Property
Description and Location
The
Elk Creek Property is a carbonatite deposit located in Johnson County, southeast Nebraska, USA. The carbonatite contains elements
of economic significance, including niobium, titanium, and scandium, as well as potential economic significance for rare earth
products. The Elk Creek Property is situated as shown below and is located within the USGS Tecumseh Quadrangle Nebraska SE (7.5
minute series) mapsheet in Sections 1-6, 9-11; Township 3N; Range 11E and Sections 19-23, 25-36; Township 4N, Range 11E, at approximately
40°16’ north and 96°11’ west in the State of Nebraska, in central USA. The Elk Creek Property is approximately
45 miles southeast of Lincoln, Nebraska, the state capital of Nebraska.

Title
and Ownership
Land
in the project area is exclusively owned by private entities, and there is no federal or state land in the project area. The Company
has secured its rights to the project area by purchasing land from private landowners or by entering into agreements with the
landowners as described below.
The
Company currently owns approximately 227 acres of land and associated mineral rights, and an additional 80 acres of surface rights
and 40 acres of mineral rights, all within the carbonatite footprint. The Elk Creek Project’s mine infrastructure and a
portion of the supporting operations is planned to be located on this land. Ownership of the mineral rights discussed above includes
a 2% NSR royalty and grants us access to more than 90% of the Elk Creek Project’s mineral resources and mineral reserves.
As
of June 30, 2025, the total book value of the Elk Creek Property and associated buildings and equipment was $16.9 million.
On
August 1, 2025, ECRC closed on its option to purchase three parcels of land in the project area, consisting of the property known
as Woltemath80S and approximately 1.66 acres of the property known as Woltemath002, for an aggregate purchase price of approximately
$2.7 million, pursuant to the terms of two OTPs.
The
Company currently holds six OTPs that are associated with the Elk Creek Project and one perpetual easement on a land parcel adjacent
to the Missouri River. The current optioned land package covers an area of 1,272 acres and is reflective of the land needed to
secure the remaining mineral resources and mineral reserves held under the OTPs along with the land needed for the development
and operations of the Elk Creek Project for its proposed 38-year operating life.
In
general, exercise of an OTP is accomplished by paying the greater of a fixed amount per acre or a multiple of the appraised value
at the time of purchase. If the land is not purchased by the Company during the term of the OTP and the land in question is needed
for the project, the Company intends to negotiate a new OTP with the landowner. The OTP is accompanied by a negotiated payment
to the landowner that is paid upon execution of the OTP by the Company and the landowner. As of June 30, 2025, the Company was
obligated to make payments totaling approximately $101,000 over the next 15 years to maintain our rights under these OTPs. Details
on the current OTPs held by the Company are shown in the table below.

The
OTPs are between NioCorp’s subsidiary ECRC and the individual landowners. Land subject to the OTP agreements is currently
used for agricultural purposes, including growing row crops (corn and soybeans) and pasturing livestock. The land owned by ECRC
houses the Company’s drill core inventory and geological sample repository in two steel core shed buildings and the Company
maintains a cover crop (sorghum and rye) on portions of the property that were formerly used for growing row crops. The former
landowner maintains a residence and several outbuildings on the property subject to a life estate that accompanied the purchase
of the property by the Company in fiscal year 2021.
The
agreements that involve mineral rights include a 2% NSR royalty attached with the OTP. The OTPs grant the Company an exclusive
right to explore and evaluate the property for the term thereof, with an option to purchase the surface rights or a combination
of the mineral and surface rights at any time during the term. As the Woltemath80S agreement was limited to an option to purchase
the surface rights only, it does not contain an NSR provision.
Land
Tenure Map as of September 2025
The
current estimated mineral resource and reserve is wholly contained within land owned by the Company and parcel Woltemath003J.
The Company considers these two properties to be the only properties on which the Company’s development of the Elk Creek
Project is substantially dependent.
As
part of the OTPs, where required, the Company has also secured surface rights, which allow for access to the land for drilling
activities and associated mineral exploration and project development work.
27
Accessibility,
Physiography, Climate and Infrastructure
The
Elk Creek Property is easily accessible year-round as it is situated approximately 45 miles southeast of Lincoln, Nebraska, the
state capital, and approximately 68 miles south of Omaha, Nebraska. Access to the site can be completed via road or from one of
the regional airports. There are several regular flights to both Lincoln and Omaha; however, the Elk Creek Property is most easily
accessible from Lincoln. From Lincoln Municipal Airport, the Elk Creek Property is accessed via paved roads on the main network
and a secondary network of gravel roads. The drive from the Lincoln Municipal Airport to the property is typically 1 hour and
15 minutes, and from Omaha’s Eppley Airport, the drive is approximately 1 hour and 45 minutes.
The
Elk Creek Property is immediately adjacent to paved Nebraska state highway 50, and the mineral resource and mineral reserve are
centered in Township 4N, Range 11E, Section 33. This section is immediately southwest of the junction of Nebraska state highways
50 and 62. Rail access is available in the town of Elk Creek, which is located 3 miles east of the project area. Water is available
at the project site from a well, as well as from Elk Creek, which crosses Section 33. Water is also available from the Johnson
County Rural Water system, which has distribution infrastructure on the north side of the Section 33 and from the Pawnee County
Rural Water system, which has distribution infrastructure on the south side of Section 33. Electricity is provided at the Company’s
Core Storage sheds located on the west side of Section 33 on land owned by the Company from the Omaha Public Power District (“OPPD”).
Personnel are available from the local surrounding towns, including Elk Creek (3 miles east), Tecumseh (6 miles north), Steinauer
(5 miles south), Pawnee City (10 miles south) and Syracuse (27 miles north). Due to the project’s location in Nebraska,
there are no ports nearby.
Southeast
Nebraska is situated in a humid continental climate (Dfa) on the Köppen climate classification system. In eastern Nebraska,
this climate is generally characterized by hot humid summers and cold winters. Average winter temperatures vary between 13°F
to 35°F. Average summer temperatures vary between 64°F to 90°F. Exploration, construction and operational activities
may be conducted all year round.
Average
monthly precipitation (rain and snowfall) varies between 0.9 and 5.0 inches. Average yearly precipitation is between 31 and 33
inches with an average yearly snowfall of approximately 28 inches. Nebraska is located within an area known for tornadoes which
runs through the central U.S. where thunderstorms are common in the spring and summer months. Tornadoes primarily occur during
the spring and summer and may occur into the autumn months.
There
are several local communities near the Elk Creek Property, including Elk Creek and Tecumseh, that will provide local housing for
the Elk Creek Project. There are a number of other communities within driving distance and the large cities of Lincoln and Omaha
are within reasonable driving distance. Mining activities currently taking place in the area are limited to limestone and aggregate
operations to support the local cement manufacturing and construction industries.
The
Elk Creek Project is expected to incorporate surface and underground infrastructure, as well as tailings storage facilities. The
offsite infrastructure is expected to include a new high voltage transmission line constructed by the local utility company and
providing power to an on-site primary sub-station and a natural gas pipeline built by the owner of the interstate pipeline. Water
used for all on-site process needs and activities will be supplied from mine dewatering activities, local groundwater wells and
from a local water utility. See “ 2022 Elk Creek Feasibility Study ” below for additional information regarding
proposed infrastructure related to the Elk Creek Project.
The
local topography of eastern Nebraska is relatively low-relief with shallow rolling hills intersected by shallow river valleys.
Elevation varies from about 1,066 to 1,280 ft above sea level. Bedrock outcrop exposure is nonexistent in the Elk Creek Project
area.
The
majority of the area around the Elk Creek Project is used for cultivation of corn and soybeans, along with uses as grazing land.
Native vegetation typical of eastern Nebraska is upland tall-grass, prairie and upland deciduous forests.
28
Geology
and Mineralization
Geology
The
Elk Creek Property includes a carbonatite that has intruded older Precambrian granitic and low- to medium-grade metamorphic basement
rocks. The carbonatite is an elliptical magmatic body with a northwest-trending long axis perpendicular to the strike of the Midcontinent
Rift System, near the northern part of the Nemaha uplift. The carbonatite consists predominantly of dolomite, calcite and ankerite,
with lesser chlorite, barite, phlogopite, pyrochlore, serpentine, fluorite, sulfides, bastnasite, monazite, and quartz. It is,
however, believed from stratigraphic reconstruction based on drill core observation in the area that the carbonatite is unconformably
overlain by approximately 200 m of essentially flat-lying Palaeozoic marine sedimentary rocks, including carbonates, sandstones
and shales of Pennsylvanian age.
Mineralization
The
property hosts niobium, titanium, and scandium mineralization as well as REE mineralization that occurs within the Elk Creek carbonatite.
The current known extents of the carbonatite unit are approximately 950 m along strike, 300 m wide, and 750 m in dip extent, below
the unconformity. Niobium, titanium, scandium, and rare earths are considered the main elements of interest.
The
deposit contains significant concentrations of niobium. Based on the metallurgical testwork completed to date at a number of laboratories
using QEMSCAN® analysis, the niobium mineralization is known to be fine grained, and that 77% of the niobium occurs in the
mineral pyrochlore, while the balance occurs in an iron-titanium-niobium oxide mineral of varying composition.
Within
the Elk Creek carbonatite, a host of other elements exist with varying degrees of concentration. The Company has completed both
whole rock analysis and multi-element analysis on all samples for the 2014 drilling program, described below, plus resampling
of selected historical core/pulps between 2011 and 2014.
Historical
Exploration
Drilling
at the Elk Creek Property was conducted in three phases. The first was during the 1970’s and 1980’s by the Molybdenum
Company of America (“Molycorp”), the second in 2011 by Quantum Rare Earth Developments Corp (“Quantum”
- NioCorp under its former name), and the third and latest program from 2014 to 2016 by NioCorp. To date, 129 diamond core holes
have been completed for a total of 64,981 m over the entire geological complex. Of these, a total of 48 holes (33,909 m) have
been completed to date in the mineralized area and are used in the current mineral resource and reserve estimates. Five additional
holes, with a total length of 3,353.1 m, were drilled for hydrogeologic and geotechnical purposes in 2015. No sampling has been
completed of these five holes to date and therefore they have not been considered for the mineral resource or reserve estimates.
All
drilling has been completed using a combination of Tricone, Reverse Circulation (“RC”) or Diamond Drilling (“DDH”)
in the upper portion of the hole within the Pennsylvanian sediments. All drilling within the underlying carbonatite has been completed
using DDH methods.

Molycorp,
1973-1986
Between
1973 and 1974, Molycorp completed six drillholes: EC-1 to EC-4, targeting the Elk Creek anomaly, and two other holes outside the
Elk Creek anomaly area. Drillholes were typically carried out by RC drilling through the overlying sedimentary rocks and diamond
drilling through the Ordovician-Cambrian basement rocks.
Molycorp
continued their drill program from 1977 and, in May 1978, Molycorp made its discovery of the current mineral resource with drillhole
EC-11. EC-11 is located on Section 33, Township 4N, and Range 11. The carbonatite hosting the Elk Creek Project was intersected
at a vertical depth of 203.61 m (668 ft).
Molycorp
continued its drilling program through to 1984, which mainly centered on the Elk Creek Project within a radius of roughly 2 km.
By 1984, Molycorp had completed 57 drillholes within the Elk Creek gravity anomaly area, which included 25 drillholes over the
Elk Creek Project area.
From
1984 to 1986, drilling was focused on the Elk Creek gravity anomaly area. The anomaly area is roughly 7 km in diameter and drilling
was conducted on a grid pattern of approximately 610 m by 610 m (roughly 2,000 ft by 2,000 ft) with some closer spaced drillholes
in selected areas.
By
1986, a total of 106 regional drillholes were completed for a total of approximately 46,797 m (153,532 ft). The deepest hole reached
a depth of 1,038 m (3,406 ft) and bottomed in carbonatite.
Quantum, 2011
In
April 2011, Quantum conducted a preliminary drill program (three holes) on the Elk Creek deposit and two REE exploration targets
(two holes), which have been excluded from the current mineral resource and reserve estimation, as they do not intersect the Nb 2 O 5 anomaly
and are located to the east. The objectives of the drill program over the Elk Creek Property were to verify the presence of higher-grade
niobium mineralization at depth, and to infill drill the known niobium deposit in order to upgrade the resource category of the
previous resource estimate and expand the known resource. The drill program was also established to collect sufficient sample
material for metallurgical characterization and process development studies of the niobium mineralization.
The
2011 program consisted of five inclined drillholes, totaling 3,420 m of NQ size diameter core. Inclusive of this total, three
drillholes, totaling 2,318 m, were drilled into the known Elk Creek deposit.
NioCorp,
2014 to Present
NioCorp
commenced drilling on the Elk Creek Property using a three-phased program. The three-phased program was originally based on 14
drillholes for approximately 12,150 m (announced in a press release on April 29, 2014), but was subsequently expanded during the
program to 18 drillholes for approximately 15,482 m. Three of the 18 drillholes were drilled for the purpose of metallurgical
characterization and process development studies. Two of these drillholes, NEC14-MET-01 and NEC14-MET-02, were not assayed, while
NEC14-MET-03 was quarter cored with one quarter being assayed and the remainder used for metallurgical testwork. The drilling
has been orientated to intersect the geological model from the southwest and northeast (perpendicular to the strike), with the
exception of NEC14-011 and NEC14-012, which were oriented southeast and northwest, respectively.
During
fiscal year 2022, NioCorp collected a total of 1,095 samples originating from 18 diamond drill holes completed by MolyCorp, as
discussed above. These samples were collected, and subsequently assayed, in order to fill in gaps in our records regarding REE
grades and tonnage that may exist in the deposit. Assaying was conducted at Actlabs in Ancaster, Ontario. The assay results were
subjected to a Quality Assurance and Quality Control (“QA/QC”) program consistent with industry best practices.
Internal
Controls
NioCorp
integrated a series of routine QA/QC procedures throughout the sampling and analysis portion of the drilling programs to ensure
the highest level of quality was maintained throughout the process leading to the estimate of mineral reserves and mineral resources
for the Elk Creek Project. This included the insertion of duplicate samples taken from various stages of the process, insertion
of known control samples (standard reference materials, certified reference materials (“CRM”), and blanks) and sending
third-party pulps to a secondary lab (SGS Canada Inc.).
30
Sample
tickets were assigned initially at the core shed using barcodes with duplicate tickets placed inside and on the outside of the
bag. Sample identification was confirmed using barcode labelling and visual sample type comparisons before sample shipment. The
use of barcoded samples ensured both shipment forms and analytical labs used accurate information. Multiple types of QC samples
were inserted at this stage of the process, which includes the following:
● Field
quartz blanks (1 in 20, or 5%) were inserted within or immediately after samples collected
from mineralized intervals, targeting zones of elevated visual mineralization, where
possible.
● CRMs
(1 in 20, or 5%) were inserted in the field with the sample sequence.
● Field
quarter-core duplicates (1 in 20, or 5%) were inserted to test mineralization and sampling
variability.
Additional
details on the QA/QC program can be found in Section 8 of the S-K 1300 Elk Creek Technical Report Summary.
Mineral
deposits, including the Elk Creek deposit, are inherently uncertain because of variability at all scales and sparse sampling.
In addition to uncertainty associated with estimation, there are specific risks and sources of uncertainty associated with the
Elk Creek deposit. See Item 1A., Risk Factors.
S-K
1300 and other similarly purposed International Codes (JORC, 2012; NI 43-101, 2014) are designed to require disclosure to the
public of risks relating to mineral resource and reserve estimation as identified and evaluated by a qualified person. The qualified
persons responsible for the S-K 1300 Elk Creek Technical Report Summary address the technical risks in various sections and consider
that no material technical risks are identified. Additional descriptions of the risks and uncertainty associated with reported
mineral reserves and resources can be found in Section 11 of the S-K 1300 Elk Creek Technical Report Summary.
2022
Elk Creek Feasibility Study
During
fiscal year 2022, the Company launched geological, metallurgical, engineering, and other analyses to assess the feasibility of
adding REE production to its plans once sufficient work has been completed. The Company and its consultants were required to complete
additional assays of historical drill core to fill data gaps in the existing resource database to establish an REE mineral resource.
The mine plan was also updated and the S-K 1300 Elk Creek Technical Report Summary was filed with the SEC as an exhibit to the
Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2022. The S-K 1300 Elk Creek Technical Report Summary
was based on the economic and process results of the feasibility study conducted by the qualified persons, which were also presented
in the 2022 NI 43-101 Elk Creek Technical Report.
The
Elk Creek Project is planned as an underground mining operation using a long-hole stoping mining method and paste backfill, operating
with a processing rate of 2,764 tonnes per day. Expected total production over the 38-year mine life includes 171,140 tonnes of
payable niobium, 3,676 tonnes of Sc 2 O 3 , and 431,793 tonnes of TiO 2 . Estimated up-front direct
capital costs are $760 million, in addition to indirect costs of $187 million, pre-production capital costs of $92 million, an
overall contingency of $102 million, and pre-production net revenue credit of $257 million.
Financial
Analysis Included in the 2022 Elk Creek Feasibility Study
The
metrics reported in the S-K 1300 Elk Creek Technical Report Summary are based on the cash flow model results. The metrics are
on both a pre-tax and after-tax basis, on a 100% equity basis with no Elk Creek Project financing inputs and are in first quarter
2019 U.S. constant dollars. Foreign exchange impacts were deemed negligible as most, if not all, costs and revenues are denominated
in U.S. dollars. Key criteria used in the analysis are discussed in detail throughout this section.

Planned
Mining Operations
The
Elk Creek Project is planned as an underground mining operation using a long-hole stoping mining method and paste backfill, with
shaft access to minimize development through water bearing horizons. The mine will utilize jumbo drills for lateral development
and tophammer and down-the-hole drills for vertical development and production stoping. Rock bolters will be used for ground support
and probe holes will be used to support mine grouting where required. Ore will be remotely mucked from the bottom stope accesses
using 14 tonne Load-Haul-Dump units (“LHD”). The LHDs will transport the ore to an ore pass directly or to remuck
bays to maximize the efficiency of the stope mucking operations. When needed, a second LHD and a fleet of 40 tonne haul trucks
will be used to transport ore from the remuck bays to the grizzly feeding the underground material handling system. Multiple remuck
bays are used on each level to avoid interference between the LHD and the haul trucks. The ore is fed through the grizzlys with
rock breakers into an underground crusher (the “Primary Crusher”) and via a material handling system to the surface.
Planned
Processing Operations
Planned
ore process operations include mineral processing, hydrometallurgical processing (“Hydromet”), and pyrometallurgical
processing (“Pyromet”) housed in separate buildings.
The
mineral processing building will house all of its equipment within a single large building. Ore from the Primary Crusher (located
in the underground mine) will be fed to the secondary cone crusher system, operating in closed circuit with a double deck screen.
The screen undersize from the cone crusher system will be fed to a high-pressure grinding roll unit (“HPGR”), operating
in closed circuit with another double deck screen. The HPGR screen undersize is the comminution product that will report to the
Hydromet process.
The
Hydromet plant building will be a multi-level engineered steel structure, which will house equipment on two levels. Ore from mineral
processing will be fed through 15 individual processes required to separate the three recoverable products. The purpose of the
Hydromet processing steps is to leach the pay metals into solution using two separate acid leaches (Hydrochloric Acid Leach and
Sulfuric Acid Bake), remove impurities, separate the three pay metals, and perform precipitation/processing to final solid oxide
forms. Outputs from the Hydromet process include saleable TiO 2 and Sc 2 O 3 , with Nb 2 O 5
reporting to the Pyromet plant for final processing. The Hydromet plant will be supported by a Hydrochloric Acid Regeneration
plant and a Sulfuric Acid Plant.
The
Pyromet building will house most of its equipment within a single building. The purpose of the Pyromet plant is to reduce the
Nb 2 O 5 coming from the Hydromet plant by converting it into a saleable FeNb metal. Aluminum shots and iron
oxide pellets will be introduced to an electric arc furnace on a continuous basis along with fluxing agents and Nb 2 O 5
to produce a saleable ferroniobium metal.
Proposed
Production Plan and Schedule
Based
on the 2022 Elk Creek Feasibility Study, the operating mine life is approximately 38 years with a nominal processing rate of 2,764
tonnes per day. The Elk Creek Project timeline is based on 39 months to mechanical
34
completion after Authorization to Proceed,
plus an additional six months of commissioning and ramp-up to 100% of production capacity for a total of 45 months and assumes
no financing constraints. The Board must approve a construction program and budget before construction of the Elk Creek Project
can begin. This approval, along with the receipt of all required governmental permits and approvals and the completion of project
financings, will determine whether and when construction of the Elk Creek Project can begin.
Proposed
Tailings Storage
The
tailings produced by the process plant will consist of filtered water leach residue, calcined excess oxide, and slag. Four engineered
and lined tailings storage facilities (“TSFs”) will be constructed sequentially to contain the tailings over the life
of the Elk Creek Project and would contain approximately 14.5 million tonnes of tailings. The tailings facilities have been
designed to incorporate two independent areas: a composite-lined tailings solids storage area; and an area with double lined containment,
including a leak collection and recovery system for management of stormwater runoff and drainage from the tailings solids. The
TSFs will store predominantly dry (i.e., not in a slurry consistency) tailings from the plant with embankment construction based
on a “downstream” construction method. Facility closure is considered in the design.
Proposed
Salt Management
The
crystalline salt produced as a waste product of heating and evaporating brine from the reverse osmosis (“RO”) water
treatment plant will be transported by conveyor to the temporary salt staging area and then be transported by truck to the dedicated
salt management cells (“SMC”). Two SMCs will be constructed sequentially to contain the salt over the life of the
project and would contain approximately 1.63 million cubic meters of salt. The SMCs design will incorporate a composite-lined
storage area with double-lined containment including a leak collection and recovery system for management of stormwater runoff
and drainage.
Proposed
Water Management
For
the first several years of construction, the advancement of the shaft and underground workings will require limited dewatering,
anticipated to be through lower-level sumping and pumping for surface collection and disposal. Initially, water will be stored
in the lined SMC #1 during construction or will be trucked off-site for treatment at a local publicly owned treatment works. Excess
water in the SMCs will be spray evaporated within the footprint of the SMC, to avoid the reintroduction of soluble salts into
the water treatment system. Temporary on-site storage or off-site shipment and disposal of the crystallizer solid waste may be
necessary until construction of SMC #1 is completed.
Once
full operations commence, we anticipate a shortfall of approximately 3,700 gallons per minute of operational and processing water,
as the underground mine dewatering is only expected to produce 1,000 gallons per minute. To make up this shortfall, we would purchase
fresh water from a local utility and from local landowners.
Once
tailings begin being deposited in the TSF, internal contact water (from residual moisture in the tailings and precipitation falling
within the impoundment footprint) will need to be actively managed. This water will be collected and treated using lime softening
to precipitate hydroxide and carbonate solid forms for many of the inorganic constituents. The treated water will be filtered
to remove the solids (which will be returned to the TSF for disposal), and the clean water will be pumped to the process plant
RO system for further treatment. The clean water from the process plant RO unit will be used in the process plant, and the reject
concentrate will be crystallized and deposited into the SMCs.
Proposed
Source of Power
The
local power utility (Omaha Public Power District) will provide power from nearby transmission lines to the site. This will require
that an approximate 18-mile transmission line be installed by the utility to provide the site sub-station with the required site
power demand. The local power utility will also design and install the main substation that will be owned and maintained by the
utility. This infrastructure will be paid back through rate charges on the electrical usage.
35
Proposed
Source of Natural Gas
Natural
gas, to be used throughout the Elk Creek Project during the construction and operation phases of the project, will be brought
to the site via pipeline from the local utility company. NioCorp has a natural gas transportation contract with Tallgrass Energy,
which operates the Rockies Express (“REX”) pipeline. Tallgrass will construct a 45 kilometer (28 mile) gas pipeline
lateral from the main REX pipeline system in Kansas to the project site. The lateral will be sized to provide a minimum of 27.5
dekatherms of gas per day. Natural gas will be distributed to all on-site facilities utilizing buried high-density polyethylene
natural gas distribution pipe. Natural gas piping above ground and located inside of facilities will consist predominately of
carbon steel pipe. Maximum on-site pipeline distribution pressure will be 100 pounds per square inch gauge. Natural gas will be
used for facility heating, water heating, and for gas-fired process equipment.
Markets
Market
studies for niobium, TiO 2 , and Sc 2 O 3 are an important part of the proposed Elk Creek operation.
These commodities, especially niobium and Sc 2 O 3 , are thinly traded without an established publicly available
price discovery mechanism. Hence, detailed third-party market studies provide the basis for assumptions used in the economic analysis.
The
economic analysis in the 2022 Elk Creek Feasibility Study used the 2019 U.S. dollar base price of $47/kg Nb as the forward-looking
price for steel grade (65%) ferroniobium based on published independent third-party reports. The base price is adjusted to a realized
price to account for the discount provisions contained in the two ferroniobium offtake agreements that the Company has concluded.
NioCorp
engaged OnG Commodities LLC (“OnG”) to produce a market assessment in April 2017. The study examines current scandium
production trends (approximately 20 tons/year) from existing and emerging producers plus an outlook for supply to 2028. The
outlook then reviewed the current and emerging applications for scandium, including fuel cells, aerospace, industrial and other
uses, plus an outlook for demand to 2028. Based on these inputs, OnG provided pricing forecasts and global demand volumes by year
to 2028 based estimated production costs and supply-demand balances. The pricing for the OnG Commodities report was updated for
NioCorp in 2019.
No
formal market study was done for TiO 2 as it only represents 2% of overall revenue in the economic analysis. All market
information for titanium and TiO 2 is derived from USGS Commodity Market Summaries (Bedinger, 2019).
Taxation
Rates Included in the 2022 Elk Creek Feasibility Study
Taxes
that may be levied on the Elk Creek Project include corporate income tax rates of 21% for federal and 5.84% for Nebraska. The
Elk Creek Project is eligible for federal depletion allowances and credits, as well as various state incentives. The calculated
effective income tax rate for the Elk Creek Project is 16.42% for the 2022 Feasibility Study.
Design
Considerations for Environmental Performance
The
current mine design incorporates the following strategies and technologies designed to minimize environmental impacts of operation:
● Zero
Process Liquid Discharge: The Elk Creek facility will now operate as a “Zero Process
Liquid Discharge” facility, with no releases of process liquids. Instead, both
naturally occurring, brackish (slightly salty) water produced during mining operations,
and water used in ore processing, will be treated on site for use in operations. A solid
salt will be produced from water treatment operations which will be stored on site.
● Additional
Protection of Groundwater Resources Through Artificial Ground Freezing: The Elk Creek
Project’s new mine design will utilize artificial ground freezing as part of the
process of sinking the production and ventilation shafts. Artificial ground freezing
creates a temporary frozen barrier that helps to protect groundwater resources in the
area while shaft-sinking operations are underway.
● Avoidance
of Permanent Impacts to Federally Jurisdictional Waters: We designed the layout of the Elk Creek Project to minimize or avoid
permanent impacts to any federally jurisdictional waters and/or wetlands on the
36
property. This reduced the expected environmental impacts
and allowed the Elk Creek Project to secure a Clean Water Act Section 404 permit from
the USACE under the Nationwide Permit Program, a much more efficient and less expensive
process than an individual Section 404 permit. No other NEPA-level federal permits are
now expected to be required for the Elk Creek Project.
● Recycling
of Reagents Used in Mineral Processing: Metallurgical and process advances made in 2016
and 2017 are expected to help reduce the volume of material planned for disposal in the
Elk Creek Project’s tailings storage areas. As more of this material is recycled,
the environmental footprint of the Elk Creek Project is reduced.
● Utilizing
Tailings as Underground Mine Backfill: We plan to fill underground voids concurrently
with mining operations using a paste backfill material that contains mine waste material
that typically would be stored in above-ground tailings storage areas.
The
Company has not identified any significant encumbrances to the property it owns or holds under OTP agreements. The Company has
not had any permit violations or fines since the filing of our Annual Report on Form 10-K for the fiscal year ended June 30, 2024.
Permitting
requirements for the project have been identified. The Company holds an Air Construction Permit from the State of Nebraska and
a Special Use Permit from Johnson County, both of which are necessary to allow the start of project construction. In addition,
the Elk Creek Project will be required to obtain a series of permits for operations from federal, state, and local agencies. The
majority of these permits are ministerial in nature and present minimal risk to the Company and typically involve the completion
of an application and the payment of a nominal fee. Three permits from the state of Nebraska are discretionary in nature, where
an application and fee are provided to the state and the state must make a decision as to whether or not the permit will be granted.
While the risk involved in such permits is low, such discretionary permits require more processing time by the state and do require
the state agency to make a decision in favor of issuance of the permit. These three permits include the following:
● Solid
Waste Permit;
● Air
Operating Permit; and
● Radioactive
Materials License.
The
cost and schedule for obtaining both the discretionary and ministerial permits is included in the overall execution plan for the
Elk Creek Project. Additional details on the project’s permitting requirements can be found in Section 17 of the S-K 1300
Elk Creek Technical Report Summary.
Mineral
Reserves and Resources
The
mineral reserves and mineral resources disclosed below are based on the S-K 1300 Elk Creek Technical Report Summary, which was
originally filed as Exhibit 96.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2022. Mineral
reserves and mineral resources at the Elk Creek Project as of June 30, 2025, are summarized in the tables below. Further discussion
and background regarding the approaches used to establish mineral reserves and mineral resources is contained in Chapters 11 and
12 of the S-K 1300 Elk Creek Technical Report Summary.

● The
qualified person for the mineral reserve estimate is Optimize Group Inc. The estimate
has an effective date of June 30, 2025.
● The
mineral reserve is based on the mine design, mine plan, and cash-flow model utilizing
an average cut-off grade of 0.679% Nb 2 O 5 with an NSR of $180/mt.
● The
estimate of mineral reserves may be materially affected by metal prices, environmental,
permitting, legal, title, taxation, socio-political, marketing, infrastructure development,
or other relevant issues.
● The
economic assumptions used to define mineral reserve cut-off grade are as follows:
○ Annual
life of mine (LoM) production rate of ~7,450 tonnes of FeNb/annum during the years of
full production.
○ Initial
elevated five-year production rate ~ 7,500 tonnes of FeNb/annum when full production
is reached.
○ Mining
dilution of ~6% was applied to all stopes and development, based on 3% for the primary
stopes, 9% for the secondary stopes, and 5% for ore development.
○ Mining
recoveries of 95% were applied in longhole stopes and 62.5% in sill pillar stopes.

● Price
assumptions are as follows: FeNb $39.60/kg Nb, Sc 2 O 3 $3,675/kg,
and TiO 2 $0.88/kg. Price assumptions are based upon independent market analyses
for each product as of June 30, 2022.
39
● Price
and cost assumptions are based on the pricing of products at the “mine-gate,”
with no additional down-stream costs required. The assumed products are ferroniobium
(metallic alloy shots consisting of 65%Nb and 35% Fe), a titanium dioxide product in
powder form, and scandium trioxide in powder form.
● The
mineral reserve has an average LoM NSR of $563.06/tonne.
● Optimize
Group has provided detailed estimates of the expected costs based on the knowledge of
the style of mining (underground) and potential processing methods (by third-party qualified
persons).
● Mineral
reserve effective date is June 30, 2025. The financial model was run after the estimate
of the NSR above, which reflects a total cost per tonne of $196.72 versus $189.91. This
is not considered a material change.
● Price
variances for commodities are based on independent market studies versus earlier projected
pricing. The independent market studies do not have a negative effect on the reserve.
Comparison
of Mineral Resources and Mineral Reserves
There
were no changes in the Elk Creek Project mineral resource or reserve estimates as of June 30, 2025, as compared to the Elk Creek
Project mineral resource and reserve estimates as of June 30, 2024.
Environmental
and Social
A
number of key permits and environmental management requirements have been identified for the Elk Creek Project, some of which
need to be implemented as soon as practicable in order to maintain the proposed Elk Creek Project schedule.
● While
not necessarily complex, the timing generally required to complete permitting through
any federal regulatory agency requires that NioCorp engage key agencies (in this case
the USACE and possibly the EPA) early on in Elk Creek Project development and consider
the siting and orientation of facilities carefully to minimize the risk of a protracted
National Environmental Policy Act analysis of the Elk Creek Project. At the present time,
the Company believes that we have completed the major federal permitting actions needed
for project construction, although changes to the design or location of project facilities
may require that additional federal permits be obtained.
● Construction
at the facility requires an Air Permit from the State of Nebraska, which was issued to
the Company on June 2, 2020. The Air Permit describes all the prospective air emissions
from the facility and required the completion of an air quality model that demonstrates
compliance with the NAAQS. On April 15, 2022, the Company announced that the Nebraska
Department of Environment and Energy advised the Company that periodic extensions to
the Elk Creek Project’s Air Permit are no longer required because the Company has
met the regulatory definition of “construction, reconstruction, or modification
of the source” since the permit was issued.
● A
radioactive materials license will be needed from the Nebraska Department of Health and
Human Services (“NDHHS”), Office of Radiological Health. Because of their
limited experience with hard rock mining in the State of Nebraska, much less mining that
includes Naturally Occurring Radioactive Material, the NDHHS may require additional information
and more time to approve the Elk Creek Project under a Broad Scope License. The Company
has been working with NDHHS on this aspect of project permitting since 2014.
● Documentation
of existing baseline environmental conditions at the Elk Creek Project site was initiated
in 2014 and will continue as needed throughout the permitting process.
● Surface
water monitoring will continue throughout the permitting process and extend into construction
and operations as part of the Environmental Management System and likely State of Nebraska
permit requirements.
● A
wetland delineation and potential jurisdictional waters assessment was conducted in late
2014 to identify wetland and drainage features within the proposed Elk Creek Project
boundary which resulted in a formal JD being issued by the USACE on September 6, 2016.
● The
major land-use authorization for the project was received from Johnson County, Nebraska,
on December 24, 2019, in the form of a Special Use Permit for the project. This land-use
permit is a necessary precursor to any project-related construction activities. County
zoning permits will be required for individual buildings constructed at the site, and
the County requirement is that such applications must be submitted five days before construction
commences.
40
● Closure
costs for the Elk Creek Project have been estimated at just over $44 million, including
approximately $13.5 million for reclamation and closure of the TSFs and $16.6 million
for plant and building removal and reclamation.
● Community
engagement has occurred in parallel with Nebraska field operations and has included public
meetings, presentations to public agencies, communications with local and state politicians,
meetings with environmental groups, and one-on-one meetings with area landowners.
Other
Elk Creek Project Activities
On
October 30, 2024, the Company announced that it had completed bench-scale testwork at a demonstration-scale processing plant located
in Trois-Rivieres, Quebec built by the Company and L3 Process Development (“L3”) and operated by L3 (the “Demonstration
Plant”), that successfully demonstrated that the process developed for extracting and recovering rare earth oxides found
in the ore at the Elk Creek Project can be used to recycle the rare earth content in rare earth permanent magnets. The L3 team
was able to demagnetize and grind up permanent rare earth magnets and then leach the contained rare earth elements from the magnet.
The successful outcome of this testing opens up the possibility of accepting mixed rare earth concentrate from other mines into
the planned Elk Creek plant once it is constructed and operating to supplement the ore expected to be produced from the Elk Creek
mine.
On April 23, 2025,
the Company announced the launch of a drilling campaign (the “Campaign”) designed to support the conversion of a portion
of its current Indicated Resources into Measured Resources and the subsequent conversion of a portion of its current Probable Mineral
Reserves into Proven Mineral Reserves at the Elk Creek Project. On August 12, 2025, the Company announced the successful completion
of the Campaign. The Campaign was inclusive of nine HQ diamond drillholes, totaling 6,817 meters of drilling. Core processing is
currently underway with samples being sent to SGS USA for sample preparation and analysis. The Campaign supplemented previous exploratory
drilling and operated under existing permits issued by the State of Nebraska. The Campaign was designed to complement other technical
and economic analyses necessary to update the feasibility study for the Elk Creek Project. An updated feasibility study is necessary
as part of the due diligence process for up to $800 million in potential debt financing that NioCorp is seeking from EXIM, as further
discussed under “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity
and Capital Resources ” below.
As
a result of favorable outcomes from the Campaign in terms of schedule and budget, the Company has elected to add up to an additional
six drillholes, totaling approximately 3,930 meters, which will form Phase II of the Campaign (“Phase II”). Phase
II is designed to support the conversion of additional indicated resources into measured resources and the subsequent conversion
of additional probable mineral reserves into proven mineral reserves, as well as capturing additional hydrogeologic and geomechanical
data that will be used to continue derisking the underground mine design.
Proposed
Activities
At
present, the Company is maintaining the Elk Creek Property in anticipation of obtaining project financing that will facilitate
the construction, commissioning, and operation of the Elk Creek Project. The property is characterized as a development stage
property and is expected to move to a production stage property should financing be obtained.
As
funds become available through the Company’s fundraising efforts, we expect to undertake the following activities:
●
Continuation
of the Company’s efforts to secure federal, state and local operating permits;
●
Continued
evaluation of the potential to produce rare earth products and sell such products under offtake agreements;
●
Negotiation
and completion of offtake agreements for the remaining uncommitted production of Nb, Sc, and Ti from the project, including
the potential sale of Ti as titanium tetrachloride, as well as potential REE production;
●
Negotiation
and completion of engineering, procurement, and construction agreements;
●
Completion
of the final detailed engineering for the underground portion of the Elk Creek Project;
●
Initiation
and completion of the final detailed engineering for surface project facilities;
41
●
Construction
of natural gas and electrical infrastructure under existing agreements to serve the Elk Creek Project site;
●
Completion
of water supply agreements and related infrastructure to deliver fresh water to the project site;
●
Initiation
of revised mine groundwater investigation and control activities;
●
Based on the results
of the Company’s Demonstration Plant operations, update the characterization and testing of waste materials to support
tailings impoundment and paste backfill plant designs;
●
Initiation of long-lead
equipment procurement activities; and
●
Initiation of initial
construction work at the project site.
Non-GAAP
Financial Performance Measures
Non-GAAP
financial performance measures are intended to provide additional information only and do not have any standard meaning prescribed
by U.S. GAAP. These measures should not be considered in isolation or as a substitute for performance measures prepared in accordance
with U.S. GAAP.
The
S-K 1300 Elk Creek Technical Report Summary uses non-GAAP financial performance measures, such as EBITDA, Averaged Annual EBITDA,
and Averaged EBITDA Margin, for purposes of projecting the economic results of the Elk Creek Project. We are unable to provide
a reconciliation of these forward-looking non-GAAP measures to the most comparable U.S. GAAP financial performance measures because
certain information needed to reconcile those non-GAAP measures to the most comparable U.S. GAAP financial performance measures
is dependent on future events, some of which are outside the control of the Company, such as FeNb, Sc 2 O 3,
and TiO 2 prices, interest rates, and exchange rates. Moreover, estimating such U.S. GAAP measures with the required
precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable
effort.
