Azarga Uranium Files Robust PEA for Dewey Burdock Project

January 17, 2020 11:30 am

AZARGA URANIUM CORP. (TSX: AZZ, OTCQB: AZZUF, FRA: P8AA) (“Azarga Uranium” or the “Company”) has filed its National Instrument 43-101 (“NI 43-101”) Technical Report and Preliminary Economic Assessment (“PEA”) for its flagship Dewey Burdock In-situ Recovery (“ISR”) Uranium Project in South Dakota, USA (the “Dewey Burdock Project”) following the Company’s press release dated 4 December 2019.


  • Pre-income tax IRR of 55% and NPV of US$171.3 million (at US$55 per pound uranium sales price and 8% discount rate)
  • Post-income tax IRR of 50% and NPV of US$147.5 million (at US$55 per pound uranium sales price and 8% discount rate)
  • 14.3 million pounds of U3O8 production over 16 years; steady state production of approximately 1 million pounds per year achieved in year 
  • Low initial capital expenditures estimated at US$31.7 million
  • Direct cash operating costs estimated at US$10.46 per pound of production

Summary of Economics

The base case economic assessment results in a pre-income tax internal rate of return (“IRR”) of 55% and a pre-income tax net present value (“NPV”) of US$171.3 million when applying an eight percent discount rate.  Using the same discount rate, the post-income tax IRR is 50% and the post-income tax NPV is US$147.5 million.

The projected cash flows for the Dewey Burdock Project PEA are positive in the second year of production, two years after the commencement of construction. Initial capital expenditures are estimated at US$31.7 million.

Direct cash operating costs are estimated to be US$10.46 per pound of production, royalties and local taxes (excluding property tax) are estimated to be US$5.15 per pound of production and the total pre-income tax cost of uranium production is estimated to be US$28.88 per pound of production.  Income taxes are estimated to be US$3.39 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 Dewey Burdock Project PEA are preliminary in nature and includes 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.  Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimated mineral recovery used in the Dewey Burdock Project PEA is based on site-specific laboratory recovery data as well as Azarga Uranium personnel 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 Dewey Burdock Project PEA will be realized.

Updated Mineral Resource Estimate – 3 December 20191

Dewey Burdock Project ISR Mineral Resource Estimate
Measured Resources Indicated Resources Measured plus Indicated Resources Inferred Resources
Tons 5,419,779 1,968,443 7,388,222 645,546
Average grade (% U3O8) 0.132 0.072 0.116 0.055
Average thickness (feet) 5.56 5.74 5.65 5.87
Average grade-thickness (“GT”) 0.733 0.413 0.655 0.324
Uranium (pounds) 14,285,988 2,836,159 17,122,147 712,624
    1. Mineral resources that are not mineral reserves do not have demonstrated economic viability.


In addition to the ISR mineral resource estimate, the NI 43-101 resource estimate includes a non-ISR (located above the water table) resource estimate containing Measured resources of 857,186 pounds at 0.060% U3O8, Indicated resources of 407,851 pounds at 0.053% U3O8 and inferred resources of 114,858 pounds at 0.051% U3O8. These resources are not included in the ISR resources presented in the table above and are not included in the economic analysis for the Dewey Burdock Project PEA. 

Both the ISR and non-ISR resources were determined using the GT contour method and met the following criteria:

    1. 02 percent grade cutoff;
    2. Occur within the same mineral horizon (roll front);
    3. Fall within the 0.20 GT contour; and
    4. Extend no farther from the drill hole than the radius of influence specified for each category, i.e., measured, indicated or inferred.

For the purpose of the PEA, the uranium recovery is estimated at 80% for all categories of ISR resources. Therefore, life of mine U3O8 production is estimated to be 14.3 million pounds.
