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 (Workings): PROPERTY CONTAINS SMALL SHALLOW OPEN-PIT MINE AND STOCK PILES OF REWORKED DUMP MATERIAL FROM OTHER MINESITES IN DISTRICT. FAIRLY MODERN CRUSHING AND SORTING EQUIPMENT PRESENT. OLD CHARCOAL KILNS, (SMELTERS), SEVERAL LEACH? PONDS IN DRAINAGE AND CANISTERS OF SODIUM LSULFISDE AT SITE. SHALLOW SURFACE SCRAPING

Comment (Reserve-Resource): EASILY MINEABLE (OPEN PIT) ORE FROM THE JUMBO SHOOT

Comment (Location): UNSURVEYED ; INFO FROM LAND.ST :1972

Comment (Development): SEVERAL CORE BOXES INDICATE PROPERTY WAS DRILLED. OPEN PIT OPERATION APPEARS TO BE 2.5 YEARS OLD. EQUIPMENT IS MODERN, BUT NO SIGN OF CURRENT ACTIVITY. ORANGE FAGGING ON OUTCROPS AT WEST EDGE OF PIT INDICATES RECENT SAMPLING OF PROPERTY

Comment (Deposit): AREA OF SHEETED QUARTZ VEINS AND QUARTZ-CEMENTED BRECCIA WHICH WAS EMPLACED ALONG ASHEAR ZONE. INTERVENING WALLROCK FRAGMENTS AND LENSES CONSIST OF ALTERED ANDESITE, MAPPED AS MIOCENE ASH-FLOW TUFF. ROCKS ARE HIGHLY ALTERED; FELDSPARS ALTERED TO CLAY. THERE ARE SOME FRAGMENTS OF CONGLOMERATE OR FINE-GRAINED CLASTIC ROCK ALSO. FRAGMENTS OF QUARTZ VEIN, RECEMENTED BY WHITE QUARTZ WERE ALSO OBSERVED, INDICATING MULTIPLE VEINING AND BRECCIATION. THE QUARTZ IN OUTCROP IS LIGHT GREEN TO TAN TO GREY IN COLOR, SUGARY TO MASSIVE IN TEXTURE AND CHARACTERISTICALLY VUGGY WITH SOME GOSSANY PORTIONS. THE VUGS ARE FILLED WITH EUHEDRAL PRISMATIC QUARTZ WHICH IS HIGHLY IRON-STAINED. FISSURE-TYPE BANDING IS COMMON AS IS QUARTZ AFTER CALCITE TEXTURES. SOME COARSE WHITE CALCITE VEIN IS ALSO PRESENT. THE REMNANT MOST ROCK IS THOROUGHLY KAOLINIZED AND SILICIFIED. MOST OF THE VEINS ARE SUBPARALLEL WITH A GENERAL N-NW STRIKE AND SHALLOW E-NE DIP. THE OUTCROP IS SHEARED (FRACTURED) BOTH PARALLEL TO AND AT A

Comment (Deposit): HIGH ANGLE TO THE SHEETED VEIN SYSTEM. THE DOMINANT NW SHEARING AND VEINING REFLECTS A MAJOR NE-STRIKING 30E-DIPPING FAULT WHICH BOUNDS THE INFERRED SOUTHERN LIMIT OF THE CALIENTE CALDRON COMPLEX. SO

Comment (Commodity): BA IS UNCERTAIN.
