Green-carbonate gold ore from Western Australia

The ore is dominated by carbonate (probably dolomitic or ankeritic, minimally acid-reactive, roughly 62 vol.% of the rock), quartz (30%) and green mica (8%). Accessory minerals include arsenopyrite, chalcopyrite, pyrite and rutile. The ore is relatively low-grade, probably 1.3-1.5 ppm gold, whereas associated `porphyry' ore may grade 5-6 ppm.

Ore genesis Wikipedia

Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults. This may occur without much hydrothermal fluid flow

Quartz Wikipedia

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO 4 siliconoxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
