Azarga Uranium Reports Robust Maiden PEA Results for Gas Hills ISR Uranium Project


  • Pre-income tax IRR of 116% and NPV of US$120.9 million
  • Post-income tax IRR of 101% and NPV of US$102.6 million
  • 6.5 million pounds of U3O8 production over 7 years; steady state production of 1.0 million pounds per year
  • Robust satellite project to Azarga Uranium's flagship Dewey Burdock ISR Uranium Project with low initial capital expenditures estimated at US$26.0 million
  • Direct cash operating costs estimated at US$11.52 per pound of production

Azarga Uranium CORP. (TSX:AZZ)(OTCQB:AZZUF)(FRA:P8AA) ("Azarga Uranium" or the "Company") is pleased to announce the positive results of an independent Preliminary Economic Assessment(" PEA") on its Gas Hills In-situ Recovery Uranium Project in Wyoming, USA (the "Gas Hills Project") following an increased mineral resource estimate announced by the Company on 30 March 2021. The PEA has been prepared in accordance with the requirements of National Instrument 43-101 ("NI 43-101

Blake Steele, the Company's President and CEO commented: "We are extremely pleased with the results of our maiden in-situ recovery ("ISR") PEA for the Gas Hills Project. The PEA demonstrates robust economics and expands the future production profile of the Company into the state of Wyoming, which has a long history of successful ISR operations. The PEA results further validate our Company's strategy of developing low-cost ISR projects as we continue to progress our flagship Dewey Burdock Project towards construction. With uranium markets in a structural deficit, Azarga Uranium is exceptionally well positioned to capitalize on the anticipated recovery in the uranium price through its two tier one development stage ISR uranium projects in the USA."

Summary of Economics

The base case economic assessment results in a pre-income tax internal rate of return ("IRR") of 116% and a pre-income tax net present value ("NPV") of US$120.9 million when applying an eight percent discount rate. Using the same discount rate, the post-income tax IRR is 101% and the post-income tax NPV is US$102.6 million.

The projected cash flows for the Gas Hills Project PEA are positive in the 1st year of production, two years after the commencement of construction. Initial capital expenditures are estimated at US$26.0 million.

Direct cash operating costs are estimated to be US$11.52 per pound of production, royalties and local taxes are estimated to be US$3.62 per pound of production and the total pre-income tax cost of uranium production is estimated to be US$28.20 per pound of production. Income taxes are estimated to be US$3.82 per pound of production and have been calculated on a project basis in accordance with NI 43-101 requirements; therefore, certain tax shelter balances, such as tax loss carry forwards available at the corporate level, have not been considered.

Cautionary statement: The results of the Gas Hills Project PEA are preliminary in nature and include inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. The Gas Hills Project PEA is based on the Company's mineral resource estimate announced on 30 March 2021. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimated mineral recovery (80%) used in the Gas Hills Project PEA is based on site-specific laboratory recovery data and industry experience at similar facilities. There can be no assurance that recovery at this level will be achieved. There is no certainty that the Gas Hills Project PEA will be realized.

Project Description

Between 1953 and 1988 many companies explored, developed, and produced uranium in the Gas Hills district, including on lands now controlled by Azarga Uranium. Three uranium mills have operated in the district and two other uranium mills, which operated nearby, were also fed by ore mined from the Gas Hills district. Cumulative production from the Gas Hills district is in excess of 100 million pounds of uranium, mainly from open-pit mining, but also from underground mining and ISR.

Data sources for the estimation of uranium mineral resources for the Gas Hills Project include radiometric equivalent data (eU3O8) for 4,569 drill holes, and eU3O8 and prompt fission neutron logging data for 272 drill holes. The intent of recent drilling between 2007 and 2013 included verification of earlier data for drill holes and exploration.

Metallurgical studies were completed on recovered materials including bulk samples from reverse circulation drilling and cored sections. Bottle roll and column leach tests indicate uranium recoveries of ~90% and sulfuric acid consumption of ~55 pounds per ton treated, which is consistent with past mining results.

The Gas Hills Project PEA contemplates a satellite plant development approach with final processing at a central processing facility to be constructed at Azarga Uranium's Dewey Burdock Project. Construction of the Gas Hills Project will consist primarily of wellfields in four separate resource areas connected by pipelines to a single satellite plant location containing ion exchange equipment used to extract uranium from produced wellfield fluids. Ion exchange resin will be shipped from the Gas Hills Project to the Dewey Burdock Project for uranium stripping and regeneration, with creation of a dried yellowcake product at Dewey Burdock. This concept has been used successfully for decades in numerous ISR uranium operations in Texas and Wyoming. Wellfield extraction methods will utilize a low-pH complexing solution consistent with other successfully licensed ISR uranium facilities in Wyoming and worldwide. Average project flow rate is estimated at 2,400 gallons per minute with an average head grade of 97 parts per million for an annual production capacity of 1.0 million pounds U3O8.

Biden Signs Bill Banning Russian Uranium Imports, Restrictions to Begin in 90 Days

US President Joe Biden signed the Prohibiting Russian Uranium Imports Act into law on Monday (May 13), effectively starting the process of ending US dependence on imported uranium supply.

“This new law reestablishes America’s leadership in the nuclear sector. It will help secure our energy sector for generations to come,” said National Security Advisor Jake Sullivan in a White House statement.

“And — building off the unprecedented US$2.72 billion in federal funding that Congress recently appropriated at the President’s request — it will jumpstart new enrichment capacity in the United States and send a clear message to industry that we are committed to long-term growth in our nuclear sector,” he continued.
