Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Geology): Steeply-dipping veins in tension fractures, trending NE over a 3000 ft overall strike length. Production to about 900 ft below the surface. Most production from "Main Vein" and "Great Northern Vein." Veins generally strike N35-40E and dip 70-85 NW. Vein widths vary from a fraction of an inch to 14 ft. Most stopes are from 4 to 10 ft wide. Little gangue compared to sulfide material in veins.

Comment (Location): Mine is on the north side of French Gulch, about 1-1/2 miles east of Breckenridge, in SE/4 sec.32, T 6 S, R 77 W; workings extend at least 1/2 mile to NE into sec.33.

Comment (Production): The most productive mine in the district, total output from 1887 to 1928 is about 6,500 oz. of gold, 750,000 oz. silver, 40,700,000 lb. lead, and 164,600,000 lb. zinc. (USGS PP 223)

Comment (Production): The mine has produced about $35,000,000 from 1887 to 1964; lead accounts for about 60% of the value, zinc about 25%, silver about 10%, and gold about 5%. The mine was closed from 1929 to 1948; reopened and produced 49,000 tons ore from 1950 to 1958, and 17,600 tons in 1963. A small amount of cadmium was produced during the most recent operations. (Sunshine files)

Comment (Reserve-Resource): Total possible ore: 480,000 tons estimated in 1964 (file data).

Comment (Workings): Workings on 8 levels include many adits, shafts, and drifts and crosscuts that aggregate more than 12 miles in 1930.
