A Au-Ag placer deposit located in Kentucky Gulch, which heads SSE of Granite Mountain and joins Boston Gulch at Kentucky Camp. Owned at times, or in part, or in places by the Stetson Co.; the El Oro Mining Co.; and the Greaterville Dredge Gold Mining Co.
Mineralization is mostly coarse flake and nugget gold with minor combined silver and some attached galena in medium-sized gravel along recent and older buried channels and terraces close to the mountain front. The gold occurs throughout its length on bedrock in a channel 6 to 10 feet in width. At the upper end of the gulch, the pay streak lay at the surface, but the covering gradually thickens to 6 feet (2 meters) at the mouth of the gulch.
Major operations were undertaken from 1875 to the early 1900's and small and sporadic since then. Estimated production for the entire area is some 30,000 oz. of gold, or more, with about 6,000 oz. of silver.
