Mineralogy of Stikine Copper's Galore Creek deposits

Mineralization at Galore Creek consists mainly of disseminated chalcopyrite, bornite and pyrite. Biotite and orthoclase are the dominant alteration minerals with commonly associated anhydrite, garnet, apatite, calcite and magnetite. The mineralization occurs in altered syenites, metavolcanics and b...
