Solitaire Minerals Corp. Options Three Properties Bordering the Recent Denison Mines

July 21, 2009: Solitaire Minerals Corp. (TSX-V symbol: SLT) (the "Company") would like to announce that it has entered into an Option Agreement whereby Delta Uranium Inc. (Delta) has the potential to earn up to a 75% interest in the 447 hectare Block C4, the 1,016 hectare Block C5, and the 161 hectare Block C6 properties which are all contiguous with Denison Mines recent "Phoenix" discovery zone in the south-eastern part of the Athabasca Basin. This Option Agreement is subject to TSX Exchange approval.

Block C3 (recently optioned to Delta - SLT news dated May 27, 2009) and Blocks C4-C6 lie within the same NE-SW trending magnetic lows, characteristic of the Wollaston Domain metasedimentary/metapelltic basement and are considered prospective for unconformity and basement hosted uranium deposits. All Blocks were flown with VTEM in 2007 and interpreted by Condor Consulting. All four Blocks (C3-C6) exhibited "Priority 1" EM anomalies and are recommended for further work. For a geophysical map of the area indicating the location of Blocks C1-6 in relation to Denison Mines "Phoenix" discovery zone please visit the following link http://www.solitaireminerals.com/projects/cdblocks/.

The "Phoenix" discovery zone located approximately 1km south of the Wheeler River C6 Project host a six meter intercept of massive pitchblende showing a grade of 55% eU3O8 in WR-273 with other significant intercepts of note in WR-274 (3.0 meter interval of 16.9% eU3O8) and WR-272 (2.1 meter interval of 6.75% eU3O8) all at depths of approximately 400 meters. This is the first time intense alteration of this type has been encountered in the basement rocks along the Phoenix mineralized trend (please refer to the June 30, 2009 release by Denison Mines Corp.).
