Minera IRL Board Approves Ollachea Exploration Drive

LONDON, UNITED KINGDOM and TORONTO, ONTARIO--(Marketwire - Aug. 31, 2011) - Minera IRL Limited ("Minera IRL" or the "Company"), IRLMIRLMIRL the Latin American gold mining company, announces the approval by the Board of Directors for a 1.2 kilometer long exploration drive at its flagship Ollachea Gold Project in Peru.

Highlights

--  The Board has approved a 1.2 kilometer exploration tunnel which will
    access the ore body defined in the Ollachea Pre-feasibility study
    announced in July 2011 
--  The drive will allow exploration drilling from underground along
    approximately one kilometer of eastern strike extension of the known
    mineralization which cannot be drilled effectively from surface 
--  A contract has been signed with well known Peruvian underground
    contractor JJC Contratistas Generales S.A. (JJC) to implement the
    project 
--  Permitting of the exploration drive is in place for an immediate
    commencement of the project

"Completion of the extremely positive Pre-feasibility Study at Ollachea provides the justification to commence the exploration drive into the ore body." said Courtney Chamberlain, Executive Chairman of Minera IRL. "This will allow drill testing from underground drill cuddies as the drive advances parallel to approximately one kilometer of eastward projected gold mineralization which, due to very steep terrain, is impractical to drill from surface. Detailed mining design information will also be gained that will be used in the Bankable Feasibility Study which is now commencing. This tunnel will also assist management's production schedule objective of late 2014."

The slightly inclined exploration drive will be from a portal site located in a deeper valley across the ridge from the outcropping mineralization at the Minapampa Zone. The Minapampa orebody will be accessed approximately 350 meters down-dip from the surface outcrop.

Drill exploration targets from underground are compelling. The gold bearing structures outcrop for approximately one kilometer to the east of the Minapampa Zones where 1.4 million ounces of gold (10.7 million tonnes at 4.0g/t Au) in the Indicated Resource category has been drill defined from surface. The most easterly drilling from surface recorded strong gold intersections and supports geological continuity of the open-ended Minapampa mineralization towards the east. Extremely steep terrain precludes further drilling from surface towards the east. The tunnel track has been designed parallel to this eastern strike extension to provide suitable locations for underground diamond drilling from cuddies, or chambers, at regular intervals as the drive advances.

Following a comprehensive tendering process, a contract has been signed with well known and experienced underground contractor, JJC, to execute the underground project. Consultants TWP Sudamerica S. A. have been engaged to assist Minera IRL to manage the project.

A general assembly of the Ollachea community has also overwhelmingly endorsed the project. The exploration drive has already been permitted by the Peruvian authorities and site access and portal establishment will be commenced shortly. The drive is scheduled to be completed over a 15 month time frame with a budget of US$14.9 million which includes a contingency of 10%.
