Comments

Comment (Deposit): THE VEIN BELONGS TO THE BLUE VEIN SYSTEM. THE VEIN ON THE 100 FT LEVEL WIDENS FROM A STRONG CLAY WALL TO A BREADTH OF 12 FT, FORMING AN ORE SHOOT THAT WAS DRIFTED ON FOR 100 FT (1905). THE FOOTWALL AND HANGING-WALL BANDS ARE RICH IN SULPHIDES AND QUARTZ, AND BETWEEN THEM ARE NUMEROUS BANDS OF FAIR DEFINITION.
