Philippine Mining Service Corporation (PMSC) was established on June 16, 1980 as a subsidiary of Kawatetsu Mining Co. Ltd. and Kawasaki Steel Corporation, both of Tokyo, Japan, to fulfill the vision of developing the huge dolomite deposit located at the municipalities of Alcoy and Dalaguete, province of Cebu, Philippines. The Company operates by virtue of a service contract between the mining lease contract holders Dolomite Mining Corporation (DMC).

PMSC pioneered in the production of quality dolomite the entire Philippines and became the major supplier of raw dolomite to leading steel and glass companies in Japan as well as to the largest sintering Plant in Southeast Asia (Mindanao Island, Philippines). Likewise, the company now serves the growing demand for dolomite in the Philippine agriculture and construction industry.

After over 20 years of successful operation, the company has produced and sold about 15 million metric tons of quality dolomite in the export and domestic markets.

On April 1, 2001, the company acquired the limestone mine in Garcia, Hernandez, Bohol, Philippines, which was formerly managed by its sister company - Philippine Sinter Corporation. At present, PMSC has increased its capital and production of quality dolomite and limestone to ensure a continuous supply of the product to the different end users in Japan and other Asian Countries.

The company trains its sight to even higher production to meet the increasing demand for dolomite and limestone with the support and cooperation of its dedicated Filipino staff and workers.
