Commenting on the Q3 results, Courtney Chamberlain, Executive Chairman of Minera IRL said:

"The Corihuarmi Gold Mine in Peru continues to perform above our expectations and underpins the financial strength of the Company as we continue to invest in the development of our substantial pipeline of projects. It is a great credit to the operating efficiency of our production team to treat ore with a grade below 0.5g/t at a site cash operating cost well under $600 per ounce."

"On the development front we have almost completed the Definitive Feasibility Study on Ollachea, the Company's flagship project in southern Peru and are on schedule to announce the results during fourth quarter of 2012. Also at Ollachea, the exploration drive is progressing exceptionally well and has surpassed the half-way point reaching 669 meters by 31 October. Drilling from underground to explore the eastern strike of the deposit is scheduled to commence shortly."

"In Patagonia, Argentina, the Company has received approval of its Environmental Impact Assessment and been granted a Development Permit in less than 5 months. This is unprecedented turn-around of this process and management is very pleased with the support and assistance provided by the Santa Cruz government. We are now in a position to take the final steps towards the development of Don Nicolas."
