A Ag-Pb-Ba-Au-Cu-Mo-F mining district locted in T8-9S, R14-15W, in the Mohawk Mts.

Mineralization is: (1): spotty lead sulfide, siliceous silver, and weak oxidized copper mineralization, in quartz veins in fault and breccia zones cutting Mesozoic schist and granitic gneiss.; and, (2) Lensing barite with minor fluorite in veins in Mesozoic gneiss.

Workings include small prospects and mines worked intermittently since the early 1900's. The total production of base and precious metals would be some 61 tons of ore containing about 21,346 oz. of silver, 11 tons of lead, and minor copper and gold. Some 18 cars of barite ore have been produced.
