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 (Production): DURING 1917-1918 THERE WERE REPORTEDLY SEVERAL CARLOADS OF ORE SHIPPED. APPROXIMATELY 900 TONS OF LEAD-ZINC ORE OF GOOD GRADE WAS PRODUCED BETWEEN 1942 AND 1952.

Comment (Workings): WORKINGS CONSIST OF A 300-FOOT SHAFT AND A 405-FOOT DRIFT ON THE 189-FOOT LEVEL. THERE ARE SEVERAL PITS ON THE SURFACE.

Comment (Deposit): ON THE SURFACE THE PENNSYLVANIA VEIN IS TRACEABLE FOR ABOUT 650 FEET. THE VEIN STRIKES ABOUT DUE NORTH ON THE AVERAGE AND DIPS 70 TO 80 W. NEAR THE PENNSYLVANIA SHAFT IT BENDS ABRUPTLY AND THE BEND IS REFLECTED ALSO IN THE COURSE IN THE VEIN UNDERGROUND. IN THE SADDLE SOUTH OF THE MINE, A CONSPICUOUS VEIN IS EXPOSED IN PITS DUG ON THE EAST FLANK OF LUCERAS HILL; THIS MAY BE A FAULTED SEGMENT OF THE PENNSYLVANIA OR A SECOND VEIN. IN THE SURFACE WORKINGS THE VEIN IS A BEND OF LIGHT-COLORED, SOFT, ALTERED, AUGITE-BIOTITE MONZONITE, 1.5 TO 7 FEET WIDE, CONTAINING STREAKS OF LIMONITE AND STRINGERS OF QUARTZ. GREEN BOTRYOIDAL SMITHSONITE WAS FOUND IN THE WEATHERED CAPPING OF THE VEIN. UNDERGROUND, ON THE 189-FOOT LEVEL, THE VEIN IS A THIN, SINUOUS ZONE OF SHEARING AND ALTERATION CONTAINS A BAND OF MASSIVE SPHALERITE AND GALENA LYING IN THE MIDDLE OR ON THE FOOTWALL OR HANGING WALL. STREAKS OF MASSIVE OPALINE QQARTZ ARE LOCALLY INTERLAYERED WITH ORE. IN THE SHAFT BETWEEN THE 189 AND 300-FOOT

Comment (Deposit): LEVELS THE VEIN CONTAINS AN ALMOST CONTINUOUS BAND OF MASSIVE ORE RANGING 6-18 INCHES THICK. THE VEIN IS COVERED BY MINERAL SURVEY 1325 AND FIVE PATENTED CLAIMS (1906) - THE J.B. WEAVER, BOB INGERSOLL, BERTHA MABLE, OWL, AND SURE WINNER.

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