Comments on development

  • THE PROPERTY WAS WORKED ON A SMALL SCALE IN 1942 - 1943 BY THE CHATHAM MILLING CO. AND 260 TONS WERE SHIPPED TO C. C. DAUGHTERY' S MILL AT TROY. IN 1943, 33 TONS OF ORE WAS SHIPPED TO THE U. S. METALS REFINING CO. IN 1942 - 43 (?) TWO 200 TO 250 FOOT CORE HOLES WERE DRILLED. ANALYSIS SHOWED LESS THAN 3% CU. IN 1944 ELEVEN CORE HOLES TOTALING 1695 FEET WERE DRILLED BUT DID NOT SHOW APPRECIABLE QUANTITIES OF ORE.
