Azarga Uranium CORP. (TSX:AZZ)(OTCQB:AZZUF)(FSE:P8AA) ("Azarga Uranium" or the "Company") has filed a technical report supporting the National Instrument 43-101 ("NI 43-101") resource estimate for its Gas Hills Uranium Project in Wyoming (the "Gas Hills Project") announced on 30 March 2021. The Company has also engaged WWC Engineering and Roughstock Mining Services, LLC ("Roughstock") to complete a preliminary economic assessment on the back of the increased resource estimate

Highlights:

• Measured and Indicated uranium resources increased to 10.77 million pounds U₃O₈ from 4.73 million pounds U₃O₈ (128% increase)
• Measured and Indicated ISR uranium resources total 7.71 million pounds U₃O₈ (72% of overall Measured and Indicated resources)
  • Average U₃O₈ grade of 0.101%
• Maiden ISR resource estimate achieves significant grade and scale and supports further advancement of the project
• Preliminary economic assessment underway; strong potential for Gas Hills Project to become a significant satellite deposit to our flagship Dewey Burdock Project

Updated Mineral Resource Estimate - 29 March 2021

Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability.

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 0.10 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.

In addition, ISR resources that fall within the 0.20 GT contour have also been estimated in the table below (all other calculation criteria are the same as noted above):
