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): Discovery Year: EARLY 1900'S

Comment (Location): UTM IS FOR SAMPLE SITE 3909, CENTRALLY LOCATED ON THE CLAIM BLOCK. UTM FOR SAMPLE SITE 3912 IS N 4369960, E 405560. ; INFO FROM LAND.ST :(1972)

Comment (Development): M.S. #3153, NOT PATENTED, BUT SURVEYED IN 1907. NO ACTIVITY WHEN EXAMINED IN 1986, BUT NEARBY STAKING BY ERICKSON IN JULY 1979. SIZE OF WORKINGS INDICATE SOME PROBABLE PAST PRODUCTION

Comment (Deposit): LARGE SILICIFIED VEIN, PARTLY BRECCIA-VERY STRONGLY SILICIFIED, FORMED ALONG A FAULT ZONE. THE ZONE INCLUDES A 6-INCH THICK LENS OF LIMONITE-STAINED BRECCIATED QUARTZ VEIN. MOST OF THE WORKINGS REPORTEDLY FOUND VERY LITTLE MINERALIZATION BELOW THE 100 FT LEVEL.

Comment (Workings): DEVELOPED BY 10 CUTS, 4 SHAFTS, 1 CUT AND TUNNEL, 1 CUT & SHAFT (1907) LARGE CROSS-CUTTING ADIT, SHAFTS, STOPE. THE LARGE ADIT WAS DRIVEN FROM THE CANYON EAST OF THE LARGEST WORKINGS, TO THE WEST, FOLLOWING AND UNDERCUTTING THE LARGE SILICIFIED VEIN.
