Controls for ore emplacement

  • The Deposit Is In The Silicified-Sericitic Zone Of The Kelsey Porphyry Copper Deposit (Roper, 1973). Mineralization Is In A Shear Zone Striking N10w And Dipping 30-50sw. The Quartz Diorite Is Crumpled Anlong The Shear Zone And Consists Of Light-Green Quartz-Mica And Serpentine Schist Over A Width Of 6-10 Feet. Pinch And Swells Have Formed Along Which Mineralization Has Developed; Mineralization Also Cements Broken Wall Rock And Replaces Schist Along Planes Of Schistosity (Patty, 1921, P. 245).

Comments on the geologic information

  • MINERALIZATION IS IN A SHEAR ZONE IN QUARTZ DIORITE OF JURASSIC-CRETACEOUS (?) SILVER NAIL LAKE PLUTON (FOX, 1970).

Comments on the production information

  • THREE CARLOADS OF ORE WERE SHIPPED PRIOR TO 1911. NINETEEN CARLOADS OF ORE WERE SHIPPED BETWEEN 1917 AND 1921; THIS ORE AVERAGED 7% CU, 6 OZ/TON AG, AND $2/TON AU. APPROXIMATELY 1000-2000 TONS OF 1-2% CU ORE REMAINS ON THE DUMP AND IN THE WORKINGS (PATTY, 1921, P. 244).
