Sagar Property

The Sagar Property is the Company's primary exploration focus as it possesses exceptional grades for both uranium and gold. The Mistamisk Boulder Field is approximately 500 X 250 meters in size and contains many radioactive boulders. In a Virginia Mines report, 70 boulders assayed an average of 64.9 g/t Au and 1.3% U (with values up to 640 g/t Au and 16.5% U). Uranium Star is the direct beneficiary of the extensive exploration efforts incurred by previous operators including Virginia. These programs have shown that the Sagar Property is characterized by an impressive amount of uranium, gold, copper and lead/zinc mineralization of different styles and potential deposit models.
