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 (Production): SOME ANTIMONY ORE WAS SHIPPED IN THE 1880'S.

Comment (Location): FENCEMAKER CANYON

Comment (Deposit): Discovery Year: 1880'S OR BEFORE

Comment (Deposit): CINNABAR OCCURS WITH WHITE CALCITE AND CHALCEDONY VEINLETS IN GRAY LIMESTONE, QUARTZ SANSTONE AND OLIVE SILTSTONE (BASED ON A FEW DUMP SPECIMENS). THE WORKINGS FOLLOW EAST-WEST FAULT AND GOUGE ZONES WHICH APPEAR NEARLY VERTICAL. THE ROCKS ARE LOCALLY SLIGHTLY SILICIFIED AND IRON-STAINED. BAILEY ET AL (1984) REPORT THAT THE SHEARS DIP STEEPLY NORTHWARD. SPECIMENS OF BROKEN, IRON-STAINED QUARTZITE ON THE DUMP CONTAIN CINNABAR IN CRYSTALS AS MUCH AS 1 MM IN DIAMETER ASSOCIATED WITH ABUNDANT QUARTZ VEINLETS.; MODEL NAME COULD ALSO BE: SIMPLE SB.

Comment (Workings): 2 ADITS, OPEN CUT, BULLDOZER CUTS

Comment (Geology): STIBNITE OCCURS IN FRACTURES AND FAULTS ALONG THE CONTACT BETWEEN LIMESTONE AND A DIABASE DIKE, AS SMALL PODS, STREAKS, ROSETTES, AND INDIVIDUAL CRYSTALS. STIBNITE IS DISSEMINATED THROUGH THE LIMESTONE IN THE END OF THE EAST CROSS CUT FROM MAIN ADIT. CINNABAR ALSO OCCURS AS SCATTERED BLEBS AND SINGLE CRYSTALS.

Comment (Development): SOME SB ORE WAS SHIPPED IN THE 80'S, AND THEN THERE WAS NO MINE DEVELOPMENT UNTIL 1940. THIS IS PERHAPS THE PROPERTY FROM WHICH JACK MCCORDNEY AND HARRY MOBLEY PRODUCED SOME MERCURY IN 1964.
