Mirasol Commences Phase Two Drilling at the Virginia Project, Argentina

February 15, 2011

VANCOUVER, BC, February 15, 2011 – Mirasol Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R) is pleased announce that Phase 2 diamond drilling has commenced on its 100%-held Virginia property, located in Santa Cruz Province, Argentina. Phase 2 drilling is designed to further explore the Julia Vein and possibly other targets identified through surface exploration.

The Phase 1 program of 28 diamond drill holes tested segments of the 2,200-metre long Julia vein and was reported by Mirasol on December 16, 2010 and January 13, 2011. The first campaign was designed to intersect the Julia structure at approximately 25 and 50 metres below surface, and returned significant silver-mineralized widths of iron-rich, oxidized vein material and adjacent volcanic wall rock. These include intersections of between 9 and 26.6 metres with grades between 250 and 1,000 grams per tonne (g/t) silver, which include higher grade internal intervals with assays of between 1,000 g/t and 6,298 g/t silver.

“We are very pleased with the silver results from Phase 1 drilling at the Virginia vein system, which confirmed grades from surface channel chip sampling. The next phase of exploration drilling is designed to provide additional information on the Julia Vein and to step out along strike and to depth. In addition, Phase 2 may test other targets outside the Julia Vein,” stated Mary Little, president of Mirasol Resources.

Mirasol Resources Ltd. is a prospect generation exploration company focused on the discovery and acquisition of new, high-potential precious metals deposits in the Americas. Mirasol currently holds 100% of the rights of twenty exploration prospects, including eight advanced exploration properties located in Santa Cruz Province in the Patagonia region of southern Argentina. The Joaquin Project is under joint venture with Coeur d’Alene Mines. The company operates subsidiary companies in Argentina and Chile, holds the strategic Rubi copper-gold porphyry property in Chile, and is engaged in generative exploration in prospective regions elsewhere in the Americas.
