Rosalito Copper Project, Argentina
The Rosalito project in Santa Cruz province, Argentina is a 10,000-hectare exploration claim staked by Pacific Rim during fiscal 2005 to cover a potential supergene enrichment blanket related to a porphyry copper system. Rosalito comprises iron oxide-stained, bleached rhyolite tuffs and volcaniclastics that surround a leached sulfide breccia. This porphyry copper-style alteration system occurs along the edge of a range front with adjacent alluvial-covered areas. A 0.5-meter wide sulfide vein that crosscuts the breccia returned 9.57% zinc, 2.1% copper and 47 g/t silver. Porphyry copper systems are known to occur in the same geological environments as the epithermal gold systems Pacific Rim is seeking, and it is not uncommon to find one in the search for the other. As Pacific Rim is focused on epithermal gold systems, the Company plans to option or joint venture the Rosalito project to a suitable partner.
