Red Devil

The Red Devil is a mercury mine located in Alaska at an elevation of 200 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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 (Production): TOTAL OF 36,141 +/- 408 FLASKS HG FROM 1933-71 (MILLER AND OTHERS, 1989).

Comment (Workings): ABOUT 9,600 FEET (3,000 M) OF UNDERGROUND WORKINGS ON FIVE MAIN LEVELS.

Comment (Deposit): ON SW LIMB OF NW-TRENDING SLEETMUTE ANTICLINE.

Comment (Deposit): 'HOST ROCKS ARE INTERBEDDED GRAYWACKE AND SHALE OF THE KUSKOKWIM GROUP CUT BY A FEW DIKES THAT ARE GENERALLY ALTERED TO QUARTZ, CHALCEDONY, CARBONATE, AND SERICITE (MALONE, 1962). MOST OF THE ORE FORMED ALONG AND NEAR INTERSECTIONS BETWEEN ALTERED DIKES AND NW-TRENDING FAULTS THAT MAINLY PARALLEL BEDDING PLANES. FORMATION OF ORE WAS PRIMARILY BY OPEN SPACE FILLING AND CONSISTS OF CINNABAR ASSOCIATED WITH ABUNDANT STIBNITE IN A QUARTZ-RICH GANGUE; LESS COMMON REALGAR, ORPIMENT, AND ANTIMONY MINERALS ARE ALSO FOUND (MACKEVETT AND BERG, 1963). STIBNITE-CINNABAR RATIO INCREASES WITH DEPTH (MALONE, 1962). ORE SHOOTS DID NOT CONTINUE BELOW 460-480 FT (DONALD GRYBECK, USGS, PERSONAL COMMUN., 1988). MACKEVETT AND BERG (1963) REPORTED THAT CLAY MINERALS (DICKITE AMONG THEM) OCCUPY CENTRAL PARTS OF SOME ORE-BEARING VEINLETS, BUT ARE MORE CONSPICUOUS IN BARREN VEINLETS AWAY FROM ORE BODIES. JASPER (1961) STATED THAT WHILE NO NATIVE MERCURY WAS FOUND AT THE PROPERTY, OLD TIMERS REPORTED

Comment (Reserve-Resource): KNOWN ORE BODIES EXHAUSTED

Comment (Location): ON THE S BANK OF THE KUSKOKWIM RIVER ABOUT 6.25 MILES (10 KM) NW OF THE TOWN OF SLEETMUTE.

Comment (Deposit): APPRECIABLE AMOUNTS IN MATERIAL PANNED ALONG MCCALLY CREEK, WEST OF THE PROPERTY.' (MILLER AND OTHERS, 1989).
