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 (Location): INFO FROM LAND.ST :(1971)

Comment (Reserve-Resource): VEIN WAS NOT DEPLETED IN 1906 SO IT IS LIKELY THAT SOME LOW-GRADE (PERHAPS 5 TO 10 TOZ/ST AG) SULFIDE ORE REMAINS BUT VEIN WIDTH OF ONE FOOT OR LESS AND DEPTH OF 300 FT. BELOW SURFACE MAKES EXTRACTION EXPENSIVE

Comment (Production): TOTAL PRODUCTION ABOUT $100000.

Comment (Deposit): LOWER TUNNEL HAS LOW GRADE ORE. OXIDIZED ORE IS SAIDTO CARRY A NOTABLE AMOUNT OF PB CARBONATE WITH SOME PYROMORPHITE AND WIRE SILVER. BETTER GRADE SULFIDE ORE OCCURS FROM 200-300 FT BELOW SURFACE.

Comment (Workings): VEIN DEVELOPED BY FOUR ADITS DRIVEN INTO THE SIDE OF A HILL, THE LONGEST OF WHICH FOLLOWS THE VEIN FOR 600 M.
