Mine Info

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): Veins in fissure zones in Precambrian granite, and schist and gneiss, trend ENE to east and dip to the north. Silver, and some gold, are the main products sought.

Comment (Location): Shaft is about 1 mile north of Turquoise Lake and 6 miles NW of Leadville, in the SE/4 sec 1, T 9 S, R 81 W.

Comment (Production): Incomplete records credit the mine with almost 1 million oz of silver production. (Sunshine files, 1983)

Comment (Reserve-Resource): Total reserves (mostly inferred) of 120,000 tons of material containing 22 oz/ton silver and 0.06 oz/ton gold. (Sunshine files, 1983)

Comment (Reserve-Resource): MAY BE GOOD IF RADIOACTIVITY IS DUE TO U
