Minera IRL Limited ("Minera" or the "Company"), (TSX:IRL)(AIM:MIRL)(BVLAC:MIRL) the Latin America gold mining company, announces that it has filed a Prospectus Supplement to the Base Shelf Prospectus dated July 12, 2012 with the securities regulatory authorities in each of the Provinces of Canada, other than Quebec, in relation to a marketed offering (the "Offering") of 21,550,000 ordinary shares ("Shares") in the capital of the Company at a price of C$0.71 per share (£0.45 per ordinary share, converted at the Bank of Canada daily noon rate on 31 January 2013 and rounded to the nearest penny) for gross proceeds of up to C$15,300,500. The Offering is expected to close on or around February 7, 2013.

The Offering has been conducted on a marketed basis through a syndicate of investment dealers led by RBC Capital Markets as sole global bookrunner and including Jennings Capital Inc., Fraser Mackenzie Limited and Desjardins Securities Inc. (collectively, the "Agents"). The Agents have engaged Canaccord Genuity Limited and finnCap Limited to act as special selling agents solely in connection with the Offering in the United Kingdom and KALLPA Securities Sociedad Agente de Bolsa S.A. to act as special selling agent solely in connection with the Offering in South America and the Caribbean.

The Company has also granted the Agents an over-allotment option to purchase up to that number of additional Shares equal to 15% of the number of Shares sold pursuant to the Offering. The option will be exercisable for a period of 30 days following closing.

The net proceeds from the Offering will largely be directed toward funding early development costs of the Ollachea Project in Peru which, following a successful definitive feasibility study announced in late 2012, is currently in the permitting stage. The Company intends to use the proceeds as set out in the table below.
