Comments on the workings information

  • 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.

Comments on 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

General comments

Subject category Comment text
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.
Deposit Discovery Year: EARLY 1900'S
