Commenting on the Q2 results, Courtney Chamberlain, Executive Chairman of Minera IRL:

"The Corihuarmi Gold Mine in Peru continues to perform above our expectations and underpins the financial strength of the Company for the short term as we continue to invest in the development of our substantial pipeline of projects."

"As previously stated, the grade at Corihuarmi will continue to decline as the mine matures. Despite this, the mine continues to perform well and is generating strong cash flows due to a focus on controlling site operating costs and maximizing throughput. To date the Corihuarmi mine has produced approximately 164,000 ounces, which is 48% more gold than the 111,000 ounces estimated in the original feasibility study. Furthermore, the Company has already extended the anticipated mine life by more than three years to 2015 and we believe we have opportunities to extend the life of mine even further."

"On the development front, good progress was made on the feasibility study, due for completion in the fourth quarter 2012, at the Company's flagship project, Ollachea, in southern Peru. Also at Ollachea, progress on the exploration drive has reached more than 200 meters and drilling from underground to explore the eastern strike of the deposit is scheduled to commence later in the year. In Patagonia, Argentina, permitting on the Don Nicolas Project was commenced with the submission of the Environmental Impact Assessment."

"I am pleased with the progress Minera IRL has made in its stated strategy of bringing the Ollachea and Don Nicolas gold projects into production over the next 2 to 3 years and becoming a mid tier gold producer."
