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.
Mines and Geosciences Bureau Region 13 (Philippines) Geologically, manganese prospects in the region are typically associated with basaltic rocks. Numerous, although sporadic occurrences are reported in the basalts in Surigao del Sur as well as in basalt â€“ limestone contact in RTR town, Agusan del Norte. Continuity is less established and is deemed amenable at present to small scale mining.
