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 (Geology): THE DEPOSIT OCCURS IN THE PETACA SCHIST MEMBER OF THE ORTEGA QUARTZITE.

Comment (Location): LOCATION IS ACCURATE FOR THE MAIN PIT. ; INFO FROM LAND.ST :1979

Comment (Production): JAHNS ALSO REPORTS PRODUCTION DURING 1920 TO 1925 OF SEVERAL HUNDRED POUNDS BISMUTITE, AND PROBABLY AS MUCH AS 5,000 POUNDS OF COLUMBITE, SAMARSKITE AND MONAZITE.

Comment (Deposit): THE DEPOSIT LOOKS LIKE A BOOMERANG IN PLAN VIEW. THE BROAD WEST LIMB TRENDS EAST-WEST AND DIPS STEEPLY SOUTH. THE NARROW SOUTH LIMB STRIKES N 15 E AND DIPS STEEPLY WEST.
