Comments on the location information

  • APPROXIMATELY 0.4 KM (0.25 MI) SW ON STATE ROAD 713 FROM ITS INTERSECTION WITH STATE ROAD 600: TURN NORTHWEST ON DRIVEWAY FOR 0.6 KM (0.4 MI) TO HOUSE: PROSPECT IS LOCATED 70 M (230 FT) NORTH OF THE HOUSE ON THE EAST SIDE AND DOWNHILL FROM THE KENNEL. A SECOND LOCATION IS ACROSS THE CREEK ABOUT 90 M (295 FT) TO THE NORTH AT UTM COORDINATES N 4319510, E 714640, ZONE +17: ELEV. 361 M (1185 FT).; PREVIOUS QUAD DESIGNATION = WARDENSVILLE (1965) 1:24000

Commodities

Commodity Importance
Manganese Critical Primary
Iron Primary

Comments on the commodity information

  • MN ORE WAS MIXED WITH IRON OXIDE AND PHOSPHOROUS: THE LARGE AMOUNT OF IRON, IF IT COULD NOT BE REMOVED, WOULD BAR ITS USE FOR CHEMICAL PURPOSES AND THE PRESENCE OF PHOSPHOROUS WOULD PROHIBIT ITS USE FOR METALLURGICAL PURPOSES.

Materials information

Materials Type of material
Limonite Ore
Pyrolusite Ore
Chert Gangue

Analytical data

Result NO ANALYSES AVAILABLE BUT ORE WAS REPORTED TO CONTAIN 1.3 PER CENT OR MORE OF PHOSPHOROUS.

    Length 90M

Comments on the workings information

  • THE NORTH TUNNEL FOLLOWS THE STRIKE OF THE MINERALIZED ZONE 18 M (60 FT), AND A LOWER PARALLEL DRIFT, REACHED BY A SLOPE 11 M (35 FT) LONG DOWN THE DIP OF THE BED, WAS SAID TO GO IN 61 M (200 FT). IN 1981, TWO CAVED TUNNELS, SEVERAL PITS AND DUMPS WERE VISIBLE. THE SOUTH TUNNEL FOUND IN 1981 IS NOT MENTIONED IN THE LITERATURE AND NOTHING IS KNOWN OF ITS DIMENSIONS OR ADDITIONAL WORKINGS. TUNNEL ENTRANCE WAS OPENED BY PROPERTY CARETAKER WHO REPORTED COOL AIR COMING OUT, INDICATING THE TUNNEL IS STILL OPEN FARTHER INSIDE.

Comments on development

  • 2 TUNNELS WERE DRIVEN INTO THE HILLSIDES, ONE ON THE NORTH SIDE AND ONE ON THE SOUTH SIDE OF THE CREEK. 70 TONS OF MANGANESE ORE IS SAID TO HAVE BEEN REMOVED FROM THE NORTH TUNNEL AND PLACED ON THE DUMP AT THE EDGE OF THE RUN, BUT MOST OF IT HAS BEEN WASHED AWAY. APPARENTLY NO ORE WAS SHIPPED.

General comments

Subject category Comment text
Deposit THE ORE IS IN CHERT BEDS 0.3 TO 0.6 M (1 TO 2 FT) THICK SEPARATED BY THIN SANDY CLAY BEDS. AT THE ENTRANCE THE ORE IS CHIEFLY LIMONITE BUT IN DEPTH IT WAS REPORTED TO BE CHIEFLY MANGANESE OXIDE WHICH FILLED CREVICES AND SEAMS IN THE CHERT, AND PARTLY REPLACED IT, AND IN THE CLAY.
