where can manganese be found in the philippines
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.
