Comments

Comment (Location): LOCATED NEAR THE HEAD OF LITTLE COPPER CREEK.

Comment (Development): .5 TONS OF ORE WAS SHIPPED IN 1952 BUT SUCH AN AMOUNT DOES NOT MAKE THIS A PRODUCING MINE. PROPERTY CONSISTS OF 5 UNPATENTED CLAIMS

Comment (Deposit): THE DEPOSIT GENERALLY CONFORMS TO BEDDING AND IS EITHER SELECTION REPLACEMENT OR MINERALIZATION ALONG BEDDING PLANE SLIP.

Comment (Workings): ONLY ONE SHALLOW PIT COMPRISED THE WORKINGS IN 1952.
