NOTE:
Resource potential for Coal Regions (except Bukidnon, Maguindanao, Sarangani, South Cotabato and Sultan Kudarat) are based onRobertson Research International Ltd., 1977 evaluation Positive, Probable, In-situ and Mineable Reservesfor Coal Regions (except Cagayan & Semirara) are based on the verified reserves in Coal Operating Contract (COC) areas and Small Scale Coal Mining Permit (SSCM) applied areas, using DOE standard computatlon; including the submitted report on production of COCs & SSCMPs Total Reserves for Cagayan are based on COCs and R-P German computation Total Reserves for Semirara are based on Semirara Mining and Power Corporation's computation in Molave, Narra & Himalian Mine in COC No. 5
