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 (Deposit): TIN WAS DISCOVERED IN 1914 DEVELOPEMENT CONSIST OF A 50 FOOT DEEP INCLINED SHAFT. THIS SHAFT FOLLOWS THE DIP OF FOUR NEARLY PARALLEL VEINLETS. SEE FRIES (1944) FOR GEOLOGIC MAP OF THE PROSPECT ; INFO.SRC : 1 PUB LIT

Comment (Development): TIN DISCOVERED IN 1914; INCLINED SHAFT SUNK 50 FEET

Comment (Deposit): 4 NEARLY PARALLEL VEINLETS; CASSITERITE-BEARING QUARTZ VEINLETS, LENSES, AND FRACTURE COATINGS

Comment (Workings): INCLINED SHAFT

Comment (Geology): THE TIN DEPOSITS CONSIST OF CASSITERITE BEARING QUARTZ VEINLETS, LENSES AND FRACTURE COATINGS IN RHYOLITE ALONG AN EAST TRENDING BELT ABOUT 2 MILES LONG AND 1/2 MILE WIDE. THE WALL ROCKS ARE UNALTERRED, AND THERE IS LITTLE BRECCIATION AS THE FRACTURES ARE DISCONTINUOUS AND UNDERWENT INSIGNIFICANT MOVEMENT. THE VEINLETS HAVE AN OPEN TEXTURE AND APPEAR AS INCRUSTATIONS OF THE WALLS OF CROSS AND PARALLEL FISSURES. THE INCRUSTATIONS ARE LARGELY SPECULARITE AND CASSITERITE
