Mine Info

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 (Geology): UPPER LIMIT OF VEIN SYSTEM IS THE GALLATIN DEVELOPMENT HAS BEEN HAMPERED AT DEPTH BY WATER BUT UNDERLYING GROS VENTRE FM. SOURCE OF SPECULATION AS TO ORE CONTENT.

Comment (Workings): DEPOSIT DEVELOPED BY SEVERAL SHAFTS, ADITS AND OPEN CUTS - FOR A LENGTH OF ABOUT 850 M AND A VERTICAL RANGE OF 76 M. WORKINGS BETWEEN THE IRMA & REPUBLIC MINES ARE GROUPED BUT NOT INTERCONNECTED.

Comment (Reserve-Resource): NO ESTIMATE MAY BE MADE BECAUSE OF SPARSE DATA AND GEOLOGIC COMPLEXITY. HIGH GRADE OF ORE PRODUCED INDICATES THAT SIGNIFICANT AMOUNTS OF LOW-GRADE ROCK MAY BE PRESENT AND DISCOVERY OF HIGH GRADE SHOOTS AT DEPTH IN THE GROS VENTRE FM. IS PROBABLE.

Comment (Production): GREATEST PRODUCTION ABOUT 1906-7, 1920-24, 1936-49. SOME ORE MAY HAVE BEEN SHIPPED AFTER 1949. PRODUCTION RECORDS ARE SPARSE AND AMBIGUOUS.

Comment (Deposit): Discovery Year: 1870'S

Comment (Deposit): THE REPUBLIC VEIN WAS THE FIRST VEIN TO BE DISCOVERED IN THE DISTRICT
