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 (Workings): WORKINGS CONSIST OF SIX SHALLOW CUTS AND A PIT 50 TO 60 FEET DEEP A FEW YARDS NORTH OF THE SHAFT. THE SHAFT IS REPORTED TO BE 220 FEET DEEP. ON THE 160-FOOT STATION DRIFTS EXTEND 125 FEET NORTHEAST AND 175 FEET SOUTHWEST. THE VEIN WAS STOPED FROM THE DRIFT UPWARD TO THE BOTTOM OF THE OXIDIZED ZONE, 120 FEET BELOW THE SURFACE.

Comment (Deposit): THE VEIN CROSSES A LOW KNOLL OF HORNBLENDE MONZONITE PORPHYRY SURROUNDED BY GRAVEL AND SAND OF THE ANCHA FORMATION. THE VEIN IS COMPOSED LARGELY OF ALTERED PORPHYRY AND QUARTZ, STAINED WITH LIMONITE. THE WALLS ARE HIGHLY ALTERED AND SHEETED PARALLEL TO THE VEIN. MOST OF THE DUMP MATERIAL IS QUARTZ, ANKERITE AND FERRUGINOUS RHODOCROSITE, WITH SPECKS AND BANDS OF SPHALERITE, GALENA, AND PYRITE. SMALL QUANTITIES OF MALACHITE ARE PRESENT; HARD STEEL-GRAY PSILOMELANE, PRODUCED THROUGH OXIDATION OF THE MANGANIFEROUS CARBONATE, FORMS BOTRYOIDAL CRUSTS ON SOME OF THE ORE.

Comment (Location): LOCATION IS ACCURATE FOR THE SHAFT. ; INFO FROM LAND.ST :1979

Comment (Production): THERE ARE NO ACCURATE PRODUCTION FIGURES AVAILABLE. ELSTON (1967, P. 34-35) REPORTS TOTAL COMBINED PRODUCTION FOR ALL MINES IN THE DISTRICT.
