Minera IRL Declines to Exercise La Falda and Killincho Options

London, 24 September 2010: Minera IRL Limited ("Minera IRL" or the "Company"), (TSX:IRL) (AIM:MIRL) (BVL:MIRL) the Latin American focused gold mining, development and exploration company, advises that the pending options to acquire the La Falda Project in Chile and the Killincho Project in Peru will not be exercised.

Evaluation of the gold and copper assay results of a 5,174 meter diamond drilling program into the La Falda porphyry chargeability anomaly has downgraded the potential for an economic, near surface discovery. As a result, the Company has advised joint venture partner, Catalina Resources Ltd, that the option to perfect a 75% equity position will not be exercised when it expires on 30 September 2010.

Minera IRL has also advised Ingenieria y Tecnologia Minero-Metalurgica SA ("ITMM") that it will not proceed with the option to acquire several properties that constitute the Killincho Project in southern Peru. While an extensive exploration program in recent months has confirmed the presence of significant gold, the Company has elected not to proceed due largely to logistic and infrastructure challenges.

Courtney Chamberlain, Minera IRL Limited Executive Chairman, stated "Our team did a fine job of exploring La Falda and Killincho but we take a pragmatic approach to this high risk end of the business. The Company continues with a substantial exploration program on a number of high quality gold targets in two areas of Peru and the Deseado Massif in Argentina, where we recently announced a new discovery at Escondido".
