Platinum Group Metal Projects
Montgomery Mine
The Montgomery Mine claim group consists of 25 unpatented lode claims covering 500 acres of BLM land near Copeland in Boundary County, ID. The claims are located on the southwest slope of Hall Mountain with approximately 1800’ of relief in the claim group.
The area is underlain by the Prichard and Allrich formations of the lower Belt series. The quartzites and impure quartzites of the Prichard and Allrich formations have been locally intruded by diorite sills. These sills strike northwest across the property and dip gently to the northeast.
The Diorite sills exhibit anomalous Platinum Group Metals (PGM) values that may have economic potential. The sills also host prominent quartz veins that exhibit significant Copper, Lead, Silver, and Gold values that provide an additional economic potential to the property.
Exploration History
The property has been explored by approximately 3500 ft of drift development in 3 primary tunnels and 4 smaller tunnels. This development appears to establish lateral continuity of the sills and veins. In addition to drifting there have been several diamond drill holes completed and at least one surface geophysics survey has been run on the property.
Stillwater Extension Claims
The Stillwater Extension property consists of 10 unpatented lode claims covering 200 acres of the Stillwater Complex of south central Montana. The Stillwater Complex is a mafic-ultramafic layered intrusive that includes the 28-mile long J-M Reef. The uniquely PGM-enriched J-M Reef and its characteristic host rock package represent one such layer in the sequence. The PGMs in the J-M Reef consist primarily of palladium, platinum and a minor amount of rhodium. The reef also contains approximately 3 percent iron, copper and nickel sulfides, and trace amounts of gold and silver.
Exploration History
The Johns Manville Corporation discovered palladium and platinum along the J-M Reef of the Stillwater Complex in the early 1970s. In 1979 a Manville subsidiary partnered with Chevron to develop the property. Underground operations at the Stillwater Mine commenced in 1986.
