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.
Mine Description
Location: Altitude, about 8,685 ft; 800 ft S. 28° W. of new shaft of Conger mine.
Workings: Mine originally continuous with old Conger workings; largely stoped out and inaccessible for many years.
Geology: On southern part of Conger vein and exploited part of main Conger ore shoot.
History and production: Work on part of Conger vein on Oregon claim begun at least as early as 1903 or 1904; resulting large output led to further development of main Conger mine, where work had been stopped at depth of 80 ft. Output from Oregon up to 1907 not known but fairly large. From 1907 to 1919 and from 1923 to 1929 mine produced about 5,000 units of WO3 in ore averaging 14.51 percent WO3. According to Hershey, production to 1914 estimated at about $50,000, equivalent to about 10,000 units of WO3. Mine owned by Wolf Tongue Mining CO.
