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): LOCATION GIVEN BY PETERSON, 1976

Comment (Production): BOTH AUTHORS REPORT SMALL PRODUCTION BUT GIVE NO FIGURES

Comment (Development): 20 FT SHAFT AND A 70 FT ADIT. PROPERTY WAS ORIGINALLY DEVELOPED AS A MOLYBDENUM PROSPECT, BUT DURING WORLD WAR II, IT WAS FOUND TO CONTAIN SCHEELITE. PRODUCTION HAS BEEN SMALL.

Comment (Deposit): SCHEELITE AND MOLYBDENITE ARE DISSEMINATED IN A TACTITE ZONE FLANKING AN APLITE DIKE. APLITE DIKE IS VERTICAL AND CUTS A SILL OF THE GRANITIC NOTCH PEAK INTRUSION AND SURROUNDING LIMESTONE. TACTITE ZONE DOES NOT EXTEND MORE THATN 18 CM FROM THE APLITE DIKE. SOME MOLYBDENITE OCCURS IN QUARTZ VEINLETS ALONG THE EDGES OF THE DIKE. SOME MOLYBDENITE, SCHEELITE, PYRITE, AND MINOR CHALCOPYRITE ARE DISSEMINATED IN TEH APLITE DIKE. MINERAL ASSEMBLAGE IS TYPICAL OF TUNGSTEN SKARN DEPOSITS: W + MO + ZN + CU.

Comment (Workings): WORKINGS CONSIST OF A 70-FT LONG ADIT AND A 20-FT DEEP SHAFT.

Comment (Geology): NO INFORMATION GIVEN ON THE STRIKE OF THE APLITE DIKE. APLITE DIKE IS PRESUMABLY SLIGHTLY YOUNGER THAN NOTCH PEAK INTRUSION.
