States mineral properties are also in the exploration stage.

Ma’aden Ivanhoe Electric Exploration and Development Limited Company
In 2023, we established an exploration joint venture with the Saudi Arabian Mining Company (“Ma’aden”) (“Joint Venture”), The Joint Venture is owned 50/50 by Ivanhoe Electric and Ma’aden and has an initial term of five years, which may be extended up to 10 years upon mutual agreement of the parties. The Joint Venture is operating through the newly established limited liability company established under Saudi Arabian law (“Saudi JVCo”). Ma’aden has made available approximately 48,500 km 2 of land under an exploration license (or license application) within Saudi Arabia for exploration by the Joint Venture. We contributed $66.4 million of the proceeds from the sale of our common shares to Ma’aden to fund Saudi JVCo and the Joint Venture, and provide Saudi JVCo with a royalty-free license to use Typhoon™ within Saudi Arabia for the purpose of mineral exploration. The license will remain exclusive to the Joint Venture in Saudi Arabia and effective during the term of the Joint Venture. Saudi JVCo has purchased three new generation Typhoon™ units from the Company’s former parent, I-Pulse, for an aggregate contract price not to exceed $13 million. The first new machine was delivered in the first quarter of 2024. The Joint Venture has also entered into a services agreement with Computational Geosciences Inc. (“CGI”), our 94% owned subsidiary, pursuant to which CGI is responsible for the supply of the services for the analysis of data and processing of the full spectrum of geophysical datasets produced by the Typhoon™ systems.
The Joint Venture is governed by a board of directors and technical committee comprised of an equal number of representatives from each company. The technical committee supervises the exploration activities of the Joint Venture including an initial “land identification stage” where the land Ma’aden has made available will be reviewed and reduced to the most prospective areas for Typhoon deployment. This stage will be followed by generative exploration and drilling stages aimed at identifying mineral resources of an economically viable scale. We are the operator during the exploration phase. Ma’aden will assume operatorship if an economically viable deposit is found and is designated by the Joint Venture for further development. We will also provide training and development to an agreed number of employees of the Joint Venture, on mineral exploration, geology, and the operation of the Typhoon™ units. The Joint Venture is not terminable, other than upon the occurrence of an event of default, by either party until the end of the exploration phase.

Other International Mineral Projects
Our other mineral projects outside of the United States include the Alacran Project in Colombia, the Ivory Coast Project in Ivory Coast, and the Pinaya Project in Peru.
The Alacran Project (also known as the San Matias Project) is owned by our publicly-traded subsidiary Cordoba Minerals Corp. (“Cordoba”). At December 31, 2023, we owned 62.8% of Cordoba’s issued and outstanding shares. The Alacran Project is being developed jointly between Cordoba and JCHX Mining Management Co., Ltd. (“JCHX”).
Alacran is located in the Municipality of Puerto Libertador, Department of Córdoba, Colombia, and is approximately 200 km north of the city of Medellín. The Alacran Project hosts the El Alacrán, Costa Azul, Montiel East, and Montiel West deposits across various mining titles.
A new Feasibility Study was announced on December 18, 2023, “NI 43-101 Technical Report, Feasibility Study, Alacran Project, in Colombia.” Initial capital cost is estimated to be approximately $420.4 million for the construction of a conventional truck-shovel open pit mine. The Project is anticipated to hold an after-tax Net Present Value (“NPV”) of $360 million with an Internal Rate of Return (“IRR”) of 23.8% and a payback period of 3 years. The Project’s mine life is projected to be 14.0 years in addition to the estimated two years of construction and pre-production mining, during which, freshly mined ore will be stockpiled alongside historical tailings. The estimated LOM cash costs for copper, net of by-product credits, is $1.35/lb with by-product credits at $1.31/lb, and a total estimated LOM cash cost at $2.66/lb (cash costs excludes sustaining capital).
The Ivory Coast Nickel-Copper Project, in Ivory Coast is focused on the Samapleu-Grata deposits and is operated through a joint venture, the Samapleu Nickel Corporation Inc., with our partner, Sama Resources. At December 31, 2023, we owned 30% of the joint venture with the option to earn up to a 60% interest.
A new report titled “NI 43-101 Technical Report, Mineral Resource Estimate for the Samapleu and Grata Deposits Project” with an effective date of June 27, 2023 was released August 14, 2023. The Project now includes the Grata deposit nearly doubling the mineral resources compared with the 2020 preliminary economic assessment.
The Pinaya Gold-Copper Project, which is wholly-owned by our subsidiary Kaizen, covers approximately 101 km 2 of granted title, plus an additional 28 km 2 under application and includes more than 10 km of underexplored strike length in southeastern Peru. The Project is an intermediate stage exploration project and includes a NI 43-101 Mineral Resource Estimate titled Pinaya Gold-Copper Project, Caylloma and Lampa Provinces, Peru, NI 43-101 Technical Report with an effective date of April 26, 2016. On February 6, 2024, we completed an arrangement pursuant to which we acquired all of the remaining issued and outstanding common shares of Kaizen.
Typhoon and Computational Geosciences
In addition to our portfolio of mineral projects, we own, through a wholly-owned subsidiary, patents to a proprietary exploration technology known as Typhoon™. We also own a 94% controlling interest in a data inversion business, Computational Geosciences Inc. (“CGI”). CGI was founded in 2010 to commercialize innovative technology developed at the University of British Columbia, Canada to improve and enhance mineral exploration.
The Typhoon™ technology allows us to cost effectively and efficiently generate geophysical images of large-scale mineral deposits to depths of one and a half kilometers or more. CGI software technology consists of sophisticated codes to process geophysical data and build three-dimensional (“3D”) subsurface images that could indicate the presence of various sulfide metals and minerals.
Typhoon™ can and has been used successfully to accelerate and de-risk the exploration process enabling a higher frequency of resource discovery and lowering total exploration costs. Typhoon™ has proven to be an important exploration tool during its deployment at Santa Cruz and Tintic. In July 2022, we completed a 26.5 km 2 (6,500-acre) Typhoon™ 3D induced polarization and resistivity geophysical survey at Santa Cruz which identified multiple large-scale anomalies. The Texaco Ridge Exploration Area was identified in a Typhoon™ survey in September 2022. Ivanhoe Electric drilled 10 holes totaling 8,606 meters (“m”) with a single rig at Texaco Ridge during the first half of 2023. The intention of this drilling was to step out into areas beyond the drilled Texaco Deposit that showed high mineralization potential based on Typhoon™ survey results. Hole SCC-122 at Texaco Ridge intersected broad primary sulfides with an intercept of 327 m @ 0.81% total copper (from 564 m), using a 0.39% total copper cut-off. This intercept includes several zones at the same 0.8% total copper cut-off grade as the nearby Texaco mineral resource. Typhoon™ has also been utilized at many of our other projects. Current and historical deployment of Typhoon™ by us, High Power Exploration Inc. (“HPX”) and third-party clients is shown on the map below.

Quality Assurance/Quality Control
Throughout all of our mineral exploration properties, quality assurance and quality control (“QA/QC”) measures are in place to ensure the reliability and trustworthiness of our exploration data. These measures include written standard operating procedures and independent verifications of aspects such as drilling, surveying, sampling, assaying, data management, and database integrity. Appropriate documentation of QC measures and regular analysis of QC data is essential as a safeguard for project data and form the basis for the QA program implemented during exploration.
Analytical QC measures involve internal and external laboratory procedures implemented to monitor the precision and accuracy of the sample preparation and assay data. These measures are also important to identify potential sample sequencing errors and to monitor for contamination of samples.
We submit a blank, standard, or duplicate sample on every seventh sample. Sampling and analytical QA/QC protocols typically involve taking duplicate samples and inserting QC samples (certified reference material (CRM) and blanks) to monitor the assay results' reliability throughout the drill program.
Samples are securely shipped to reputable analytical laboratories with global quality management systems that meets all requirements of the international standards ISO/IEC 17025:2017 and ISO 9001:2015. The independent labs that we use have robust internal QA/QC program to monitor and ensure quality of assay and other analytical results.

Location, Infrastructure, and Access. Our exploration stage Santa Cruz Project is located in Pinal County, Arizona, 11km to the west of Casa Grande and approximately a one-hour drive, on paved roads, south of Phoenix. The Santa Cruz Project encompasses approximately 78.25 km 2 of land. Santa Cruz was discovered in the 1970s but was undeveloped due to market conditions as well as fragmented title and ownership. The Santa Cruz Project centroid is approximately -111.88212, 32.89319 (WGS84) in Township 6 S, Range 4E, Section 13, Quarter C.
Map: Location of the Santa Cruz Project within the state of Arizona.
Title. The Santa Cruz exploration area covers 75.66 km 2 , including 25.79 km 2 of private land, 2.6 km 2 of Stockraising Homestead Act (“SRHA”) lands, 238 unpatented claims, or 19.32 km 2 of U.S. Bureau of Land Management (“BLM”) land, and 16 mineral exploration permits, or 27.95 km 2 , with the Arizona State Land Department (“ASLD”).
In May 2023, we acquired 5,975 acres of land constituting the surface rights and associated water rights for the Santa Cruz Project in Casa Grande, Arizona, pursuant to the terms of the Purchase and Sale Agreement (“PSA”) with seller Wolff-Harvard Ventures LLC (“Legends Property Group”). At closing, we paid a total of $34.3 million to the seller, which included $5.1 million of previously paid deposits. We also issued a secured promissory note to the seller in the principal amount of approximately $82.6 million over a period of 4.5 years. The promissory note includes an annual interest rate of prime plus 1%. As at December 31, 2023, $48.3 million of principal is remaining to be paid on the promissory note.
In February 2022, Ivanhoe Electric acquired the surface title to 20 acres in the southeast area of the Santa Cruz Project known as Skull Valley. And in May 2022, we acquired the surface title to 100.33 acres in the northeast area of the Project known as CG100. At closing for CG100 we paid $300,000. On the first anniversary of the closing date we paid $300,000. At the second anniversary of the closing date, we will pay $300,000. And on the third anniversary of the closing date, we will pay the final installment of $600,000 to release the deed from escrow.

In 2021 we executed an agreement with Central Arizona Resources (“CAR”) for the right to acquire 100% of CAR’s option over the DR Horton Energy (“DRHE”) mineral title and CAR’s Surface Use Agreement (“SUA”) with Legends Property Group. The agreement with DRHE provides that we (by way of assignment from CAR) have the right, but not the obligation, to acquire 100% of the mineral title in the fee simple mineral estate, 39 Federal unpatented mining claims, and three small, approximately 10 acre surface parcels, by paying $27,870,500 in cash or in shares of our common stock at the election of the owner by August 16, 2024. As of December 31, 2023, we had made payments totaling $17,870,500 under the option. These mineral rights are expected to be formally acquired upon the completion of scheduled payments by Ivanhoe Electric to the current mineral title holder in August of 2024. We now hold, through our wholly-owned subsidiary Mesa Cobre Holding Corp., the option to acquire all the mineral titles contiguous with the acquired surface lands for a unified land and mineral package encompassing the entire Santa Cruz Project.
The mineral rights to Skull Valley were acquired in February 2022 along with the surface title. The mineral rights to CG100 were acquired in May 2022 along with the surface title.
In November 2023, Ivanhoe Electric acquired 16 mineral exploration permits with ASLD, adding an additional 27.95 km 2 of mineral control to the project. These permits are granted for 5 year terms provided annual renewals, renewal applications, and work commitment documentation or in-lieu fees are submitted. At the end of the 5-year term, Ivanhoe Electric can submit for a new mineral exploration permit and be “first in line” to receive another 5-year mineral exploration permit term. These permits grant us the exclusive right to explore for minerals during the permit term. Revenue generated by ASLD for these permits is used to support several public entities, including K-12 public education and State universities.
To retain an unpatented claim on federal land in the USA, a $165 maintenance fee per claim is due annually by September 1st. Based on the current landholding this would amount to $39,720 in annual payments for claim retention.
Royalty interests on the Santa Cruz Project include royalties in favor of ASARCO Santa Cruz, Inc. and Freeport Copper Company of a combined 5% NSR derived from DRHE portions of the project area and in favor of Simmons Devcor Company of a 10% NSR on specific parcels (capped to $7 million with consumer price index calculation). In addition, six other NSR royalties in favor of several individuals encumber specified parcels of the project area with NSR royalty rates of 2%, 1%, 0.5%, 0.075%, 0.015% and 0.0125%. No royalty encumbers the entire known mineral resources at the Santa Cruz Project, other than the ASARCO Santa Cruz, Inc. and Freeport Copper Company royalty. The Simmons Devcor Company royalty and the several individual royalties aggregating to 2.09% encumber specified parcels of the project. NSR royalties are only payable upon production and sale of product. There are no advance royalties.

History. The first discovery of copper mineralization in the area occurred in February 1961 by geologists from the American Smelting and Refining Company (“ASARCO”). They proceeded with preliminary geophysical surveys that same year, including IP, resistivity, seismic reflection, and magnetics. Upon positive results from the geophysical surveys, a small drill program of six holes was funded, with the last hole being the first to intersect the significant mineralization that became known as the ‘West Orebody’ and, in time, the Sacaton open pit mine which lies approximately 8 km to the northeast of the center of the Santa Cruz Project.
ASARCO expanded exploration efforts across the Casa Grande Valley and in 1964 the first hole was drilled on the Santa Cruz Project. By May 1965, seventeen drill holes were completed without similar success, and ASARCO reduced its land position. Subsequent reviews in 1970-1971 deemed the Santa Cruz Project worth renewed exploration activity. Following the initiation of the Santa Cruz Joint Venture (“SCJV”) between ASARCO Santa Cruz, Inc. and Freeport McMoRan Copper & Gold Inc. in 1974, additional ground was acquired around the Santa Cruz North deposit. By this time, various joint ventures, as noted below, had staked considerable ground over and around what would eventually be the Casa Grande West (now Santa Cruz) deposit.
In 1973, David Lowell put together an exploration program called the Covered Area Project (“CAP”) that was funded first by Newmont Mining, then, in succession, by a joint venture between Newmont and Hanna Mining, then Hanna with Getty Oil Corp. and Quintana Corp.; though both Quintana and Newmont would pull out of the project before any discoveries were made. By 1974 over 120 holes were drilled at 20 projects across Southwestern Arizona, with a focus on the Santa Cruz system. Drilling under the CAP program continued through to 1977, at which point Hanna Mining took over as operator under a joint venture with operation funding from Getty Oil Corp. Between 1977 and 1982, Hanna-Getty advanced a tight spaced drill program that delineated an estimated 500 Mt of 1% Cu at Casa Grande West, and countless exploration holes in the surrounding Casa Grande Valley.

In 1986, the Bureau of Mines obtained Congressional approval and funding to study in situ copper mining. In 1988, the Santa Cruz deposit was selected for this research project sponsored by a joint venture program between landowners ASARCO Santa Cruz Inc. and Freeport McMoRan Copper & Gold Inc., and the US Department of the Interior, Bureau of Reclamation. The in-situ testing began in February 1996, but research funding was halted in October 1997 due to a change from Congress.
Property Condition and Stage of Development. The Santa Cruz Project is an exploration stage project without mineral reserves. No mining activity has ever taken place on the land constituting the Santa Cruz Project. There is no mine in production at the project. There is currently no significant equipment, infrastructure or facilities at the Santa Cruz Project, and no mine development or operating equipment at the project site.

The Migratory Bird Treaty Act prohibits “Take” without prior authorization by the U.S. Fish and Wildlife Service (“USFWS”). Santa Cruz has implemented beneficial practices in accordance with USFWS Nationwide Standard Conservation Measures which include employee education, preconstruction surveys, nest monitoring, and avoidance of active nests. This may affect access points and the ability to perform work on the property.
Existing and past land uses in the Project area and immediately surrounding areas include agriculture, residential home development, light industrial facilities, and mineral exploration and development. Some dispersed recreation occurs in the area. The climate is dry, and most of the Project area is flat, sandy, and sparsely vegetated. Portions of the Project area are in the 100-year flood plain of the North Branch of Santa Cruz Wash. Within the Project area, approximately 85 acres of land located 1.2 km north of the intersection of N. Spike Road and W. Clayton Road was used during an in situ leaching project in 1991. A Phase 1 Environmental Site Audit (“ESA”) was conducted on the Project area.

There is a large private land package covering the Project area and area of known mineralization. The ability to operate on private land has the potential to reduce lengthy permitting timelines that result from federal permitting processes. The precise list of permits required to authorize the construction and operation of this Project will be determined as the mining and processing methods are designed.
The permit approval process for some permits includes review and approval of the process design. Thus, the project design must be substantially advanced to support the application for those permits. These technical permits typically represent the “longest lead” permits. Technical permits with substantial technical design are needed as part of the applications. The anticipated issuing agencies include:
a. Mined Land Reclamation Plan (ASMI)
b. 45-513 Groundwater Withdrawal Permit (Arizona Department of Water Resources (ADWR)
c. Recycled Water Discharge Permit (Arizona Department of Environmental Quality (ADEQ)
d. Aquifer Protection Permit(s) (ADEQ)
e. Air Quality Operating Permit (PCAQCD)
f. General Plan Amendment (City of Casa Grande)

Geological Setting, Mineralization and Deposit Types. The Santa Cruz Project lies along a northwest to southeast trending, approximately 600 km long porphyry copper belt that includes many productive deposits such as Mineral Park, Bagdad, Globe-Miami, and the neighboring Sacaton. These deposits lie within the Basin and Range province that covers most of the southwestern United States and northwestern Mexico. The porphyry copper deposits within this trend are the product of igneous activity during an approximately 80 Ma to 50 Ma orogenic event that involved northeast-directed subduction and a northwest-southeast-striking magmatic arc. During Basin and Range tectonic extension, porphyry copper systems were dismembered, tilted and buried beneath basinal deposits that now fill the Casa Grande Valley. Prior to concealment, the porphyry systems of Arizona experienced supergene enrichment events that make them economically significant deposits.
The Santa Cruz system (comprising the Santa Cruz, Texaco, Park-Salyer, and Sacaton deposits) represents one or more large, Laramide-aged porphyry copper systems that were subsequently enriched by supergene processes. Supergene enrichment is a mineral deposition process in which near-surface oxidation produces acidic solutions that leach metals, carry them downward, and reprecipitate them, thus enriching sulfide minerals already present. Sometime following the development of supergene mineralization, the Santa Cruz system was dismembered, displaced, and eventually buried as a result of Basin and Range extensional tectonism.
Mineralization at the Santa Cruz Project is generally divided into three main types:
• Primary hypogene sulfide mineralization: chalcopyrite, pyrite, and molybdenite hosted within quartz-sulfide stringers, veinlets, veins, vein breccias, and breccias as well as fine to coarse disseminations within vein envelopes associated with hydrothermal porphyry-style mineralization. Hypogene mineralization appears to be the most concentrated within the Southwest Exploration Area, Texaco Ridge Exploration Area, and Texaco Deposit areas based on Ivanhoe Electric drill holes.
• Secondary supergene sulfide mineralization: dominantly chalcocite which rims primary hypogene sulfides and completely replaces hypogene mineralization. Other sulfides that fall within this category include lesser bornite and covellite as well as djurleite and digenite which have been identified by historic XRD analyses. Supergene sulfide mineralization developed as sub-horizontal domains, known as “chalcocite blankets”, within the phreatic zone (below the paleo water table). They result from the weathering, oxidation, and leaching of sulfides under oxidizing conditions in the vadose zone (above the water table) and the transport and re-precipitation of copper sulfides in a more reducing environment below the water table.
• Secondary supergene “oxide” mineralization: chrysocolla (copper silicate) with lesser dioptase, tenorite, cuprite, copper wad, and native copper, and as copper-bearing smectite group clays. This mineralization style resides immediately above supergene sulfide mineralization near the paleo water table. Superimposed in-situ within the copper oxide zone is atacamite (copper chloride) and copper sulfates (e.g., antlerite, chalcanthite). Atacamite accounts for much of the copper grades within the oxide zone and requires formation of a brine to precipitate.
Exploration and Drillin g. We completed a twin hole program in 2021 to validate the historical drill data and produce an initial Mineral Resource Estimate in 2021 (December 8, 2021) and accompanying Technical Report Summary (June 7, 2022).
Our exploration in 2021 – 2022 included:

Table of Contents
a. Geophysical surveys – ground gravity, ground magnetics, Typhoon™ three-dimensional Perpendicular Pole Dipole Induced Polarization (“3D PPD IP”), refraction, and passive seismic.
b. Drilling – a combination of diamond drill and rotary drilling totaling 88 holes and approximately 55,291 m.
Combined with the historical exploration, there are over 170 drill holes totaling over 133 km length within the Santa Cruz Project area. This exploration comprises the drilling data used for the mineral resource estimate.
Our exploration in 2023 included drilling – a combination of diamond drill, rotary, and sonic drilling totaling 94 holes and approximately 68,294 m.
Sampling, Analysis and Data Verification . Nordmin and Met Engineering are not aware of any drilling, sampling, or recovery factors that could materially impact the accuracy and reliability of the results. In the opinion of Nordmin and Met Engineering, the drilling, core handling, logging and sampling procedures meet or exceed industry standards and are adequate for the purpose of Mineral Resource estimation.
The authors of the IA consider the QA/QC protocols in place for the Santa Cruz Project to be acceptable and in line with standard industry practice. Based on the data validation and the results of the standard, blank, and duplicate analyses, the authors are of the opinion that the assay and specific gravity databases are of sufficient quality for Mineral Resource estimation for the Santa Cruz Project.
Mineral Resources. The December 31, 2022, Mineral Resource Estimate (“MRE”) set forth in the IA was prepared by Nordmin and includes a detailed geological and structural re-examination of the Santa Cruz, East Ridge, and Texaco Deposits. Nordmin has also confirmed that the MRE remained accurate as of December 31, 2023
The Santa Cruz Deposit MRE benefits from approximately 116,388 meters of diamond drilling in 129 drill holes, the East Ridge Deposit MRE has 18 holes totaling 15,448 m, and the Texaco Deposit MRE has 23 drill holes totaling 21,289 m. All drill holes were completed from 1964 to 2022.
Diamond drill hole samples were analyzed for total Cu and acid soluble Cu using Atomic Absorption Spectroscopy ("AAS"). A decade after initial drilling, ASARCO re-analyzed select samples for cyanide soluble Cu (AAS) and molybdenum (multi-element ICP). The Company currently analyzes all samples for total Cu, acid soluble Cu, cyanide soluble Cu, and molybdenum. Due to the re-analyses to determine cyanide soluble Cu within historic samples, there are instances where cyanide soluble Cu is greater than total Cu. It has been determined that the historic cyanide soluble assays are valid as they align with recent assays in 2022 drill holes.

Mineral Processing and Metallurgical Testing. Metallurgy and processing test work were directed by Met Engineering LLC and conducted at McClelland Labs in Sparks, Nevada. McClelland Labs is recognized by the International Accreditation Service (“IAS”) for its technical competence and quality of service and has proven that it meets recognized standards. The studies are ongoing. Study focus has been on:
• Confirming total copper recovery of the leach-float flow sheet proposed by historical operator, CGCC, circa 1980, on Exotic, Oxide and Chalcocite mineral domains.
• Investigating heap leaching of Exotic, Oxide and Chalcocite mineral domains. The test program for heap leaching is in progress and is reported as such in section 10. Some early results are described below. Column leach testing will complete in the fourth quarter of 2023.
Agitation leach tests undertaken in mid-2022 verified historical test results and after adjusting the particle size distribution, acid-soluble copper recovery of 92% was achieved. Ivanhoe Electric subsequently conducted a leach-float test program in which the same mill composite sample used in prior testing was subjected to the standard leach procedure developed earlier in the year. Three standard leach tests were conducted, each subjected to different grind sizes. The studies support achieving up to 94% total copper recovery with the leach-float circuit at the Santa Cruz deposit. Further, the studies support that a smelter saleable concentrate could be produced without any penalties grading 48% total copper and 23% sulfur.
One column cell test has been completed and is in the phase of water rinsing and removing leach residue for analysis. The seven remaining column cell tests are operating normally and are all in the final stage of secondary sulfide leaching. There were no solution flow issues in any of the eight column cells. There were no significant operational issues on any of the column cells. Estimated copper recoveries and extraction rates on the two column cells cured with a chloride dopant were 98% and 94% copper and 70 and 63 days, respectively.
There are some factors to follow up on with future testing to ensure all processing factors are effectively investigated. These are confirmation of corrosion resistant materials and linings for the thickeners in the counter-current-decantation system for pregnant leach solution recovery and studying sulfide flotation with expected process water chemistry at the site. Otherwise, there are no deleterious elements that could have a significant effect on economic extraction.
Mining Methods. The Project is currently not being mined. Mineral resources are stated for three deposits: Santa Cruz, Texaco, and East Ridge. For mine planning work, only the Santa Cruz and East Ridge deposits were evaluated.
The Santa Cruz deposit is located approximately 430 to 970 meters below the surface. Based on the mineralization geometry and geotechnical information, an underground longhole stoping (“LHS”) method is suitable for the Oxide and Chalcocite-enriched domains within the deposit. The Santa Cruz deposit will be mined in blocks where mining within a block occurs from bottom to top with paste backfill (“PBF”) for support. A sill pillar is left in situ between blocks.
Within the Santa Cruz deposit, there is an Exotic domain located approximately 500 to 688 meters below the surface and to the east of the main deposit. The Exotic domain consists of flatter lenses that are more amenable to drift and fill (“DAF”) mining. Cemented waste rockfill will be used for support. The backfill will have sufficient strength to allow mining of adjacent drifts without leaving pillars.
The East Ridge deposit is approximately 380 to 690 meters below the surface and to the north of the main Santa Cruz deposit. The East Ridge deposit consists of two tabular lenses and will be mined using DAF with cemented waste rock backfill for support.
The mine will be accessed by dual decline drifts from surface, with one drift serving as the main access and the other as a railveyor drift for material handling. Mineralization is transported from stopes via loader to an ore pass system and then to surface by the railveyor. Main intake and exhaust raises will be developed with conventional shaft sinking methods to provide air to the mine workings. The mine will target a combined production of 15,000 t/d from the Santa Cruz and East Ridge deposits.
Portal box cut is assumed in the IA to start in 2026. Decline and railveyor activities begin in 2027 through to 2028 to access the top portion of the mine. Decline and railveyor resumes in 2033 to access the bottom of the mine. Stoping begins in 2029 with a 1 year ramp-up period until the mine and plant are operating at full capacity. The currently defined mine life is approximately 3 years of construction and 20 years of production.
Using historical data and the results of recent hydrogeologic testing, the hydrogeological conceptual site model was updated and the groundwater flow model was developed and finalized. The groundwater flow model was used to evaluate multiple passive and active dewatering scenarios for the proposed mine plan. With an active dewatering scenario pumping approximately 3,000 gallons per minute (“gpm”) for the first two years of life of mine (“LoM”), the model shows that the
23
Table of Contents
annual average residual passive inflows for the first 10 years of the mine are at or below 12,000 gpm. From year 11 through 25 of LoM, the residual passive inflows range from approximately 15,000 to 18,000 gpm.

This work is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have modifying factors applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that this economic assessment will be realized.
Recovery Methods. The Santa Cruz processing facility will recover copper by conventional weak sulfuric acid agitated leaching of the oxide mineralized material, and by sulfide flotation of the residue produced after leaching. Leached oxide copper will be processed through SX/EW to produce high purity copper cathodes. Sulfide copper and by-product precious metals will be recovered in copper flotation mineral concentrate. Copper concentrates will be of suitable quality to be sold to a domestic or international copper smelters.
The process design is based on metallurgical tests results from The Hanna Mining Company’s research center (circa 1980) and new IA-level mineral process testing initiated by Ivanhoe Electric in 2022 and 2023.
The following process flow diagram illustrates sequence of operations to recover copper in the Santa Cruz plant. This flowsheet provides the basis for the process description that follows.

The nominal capacity of the mill process is 5.475 million tonnes per year (“Mt/y”). Process availability factors include both the mechanical availability and the use of this mechanical availability. For the design, an availability factor of 92% is used throughout the plant because the primary and secondary grinding lines have a single ball mill in each.
The current mine plan developed for the Project is based on a 365-day calendar year. The yearly mine production tonnage will vary from 4.0 million tonnes (“Mt”) at the start of production to a high of 5.9 Mt in Year 5 of production.
The mass balance was developed for the Santa Cruz process using MetSim mass balance software. The process simulation used overall recoveries of 96% for the acid soluble copper as cathode copper and 93% for the sulfide copper into concentrate. These recoveries are based on 1980 studies and supported by mineral process testing in 2023 on recent drill core samples and include process losses attributed to Pregnant Leach Solution wash efficiency (2023 liquid solid separation test results) and cleaner scavenger flotation losses (1980 and 2023 test programs).
Project Infrastructure. The Santa Cruz project has excellent existing infrastructure including access to roads and interstate highways, railroads, power lines, and an abundant supply of water from dewatering operations and water rights associated with the private land acquired by Ivanhoe Electric. The Project owns sufficient fee simple land to allow for all surface infrastructure including the process facility, Tailings Storage Facility (“TSF”), offices borrow pit, and other related mine structures.
Interstate highways near the Project (<10 km) are Interstate 8 and Interstate 10. The Union Pacific/Southern Pacific (“UPSP”) rail borders the northern edge of the Santa Cruz Project and the BNSF rail has a spur and terminal in Phoenix, Arizona.

Tailings Storage Facility. A significant portion of the mined material will be returned underground as backfill in the mine. Backfill is used to fill voids created during mining. By returning tailings as paste backfill underground, the size and impact of the surface Tailings Storage Facility (“TSF”) will be reduced.
The TSF is proposed to be located on relatively flat terrain directly east of the plant site and sited to avoid: the underground ore body outline; mine’s infrastructure; and the 1% annual exceedance probability (“AEP”) (1 in 100-yr return period) floodplain from Federal Emergency Management Agency (“FEMA”) (2007) flood hazard mapping. The TSF is sized to store all the tailings estimated to be produced over the mine life and not used for underground backfill (56.7 Mt, without additional contingency) on surface. The tailings will be retained by a perimeter embankment (up to 50 meters high) constructed primarily of compacted, structural fill sourced from on-site borrow areas. The TSF impoundment will be lined with a low-permeability liner, which will be raised within the perimeter embankment for seepage control. During operations, tailings slurry water and precipitation which collects in the TSF will be reclaimed to the mine for use in the mining process or treated (if required) and discharged. At closure, the TSF impoundment will be regraded to prevent ponding and covered with a soil cover and vegetated to limit infiltration and resist erosion. Closure channels will be constructed to shed water off the impoundment surface and over the embankment slopes.
Power. Power consumption for the Santa Cruz Project is anticipated to average 450,000 megawatt hours per year (“MWh/y”). Initially the source of power for the Project will be provided from a 69 kilovolt (“kV”) power line operated by Pinal County Electric District 3 (“ED3”). Several other higher voltage transmission lines border the property within close proximity.
Power for the Project could be provided from a number of sources, or combination of sources, ranging from grid supply to microgrid renewable energy supply. The goal of the mine development is to achieve much of the energy supply from renewable sources, such as solar or geothermal, either at the start or through a phased in approach during the mine operation. The base case of the project is that the mine will operate using 70% renewable power within the first three years of operations.
Water. The water balance for the Santa Cruz Project indicates that there will be a surplus of water from the Project from dewatering of the underground operations. The mining and processing operations will consume approximately 3.5 million cubic meters (“Mm3”) of water per year, while water supplies from dewatering will range from 20 million to over 30 million cubic meters per year (“Mm3/y”). The amount of water for distribution to local stakeholders during operations will average 27 Mm 3 /y. The water balance excludes the water rights associated with the surface title of the Project.
Market Studies and Contracts. A flat copper price of $3.80/lb has been selected for this study. In the opinion of SRK, this price is generally in-line with pricing over the last 3 years and forward-looking pricing is appropriate for use during an Initial Assessment of the Project with an estimated mine life of 20 years. As the Project progresses, more detailed market work in the form of market studies will be completed to support further study efforts. SRK cautions that price forecasting is an inherently forward-looking exercise dependent upon numerous assumptions. The uncertainty around timing of supply and demand forces has the potential to create a volatile price environment and SRK fully expects that the price will move significantly above and below the selected price over the expected life of the Project.
Cathode is assumed to be 100% payable with no premium or discount applied for the purposes of the study. This approach assumes that the cathode has not received registration or certification that would result in a premium; nor is the cathode assumed to contain any deleterious or penalty elements.
Concentrate terms for the study are generic terms and do not reflect the presence of any deleterious or penalty elements within the concentrate. The following table presents the concentrate terms applied for this study.

As the Project is an early-stage greenfield project, there are a large number of contracts required for the development and operation of the site. None of the major required contracts have been executed at the time of this study.
Environmental, Closing and Permitting. The Project is located on private land. Permitting is primarily with the State of Arizona, Pinal County, and City of Casa Grande. While the Project will be required to obtain several permits to operate it is on private land and is not anticipated to be subject to lengthy federal permitting timelines.
Baseline studies are underway for resources of concern and studies will continue as the Project develops. There are no known occurrences of federally listed threatened and endangered species and there are no planned impacts to potential federally regulated waters of the US. Portions of the Project site is a known nesting area for burrowing owls protected under the Migratory Bird Treaty Act and US Fish and Wildlife beneficial practices to avoid and minimize impacts to birds have been and will continue to be implemented as the Project develops.
The utilization of a renewable microgrid will allow the Santa Cruz Project to produce copper with one of the industry's lowest carbon intensities. Such intensities highlight Ivanhoe Electric commitment to implementing cutting-edge mining techniques, conserving energy, and utilizing renewable energy.
Aside from the pending reclamation plan for exploration activities at the Site, Ivanhoe Electric has no current obligations to tender post mining performance or reclamation bonds for the Project. Once the facility achieves the level of design necessary to advance to mine development and operation, Ivanhoe Electric will need to submit and gain approval of an Arizona Department of Environmental Quality (“ADEQ”)-approved Aquifer Protection Permit (“APP”) and an Arizona State Mine Inspector (“ASMI”)-approved Reclamation Plan. The closure approach and related closure cost estimates must be submitted following approval and before facility construction and operation.
Ivanhoe Electric plans to create an all-encompassing environmental, social, and governance framework designed to effectively address any community concerns and ensure that the Santa Cruz Project operates in a socially responsible manner.
Capital and Operating Cost Estimates
Mining Capital Cost Estimate. The mining capital cost estimate is based on first principal cost model build-up and budgetary quotes. The initial mining capital costs plus sustaining mining capital costs are equal to $960.48 million, which includes an estimated capital of $878.08 million plus 9.4% contingency of $82.40 million.
Development costs are derived from the mining schedule prepared by SRK. The prepared mining schedule includes meters of development during pre-production, this schedule of meters was combined with unit costs, based on site specific data, to estimate the cost of this development operation. The following table provides the breakdown of the estimated initial capital costs.

* Sustaining capital is modeled on an annual basis and is used in the model as developed in previous sections. No contingency amounts have been added to the sustaining capital within the model. General closure costs are modeled as sustaining capital and are captured as a one-time payment the year following cessation of operations. For the tailings impoundment, closure costs run several years past the end of the mine life, this cost has been captured by extending the model life beyond the end of the mine life.
Economic Analysis. Economic analysis, including estimation of capital and operating costs is inherently a forward-looking exercise. These estimates rely upon a range of assumptions and forecasts that are subject to change depending upon macroeconomic conditions, operating strategy and new data collected through future study or operations and therefore actual economic outcomes often deviate significantly from forecasts.
As permitted by Subpart 1300 and Item 601 of Regulation S-K, the new IA includes an economic analysis of the Santa Cruz Project without taking into consideration inferred mineral resources and also includes an economic analysis of the Santa Cruz Project including the inferred mineral resources. It should be noted that the new IA is preliminary in nature, and is based on mineral resources. Unlike mineral reserves, mineral resources do not have demonstrated economic viability. It should also be noted that the version of the economic analysis that includes inferred mineral resources includes inferred

mineral resources that are considered too speculative geologically to have modifying factors applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that this economic assessment will be realized.
The new IA anticipates that the Santa Cruz Project will consist of an underground mine and processing facility producing both copper concentrate and copper cathode.
The economic analysis metrics are prepared on annual after-tax basis in US$. The results of the analysis are presented in the table below. The results indicate that, at a copper price of US$3.80/lb., the Project without inferred material returns an after tax net present value (“NPV”) at 8% of US$0.5 billion calculated from the start of construction, an after tax internal rate of return (“IRR”) of 14% and a payback period from the start of construction of 10 years. When the inferred material is included in the economic analysis, the after tax NPV @ 8% increases to US$1.3 billion, the after tax IRR increases to 23% and the payback period decreases to 7 years from the start of construction.
This assessment is preliminary in nature and is based on mineral resources. Unlike mineral reserves, mineral resources do not have demonstrated economic viability. This assessment also includes inferred mineral resources that are considered too speculative geologically to have modifying factors applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that this economic assessment will be realized.
The economic model is based on mine plans that were prepared as outlined in previous sections. Inferred resources account for approximately 21% of the tonnage contained within the mine plan. The economic results of the Project both without inferred resources and including inferred resources are presented within this section. However, the removal of the inferred material from the mine plan is a gross adjustment and no recalculation of fixed capital and operating costs has been completed for the scenario without inferred mineral resources.
As the stage of study for the Santa Cruz Project is initial assessment, no reserves are estimated for use in this analysis. The economic evaluation was completed using resource material that includes material in the inferred category. To evaluate the risk associated with the use of inferred material in the mine plan, a model was completed where the inferred material was removed from the mine plan. SRK notes that this model result should be viewed with caution as the removal of the inferred material is a gross adjustment and no corresponding adjustments to capital, operating cost or mill performance were made.
The book value of the Santa Cruz property and its associated plant and equipment as at December 31, 2023 was $167.0 million.

Conclusions and Recommendations by the Qualified Persons. Under the assumptions presented in the IA, and based on the available data, the mineral resource estimates show reasonable prospects of economic extraction.
The recommended program is for the Company to complete a pre-feasibility study (“PFS”) level technical report. The work program required to complete a PFS will consist of associated infill and exploration drilling, analytical and metallurgical test work, hydrogeological and geotechnical drilling, geological modeling, mine planning, and environmental baseline studies to support permitting efforts.
Proposed Plan of Exploration and Development
As recommended by the authors of the IA, we are advancing the Santa Cruz project to complete a PFS technical report. We are completing infill drilling to allow for drill results to be incorporated into an updated resource model that would allow for the Indicated Mineral Resource to be developed into an initial Probable Mineral Reserve with a focus on the initial 5 years of production. We are targeting the Santa Cruz deposit high-grade exotic copper domain, the southern East Ridge oxide domain, the Texaco deposit and Texaco Ridge exploration area, and the Primary Domains.
We will explore different mining orientations for the Santa Cruz long hole stoping areas. There are areas that require long ore drives to access. Exploring different orientations can potentially lead to shorter ore drives and consequently shorter hauls to the ore passes. We are optimizing the stope size when additional geotechnical information is available. Larger stopes allow for more efficient mining and lower operating costs. And we are also evaluating recovering the sill pillar between the upper and lower blocks. The sill pillar is mineralized and it is left in-situ in the current mine plan. Additionally, we are also evaluating more efficient materials handling methodologies. By developing a centralized materials handling system that can utilize ore passes inside the mineralized rock, production efficiencies can be optimized to reduce loader tramming and rehandling times, thereby lowering operating costs. We are also continuing to investigate renewable power options for the Project to develop costs and timelines for installing solar and other green power generating facilities on or near the site.

As used herein, references to the “Tintic Technical Report Summary” is to the “S-K 1300 Technical Report Summary & Exploration Results Report, Tintic Project, Utah” dated February 23, 2024 and current as of December 31, 2023, by qualified persons SRK Consulting (U.S.) Inc. It was prepared in accordance with the requirements of S-K 1300. SRK Consulting (U.S.) Inc. is not affiliated with us or any other entity that has an ownership, royalty or other interest in the Tintic Project. The Technical Report Summary on the Tintic Project, Utah, U.S.A. is included as Exhibit 96.2 hereto. Scientific and technical information in this section is based upon, or in some cases extracted from these reports.
Location, Map, and Access. The exploration stage Tintic Project is a gold, silver, and base metal Carbonate Replacement Deposit (“CRD”), skarn, fissure vein, and copper-gold porphyry exploration project located in the historical Tintic Mining District of central Utah, USA. The Tintic District is the site of significant historical production and over 125 years of exploration activity. The Tintic Project is located near the City of Eureka, approximately 95 km south of Salt Lake City, and can be accessed from U.S. Highway 6, approximately 30 km west of the Interstate 15 junction. The center of the Ivanhoe Electric exploration potential area claims and applications lies approximately at 39° 55’ N latitude and 112° 06’ W longitude. It is crossed by many historical mine roads and defunct railroad paths, which provide access to most of the property. The exploration area covers approximately 81.97 km 2 of private patented claims, unpatented claims, and state leases consolidated by Ivanhoe Electric into a cohesive package of interests.
The Tintic Project area hosted historic mining communities and activities, but only two communities remain today at Eureka and Mammoth. The historic mining area straddles the Tintic Mountains divide between the Utah and Juab Counties. The county line occurs at the watershed divide.
Infrastructure. The Tintic Project is managed out of the city of Eureka (population approximately 660), which is approximately 2 km north of the northeastern Tintic Project property boundary. Eureka offers limited services. Equipment and other services are generally obtained from the towns of Tooele or Payson/Spanish Fork, which are each a 45-minute drive. We have established a permanent presence in the Tintic District and are currently headquartered out of Eureka with office facilities. We have also developed a secure core logging and storage facility at the mouth of the Mammoth Valley.
Water for the Tintic Project can be sourced from the city of Eureka’s maintenance yard at a cost of $0.01 per gallon (~3.8 liters). The exploration area also contains several small ephemeral springs that are productive in the early spring but does not contain any streams or rivers owing to the arid nature of the climate. The Rocky Mountain Power Company provides electric utilities to the Eureka community and a high-power transmission line services Eureka, Mammoth, and Silver City. Gas is supplied by a local company. Limited supplies and personnel are available from Eureka; however, the main source is the Salt-Lake City-Ogden- Provo metropolitan area, a corridor of contiguous urban and suburban development stretched along a 190 km segment of the Wasatch Front with a population of 2.7 million.

To retain an unpatented claim on federal land in the USA, a $165 maintenance fee per claim is due annually by September 1st. Based on the current landholding this would amount to $78,210 in annual payments for claim retention.
In October 2017, Ivanhoe Electric (HPX at the time) signed a purchase and sale agreement with Mr. Spenst M. Hansen (“Hansen”) to acquire 100% of his patented claims and a portion of his unpatented claims. The last payment installment was made on April 19, 2022, making Ivanhoe Electric the current owner.
In January 2018, Ivanhoe Electric (HPX at the time) signed an agreement with Applied Minerals Inc. for an option to purchase metallic mineral rights, which granted exploration access to the Dragon claims during the option period. The terms of the agreement indicate that (i) Ivanhoe Electric would be required to pay $350,000 lump sum at the completion of an initial 40-day due diligence, (ii) further installments of $150,000 are required to be paid in December each year until December 2027, (iii) at any time before December 2027, Ivanhoe Electric may elect to purchase 100% of the rights to minerals for $3,000,000, except for clay and iron oxide, and (iv) Applied Minerals Inc. retains the surface rights with joint operating conditions allowing Ivanhoe Electric reasonable access. In March 2020, the agreement was amended to allow Ivanhoe Electric an early exercise of the purchase of the metallic mineral rights for $1,050,000, while retaining Ivanhoe Electric’s exploration and reasonable access through the claims. Ivanhoe Electric immediately exercised this right and was deeded the metallic mineral rights to the subject claims.
In August 2018, Ivanhoe Electric signed a further purchase and sale agreement with Hansen to acquire the patented claims on the Mammoth, North Star, and Gemini properties. Payments were made over a five-year period with escalating payments as defined in the Definitive agreement. The last payment installment was made on August 7, 2023, making Ivanhoe Electric the owner of the patented claims.
In addition to the Hansen and Applied Minerals Inc. agreements, Ivanhoe Electric entered into an additional 22 agreements, totaling to 27 agreements, for the acquisition of claims, mineral and surface rights with numerous parties using various legal structures. All these agreements are summarized in a simplified form in the table below.

Royalties. Significant portions of the patented and unpatented mining lode claims are subject to NSR royalty agreements, ranging between 1% and 4%, which would be payable upon production and sale of product, i.e., there are no advance royalties. Ivanhoe Electric has purchased certain royalty interests already and formed an opinion on others. As part of its land consolidation effort, Ivanhoe Electric is continually clarifying and negotiating the relevant royalty terms to sensibly lessen the royalty burden.

Property Condition and Stage of Development. The Tintic Project is an exploration stage project without mineral reserves or mineral resources. There is no mine in production at the Tintic Project and no mining activity by us has ever taken place on the land constituting the Tintic Project.
There is currently no significant equipment, infrastructure or facilities at the Tintic Project, and no mine development or operating equipment at the project site. Historical mine equipment, shafts, and adits are ubiquitous throughout the area. In 2021, we completed some basic rehabilitation on the Sioux-Ajax Tunnel to facilitate access and mapping. This included creating a tag system, installing a communications system, and washing the walls. Further rehabilitation is not currently planned or budgeted for and IE has prohibited access to the Sioux-Ajax Tunnel since March 2022. There is no mining or operating infrastructure at the Tintic Project that would be intended to be used in future mine operations.
History. Mineralization in the Tintic District was discovered in 1869, and by 1871 significant mining camps were established in the nearby city of Eureka, and the now defunct towns of Silver City and Diamond. Mineral extraction focused on high-grade Ag-Pb-Zn oxide carbonate replacement deposits (“CRD”) hosted in Paleozoic limestone both at

surface and underground, with lesser production from steeply dipping Au-Ag-Pb-Zn-Cu fissure veins. The Tintic precious and polymetallic mining district saw nearly continuous mining operations from 1871 through to 2002 with variations in the level of activity and commodity extracted. Total historic production from deposits located within our acquired property, predominantly in the Tintic mining districts, totals approximately 1.89 Moz Au, 136 Moz Ag, 104 kt Cu, 416 kt Pb and 6 kt Zn.
The main precious and base metal bearing minerals in the Tintic District are enargite, tetrahedrite, galena, sphalerite, pyrite, marcasite, and native gold, silver, and copper. However, many more mineral species are present, including exotic tellurium-bearing species. There are clear metalliferous domain changes from the Southwest to the Main Tintic Districts. Cu-Au dominance transitions into Pb-Ag, then into Pb-Au and finally into Pb-Zn in the northern portion of the Main Tintic District. This zonation leads us to believe that the Main Tintic district likely contains the porphyry source of the polymetallic bearing fluids.
Permitting and encumbrances. Royalties are discussed above, under “Royalties”. In March 2021, Tintic Copper & Gold Inc. submitted a Notice of Intention (“NOI”) to Conduct Exploration to the Division of Oil, Gas and Mining of the Department of Natural Resources of the State of Utah. This permit (E/023/0130) was approved in July 2021, and has been amended multiple times by TCG, with the most recent amendment approved in July 2023. The current permit allows for up to 16.8 acres of surface disturbance, and 61 drill holes totaling 61,500m (201,720 ft), The approved permit will allow the recommended drilling program to be undertaken. Reclamation bonding is required by the state of Utah, and is assessed at $578,200.00, covering 100% of permitted surface disturbance and up to 16 open holes (20,000 m). Bonding is fulfilled through an insurance surety instrument.
There are two Recognized Environmental Conditions (“REC”) present on the Tintic project lands in the form of old mill sites. We do not anticipate doing any work in these areas, and therefore do not expect to trigger any potential environmental liability.
See “— Mining and Mineral Project Exploration Laws”.
Geological Setting, Mineralization and Deposit Types. The host rocks at Tintic are Pre-Cambrian through Paleozoic sediments and carbonate rocks and were emplaced to their current position primarily during the Sevier orogeny (Cretaceous), forming a series of folds and thrusts, including a synform which forms the key host sequence in the Main Tintic District.
The ‘Deep Creek-Tintic’ mineral belt is an east trending zone of basement highs marked by Cenozoic calderas and associated metal endowment all along the belt. The East Tintic Mountains, where the belt terminates, host the Tintic District, the second biggest mining district in Utah after the Bingham District, located approximately 65 km north of the Tintic Project. The Bingham stock lies approximately at the intersection of the Wasatch hinge line and the ‘Bingham-Park City’ mineral belt, coinciding with the Cheyenne suture zone and the Uinta arch, concentrating tectonic and igneous activity. The Tintic District lies at the eastern margin of the ‘Deep Creek-Tintic’ mineral belt where it terminates against two or more north-south trending range front faults. Metallic minerals at Tintic and Bingham are hosted along northeast striking, steeply dipping, thrust faults, related to the Sevier orogeny. Intrusions along the Uinta arch in the Wasatch intrusive belt are high potassium calc-alkaline and metaluminous I-type granitoids similar to the igneous intrusions at Tintic. Eocene to early Oligocene intrusions, the source of mineralizing fluids, were emplaced in an extensional stress regime with northwest-southeast least principal stress. Basin and Range extension began around 18 Ma, forming high-angle normal faults which resulted in block tilt and the present Basin and Range topography. Fluid inclusion studies from plutons in the Wasatch Mountains indicate a 15-20° eastward tilt of the range and paleomagnetic data from the Oquirrh Mountains are consistent with an 11 eastward tilt related to the Basin and Range. The East Tintic Mountains were uplifted and rotated 10-20 east, similar to the Oquirrh Mountains.
The Tintic District has been broadly divided into four sub-districts: North, East, Main and Southwest. The following describes the stratigraphy, structure, volcanism, mineral deposit types and zoning patterns, including mineralization and alteration, observed in the four sub-districts, and summarizes the effects of Basin and Range extension on the Tintic District. The East Tintic Mountains are underlain by a basement sequence of more than 800 meters of phyllic slate, quartzite and dolomite from the Neoproterozoic Big Cottonwood Formation, outcropping along the axis of the North Tintic anticline. A sequence of more than 3,700 meters of Paleozoic (ranging from Cambrian to Mississippian periods) carbonate and clastic sedimentary strata lies unconformably on top. This sequence is characterized by a thick basal Cambrian Tintic Quartzite, succeeded by a thick sequence of dominantly limestone and dolomite. During the Sevier orogeny, from Late Jurassic to Late Cretaceous, the East Tintic Mountains were uplifted and deformed in a series of north-trending, north- plunging asymmetrical folds cut by coeval thrust faults, high-angle strike-slip and tear faults. Three major folds deform the Neoproterozoic and Paleozoic sequence in the Tintic district.

Table of Contents
Our interests in the Tintic District are focused on the southern portion of the Main District where Paleozoic sedimentary rocks and late Eocene — Oligocene volcanic rocks are intruded by the Silver City intrusive complex. Over 2,000 m of Paleozoic stratigraphy is exposed at the property ranging from the early Cambrian Tintic Quartzite at the western flank through the Mississippian Humbug Formation on the east. The rocks above the Tintic Quartzite are predominantly comprised of limestone and dolomite with a few units that have a greater siliciclastic component. Thin-skinned thrusting during the Sevier orogeny resulted in a complex pattern of faults and folds in the Paleozoic stratigraphy dominated by the east-west Sioux-Ajax fault through Mammoth and a large, east-verging asymmetric anticline-syncline pair that is cut by northeast trending faults. The thrust faults that underlay this folding have been identified in mines in the East Tintic District and locally at surface when not covered by later volcanic rocks. North of the Sioux-Ajax fault, the ‘ore runs’ of the Main District occur as sub-horizontal bodies connected by chimneys or pipes where crossed by faults in the shared subvertical limb of the anticline-syncline pair and along the axis of the Tintic syncline at the eastern margin. Exposure of Paleozoic rocks south of the Sioux-Ajax fault is limited to a less than 2 km 2 area between the Silver City intrusive complex to the southwest and overlying volcanic rocks to the southeast; it does not show the magnitude of folding found to the north of the fault. Instead, the beds here dip moderately to the northeast and are cut by steep reverse faults referred to as fissures when mineralized which continue south to the contact with the intrusion. These fissures and the subvertical chimneys and pipes tend to be more Cu-Au rich than the sub-horizontal Ag-Pb-Zn rich ‘runs’ north of the fault. Where these fissures intersect the contact with the Silver City intrusive complex, deposits of massive Fe-oxide and halloysite occur such as the Dragon Mine.
Mineralization in the Tintic District is typical of a porphyry-epithermal magmatic hydrothermal system. Known deposits predominantly occur as CRDs and epithermal veins with a few small porphyry deposits including the SWT porphyry in the Southwest District and the Big Hill porphyry in the East District. Exploration prospects identified by us on the Tintic Project include CRDs in the Paleozoic stratigraphy, areas with porphyry exploration potential in the Silver City intrusive complex and at depth below the CRDs, and skarns at intrusive contacts in the carbonate rocks.
Exploration and Drilling. We commenced exploration on the Tintic Project in late 2017 with an airborne geophysical survey followed by on-the-ground exploration in early 2018. Surface exploration work included a ground geophysical survey and a geological baseline work program consisting of soil and rock grab sampling, age dating, petrology, mapping, prospecting, and identification of key intrusive and alteration phases. Additional work through 2018 and into 2019 included the re-logging of deep historical drill holes at the Dragon prospect and the compilation and 3D digitization of historical mines, underground workings, and mineralized zones termed ‘ore runs’. Exploration work in 2022 and 2023 included reverse circulation (“RC”) and diamond core drilling, and a ground gravity survey along with small programs of soil samples, mapping, and surface sampling.
In late 2021, we completed a small exploration drill program consisting of two RC holes and a fan of four diamond drill holes. An additional twelve diamond drill holes were completed in 2022 and 2023 with one hole (TTD-017) started, but not completed. The total count to December 31, 2023 is 16 completed diamond drill holes with drilling ongoing into 2024.

Typhoon™ has also completed a 72 km 2 fully 3D IP survey, with effective penetration depths averaging over 1.5 km, which revealed never before seen porphyry Copper-Gold exploration potential areas that are ready to drill. A new ground gravity survey was conducted in 2022 over an area of approximately 20 km 2 .
We have also compiled a drill hole database from over 125 years of exploration and development operations in the Tintic Project district by dozens of historical owners and operators. A total of 489 drill holes were completed historically on the Tintic Project by several prior owners and operators. However not all of the details are available.
Our current database contains known collar locations for 442 diamond, RC and rotary air blast drill holes totaling approximately 72,212 m. The accuracy and certainty of collar locations are variable, due to the many sources of information. Some collar coordinates were derived from georeferenced maps and figures, and abandoned mine-grid translations, each of which have uncertainties attached to them regarding their positions. Forty-seven holes have collar locations recorded in undocumented or unknown mine-grid datums and will be added to the database when their locations can be deduced. 193 drill holes are collared on the Applied Minerals “Dragon” halloysite mine property (12,635 m total), and consist primarily of geotechnical, geological, and mineral data pertinent to the clay and iron-oxide mining operations there. While the authors of the Tintic Technical Report note that drill hole positions should be treated with caution when utilized for geological modelling, due to the varied level of accuracy, they note that they can be utilized for regional scale geological modelling, which we have completed in Leapfrog Geo™.
Assay results have been compiled from 221 drill holes across the Tintic Project district. Records of analytical methods for assay data are limited and the assay database consists of variable element analyses. These range from comprehensive 43 element ICP-MS data from analyses performed on drill hole core from the Big Hill diamond drill hole program conducted from 2008 to 2014 in the East Tintic sub-district, to Cu-Au only results from RC drilling in the Treasure Hill area. In the opinion of the authors of the Tintic Technical Reports, historical drill hole analytical results should be treated with caution and only utilized for indicative purposes until twin drilling is completed to verify position, orientation and grade, as no supporting QA/QC information is available for the respective drill holes.
Sampling, Analysis, and Data Verification. All drill core, soil, and rock grab samples collected by us during exploration programs undertaken to date have been prepared by ALS Global-Geochemistry Analytical Lab (“ALS”) at Twin Falls, Idaho or Elko, Nevada and analyzed Reno, Nevada or Elko, Nevada. ALS is a reputable analytical laboratory with a global quality management system that meets all requirements of the international standards ISO/IEC 17025:2017 and ISO 9001:2015. We believe that ALS has a robust internal QA/QC program to monitor and ensure quality of assay and other analytical results.

We have been active with several of our other mineral projects in the United States including the Hog Heaven Copper-Silver-Gold Project (“Hog Heaven”), located in Montana, where we have been actively drilling since June 2023. Exploration work in 2023 also included drilling on Lincoln, in Utah, and Carolina, in North Carolina. Geophysical Typhoon™ surveys were completed in 2023 on White Hill, in Nevada, Unity, in Oregon, and Carolina. We also hold a portfolio of exploration projects throughout the United States including projects in Arizona, Nevada, California, Utah, Montana, and Oregon.
Figure: Map of our US Mineral Exploration Projects
Hog Heaven Project, Montana, USA (the “Hog Heaven Project”). The Hog Heaven Project is located on private land approximately 80 km south-southwest of the town of Kalispell, Montana. It is in the historical Hog Heaven District which consists of several high-sulfidation epithermal mineral deposits and prospects, as well as several historical mines, including the Flathead Mine. We believe the Hog Heaven District is underexplored at depth, with a substantial alteration footprint and multiple mineralized centers.
Brixton Metals Corporation (“Brixton”) owns the Hog Heaven Project through its subsidiary Brixton USA, covering an area of 24.32 km 2 through the following interests: 2.59 km 2 of deeded fee simple land both surface and minerals and 14.06 km 2 of fee simple mineral rights held by Brixton USA. The balance, 7.67 km 2 , is held via lease of three parcels owned by the Chester Company Ltd.

We entered into an earn-in agreement on February 26, 2021 with Brixton as well as a subsidiary of Brixton, pursuant to which we may earn up to a 75% interest in the Hog Heaven Project by making cash payments totaling $4,500,000 and incurring an aggregate of $40,000,000 in exploration expenditures by 2032. We own 1.8% of the outstanding shares of Brixton, which we acquired from Newstar Advantage Ltd., an entity affiliated with Mr. Friedland (“Newstar”) on October 1, 2021 for Cdn$2.0 million. Newstar acquired shares and warrants of Brixton in a private placement for a purchase price of Cdn$2.0 million. Brixton used the funds to purchase a portion of a royalty on the Hog Heaven Project owned by Pan American Silver Corp. on which the Company had an earn-in.
Under our earn-in agreement with Brixton, we have the right to earn a 51% interest in the Hog Heaven Project by making a total of $4,500,000 in cash payments and incurring $15,000,000 in exploration expenditures at stage 1. We may also earn an additional 24% interest (for a total 75% interest) in the Hog Heaven Project by incurring an additional $25,000,000 in exploration expenditures at stage 2. In order to complete stage 1, in addition to incurring $15,000,000 in exploration expenditures, we are required to make $500,000 in cash payments each year for four years, and $1,000,000 in cash payments on or before each of the fifth and sixth anniversaries of the date of the earn-in agreement. As of December 31, 2023, we had incurred $11.0 million in exploration expenditures and made $1,500,000 in cash payments.
In order to complete stage 2, which is at our sole discretion, we would be required to incur an additional $25,000,000 in expenditures of which we must incur $10,000,000 by February 26, 2030 and $15,000,000 by February 26, 2032. For purposes of this earn-in, a joint venture company, Brixton JVC, a Nevada corporation, was established. We earn into the Hog Heaven Project by acquiring stock of Brixton JVC. Pursuant to the earn-in agreement, we are the operator of the Hog Heaven Project. We also control and direct all exploration, development and other related activities while we are earning-into the Hog Heaven Project.
From the date that stage 2 is complete until the date that Brixton JVC makes a decision to commence the development and construction of an operating mine at the Hog Heaven Project, we and Brixton must each fund the activities and operations of Brixton JVC pro rata to our respective interests in the Hog Heaven Project, provided that, if requested by Brixton, we are required to fund its pro rata portion of the costs of the activities and operations of Brixton JVC, with such amount accruing with interest calculated at the annual rate equal to the U.S. Federal Reserve Secured Overnight Financing Rate plus seven percent. At the date a construction decision is made, the amounts we previously funded to Brixton will become due and payable to us, and shall be paid within 12 months of the date a construction decision is made, failing which Brixton would be subject to dilution pursuant to a standard dilution calculation.
If a party’s interest in Brixton JVC is diluted below 10%, then the interest of such party in Brixton JVC will be cancelled and its shareholding interest converted into a 2.0% NSR. In addition, one NSR royalty at a rate of 1.5%, three Net Profit Interest (“NPI”) royalties with rates of 5% and 10%, and one Net Revenue Interest (“NRI”) royalty with a rate of 10% (capped at $1,314,702) exist on various portions of the property. The three sections of Chester Company Ltd. lands are subject to a long-term lease that requires a $12,500 annual lease payment.
The ongoing drill program, which began in June 2023, is designed to search for additional silver, gold, and copper-rich high-sulfidation epithermal mineralization, which was the focus of historical mining activities. Our program is also intended to search for porphyry copper mineralization at depth.
Ivanhoe Electric’s current exploration drill program at Hog Heaven, as first reported in our October 2023 news release, has now completed twelve drill holes totaling 10,905 meters and is on-going. Exploration drilling has stepped out to the west and southwest, where mineralization remains open.
In November 2023, we conducted a Typhoon™ geophysical survey covering approximately 10 km 2 of land, which was designed to cover the core areas of known prospectivity. We expect to receive our Typhoon TM survey results in March 2024.
Lincoln Project, Utah, USA (the “Lincoln Project”). The Lincoln Project is located in southwest Utah. The closest towns include Milford, Minersville, and Beaver. It is approximately 330 km from Salt Lake City. We operate the Lincoln Project through our wholly-owned subsidiary Lincoln Cave Exploration Inc. (“LCE”). The project area consists of 34 patented claims and 121 unpatented Federal mining lode claims optioned from Grand Central Silver Mines Inc. (“GCSM”). There are another 330 unpatented Federal mining lode claims covering 22.87 km 2 and SITLA leases covering 11.86 km 2 .
GCSM is selling the mineral titles to LCE for cash payments totaling $3,000,000 over six years and retains a 2% NSR royalty, of which one half (1%) can be purchased by LCE for $1,000,000, and a further quarter (0.5%) can be purchased for $1,500,000 within ten years of the effective date (July 23, 2021). LCE holds a right of first refusal on the sale of GCSM’s royalty.

The Lincoln Project area encompasses numerous historic small underground workings with little record of production. Almost no modern exploration has occurred on the Lincoln Project.
Leveraging the CGI 3D inversion modeling of our 2022 Typhoon™ 3D-style pole-dipole DCIP survey we completed 6 diamond drill holes totaling 4,020.17 m. Partial assays are still pending as of December 31, 2023, but no significant results are expected.
Carolina Mining, North Carolina, USA (the “Carolina Joint Venture” or “Carolina”). We entered into a binding letter of intent in November 2021 to form a joint venture with the Carolina Mining Company (“CMC”), a private company based in Charlotte, North Carolina. Once the joint venture agreement has been executed, we will have the obligation to spend up to $1,000,000 over two years to acquire private mineral rights and surface access with the rights to drill test a series of electromagnetic (“EM”) conductors defined by CMC’s VTEM survey flown in 2021. Once these funds have been expended, we then will have the right to earn 51% in the joint venture formed with CMC by spending an additional $5,000,000 over a 3-year period and the further right to increase our interest in the joint venture to 85% by spending an additional $20,000,000 over 5 years or by completing a Feasibility Study.
CMC owns mineral rights and surface access to two historic mining sites that operated in the early to late 1800s. These include the Silver Valley mine, a volcanogenic massive sulfide (VMS) deposit discovered in 1880 with limited zinc, lead, silver, and gold production due to the difficulty of Smelting and recovering precious metals from zinc-rich ores and Conrad Hill, a deposit mined in the early 1830s that produced high grade gold (>1 oz/t) from a series of orogenic quartz veins carrying significant copper values.
In 2021, CMC flew a Geotech VTEM survey over a 16 km by 19 km area to explore for additional massive sulfide mineralization in the Ordovician volcanic-sedimentary rocks of the Carolina Slate Belt. This resulted in defining seven EM conductors ranging in strike length from 300 meters to 1300 meters. Inversion modelling by CGI showed two of the EM conductors extend from 200 meters below surface to depths >700 meters and are potentially tens of meters in thickness. Inversion modelling was not possible on the remaining EM conductors due to the proximity to cultural interference by cast iron water pipes and power lines located along most North Carolina County roads.
Starting in late September 2022, a 3-week program of ground Typhoon™ EM was carried out over three of the VTEM anomalies to better define their geometry and depth extent. CGI 3D inversion modeling was completed in January 2023 over one of the EM grids that provided targeting detail for drill testing in 2023. A 1.4 km by 1.4 km 3D IP survey was also conducted over the Conrad Hill Mine property.
The EM conductors are located on fee-simple private land in Davidson County, North Carolina that include both surface and mineral title. Options to purchase mineral rights and surface access for exploration and mining are being negotiated with the individual owners based on overall acreage and strike extent of the EM conductors within their land holdings. All the land that constitutes the Carolina Joint Venture will be subject to a 1.5% NSR and a further 2.0% NSR should CMC take dilution of their 15% interest in the Carolina Joint Venture.
The Typhoon™ EM survey on the Parks property, just north of the Pinerose property, revealed a significant conductivity anomaly that could be drilled ahead of any potential deal. Two EM targets were identified and drilled based off two different modeling methods: an inversion from CGI and a standard plate model approach. Drilling was carried out from Q2 2023 and consisted of three drill holes which tested the two geophysical interpretations from the Typhoon™ EM survey. The target from the CGI inversion model was drilled first with CMC-001, which failed to reach the target due to poor ground conditions but drilling succeeded on the second attempt with CMC-002. Drill results showed that numerous pyrrhotite laminations, with rare chalcopyrite, were responsible for the conductivity anomaly. CMC-003 targeted the plate model anomaly further west yielding similar results. These drill intercepts highlight the potential for sulfide accumulation in the volcaniclastic sediments of the targeted formation but did not intersect economic mineralization.
Further drilling is planned for Q1 of 2024 to test chargeability features identified at Conrad Hill and Red Hill, as well as conductivity features on the Parks property.
White Hill Project, Nevada, USA (the “White Hill Project”). Our White Hill Project is located in the Gillis Range, Mineral County, Nevada, approximately 32 km east of Hawthorne and 160 km southeast of Reno, Nevada. The project is situated within the Fitting Mining District and comprises 1,030 federal mineral claims covering 86.12 km 2 managed by the Bureau of Land Management. The project hosts demonstrated copper-bearing mineralization associated with skarns.
We entered into an agreement with the project owner, Exiro Minerals USA Corp. (“Exiro”) on February 22, 2023 which give us the right to earn an 80% interest in the White Hill Project by incurring $10.0 million of expenditures and making payments to Exiro totaling $4.95 million ($3.55 million in cash and $1.4 million in our common stock) within six years of signing the agreement. During the earn-in period, we have the exclusive right to operate, control and direct all
48
Table of Contents
exploration and mineral development activities at the White Hill Project. There are no minimum expenditures required in any given year, and we have the right to cease making payments at any time, resulting in us earning no interest in the project.
Should we earn into 80% of the project, the joint venture will form, and we will then be responsible for the next $30 million of development expenditures to advance the project. After that expenditure, each joint venture partner will contribute pro rata to the joint venture or be subject to standard dilution provisions related to its project interest. In the event that Exiro is to be diluted to less than 10%, it will retain a 10% project interest and we will carry Exiro’s funding obligation through to commercial production. At commercial production, Exiro will become obligated to repay such funded amounts to us within 12 months of commercial production. No royalties are to be granted as part of this agreement. We also have a right of first refusal over Exiro’s interest in the joint venture.
We undertook a Typhoon™ survey in May and June of 2023 covering 28 km 2 and completed surface mapping in November 2023. The results of the Typhoon™ are guiding our plans for drilling in 2024. Currently, we anticipate drilling 3-5 diamond drill holes in 2024.
Bitter Creek Project, Arizona, USA (the “Bitter Creek Project”). Our Bitter Creek Project is located in Yavapai County, Arizona, United States, approximately 20 km east of Wickenburg. The project area is accessible via a 40-minute drive from Wickenburg. We operate the Bitter Creek Project through a wholly- owned subsidiary, Bitter Creek Exploration, Inc. The Bitter Creek Project consists of 364 lode mining claims that are valid through to September 1, 2024. The total area of the project is 35.21 km 2 comprised of three exploration permits totaling 6.87 km 2 and 348 unpatented claims. The Bitter Creek Project has hosted two historic mines and several exploration projects.
We initially commenced field work and staking in late 2019 which carried through into 2020. This field work included prospecting, soil sampling (33 samples), stream sediment sampling (122 samples), rock grabs (110 samples) and heavy mineral sampling (48 samples). In 2021, a contractor flew an airborne electromagnetic and magnetic survey over the entirety of the Bitter Creek Project area. In spring 2022, we conducted a Typhoon™ 3D IP survey, which revealed a large chargeability anomaly. Interpretation and integration with surface mapping and sampling is guiding our plans for an initial drill program in 2024.
Unity Project, Oregon, USA (the “Unity Project”). Our Unity Project is located in Baker County, eastern Oregon southwest of Baker City, just outside the community of Unity and at the southern end of the Wallowa Whitman National Forest. The Unity Project is approximately 515 km southeast of Portland, Oregon, 225 km northwest of Boise, Idaho and is accessible by paved road. We operate the Unity Project through CMC, our wholly-owned subsidiary.
The Unity Project comprises 458 unpatented claims filed with the BLM. The Unity Project is centered on a Tertiary porphyry system of the same age as the Bingham Canyon Copper-Gold Mine in Utah owned by Rio Tinto as well as our Tintic Project in Utah. A 2% NSR royalty on all minerals encumbers the project. Three-quarters of the royalty (1.5% NSR) can be bought back for $12,000,000 within 12 months of the public announcement of the start of construction of a mine. We retain a right of first refusal for the remaining 0.5% of the NSR. Consultants, Seven Devils Exploration Ltd., will operate the first $5,000,000 in project expenditures with a 7.5% management fee.
We acquired the claims comprising the Unity Project in June 2018 through an agreement for staged payments payable to two vendors totaling $5,000,000 over six years. In June of 2023, the agreement was amended to allow for additional exploration, spreading the payments out an additional 2 years. As of December 31, 2023 we had paid $1,000,000 to the vendors. Option payments of $250,000 on the fifth anniversary, $1,500,000 on the sixth anniversary of the agreement and $2,250,000 on the seventh anniversary are required to complete the acquisition of the claims.
No exploration work had been conducted at the project area since the 1980s until we optioned the property in 2018 and we expanded the claim holdings. In 2018, we flew a helicopter-borne magnetic and radiometric survey over the Unity and Pole Creek claim blocks and the area between them. In 2021, we followed up the geophysical surveys with surface geologic mapping and sampling.
Starting in July 2022 a program of Typhoon™ 3D-style pole-dipole DCIP was carried out over an area approximately 3 km wide and 5 km long. CGI 3D inversion modeling is complete and will be used to guide a drill program in 2024.
Permits for the Unity Project are managed by the US Forest Service (“USFS”) Wallowa-Whitman National Forest unit, and by Oregon Department of Geology and Mineral Industries (“DOGAMI”). The operations plan was submitted to the USFS in 2021, approved in 2022 for an IP Survey, and subsequent drilling on up to seven (7) drill pads, with 2 holes permitted per pad up to 1,500 meters depth each. This plan was then submitted to DOGAMI in 2022 and approved in 2023. Follow up mapping, sampling, and analysis of the IP survey resulted in an amendment adding an additional 7 pads, which

Saudi Arabian Joint Venture
We established with Ma’aden a Saudi Arabian exploration Joint Venture through the limited liability company, Saudi JVCo, to unlock the significant mineral potential in Saudi Arabia. The Joint Venture has exclusive access to explore approximately 48,500 km 2 of underexplored land on the Arabian Shield that Ma’aden will make available to the Joint Venture.
Map: Location of the Ivanhoe Electric Ma’aden Joint Venture within the country of Saudi Arabia.
The Arabian Shield is considered highly prospective for both VMS and epithermal styles of mineralization. A notable VMS deposit in the Arabian Shield is the Jabal Sayid copper mine operated as a joint venture between Barrick Gold Corporation and Ma’aden that produced 68,492 tonnes of copper in 2022. Ma’aden’s Mahd Ad Dhahab ‘Cradle of Gold’ gold mine is an example of an epithermal deposit on the shield that has been mined since pre-Islamic times.
The Al Amar Belt is considered highly prospective for VMS and epithermal deposit types with historical work identifying zinc, copper, lead, silver and gold mineralization. Twenty-four exploration licenses that make up the Al Amar Belt cover 1,934 km 2 . Saudi JVCo. commenced exploration activities at the Umm Ash Shalahib exploration license, which largely surrounds Ma’aden’s existing Al Amar gold-copper-zinc mine (which is not part of the Joint Venture). The area comprises steep hills with flat valleys (wadis) providing good access. As of December 31, 2023, over 25 km 2 of the 65 km 2 Umm Ash Shalahib Exploration License area has been surveyed by Typhoon™ and is expected to be fully completed by the end of March 2024.

Ivory Coast Nickel-Copper Project, Ivory Coast (the “Ivory Coast Project”). The Ivory Coast Project is located approximately 650 road km northwest of Abidjan, Ivory Coast. As of December 31, 2023, our interest in the Ivory Coast Project was held through our 22.7% equity interest in Sama Resources Inc. (“Sama”) and our 30% interest in the Sama Nickel Corporation Inc. (“Sama Nickel”) joint venture described below. We expect to complete our earn-in by Q2 2024 and acquire a 60% interest in the Ivory Coast Project, following such time we will consider alternatives to advance the project.
The Ivory Coast Project consists of three exploration permits owned by Sama Nickel, a subsidiary of Sama, which is the joint venture vehicle in which we are partnering with Sama to advance the Ivory Coast Project, which cover a total of 517 km 2 , as well as two additional exploration permits held in a joint venture with Société pour le Développement Minier de la Côte d’Ivoire, a parastatal organization established by the Ivory Coast and which together cover 318 km 2 .
In March 2018, we entered into a binding term sheet for an earn-in and joint venture agreement with Sama which was subsequently formalized in March 2021 (the “Sama Earn-In and JV Agreement”). Pursuant to the terms of the Sama Earn-In and JV Agreement, we have the ability to earn a 30% shareholding interest in the Ivory Coast Project by incurring expenditures of Cdn$15,000,000 over a maximum of six years. By incurring additional expenditures of Cdn$10,000,000 within the same time period, including the financing of a PEA and the acquisition of an exploitation permit on part of the Ivory Coast Project, we will be titled to earn an additional 30% shareholding interest in the Ivory Coast Project, such that our aggregate shareholding interest therein shall be 60%. In August 2021, we reached the initial Cdn$15,000,000 expenditure threshold and as a result we acquired a 30% shareholding interest in Sama Nickel. We anticipate completing the required expenditures to earn an aggregate shareholding interest of 60% by Q2 2024.
In April 2018, pursuant to an investment agreement, Sama granted to us a right to nominate to the Sama board of directors two (2) directors as long as our shareholding interest of Sama remains above 10% but less than 50%, and four (4) directors if our shareholding rises to greater than 50%. As of the date of this Annual Report, Mr. Eric Finlayson and Mr. Quentin Markin are our director representatives on the board of Sama. Other than as shareholders of Sama, we do not have any interest in Sama’s gold projects in Liberia.

Alacran Copper-Gold Project, Colombia (the “Alacran Project”). On July 31, 2017, we (then HPX) entered into an investment agreement with Cordoba. Under that agreement, Cordoba granted us a right to nominate directors to its board of directors based on our pro rata interest in Cordoba. The investment agreement provides for our nominees to the Cordoba board to be reduced to less than a majority of the directors if our ownership interest in Cordoba is diluted to below 50%, with further proportional reductions thereafter. Assuming the board of Cordoba is to be comprised of seven directors and we hold a 50% or greater interest in Cordoba, we are entitled to nominate four, with at least one of such nominees being independent. We own 62.8% of Cordoba as of December 31, 2023.

On December 8, 2022, Cordoba announced a strategic arrangement with JCHX, whereby JCHX, through a wholly owned subsidiary, will purchase a 50% ownership interest in CMH Colombia S.A.S. (“CMH”), a company existing under the laws of Colombia, for aggregate consideration of $100 million. CMH will own 100% of the Alacran Project and will be the joint venture vehicle for Cordoba and JCHX in the strategic project level partnership. For its 50% interest, JCHX will pay the $100 million purchase price in three installments. The transaction closed on May 8, 2023, and $40 million was paid in cash as a first installment. A second installment of $40 million was fully paid in cash by January 4, 2024 following the board of directors of Cordoba approving the Feasibility Study of the Alacran Project, and the filing of the Environmental Impact Assessment (“EIA”) to the relevant Colombian Government authority. A third and final installment of $20 million is payable in cash once the approval of the EIA is obtained, which must be within two years of the transaction’s closing date. Should the EIA not be approved by the second anniversary of the closing date, JCHX will have the option to elect not to complete this final installment, which will result in JCHX being diluted to 40% and Cordoba increasing to a majority 60% shareholding in CMH.
A Joint Venture Shareholders’ Agreement (“JV SHA”) governs the strategic relationship between Cordoba and JCHX, and sets forth the general responsibility and authority of the CMH board of directors, in addition to the entitlements of each shareholder. The JV SHA provides that (1) the CMH board comprises four individuals, of which two directors nominated by Cordoba and the other two directors nominated by JCHX; and for so long as the shareholdings in CMH remain 50%-50%, a Cordoba representative serves as the Chairperson of the CMH board, and possesses a casting vote on all matters subject to a list of reserved matters; (2) Cordoba is appointed as the operator and manager of the Alacran Project pursuant to a management services agreement and is responsible for setting the annual programs and budgets for the CMH board’s approval; (3) JCHX (or its affiliate) has right of first offer to bid on the Engineering, Procurement and Construction and Detailed Design Agreement contracts, provided that Cordoba has the right to open the process out to competitive tender; with JCHX having the right to match any competitive bid; and (4) JCHX (or its affiliate) shall be entitled to up to 100% of the offtake from the production under the current Feasibility Study of the Alacran Project, provided that they are paying fair market value and they are the most competitive offer (including a matching right for other third-party proposals).
The Alacran Project is situated in the municipality of Puerto Libertador, which is approximately 390 km northwest of Bogotá, and 160 km north of Medellín in Colombia, amongst 22 mining concessions owned by the Company, of which, 5 licenses are part of the Alacran Project. The Company conducted several exploration programs between 2012 and 2023, consisting of geological mapping, geochemical sampling, geophysical surveys, and various drilling campaigns, that supported the completion of the 2019 Preliminary Economic Assessment, the 2022 Pre-Feasibility Study, and the current 2023 Feasibility Study, which marks the beginning of the development phase for the Project.

Initial capital cost is estimated to be approximately $420.4 million for the construction of a conventional truck-shovel open pit mine. The Project is anticipated to hold an after-tax NPV of $360 million with an IRR of 23.8% and a payback period of 3 years. The Project’s mine life is projected to be 14.0 years in addition to the estimated two years of construction and pre-production mining, of which, freshly mined ore will be stockpiled alongside historical tailings. The LOM cash costs for copper, net of by-product, is $1.35/lb with by-product credits at $1.31/lb, and a total LOM cash cost at $2.66/lb (cash costs excludes sustaining capital). The average mining rate for the project is projected to be 39.5 Mt of mined material per year of which ore material will be fed to dual processing plants consisting of a main processing facility for fresh and transition material, and a separate wash gravity plant for saprolite ore and historical tailings;
The Company filed the EIA application with the relevant Colombian Government authority on December 11, 2023 and was issued the official filing number on December 12, 2023.

Mineral Project Obligations and Payments
As described above, for many of our mineral projects, we do not own the underlying mineral titles or rights but maintain an option or a right to acquire such titles or rights. Such options or rights may be held through an option arrangement, an earn-in, or through the payment of deferred consideration.
The table below summarizes the cash payments that may be made in respect of each project. Commitments that are non-discretionary are payments we are required to make. Payments that are discretionary are payments that we are not required to make, but if we fail to make the payment in the amounts and when due, we will lose the rights associated with the project.

Mining and Mineral Project Exploration Laws
Mining exploration and resource development operations in Utah and Arizona are governed by both federal and state law, and the Company is required to comply with all regulations, rules and directives of governmental authorities and agencies applicable to the exploration of minerals in the United States generally.
Arizona
The Santa Cruz Project’s exploration and mining operations will be conducted entirely on private lands, and the planned mining operations will extract private mineral resources. Based on our assessment of federal and state law and regulations, the State of Arizona will be the lead permitting agency. Similar to Utah, the state of Arizona has been granted primacy of most of the major mining and environmental regulations applicable to the Santa Cruz Project, the primary exception being the federal underground injection control program and the local entitlement process. Several federal and state mining and environmental regulations will be applicable to the Santa Cruz Project depending on final design and operational details. These mining and environmental regulations may apply to exploration, reclamation, air, groundwater protection, natural resources, and development plans. We believe that there will be no federal nexus as it relates to permitting. Environmental studies will be conducted to fully assess and provide technical information on environmental conditions in order to support permit applications. Federal mineral claims do underlie one area adjacent to the planned mining area, but those properties are not currently in the mine plan.
Specific permits required for the Santa Cruz Project cannot be determined until the project design is completed. Specific information to be developed includes:
• Mine design
• Mining methods
• Mineral recovery methods
• Project water balance
• Process facility design
• Water requirements
• Infrastructure
• Surface facilities
• Reclamation methods
• Project emissions
The following table identifies the major permits and approvals that we will need to obtain either prior to the construction or before start-up of the mine and processing plant(s). The permits listed are not meant to be all-inclusive and cover only the major permits required for the mine and processing plant that are known at the current time.

Table of Contents
Major Permits or Approvals Issuing Agency
Underground Injection Control Permit U.S. Environmental Protection Agency
Dust Control and Air Quality Permits Pinal County Air Quality Control District
Aquifer Protection Permit Arizona Department of Environmental Quality
AZPDES Industrial Stormwater Mining Multi-Sector General Permit Arizona Department of Environmental Quality
Reclamation Plan Approval Arizona State Mine Inspector
Water Appropriation Permits Arizona Department of Water Resources
Underground Injection Control (“UIC”) Permit. A UIC permit is administered by Region 9 of the EPA under the federal Safe Drinking Water Act but the issuance of a Class V UIC permit, which is what the project would require for paste backfill, is “authorized by rule”. “Authorized by rule” means that an injection well may be operated without a permit as long as the owners or operators, submit inventory information to their permitting authority and verify that they are authorized to inject, operate the wells in a way that does not endanger underground sources of drinking water (“USDW”), and properly close their Class V well when it is no longer being used. After reviewing an owner or operator’s inventory information the permitting authority may determine that an individual permit is necessary to prevent USDW contamination. The technical information to support a UIC application is extensive and requires significant data on subsurface geology and hydrology. Detailed design would be needed and much of the data requirements would overlap with the Arizona Aquifer Protection Permit (below).
Dust Control and Air Quality Permits. Emissions of fugitive dust caused by activities that disturb the soil, such as earthmoving, vehicular/equipment traffic on unpaved surfaces, project activities disturbing unpaved services and wind require a dust control permit from the Pinal County Air Quality Control District (“PCAQCD”). Dust caused by vehicles traveling on unpaved roads, construction and wind events create a type of air pollution called particulate matter. Rules and regulations have been adopted to limit the amount of particulate matter produced by certain types of activities. A permit is submitted annually through the online portal to cover the exploration activities. A separate dust control permit will be submitted for the commencement of mining operations.
As the project is anticipated to have the potential to create emissions of regulated air pollutants above a minimum threshold during the mining phase for the processing plants, a final permit from PCAQCD must be obtained before construction begins. The permit application would identify emission sources, emission controls and other relevant information. Development of a dispersion model to estimate impacts to background ambient air quality from project emission may be required. The permitting process includes a 30-day public comment period, and the time needed by PCAQCD to complete the technical review depends on the complexity of the project. We anticipate the permit could be obtained within 12 months of application submittal but will be dependent on the category of permit needed and the agency backlog at the time of submittal.
Aquifer Protection Permit (“APP”). During mine commercial operations, unless specifically exempted or designed, constructed and operated so that there will be no migration of pollutants directly to the aquifer or to the vadose zone, mine facilities such as surface impoundments, waste rock or overburden disposal units, tailings impoundments, and leaching facilities are generally considered to be discharging facilities and must be operated pursuant to either an individual APP or general permit. For facilities during decline development, we believe a Type 2.02 General APP Permit would be required. For full project operations, we anticipate that an Individual (as opposed to General) permit would be required and that a public hearing would be held. Technical information to support an APP application is extensive and requires that facility design be advanced to the point that the potential for impacts to groundwater quality can be adequately assessed. Arizona Administrative Code R18-1-525 limits the time for a complex Individual APP with public hearing to 329 business days. This time could be extended if the application review identifies additional information that is required to be submitted or if agency backlog is high at the time of submittal. We anticipate being able to obtain this information within 24 months of developing the permit application.
AZPDES Industrial Stormwater Mining Multi-Sector General Permit (“MSGP”). A Storm Water Pollution Prevention Plan (“SWPPP”) must be prepared as outlined in the mining sector MSGP prior to receiving permit coverage. The drainage control plan developed as part of the mining and reclamation plan will be used to develop the SWPPP. The SWPPP must be fully developed and permit coverage granted prior to breaking ground at the site. A Notice of Intent to be covered under the mining MSGP will be submitted to the Arizona Department of Environmental Quality through the online portal.
Reclamation Plan Approval. All surface facilities must be reclaimed and a reclamation plan must be developed to describe the methods and the schedule for reclamation. In addition, a reclamation bond, the costs for a third-party to complete the reclamation, must be estimated. The reclamation plan and reclamation cost estimate must be provided to the Arizona State Mine Inspector for approval, a process expected to take 120 days. Financial assurance must also be secured
61
Table of Contents
by means of a surety bond, certificate of deposit, cash deposit and corporate guarantee, to ensure that the funds are available to complete reclamation in the event of operator default. The Santa Cruz Project is currently operating under an Exploration Drilling Reclamation Plan that has been approved by the Arizona State Mine Inspector. A Mined Land Reclamation Plan (“MLRP”) for full operations will be completed and submitted for approval prior to construction of the project.
Water Appropriation Permits. We have acquired a substantial land package with associated water rights. Most of these rights authorize water use for irrigation or residential service connections, so administrative filings to convert them to the proposed mining uses have been completed. We are also exploring other potential water rights sources in the area.
City/County Zoning Changes. The Santa Cruz Project would be required to undergo the City of Casa Grande Entitlement Process in order to rezone the area from a “Planned Area of Development” designation to an “Industrial” designation. In accordance with the provisions of the Arizona Revised Statutes, the city council may from time to time change the zoning of parcels within the municipality. These changes in zoning classification are for the purpose of meeting the land use needs of the residents of the city in conformance with the city's general plan. A Major General Plan Amendment Application must be submitted and approved prior to a rezoning petition. A Major Plan Amendment requires a Planning Commission and City Council public hearing process and can be expected to take up to 200 days. The rezoning petition must be submitted after the Major Plan Amendment approval is received and will require preparation of a Major Site Plan. The Major Site Plan and rezoning process both require a public hearing process and can be expected to take up to 250 days for final approval.
The foregoing is intended to identify the major, or long-lead time, permits and approvals, and is not exhaustive. Additional permits or authorizations will be required. However, additional permit requirements and approvals are not anticipated to require extensive technical detail or review and lengthy issuance timelines.
These additional permits may include:
• Hazardous materials permits
• Solid or hazardous waste permits
• City/County building permits, utility permits, road access permits
• City/County Special Use permit or Development Plan approval
• Floodplain use permit
• Stormwater permit
• Septic or sewage treatment permit
• Onsite landfill permit
• Potable water system permit
• Threatened or endangered species consultation
• Cultural resources consultation
Numerous large mine operations have been permitted in Arizona, and specifically in Pinal County where the Santa Cruz Project is located. Given the prevalence of copper mining, these jurisdictions have developed regulatory programs that have well-defined permitting requirements and that are relatively predictable in terms of the permitting process and associated timelines.
Utah
The state of Utah has primacy over major mining and environmental laws applicable to the Tintic Project state and private lands, including mining, air and water permitting. With primacy, the U.S. Environmental Protection Agency (“EPA”) and other federal agencies have delegated primary enforcement responsibility for mining and environmental law oversight to the state of Utah. Mining operations must obtain proper permits and approvals and submit proper reclamation surety prior to mine start-up per state and federal statutory and regulatory requirements.
The BLM, as agent for the U.S. Secretary of the Interior, has retained responsibility for managing and overseeing federally owned locatable mineral resources (which includes metalliferous minerals) under the General Mining Law of 1872. When mining projects impact federal lands (minerals or surface), approvals from BLM are required per the Federal Land Policy and Management Act. Federal actions requiring permits or approvals trigger compliance with the NEPA. The level of scrutiny a project receives is based upon BLM’s discretion, the significance of impacts to the environment, and/or the public’s interest or involvement. A portion of the properties within the Tintic Project are located on federal lands and the Company holds via lease or ownership a number of federal unpatented mining claims and, therefore, the Company’s operations on these federal lands will be subject to BLM regulatory oversight and permitting approval.
62
Table of Contents
The Tintic Project is located primarily within Juab County, Utah, though small portions of the project are also located within Utah County. Both Counties’ ordinances require mining operations to obtain a Conditional Use Permit (“CUP”) prior to commencing mining operations. The Company will work with Juab County officials to secure the required CUP authorizations (and Utah County, as needed). In addition to the CUP, the Tintic Project will be required to obtain other ancillary permits and approvals (such as building and road access permits) from the county in accordance with the county’s ordinances.
The Endangered Species Act of 1973 was passed by Congress in order to protect and recover endangered species and their habitat. Site specific surveys will be completed for the Tintic Project area to identify any threatened, endangered, or candidate species or potential habitat. However, based on current information, it appears that the risk of impacts to endangered species and their habitat is limited.
The following table identifies the major permits and approvals that we will need to obtain prior to the construction and start-up of the mine and any processing facilities. The permits listed are not meant to be all-inclusive and cover only the major permits required for the mine and processing facilities. In addition, various rights-of-way (“ROWs”) across state and federal lands may be needed from SITLA and BLM in order to construct project water and utility service infrastructure, and to upgrade existing roads. The Company has been in contact with SITLA and BLM regarding a number of aspects of the Tintic Project and does not anticipate that obtaining these ROWs presents a material issue.

Exploration Permits. Exploration activities for minerals require an approval from Utah Division of Oil, Gas and Mining (“UDOGM”). Exploration activities within the Tintic Project area are being completed under exploration permits.
Approval for Large Mine Operation. The Notice of Intent to Commence Large Mining Operations must be obtained prior to the commencing of mining operations and will contain a complete description of the existing environmental resources and impacts. Environmental baseline studies will be necessary to support the Notice of Intent application. The Notice of Intent will include a description of mining methods, a comprehensive reclamation plan, and identifies the financial security acceptable to UDOGM to cover the costs of reclamation to be completed by an independent third-party as required under the Utah state administrative rules (R647). Execution of the acceptable financial security instrument will be required in advance of commencing mining activities.
Approval of a Notice of Intent to commence Large Mine Operations in Utah can occur within 6-9 months of an application submittal.
Water Appropriations. The Tintic Project is located within the Sevier River Basin. Surface and groundwater use and appropriations within the State, including this basin, are regulated by the Utah Division of Water Rights. Pursuant to the current Sevier River Basin policy, the basin is closed to new surface and groundwater appropriations, so to meet the water requirements for the Tintic Project, we will rely on lease agreements or acquisitions of existing water rights within the area of the Tintic Project. We have commenced discussions with water rights holders regarding the lease or acquisition of existing water rights.
General Multi-Sector Industrial Storm Water Permit. A SWPPP must be prepared as outlined in the general industrial permit prior to receiving permit coverage. The drainage control plan developed as part of the mining and reclamation plan will be used to develop the SWPPP. The SWPPP must be fully developed, and permit coverage granted prior to breaking ground at the Tintic Project site.
Army Corps of Engineer’s (“ACOE”) Jurisdictional Waters. Site surveys will be completed for the entire Tintic Project area, including all utility corridor and access roads. It is anticipated that all mining operations will avoid all

currently identified potential jurisdictional waters within the area of the Project. Therefore, no permits or approvals from the ACOE are expected to be required.
County Conditional Use Permit and Other Permits. We have been proactive in maintaining good communication with the local community. To date, county officials as well as local landowners have expressed strong support for the Tintic Project. With this level of support for the Tintic Project, the CUP should be issued by Juab County without significant challenges. Anticipated time for approval would be 3-6 months once all the supporting studies have been completed.

Typhoon™
We own, through a wholly-owned subsidiary, patents to a proprietary exploration technology known as Typhoon™. When we reference “our” Typhoon™ technology, we mean the technology that is covered by patents owned by our wholly-owned subsidiary Geo27, Inc. (“Geo27”). We also are the exclusive worldwide licensee of certain technology in the field of geological survey for mineral exploration from I-Pulse Inc. (“I-Pulse”). I-Pulse is the parent of our predecessor company, HPX.
Typhoon™ is the brand name for our proprietary electrical geophysical surveying transmitter, which can detect the presence of sulfide minerals containing copper, nickel, gold and silver, as well as water and oil (although the Company does not hold any rights to water and oil exploration). The technology was developed by I-Pulse to unlock exploration in areas where potential deposits are hidden by cover, where target depths exceed the range of conventional geophysical surveying systems, or where the scale and topography of an exploration target area prevents efficient and cost-effective conventional work. Typhoon™ allows us to potentially discover deposits otherwise thought to be undetectable through conventional survey methods and technology.
We own the issued patents shown below. These patents cover certain aspects of our Typhoon™ technology. The actual protection afforded by these patents varies depending on the scope of coverage of each individual patent as well as the availability of legal remedies in each jurisdiction.

We believe the following specifications differentiate Typhoon™ from conventional geophysical systems:
• high current that is adjustable according to the depth and scale of the exploration target;
• high voltages that are also adjustable to overcome near-surface resistance;
• the ability to transmit both electromagnetic and direct current signals;
• extremely clean signal, which yields a high signal to noise ratio in recorded data;
• the ability to synchronize with multiple types of data receivers, so that the user can choose the receiver system most appropriate for the exploration environment; and
• three deployment configurations, from a large containerized system to a smaller lightweight system that is helicopter portable.

We currently have four Typhoon™ units, which allow us to evaluate multiple prospects at any given time. Saudi JVCo has ordered three new Typhoon™ units, one of which was delivered in 2023 and two that are expected to be delivered in the first half of 2024. We have also ordered the construction of a further six additional Typhoon™ machines and anticipate that the first will be delivered to us in the second half of 2024 following delivery of the new units for Saudi JVCo.
The data processing and artificial intelligence software developed by our subsidiary CGI complements our Typhoon™ technology and represents the only software product that can process the full spectrum of geophysical data produced by Typhoon™ efficiently.
Computational Geosciences
CGI is headquartered in Vancouver, British Columbia, Canada. It was founded in 2010 in order to capitalize on advanced software technology developed at the University of British Columbia that was designed to improve mineral exploration. The technology has undergone significant improvements over the years and extended its market reach into an O&G sector as well as water exploration activities. As of December 31, 2023, we owned 94.3% of CGI’s outstanding shares while 5.6% are equally held by CGI’s two co-founders. CGI was co-founded by Livia Mahler B.Sc., MBA, who currently serves as CGI’s Chief Executive Officer, and Dr. Eldad Haber Ph.D., who currently serves as CGI’s Chief Technology Officer, and is a professor at the University of British Columbia.
CGI’s technology consists of sophisticated software codes and artificial intelligence tools (“AI”) that are used to process geophysical data (including that generated by Typhoon™) in order to build accurate 3D subsurface images that indicate the presence of various metals and minerals, as well as water and oil. The AI tools are used to generate prospectivity maps for specific minerals, based on deep learning algorithms analyzing vast amounts of geoscience data.
CGI provides fee-for-service and software licensing agreements to customers in the area of critical minerals, energy and water exploration. CGI’s services apply its geophysical data inversion codes on geophysical data (included that of Typhoon™) collected by third party data acquirers as well as other sources such as public or private libraries, in order to construct and refine 3D subsurface images. These services help CGI’s customers in geophysical survey design through more accurately identifying potential resource targets for exploration while minimizing the operational footprint of those exploration activities. CGI also offers mineral prospectivity mapping services which are based on deep learning AI algorithms to help identify and rank prospective areas for critical minerals. In order to prepare diverse layers for AI algorithms, CGI uses unique tools such as data augmentation for sparse, unstructured data which enhance the results and provide critical knowledge of the subsurface for clients.
CGI applies its services to not only mineral projects but also to the global energy industry and in the search for underground water resources. In the energy sector, CGI has independently developed and collaborated to deploy a real-time 3D inversion service for resistivity logging-while-drilling (“LWD”) data, significantly optimizing well placement and well completion designs to maximize reservoir productivity. CGI is also able to monitor fluid substitution within reservoirs, whether for enhanced oil recovery or carbon capture and storage. CGI has entered into a non-exclusive licensing agreement with a major oilfield service provider for the worldwide license of the LWD code. With respect to the identification of underground water resources, CGI’s technology can also be deployed to predict prospective areas or delineate known water aquifers.

CGI does not patent its software codes. CGI owns codes for magnetics, gravity, DC/IP and electromagnetics.
CGI’s intention is to grow its client base in the mining sector for existing geophysical inversion and AI based services in order to increase its revenue from third party sources. CGI is currently developing two new geophysical modelling products and has identified another solution for the AI-based platform digitization application. CGI is also building large geoscience databases from vast amounts of publicly available data in various countries and regions of the world in order to use these datasets to map minerals, water, geothermal and other targets. CGI competes with geophysical data processors, airborne and ground surveyors, off-shore surveyors, and AI service providers. These include companies such as TechnoImaging, LLC, Geotech Ltd., KoBold Metals and Quantec Geoscience.
On February 6, 2023, CGI, together with Clean TEQ Water Operations Pty Ltd, incorporated Go2Lithium Inc. (“Go2Lithium”), a British Columbia company in which each party owns 50%. Go2Lithium was formed for the purpose of financing, acquiring and/or joint venturing a portfolio of technologies to produce battery grade lithium salts from aqueous sources and to build extraction plants based on proprietary continuous ion-exchange direct lithium extraction technology.
VRB Energy
VRB’s current commercial platform is the Third Generation Vanadium Redox Energy Storage System (“Gen3 VRB-ESS®”). The Gen3 VRB-ESS is a commercially validated system that presents a superior solution for grid-scale utility storage compared to existing lithium-ion batteries. VRB-ESS® deliver better levelized cost of storage with superior safety characteristics compared to lithium-ion battery systems, and we believe that the Gen3 VRB-ESS platform is presently the largest and most efficient in the market. In 2023 VRB’s 1MW power module and 60kW cell stacks were certified to Underwriters Laboratories (“UL”) UL1973 product safety standards. UL 1973 is recognized as a global standard for commercially available battery energy storage.
We believe that a vertically integrated vanadium flow battery business will round out the Company’s electrification transition portfolio and provides us with additional growth opportunities in what management considers a rapidly growing end-user market. Growing needs for renewable energy sources are expected to drive the demand for longer-lasting, safe and reliable high-performance vanadium flow batteries. VRB’s core technology is VRB-ESS®, engineered for low-cost manufacturing, optimal performance, and long-life. While lithium-ion batteries are well suited to power consumer electronics and electric vehicles, their battery lifetime is limited and would have to be replaced periodically throughout a grid-scale project’s lifetime.
We believe VRB-ESS® can be charged and discharged over an almost unlimited number of cycles without wearing out, providing the lowest lifecycle cost of energy of any type of battery storage. In addition, VRB’s proprietary electrolyte formula contains no heavy metals and the liquid electrolyte is non-toxic, non-flammable and 100% reusable, making VRB-ESS® superior to lithium-ion batteries for grid scale energy storage.
Vanadium pentoxide (“V 2 O 5 ”) is a key input factor and cost driver of VRB-ESS®. As part of its strategic business plan, VRB has been working on vertically integrating into V 2 O 5 production through recycling of vanadium-bearing waste products, principally produced by petroleum refineries. In 2020, VRB established a joint venture with Yang Xing Vanadium (“YX”) to operate a 1,800 tpa V 2 O 5 plant in Vietnam, which agreement terminated in May 2022. This allowed VRB to secure an initial low-cost supply of V 2 O 5 for battery production and realize revenues from the sale of a portion of the vanadium produced.
