The mining property has 200 hectares located in Vitor district of Arequipa province, southern Peru. The geological regional frame is the Coastal Batholith (Batolito de la Costa) with a SE-NW orientation. Rosario Vein is the main mineralized structure in current prospecting, which strikes N50°W and dips 50°NE and outcrops in 250m length approximately. It has been recognized on 120m length with narrow underground sublevels and chimneys dipping down until 30m, which were surveyed, mapped and sampled. Gold mineralization is distributed in the milky and gray quartz accompanied by goethite and hematite that fill micro fractures. Intrusive host rock is tonalite with moderate argillic alteration in contact with the vein. The mineralized area corresponds to the oxidation zone, whose continuity is apparently evident both in depth and horizontal extent. No relicts of primary sulfides have been observed. Some representative values of vein width and grade are: 0.90 m with 4.30 Au gpt, 1.30 m with 5.33 Au gpt, 0.70 m with 6.17 Au gpt, 0.90 m with 8.27 Au gpt, 1.00 m with 13.87 Au gpt, 0.60 m with 15.13 Au gpt, 1.30 m with 7.50 Au gpt, 0.60 m with 11.88 Au gpt, 1.00 m with 12.44 Au gpt, 0.55 m with 17.80 Au gpt. Summary statistics with all available data until now give averages of 0.81 m width and 8.75 Au gpt weighted. Samples were assayed at J. Ramon Del Peru and Inspectorate Services Peru, two well known accredited Laboratories in Lima. With the ore extracted during the initial exploration, cyanide leaching tests have been made at pilot stage, obtaining good recovery results. In the same mining claim other economic mineralized structures has been prospected by means of artisan works. Those structures have a sub parallel strike and dip angle to Rosario Vein, in both hanging and footwall sides. Other gold vein structures exist toward the southeast in neighbor properties with active mining operations. All evidences suggest longitudinal extents reaching as far as 1 Km.
