three provinces that are most productive copper and gold producers in the philippines
Mines and Geosciences Bureau Region 13 (Philippines) In terms of potential for gold, Surigao del Norte still ranks high followed by Agusan del Sur and Agusan del Norte. For porphyry copper, rank is still the same although Agusan del Norte have a slight edge than Agusan del Sur as low-level diorite is already exposed in the Asiga area. At present, Surigao del Sur relatively ranks as lowest in potential for both epithermal gold and porphyry copper prospects among the provinces of the Region although its prospectivity may improve as exploration work progresses in the future.
Andes There is a long history of mining in the Andes, from the Spanish silver mines in Potosí in the 16th century to the vast current porphyry copper deposits of Chuquicamata and Escondida in Chile and Toquepala in Peru. Other metals including iron, gold and tin in addition to non-metallic resources are important.
