Cagdianao Mining Corporation

The Cagdianao mine site is located in the municipality of Cagdianao, at the Northeastern side of the province of Dinagat Islands. Its area of operations is within the Surigao Mineral Reservation. CMC exports saprolite and limonite ore.

Cagdianao has 14 barangays within its 249.48 square kilometer territory, including CMC’s host and neighbours – Valencia, Boa, Legaspi and Bayanihan. The island where it is located is a declared Mineral Reservation site since 1939 due to its abundant mineral resource. Moreover, it is a Key Biodiversity Area due to its flora and fauna, especially in the areas of Mt. Redondo and Mt. Cambiliw. The Maraguing Watershed, one of the main sources of the mine site’s domestic water supply and the Valencia Marine Protected Area are among the areas adopted by the CMC for protection.
