Summary table:

Commenting on the Q3 results, Courtney Chamberlain, Minera IRL Limited Executive Chairman, said: "The third quarter to 30 September 2011 was another strong performance by Minera IRL from both a financial and operational perspective. The better than expected financial results were again driven by above budget gold production at our Corihuarmi Gold Mine and the increasing gold price. The Company also recently achieved an important milestone with the completion of a very satisfactory Pre-Feasibility Study at Ollachea Project in Peru during the quarter. At the Don Nicolas Project in Argentina, an upgraded resource statement was released, which will be the basis of the Feasibility Study targeted for completion by late 2011. The release of a 0.9 million oz maiden Inferred Resource for the Concurayoc Zone further highlighted the exploration potential at the Ollachea Project."
