All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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 (Deposit): IN RECENT YEARS THE AREA HAS BEEN HEAVILY EXPLORED FOR CARLIN-TYPE GOLD IN THE LOWER PLATE ROCKS, AND FOR BARITE IN UPPER PLATE WESTERN ASEMBLAGE ROCKS. DEVELOPEMENT OF THE PROPERTY CONSISTS OF 4 SHORT ADITS AND SCATTERED SURFACE WORKINGS. PRODUCTION HAS BEEN ABOUT 350 TONS ; INFO.SRC : 1 PUB LIT

Comment (Workings): 4 SHORT ADITS, SCATTERED SURFACE WORKINGS

Comment (Location): UTM PRECISION 1000 M

Comment (Development): AREA HAS RECENTLY BEEN HEAVILY EXPLORED FOR CARLIN-TYPE GOLD DEPOSITS IN LOWER PLATE ROCKS; BARITE IN UPPER PLATE ROCKS.

Comment (Geology): THE ORE DEPOSITS ARE MAINLY LEAD AND ZINC MINERALS THAT REPLACE LIMESTONE & DOLOMITE ALONG FAULTS AND BEDDING PLANES ADJACENT TO BASALTIC DIKES

Comment (Deposit): LEAD-ADN ZINC MINERALS REPLACE LIMESTONE AND DOLOMITE ALONG FAULTS AND BEDDING PLANES ADJACENT TO BASALTIC DIKES.
