    Minera IRL Update on Pan de Azucar Gold Exploration Project, Santa Cruz, 
                                    Patagonia 
 
 
London, 20 September 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, is pleased to announce an update on the Pan 
de Azucar Gold Project in Patagonia, Argentina. 
"Pan de Azucar represents a high quality gold exploration project." stated 
Courtney Chamberlain Minera IRL Limited Executive Chairman.  "This recently 
mapped fertile quartz vein structure with bonanza surface gold assays, up to 54 
g/t from rock chip sampling, is supported by new high-resolution heliborne 
magnetic-radiometric data. We now have a compelling target for the first round 
of drilling which is scheduled to commence in mid-October." 
Pan de Azucar represents a low-sulphidation epithermal vein system that outcrops 
over a strike length of approximately 1.3 kilometers.  Surface rock chip 
sampling has returned numerous elevated gold values of up to 54g/t.  The main 
quartz-lode structure, up to 3 meters wide, is surrounded by a gold-silver 
anomalous stockwork halo up to 35 meters thick. 
 
Results from a recent heliborne geophysical survey clearly define a strong 
northeast trending magnetic low anomaly associated with the outcropping vein 
structure.  This signature is consistent with other well-known epithermal vein 
systems in the region. 
 
Pan de Azucar is one of three known epithermal vein exploration projects, with a 
total outcrop exceeding 9 kilometers in length, located within Minera IRL's 
larger Chispas package of leases in Santa Cruz Province, Argentina.  The 
projects are situated within the geologically important Deseado Massif, an 
emerging world-class epithermal vein province which hosts the Cerro Vanguardia, 
Cerro Negro and Cerro Moro epithermal vein fields. 
 
Minera IRL Patagonia holds exploration licenses over some 2,700 square 
kilometers of prospective ground in the Deseado Massif which includes the 
Company's Don Nicolas Project, currently undergoing a feasibility study, and the 
recently announced Escondido discovery. 
 
Additional information, including plans, surface assays and the magnetic 
geophysical map, is available from the Company's web site, www.minera-irl.com.
