Minera IRL Limited - Corihuarmi Gold Mine Production June Quarter, 2010

London, 14 July 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, announces production results from its Corihuarmi Gold Mine for the quarter ending June 2010.

Highlights:

·; Gold production of 8,098 ounces, 10% above budget

·; Quarterly cash operating costs of $365 per ounce

·; Gold sales prices for the quarter averaged $1,201 per ounce

·; Permitting to increase treatment rate by 35% in 2011

Corihuarmi production results are summarized in the table below:

Minera IRL Limited Executive Chairman, Courtney Chamberlain, comments "Corihuarmi has, once again, performed beyond our expectations. Gold production was 10% above budget and spot gold sales achieved a price of over US$1,200 per ounce. The net effect was that revenue from Corihuami for the quarter of US$9.9 million exceeded the previous quarter by US$1.5 million and the corresponding quarter of 2009 by US$3.2 million, close to a 50% increase. The margin also improved with costs decreasing to US$365/oz providing increased cash to apply to our project development and exploration activities."

An amended Environmental Impact Assessment will be lodged in the next quarter with the authorities to allow ore production to be increased by 35% to 2 million tonnes per annum in 2011. This will allow economies of scale to be applied toward profitably treating lower grade ore which will be particularly attractive at high gold prices. The extra capacity will also allow large scale production trials on broken scree material with an inferred resource of 3,765,000 tonnes grading 0.45g/t containing 54,600 ounces of gold.
