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 (Deposit): WORKINGS ARE LOCATED ON A SHEAR ZONE IN A CONTINUOUS LINE EXTENDING FOR ABOUT 100 FT ALONG STRIKE. ROCKS IN THE ZONE ARE NOTABLY FRACTURED AND IN PLACES COMPLETELY ALTERED TO CLAYS (ARGILLIZED). EPIDOTE AND CU AND FE OXIDES ARE ABUNDANT IN THE ZONE AS COATINGS ON FRACTURE SURFACES. IRREGULAR LENSES OF HIGHLY FE-STAINED, DENSE, SILICIFIED MATERIAL WITHIN THE ZONE IS COMPOSED OF PODS OF MAGNETITE, PSILOMELANE, SPECULARITE, AND ABUNDANT CU MINERALS, MAINLY MALACHITE AND CHRYSOCOLLA WITH MINOR AZURITE. A SAMPLE OF THIS TYPE OF MINERALIZED ROCK WAS COLLECTED FROM THE DUMP. YELLOW AND GREEN OXIDES CHARACTERIZE THIS ZONE AND MAY BE AMIXTURE OF CU MINERALS, FE PO4, EPIDOTE, OR OTHER ALTERATION PRODUCTS. ADJACENT TO THE FRACTURED, MINERALIZED ZONE, THE INTRUSIVE IS BLEACHED, SLIGHTLY SILICIFIED, AND EPIDOTIZED OR CHLORITIZED ALONG FRACTURES. SOME OF THE INTRUSIVE DISPLAYS CROSS-CUTTING FE AND MAGNETITE VEINLETS LESS THAN 1 INCH IN WIDTH.

Comment (Workings): 2 SHAFTS AND CONNECTING SHALLOW STOPES. ONE SHAFT IS SHALLOW AND CAVED, OTHER SHAFT IS ABOUT 15-20 FT DEEP AND INCLINED TO THE SE

Comment (Geology): SOME PINK RHYOLITE FOUND AS FLOAT NEAR WORKINGS

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA IS CURRENTLY STAKED

Comment (Location): INFO FROM LAND.ST :1972
