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.

Comments
Comment (Deposit): Discovery Year: EARLY 1880'S
Comment (Location): DEPOSIT ON UNSURVEYED TERRITORY, SECTION NUMBERS ESTIMATED UTM COORDINATES OF SHAFT.
Comment (Commodity): HIGH GRADE ORE GENERALLY FOUND AS NARROW STRINGERS WITHIN VEIN
Comment (Reserve-Resource): SCHAFER STATES THAT WHILE DEVELOPED PORTION ESSENTIALLY MINED OUT, IT IS PROBABLE THAT ORE EXISTS TO A CONSIDERABLE DEPTH BELOW THE PRESENT WORKINGS. ASSUMING THAT THE MINE IS DEVELOPED TO THE 500 LEVEL AND ASSUMING THAT THE VEIN CONTINUES DOWNWARD FOR AN ADDITIONAL 250 FT. WITH A WIDTH OF 3 FEET GIVES THE RESOURCE ESTIMATE. ORE PRODUCED APPEARS TO HAVE BEEN HIGH GRADE BUT THE PAY WIDTH WAS PROBABLY ABOUT 1 FT SO THE LOW GRADE SHOWN IS DUE TO DILUTION FOR A 3 FT WIDE STOPE
Comment (Production): EARLY PRODUCTION RECORDS VAGUE. PRODUCTION FROM 1918-1923 HAD REPORTED VALUE OF $1,500,000 MOSTLY IN SILVER.
Comment (Workings): DEPOSIT DEVELOPED BY 550 FT. SHAFT WITH LEVELS AT 100 FT. INTERVALS AND 2 ADITS, THE MOULTON TUNNEL & THE BLACKSMITH TUNNEL. MINE STATUS CURRENTLY REPORTED AS DEVELOPING.
Comment (Geology): PRECAMBRIAN CRYSTALLINE ROCKS ARE PRE-BELT.

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.
