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.

Comment (Deposit): CLAIMS INCLUDED CORONA, CORONA NO. 1 AND NO. 2 ; INFO.SRC : 1 PUB LIT

Comment (Workings): CREEK-LEVEL ADIT ON CORONA NO. 1 CLAIM 370-FT. LONG TO NORTH. SOME ORE STOPED ABOVE TUNNEL ABOUT 100 FT. FROM PORTAL, NEAR OLD STOPE. 220 FT. SHAFT WITH LEVELS AT 75, 125 AND 200-FT. 50-FT. LONG ORE SHOOT WAS MINED ABOVE 75 AND 125-FT. LEVELS, FROM RAISE ON 125 FT. LEVEL, CONNECTING TO SURFACE. HANGING WALL CROSSCUT AT 200 FT. LEVEL CUT 8 IN. STRINGER ZONE. AT 42 FT., IT CUT THROUGH 11 FT. OF TALC. SEVERAL OLDER TUNNELS ON NORTH AND SOUTH SIDES OF JAIL CANYON. ON CORONA NO. 2 CLAIM, NORTH OF SHAFT AND ON OPPOSITE SIDE OF RIDGE, VEIN DEVELOPED, 42 FT. VERTICAL SHAFT, 60 FT. S. OF MAIN SHAFT, SUNK ON 2-3 FT. VEIN.

Comment (Commodity): HIGH-GRADE ORE OCCURS AS MASSIVE IRON SULFIDE BANDS. WHERE EXPOSED, THESE BANDS WHERE OXIDIZED AT SURFACE TO LIMONITE, BUT WHEN PIECES BROKEN OPEN, FOUND TO CONSIST ENTIRELY OF UNALTERED SULFIDES. ON OXIDIZED FACES MAY BE SEEN OCCASIONAL SPECKS OF CUPRITE.

Comment (Location): UTM ACC. LOCATION PROJECTED
