December 3, 2004: Solitaire Minerals Corp. (the Company) has received the results of the recently completed diamond drilling program on the Company's 100% optioned Union Mine Property, located near Grand Forks, British Columbia.

A seven hole, 5391 foot (1643 m) diamond drill program has been completed on the Union property. A total of 178 drill core samples were collected and shipped to Eco Tech Laboratories in Kamloops, BC for analyses. Quality control measures were employed, including company inserted standards and blanks. Analytical results have now been received for all of the drill holes.

Drilling was done on four separate targets. Holes 04-1 to 04-4 were drilled at the West Union target, in an attempt to locate the western faulted offset of the Union Vein, west of the Maple Leaf fault and beneath post-mineral sedimentary cover. Drilling in this area is hindered by the very steep topography, which physically limits where the drill can be set up, and by poor ground conditions associated with the Eocene unconformity. Hole 04-3 did intersect a zone of intense silicification/veining from 255.12 - 257.62 meters in the drill hole. This zone is sparsely mineralized with pyrite and is visually similar to portions of the Union vein exposed in old workings to the east. Gold and silver values were only slightly elevated within the zone, to 135 ppb Au and 3.7 ppm Ag. Drill hole 04-4 was drilled to test the silicified zone at a point approximately 65 meters higher in elevation. The zone was intersected at a very low core angle and was much narrower than in hole 04-3, with no elevated gold or silver values.

Hole 04-5 was drilled to test the Maple Leaf Crush Zone at a depth of 180 meters vertically below surface, to test for a possible vertical zonation in gold within the zone. The “crush zone” had a true width of about 14.5 meters where intersected in hole 04-5, but was only weakly mineralized with pyrite. There were no elevated gold and silver values.

Hole 04-6 tested a strong north-trending EM conductor along Gloucester Creek, in an area that could not be explored by trenching because of deep overburden cover. The EM conductor was attributed to black graphitic shale in Eocene sediments. There was no significant mineralization in the hole.

The final drill hole, hole 04-7, tested the White Bear epithermal zone at depth. Trenching had exposed a strong north-trending silicified zone in Eocene sediments which had returned weakly elevated gold values. Hole 04-7 was drilled to test for the possibility of a vertical zonation to gold and silver within the zone and was designed to intersect the zone at a vertical depth of about 130 meters below surface. The hole intersected a series of narrow quartz veins and zones of argillic alteration, intermittently over a total zone width of about 50 meters. Samples failed to return any elevated values of gold or silver.

Charles Desjardins, President of Solitaire Minerals Corp. states, “Though we are disappointed with the results, we know negative results are part of mineral exploration. However, the Company will continue its exploration efforts and looks forward to 2005.”

This program is under the supervision of independent consulting geologist Linda Caron, M.Sc., P.Eng, a qualified person as defined by National Instrument 43-101.

Athabsca Basin Properties Mr. Jim Kermeen, M.Sc., P.Eng, the Company's Uranium advisor, is presently analysing data from his recent trips to Saskatchewan, that will allow us to plan our up coming uranium exploration programs. We anticipate our programs to start in February of 2005.

Red Lake Properties Terraquest Ltd. of Toronto, Ontario is conducting an aero-mag survey on the South Baird and Heyson properties. The work program will entail a 118 Lkm airborne geophysical survey with qualitative interpretation by Dr. Allan Spector of Allan Spector & Associates Ltd, of Toronto, Ontario.

In other news, Solitaire Minerals Corp. annual general meeting was held on November 26, 2004. All resolutions and business items presented at the meeting were approved.

The Union Mine Property. The Union Mine Property consists of approximately 1,500 acres located in the Franklin Mining Camp, roughly 60 kms north of Grand Forks. The regional area of this part of the province is locally referred to as the Boundary district and encompasses the Rossland Camp on the east (produced over 3,500,000 oz of silver and over 2,700,000 oz of gold), the Republic area on the south, Buckhorn Mountain on the west and the Union Mine to the north. The Boundary District has a number of historical production areas and several current unmined reserves, including Buckhorn Mountain and Emanuel Creek (in production since December 2003). The Union Mine property is accessible via good quality all-weather road, and contains extensive underground workings. Historical production from a series of ore bearing veins was carried out between 1913 and 1989, with the majority of production occurring prior to 1942.

The above data is referenced in the 2004 technical and recommendations report on the Union Property, written by Linda Caron, M.Sc., P.Eng. The report is compliant with National Instrument 43-101. To view the report in its entirety please visit www.sedar.com
