A former underground Au-Cu-Mo-Pb mine located in sec. 26, T8S, R16E, on private land. This was a gold mine started about 1881, and is next to the Mammoth property on the West. It was leased in 1894 by Johnston, Barnhart, and Collins, who, up to the end of 1895, mined more than 40,000 tons of ore from above the 300 level. The Mammoth Gold Mining Co. acquired the Collins Mine in 1898 and operated it as the Mammoth-Collins Mine for 4 years. Also known as / designated: St Anthony Mining and Development Co. property; Great Western Copper Co. property; Collins property.
During April, 1901, a large stoping area at the North end of the mine suddenly caved from the surface to the 750 level and caused about an acre of the surface to subside for some 35 feet. The hill behind Tiger in old photographs bears the gap in the hill as a result of this cave-in. The gap is still there today. Subsequently the property was consolidated with, and subhumed by the Mammoth-St Anthony Mine.
Mineralization is the Collins vein, that dips steeply southwestward. With approximately the same strike, but steep northeastward dip, the Mammoth fault comes to the surface near the Collins vein, and, southeast of the Collins adit, transects its outcrop. Oxidation is rather complete to the 650 level. The orebody between the tunnel level and the 226 level ranged from 110 to 160 feet long by 5 to 30 feet wide.
