Solitaire's Partner Terra Ventures Inc. Commences Drilling on Uranium Properties Adjoining Denison's Phoenix High-Grade Uranium Discovery, Athabasca Basin

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 22, 2011) - Solitaire Minerals Corp. (TSX VENTURE:SLT) (Solitaire) reports that Terra Ventures Inc. (TSX VENTURE:TAS) ("Terra") has commenced a diamond drilling programs on the Wheeler River uranium properties, adjoining the Denison Mines property and the Phoenix Zone, in the Athabasca Basin of Saskatchewan.

Terra has the option to earn up to a 95% interest in three dispositions, from Solitaire, known as C-4, C-5 and C-6, with an aggregate area of 4,011 acres (1,624 hectares) adjoining the northwest side of the Wheeler River property of Denison Mines Corp. (TSX:DML) (60 percent), Cameco Corp. (TSX:CCO) (30 percent) and JCU (Canada) Exploration Co. (10 percent). Denison has announced an indicated mineral resource for its Phoenix Zone of 35.6 million pounds of U3O8, with a grade of 18.0% U3O8. The Phoenix B Zone has an additional inferred resource of 3.8 million pounds grading 7.3% U3O8. Denisons' summer drill program begins in early June and will involve the drilling of approximately 55 holes for 24,000 metres.

The highlights of the properties are:

  • Property lies midway between the McArthur River mine and the former producing Key Lake mine;
  • Several conductors defined by previous airborne EM surveys;
  • Extensive clay alteration found in boulder sampling;
  • Uranium and pathfinder element geochemical anomalies in boulder sampling;
  • Quartzite ridge in basement rocks was defined by previous diamond drilling on the C-5 property; similar quartzite ridges at the Phoenix Zone and the McArthur River mine are believed to localize uranium deposition;

The three properties lie on a structural corridor located along a belt of Aphebian metasediments in the subAthabasca basement. Previous airborne EM surveys have defined conductors on the C-4 and C-5 blocks. Previous drilling in the area has resulted in the recognition of a broad zone of clay alteration of the type that is always associated with unconformity-type uranium mineralization in the Athabasca basin. There is also evidence from prior drilling that a quartzite ridge in the basement, similar to that which appears to be at least partially responsible for localizing the giant McArthur River orebody and the Phoenix zones, is present on the C-5 block.

The McArthur River uranium mine owned by Cameco (70 per cent) and AREVA Resources Canada (30 per cent) is mining an orebody with estimated proven and probable reserves of approximately 334 million pounds of U3O8 grading 19.53% U3O8, a measured and indicated resource of 30 million pounds of U3O8, an inferred resource of 159 million pounds of U3O8, and past production of 171.2 million pounds of U3O8 (Cameco 2009 annual report). This uranium deposit (approximate size of 700 million pounds of U3O8) is the world's largest high-grade uranium mine.

Terms of Option Agreement

Upon regulatory approval, Terra has already paid $100,000 and issued 100,000 shares to Solitaire. In order to acquire an initial 55% interest, on or before December 31, 2011 Terra must pay Solitaire an additional $100,000, issue an additional 50,000 shares and incur at least $1,000,000 in exploration expenditures on the properties. Upon the exercise of this initial option, Terra will have the right to increase its interest to 75% on or before December 31, 2012 by paying an additional $150,000, issuing an additional 50,000 shares and incurring an additional $1,000,000 in expenditures. For a period of five years after the exercise of this second option, Terra may increase its interest to 95% by paying Solitaire $5,000,000, whereupon Solitaire's remaining 5% interest will be converted into a production carried interest.

Terra currently holds a 2% Net Smelter Returns Royalty on the properties.
