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): 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.
