AMIS0566 Cu 21% Au 17.17g/t Conc Didipio Philippines

Origin of Material

The final Cu concentrate is the combined recovery from the flash flotation and fine flotation circuits.
Cu in the concentrate is upgraded to 22-24% from the mill feed ore grade of about 0.4-0.8% Cu.

The Didipio Gold-Copper Project is located in the north of Luzon Island approximately 270km NNE of Manila, in the Philippines. The deposit lies within the Dinkidi stock in the Didipio Igneous Complex, a massive alkalic intrusive body. Regionally, the geology consists of late Miocene aged volcanic, volcaniclastic, intrusive and sedimentary rocks that are hosted above a sequence of pre-tertiary aged tonalite and schist

Approximate Mineral and Chemical Composition

Chalcopyrite and gold are the main economic minerals in the deposit. Chalcopyrite occurs as fine-grained disseminations, aggregates, fracture fillings and stockwork veins, particularly within the vein zone of alteration. Chalcopyrite can replace magnetite and is, in turn, replaced by bornite. Bornite occurs as alteration rims around and along fractures within chalcopyrite grains.
