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): 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.

Comment (Workings): WORKINGS CONSIST OF AN INCLINED SHAFT, DRIFTS AT THE 100-FOOT LEVEL, AND AN ADIT AT THE LEVEL OF THE COLLAR OF THE SHAFT. STOPING.

Comment (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

Comment (Development): BARONS CONSTRUCTED AN AGITATION LEACH FACILITY AND BEGAN PRODUCTION IN LATE 1986 FROM TAILINGS.
