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 (Commodity): OLD REPORT OF STIBNITE IS PROBABLY INCORRECT. STIBNITE NOT FOUND IN LATER INVESTIGATIONS.

Comment (Development): CLAIMS STAKED BY JOE KONECHNEY IN 1920, WHO PROCEDED TO EXCAVATE SINGLE HANDEDLY, BY HAND, 900 FT. OF UNDERGROUND WORKINGS (BELIEVE IT OR NOT!) AS WELL AS PITS AND TRENCHES. ADIT PARTIALLY FLOODED IN 1943. NO PRODUCTION.

Comment (Location): USBM OFR 9-85, FIG. 5, MAP LOC. 64; USGS MF-444, LOC. 5 LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): QUARTZ VEINS AND THIN LAYERS OF BRECCIA AND GOUGE IN QUARTZ MONZONITE IN ZONE 200 FT. WIDE TRACED FOR 1,000 FT.. CONTAINS ARSENOPYRITE, CHALCOPYRITE, GALENA, HEMATITE, METAZEUNERITE, PYRITE, PYRRHOTITE, SCHEELITE, MAGNETITE, ILMENITE, AUZERITE, CHRYSOCOLLA.

Comment (Workings): TWO ADITS WITH TOTAL OF 900 FT. OF UNDERGROUND WORKINGS. MAIN ADIT 800 FT. DEEP. PORTAL OF UPPER ADIT CAVED, LOWER ADIT ICED SHUT. SEVERAL SURFACE PITS AND TRENCHES NOW SLUMPED IN. MAIN ADIT WENT THROUGH ORE VEIN, ALTHOUGH KONECHNEY DID NOT REALIZE IT AND KEPT DIGGING.

Comment (Geology): TERTIARY QUARTZ MONZONITE PLUTON INTRUDES CRETACEOUS SEDIMENTARY ROCKS OF KUSKOKWIM GROUP.

Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
