Enters into Option Agreements with Rubicon Minerals Corp. on Two Properties in Red Lake, Ontario April 20, 2006: Solitaire Minerals Corp. (TSX-V symbol: SLT) (the "Company") is pleased to announce that it has entered into two option agreements with Rubicon Minerals Corp. (TSX-V symbol: RMX) on the Red Lake North property and the Humlin property. These agreements allow the Company to approximately triple its land holdings in the Red Lake area by earning 55% ownership, after honoring a four year work commitment, on each of the Red Lake North and the Humlin projects. Red Lake North Agreement The Red Lake North property is located approximately 22 km northeast of Red Lake, Ontario, in the prolific Red Lake Mining District. The property consists of forty seven staked mining claims totaling 329 units (approximately 5264 Ha). The property is 30 minutes by logging road from the Town of Red Lake, which is the business and government centre for the region. The area has a rich mining history, with two active producing mines (the Campbell and Red Lake Mines), and has all the facilities and infrastructure required to develop a new mining operation. The Red Lake North property is separated into two distinct packages of ground. The larger of the two blocks is located on the northwest margin of the Black Bear Intrusive. Geologically, the property is dominated by a package of Balmer assemblage mafic and ultramafic volcanic rocks which are overlain by altered intermediate sediments. The stratigraphic units are interpreted to be upright and dipping at 60 to 70 degrees to the northwest. A series of northwest trending, vertical to subvertical faults crosscut and offset stratigraphy. This property is directly along strike from the recent ‘Planet Zone’ Au discovery, currently being explored by Goldcorp/Planet (TSX-V symbol: PXI). Based on historical drilling and geophysical interpretation on this land package, the extension of Au bearing sericite schist that is observed on the Planet Zone continues southwest onto the newly acquired property. The prospective sericite schist target horizon is interpreted to occur at depth and along the entire 12km strike length of the property. All three holes drilled by Rubicon intersected the prospective sericite schist altered horizon. The smaller of the two blocks is situated on the up-dip and down-dip extensions of the recent Goldcorp/Planet Au discovery. Geologically, the property is dominated by a package of Balmer assemblage mafic and ultramafic volcanic rocks which are overlain by altered intermediate sediments. The southeastern claim block is on the contact between the overlying Balmer Assemblage volcanics and the Cat Island Pluton to southeast. Based on drilling by RMX, the prospective Au bearing sericite schist horizon continues onto the northwestern claim block, at depth. To date, only two holes have been drilled on this claim block. Further drilling is required to test for the continuity and controls of Au mineralization on the property.

Transfer 50,000 shares to Rubicon Minerals Corp. $275,000 work in first year (2006) $400,000 work in second year (2007) $575,000 work in third year (2008) $1,250,000 work in fourth year (2009) For a total of $2,500,000 Humlin Agreement The Humlin property is located 10 km northwest of Red Lake, Ontario, in the prolific Red Lake Mining District. The property consist of thirty-one staked mining claims totaling 294 units (approximately 4700 Ha).The property is accessible via watercraft in summer, ice roads in winter, and locally via bush roads. The Humlin property covers the central portion of the Red Lake Greenstone Belt, and is transected by a broad (>1 km wide), ‘Mine Trend’ parallel, regional-scale, northwest-trending structure referred to as the Pipestone Bay – St. Paul Bay deformation zone. The structure parallels structures observed in the Campbell and Red Lake mines area, and is considered important as a possible conduit for auriferous fluids. Numerous cross-faults have been interpreted from magnetic breaks, which may be important gold trap sites. The area is underlain by tholeiitic to komatiitic flows and ultramafic intrusions of the 2.98 to 2.96 Ga Balmer assemblage, and lesser felsic tuff and siliciclastic rocks of the 2.74 to 2.73 Ga Confederation assemblage, which overlies the Balmer assemblage on a regional unconformity. All of the major deposits in the belt are found within a few hundred metres of the unconformity, including the Madsen Mine (2.6 Moz) where mineralization is localized along the unconformity surface. The western margin of the Dome stock (2.72 Ga) underlies the southeast corner of the claim group, whereas the Killala-Baird batholith (2704 Ma) underlies the southwest corner. Minor gold occurrences (1-5 g/t Au) are found throughout the property, and several significant multi-ounce arsenopyrite-quartz vein gold prospects occur along trend on neighbouring patents to the south that are controlled by Goldcorp (e.g. Redruth and Humlin patents). The high-grade Alcourt prospect forms a small hole in the north central portion of the Humlin Property. Hydrothermal alteration includes locally intense Fe-carbonate and fuchsite (potassic) alteration of mafic and ultramafic rocks, disseminated tourmaline in quartz-rich sedimentary rocks overlying the angular unconformity, and talc alteration of ultramafic rocks. Alteration zones are locally associated with elevated to strongly anomalous arsenic.

Transfer 50,000 shares to Rubicon Minerals Corp. $250,000 work in first year (2006) $400,000 work in second year (2007) $600,000 work in third year (2008) $1,250,000 work in fourth year (2009) For a total of $2,500,000 Partnership As an added benefit of these agreements Rubicon Minerals Corp. has agreed to, when possible, review work programs and offer advice on our existing Red Lake properties based on upon their considerable knowledge in the area. Through its English Royalty Division, Rubicon Minerals Corp. holds the 2% underlying royalty for the Company’s Chukuni, South Baird, and Heyson property, so it is of interest to both companies that these projects are successful. Mr. Garry Clark, P.Geo, will be the Qualified Person on the Chukuni property. About Solitaire Minerals Corp.
