Comments on the production information

  • Y-YOD - THE 1914 YEAR OF DISCOVERY FROM UTAH INTERNATIONAL, INC., (1981). OTHER EARLIER SOURCES OF DATA CREDIT 1917 AS THE YEAR OF DISCOVERY. H-HPROD - PRODUCTION TONNAGE AND GRADES ARE FOR THE MILL CITY MINING DISTRICT.

Comments on the reserve resource information

  • OTHER NAME: NEVADA-MASSACHUSETTS. PREVIOUSLY IN ADIT AS: MILL CITY. RESOURCES AS OF 1/83. $50 MILLION WAS INVESTED BY GENERAL ELECTRIC CORP. (GEC), DURING A 12 MONTH PERIOD FROM LATE 1979, TO CONSTRUCT A MINE, GRAVITY MILL, AND APT PLANT AT SPRINGER. PLANNED CAPACITY WAS 725 ST OF WO3 CONC./YR, FOR THE EXCLUSIVE PRODUCTION OF TUNGSTEN WIRE AND CARBIDE POWDER. COMMERCIAL PRODUCTON LASTED ONLY 3 OR 3MONTHS. THE OPERATION SHUT DOWN IN OCT. DUE TO POOR WO3 PRICES. CLOSED SINCE 1982.
