Prospectors Edward Knight and Emmet Chase discovered gold in 1933 and located the first claims in 1934. With the financial backing of Noble Getchell and George Wingfield, the Getchell Mine, Inc. was organized in 1936 and the mine was brought into production in 1938.
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 method currently used is underhand cut-and-fill. 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 gold deposit, Carlin–type deposit, with micron, sub-micron sized gold distributed in pyrite and marcasite.
The mineral getchellite, a rare Sulfide mineral, sulfide of arsenic and antimony, AsSbS3, was discovered at and named after the Getchell mine .
