Soltoro Outlines Significant Near Surface Silver Mineralization at Catarina Mine Area in Jalisco, Mexico

TORONTO, ONTARIO--(Marketwire - July 27, 2010) - Soltoro Ltd. (TSX VENTURE:SOL) has compiled results of a comprehensive programme of channel sampling in surface trenches over the previously producing Catarina Mine zone on its El Rayo property in Jalisco Mexico. The Catarina mine hosts the most significant historic resource at El Rayo. A preliminary diamond drill program returned 115 gpt silver over 46.5 metres including 269 gpt silver over 12 metres. Trenching was carried out to outline the dimensions of the mineralized zone in preparation for future drilling. The trenching has outlined a zone which is 500 metres long and 10 to 35 metres wide, within which all of the samples returned values over 25 g/t silver, with numerous continuous channel samples over 100 g/t silver. The highest individual average grade was 244 g/t silver over a total of 6.2 metres while the widest single trench was 78 g/t Ag over a total of 36.4 metres, within which a core section averaged 154 g/t silver over a length of 11.9 metres. Other significant continuous sections include 141 g/t silver over 21.5 metres, 123 g/t silver over 13.7 metres, 172 g/t silver over 11.5 metres and 153 g/t silver over 5.7 metres.

The average results for each trench are shown on the plan and longitudinal section posted on the company's website at www.soltoro.com/CatTreJul10.pdf. This shows the overall extent of the trenching program relative to the historical surface and underground workings, illustrating that the mineralization is far more continuous over far longer strike lengths and greater widths than were mined historically, at which time average production cut-off grades were far higher.

Together with the previously completed six diamond drill holes beneath these old workings, the current sampling has shown that the mineralization extends over a vertical extent of at least 250 metres, and is open at depth and along strike at both ends. The company's geologists are currently reviewing the remainder of the analytical results for both gold and base metals, which historically were produced at the Catarina Mine.

Andrew Thomson, President and Chief Executive Officer, stated: "The El Rayo structure silver zone potential at Catarina remains undefined and this programme has served to confirm the zone hosts considerable near surface potential. The zone outlined is comparable in length and depth to the Las Bolas zone where the Company has outlined a significant indicated and inferred silver resource."

The company is currently completing further percussion and diamond drilling on the Las Bolas deposit to test the depth extent of the wide zones of mineralization detected in the deepest holes completed previously. Results of this deeper drilling will be released as the assays become available. An NI 43-101 report at Las Bolas returned the following resources:

Diamond drilling continues in the Las Bolas resource area to test the extent and continuity of the mineralization to the north and at depth. The samples from this drilling will also be used for further metallurgical testing. The Company has requested quotes for further metallurgical testing with the objective of achieving a higher recovery rate in order to be able to reduce the cut-off grade thereby increase the size of the current resource. The resource was based on a conservative 65% recovery, whereas bottle roll testing at minus 100 mesh returned up to a 78.6% silver recovery after 120 hours. Once results of the current drilling at Las Bolas have been compiled, a decision will then be made as to when to drill at the Catarina mine along the El Rayo structure.

Assaying from this program was completed by ALS Chemex through their office in Guadalajara, Mexico. Gold was analyzed using a 30g fire assay with AA finish while the silver is analyzed using a four acid "near total" digestion package. Mr Terence J. Bottrill, P.Eng., a consultant, member of the advisory board of the Company and a qualified person as defined by NI 43- 101 has reviewed and approved the contents of this press release. Field supervision of the El Rayo project is provided by Mr. Chris Lloyd, M.Sc., Vice President, Exploration.
