About the MRDS Data:
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.

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 (Location): USGS B 1525, FIG. 53, 54, 55. LOCATION IS AT ENTRANCE TO SUMDUM CHIEF VEIN STOPE LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): BALD EAGLE MINING CO. FORMED IN 1893, PRODUCTION STARTED IN 1894, CONTINUED UNTIL 1903. SUMDUM MINING CO. FORMED IN 1899. MINE CLOSED IN 1903 AFTER ORE BODY MINED OUT.
Comment (Deposit): TWO QUARTZ VEINS IN FISSILE GRAPHITIC LIMESTONE. SUMDUM CHIEF VEIN STRIKES N 80 DEGREES E AND DIPS 84 DEGREES N; AND IS 3 FT. WIDE AT SURFACE BUT NARROWS TO VEIN FILLING WHERE INTERSECTED BY DRIFT AT 1,200 FT.. BALD EAGLE VEIN IS 2 FT. WIDE AT SURFACE AND WIDENS TO 20 FT. WHERE INTERSECTED BY DRIFT AT 500 FT.. AT THAT DEPTH ORE GRADE IS ONLY 0.05-0.10 OZ/TON AU, WHICH WAS TOO UNECONOMICAL TO MINE. VEINS CONTAIN MINOR PYRITE, SPHALERITE, GALENA, CHALCOPYRITE, AND GOLD IN DISSEMINATED FINE GRAINS. GOLD APPEARS TO HAVE BEEN INTRODUCED WITH QUARTZ AND OTHER SULFIDES, AND IS INTERGRANULAR WITH QUARTZ, OFTEN FORMING ADJACENT TO SULFIDES.
Comment (Workings): 3,500 FT. HAULAGE DRIFT WITH 1,600 FT. RAISE DRIVEN FROM END OF DRIFT. AERIAL TRAM CONNECTS MAIN PORTAL WITH MILL, AND 1 MI. OF ROAD AND SURFACE TRAMWAY. ALL ARE NEARLY OBLITERATED, AND MAIN PORTAL OF MINE IS CAVED (AS OF 1984).
