In 1949, the vast mineral deposits of limestone used in portland cement production were noticed in Barrio Dumarang (now Quirino) by a mining engineer who was then a municipal councilor at that time. Because of the desire to create economic activity, the municipal council, through the efforts of this mining engineer, invited potential investors to set up a Portland cement plant. Within a year, a cement plant called Cebu Portland Cement (CEPOC), was established. On May 11, 1957, CEPOC, a government-owned corporation, was sold to the privately owned Bacnotan Consolidated Industries (BCI). BCI is the manufacturer of "Union Cement". In 2004, BCI was sold to Holcim Cement.
