The Rising Star is a copper and zinc mine located in Shasta county, California at an elevation of 1,299 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 (Commodity): ORE IS SEPERABLE INTO THREE MAIN TYPES. ONE TYPE IS REPRESENTED BY SPHALERITE IN CONCENTRATIONS CONTAINING AS MUCH AS 20 % ZN, WITH SOME PYRITE AND CHALCOPYRITE. THE CHALCOPYRITE YIELDS AN AVERAGE OF 2 % CU. THE SECOND TYPE IS LARGELY PYRITE WITH SMALLER AMOUNTS OF CHALCOPYRITE AND SPHALERITE. THE THIRD TYPE IS MOSTLY CHALCOPYRITE AND PYRITE, LESS SPHALERITE. GALENA, TETRAHEDRITE - TENNANTITE, CHALCOCITE AND LUZONITE ARE ALSO PRESENT IN THE FIRST AND THIRD TYPES. PYRITE IS NEARLY UBIQUITOUS, LOCALLY IT IS HEAVILY DISSEMINATED AND FORM A HALO AROUND LENSES OF MASSIVE SULFIDE.

Comment (Workings): DEVELOPED BY 6 PRINCIPAL LEVELS

Comment (Geology): GEOL.DESC: RISING STAR ORE BODIES ARE CLOSELY RELATED TO NORTHWESTWARD - TRENDING, STEEPLY DIPPING SHEAR ZONES NEAR CREST OF THE BULLY HILL ANTICLINE WHICH PLUNGES TOWARD THE SOUTH. GEOLOGY SIMILAR TO BULLY HILL AREA.

Comment (Production): CUMULATIVE PRODUCTION TABLE ARE VALUES FROM THE BULLY HILL AND RISING STAR MINES COMBINED.
