Comments on the workings information

  • WORKINGS CONSISTED OF 3 OR MORE SHAFTS, AN OPEN CUT, AND A TUNNEL. THE SHAFTS WERE 15, 12, AND 7.6 M (50, 40, AND 25 FT) DEEP RESPECTIVELY, THE DEEPEST SHAFT WAS HIGHEST IN ELEVATION AND THE OTHER TWO WERE SUCCESSIVELY LOWER. THE OPEN CUT IS SOUTHEAST OF THE LOWER SHAFTS AND IS 12 M (40 FT) LONG. THE TUNNEL IS THE LOWEST WORKING AND CONNECTED WITH THE LOWEST SHAFT BY A CROSSCUT. IN 1982 AT LEAST 3 CAVED SHAFTS, 11 PITS, AND OPEN CUT AND 2 CAVED TUNNELS WERE EVIDENT. ORE WAS SEEN ON THE DUMPS, PARTICULARLY AROUND THE LOWER SHAFT, OPEN CUT, AND TUNNEL. THE LARGEST SHAFT IS 4.6 M (15 FT) IN DIAMETER AND 1.2 M (4 FT) DEEP. THE OPEN CUT IS APPROXIMATELY 15 M (50 FT) LONG, 1.8 M (6 FT) WIDE, AND UP TO 1.5 M (5 FT) DEEP.

Comments on development

  • ORIGINALLY THE ORE WAS TO BE MINED FROM THE TUNNEL, FROM THE ADIT OF WHICH A STEEP INCLINE WAS TO BE BUILT TO THE STREAM BELOW AT THE FOOT OF THE MOUNTAIN SLOPE, WHERE A LOG WASHER WAS TO BE INSTALLED. APPARENTLY THIS WAS NEVER DONE AND PRODUCTION NEVER OCCURRED. THE PYROLUSITE WAS SO SOFT THAT IT WAS SIMPLY A COMPACTED POWDER SO THAT IF IT HAD BEEN MARKETED IT PROBABLY WOULD HAVE BEEN SEPERATED BY HAND FROM THE CLAY, CHERT, SAND, AND SANDSTONE.

Deposit THE SHAFTS WERE SUNK IN SANDSTONE AND YELLOW CLAY, AND LIMESTONE WAS REPORTEDLY ENCOUNTERED. SOFT PYROLUSITE WAS ENCOUNTERED IN THE UPPER AND LOWER SHAFTS IN SMALL QUANTITIES, THE 12 M SHAFT YIELDED ONLY STAINS AND MINUTE FRAGMENTS. THE OPEN CUT FOLLOWED AN ORE-BEARING ZONE OF SAND AND SOFT SANDSTONE ABOUT 2.1 M (7 FT) THICK THAT LIES PARALLEL WITH THE BEDDING. THE HANGING WALL OF THE CUT IS A HEAVY GRAY SANDSTONE DIPPING 60 DEG S. PYROLUSITE WITH SOME PSILOMELANE OCCURS IN THE ZONE AS AFISSURE-FILLING IN THE SANDSTONE. THE TUNNEL FOLLOWED AN ORE-BEARING ZONE AS THAT IN THE OPEN CUT, THE ZONE DIPS SOUTHWEST AND THE SAND AND SANDSTONE CONTAIN IRREGULAR VEINS OF PYROLUSITE WHICH LOCALLY SWELL TO 20 CM (8 IN) THICK. IT IS OVERLAIN BY SANDSTONE AND UNDERLAIN BY CHERTY CLAY AND YELLOW CLAY IN WHICH VERY LITTLE MANGANESE WAS FOUND. GRAY GRANULAR LIMESTONE WAS ENCOUNTERED IN THE SHAFT AT THE END OF THE CROSSCUT. THE YELLOW CLAY AND CHERT WERE DERIVED FROM THE NEW SCOTLAND (?) LIMESTONE.
