The geophysical results posted on the website, www.minera-irl.com, relate to four sizeable project areas, Escondido, Pan de Azucar, La Paloma and Martinetas.

This is part of a major 4,482.6 line kilometer heliborne, high resolution magnetic survey which was flown mid-2010.

The processed results highlight the promising geological prospectivity of the areas and have identified a number of new targets and extensions to existing targets.

New targets depict similar magnetic signatures to known mineralization and other prospective structures in the areas mentioned.

Follow up exploration programs, including geological mapping, surface geochemical sampling and first-phase exploration drilling are planned to test the results of the geophysically anomalous areas.
