The Mountain Cedar Prospect is a copper mine located in Snohomish county, Washington at an elevation of 2,749 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 (Location): NEAR HEAD OF SULTAN BASIN ON NORTH SIDE OF NORTH FORK SULTAN RIVER

Comment (Deposit): 2-10 FT WIDE VEIN ALONG SHEAR ZONE. THERE MAY BE TWO PHASES OF MINERALIZATION, A MAGMATIC SULFIDE PHASE DURING CRYSTALLIZATION OF THE ULTRAMAFIC ROCKS WHICH CONCENTRATED SOME OR ALL CU AND NI AND A HYDROTHERMAL PHASE POSSIBLY ASSOCIATED WITH THE INDEX BATHOLITH DURING WHICH THE REMAINING COMMODITIES AND POSSIBLY MORE COPPER WERE CONCENTRATED.

Comment (Workings): OPEN CUTS, ADITS

Comment (Geology): THE DISTRICT CONSISTS OF ACCRETED METASEDIMENTARY ROCKS INTRUDED BY GRANITIC ROCKS AND OVERLAIN BY MARINE STRATA AND YOUNGER VOLCANIC ROCKS

Comment (Commodity): CHROMITE HAS BEEN REPORTED, BUT APPARENTLY NOT VERIFIED
