Comment (Location): W FLANK OF RANGE WNW OF ADA H MINE
Comment (Production): OVER $100,000 WORTH OF ORE WAS PRODUCED IN THE EARLY DAYS
Comment (Deposit): THE SPRUCE STANDARD MINE IS DEVELOPED BY AN INCLINE SHAFT 265 FT DEEP WITH 2 LEVELS WITH OVER 2000 FT OF WORKINGS. EARLY DAY PRODUCTION IS CREDITED AT OVER $100,000 IN LEAD-SILVER-COPPER ORE; IN 1926 THE PARAMOUNT CONSOLIDATED MINING CO. SHIPPED SEVERAL HUNDRED TONS OF OXIDIZED LEAD-SILVER ORE AND 100 TONS OF OLD SLAY FROM THE MINE DUMP; IN 1928 THE MINE WAS OPERATED BY THE SPRUCEMONT STANDARD MINING CO. WHICH RECONDITIONED THE MINE, AND DID CONSIDERABLE DEVELOPMENT WORK. THE MAIN LODE RANGES UP TO 5 FT OR 6 FT IN WIDTH. THE ORE OCCURS IN REPLACEMENT DEPOSITS IN LIMESTONE AND GRANITE PORPHYRY. THE PARAMOUNT MINE OF 18 CLAIMS WAS ABSORBED BY THE SPRUCE STANDARD CO., ALONG WITH THE ADA H.M. CO. IN 1927-28. ; INFO.SRC : 1 PUB LIT
