| Deposit | SURFACE STRIPPING DISCLOSED A ZONE OF CLOSELY SPACED LENSES OF BEMENTITE, WITH SMALL AMOUNTS OF HAUSMANNITE ENCLOSED IN BASALT. THESE LENSES AVERAGED 4 FT WIDE AND 2.5 FT THICK AND EXTENDED FOR A STRIKE LENGTH OF 300 FT. THE ZONE STRIKES NORTHWEST AND DIPS 30 TO 35 SW. AN INCLINED SHAFT WAS SUNK BY THE BUREAU OF MINES IN 1940 NEAR THE LOWER END OF THE DEPOSIT AT AN APPROXIMATE ELEVATION OF 2,912 FT. THIS SHAFT FOLLOWS THE MANGANIFEROUS RED-LIMESTONE BED DOWN DIP FOR 154 FT. THE THICKNESS OF THE LIMESTONE IS FAIRLY CONSTANT EXCEPT FOR VARIATIONS DUE TO FAULT OFFSETS. MOST OF THE MANGANESE MINERALS ARE IN THE LOWER MEMBER OF THE RED LIMESTONE, BETWEEN OVERLYING PILLOW BASALT AND UNDERLYING BASALTIC TUFF. IN SEVERAL PLACES THE ACTUAL DIP OF THE ORE ZONE HAS BEEN STEEPENED BY NORMAL FAULTS. INDIVIDUAL OFFSETS RANGE FROM A FEW INCHES TO MANY FEET. AT 35 FT FROM THE BOTTOM OF THE SHAFT TWO MINERALIZED ZONES, EACH 2.5 FT THICK, HAVE CONVERGED TO FORM ONE ORE BODY. ABOUT 6 IN. OF RED |
| Deposit | LIMESTONE SEPARATES THE ORE FROM THE TUFF FOOTWALL, WHEREAS 3 FT OF RED LIMESTONE SEPARATES THE ORE FROM THE BASALT ABOVE. THE STEEP ATTITUDE OF THE ORE 20 FT FROM THE SHAFT BOTTOM IS THE RESULT OF DRAG BETWEEN TWO PARALLEL FAULTS. FOR THE BOTTOM OF THE 154-FT INCLINE REVEAL MANGANIFEROUS MATERIAL 1.5 TO 2 FT THICK |
