Comments

Comment (Workings): MINE DEVELOPED BY CROSSCUT ADIT FROM WHICH RAISE IS TO SURFACE AND DRIFT FOLLOWS VEIN ABOUT 500 FT.

Comment (Deposit): THE BIRDIE VEIN IS A MASSIVE QUARTZ VEIN. IT HAS BEEN BRECCIATED AND HEAVILY STAINED WITH FE AND MN OXIDES. VEIN WALLS ARE HIGHLY ALTERED. ON THE MAIN LEVEL, HUEBNERITE CRYSTALS OCCUR IN NARROW BANDS AND SMALL CLUSTERS. A SECOND VEIN INTERSECTS THE BIRDIE VEIN. THE GREATEST CONCENTRATION OF HUEBNERITE OCCURS AT THE INTERSECTION.

Comment (Production): SEVERAL THOUSAND TONS SILVER ORE SHIPPED ABOUT 1900. 82 TONS TUNGSTEN ORE SHIPPED IN 1916

Comment (Deposit): Discovery Year: 1880-SILVER 1907-W
