Getchell Mine
The mining operation currently consists of two underground mines, Getchell and Turquoise Ridge, operated as the Turquoise Ridge Joint Venture. Barrick Gold is operator and 75% owner with Newmont Mining owning the remaining 25%. The mining methods currently used are cut-and-fill and long hole stoping. The refractory gold ore is treated by pressure oxidation technology at the Twin Creeks Sage autoclave and gold recovered using conventional carbon-in-leach technology.
The gold deposit is a sediment-hosted disseminated Carlin–type deposit, with sub-micron sized gold distributed in pyrite and marcasite.
The mineral getchellite, a rare sulfide of arsenic and antimony, AsSbS3, was discovered at and named after the Getchell mine.
