Structure: Faults

Alteration: Some Silication

Deposit: Ore occurs As replacements in limestone & granite. The paramount mine (18 claims) was absorbed by the spruce standard co., along with the ada h.m. Co. In 1927-29 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

Deposit type: Polymetallic replacement

Development: Over $100,000 worth of production in early days. In 1926, the paramount consolidated mining co. Shipped several hundred tons of oxidized lead-silver ore and 100 tons of old slag from the mine dump. In 1928, the mine was operated by the sprucemont standard mining co, who reconditioned the mine, and did considerable development work

Geology: Large quartz breccia "blowout" present, porphyry dikes; skarn 500 ft wide x 1/2 mile long

Ore(s): Intrusive Contact, Shear Zone 20 Ft Wide
