Azarga Uranium Corp. has identified additional uranium mineralization at its initial development priority, the Dewey Burdock in situ recovery (ISR) uranium project in South Dakota. The company has identified this mineralization through its continued analysis of historical data owned by the company and the evaluation of revised ISR cut-off criteria, consistent with other producing ISR projects in nearby Wyoming.
Highlights of the additional uranium mineralization at the Dewey Burdock project include:
- 107 mineralized drill holes with 111 intercepts equal to or exceeding a 0.2 grade thickness (GT) cut-off using a 0.02-per-cent grade cut-off with an average eU308 (triuranium octoxide equivalent) grade of 0.105 per cent and an average thickness of 5.5 feet:
- 26 per cent of the mineralized drill holes exceed a 0.5 GT cut-off;
- Falls within the existing Nuclear Regulatory Commission (NRC) licence boundary for the Dewey Burdock project;
- Contiguous with ISR amenable resources already identified at the Dewey Burdock project;
- Provides further indication that the resource trends head west toward the company’s Dewey Terrace project;
- Indicates the potential expansion of the Dewey Burdock project resource to the north and the south within the NRC licence boundary.
“We are very excited that our analysis of the data set and the evaluation of revised ISR cut-off criteria has identified additional uranium mineralization at the Dewey Burdock project. The newly identified uranium mineralization indicates the potential to increase uranium resources at the Dewey Burdock project. Further, to this point, the analysis of the data set and the revised ISR cut-off criteria has only focused on the Dewey area of the project, which represents approximately 40 per cent of the current resource estimate. As we continue our review of the data set, we expect that further uranium mineralization will be identified at the Burdock area of the project. Additionally, the Burdock area of the project contains substantially more historical drilling than the Dewey area,” said John Mays, chief operating officer.
The associated table provides a detailed summary of the results for the 107 mineralized drill holes with 111 intercepts that equal or exceed a 0.2 GT cut-off using a 0.02-per-cent grade cut-off.

The technical information in this news release has been prepared in accordance with the Canadian regulatory requirements set out in National Instrument 43-101 and was reviewed by Mr. Mays, a qualified person under NI 43-101.
The data set includes historical drilling information that has been reviewed by the company’s geological team, as well as 91 exploratory drill holes completed by the company in a previous exploration campaign. The company’s review of the records and information within the data set reasonably substantiate the validity of this information; however, the company cannot directly verify the accuracy of the historical data, including the procedures used for sample collection and analysis. Therefore, the company encourages investors not to place undue weight on these results.
The company’s current resource estimate and preliminary economic assessment dated April 21, 2015, with an effective date of Jan. 29, 2015, for the Dewey Burdock project use a cut-off grade of 0.05 per cent and GT of 0.5; whereas, the intercepts identified above utilize a cut-off grade of 0.02 per cent eU3O8 and GT of 0.2, which is consistent with other producing ISR projects in nearby Wyoming.
