London and Toronto, 25 May 2012: Minera IRL Limited ("Minera IRL" or the "Company"), (TSX:IRL) (AIM:MIRL) (BVL:MIRL) the Latin America gold mining company, announces that it has filed a preliminary short form base shelf prospectus with the securities regulatory authorities in each of the Provinces of Canada, other than Quebec. These filings, when made final, will allow the Company to make offerings of debt securities, ordinary shares, warrants to purchase ordinary shares, warrants to purchase debt securities, and securities convertible into or exchangeable for ordinary shares (collectively, the "Securities") or any combination thereof up to an aggregate initial offering price of CAD$80,000,000 during the 25-month period that the final short form base shelf prospectus, including any amendments thereto, remains effective. Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in an accompanying shelf prospectus supplement and, subject to applicable regulations, may include 'at-the-market' transactions, private placements, public offerings or strategic investments. Unless otherwise specified in a shelf prospectus supplement, the net proceeds from the sale of the Securities will be used for general corporate purposes including capital expenditures and working capital.

Mr Courtney Chamberlain, Minera IRL's Executive Chairman, commented: "With the Company having completed an equity offering in March 2012 and with a cash balance of $30.3 million as at the end of March 2012, the Company has no immediate plans to issue securities covered by the shelf prospectus. Having a shelf prospectus in place however, increases the Company's flexibility to complete future financing transactions in a timely and efficient manner as required."

Santa Cruz 830, Piso 4, Miraflores, Lima 18, Peru, Telephone +51 1 418 1230, Attn: Corporate Secretary, or can be found on SEDAR at www.sedar.com.
