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 (Geology): VEIN IS BARREN FRACTURE IN-FILLED WITH CRUSHED CALCAREOUS SANDSTONE AND QUARTZITE. OREBODIES REPLACED LIMEY BEDS ALONG SHEARED ZONES. FAULTS CONTAIN MASSIVE LIMONITE AND HEMATITE IN PLACES; ALSO VEINLETS OF PARTIALLY OXIDIZED GALENA AND IRON OXIDES.

Comment (Deposit): FIRST CLAIM HERE WAS RECORDED IN 1869. THIS WAS AMONG THE CLAIMS ACQUIRED BY THE FRENCH CO. IN THE EARLY 1880'S IN THE GALENA AREA. PRODUCTION FROM CLAIMS AS A WHOLE WAS GOOD FROM EARLY 1880'S TO 1885, BUT NO INDIVIDUAL FIGURES ARE RECORDED. WORKINGS CONSISTED OF AN 800-FT. DRIFT TO A RAISE, FOLLOWING THE S. EXTENSION OF THE WHITE AND SHILOH VEIN, WHICH IS APPARENTLY BARREN HERE. PRODUCTION, IF ANY, WAS NO DOUBT VERY SMALL ; INFO.SRC : 1 PUB LIT
