Comments

Comment (Location): UNSURVEYED.

Comment (Deposit): QUARTZ VEIN RESEMBLES THAT FROM INDIANA AND GOLDEN ARROW MINES AND CONTAINS NARROW BLACK STRINGERS OF FINELY DIVIDED PYRITE, SPHALERITE, AND GALENA. SEVERAL VEINS ARE 3-6 FT WIDE WITH SLATE FOOTWALL AND PORPHYRY HANGING WALL. 600 FT N OF CABIN IS A 44 IN. VEIN OF MASSIVE WHITE QUARTZ CONTAINING MARCASITE, MINOR SPHALERITE, AND PYRITE. AN ADIT FOLLOWS VEIN E FOR ABOUT 45 FT, WHERE VEIN PINCHES TO 14 IN. 300 FT S OF THIS VEIN IS A SIMILAR 10-IN. QUARTZ VEIN.

Comment (Workings): 400 FT CAVED ADIT, 45 FT ADIT, OPEN CUT.
