Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Geology): QUARTZ AND STIBNITE ARE THE MOST ABUNDANT VEIN MINERALS.
Comment (Workings): 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.
Comment (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
Comment (Production): 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.
Comment (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
Comment (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.

Principal Gold Districts of Montana
In Montana, 54 mining districts have each have produced more than 10,000 ounces of gold. The largest producers are Butte, Helena, Marysville, and Virginia City, each having produced more than one million ounces. Twenty seven other districts are each credited with between 100,000 and one million ounces of gold production. Read more: Principal Gold Districts of Montana.
