Comments on the production information

  • A LITTLE ORE WAS MINED ABOUT 1898. PRODUCTION FIGURES SUBMITTED BY OWNER REPORTED YIELDS OF 82 LONG TONS IN 1916, 20 TONS IN 1917, 424 TONS IN 1918. LATTER FIGURE APPEARS RATHER HIGH UNLESS IT INCLUDES SOME ORE OF MILLING-GRADE AS INVESTIGATOR REPORTED THAT ONLY 300 TONS OF SHIPPING GRADE ORE HAD BEEN MINED AND NOT MUCH OF THAT GRADE WAS TO BE SEEN IN THE WORKINGS LATE IN 1918. ALTHOUGH THE DEPOSIT CONTAINED SEVERAL HUNDRED TONS OF MILLING-GRADE ORE, NEAREST CUSTOM MILL WAS AT TOO GREAT A DISTANCE FOR PROFITABLE HAULING.

Comments on the workings information

  • OPEN CUT FROM 10 TO 15 FT. WIDE, 50 FT. LONG AND 40 FT. DEEP, DRIFT 20 FEET LONG INTO FACE OF CUT.
