Formula: Mg5Al(AlSi3O10)(OH)8
Formula: (CaCa)(AlAlAl)O[Si2O7][SiO4](OH)
Formula: Cu
Formula: (Mg,Fe)2Al3(AlSi5O18)
Colour: Grey-blue, greenish.
Description: Occurs in most of the garnet-biotite-quartz rocks as anhedral grains containing numerous biotite inclusions. In hand specimens colour is grey-blue however in areas where hydrothermal alteration has occurred the mineral becomes greenish.
Formula: CuS
Description: Considered very rare and restricted to zones of late hydrothermal activity. Covellite along with goethite are commonly developed in supergene replacement ores.
Formula: Cu2O
Colour: Red
Description: Cuprite as bright red inclusions with native copper has been qualitatively identified as copper oxide presumed cuprite (personal comment to author - Mineralogical Record 22(3)).
Formula: Cu9S5
Description: Is found only as ex-solution lamellae in association with chalcocite and clausthalite.
Formula: (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH)
Colour: Emerald-green to yellow-green & lime-green
Description: A common hydrothermal mineral in the ore lodes. They can partially coat the quartz or as isolated lath-like inclusions. It's been observed that light coloured apple-green variety associated with chlorite, calcite and albite is common in the Emery lode (Artonvilla mine). A second occurrence in the lower sections of the lode consists of bright lime-green to yellow-green crystals and have lower refractive index to the apple-green variety although both have been identified by x-ray analyses. Epidote fills vugs or is attached to quartz is usually less than 1cm length. Single crystals can reach over 5cm.
Formula: α-Fe3+O(OH)
Colour: Reddish.
Description: Observed as the most common iron mineral in the more central sections of the orebodies, characterized by reddish colour in hand specimens.
Formula: Fe2O3
