Comment (Production): SCHEELITE WAS MINED FROM A 40-FT SHAFT 175 FT SW OF MORGAN SHAFT.

Comment (Development): OPERATORS INCLUDED TWIN BUTTES MINING AND SMELTING CO, J.A. POIND EXTER

Comment (Deposit): COPPER MINERALIZATION OCCURS ALONG FRACTURE ZONE, AND EXTENDS DOW N TO 900 FT WHERE MINABLE GRADE ORE RUNS OUT OR GRANITE IS ENCOUNTERED . W ORE OCCURS IN WNW STRIKING QUARTZ FISSURE VEINS THAT EXTEND UP TO 50 FT LONG AND 10 FT WIDE. THESE VEINS OCCUR IN CRET (?) QUARTZITE AND SHALES FOR 600 FT.
