Comments

Comment (Production): THE VEIN WAS DISCOVERED IN 1887. IN 1889 A SHIPMENT OF HIGH-GRADE SILVER ORE WAS SENT TO THE SMELTER IN HELENA, MONTANA. A 200-FT SHAFT WAS SUNK ON THE VEIN, AND AN AVERAGE OF 10 TONS OF HIGH-GRADE ORE PER MONTH WAS SHIPPED TO SMELTERS. SILVER ORE WAS SHIPPED TO A CONCENTRATING MILL IN RUBY CITY UNTIL MID-1893 WHEN THE MINE WAS FORCED TO SHUT DOWN BECAUSE OF THE SILVER PANIC. TOTAL PRODUCTION TO THIS TIME AMOUNTED TO $36,000. FROM 1958 TO 1964 HAND-SORTED SHIPMENT WERE SENT TO THE SMELTER IN TRAIL, BRITISH COLUMBIA. EXCEPT FOR A SMALL SHIPMENT IN 1967, THOSE WERE THE LAST SHIPMENTS FROM THE MINE (MOEN, 1973).

Comment (Geology): THE VEIN IS IN BIOTITE GNEISS OF THE PRE-JURASSIC SALMON CREEK SCHIST AND GNEISS PARALLEL TO AND WEST OF THE CONTACT WITH GRANODIORITE GNEISS (MOEN, 1973).

Comment (Deposit): THE UNDERGROUND WORKINGS AT THE MINE CONSIST OF A DOUBLE-COMPARTMENT 500-FT SHAFT AND A SINGLE-COMPARTMENT 200-FT SHAFT. SEVERAL LEVELS HAVE BEEN DRIVEN AND MINED (MOEAN, 1973). ; INFO.SRC : 1 PUB LIT
