Reference information

Comments Mapawa exploration target: diorite-hosted copper-gold porphyry system with intact cap in altered andesite; drill intercepts 53 m of 0.2% Cu, 0.8 g/t Au, and 2.4 g/t Ag. Mabuhay: old gold mine (underground 1957 to 1953; open pit 1995–2000); exploration target for a deep porphyry copper-gold system associated with high-sulfidation epithermal gold deposit; drill intercept (1 hole) 243 m of 0227% Cu, 0.24 g/t Au, and 0.0088% Mo. Drilling to 770 and 1,000 m in other holes encountered only weakly altered diorite, possible diatreme breccia.
