Two mines on the opposite end of the same vein system that connected underground. The Keeley being the oldest discovered in 1907. The Frontier mine was developed in 1921 and connected to the Keely Mine on the Keeley 6th level in 1962. The mines extend to a depth of 1455ft. They were shut down in 1965. The Woods vein is famous for having the deepest oxidation zone and greatest abundance of secondary enrichment minerals of all the mines in the region.
Total production for the two mines was 19,200,000 oz. of Ag; 3,300,000 lbs. of Co; 27,000 lbs. of Ni; and 10,000 lbs Cu.

NOTE: Great caution must be exercised when collecting in the area because of many unmarked open holes and uncapped shafts.

Benjaminite (TL)
Formula: Ag3Bi7S12
Type Locality:
Description: The mineral was first studied by Shannon (1924), who concluded on the basis of chemical data only that it was a new species and proposed the name benjaminite. Nuffield (1953) re-examined the type specimen and determined that Shannon’s “benjaminite” was actually aikinite. Nuffield, however, noted a minute amount of another phase in the type specimen that deviated from Shannon’s description and analytical data. He described it as a new species retaining Shannon’s name for the mineral. Owing to erroneous data, benjaminite was briefly discredited (1973-1974). The type specimen from TL1 and specimens from two Canadian localities were investigated by Nuffield (1975) and Harris & Chen (1975), and data derived from all three localities were used in a joint proposal to IMA CNMMN for the revalidation of the species.
