Comments on the production information

  • PRODUCTION FROM COEUR D'ALENE, EUREKA & ELLIS, INTERSTATE, AND STIBNITE HILL MINES IN 1941. IN 1942, COUER D'ALENE DID NOT PRODUCE. THE OTHER THREE DID, AS WELL AS AN UNNAMEDMINE. STIBNITE HILL MINE PRODUCED IN 1951 AND 1953. MINOR PRODUCTION IN EARLY 1900'S. CURRENTLY PRODUCING.

Workings at the site

  • Type of workings Underground
    Length 182.88M

Comments on the workings information

  • IN THE PAST, NUMEROUS ADITS AND PROSPECT PITS HAVE BEEN OPENED ALONG THE ANTIMONY VEINS. IN 1960 ONLY 2 ADITS, THE BARTO AND THE BABBIT WERE ACCESSIBLE: THE BARTO WAS ACCESSIBLE FOR 340 FT; THE BABBIT WAS OPEN FOR ITS ENTIRE LENGTH OF 260 FT. 1973 PUBLICATION STATES THAT A MODIFIED ROOM AND PILLAR METHOD IS USED IN MINE. WHILE VEINS GENERALLY DIP LESS THAN 30 DEG, MINING IS COMPLICATED BY HIGH ANGLE FAULTS.

Comments on development

  • PROPERTY WAS IDLE FROM MID 1900'S TO WW II. DURING WW II OWNERSHIP WAS DIVIDED AMONG SEVERAL GROUPS. KNUTE KIRKEBERG CONSOLIDATED OWNERSHIP OF PROPERTIES BETWEEN 1964 AND 1968 . IN 1969 PROPERTY WAS SOLD TO US ANTIMONY CORP. ; ECON.COM: 350 TON/DAY MILL WITH REFINERY

Subject category Comment text
Deposit MOST VEINS STRIKE NE AND DIP AT LOW ANGLES TO THE NW. VEINS RANGE IN WIDTH FROM 5 FT TO LESS THAN 1 IN AND METALLIC CONTENT ALSO DIFFERS CONSIDERABLY ALONG THE VEIN. IN PART, THE VEINS APPEAR TO BE BEDDING PLANE VEINS, BUT SOME ARE CROSSCUTTING. STIBNITE MOST OFTEN OCCURS AS NARROW 1 - 6 IN VEINS OR ELONGATED LENSES THROUGHOUT THE OVERALL VEIN STRUCTURE.
Deposit BATTERY GRADE SB PRODUCED IN FURNACE - 95 - 96% SB; SODIUM ANTIMONATE, ALSO PRODUCED BY FIRST LEACHING CONCENTRATE - USED IN GLASS INDUSTRY. FUTURE PLANS TO FUME SB TO SB203 REPORTED BY J. LAWRENCE, PRESIDENT, U.S. ANTIMONY. ; INFO.SRC : 1 PUB LIT
