| 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. |
