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 (Workings): 700-FT CROSSCUT TUNNEL & SHAFT

Comment (Deposit): 1935, P 38-9) ; INFO.SRC : 1 PUB LIT

Comment (Development): 400 ACRE CLAIM GROUP.

Comment (Production): SMALL PRODUCTION ($5000 WORTH) INCLUDED SOME GOLD.

Comment (Deposit): VEIN & BRECCIA FILL.

Comment (Geology): BLEACHED, SILIFIED QUARTZITE, DISSEMINATED PYRITE

Comment (Deposit): DEVELOPMENT STARTED ON THIS PROPERTY IN 1912, AND CONTINUED AT INTERVALS ON A SMALL SCALE. THE GROUP OF CLAIMS COMPRISES 400 ACRES. IT IS DEVELOPED MAINLY BY A 700-FOOT CROSSCUT TUNNEL AND SHAFT. THE MINE IS ABOUT 2 MILES FROM THE GRANODIORITE CONTACT. THE FIRST 200 FEET OF THE TUNNEL IS IN TERTIARY LAKE BEDS (WHICH OVERLAY THE PALEOZOIC ROCKS ON THE LOWER SLOPES), AND THE NEXT 500 FEET IN A BRECCIA OF DARK-BROWN PALEOZOIC LIMESTONE AND QUARTZITE, WHICH BECOMES MORE SILICEOUS TOWARD THE FACE. ALSO, NEAR THE FACE THE TUNNEL INTERSECTS A 20-FOOT PORPHYRY DIKE. AT 40 FEET FROM THE FACE OF THE TUNNEL OCCURS A 2 1/2 FOOT QUARTZ VEIN DIPPING 40W TOWARD THE PORTAL. IT CARRIES A LITTLE GOLD AND SILVER. AT VARIOUS POINTS THERE ARE OTHER STREAKS WITH A LITTLE PBCO3 AND COPPER STAIN AND SOME SMALL POCKETS YIELDING GOOD SPECIMENS OF QUARTZ, MALACHITE, AND COPPER OXIDE. SEVERAL TONS OF ORE ON THE DUMP AVERAGES 20% CU AND 20 OZ/TON AG. AT THE SHAFT THERE IS SAID TO BE A 4 FOOT VEIN. (SCHRADER,
