General
At July 31, 2021, we held mineral rights in uranium projects located in the U.S. States of Arizona, Colorado, New Mexico, Texas and Wyoming, in Canada and in the Republic of Paraguay by way of federal mining claims, state and private mineral leases and mineral concessions. We also held a wholly-owned uranium processing facility located in the State of Texas, our Hobson Processing Facility, which processes material extracted from our Palangana Mine.
We have prepared and will continue to prepare, from time to time, various technical reports (each, a “Technical Report”), in accordance with the provisions and requirements of National Instrument 43-101 Standards of Disclosure for Mineral Properties (“NI 43-101”), of the Canadian Securities Administrators (the “CSA”), respecting various of our mineral projects. Each of our Technical Reports have been and will continue to be filed by us on the public disclosure website of the CSA at www.sedar.com (“SEDAR”) as required by NI 43-101 and its companion policy and form. As also required by NI 43-101, each Technical Report is prepared by and authored by a qualified person as defined under NI 43-101.
22
As set forth and required by NI 43-101, each Technical Report may contain certain disclosure relating to mineral resource estimates and/or an exploration target for a subject mineral project. Such mineral resources, if any, have and will have been estimated in accordance with the definition standards on mineral resources of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101. Inferred mineral resources and exploration targets, while recognized and required by Canadian regulations, are not defined terms under the SEC’s Industry Guide 7, and are normally not permitted to be used in reports and registration statements filed with the SEC. Accordingly, we have not and will not report them in this Annual Report or otherwise in the United States. Investors are cautioned not to assume that any part or all of the mineral resources in these categories will ever be converted into mineral reserves. These amounts have great uncertainty as to their existence and to their economic and legal feasibility. In particular, it should be noted that mineral resources, which are not mineral reserves, do not have demonstrated economic viability. It cannot be assumed that all or any part of measured mineral resources, indicated mineral resources or inferred mineral resources discussed in a Technical Report will ever be upgraded to a higher category. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. Investors are cautioned not to assume that any part of the reported inferred mineral resources referred to in a Technical Report are economically or legally mineable. Exploration targets have a greater amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. In particular, it should be noted that exploration targets do not have demonstrated economic viability. It cannot be assumed that all or any part of the exploration target discussed in a Technical Report will ever be upgraded to a higher category, or if additional exploration will result in discovery of an economic mineral resource on the property.
We have not established proven or probable reserves, as defined by the SEC under Industry Guide 7, through the completion of a “final” or “bankable” feasibility study for any of our mineral projects, including our Palangana Mine. Furthermore, we have no plans to establish proven or probable reserves for any of our mineral projects for which we plan on utilizing ISR mining, such as the Palangana Mine.
On October 31, 2018, the SEC adopted the Modernization of Property Disclosures for Mining Registrants (again, the “New Rule”), introducing significant changes to the existing mining disclosure framework to better align it with international industry and regulatory practice, including NI 43-101. The New Rule became effective as of February 25, 2019, and issuers are required to comply with the New Rule as of the annual report for their first fiscal year beginning on or after January 1, 2021, and earlier in certain circumstances. The Company does not anticipate needing to comply with the New Rule until the filing of our annual report for the fiscal year ending July 31, 2022 and, at this time, the Company does not know the full effect of the New Rule on its mineral resources and, therefore, the disclosure related to the Company’s mineral resources may be significantly different when computed using the requirements set forth in the New Rule.

Texas Processing Facility and Projects
The following map shows the location of our Hobson Processing Facility and main projects in Texas:
Hobson Processing Facility
Property Description and Location
The Hobson Processing Facility is a fully-licensed and permitted in-situ recovery or ISR uranium processing plant designed to process uranium-loaded resins from satellite ISR mining facilities to the final product, U 3 O 8 or yellowcake. The Hobson Processing Facility was originally constructed in 1978 and served as a central processing site for several satellite ISR mining projects until 1996. It was completely refurbished in 2008 and, on December 18, 2009, we acquired the Hobson Processing Facility through the acquisition of STMV.
The Hobson Processing Facility is located in Karnes County, Texas, on a 7.286-acre leased tract of land, approximately one mile south of the community of Hobson and about 100 miles northwest of Corpus Christi, Texas. The surface lease of the Hobson Processing Facility is for an initial term of five years commencing May 30, 2007, and thereafter so long as uranium, thorium and other fissionable or spatially associated substances are being processed or refined without cessation of more than five consecutive years.
The Hobson Processing Facility has a physical capacity to process two million pounds of U 3 O 8 annually and is licensed to process up to one million pounds of U 3 O 8 annually, which provides for the capacity to process uranium-loaded resins from a number of satellite ISR mining facilities in South Texas. We utilize a “hub-and-spoke” strategy whereby the Hobson Processing Facility acts as our central uranium processing site (the “hub”) for our Palangana Mine and for future satellite ISR mines, including our Burke Hollow and Goliad Projects (the “spokes”), located within the South Texas Uranium Belt.
24
In January 2011, the Hobson Processing Facility began processing uranium-loaded resins received from the Palangana Mine upon commencement of uranium extraction in November 2010. Since then the Hobson Processing Facility has processed 578,000 pounds of uranium concentrates. During Fiscal 2021, the Hobson Processing facility was in a state of operational readiness.
Uranium Processing System
Once the uranium-loaded resin from the satellite ISR mining facility is delivered to the Hobson Processing Facility by semi-trailer, the material is transferred and placed in a pressure vessel for elution which involves flushing with a brine solution. The uranium is stripped from the resin in a three-stage elution process and concentrated into a rich eluate tank, at which point the solution is analyzed for total uranium concentration. After the uranium is eluted from the resin, the resin is washed to remove excess brine solution, transferred back to the trailer and returned to the satellite ISR mining facility to again begin the cycle of capturing uranium from the wellfield, transport to the Hobson Processing Facility and subsequent elution.
The uranium-rich solution remaining at the Hobson Processing Facility after elution is agitated and chemicals are added to precipitate the uranium. In this precipitation process sulfuric acid is added to reduce the pH to between 2 and 3. Hydrogen peroxide (“H 2 O 2 ”) is then added at the rate of 0.2 to 0.5 pounds of H 2 O 2 per pound of uranium while maintaining the pH of the solution between two and three using sodium hydroxide. Once the precipitation reaction is complete the solution is allowed to set in order for the uranium to precipitate and settle to the bottom of the tank. The excess overflow is decanted to a storage tank or to the waste disposal system. All waste process solutions from the plant area report to a chemical waste storage tank and waste solutions are pumped to a Class I, non-hazardous, waste disposal well system.
The remaining material, at approximately 3% to 5% solids, is pumped to a filter press where the uranium is separated from the liquid. After the uranium, or yellowcake, has been filtered, fresh water is pumped through to remove the entrained salts, with the resulting liquids pumped to the fresh eluate makeup system or the waste disposal system. From the filter press the thickened yellowcake, at 50% to 60% solids, is transferred to the drying package for drying and drumming. A zero-emissions vacuum dryer removes moisture from the yellowcake and a scrubber system removes these vapors from the dryer and discharges the gases to an exhaust stack. The dried yellowcake is packaged in 55-gallon drums. Each drum is weighed, cleaned, surveyed and analyzed, after which it is transferred to a temporary yellowcake storage area at the Hobson Processing Facility. The drums are then shipped to a third-party storage and sales facility.
25
Palangana Mine, Duval County, Texas
Property Description and Location
The Palangana Mine is located in Texas near the center of the extensive South Texas Uranium Belt. The Palangana Mine consists of multiple leases that would allow the mining of uranium by ISR methods while utilizing the land surface (with variable conditions), as needed, for mining wells and aboveground facilities for fluid processing and ore capture during the mining and groundwater restoration phases of the project. The Palangana Mine is situated in Duval County, Texas, and is located approximately 25 miles west of the town of Alice, six miles north of the town of Benavides, 15 miles southeast of the town of Freer and 12 miles southwest of the town of San Diego, as shown in the map below:
Mineral Titles
At July 31, 2021, there were seven leases covering 6,406 acres at the Palangana Mine. PAA-1 is on the de Hoyos property while PAA-2, PAA-3 and the Dome trend are on the Palangana Ranch property. Bordering the east side of the Palangana Ranch is the White Bell Ranch, which contains the Jemison Fence and Jemison East trends. The fourth major property is the Garcia/Booth property comprised of 1,278 acres which borders the east side of the De Hoyos property and contains the NE Garcia and SW Garcia trends.
Lease ownership is held by STMV, which is wholly-owned by the Company.
Accessibility, Climate, Local Resources, Infrastructure and Physiography
Topography, Elevation and Vegetation
Surface elevations at the Palangana Mine range from about 410 feet to 500 feet above sea level.
Climate and Length of Operating Season
The region’s subtropical climate allows uninterrupted, year-round mining activities. Temperatures during the summer range from 75°F to 95°F, although highs above 100°F are common, while winter temperatures range from 45°F to 65°F. Humidity is generally over 85% year-round and commonly exceeds 90% during the summer months. Average annual rainfall is 30 inches.
26
Physiography
The dome area to the west of the PAA-1 and PAA-2 deposits is a concentric collapsed area with the surrounding landscape being hilly and elevated. Surface water generally drains away from the dome area although no prominent creeks or rivers are evident.
Access to Property
The Palangana Mine occurs in the South Texas Uranium Belt between San Antonio and Corpus Christi in Duval County. Corpus Christi, the largest nearby metropolitan district, is about 65 miles to the east of the Palangana Mine. Approximately halfway between San Diego and Freer on Texas Highway 44 is a turn-off to the south, referred to as Ranch Road 3196, that runs directly through the property about eight miles from the turn-off. The road continues southward about six miles to the town of Benavides. Access is excellent, with major two-lane roads connecting the three surrounding towns and unpaved secondary roads connecting to the Palangana Mine.
Surface Rights
The uranium leaseholders under most of the current leases have conveyed the surface rights under certain conditions of remuneration. These conditions essentially require payments for surface area taken out of usage.
Local Resources and Infrastructure
An entire infrastructure is in place including office buildings, access roads, electrical power and maintenance faculties. Each property has sources of water for drilling operations for both exploration and extraction drilling.
Manpower
A nearby workforce of field technicians, welders, electricians, drillers and pipefitters exists in the local communities. The technical workforce for facility operations from the area is sparse although ample qualified resources can be found in the South Texas area from the petrochemical industry.
History prior to acquisition by our Company
Uranium mineralization was discovered during potash exploration drilling of the Palangana Dome’s gypsum-anhydrite cap rock in 1952 by Columbia Southern Inc. (“CSI”). CSI conducted active uranium exploration drilling on the property starting in March 1956. Records of CSI’s exploration work are unavailable, however, both CSI and the U.S. Atomic Energy Commission estimated underground mineable uranium mineralization. The only known details of the estimation method include a 0.15% eU 3 O 8 cut-off grade, a minimum mining thickness of three feet, and widely spaced drilling on a nominal 200-foot exploration grid. Union Carbide acquired the Palangana property in 1958 and initiated underground mine development. Development work was quickly abandoned due to heavy concentrations of H 2 S gas and Union Carbide dropped the property. Union Carbide reacquired Palangana in 1967 after recognizing that it would be amenable to exploitation by the emerging ISR mining technologies. During the 1960s and 1970s, Union Carbide drilled over 1,000 exploration and development holes and installed over 3,000 injection-extraction holes in a 31-acre lease block.
Union Carbide attempted an ISR operation from 1977 through 1979 using a push/pull injection/recovery system. Ammonia was used as the lixiviate that later caused some environmental issues with groundwater. About 340,000 pounds of U 3 O 8 were produced from portions of a 31-acre wellfield area. The extraction pounds indicated a 32% to 34% recovery rate. The push/pull injection/recovery system was later proven to be less productive than well configurations or patterns of injection wells around a recovery well. Further, the wellfield was developed without any apparent regard to the geology of the deposit including disequilibrium. The Union Carbide ISR work was basically conducted at a research level in contrast to the current level of knowledge. The historic extraction area lies on the western side of the dome.
27
In 1981 Chevron Corporation acquired the Union Carbide leases and conducted their own resource evaluation. After the price of uranium dropped to under $10 per pound, General Atomics acquired the property and dismantled the processing plant in a property-wide restoration effort. Upon formal approval of the clean up by the Texas Natural Resources Conservation Commission and the United States Nuclear Regulatory Commission, the property was returned to the landowners in the late 1990’s. In 2005, Everest Exploration Inc. acquired the Palangana property and later joint ventured with Energy Metals Corp. (“Energy Metals”) through the formation of STMV. An independent consultant, Blackstone (2005), estimated inferred resources in an area now referred to as the Dome trend proximal to the dome on the west side north of the prior Union Carbide leach field. In 2006 and 2007 Energy Metals drilled approximately 200 additional confirmation and delineation holes. The PAA-1 and PAA-2 areas were found during this drilling program. In 2008 Energy Metals was acquired by Uranium One. During 2008 and 2009 the remaining holes on this project were drilled by Uranium One. During this time the five exploration trends to the east of the dome were identified and partially delineated. In December 2009 we acquired 100% ownership of STMV.
Geological Setting
South Texas geology is characterized by an arcuate belt of Tertiary fluvial clastic units deposited along the passive North American plate. These units strike parallel to the Gulf Coast between the Mexican border and Louisiana within an area known as the Mississippi Embayment. The uranium-bearing sedimentary units are primarily of fluvial origin and were deposited by southeasterly flowing streams and rivers. Uranium deposits are contained within fault-controlled roll-fronts in the lower Pliocene-to-Miocene age Goliad Formation on the flank of the Palangana salt dome. The uranium mineralization in the Goliad Formation at Palangana occurs at a depth of approximately 220 to 600 feet below the surface.
Geological Model
Uranium mineralization in the South Texas Uranium Belt occurs as sandstone-hosted roll-front deposits. The deposits are strata-bound, elongate and often, but not necessarily, occur in the classic “C” or truncated “C” roll configuration. They can be associated with an oxidation front or can be found in a re-reduced condition where an overprint of later reduction from hydrogen sulfide or other hydrocarbon reductant has seeped along faults and fractures. The uranium bearing sandstone units can themselves be separated into several horizons by discontinuous mudstone units, and separate roll-fronts and sub-rolls can occur in the stacked sandstone sequences.
The generally accepted origin of uranium mineralization in the Goliad Formation is from leaching of intraformational tuffaceous material or erosion of older uranium-bearing strata. The leached uranium was carried by oxygenated groundwater in a hexavalent state and deposited where a suitable reductant was encountered. The oxidation/reduction (redox) fronts are often continuous for miles, although minable grade uranium mineralization is not nearly as continuous. The discontinuous nature of uranium mineralization is often characterized as “beads on a string” and is due to sinuous vertical and lateral fluvial facies changes in the permeable sandstone host horizons, coupled with ground water movements and the presence or absence of reducing material.
Figure 2: Schematic view of a typical uranium roll-front configuration.
28
The red area is the uranium mineralization deposited at the interface between the oxidized (up-gradient) sand shown in yellow and the reduced (down-gradient) sand shown in gray. The up-gradient sand has been altered by oxidizing groundwater that carried the uranium that was deposited in the roll-front at the oxidation/reduction (redox) interface. The uranium mineralization is hydrologically confined by an upper and lower confining layer of shale or mudstone. At wellfields, extraction (pumping) wells have been completed near the center of the roll-front and are fed lixiviate (leach solutions) by injection wells on each side of the front.
Mineralized Zones and Historical Drilling Results
As stated previously, mineralization does not occur in all of the Goliad sands nor does it persist in the same sand intervals across the dome area. On the west half of the dome near what is referred to as the Dome trend, Union Carbide developed the “C” sand zone. The NW Garcia and SE Garcia trends to the east of the dome also reside in the “C” sand zone. Also, to the east of the dome, the PAA-2 deposit, as well as the PAA-3 deposit, Jemison Fence and Jemison East trends all occur in the “E” sand, while the PAA-1 deposit occurs in the “G” sand. Within these mineralized horizons smaller roll-fronts are evident that can be mapped as discrete bodies. Some of these bodies contain economic mineralization while others do not. The mineralized horizons occur as stacked intervals often separated by claystones. Generally, they overlap one another but there are differences making a concurrent, multiple-horizon recovery scenario not uniformly effective.
The table below summarizes the historical drilling results at the Palangana Mine as of July 31, 2021, including drilling results prior to its acquisition by our Company on December 18, 2009.

Since commencing uranium extraction at the Palangana Mine in November 2010 to July 31, 2021, the Hobson Processing Facility has processed 578,000 pounds of uranium concentrates extracted directly from the Palangana Mine utilizing ISR methods. A summary by PAA is provided below:
●
PAA-1 commenced uranium extraction in November 2010 and remains fully-permitted. With 69 monitor wells already in place prior to our acquisition of the Palangana Mine, we drilled a total of 201 holes for well control facilities and wellfields including injection and extraction wells and infill drilling efforts. During Fiscal 2021 and the year ended July 31, 2020 (“Fiscal 2020”), no additional infill drilling took place;
●
PAA-2 commenced uranium extraction in March 2012 and remains fully-permitted. With 43 monitor wells already in place prior to our acquisition of the Palangana Mine, we drilled a total of 63 holes for well control facilities and wellfields including injection and extraction wells and infill drilling efforts. During Fiscal 2021 and Fiscal 2020, no additional infill drilling took place;
●
PAA-3 commenced uranium extraction in December 2012 and remains fully-permitted. We drilled a total of 345 holes for mineral trend exploration and delineation, monitor wells, well control facilities and wellfields including injection and extraction wells and infill drilling. During Fiscal 2021 and Fiscal 2020, no additional infill drilling took place;
●
PAA-4 permitting was completed and approved in November 2014, including the approval of the Aquifer Exemption in March 2015. The Mine Area Permit boundary was expanded to 8,722 acres from 6,200 acres to include PAA-4. Wellfield design is being finalized in preparation for installment of the first module inside PAA-4. During Fiscal 2015 we drilled five holes for a total of 214 holes for mineral trend exploration, delineation and monitor wells. All monitor wells were sampled for baseline parameters and a pumping test has been completed; and
29
●
PAA-5 and PAA-6 mine area expansion application was approved in November 2014. We drilled a total of 46 holes at PAA-5 and PAA-6 for mineral trend exploration and delineation and a monitor well. During Fiscal 2021 and Fiscal 2020, no additional drilling took place.
During Fiscal 2021 and Fiscal 2020, we reduced operations at the Palangana Mine to capture residual uranium only. As a result, no material amount of U 3 O 8 was processed at the Hobson Processing Facility.
In September 2013, we implemented a strategic plan to align our operations to a weak uranium market in a challenging post-Fukushima environment. This strategy has included the deferral of major pre-extraction expenditures and remaining in a state of operational readiness in anticipation of a recovery in uranium prices. As a consequence, U 3 O 8 pounds extracted from the Palangana Mine and processed at the Hobson Processing Facility decreased significantly during Fiscal 2015 compared to prior years, and there have been no material amount of uranium extracted from the Palangana Mine from Fiscal 2017 to Fiscal 2021.
During Fiscal 2015, the Hobson Processing Facility processed finished goods representing 18,000 pounds of U 3 O 8 (Fiscal 2014: 43,000 pounds; Fiscal 2013: 194,000 pounds; and Fiscal 2012: 198,000 pounds) extracted solely from the Palangana Mine. Based on our estimate of mineralized materials in PAA 1, 2 and 3, over which an average mining grade of 0.135% has been established, cumulative recovery since the commencement of uranium extraction in November 2010 to July 31, 2021 was 44% (July 31, 2015: 44%; July 31, 2014: 43%; July 31, 2013: 40%; and July 31, 2012: 31%).

We have not established proven or probable reserves, as defined by the SEC, through the completion of a “final” or “bankable” feasibility study for the Palangana Mine. Furthermore, we have no plans to establish proven or probable reserves for any of our uranium projects for which we plan on utilizing ISR mining, such as the Palangana Mine. Since we commenced extracting mineralized materials at the Palangana Mine without having established proven and probable reserves, any mineralized materials established or extracted from the Palangana Mine should not in any way be associated with having established or produced from proven or probable reserves.
Burke Hollow Project, Bee County, Texas
Property Description and Location
Our Burke Hollow Project is comprised of two leases covering 19,335 acres located in Texas along the eastern, down-dip side of the South Texas Uranium Belt. These leases allow for the mining of uranium by ISR methods while utilizing the land surface (with variable conditions), as needed, for mining wells and aboveground facilities for fluid processing and uranium extraction during the mining and groundwater restoration phases of the project. The Burke Hollow Project area is about 18 miles southeast of the town of Beeville, is located on the western side of US 77 and is located northeast of US 181 which links with US 59 in Beeville.
30
Virtually all mining in Texas is on private lands with leases negotiated between mining companies and each individual land/mineral owner. The Burke Hollow Project consists of two leases, one lease dated February 21, 2012, comprised of 17,510 acres, with Thomson-Barrow Corporation as mineral owner and Burke Hollow Corporation as surface owner, and the other dated December 15, 2012, comprised of 1,825 acres, with a separate owner. The leases are paid-up leases for a primary term of five years and allow for an extension term of an additional five years and so long thereafter as uranium or other leased substances are being produced. The leases have various stipulated fees for land surface alterations, such as per well or exploration hole fees (damages). The primary lease stipulation is the royalty payments as a percentage of production. Because the leases are negotiated with private land and mineral owners and none of the property is located on government land, some details of the lease information and terms are considered confidential.
There are no known environmental liabilities associated with the Burke Hollow Project. We currently have an exploration permit for work in Bee County from the RCT.
Prior to any mining activity at the Burke Hollow Project, we would be required to obtain an RML, a large area UIC Mine permit and a PAA permit for each wellfield developed for mining within the Mine Permit area. In addition, a waste disposal well would, if needed, would require a separate UIC Mine permit. These permits would be issued by Texas regulatory agencies.
The RCT requires exploration companies to obtain exploration permits before conducting drilling in any area. The permits include standards for the abandonment and remediation of test bore holes. Potential future environmental liability as a result of the mining must be addressed by the permit holder jointly with the permit granting agency. Most permits now have bonding requirements for ensuring that the restoration of groundwater, the land surface and any ancillary facility structures or equipment is properly completed. If the Burke Hollow Project reaches economic viability in the future, we would need to complete a number of required environmental baseline studies such as cultural resources (including archaeology), socioeconomic impact and soils mapping. Flora and fauna studies will need to be conducted as will background radiation surveys.
31
Accessibility, Climate, Local Resources, Infrastructure and Physiography
The Burke Hollow Project is situated in the interior portion of the Gulf Coastal Plain physiographic province. The area is characterized by rolling topography with parallel to sub-parallel ridges and valleys. There is about 47 feet of relief at the site with ground surface elevations ranging from a low of 92 feet to a high of 139 feet above mean sea level. The leased property for the Burke Hollow Project is used mostly for petroleum production, cattle ranching and game management. Access by vehicular traffic is provided from Hwy. 77 to the property.
The property is in a rural setting in southeastern Bee County. The nearest population centers are Skidmore, approximately 11 miles west, Refugio about 15 miles east, and Beeville, approximately 18 miles northwest. While Skidmore and Refugio are relatively small towns, they provide basic needs for food and lodging and some supplies. Beeville is a much larger city and provides a well-developed infrastructure that has resulted from being a regional center to support oil and gas exploration and production. The Burke Hollow Project site area has good accessibility for light to heavy equipment. There is an excellent network of county, state and federal highways that serve the region and the moderate topography with dominantly sandy, well-drained soils provide good construction conditions for building gravel site roads necessary for site access. Water supply in the project area is from private water wells, mostly tapping sands of the upper Goliad Formation. Water needs for potential future pre-extraction activities would be from the same sources.
Bee County has a climate characterized by long, hot summers and cool to warm winters. The moderate temperatures and precipitation result in excellent conditions for developing an ISR mine. The average annual precipitation is about 32 inches with the months from November to March normally the driest and May through October typically having more precipitation due partly to more intense tropical storms. From June through September the normal high temperatures are routinely above 90 degrees Fahrenheit, while the months from December through February are the coolest with average low temperatures below 50 degrees Fahrenheit. Periods of freezing temperatures are generally quite brief and infrequent. Tropical weather from the Gulf of Mexico can occur during the hurricane season and may affect the site area with heavy rain storms. The infrequent freezing weather and abnormally heavy rainfalls are the primary conditions that could cause temporary shutdowns at an operating ISR mine.
The necessary rights for constructing the needed surface processing facilities are in-place on selected lease agreements. Sufficient electric power is believed to be available in the area; however, new lines may be needed to bring additional service to a plant site and well fields. Within a 20-mile radius of the planned Burke Hollow facility there is sufficient population to supply the necessary number of suitable mining personnel.
32
History
The earliest historic uranium exploration at the Burke Hollow Project was the drilling of five exploration holes completed on the Welder lease by Nufuels (Mobil) in 1982. Oxidation/reduction interfaces were intercepted in two of the holes and oxidized tails were logged in three of the holes. In 1993 Total Minerals conducted a short reconnaissance exploration drilling program and completed a total of 12 exploration holes of which 11 intersected anomalous gamma ray log signatures indicative of uranium mineralization. The resulting 12 log files include good quality electric logs, with each log file containing a detailed lithological report based on drill hole cuttings prepared by Total Mineral’s field geologists who were supervising and monitoring the drilling activity contemporaneously.
All of the boreholes were drilled using contracted truck-mounted drilling rigs. The holes were drilled by conventional rotary drilling methods using drilling mud fluids. All uranium exploration at the Burke Hollow Project has been conducted with vertical drill holes. Drill cuttings were typically collected from the drilling fluid returns circulating up the annulus of the borehole. These samples were generally taken at five foot intervals and laid out on the ground in consecutive rows of 20 by the drill crew for review and description by a geologist. Upon completion, the holes were logged for gamma ray, self-potential and resistance by contract logging companies. Century Geophysical was the logging company utilized by both Nufuels and Total Minerals, and Century Geophysical provided primarily digital data. A tool recording down-hole deviation was also utilized for each of the holes drilled.
This description of previous exploration work undertaken at the Burke Hollow Project is based primarily on gamma ray and electric logs along with several small maps and cross-sections constructed by Total Minerals.
The historic data package obtained by us for a portion of the current Burke Hollow Project area provided the above described information. Based on the very limited number of drill holes, no meaningful resource or reserve determination was made by either Nufuels or Total Minerals. The actual drilling and geophysical logging results, however, have been determined to be properly conducted to current industry standards and usable by our exploration staff in their geologic investigation.
The only historic work relating to uranium exploration or mining is the early exploration work done by Nufuels in 1982 and by Total Minerals in 1993 as described above. There has been no known ownership of the Burke Hollow property by a mining company and no prior ownership or changes in ownership for the property are known by our Company or are relevant to the project.
Geological Setting
Regional Geology
The Burke Hollow Project area is situated within the Texas Gulf Coastal Plain physiographic province that is geologically characterized by sedimentary deposits that typically dip and thicken toward the Gulf of Mexico from the northwest source areas. Additionally, the regional dip generally increases with distance in the down dip direction as the overall thickness of sediments increase. The sedimentary units are dominantly continental clastic deposits with some underlying near shore and shallow marine facies. The uranium-bearing units of South Texas are virtually all sands and sandstones in Tertiary formations ranging in age from Eocene (oldest) to Lower Pliocene (youngest). At Burke Hollow, deposits are hosted by the Goliad Formation of Lower Pliocene to Miocene age.
The Project area, located about 18 miles southeast of Beeville, which is the county seat of Bee County, is situated in the major northeast-southwest trending Goliad Formation of fluvial origin. The Geologic Atlas of Texas, Beeville-Bay City Sheet (Texas Bureau of Economic Geology, Revised 1987), indicates that a thin layer of Pleistocene-aged Lissie Formation overlies the Miocene Goliad Formation. The map below shows the surface geology at the Burke Hollow Project.

The Goliad Formation was originally classified as Pliocene in age, but the formation has been reclassified as early Pliocene to middle Miocene after research revealed the presence of indigenous Miocene-aged mega-fossils occurring in upper Goliad sands. The lower Goliad fluvial sands are correlative with down-dip strata containing benthic foraminifera, indicative of a Miocene age (Baskin and Hulbert, 2008, GCAGS Transactions, v. 58, p. 93-101). The Geology of Texas map published by The Bureau of Economic Geology in 1992 classifies the Goliad as Miocene.
Local and Property Geology
The uranium-bearing sands of the Goliad Formation at the project site occur beneath a thin layer of Lissie Formation sand, silt, clay and gravel, which covers most of the project area with a total thickness of approximately 35 feet on the western side to approximately 70 feet thickness on the downdip eastern side of the project. The Goliad Formation underlies the Lissie and is present at depths ranging from 35 feet to approximately 1,050 feet in depth on the eastern side of the property. We have determined that uranium mineralization discovered to date occurs within at least four individual sand units in the Upper Goliad at depths generally ranging from 160 feet to 500 feet, and within two deeper sand units in the Lower Goliad located between 900 feet to 950 feet in depth.
The Goliad sand is one of the principal water-bearing formations in Bee County capable of yielding moderate to large quantities of fresh to slightly saline water in the south half of Bee County, which includes the project area.
The hydrogeological characteristics of the water-bearing Goliad sands at the Burke Hollow Project have not yet been determined, but required hydrogeological tests will determine the hydraulic character of the sands and the confining beds separating the individual sand zones. Information regarding the water-bearing characteristics of the Goliad sands from aquifer tests of Beeville and Refugio City supply wells (O.C. Dale, et al., 1957) reported an average coefficient of permeability of about 100 gallons per day per square foot. This would be the equivalent coefficient of transmissivity of approximately 2,500 gallons per day per foot for a 25-foot thick sand. It is likely that the uranium-bearing mineralized sand zones at the Burke Hollow Project will have similar hydraulic characteristics.
There are at least two northeast-southwest trending faults at the Burke Hollow Project that are likely related to the formation of the uranium mineralization. These faults are shown at a depth of approximately 3,500 feet below ground surface based on petroleum industry maps and extend upward into the Goliad Formation. The northwesterly fault is a typical Gulf Coast normal fault, downthrown toward the coast, while the southeastern fault is an antithetic fault downthrown to the northwest, forming a graben structure. The presence of these faults is likely related to the increased mineralization at the site. The faulting has probably served as a conduit for reducing waters/gases migrating from deeper horizons as well as altering the groundwater flow system in the uranium-bearing sands.

Mineralization
The Burke Hollow Project uranium-bearing units occur as multiple roll-front type deposits in vertically stacked sands and sandstones. Groundwater flowing from northwest to southeast in the Goliad sands likely contained low concentrations of dissolved uranium resulting from oxidizing conditions and the relatively short distance from the recharge area. The geochemical conditions in the sands near the project changed from oxidizing to reducing due to an influx of reductants. Hydrogen sulfide and/or methane dissolved in groundwater are likely sources for creating a reduction-oxidation boundary in the area with consequent precipitation and concentration of uranium mineralization.
Specific identification of the uranium minerals has not yet been determined at the Burke Hollow Project. The very fine uranium minerals found coating quartz grains and within the interstices in most South Texas sand and sandstone roll-front deposits has generally been found to be dominantly uraninite and, to a lesser extent, coffinite. No uraninite has been identified on the Burke Hollow Project and the presence of uraninite on other properties does not mean that such mineralization will be found at the Burke Hollow Project. Detailed petrographic examination of disseminated uranium mineralization within sands/sandstones is generally not suitable for identification of the specific uranium minerals. Laboratory analysis such as x-ray diffraction may be used to identify the minerals, however, the specific mineral species typically found in reduced sands are generally similar in South Texas ISR projects and leaching characteristics are also similar. Based on the experience of the ISR mines throughout South Texas, the use of gamma-ray logging with a calibrated logging probe has become the standard method to determine the thickness and estimated grade of uranium bearing minerals.
At the project site the Goliad Formation is located near the surface underlying the Lissie Formation, and extends to depths exceeding 1,050 feet on the eastern side of the property. Uranium mineralization discovered to date occurs in multiple sand/sandstone units that are all below the saturated zone. These are the Goliad Lower A sand, the Goliad Upper B sand, the Goliad Lower B sand and the Goliad D sand. The sands are fluvial-deltaic in origin, and thicken and thin across the project site. Each zone is hydrologically separated by clay or silty clay beds. The uranium deposits discovered to date range from several feet to over 30 feet in thickness. The C-shaped configuration is typically convex in a down-dip direction with tails trailing on the up-dip side.
Update to July 31, 2021
During Fiscal 2021, a total of 81 exploration holes totaling 38,785 feet were drilled at the Burke Hollow Project to depths ranging from a minimum of 420 feet to a maximum 500 feet, with an average depth of 479 feet. Cumulative to July 31, 2021, a total of 810 exploration holes and 107 monitor wells totaling 423,049 feet have been drilled to depths ranging from a minimum of 150 feet to a maximum of 1,100 feet, with an average depth of 460 feet.
As of July 31, 2021, a total of 30 regional baseline monitor wells have been installed in order to establish baseline water quality in both the Goliad Lower A and Goliad Lower B sands. Additionally, a total of 72 cased monitor wells were installed in the area which will constitute PAA-1 at Burke Hollow. With respect to permitting, a pre-operational groundwater characterization sampling program from the drilling of the regional baseline monitor wells was completed in February 2014. A drainage study of the proposed license boundary was completed in January 2013 and encompasses the first three production areas. Archeology, socioeconomic and ecology studies for the project were all completed by December 2013. Two Class I disposal well applications were submitted and final permits were issued by the TCEQ in July 2015. The final Mine Area Permit was issued by the TCEQ in December 2016 and an Aquifer Exemption was approved by the EPA in March 2017. The final RML was issued by the TCEQ in February 2019.
An earlier Technical Report dated February 27, 2013 for the Burke Hollow Project was prepared in accordance with the provisions of NI 43-101 by Thomas A. Carothers, P.G., a consulting geologist, and filed by us on SEDAR. An updated Technical Report, dated October 6, 2014, was prepared in accordance with the provisions of NI 43-101 by Andrew W. Kurrus III, P. G., with Clyde L. Yancey, P.G., serving as the Qualified Person under NI 43-101.

Goliad Project, Goliad County, Texas
Property Description and Location
The Goliad Project is comprised of seven leases covering 637 acres located in Texas near the northeast end of the extensive South Texas Uranium Trend. The Goliad Project consists of multiple leases that would allow the mining of uranium by ISR methods while utilizing the land surface (with variable conditions), as needed, for mining wells and aboveground facilities for fluid processing and ore capture during the mining and groundwater restoration phases of the Project. The Goliad Project area is about 14 miles north of the town of Goliad and is located on the east side of US route 77A/183, a primary highway that intersects with US 59 in Goliad and IH-10 to the north. The approximate center of the Project area is 28° 52’ 7” N latitude, 97° 20’ 36” W longitude. Site drilling roads are mostly gravel based and allow reasonable weather access for trucks and cars. A location map for the Goliad Project is shown below:
Virtually all mining in Texas is on private lands with leases negotiated with each individual landowner/mineral owner. Moore Energy Corporation (“Moore Energy”) obtained leases for exploration work in the project area in the early 1980s and completed an extensive drilling program resulting in a historic uranium mineral estimate in 1985. We obtained mining leases from individuals and by assignment from a private entity in 2006.
The majority of the Goliad leases have starting dates in 2005 or 2006 with an initial term of five years and a five-year renewal option. The various lease fees and royalty conditions are negotiated with individual lessors and terms may vary from lease to lease. We have amended or renewed all of these leases that had past their five-year renewal periods to extend the time period for an additional 10 years.
No historic uranium mining is known to have occurred on any of the Goliad Project lease properties and only state permitted uranium exploration drilling has taken place. There are believed to be no existing environmental liabilities at the property leases. Prior to any mining activity at the Goliad Project, we are required to obtain an RML, a large area UIC Permit and a PAA Permit for each wellfield developed for mining within the Mine Permit area. In addition, a waste disposal well will, if needed, require a separate UIC Mine permit. These permits will be issued by Texas regulatory agencies. The current drilling and abandonment of uranium exploration holes on any of the leases is permitted by the RCT. Potential future environmental liability as a result of the mining must be addressed by the permit holder jointly with the permit granting agency. Most permits now have bonding requirements for ensuring that the restoration of groundwater, the land surface and any ancillary facility structures or equipment is properly completed.
36
Accessibility, Climate, Local Resources, Infrastructure and Physiography
The Goliad Project area is situated in the interior portion of the Gulf Coastal Plain physiographic province. The area is characterized by rolling topography with parallel to sub-parallel ridges and valleys. There is about 130 feet of relief at the site with ground surface elevations ranging from a low of 150 feet to a high of 280 feet above mean sea level. The leased property for the Goliad Project is used mostly for livestock grazing pasture and woodland. The overall property area is shown as having a Post Oak Woods, Forest and Grassland Mosaic vegetation/cover type.
The site property is accessed from combined route US 77A/183 that trends north-south to the west of the property. Highway FM 1961 intersects with 77A-183 at the crossroad town of Weser. Highway FM 1961 to the east of the intersection trends along the south side of the property. Access from either of these roads into the property is via vehicular traffic on private gravel roads.
The property is in a rural setting at the north end of Goliad County. The nearest population centers are Goliad, 14 miles south, Cuero, 18 miles north, and Victoria, about 30 miles east. While Goliad and Cuero are relatively small towns, they provide basic needs for food and lodging and some supplies. Victoria is a much larger city and provides a well-developed infrastructure that has resulted from being a regional center to support oil and gas exploration and production. The Goliad Project site area generally has very good accessibility for light to heavy equipment. There is an excellent network of county, state and federal highways that serve the region and the moderate topography, with dominantly sandy, well-drained soils, which provide good construction conditions for building gravel site roads necessary for site access.
The climate in Goliad County is mild with hot summers and cool to warm winters. The moderate temperatures and precipitation result in excellent conditions for developing an ISR mine. Periods of freezing temperatures are generally very brief and infrequent. Tropical weather from the Gulf of Mexico can occur during the hurricane season and may affect the site area with heavy rainfall. The periodic freezing weather and abnormally heavy rainfall are the primary conditions that can cause temporary shutdowns. Otherwise there is not a regular non-operating season.
The necessary rights for constructing needed surface processing facilities are in-place on selected lease agreements. Sufficient electric power is believed to be available in the area; however, new lines may be needed to bring additional service to the plant site and wellfields. We believe that within a 30-mile radius of the planned Goliad Project facility there is sufficient population to supply the necessary number of suitable mining personnel.
History
Ownership History of the Property
There has been a long history of oil and gas exploration and production in the area and oil and gas is still a primary part of the economy for the relatively lightly populated county. In the period from October 1979 to June 1980, as a part of a large oil, gas and other minerals lease holding (approximately 55,000 acres), Coastal Uranium utilized the opportunity to drill several widely spaced exploration holes in the region. There were reported to be eight holes drilled at or near the Goliad Project area.
In the early 1980s Moore Energy obtained access to review some of the Coastal Uranium wide-spaced drilling exploration data. The review resulted in Moore Energy obtaining several leases from Coastal Uranium, including several of the current Goliad Project leases. During the period from March 1983 through August 1984, Moore Energy conducted an exploration program in the Goliad Project area. No further drilling was done at the Goliad Project area until we obtained the leases through assignment from a private entity and from individual mineral owners.
37
Exploration and Pre-extraction Work Undertaken
This description of previous exploration and pre-extraction work undertaken at the Goliad Project is based primarily on electric logs and maps produced by Moore Energy during the period 1983 to 1984. Moore Energy completed 479 borings on various leases. Eight widespread exploration borings were completed by Coastal Uranium in 1980. We obtained leases through an assignment from a private entity in 2006 and from individual mineral owners thereafter and began confirmation drilling in May 2006.
In December 2010, the TCEQ approved the mine permit and the production area authorization for PAA-1 and granted the request for the designation of an Aquifer Exemption for us. In December 2011, an RML was issued by the TCEQ. All other state-level permits and authorizations have been received including a Class III Injection Well Permit (Mine Permit), two Class I Injection Well Permits (disposal well permits), a PAA for its first production area, a Permit by Rule (air permit exemption) and an Aquifer Exemption for which we received concurrence from the regional EPA.
A Technical Report, dated March 7, 2008 for the Goliad Project, prepared in accordance with the provisions of NI 43-101, was completed by Thomas A. Carothers, P.G., a consulting geologist, and filed by us on SEDAR.
Geological Setting
Regional Geology
The Goliad Project area is situated in the Texas Gulf Coastal Plain physiographic province that is geologically characterized by sedimentary deposits that typically dip and thicken toward the Gulf of Mexico from the northwest source areas. Additionally, the regional dip generally increases with distance in the down dip direction as the overall thickness of sediments increase. The sedimentary units are dominantly continental clastic deposits with some near shore and shallow marine facies. The uranium-bearing units are virtually all sands and sandstones in Tertiary formations ranging in age from Eocene (oldest) to Upper Miocene (youngest).
Local and Property Geology
The surface of the property is all within the outcrop area of the Goliad Formation (Figure 4-3). The mineralized units are sands and sandstone within the Goliad Formation and are designated by us as the A through D sands from younger (upper) to older (lower), respectively. The sand units are generally fine to medium grained sands with silt and varying amounts of secondary calcite. The sand units vary in color depending upon the degree of oxidation-reduction and could be from light brown-tan to greys. The sand units are generally separated from each other by silty clay or clayey silts that serve as confining units between the sand units.
38
The Goliad Formation at the project site occurs from the surface to a depth of about 500 feet. Depending upon the land surface elevation, groundwater occurs in the sands of the formation below depths of about 30 to 60 feet. The four sand/sandstone zones (A-D) designated as containing uranium mineralization at the site are all considered to be a part of the Gulf Coast Aquifer on a regional basis. At the project area, however, each zone is a hydrogeologic unit with similar but variable characteristics. The A Zone is the uppermost unit and based on resistance logs groundwater in this unit may be unconfined over portions of the site. The three deeper zones are confined units with confining clays and silts above and below the water-bearing unit.
Groundwater from sands of the Goliad Formation is used for water supplies over much of the northern portion of Goliad County. Water quality in the Goliad Formation is variable and wells typically can yield small to moderate amounts of water. Data indicates an approximate average hydraulic conductivity of the water-bearing zones of the Goliad Formation in Goliad County is 100 gallons per day per square foot. Based on this value, a 20-foot sand unit would have an approximate transmissivity of 2,000 gallons per day. With sufficient available drawdown properly completed ISR wells could have average yields in the range of 25 to 50 gallons per minute.
39
The site area structures include two faults that intersect and offset the mineralized units. These faults are normal, with one downthrown toward the coast and one downthrown toward the northwest. The fault throws range from about 40 to 80 feet.
Project Type
The Goliad Project is characteristic of other known Goliad sand/sandstone deposits in South Texas. The mineralization occurs within fluvial sands and silts as roll-front deposits that are typically a “C” or cutoff “C” shape. The roll-fronts are generally associated with an extended oxidation-reduction boundary or front.
The other Goliad projects in the region include the Palangana Mine, the Kingsville Dome mine southeast of Kingsville, the Rosita mine west of Alice, the Mesteña Alta Mesa mine in Brooks County and the former Mt. Lucas mine at Lake Corpus Christi. These mines are all located south of the Goliad Project from about 60 to 160 miles. The average tons and uranium grade information for these mines is not known, but all these ISR projects mining Goliad Formation sand units have been very successful with the following characteristics in common: excellent leaching characteristics rate and favorable hydraulic conductivity of host sands.
At the Goliad Project there are four stacked mineralized sand horizons (A-D) that are separated vertically by zones of finer sand, silt and clay. Deposition and concentration of uranium in the Goliad Formation likely resulted due to a combination of leaching of uranium from volcanic tuff or ash deposits within the Goliad Formation or erosion of uranium-bearing materials from older Oakville deposits. The leaching process occurred near the outcrop area where recharge of oxidizing groundwater increased the solubility of uranium minerals in the interstices and coating sand grains in the sediments. Subsequent downgradient migration of the soluble uranium within the oxygenated groundwater continued until the geochemical conditions became reducing and uranium minerals were deposited in roll-front or tabular bodies due to varying stratigraphic or structural conditions.
There are at least two northeast-southwest trending faults at the Goliad property that are likely related to the formation of the Goliad Project mineralization. The northwesterly fault is a typical Gulf Coast normal fault, downthrown toward the coast, while the southeastern fault is downthrown to the northwest, forming a graben structure. Both faults are normal faults. Throw on the northwest fault is about 75 feet and the southeast fault has about 50 feet of throw. The presence of these faults is likely related to the increased mineralization at the site. The faulting has probably served as a conduit for reducing waters/gases to migrate from deeper horizons as well as altering the groundwater flow system in the uranium-bearing sands.
Mineralization
The Goliad Project uranium-bearing units occur as multiple roll-front type structures in vertically stacked sands and sandstones. Groundwater flowing from northwest to southeast in the Goliad sands likely contained low concentrations of dissolved uranium resulting from oxidizing conditions and the relatively short distance from the recharge area. The geochemical conditions in the sands near our property changed from oxidizing to reducing due to an influx of reductants. Hydrogen sulfide and/or methane dissolved in groundwater are likely sources of creating a reduction-oxidation boundary in the area with consequent precipitation and concentration of uranium mineralization.
Specific identification of the uranium minerals has not been determined at the Goliad Project. The very fine uranium minerals found coating quartz grains and within the interstices in most South Texas sand and sandstone roll-front deposits has generally been found to be dominantly uraninite. No uraninite has been identified on the Goliad Project and the presence of uraninite on other properties does not mean that such mineralization will be found on the Goliad Project. Detailed petrographic examination of disseminated uranium mineralization within sands/sandstones is generally not suitable for identification of the specific uranium minerals. Laboratory equipment such as x-ray diffraction units may be used to identify the minerals, however, the specific mineral species typically found in reduced sands are generally similar in South Texas ISR projects and leaching characteristics are also similar. Based on the experience of the ISR mines throughout south Texas, the use of gamma-ray logging with a calibrated logging probe has become the standard method to determine the thickness and estimated grade of uranium bearing minerals.
40
At the Goliad Project site the Goliad Formation is exposed at the surface and extends to depths exceeding 500 feet. Uranium mineralization occurs in four sand/sandstone units that are all below the saturated zone. The zones are designated A to D from the top to the bottom of the sequence. The sands are fluvial-deltaic in origin, and thicken and thin across the Project site. Each zone is hydrologically separated by 10 to 50 feet or more of clay or silty clay. The uranium deposits are tabular in nature and can range from about one foot to over 45 feet in thickness. The “C” shaped configuration is typically convex in a downdip direction with leading edge tails on the upper end. Most of the exploration and delineation holes with elevated gamma ray log anomalies are situated within a southwest-northeast trending graben and most of the gamma ray anomaly holes are situated along the northernmost of the two faults comprising the graben. This northernmost fault is downthrown to the southeast, which is typical for the majority of faults along the Texas coastal area.
Leach Amenability
Mineral processing or metallurgical testing was not reported as being conducted on any of the samples drilled or recovered during the Moore Energy exploration in the mid-1980s. We submitted selected core samples from our core hole # 30892-111C to Energy Laboratories, Inc. in Casper, Wyoming, in January 2007. These samples from the Goliad Project were sent to the laboratory for leach amenability studies intended to demonstrate that uranium mineralization at the property was capable of being leached using conventional in situ leach chemistry. The tests do not approximate other in-situ variables (permeability, porosity and pressure) but provide an indication of a sample’s reaction rate and the potential chemical recovery.
Split sections of core were placed in laboratory containers and a lixiviate solution with 2.0 grams per liter HCO 3 (NaHCO 3 ) and either 0.50 or 0.25 g/L of H 2 O 2 (hydrogen peroxide) was added to each test container. The containers were then rotated at 30 rpm for 16 hours. The lixiviate was then extracted from each test container and analyzed for uranium, molybdenum, sodium, sulfate, alkalinity (bicarbonate, carbonate), pH and conductance. A clean charge of lixiviate was added and the container rotated another 16 hours. Each sample rotation and lixiviate charge cycle was representative of five pore volumes with chemical analyses after each cycle. The cycle was repeated for a total of six cycles or the equivalent of 30 pore volumes.
The four core samples subjected to the leach amenability tests were determined to contain from 0.04% to 0.08% cU 3 O 8 before testing . Leach tests conducted on the core samples from the A-Zone indicate leach efficiencies of 60% to 80% U 3 O 8 extraction while the tails analyses indicate efficiencies of 87% to 89%. The differences between the two calculations involve the loss of solid clay-based materials during multiple filtrations. Based on post leach solids analysis, the core intervals were leachable to a very favorable 86% to 89%. After tests the tails were reanalyzed for uranium concentration to determine the recovery, which ranged on the four samples using two methods from 60% to 89%.
Laboratory amenability testing of the cores samples indicated that the uranium (dissolved elemental U) recoveries ranged from 86.4% to 88.9% in the four tests. These results show that the mineralized intervals at the Goliad Project are very amenable to ISR mining even when exposed to only one-half of the oxidant concentration normally used in the leach amenability test. Based on the ISR mining of the Catahoula and Oakville uranium deposits, as well as discussions with other Goliad deposit mining personnel, the geologically younger deposits in Texas (Goliad formation) have typically been the most amenable to in-situ leaching. The uranium recovery is generally more complete (% recovery) and occurs in a shorter time period. Both of these factors are important for ISR pre-extraction economics.
Based on the amenability test results, the size of the mineralization at the Goliad Project, the geologic setting and the current and projected future demand and price of uranium, the most feasible and cost effective mining method for the Goliad property uranium is by ISR. This method is most suitable for the size and grade of the deposits in sands that are below the water table and situated at depths that would be prohibitive for open pit or underground mining.
The amenability testing described above was conducted on core recovered from four depth intervals from one boring. While this was a limited sampling for this property, the samples are believed to be generally representative of the characteristics of the mineralized intervals and the determined recovery ranges for these intervals is considered to be reliable. Two of the four samples tested contained approximately 0.08% cU 3 O 8 and two contained lower grades of uranium (~0.04% cU 3 O 8 ). Energy Laboratories, Inc. in Casper, Wyoming, conducted the laboratory testing for this project. The laboratory has been in business since 1952, is fully certified, but not ISO certified. Certifications include the EPA, the NRC and the following U.S. states: Arizona, California, Colorado, Florida, Indiana, Nevada, Oregon, South Dakota, Texas, Utah and Washington.

in June 2014, the EPA reaffirmed its earlier decision to uphold the granting of our existing AE, with the exception of a northwestern portion containing less than 10% of the uranium resource which was withdrawn, but not denied, from the AE area until additional information is provided in the normal course of mine development;
●
during Fiscal 2014, 34 delineation holes totaling 9,819 feet were drilled at the Goliad Project to depths ranging from a minimum of 160 feet to a maximum of 480 feet, with an average depth of 289 feet. During Fiscal 2015, no further drilling activities were conducted. At July 31, 2015, approximately 992 confirmation-delineation holes totaling 348,434 feet have been drilled by us to confirm and expand the mineralization base at the Goliad Project;
●
construction of a three-phase electrical power system for the entire project and a large caliche site pad for the main plant complex and disposal well have been completed; and
●
processing equipment for the construction of the satellite facility and wellfield, including long-lead items such as ion exchange vessels, have been received.
On or about March 9, 2011, the TCEQ granted our Company’s applications for a Class III Injection Well Permit, PAA and AE for the Goliad Project. On or about December 4, 2012, the EPA concurred with the TCEQ issuance of the AE permit. With the receipt of this concurrence, the final authorization required for uranium extraction, the Goliad Project achieved fully-permitted status. On or about May 24, 2011, a group of petitioners, inclusive of Goliad County, appealed the TCEQ action to the 250 th District Court in Travis County, Texas. A motion filed by us to intervene in this matter was granted. The petitioners’ appeal lay dormant until on or about June 14, 2013, when the petitioners filed their initial brief in support of their position. On or about January 18, 2013, a different group of petitioners, exclusive of Goliad County, filed a petition for review with the Court of Appeals for the Fifth Circuit in the United States (the “Fifth Circuit”) to appeal the EPA’s decision. On or about March 5, 2013, a motion filed by us to intervene in this matter was granted. The parties attempted to resolve both appeals and, to facilitate discussions and to avoid further legal costs, the parties jointly agreed, through mediation which was initially conducted through the Fifth Circuit on or about August 8, 2013, to abate the proceedings in the State District Court. On or about August 21, 2013, the State District Court agreed to abate the proceedings. The EPA subsequently filed a motion to remand without vacatur with the Fifth Circuit wherein the EPA’s stated purpose was to elicit additional public input and further explain its rationale for the approval. In requesting the remand without vacatur, which would allow the AE to remain in place during the review period, the EPA denied the existence of legal error and stated that it was unaware of any additional information that would merit reversal of the AE. We and the TCEQ filed a request to the Fifth Circuit for the motion to remand without vacatur, if granted, to be limited to a 60-day review period. On December 9, 2013, by way of a procedural order from a three-judge panel of the Fifth Circuit, the Court granted the remand without vacatur and initially limited the review period to 60 days. In March of 2014, at the EPA’s request, the Fifth Circuit extended the EPA’s time period for review and additionally, during that same period, we conducted a joint groundwater survey of the site, the result of which reaffirmed our previously filed groundwater direction studies. On or about June 17, 2014, the EPA reaffirmed its earlier decision to uphold the granting of our existing AE, with the exception of a northwestern portion containing less than 10% of the uranium resource which was withdrawn, but not denied, from the AE area until additional information is provided in the normal course of mine development. On or about September 9, 2014, the petitioners filed a status report with the State District Court which included a request to remove the stay agreed to in August 2013 and to set a briefing schedule (the “Status Report”). In that Status Report, the petitioners also stated that they had decided not to pursue their appeal at the Fifth Circuit. We continue to believe that the pending appeal is without merit and we are continuing forward as planned towards uranium extraction at its fully-permitted Goliad Project.

Mineral Exploration Projects
We hold mineral rights in the U.S. States of Arizona, Colorado, New Mexico, Texas and Wyoming, in Canada and in the Republic of Paraguay by way of federal, state and provincial mining claims and private mineral leases and mineral concessions.
We plan to conduct exploration programs on these mineral exploration properties with the objective of determining the existence of economic concentrations of uranium. We have not established proven or probable reserves, as defined by the SEC under Industry Guide 7, through the completion of a “final” or “bankable” feasibility study for any of the uranium projects discussed below. Furthermore, we have no plans to establish proven or probable reserves for any of our uranium projects for which we plan on utilizing ISR mining.
Arizona
All of our Arizona claims and state leases were previously the subject of exploration drilling for the search of uranium by companies such as Union 76 Oil, Urangesellschaft, Wyoming Minerals, Noranda, Inc., Uranerz Energy Corp. (“Uranerz”), Homestake Mining Co., Occidental Minerals and Oklahoma Public Services. Claims staked directly by us have been in areas known for uranium occurrences as shown in the Arizona State publication “Occurrences of Uranium in Miscellaneous Sedimentary Formations, Diatremes and Pipes and Veins”.

The Anderson Project is an 8,268-acre property located in Yavapai County, west-central Arizona, approximately 75 miles northwest of Phoenix and 43 miles northwest of Wickenburg (latitude 34°18’29” N and longitude 113°16’32” W, datum WGS84). The general area is situated along the northeast margin of the Date Creek Basin. The Anderson Project is located on the south side of the Santa Maria River approximately 13 miles west of State Highway 93. The Anderson Project occupies part or all of Sections 1 and 3, 9 through 16, 21 through 27, and 34 through 36 of Township 11 North, Range 10 West and portions of Sections 18, 19, and 30 of Township 11 North Range 9 West of the Gila and Salt River Base Meridian.

Accessibility, Climate, Local Resources, Infrastructure and Physiography
The Anderson Project is accessed by paved, all-weather gravel and dirt roads. The property is accessed via the Alamo Lake turnoff, located approximately 21 miles northwest of Wickenburg on Arizona State Highway 93 (Joshua Tree Parkway), then driving 0.25 miles north of mile marker 179, and then following the Alamo Road for 5.8 miles to the Pipeline Ranch Road turnoff. The road passes through the Pipeline Ranch, located in the bottom of Date Creek Wash and continues for approximately 6.3 miles to FR 7581. The property boundary is located 1.4 miles north on FR 7581. There are alternate dirt roads, including a 15-mile primitive road from Highway 93 over Aso Pass (2,900-foot elevation).
The Anderson Project is located in the northeast portion of the Date Creek Basin. The basin consists of low undulating terrain centrally dissected by Date Creek Wash. The site lies along the south bank of the Santa Maria River which runs along the northern edge of the basin. Elevations above sea level are between 1,700 feet and 2,400 feet. Maximum local topographic relief at the site is approximately 700 feet.
Vegetation on the property is typical of the Sonoran Desert of central Arizona and consists predominantly of Joshua trees, palo verde bushes, saguaro, cholla, ocotillo, creosote bushes and desert grasses. Fauna includes jackrabbits, rattlesnakes, roadrunners, desert tortoise, various lizards and less common mule deer, wild burros and mules.
The alluvial valley of the Santa Maria River varies substantially in width and depth to bedrock. The volume of alluvium, and particularly the depth of the material, influences the proportion of surface flow to underflow in the river valley. The groundwater in the alluvium consists of underflow that is forced toward the surface as the depth of the alluvium decreases.
44
The climate is arid, with hot summers and mild winters. Annual rainfall averages 10 to 12 inches with rain showers from January through March and during summer thunderstorms. Snowfall is rare. On average temperatures range between a low of 31°F during winter months and a high of 104°F during summer months. Temperature extremes of 10°F in winter and 120°F in summer have been recorded. The climate is favorable for year-round mining operations and requires no special operational or infrastructure provisions that relate to weather.
Various water wells exist on and near the Anderson Project that can support large-scale mining operations. There is plenty of usable land space to locate processing plants, heap leach pads, tailings storage areas, waste disposal areas and other infrastructure development associated with large-scale mining. The Anderson Project includes most of a 195-acre area designated by the BLM as “disturbed” resulting from surface mining in the 1950s. It may be possible to expedite the permitting process for future metallurgical exploration and mining activities, including waste disposal within the disturbed area.
The Anderson Project area is undeveloped with the exception of various access and drill roads and various water wells previously constructed. No utilities exist on or adjacent to the area. A transmission power line runs northwest-southeast along Highway 93, approximately eight miles to the east, however, direct access to the power line may be obstructed by the Arrastra Mountain Wilderness and Tres Alamos Wilderness located between the power line and the Anderson Project. The construction of a power line would require routing along one of the existing road corridors, a distance of 16.2 miles to the project boundary.
The nearest town is Congress (population 1,700) located 32 road miles to the east. The nearest major housing, supply center and rail terminal is in Wickenburg (population 6,363) located approximately 43 miles from the Anderson Project by road. Phoenix (population 1.45 million) is approximately 100 miles to the southeast by road and is the nearest major industrial and commercial airline terminal. Kingman (population 24,000) is located approximately 110 miles to the northwest by road. Our surface rights encompass 15.4 square miles which is sufficient for the surface structures associated with any proposed mining operation.
History
In January 1955, T.R. Anderson of Sacramento, California, detected anomalous radioactivity in the vicinity of the Anderson Project using an airborne scintillometer. After a ground check revealed uranium oxide in outcrop, numerous claims were staked. The “Anderson Mine”, as the operation was known at the time, was drilled and mined by Mr. Anderson. Work between 1955 and 1959 resulted in 10,758 tons that averaged 0.15% U 3 O 8 and 33,230 pounds U 3 O 8 were shipped to Tuba City, Arizona, for custom milling. In 1959, production stopped when the Atomic Energy Commission ended the purchasing program.
45
During 1967 and 1968, Getty Oil Company (“Getty”) secured an option on claims in the northern portion of the Anderson Project. Some drilling and downhole gamma logging was conducted during the option period, but this failed to locate a sizeable uranium deposit. In 1968, Getty dropped their option.
In 1974 the increasing price of uranium created a renewed interest in the vicinity of the Anderson Project. Following a field check and an evaluation of the 1968 Getty drill data, MinEx optioned the northern portion of the current Anderson Project.
In 1975 MinEx purchased the northern portion of the current Anderson Project after a 53-hole, 5,800 m (19,000 feet) drilling program on 250 m centers confirmed a much greater uranium resource potential than had been interpreted from the 1968 Getty gamma log data. Further exploration work, consisting of a 180-hole, 22,555 m (74,000 feet) drill and core program on 120 m centers was conducted from November 1975 through February 1976 to further delineate the uranium resources. By 1980 MinEx had completed a total of 1,054 holes by rotary and core drilling.
In 1977 the Palmerita Ranch, located 11 km west of the deposit along the Santa Maria River, was acquired by MinEx to provide a water source for the operations in the event that closer sources proved inadequate. Based on favorable economics, indicated in a preliminary feasibility study completed by Morrison-Knudsen Company, Inc. in December 1977, a detailed final feasibility study was undertaken early in 1978 to evaluate the MinEx holdings on the northern portion of the current Anderson Project.
In 1973 Urangesellschaft expressed an interest in the former Anderson property. Urangesellschaft located a claim block, the “Date Creek Project”, on the down-dip extension of the mineralization immediately to the south of MinEx’s claims. In 1973 to 1982 subsequent drilling programs delineated mineralization from a total of 352 drill holes with 122,744 m (402,773 feet) of rotary and core drilling. The following table summarizes the phases of the historical exploration.

Geologic Setting
Regional Geology
The Anderson Project is located along the northeast margin of the Date Creek Basin of the Basin and Range Province of the western United States. The Date Creek Basin is one of hundreds of Paleogene basins throughout western Arizona, southeastern California, Nevada and western Utah. Paleogene lacustrine and fluvial sediments and Quaternary gravels have filled these basins to depths of several thousand meters. The approximate location of the Basin boundaries is shown in the figure below.
46
The Basin is surrounded by dissected mountain ranges containing Precambrian metamorphic rocks and granites. Surrounding mountain ranges include the Black Mountains to the north and northeast and the Rawhide, Buckskin and McCracken Mountains to the west. To the south and southeast the Basin is bordered by a low drainage divide imposed by the Harcuvar and the Black Mountains. Margins of the Basin are filled with early Paleogene volcanic flows and volcaniclastic sediments. The Basin itself is filled with Oligocene to Miocene lacustrine and deltaic sediments covered by a thick mantle of Quaternary valley fill.
Local and Property Geology
Three major faults cross the Anderson Project: the East Boundary Fault System; Fault 1878; and the West Boundary Fault System. Faults trend predominantly N30ºW to N55ºW and dip steeply (approximately 80º) to the southwest. Another set of faults trending more westerly (N65ºW) are present in the south-central portion of the Anderson Project. A fault set trending northeast-southwest has been speculated by Urangesellschaft and others, but has not been observed in the field. Many of the northwesterly surface water drainage tributaries are developed partially along fault traces.
Minor faults and shear zones occur throughout the Anderson Project. These probably represent fractures with slight offset of strata during differential compaction of the underlying sediments or local adjustment to major faulting.
The largest fold in the area is a broad, gentle, northwest-trending syncline in the southeastern quarter of Section 9, T11N, R10W. Dips reach a maximum of 13º except where modified by shearing. Many smaller folds with amplitudes of several feet are present in the lacustrine strata.
Fault displacements range from a few centimetres to more than 100 m. Fault movement is generally of normal displacement resulting in stair-stepped fault blocks. Local faults also have a tendency to hinge. Minor faulting across the mineralized area is often difficult to discern from variations in sedimentary dips. The lacustrine sediments dip south to southwesterly from 2º to 5º, to a maximum of 15º. Much of this dip is attributed to recurrent faulting during deposition.
47
Nine stratigraphic units were identified on the Anderson Project, listed from oldest to youngest, as follows:
●
Crystalline Intrusive Rocks: coarse-grained to pegmatitic Precambrian granite;
●
Felsic to Intermediate Volcanic: flows, breccias, tuffs and minor intrusive;
●
Felsic to Intermediate Volcaniclastic: ash flows, tuffaceous beds and arkosic sandstone;
●
Andesitic Volcanic: porphyritic andesitic flows with a paleosurface and locally reddish-brown paleosols;
●
Lacustrine Sedimentary rocks: micaceous siltstones and mudstone, calcareous siltstones and silty limestone, thin beds of carbonaceous siltstone and lignitic material and host of uranium mineralization, averaging about 60 m to 100 m thick;
●
Lower Sandstone Conglomerate: arkosic sandstones and conglomerate, averaging about 60 m to 100 m thick;
●
Basaltic Flows and Dikes: amygdular basalt, averaging about 20 m thick;
●
Upper Conglomerate: cobble and boulder conglomerate, partly indurate and locally calcite cemented, averaging about 0 m to 60 m thick; and
●
Quaternary Alluvium: unconsolidated sand and gravel, caliche formed where calcite-cemented.
Uranium mineralization at the Anderson Project occurs exclusively in the sequence of Miocene-age lacustrine lakebed sediments. The lacustrine sediments unconformably overlie the andesitic volcanic unit over most of the Anderson Project. However, to the east of the Anderson Project they overlie the felsic to intermediate volcanic unit.
Evidence suggests that deposition of the lacustrine sediments occurred in a restricted basin less than five km wide by 10 km to 12 km long on the northern edge of an old Paleogene lake. Moving southward, these sediments inter-tongue with siltstones and sandstones. The lakebed sediments represent time-transgressive facies deposited within a narrow, probably shallow, basinal feature. This type of depositional environment exhibits complex relationships between individual facies, lensing out, vertical and horizontal gradation, and interfingering.
The lake sediments include green siltstones and mudstones, white calcareous siltstones, and silty limestone or calcareous tuffaceous material. Much of this material is silicified to varying extents and was derived in part from volcanic ashes and tuffs common throughout the lakebeds. Also present in the lacustrine sequence are zones of carbonaceous siltstone and lignitic material. Along the boundary between the former MinEx and Urangesellschaft properties, drill holes encounter the basal arkosic sandstone. To the south and southwest, lakebeds interfinger with and eventually are replaced by a thick, medium to coarse-grained, arkosic sandstone unit.
Mineralization
Uranium mineralization in outcrops and the pit floor at the old Anderson mine was reported by the U.S. Bureau of Mines in Salt Lake City as tyuyamunite (Ca(UO 2 ) 2 (VO 4 ) 2 ·5-8H 2 O). Carnotite (K(UO 2 ) 2 (VO 4 ) 2 ·3H 2 O), and a rarer silicate mineral, weeksite (K 2 (UO 2 ) 2 (Si 2 O 5 ) 3 ·4H 2 O), were also reported in outcrop samples. Carnotite mineralization occurs as fine coatings and coarse fibrous fillings along fractures and bedding planes and has been noted in shallow drill holes and surface exposures.
The uranium mineralization found at depth on the former Urangesellschaft property was reported by Hazen Research, Inc. (“Hazen Research”) to be poorly crystallized, very fine-grained, amorphous uranium with silica. This could be in the form of either coffinite (U(SiO 4 ) 1-x (OH) 4x ) or uraninite (UO 2 ) in a primary or unoxidized state (Hertzke, 1997). Mineralogical studies performed by Hazen Research (1978a, 1978b, 1978c and 1979) on Urangesellschaft core found that mineralization was associated, for the most part, with organic-rich fractions of the samples. Specifically, the uraniferous material occurs as stringers, irregular masses and disseminations in carbonaceous veinlets with uranium up to 54% as measured by microprobe analysis. X-ray diffraction identified the mineral as coffinite. It is possible that an amorphous, ill-defined uranium silicate with a variable U:Si ratio is precipitated and, under favorable conditions, develops into an identifiable crystalline form (coffinite).
Of special note is the detection of high-grade, low-reflecting uraniferous material occurring with carbonaceous material in the siltstone. Similar assemblages in unoxidized mineralization have also been reported for the former MinEx property.
Urangesellschaft distinguished seven mineralized zones, identified as Horizons A, B, C, D, E, F and G, with the youngest (uppermost) being Horizon A and the oldest (deepest) being Horizon G. The majority of uranium occurs in Horizons A, B and C within the property. A conglomeratic sandstone unit interbeds with these units, but does not contain uranium mineralization; it is referred to as the Barren Sandstone Unit and it lies between Horizon C and Horizon D. Consequently, Horizons A through C have been called the Upper Lakebed Sequence and Horizons D through G have been called the Lower Lakebed Sequence.
48
Grades of mineralization range from 0.025% U 3 O 8 to normal highs of 0.3% to 0.5% U 3 O 8 with intercepts on occasion of 1.0% to 2.0% U 3 O 8 . Secondary enrichment of the syngenetic mineralization is observed along faults and at outcrops.
Exploration
A Light Detection and Ranging (“LiDAR”) survey was performed over the entire project area by Cooper Aerial Surveys Co. (“Cooper Aerial”) on July 9, 2011, between 13:07 UTC and 15:14 UTC (6:07 A.M. and 8:14 A.M., MST). Aerial imagery was collected at the same time. Data was processed using one of two base stations to obtain positional accuracies of between three cm and 10 cm. 24 ground control points showed a root mean square error of 6.7 cm between predicted and measured elevations. Cooper Aerial provided us with a one-meter pixel digital elevation model (DEM) and a 0.61 m contour shape-file derived from the LiDAR data. Cooper Aerial also corrected the ortho imagery with a 0.15 m pixel size. Coordinates were converted from WGS84 to NAD 1983 UTM Zone 12N in meters, and elevation was reported in NAVD 1988 international feet. The conversion caused no distortion in elevations used in the resource model.
We have not performed any drilling to date on the Anderson Project.
A Technical Report, dated June 19, 2012, for the Anderson Project, prepared in accordance with NI 43-101, was completed by Bruce Davis and Robert Simm, consulting geologists, and filed by us on SEDAR.
A PEA, dated July 6, 2014 for the Anderson Project, prepared in accordance with NI 43-101, was completed by Douglas Beahm, PE, PG, and Terence McNulty, PE, and filed by us on SEDAR.
Workman Creek Project
The Workman Creek Project is a 4,036-acre property located in Gila County, Arizona.
The Workman Creek Project consists of seven claim blocks, totaling 198 unpatented mining claims located within Gila County, in the central portion of the State of Arizona. We entered into a property acquisition agreement with Cooper Minerals Inc. on November 7, 2011 for the mineral claims which constitute the Workman Creek Project.
The Workman Creek Project is located in the Sierra Ancha region, approximately 50 kilometres north of Globe, within Gila County, Arizona. Some of the claim blocks can be accessed easily via highway 288, while other claim blocks are only accessible with the use of all-terrain-vehicles. The Sierra Ancha region is host to 18 historic uranium mines which were in operation between 1953 and 1960. During that period, over 122,000 pounds of U 3 O 8 concentrate was produced with an average grade of 0.20% U 3 O 8 .
The Workman Creek Project and surrounding area of the Sierra Ancha region are underlain by igneous and sedimentary rocks of Precambrian age. The sedimentary rocks are nearly flat-lying except for minor undulations near regional-scale monoclines. The Dripping Spring Quartzite is the host rock for uranium mineralization throughout the Sierra Ancha region. Uranium mineralization in the Dripping Spring Quartzite consists of low-grade disseminations and concentrations in fine-grained strata and along bedding planes, and higher-grade layers and veinlets.
Wyoming Minerals Corporation developed the most prominent pre-1960 uranium mines into what they referred to as the “Dripping Springs Project”. In 1980, Wyoming Minerals Corporation contracted Dravo Engineers and Constructors to conduct a feasibility study of the Workman Creek deposits. This study of the “Dripping Springs Project” is within the Workman Creek Project. Shortly after the feasibility study was finished, the uranium market saw a prolonged depression.
A Technical Report, dated July 7, 2012, for the Workman Creek Project, prepared in accordance with NI 43-101, was completed by Neil G. McCallum, P.G., and Gary H. Giroux, P.E., a consulting geologist and engineer, respectively, and filed by us on SEDAR.

Slick Rock Project
Pursuant to a Uranium Mining Lease dated May 23, 2012, we acquired from UR-Energy LLC a mining lease for uranium on our Slick Rock Project located in San Miguel and Montrose Counties, Colorado.
Since January 2011 we have staked a total of 129 claims in the Slick Rock district of the Uravan Mineral Belt. In June 2011 we acquired 103 claims from Spider Rock Mining also in the Slick Rock District for a one-time payment of $500,000. As a result, we now hold a total of 315 contiguous claims in the Slick Rock District. Certain claims of the Slick Rock Project are subject to a 1.0% or 3.0% net smelter royalty, the latter requiring an annual advance royalty payment of $30,000 which began in November 2017.
The Slick Rock Project is located in San Miguel County, Colorado, approximately 24 miles north of the town of Dove Creek. The Slick Rock Project occupies all or parts of sections 15, 16, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 32, 33 and 34 in T44N R18W, NM Principal Meridian, and parts of sections 3, 4 and 5 of T43N R18W, NM Principal Meridian. The Slick Rock Project consists of 315 contiguous mineral lode claims and covers approximately 5,230 acres (8.2 square miles). The Slick Rock Project is bordered to the west by the Department of Energy's (“DOE”) Uranium lease tracts C-SR-13 and C-SR-13A, to the southwest by DOE Uranium lease tract C-SR-14(1) and to the north and northeast by the Sunday / Carnation / Topaz / Saint Jude mine complex, formerly owned by Energy Fuels.
The Slick Rock Project produced uranium and vanadium from 1957 to 1983 via the Burro Mines. The historic production totals of the Burro Mine are as follows:
Production Years
U 3 O 8 Produced (in Pounds)
V 2 O 5 Produced (in Pounds)
1957 to 1971
1,992,898

1971 to 1983
243,825
1,791,798
Total
2,236,723
13,941,457
All uranium/vanadium production came from the Upper Rim Sand of the Salt Wash Member of the Jurassic Morrison Formation.
Within the Slick Rock Project area, the Salt Wash Member is approximately 275 to 400 feet thick. The Fluvial sediments of the Salt Wash were deposited by north to northeast flowing paleostreams. In the project area, these streams were deflected eastward by the paleotopographic high caused by the northwest/southeast trending Gypsum Valley anticline. This allowed for thick accumulations of Salt Wash sediments along the southwestern flank of the anticline and across the project area. The Salt Wash is composed of white to grey, light-buff and rusty-red, fine to medium-grained, cross-bedded, lenticular sandstone interbedded with red, green, or light-gray shale and mudstone. The Salt Wash contains three major sandstone ledges, ranging from 20 to 150 feet in thickness and separated by clay and shale layers. The uppermost thick, continuous sandstone lens is commonly the most highly mineralized of the sequence. The largest Salt Wash uranium deposits are near the edges of thick sandstone where a transition to sandy mudstone takes place, and in the scours or on the flanks of paleostream channels. Mineralized pods average in the range of 3000 tons to as much as 100,000 tons taken from a single cluster of deposits. Locally, deposits attain a thickness of 30 feet, but two to nine foot thicknesses are most common. Minerals are carnotite, tyuamunite and brightly colored vanadates, vanadium hydromica or clay. Unoxidized mineralization is commonly black, consisting or uraninite, coffinite, montroseite and vanadium hydromica or clay.

As at July 31, 2021, we currently own various exploration projects located in the South Texas Uranium Belt. The location and acquisition of these leases are based on historical information contained within our extensive database, as well as current, ongoing geologic analyses by our exploration staff.
Salvo Project
Our Salvo Project is a 1,340-acre property located in Bee County, Texas.
A Phase I exploration drill program was completed in April 2011 with a total of 105 holes drilled. Phase II drilling began at the Salvo Project in October 2011 with two drilling rigs targeting Lower Goliad P and Q sand objectives. A total of 122 exploration and delineation holes for a total of 70,760 feet were drilled during Phase II which was concluded in May 2012. 29 holes (23%) met or exceeded a grade-thickness (“GT”) cutoff of 0.3 GT.
Interpretation of our exploration and delineation drilling, along with historic data from 1982 to 1984 exploration drilling by Mobil and URI, revealed the existence of two ore-bearing redox boundaries within the area, which has the potential to become PAA-1. A significant under-explored extension to this area which exhibits strong mineralization remains open-ended. Future plans would include further exploration/delineation drilling in this area in order to fully identify the extent of the mineralized zones in proposed PAA-1. Historic and recent Company drilling results are being reviewed for future exploration/delineation activities in the Salvo Project in order to fully identify the extent of the mineralized zones.
51
A Technical Report, dated July 16, 2010, for the Salvo Project, prepared in accordance with NI 43-101, was completed by Thomas A. Carothers, P.G., a consulting geologist, and filed by us on SEDAR. A further Technical Report, dated March 31, 2011, for the Salvo Project, prepared in accordance with NI 43-101, was completed by Thomas A. Carothers, P.G., a consulting geologist, and also filed by us on SEDAR.
Longhorn Project
Our Longhorn Project is located in Live Oak County, Texas, which historically has produced uranium by both open pit and ISR methods. The property lies within the historic US Steel Clay West production area where uranium was previously mined utilizing ISR methods along the historic George West district trend. We have an extensive database of information regarding the area including drill maps and over 500 gamma logs. The project lies on trend between two former U.S. Steel production areas, the Boots/Brown and the Pawlik. At least five separate roll-fronts are believed to exist across the project area. Uranium grades within these Oakville deposits ranged from 0.10% to in excess of 0.20% U 3 O 8 according to U.S. Steel reports and historic well logs obtained by us. Well-developed Oakville sands in this area exhibit higher than average uranium grades for South Texas, as shown on many historic gamma ray logs, of which we have at least 500+ pertaining to the project from various databases. These higher than average reported uranium grades were later proven by excellent recoveries in the U.S. Steel ISR production areas.
The property is located approximately 65 miles northwest of Corpus Christi and 55 miles southwest of Hobson. It is comprised of 39 lease agreements covering 651 acres, granting us the exclusive right to explore, develop and mine for uranium. We anticipate that any uranium identified at the Longhorn Project will be extracted using ISR mining and processed at Hobson.

We acquired the Reno Creek Project on August 9, 2017 and the North Reno Creek Project on May 1, 2018.
Reno Creek Project
Our Reno Creek project is located in the Powder River Basin of northeast Wyoming, one of the most prolific uranium producing regions in the U.S. and the home of five producing ISR operations: Cameco’s Smith Ranch/Highland; Cameco’s North Butte satellite; Uranium One’s Willow Creek; Energy Fuels, Inc.’s (“EFR”) Nichols Ranch; and Strata’s Lance project. The planned central processing plant (“CPP”) for the Reno Creek Project is located approximately 12 miles from the nearest town, Wright, Wyoming, with a population of 1,266 in 2019.
The project consists of 18,763 gross acres of properties including a 40-acre CPP site and five major resource units, all within ten miles of the proposed CPP.
Uranium was originally discovered within the project area by several 1960s/1970s mining companies, including Rocky Mountain Energy, Cleveland Cliffs, American Nuclear and TVA, Pathfinder Mines and others. Most of the leases and claims that held the resources were dropped in the late 1990s and early 2000s. In the mid-2000s Strathmore re-staked mining claims and took leases on most of the current project. Strathmore in 2010 sold them to AUC LLC (“AUC”), which was acquired by us in 2017 and is our wholly-owned subsidiary and the operator of the project.
Uranium deposits at the Reno Creek Project lie within a geologically favorable fairway characterized by porous and permeable fluvial sandstones of the Eocene Wasatch Formation. The sandstone aquifers are overlain and underlain by barren sequences of shales and occasional thin coals. A complex series of stacked roll-fronts occur along oxidation/reduction boundaries forming prospective trends that extend for over 40 miles through the greater project area. The deposits occur at shallow depths between 200 to 400 feet in a sparsely populated area with gentle terrain, providing excellent logistics and access.
While much of the trend has been very well explored by AUC and past operators, we believe that excellent upside for further discoveries exists. Company databases include more than 10,000 uranium drill holes and over a 1,000 Coal Bed Methane logs to guide future exploration.
52
Geologists have mapped 10 to 20 miles of roll-fronts on the holdings that are undrilled or under-drilled, providing numerous high-quality exploration targets to expand current resources. During 2012 and 2013, AUC drilled 800 holes along one such trend, adding approximately two million pounds to the resource base.
AUC conducted permitting and licensing activities and received final permits from the Wyoming Department of Environmental Quality (“WDEQ”) and the EPA in 2015 and from the NRC in 2017. The WDEQ issued its Permit to Mine in July 2015, and also referred its recommended approval of the AE to EPA, which approved it in October 2015. In 2016, WDEQ’s Air Quality Division approved the Air Quality Permit and re-issued the Air Quality Permit in October 2019.
The NRC issued its Draft Environmental Impact Statement in July 2016, and the final in December of 2016. In its release the NRC noted that “only small environmental impacts would result from the construction, operation, aquifer restoration and decommissioning of the proposed in-situ recovery facility. Small impacts are defined as those that would be undetectable or so minor that they would not noticeably alter any important attribute of the environmental resource in question”. The NRC then issued the License for the project in February 2017 covering 6,057 acres. Subsequently, the NRC approved of the transfer of control to us on July 31, 2017. Additionally, the State of Wyoming became an NRC Agreement state in September 2018 and, therefore, the Reno Creek Project is now permitted and licensed by the WDEQ.
The permits and license provide for a full CPP on 40 acres owned by us, which lies approximately a quarter mile from two all-weather highways and high voltage power lines, and less than three miles from natural gas lines. The project is licensed to produce up to two million pounds of U 3 O 8 per year, and may also treat by tolling either lixiviant or resin produced by others, or alternate feed material. Included in the current license are the two largest resource units, North Reno Creek and Southwest Reno Creek. The outlying resource units will be added for extraction by amending the current Permit to Mine License.

The North Reno Creek Project is situated within and adjacent to our existing permit boundary at the Reno Creek Project, in the Powder River Basin, Campbell County, Wyoming, approximately 80 miles northeast of Casper, Wyoming. We are currently working on a significant revision to the Permit to Mine to incorporate the North Reno Creek Project into the Permit. This permitting action will allow us to mine the resources acquired as part of the transaction.
Substantial historical exploration, development and project permitting have been performed on the North Reno Creek property. Beginning in the late 1960s and continuing into the mid-1980s, Rocky Mountain Energy (“RME”), a wholly owned subsidiary of the Union Pacific Railroad, drilled more than 800 exploration drill holes on the North Reno Creek property. In the late 1970s and early 1980s RME successfully operated and restored and reclaimed a uranium ISR pilot plant. Subsequently, RME nearly completed permitting and licensing for a commercial scale ISR facility.
54
In 1992 the project approximately covering the area of our current Reno Creek and North Reno Creek Project was acquired by EFR from RME. Over the next decade EFR and its successor, International Uranium Corporation (now Denison Mines), continued to advance the project toward full permitting and licensing. Subsequently, Rio Algom and Power Resources held the project until dropping all of their interests in 2003. Between 2006 and 2008 Uranerz acquired mineral and surface land interests covering approximately 1,280 acres of fee mineral leases and federal mining claims comprising the North Reno Creek Project. In June 2015, EFR acquired Uranerz, whose development assets included the North Reno Creek Project.
Geologic characteristics of the North Reno Creek Project are similar to the permitted Reno Creek resource areas since the sandstone units are adjacent and contiguous. The uranium deposits within each of these areas occur in medium to coarse-grained sand facies in the lower portion of the Eocene-age Wasatch Formation. The uranium mineralization occurs as interstitial fillings between and coatings on the sand grains along roll-front trends formed within the host sandstone aquifers.
We engaged Behre Dolbear & Company (USA), Inc. (“Behre Dolbear”) to review and provide a revised Technical Report at the Reno Creek Project integrating the resources present within the North Reno Creek Project acquired on May 1, 2018. A Technical Report, dated December 31, 2018, for the Reno Creek Project, prepared in accordance with NI 43-101, was completed by Behre Dolbear and filed by us on SEDAR.

Canada
Diabase Project
Our Diabase Project is at the exploration stage, with exploration focused on testing the Cable Bay fault corridor, interpreted to represent a suture zone between the Archean Mudjatik and Talston domains within the Trans-Hudson orogeny. Historical work started in the late 1970s, with the first major programs completed by the Saskatchewan Mineral Development Corporation in 1979 and the last major program completed by Nuinsco Resources Inc. (“Nuinsco”) in 2011. There is a total of 67 exploration diamond drill holes on the property. Anomalous uranium values have been intersected on the property, primarily associated with an area intruded by a late diabase dyke, highlighted by drill holes ND0801 (707 ppm Upartial over 0.25 m) and ND0807 (426 ppm Upartial over 0.40 m).
The Diabase Project is located on the southern rim of the Athabasca Basin uranium province in Saskatchewan, Canada, approximately 75 km to the west of Cameco’s Key Lake uranium mill. The project is comprised of 10 mineral claims covering 54,236 acres. Subject to section 19 of The Crown Minerals Act of Saskatchewan , a claim grants to the holder the exclusive right to explore for any Crown minerals that are subject to these regulations within the claim lands. If an economic deposit is discovered, the ore would be extracted by underground methods and would likely be shipped to the Key Lake mill for custom milling.
56
Paraguay
We hold interests in two uranium projects located in the Republic of Paraguay. The following map shows the location of both projects, Oviedo and Yuty.
Oviedo Project
Property Description and Location
Our Oviedo Project is located in southern Paraguay, approximately 95 miles east of Asuncion, the capital of Paraguay. The Oviedo Project consists of a large exploration mining permit covering a total area of 223,749 acres. The property can be classified as an early to intermediate stage exploration project. Several areas have undergone drilling in the past by The Anschutz Company (“Anschutz”) of Denver, Colorado (early 1980s), and recently by Crescent Resources (“Crescent”) in 2007. Access to the project is by paved roads from Asuncion to the City of Coronel Oviedo and other populated areas. There is good access into the interior of the concession mainly by unpaved secondary roads. The terrain is rolling hills with areas of forest, small farms, and some large cattle ranches.
57
Prior Exploration
The Oviedo Project located in central Paraguay was subject to reconnaissance uranium exploration between 1976 and 1983 by Anschutz and by Crescent between 2006 and 2008. Most of the uranium occurrences in this environment are “roll-front” type deposits similar to those currently being produced by low-cost ISR methods in Texas, the western United States, Central Asia and Australia. The work by Anschutz and Crescent was centered on a large belt of Permo-Carboniferous age continental sandstones that represent the western flank of the Paraná Basin. According to the Geological Survey of Brazil or CPRM, these same sandstones within the Brazilian section of the Paraná Basin contain numerous uranium occurrences including the Figueira Mine.
From 2006 to 2008 the Oviedo Project was optioned to Crescent Resources. During this period a total of 24 holes were drilled and logged in the southern portion, offsetting mineralized holes drilled by Anschutz.
A Technical Report, dated October 15, 2012, for the Oviedo Project, prepared in accordance with NI 43-101, was completed by Douglas L. Beahm, P.E., P.G, a consulting geologist/engineer, and filed by us on SEDAR, and the Technical Report reported that 14 of the 24 holes had a GT product (in feet) equal to or greater than 0.30 GT. GT values equal to and above 0.30 are typically considered producible under ISR production methodology. The known uranium mineralization on the Oviedo Project intersected by the past drilling is at depths between 450 and 750 feet. Crescent Resources dropped the option on the Oviedo Project in 2008.
58
Aquifer Test
During 2010, and prior to the acquisition of the Oviedo Project, we conducted a 24-hour aquifer test in the area of the resource trend identified by the combined Anschutz-Crescent drilling programs. The test was designed to assess aquifer properties of the lower massive sand, a uranium-bearing sandstone within the San Miguel Formation. The focus of the test was to determine if the aquifer could sustain extraction rates typical of ISR mining of uranium. Results of the test indicate that the uranium-bearing unit has aquifer characteristics that would support operational rates for ISR mining. The aquifer properties determined from the hydrologic test fall within the range of values determined at other uranium ISR projects located in Wyoming, Texas and Nebraska.
During Fiscal 2012, we completed a 10,000-meter drilling program at the project. A total of 35 holes were drilled, averaging 950 feet in depth. The holes were drilled on east to west lines across known geologic structures believed to be integral in controlling uranium occurrence. The holes were drilled on wide spacings, approximately one to 1.5 miles apart (see map above). Historic and recent drilling results are being reviewed for future exploration/delineation drilling at the Oviedo Project. A radon extraction survey is being completed along the western basin margins, following up on historic airborne radiometric anomalies and outcrop sampling results that indicate a potential for shallow uranium mineralization. Other radon flux monitoring processes were carried out near the town of RI3 Corrales around wells UEC015 and UEC036, which obtained encouraging results that indicate the extension of mineralized levels towards the northeast of these holes.
59
Yuty Project
Property Description and Location
Our Yuty Project covers 289,680 acres and is located approximately 125 miles east and southeast of Asunción, the capital of Paraguay. It is located within the Paraná Basin, which is host to a number of known uranium deposits, including Figueira and Amorinópolis in Brazil. Preliminary studies indicate amenability to extraction by ISR, which is the same process currently used by us at our Texas operations. Cue spent over CA$16 million developing Yuty since 2006.
History
Exploration for uranium in southeastern Paraguay was started in 1976 by Anschutz, after a Concession Agreement was entered into between the Government of Paraguay and Anschutz in December 1975. This agreement allowed Anschutz to explore for all minerals, excluding oil, gas and construction materials. The initial uranium exploration by Anschutz in 1976 covered an exclusive exploration concession of 162,700 square kilometers, virtually the whole eastern half of Paraguay. This was followed by a program of diamond drilling and rotary drilling over selected target areas. In total, some 75,000 meters of drilling were completed from 1976 to1983. Data is available for a total of 257 drill holes in the San Antonio area. Anschutz carried out exploration on behalf of a joint venture with Korea Electric Power Corporation and Taiwan Power Company. Anschutz intersected uranium mineralization in drill holes ranging from 0.115% U 3 O 8 over 10.2 meters to 0.351% U 3 O 8 over 0.3 meters in sandstones and siltstones. Work was suspended in 1983 due to the decline in the price of uranium, and no further work was done at that time.
60
During the exploration programs by Anschutz, airborne radiometric surveys, regional geological mapping and geochemical sampling were the main exploration tools for uranium exploration in the southeastern part of Paraguay. This was followed-up by core and rotary drilling in two phases. The initial phase was to drill wide-spaced reconnaissance diamond drill holes along fences spaced approximately ten miles apart. The objective of this initial phase was to obtain stratigraphic information across an inferred host trend. The second phase was to drill rotary holes, spaced approximately 1,000 feet apart, within and between the fences of reconnaissance holes, to establish and outline target areas. All drill holes were logged and probed by gamma, neutron and resistivity surveys.
Exploration work by Anschutz outlined several large target areas including what is now the Yuty Project. These include the San Antonio, San Miguel, Typychaty and Yarati-í targets near and around the village of Yuty, approximately 125 miles southeast of Asunción.
Geologic Setting and Mineralization
The Yuty Project area is situated within the western part of the Paraná Basin in Southeastern Paraguay, which also hosts the Figueira uranium deposit in Brazil. The area is underlain by Upper Permian-Carboniferous (“UPC”) continental sedimentary rocks. The exploration methodology applied during past programs has been to determine the favorable host rocks of the UPC sequence and to explore favorable areas of the host sandstone.
Continental sedimentary units of the Independencia Formation (of the UPC) are known to have high potential for uranium exploration in eastern Paraguay. The source of the uranium is thought to be the Lower Permian-Carboniferous Coronel Oviedo Formation, which is correlated with the Itataré Formation underlying the Rio Benito Formation in Brazil. Occasional diabase sills and dikes intrude the sedimentary rocks, such as at the San Antonio area near the village of Yuty. Outcrops are rare, mostly along road cuts, and mapping is done by drilling.
The rocks of the Yuty area are very gently east dipping and undeformed. Occasional northwest and northeast trending normal faults cut the sedimentary units. Exploration work to date suggests that the uranium mineralization within the San Miguel Formation is stratabound and possibly syngenetic or diagenetic in origin. Recent interpretation of exploration data suggests that areas of limonite and hematite alteration within the grey-green, fine-grained sandstones in the San Antonio area have characteristics similar to the alteration assemblages present at roll-front type uranium deposits of the Powder River basin in the United States.
61
Geologic Setting of the Yuty Project
Recent Exploration
In late July 2006, Cue signed an agreement with the shareholders of Transandes Paraguay S.A. to option the Yuty property, followed by a formal earn-in agreement signed on November 6, 2007, and started a systematic uranium exploration program. This included a compilation of all previous exploration data, including lithologic and radiometric logs, stored at the MOPC in Asunción. The most recent drilling completed in the San Antonio area was in November and December 2010, at which time 33 holes were completed for a total of 11,500 feet. Of these holes, five were not successfully completed. Of the 28 holes that reached the target, ten had intersections greater than a GT (grade x thickness) of 0.10m% eU 3 O 8 , and an additional 13 had intersections exceeding a GT of 0.03m% eU 3 O 8 .
Drilling and Sampling
Approximately 240,000 feet of drilling (core as well as rotary) were completed by Anschutz in previous campaigns on the Yuty property.
The procedures used during the diamond and rotary drilling programs were drafted by Anschutz technical personnel. Healex reviewed all of the drill logs at the MOPC in Asunción and was of the opinion that the lithologic logging procedures are comparable to industry standards. Detailed information on sampling methods and approach during the Anschutz drilling campaigns is not available. Nevertheless, previous technical reports (Scott Wilson (2008) and Healex (2009)) have concluded that sampling procedures were comparable to industry standards of that time. Mr. Beahm (2011 technical report) concurs with this determination. From 2007 to 2010, Cue completed over 100,000 feet of drilling at the San Antonio target area in 256 drill holes. Most of the holes were collared with a rotary drilling rig, surface casing was then installed, and the holes were drilled to completion depth with a diamond rig. To date, diamond drilling totals approximately 52,800 feet and rotary drilling approximately 50,000 feet. For diamond drill holes, HQ-size core was retrieved and the drilling contractor was Empire Drilling S.A. of Quito, Ecuador. For rotary drilling, the contractor was 9 de Junio S.A. (Primo) of Asunción, Paraguay.
62
Exploration Potential
Except for the San Antonio area, the Yuty Project is at an early-to intermediate stage of exploration. A number of areas of anomalous concentrations of uranium occur in UPC sedimentary rocks within the property area. Past work was focused on developing roll-front type targets. Preliminary interpretation of the drill results in the San Antonio area suggests that the basal sandstone unit (San Miguel Formation) is a favorable host for uranium mineralization. These results also suggest that the diabase sill overlying the San Miguel Formation may have acted as a trap for diagenetic fluids and provided a horizontal conduit for the circulation of the diagenetic fluids and emplacement of uranium mineralization near the margin of a topographic high (gentle hill) below the diabase sill.
Historic and recent drilling results are being reviewed by our Company for future exploration/delineation drilling at the Yuty Project.
A Technical Report, dated August 24, 2011, for the Yuty Project, prepared in accordance with NI 43-101, was completed by Douglas Beahm, P.G., P.E., Bill Northrup and Andre Deiss, consulting geologists, and filed by us on SEDAR.
In April 2015 the Yuty Project received a signed resolution from the MOPC, the national agency that regulates mining in Paraguay, advancing the project from the Exploration Phase into the Exploitation Phase. The Yuty Project is only the third mining project to achieve the Exploitation Phase since the current Paraguayan mining law was promulgated in 2007.
When the MOPC grants a mineral concession to an operator the project initially enters the Exploration Phase for a maximum of six years, during which period a company must advance and demonstrate a viable project. The Exploration Phase is followed by the Exploitation Phase for a maximum of 20 years renewable every five years indefinitely, during which period the environmental licensing process may begin, a key milestone required before starting production, as well as allowing for reductions in land and various investment costs. The Exploitation Phase is followed by the Production Phase which lasts for an indefinite period.
Alto Paran á Titanium Project
We acquired our Alto Paraná Titanium Project from CIC Resources Inc. (“CIC”) on July 7, 2017 .
Property Description and Location
The Alto Paraná Titanium Project is a titanium project located in Eastern Paraguay in the Alto Paraná province approximately 100 km north of Ciudad del Este and consists of 174,200 acres. The Alto Paraná Project resource is atypically high in titanium values when compared to most beach sand deposits. High iron laterite hosts heavy minerals containing high iron and titanium values as ilmenite, titanomagnetite and magnetite.
63
History
Exploration work on the property was initiated by CIC in 2009 with a program of widespread hand-dug pits consisting of channel samples at approximately one-meter vertical intervals within the laterite. The initial phase of pitting and sampling was followed up by more closely spaced deep pitting and shallow (one m) auger drilling in 2010 and 2011. In total, 4,432 samples from deep pits and 2,992 one-meter auger samples have been collected and analyzed. The purpose of the exploration work was to evaluate the original CIC hectares to determine the area of best grade and thickness. Based on these extensive sampling efforts, we now control this generally higher-grade/thickness area as previously noted.
CIC also conducted extensive process development work with the objective of a viable process flow sheet for beneficiation of the heavy minerals from the laterite. This work was carried out by Mineral Advisory Group, and included design, construction and operation of a 1.5 tonne per hour pilot plant in Paraguay. During operations the plant underwent continual process improvements and eventually produced 108 tonnes of concentrate over a three-month period. In January 2012 the concentrate was shipped to MINTEK in South Africa for smelting in a MINTEK pilot plant.
Geologic Setting and Mineralization
Mineralization on the property consists of laterite containing ilmenite, titanomagnetite and magnetite derived from Early Cretaceous tholeitic basalts of the Paraná Basin and associated gabbro intrusions. The basalts and gabbros have been weathered to laterite to an average depth of approximately seven metres over a very extensive area. Kaolinite is the dominant mineral, representing 60% to 75% of the mineral assemblage. Ilmenite, magnetite and titanomagnetite are present in the laterite as discrete minerals ranging in particle size from <40 µm to 350 µm with average particle sizes in the 135 μm to 165 μm range. The grade of titanium in the laterite ranges up to approximately 11% but is typically in the 5% to 9% range.
64
Summary
The Alto Paraná Titanium Project appears to be homogeneous and much higher grade than existing mineral sands deposits. Further work on particle size distribution of the ilmenite/titanomagnetite fractions and variable laterite bulk density as a function of depth will help better define the Alto Paraná Titanium Project.
On September 12, 2017, we filed a NI 43-101 Technical Report for the Alto Paraná Project authored by Martin C. Kuhn, PhD, PE and David M. Brown, P. Geo., and filed it on SEDAR.
The Company has had communications and filings with the MOPC, whereby the MOPC is taking the position that certain concessions forming part of the Company’s Yuty Project and Alto Paraná Project are not eligible for extension as to exploration or continuation to exploitation in their current stages. While we remain fully committed to our development path forward in Paraguay, we have filed certain applications and appeals in Paraguay to reverse the MOPC’s position in order to protect the Company’s continuing rights in those concessions.

South Texas Goliad Project
Our South Texas Goliad database includes raw and interpreted data compiled by Total Minerals (“TOMIN”) and others from the mid-1980s to 1993. The database is an evaluation of the uranium potential within the Goliad Formation from south of Houston to the Mexican border.
Through TOMIN’s purchase of the Holiday-El Mesquite project, located in Duval County, Texas, in 1990, TOMIN acquired the Mobil uranium exploration database. Starting with this data, and earlier data purchased from Tenneco Uranium, TOMIN also acquired regional oil and gas logs (included in the database), water well driller logs and other regional information to begin their study of the Goliad Formation along the South Texas Uranium Belt.
67
As a result of the study TOMIN identified 62 targets and drilled 22 holes by project end in 1993. Of the 22 drilled, 19 were disproved and the remaining three await further drilling to assess trends. Another 40 targets remain to be drill-evaluated.
In summary, the database contains:
●
4,894 South Texas uranium logs - 2.8 million feet of drilling;
●
13,882 South Texas oil and gas logs - 41.6 million feet;
●
752 maps/sections across South Texas; and
●
103 documents, reports and analyses documenting the study.
