Gold Skarns

2018-8-22 · The ore in both reduced and oxidized types tends to have low Cu:Au (<2000), Cu:Ag (<1000), Zn:Au (<100) and Ag/Au (<1) ratios. Gold is commonly present as micron-sized inclusions in sulphides, or at sulphide grain boundaries. It is often associated with tellurides. To the naked eye, Au skarn ore is generally indistinguishable from waste rock.
