65 miles east of Gardiner. Pb, Ag, Cu, Au.
"The New World Au-Cu-Ag deposit is actually comprised of 5 separate deposits, including the Como, Fisher Mountain, McLaren, Miller Creek and Homestake deposits. The ore deposits are developed in skarns and replacement zones at sedimentary-rock contacts with four intrusive complexes and in breccia complexes where entrained blocks of limestone have been selectively mineralized. The principal ore mineral is native gold, which occurs as inclusions within pyrite and chalcopyrite and as particles along fractures and grain boundaries, with associated magnetite and specularite mineralization."
