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.

Comment (Deposit): IF THE DOUGLAS IS THE SAME AS THE NEWMAN, THERE IS SOME DISCREPANCY, AS THE SAME AUTHOR SAYS THE NEWMAN IS IN THE SE 1/4 ALL REFERENCES SEEM SOMEWHAT CONFUSED IN THE LOCATIONS OF THE MINES AND PROSPECTS IN THIS SECTION
Comment (Production): PRODUCTION REPORTED TO HAVE BEEN ABOUT 3000 TONS PRIOR TO 1888, WHICH SEEMS QUITE LARGE SINCE THESE DEPOSITS WERE NOT DISCOVERED UNTIL 1882 OR LATER; POSSIBLY THIS MINE MAY BE THE SAME AS THE NEWMAN (CEDAR MTN., MENDENHALL)
