The Oregon Mine is a manganese, silver, and gold mine located in Saguache county, Colorado at an elevation of 10,092 feet.
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 (Deposit): OREGON VEIN (ATTITUDE GIVEN ABOVE) OCCUPIES FISSURED ZONE 60 TO 65 FT WIDE, BUT MINERALIZATION CONTAINED IN PARALLEL VEINS UP TO 5 FT WIDE.
Comment (Location): S-T-R, LAT-LONG, AND ELEV. TAKEN FROM BURBANK'S (1932) PLATE 1 (SCALE 1:12000). MINE OR CLAIM LIES NEAR HEAD OF EAGLE GULCH ON WEST SLOPE OF HAYDEN PEAK ; INFO FROM LAND.ST :(1976)
Comment (Development): WORKINGS WERE TOO SHALLOW AND INSUFFICIENT TO CONCLUSIVELY PROVE OUT COMMERCIAL ORE
Comment (Workings): MAIN TUNNEL DRIVEN 560 FT AT N33E. OREGON VEIN AND DRIFT DEVELOPED AT 240 FT INTO TUNNEL WITH 80 FT OF DRIFT TO NW, 240 FT TO SE. NEAR END OF SE BRANCH, SHAFT SUNK FROM SURFACE TO 100 FT BELOW LEVEL.
