Minera IRL Announces Positive Drilling Results from Concurayoc Zone, Update Ollachea Project, in Southern Peru

LONDON, UNITED KINGDOM -- (Marketwire - Nov. 29, 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 a drilling results update for the new Concurayoc Zone, Ollachea Project, Southern Peru.


Highlights:

* All six new drill holes at Concurayoc have intersected potentially economic zones of gold mineralization

* Drill hole DDH10-130 intersected 33 meters grading 4.57g/t gold including 12 meters grading 8.66g/t gold. Hole DDH10-127 intersected five zones, 3 meters grading 4.55g/t, 4 meters grading 7.05g/t, 4 meters grading 2.16g/t, 8 meters grading 3.78g/t and 11 meters grading 3.56g/t gold

* Extended strike length of 550 meters remains open along strike and down dip

* Drilling is continuing and an inferred resource estimate is scheduled for completion for towards the end of the first quarter 2011


A new discovery at the Ollachea Project was announced in May at Concurayoc, located some 300 meters west of the million plus ounce Minapampa Zone where Minera IRL will complete a pre-feasibility study in the second quarter of 2011. Exploration diamond drilling has recommenced at Concurayoc and assay results have been received from six new holes. Results include DDH10-127 which intersected five zones, 3 meters grading 4.55g/t, 4 meters grading 7.05g/t, 4 meters grading 2.16g/t, 8 meters grading 3.78g/t and 11 meters grading 3.56g/t gold and hole DDH10-130 which intersected 33 meters grading 4.57g/t gold including 12 meters grading 8.66g/t gold.

"The new Concurayoc zone is shaping up very well with most recent intersections significantly better than the discovery results announced in May" said Courtney Chamberlain, Executive Chairman of Minera IRL. "This new zone is close enough to Minapampa to allow significant future development synergies. Further exploration potential is very promising with the Minapampa/Concurayoc system remaining open along strike in both directions as well as down dip."

Concurayoc has now been tested by eleven exploration diamond drill holes along a strike of approximately 550 meters. It is anticipated that sufficient drill information will be available to estimate an inferred resource toward the end of the first quarter 2011.

It should be noted that the effective true width of mineralized intersections are expected to range between 71% to 98% of the width reported, with the majority of the drillholes reporting around 91% true width. The true width is dependant upon the variation of the angle of incidence between the trace of the Concurayoc exploration drill-hole(s) and the orientation of the drilled mineralized horizons.

Quality Assurance and Quality Control Procedures Disclosure

The Company has implemented and maintains a Minera IRL quality assurance/quality control (QA/QC) protocol on the Ollachea Project to ensure best industry practice in sampling and analysis of exploration and resource drill core samples. The insertion of field duplicates, certified standards and blank samples into the sample stream form part of the MIRL procedure (these act as an independent check on contamination, precision and accuracy in the analytical laboratory).

Assay results are reported once rigorous QAQC procedures have been approved.


Independent Audit Programs

Towards maintaining compliancy with international standards as they pertain to the minerals industry resource evaluation and estimation procedure, MIRL regularly contracts the services of industry experts to conduct detailed audits of established QAQC procedures.
