Azarga Reports Robust PEA Results for Dewey Burdock Project






AZARGA URANIUM CORP. (TSX:AZZ) (OTCQB:AZZUF) (FRA:P8AA) is pleased to announce the positive results of an independent Preliminary Economic Assessment on its flagship Dewey Burdock In-situ Recovery Uranium Project in South Dakota, USA following an updated mineral resource estimate. The PEA has been prepared in accordance with the requirements of National Instrument 43-101.


Blake Steele, the Company’s President and CEO commented: “We are extremely pleased with the results of the updated PEA for the Dewey Burdock Project. The PEA demonstrates robust economics and cements the Dewey Burdock Project as one of the preeminent undeveloped in-situ recovery projects in the United States. The PEA results further validate our Company’s strategy and we continue to progress the project towards construction as the global uranium market strengthens by virtue of supplier discipline and higher demand. The estimated cost profile and modest initial capital expenditures leave Dewey Burdock and the Company well positioned to capitalize on the anticipated recovery in the uranium price.”


Summary of Economics


The base case economic assessment results in a pre-income tax internal rate of return of 55% and a pre-income tax net present value 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. 0.02 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.


The Dewey Burdock Project PEA has been prepared in accordance with the requirements of NI 43-101 and was prepared by TREC, Inc. Douglass Graves, P.E., a qualified person as defined under NI 43-101, and Roughstock Mining Services, Steve Cutler, P.G., QP. The full technical report and PEA will be filed on SEDAR at and Azarga Uranium’s website within 45 days of the issuance of this news release.


Project Description


The Dewey Burdock Project is an advanced-stage uranium project located in South Dakota, USA. The Company has received its Nuclear Regulatory Commission License, which has one remaining contention outstanding, and its draft Class III and Class V Underground Injection Control permits from the Environmental Protection Agency. The Company looks forward to the Atomic Safety and Licensing Board decision on the final remaining NRC License contention for the Dewey Burdock Project, which is now expected on 16 December 2019.


The Dewey Burdock uranium mineralization is comprised of “roll-front” type uranium mineralization hosted in several sandstone stratigraphic horizons that are hydro-geologically isolated and therefore amenable to ISR mining methods. The Dewey Burdock Project is located in a region where ISR projects have been and are operated successfully. The ISR mining method has been proven effective in geologic formations near the Dewey Burdock Project in Wyoming and Nebraska.


The Dewey Burdock Project consists of two resource areas: the Burdock resource area and the Dewey resource area. The central processing plant for the Dewey Burdock Project will be located at the Burdock resource. A satellite facility will be constructed at the Dewey resource area.


The Dewey Burdock Project PEA contemplates a phased development approach. The Burdock CPP will be constructed to initially accept a flow rate of up to 1,000 gallons per minute of lixiviant solution. Capacity will gradually be expanded to accept a flow rate of 4,000 GPM of lixiviant solution.


Similarly, ion exchange capacity will gradually be increased. During the first few years of operation, resin will be transferred from IX vessels to resin trailers to be transported and processed at an off-site processing facility. Once the CPP flow rate capacity has reached 4,000 GPM, the Burdock CPP will be expanded to include processing capabilities for approximately one million pounds per annum of U3O8.


First production occurs after year one of construction, with approximately 126,000 pounds of U3O8 being produced. The production ramp-up continues until reaching a steady-state production level of approximately 1 million pounds of U3O8 two years later, in the third year after construction commences. Restoration and surface reclamation will also be implemented concurrently with production and will continue approximately four years beyond the production period. The overall mine life will be approximately 21 years from initiating construction to completing decommissioning.


Data Verification


An overall assessment of the data used for the classification of resources into various categories is required by the CIM Definition Standards. This assessment showed that historical data gathering and interpretation of the data was conducted by a well-respected, major uranium exploration company with high-quality uranium exploration staff. It also showed that at key points, professional geologic consultants reviewed and verified the results of the historic exploration programs. Numerous academic reports have also been published on geologic settings and uranium mineralization of the Dewey Burdock Project.


Interpretive geologic evaluation has also been completed under the direction of the Company’s senior geologic staff. All these factors provide a high level of confidence in the geological information available on the mineral deposit and that historic drillhole data on the Dewey Burdock Project is accurate and useable for continued evaluation of the project.


The QP (Mr. Cutler) notes that the drilling conducted by Azarga Uranium has verified the location and grade of uranium mineralization in the updated resource estimate. There are no known discrepancies in locations, depths, thicknesses, or grades that would render the project data questionable. The QP has adequately verified the historical data for the Dewey Burdock project. The QP has reviewed the data confirmation procedures and concludes that the drillhole database has been sufficiently verified and is adequate for use in resource estimation. The QP concludes the work done by Azarga Uranium to verify the historical records has validated the project information in the updated resource estimate.
