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.

Comments
Comment (Production): THE MALAKOFF FORMERLY OPERATED BY NO. BLOOMFIELD MINING CO. PRODUCED $2,830,000 1870 TO FEB. 1884; A DRAGLINE DREDGE WAS OPERATED AT THE MALAKOFF FROM 10/16 TO 12/31, 1941 AND YIELD FROM 72,000 CU.YDS. OF GRAVEL WAS 333 OZ. GOLD, 33 OZ. SILVER; IN 1942, YIELD FROM 146,000 CU.YDS. WAS 694 OZ. GOLD AND 64 OZ. SILVER.
Comment (Workings): HYDRAULICKING IN THE PAST; OWNERS WERE CONSIDERING INSTALLATION OF MECHANICAL METHODS IN 1945.
Comment (Deposit): SAN JUAN GOLD CO. HAS HOLDINGS OF 5,484 ACRES OF PATENTED MINING CLAIMS, INCLUDING THE MALAKOFF, CENTRAL, CONSOLIDATED, AND WESTERN PLACER MINES (AND OTHERS?). SAMPLING OF THE CHANNEL INDICATES A GOLD CONTENT CONSIDERABLY HIGHER THAN THAT FORMERLY RECOVERED, FOR 100 MILLION CU. YDS. DOWN THE CENTER.
