Deposit VEIN WIDTH INCREASES WITH DEPTH BUT WITH DECREASING VALUES. THE FOOTWALL OF THE VEIN IS GENERALLY A WELL-DEFINED SLICKEN SIDED PLANE, BUT THE HANGING WALL IS INDEFINITE. THE ORE BODY CONTAINED MANY SMALL FISSURES AND SMALL SLIP PLANES, AND MOST OF THEM ARE PARALLEL TO THE TREND OF THE ORE BODY, BUT SEVERAL LIE AT ANGLES WITH THE VEIN, GENERALLY COMING IN FROM THE HANGING-WALL SIDE, AND MAKE HORSES OF BARREN MATERIAL. ABOUT 200 FEET EAST OF THE SHAFT STRONG CROSS FISSURES FILLED WITH CALCITE APPARENTLY LIMIT THE ORE. THIS LODE OR VEIN HAS THREE WELL-MARKED DIVISIONS OR LAYERS. ON THE HANGING WALL THERE IS A SOFT LAYER FROM 3 TO 3 1/2 INCHES WIDE, WHICH AVERAGES ABOUT $800 DOLLARS PER TON IN VALUE. NEXT BELOW THIS THERE IS A MIDDLE LAYER OR ORE BODY OF QUARTZ ABOUT 20 INCHES THICK, WHICH WILL AVERAGE $190 TO $200 PER TON IN VALUE. THE REMAINDER OF THE VEIN, SO FAR AS IT IS EXPOSED BY THE SHAFT, AVERAGES ABOUT $24 PER TON.
Deposit PRIMARY PRODUCTION STOPPED IN JULY 1910, BUT INTERMITTENT PRODUCTION CONTINUED THROUGH 1937. CURRENTLY USE CYANADATION MILLING. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
