Margaux Resources’ Kootenay Arc project is comprised of the Jersey-Emerald, Sheep Creek, Bayonne, Jackpot, Ore Hill and Aspen properties, which together encompass approximately 19,000 hectares. The southern boundary of the project coincides with the Canada-USA border, with claims extending to the north for about 30 km.
In a regional sense, the project straddles the deformation zone at the boundary between the accreted Quesnel terrane and sediments that were deposited off the western margin of ancestral North America. That deformation zone is locally referred to as the Kootenay Arc and is well known for the abundance of lead-zinc mineralization. Numerous historic mines are located in the belt, including the Jersey-Emerald mines on Margaux’s property. The area hosts a diversity of mineralization, including tungsten skarn, gold skarn, and orogenic gold, in addition to the Kootenay Arc lead-zinc deposits.
A deep-seated transverse Archean basement structure, the Vulcan structure, trends northeast through Margaux’s project area. Intermittent reactivation of this structure has influenced emplacement of intrusives as well as mineralization. It accounts for the diversity in terms of commodity, style and age of mineralization in the area, as well as explaining the increased concentration of deposits in the southern portion of the Kootenay Arc.
