Greenhorn Gulch placer camp is gone except for the tiny railroad flag station at Austin. Placers were worked for a distance of twelve miles and drained by the Seven-Mile Creek. The total placer production was estimated at $1,200,000.
Surrounding Austin were lode mines. These mines were worked between 1880 and 1935 and yielded $300,000 in silver, copper, lead, and gold. The value of the ores would flux because the ore contained iron.
