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.
