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 (Production): 30 TON AMALGANATION AND CYONIDE PLANT IN 1907; 30 TON ARRASTRA IN 1908
Comment (Geology): CRUSTIFIED EPITHERMAL QUARTZ VEIN, WITH CHALCEDONIC AND COMBQUARTZ, YELLOWISH ARDULARIA, LAMELLAR CARBONATE
Comment (Development): 30 TON AMALGAMATION AND CYANIDE PLANT WAS ON SITE IN 1907; 30 TON ARRASTRA WAS ON SITE IN 1908. NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA HAD BEEN STAKED.
Comment (Workings): SHAFT AS SHOWN ON TOPO, PARTIALLY CAVED AT COLLAR. TRENCHING AND SURFACE EXPLORATION IN VICINITY OF MINE AND ALONG ROAD IS PROBABLY 3-5 YEARS OLD. VERY RECENT (1983) NARROW BACKHOE TRENCH (FOR SAMPLING) ALONG ROAD NORTH OF SHAFT. REMAINS OF ORE CHUTE BELOW MINE.
Comment (Deposit): COCKADE AND DRUSY QUARTZ FORMS ENCRUSTATIONS AROUND ALTERED ROCK FRAGMENTS. WHITE QUARTZ AND SIDERITE VEIN ARE ALSO COMMON, BUT QUARTZ PREDOMINATES. QUARTZ AFTER CALCITE TEXTURES COMMON. PARTIALLY OXIDIZED PYRITE IS COMMON IN BOTH THE VEIN AND THE ALTERED FRAGMENTS. SOME OF THE ROCKS ARE IRON-STAINED AND/OR COATED WITH GREENISH (FE ?, AS ?, CL ? ) OXIDES. ALTHOUGH NO STRUCTURE IS VISIBLE AT THE SHAFT, THE ENTIRE HILLSIDE EAST OF THE MINE IS COVERED BY CRUSTIFIED FISSURE TO MASSIVE QUARTZ VEIN AND QUARTZ-CEMENTED ANDESITE BRECCIA.
