A Pb-Ag-Cu-Zn-Au mine located in T.21S., R.15E., in the east end of the Mansfield property, on the Sweet claim, in Manfield Gulch, at an elevation of 4,700 feet.
Mineralization is the south vein of a large lode or mineralized zone, which strikes N.70ºE. and dips 80ºS., in the reddish medium-grained quartz monzonite. The dominant structure in the monzonite dips 35ºE. Rhyolite is intruded near by on the north, and is in general light gray and vitrophyric, but in part pale grayish and reddish-brown. It is tuffaceous and contains fragments of a coarse altered granitoid rock. It is traversed by a coarse sheeting which dips 60ºW.
The vein is about 6 feet wide and contains some ferruginous copper ore, which carries principally pyrite, chalcopyrite, and a little galena in a white quartz gangue.
Workings include the 360 foot deep Sweet with levels at 100 foot intervals starting at the 150 level (+ 250 & 350 levels). Worked intermittently from 1879 through 1951. The group produced some 370 tons of ore averaging about 19% Pb, 22 oz. Ag/T, 2% Cu, and 0.1 oz. Au/T.
