Dupax
The Dupax EPA comprises two separate blocks – Dupax (5,042 hectares) and Solano (3,814 hectares) – totaling some 8,856 hectares in area. The EPA is located in Nueva Vizcaya Province, some 200km north of Manila.
The Dupax block contains a previously identified and partially open pit mined zinc-copper-gold massive sulphide deposit. The deposit occurs as a massive sulphide body in agglomerate and disseminated sulphide in silicified sediments, predominantly underlain by marine clastics intercalated with pillow basalts and pyroclastics. This package is intruded by dikes and sills of intermediate to basic composition.
Major structures strike northwest and grossly conform to the trend of the mineralized zones. Principal ore minerals are sphalerite, chalcopyrite, tennantite and secondary covellite. The best grades obtained from sampling of the outcrop are 45.7% zinc, 3.89% copper and ~4g/t gold.
Previous work focused on defining a restricted lens of high-grade, direct shipping massive sulphide zinc-copper ore which was partially mined out by open pit methods (ca 1960/70s). Previous production records are currently unknown.
Gossans and manganese mineralisation occurs along strike of the main fault structure and show potential for additional massive sulphide deposits in the area. Geological logs of tunnels excavated during the 1960s(?) describe a weathered and oxidized profile of 12 meters thickness, which would make surface prospecting for massive sulphides more difficult. Gossanous material at surface is the best indicator of sulphide mineralisation at depth.
The Dupax block is a poorly explored area which hosts economic grades of massive sulphide Zinc-Copper-Gold mineralization. There appears to be an obvious structural control on the mineralization.Little is known about the Solano block. Once the EPA has been granted, the Company intends to carry out detailed geological mapping, soil geochemistry, followed by geophysical surveys to determine favourable areas for drill testing.
