This MCB deposit is not in some new mining province there has been mines in the area going back a long time.
These deposits below are adjoining this new discovery that CLA has aquired these other mines were closed in the 1980s. Held by a government entity ?

GEOLOGY

The Batong Buhay is underlain by basalts, quartz diorite to tonalite porphyries and dacitic rocks. The basalts are generally propylitic but also exhibit localized advanced argilllic alteration near the intermediate intrusives and major structures. The northeast-trending quartz diorite-tonalite porphyries occur as mini-stocks intruding the basalts. The quartz diorite-tonalite porphyries are magnetite-chalcopyrite-bornite bearing with potassic alteration overprinted by sericite-day-chlorite alteration. The dacitic rocks are generally weakly phyllic-altered and shows localized advance argillic alteration near the intrusives.

III. MINERALIZATION

Two significant mineralization styles were recognized at the Batong Buhay area namely, porphyry copper-gold and high sulphidation quartz-enargite gold vein mineralization. The high sulphidation-type mineralization and associated advance argillic alteration was observed to be superimposed on the earlier porphyry Cu-Au mineralization and alteration.

PORPHYRY CU-AU

At least two porphyry Cu-Au orebodies are found in the area. These are the Dickson and Malinao orebodies. These deposits are mainly hosted by sericite-day-chlorite-altered quartz diorite to tonalite porphyry.

The Dickson porphyry Cu-Au deposit has a high grade core with a diameter of 220 m and average assays of 1.43% Cu and 1.33 gpt Au, enveloped by an outer shell of 0.5% Cu. At the surface, the deposit shows primary chalcopyrite and secondary chalcocite+covellite+malachite mineralization. The Malinao orebody is roughly tabular in shape with dimensions of 800 m by 250 m. The primary copper mineral is chalcopyrite which is altered to secondary chalcocite, malachite and azurite.

HIGH SULPHIDATION QUARTZ-ENARGITE GOLD VEINS

There are gold-rich quartz veins encountered north and south of the Dickson and Malinao orebodies. These veins trend NS to NNW with widths ranging from 1 to 9 m. The veins are vuggy, chalcedonic and contain chalcopyrite, enargite, covellite and tennantite. The vein is hosted in advance argillic altered tonalite porphyry and basalt

The mine produced 926,478 DMT at a mine head of 1.25% Cu for the year 1984
