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 (Deposit): A 50-TON/DAY FLOTATION MILL WAS BUILT IN 1918. MOST ADITS HAVE HEADINGS OF N35E. THE VEIN WAS MINED FROM SEVERAL LEVELS OVER A VERTICAL DISTANCE OF ABOUT 500 FEET AND ALONG STRIKE FOR ABOUT 400 FEET. SEVERAL RAISES CONNECT THE DIFFERENT LEVELS OF THE MINE (MOEN, 1980, P. 72). ; INFO.SRC : 1 PUB LIT
Comment (Geology): THE ORE IS IN ALTERED AND SILICIFIED VOLCANIC ROCKS OF THE EOCENE KLONDIKE MOUNTAIN FORMATION. (THE GEOLOGY HERE IS SIMILAR TO THAT DESCRIBED FOR THE AMERICAN FLAG MINE).
Comment (Location): IN A SMALL GULCH 1 MILE NORTH OF THE EAST FORK OF TORODA CREEK.
Comment (Production): BETWEEN 1906 AND 1919, SHIPMENTS OF HIGH-GRADE GOLD-SILVER ORE WERE MADE TO SMELTERS. IN 1918 A 50-TON/DAY FLOTATION MILL WAS BUILT AT THE MINE, AND CONCENTRATES AVERAGING AS MUCH AS 300OZ/TON AG WERE SHIPPED UNTIL 1920. FOR THIS PERIOD, THE MINE PRODUCTION WAS ESTIMATED AT $60,000 TO $100,000 (MOEN, 1980, P. 72).
