About Berta

Berta is a modest sized, near surface, copper oxide deposit, with mineralization, as defined by drilling, mapping and geochemistry, occurring in three principal areas; Berta Sur, Central and Norte. Mineralization is associated with sub-vertical, elongate, potassically altered porphyry intrusive bodies and related hydrothermal and intrusive breccias, emplaced into a tonalite stock. At Berta Sur, this mineralization is present within a roughly horseshoe shape area with oxidation extending from surface to depths of 50m to 100m. Berta Central comprises several smaller bodies, located immediately north of Berta Sur, which were the focus for previous small scale copper oxide production. Berta Norte comprises several, discreet, NW oriented zones of mineralization, individually 25-85m in width, 100-250m in strike length and partially gravel covered.

Marimaca Copperannounced a NI43-101 compliant resource estimate for the Berta Sur area, in its news release dated December 6th 2012, the results of preliminary metallurgical test work in its news release dated November 5th 2012, and the signing of a Letter of Intent with ProPipe in its news release dated May 8th 2013. There are additional resources on the property in the Berta Central deposits, and there is potential elsewhere on the property and in the surrounding district to augment these.
