LONDON, UNITED KINGDOM--(Marketwire - May 12, 2010) - Minera IRL Limited ("Minera IRL" or the "Company"), (TSX:IRL)(AIM:MIRL)(BVLAC:MIRL) the Latin American focused gold mining, development and exploration company, announces drilling results at the new Concurayoc Zone, Ollachea Project, Southern Peru.

Highlights:

• Five drill intersections over a 500 meter strike length at Concurayoc including intersections of 20.9m of 3.07g/t Au, 14m of 2.91g/t Au and 8m of 5.08g/t Au
• Concurayoc is 300 meters along strike from the Minapampa Zone where a pre-feasibility study is in progress
  
• The results warrant a major follow-up drilling program in this zone

"The new Concurayoc zone is relatively close to the Minapampa Zone, where we have identified an inferred resource of 1.3 million ounces of gold (8.9 million tonnes at 4.5 grams gold per tonne) and are currently undertaking a pre-feasibility study. This new zone is expected to allow development synergies if we successfully define a significant additional resource said Courtney Chamberlain, Executive Chairman of Minera IRL. "The latest drilling further demonstrates the increasing potential for the mineralized sedimentary rocks which we have thus far shown to extend for almost 2 kilometers, which still remain open along strike in both directions as well as down dip."

In the Concurayoc Zone, located some 300 meters west of Minapampa, surface geological and structural mapping results, together with exploration drill-hole data, has demonstrated that the strike of the mineralized slate beds is flexed approximately 25ºtowards the southwest. Mineralized intersections have been obtained in five exploration holes over a strike length of approximately 500 meters. DDH09-74 intersected 20.9m averaging 3.07g/t Au (including 8m at 5.18g/t Au), and DDH10-81 intersected 14m grading 2.91g/t Au (including 6m grading 3.59g/t Au). These more recently drilled holes are interpreted to be part of the same gold-bearing lenses intersected in drill-hole DDH08-15, drilled in late 2008, which included 8m at 5.08g/t Au.

While two drill rigs are presently committed to the Minapampa pre-feasibility drill out, further follow-up drilling at Concurayoc will represent a high priority as additional rigs become available.

It should be noted that the effective true width of mineralized intersections as reported are expected to range between 90% to 97% of the width indicated, depending on the variation of the angle of incidence between the Concurayoc exploration drill-hole(s) and the drilled mineralized horizons.

Drill intersections from DDH08-01 through to DDH10-96, as well as a summary of the relevant Quality Assurance and Quality Control Procedures Disclosure can be found on the Minera IRL website at [ www.minera-irl.com ].
