Minera IRL Update on Pan de Azucar Gold Exploration Project, Santa Cruz, Patagonia

LONDON, UNITED KINGDOM--(Marketwire - Sept. 20, 2010) - Minera IRL Limited ("Minera IRL" or the "Company"), (TSX:IRL)(AIM:MIRL)(BVLAC:MIRL) the Latin American focused gold mining, development and exploration company, is pleased to announce an update on the Pan de Azucar Gold Project in Patagonia, Argentina.

"Pan de Azucar represents a high quality gold exploration project." stated Courtney Chamberlain Minera IRL Limited Executive Chairman. "This recently mapped fertile quartz vein structure with bonanza surface gold assays, up to 54 g/t from rock chip sampling, is supported by new high-resolution heliborne magnetic-radiometric data. We now have a compelling target for the first round of drilling which is scheduled to commence in mid-October."

Pan de Azucar represents a low-sulphidation epithermal vein system that outcrops over a strike length of approximately 1.3 kilometers. Surface rock chip sampling has returned numerous elevated gold values of up to 54g/t. The main quartz-lode structure, up to 3 meters wide, is surrounded by a gold-silver anomalous stockwork halo up to 35 meters thick.

Results from a recent heliborne geophysical survey clearly define a strong northeast trending magnetic low anomaly associated with the outcropping vein structure. This signature is consistent with other well-known epithermal vein systems in the region.

Pan de Azucar is one of three known epithermal vein exploration projects, with a total outcrop exceeding 9 kilometers in length, located within Minera IRL's larger Chispas package of leases in Santa Cruz Province, Argentina. The projects are situated within the geologically important Deseado Massif, an emerging world-class epithermal vein province which hosts the Cerro Vanguardia, Cerro Negro and Cerro Moro epithermal vein fields.

Minera IRL Patagonia holds exploration licenses over some 2,700 square kilometers of prospective ground in the Deseado Massif which includes the Company's Don Nicolas Project, currently undergoing a feasibility study, and the recently announced Escondido discovery.

Additional information, including plans, surface assays and the magnetic geophysical map, is available from the Company's web site, www.minera-irl.com.

Minera IRL Limited is the AIM traded and TSX and BVL listed holding company of precious metals mining and exploration companies focused in Latin America. Minera IRL is led by an experienced senior management team with extensive industry experience, particularly in operating in South America. The Group operates the Corihuarmi Gold Mine and the emerging Ollachea Gold Project in Peru as well as the Don Nicolas Project in Argentina.
