Economic information

Controls for ore emplacement

  • Mineralization Occurs Along Joints Or Slip Planes In Granite. The Ore Zone Ranges From 0.5 To 5 Ft. In Width; The Zone Carries A Streak Of High-Grade Ore That Is 1 To 14 In. Wide. Gold Values Are Associated With The Arsenopyrite. The Ore From Near The Portal Of An Old Drift 15 Ft. Above The Present Drift Was Slightly Radioactive (Huntting, 1956, P. 61).

Comments on the geologic information

  • MINERALIZATION OCCURS IN GRANITE (HUNTTING, 1956, P. 61) AND WOULD APPEAR TO BE IN DIKES EMANATING FROM THE TATOOSH PLUTON (SCHASSE, 1987, P. 29).

Comments on the production information

  • PRODUCED 100 TONS IN 1919; ALSO PRODUCED IN 1925 AND 1928, BUT TOTAL PRODUCTION DOES NOT EXCEED 200 TONS. AN 18-TON SHIPMENT YIELDED 8.05% CU AND 0.09 OZ/TON AU. REPORTED 1% TO 5% CO IN SOME SAMPLES (HUNTTING, 1956, P. 61).
