Soltoro Increases Equity Ownership in Argentum Silver Corp. to 14%

Soltoro Ltd. (TSX VENTURE:SOL) has received an option payment from Argentum
Silver Corp. (TSX VENTURE:ASL) whereby an additional 3,500,000 common shares and
a payment of CDN $120,000 were made to Soltoro towards the acquisition of
Soltoro's Victoria and Coyote silver gold properties in Jalisco State, Mexico.
Soltoro now holds a total of 6,300,000 shares of Argentum Silver (14% of the
outstanding shares of Argentum Silver). Under the terms of the option agreement
signed on April 25, 2011, Argentum Silver must evidence certain exploration
expenditures in order to complete a 100% transfer of title interest of the
Victoria and Coyote properties to Argentum Silver. On transfer of the
properties, Soltoro will retain a 3% Net Smelter Return interest in each project
whereby 1% can be purchased by Argentum Silver for US$1.5 million to a maximum
of 2% for each project. Soltoro also retains the right to participate in
additional Argentum Silver financings to maintain its percentage equity
interest.


Andrew Thomson, President and C.E.O. of Soltoro, stated: "Soltoro has
successfully monetized the Victoria and Coyote properties whereby the Company
participates on a royalty basis on the Coyote and Victoria properties while also
participating on an equity basis on all of Argentum Silver's properties. Soltoro
remains focused on expanding silver resources at its El Rayo Primary Silver
Project."


At Coyote, Argentum Silver recently announced completion of the first phase, 25
diamond drill hole program. A total of 2,686 metres were drilled on the four
identified vein zones: 11 holes on the El Tajo zone, seven holes on the La
Florida zone, four holes on the Bocancha zone and three holes on the La Colorada
zone. Argentum's original drill program called for 19 holes to be drilled;
however, the high grades intercepted in hole 2012-3, which included 2.0 metres
of 2,745 grams per tonne silver, and in hole 2012-7, which included 1.2 metres
of 1,645 grams per tonne silver, encouraged Argentum to increase the number of
holes drilled to 25. Results from the first seven holes were announced by news
releases dated Feb. 29 and March 6, 2012. Argentum Silver has yet to release the
remaining 18 holes.


Prior to the April 25, 2012 share issuance, Soltoro owned 2,800,000 common
shares of Argentum Silver representing approximately 6% of their current
outstanding shares. As a result of the share issuance Soltoro now owns 6,300,000
shares of Argentum Silver, representing 14% of their outstanding shares. The
3,500,000 shares of Argentum Silver are being issued to Soltoro from treasury
pursuant to the option agreement entered into April 25, 2011 at a deemed price
by Argentum Silver of $0.30 per share. The closing price of Argentum Silver's
shares on the TSX Venture Exchange on April 25, 2012 was $0.18 per share.

including its financial performance, and depending upon these factors, market
conditions and other factors, Soltoro may increase or decrease its beneficial
ownership in Argentum Silver as it deems appropriate. The Share Issuance was
