Comment (Commodity): GOLD IS ROUNDED AND FLAKES. NUGGETS ARE RARE. RARE WIRE GOLD SUGGESTS A SHORT TRANSPORT DISTANCE. REPORTED PT IS WITHIN DMEA PROPERTY
Comment (Location): LOCATION GIVEN IS ON ROCK CREEK AT ATLANTIC CITY. DMEA PROPERTY LIES NORTHWEST OF THERE AT APPROX 42-29N, 108-39W. ROCK CREEK IS AT THE SOUTHEAST END OF THE WIND RIVER RANGE
Comment (Production): ESTIMATE OF GOLD PRODUCTION IS PROBABLY LOW
Comment (Deposit): LODES CONTAINING AU AND FE ARE PRESENT IN DISTRICT. RICHEST GRAVEL IS 1 MI BELOW ATLANTIC CITY NEAR A LARGE FAULT THAT CROSSES ROCK CREEK. NO GOLD IS FOUND IN GRAVEL THAT OVERLIES SCHIST, ONLY THAT THAT OVERLIES AMPHIBOLITE. GOLD IS FOUND WITHIN 1-3 FT OF BEDROCK
Comment (Workings): DREDGING
