Minera IRL Limited ("Minera IRL" or the "Company"), (TSX:IRL)(AIM:MIRL)(BVLAC:MIRL) the Latin America gold mining company, is pleased to report that it has closed the previously announced best efforts offering of ordinary shares ("Shares") of the Company (the "Offering") at a price of C$1.13 per Share (72p per ordinary share, converted at the Bank of Canada daily noon rate on 23 February, 2012 and rounded to the nearest penny). The Company filed a final short form prospectus ("Final Prospectus") with the securities regulatory authorities in each of the provinces of Canada, except Québec, in connection with the Offering on 28 February 2012. Concurrent with the closing of the Offering, the Agents exercised in full their over-allotment option of 2,660,000 Shares. Including the Shares issued as a result of the exercise of the over-allotment, a total of 29,260,000 Shares were issued, raising gross proceeds of C$33.1 million.

"The closing of this Offering, which was well supported by existing and new shareholders, allows Minera IRL to consolidate and build upon the progress we have made toward becoming a mid-tier gold producer by 2015", said Courtney Chamberlain, Executive Chairman. "In 2011 we added significant new gold resources, completed a successful pre-feasibility study on our flagship Ollachea Gold Project and, most recently, completed a successful feasibility study on our Don Nicolas Project in Patagonia, Argentina. During 2012 we expect to complete the full feasibility study at Ollachea, permit and commit Don Nicolas to development and continue with our exploration programs in Peru and Argentina."

The Company intends to use the net proceeds of the Offering, together with its existing cash resources to complete the exploration and development tunnel, feasibility study and further exploration programmes at Ollachea, to undertake brownfield exploration, permitting and detail engineering at Don Nicolas and conduct exploration programmes in the wider Patagonia region with the remainder for working capital and general corporate purposes.

The Offering was completed by a syndicate of investment dealers led by RBC Capital Markets as sole global bookrunner and Jennings Capital Inc. and Haywood Securities Inc. with Collins Stewart Europe Limited and FinnCap Limited as special selling agents in the United Kingdom only (collectively, the "Agents").
