Tombstone Gold Belt Overview
The Tombstone Gold Belt is part of the Tintina Gold Province that extends through more than 1000 km of the northern North American Cordillera that includes Alaska, Yukon and the Northwest Territories.
In Yukon and Alaska, the belt is host to a number of large Reduced Intrusion-Related Gold System (RIRGS) deposits. These gold systems are characterized by sheeted, auriferous quartz veins forming in the carapace zones of reduced felsic plutons. They have a characteristic geochemical signature containing Au-Bi-Te-As-W metal assemblage within and surrounding the intrusion and a characteristic geophysical signature of a magnetic low (ie. reduced) and conductivity low centered on the intrusion. These occurrences can form large, truly world class deposits. Currently, the Fort Knox mine in Alaska and the Eagle mine in Yukon are producing from RIRGS deposits and historically, the Brewery Creek mine in Yukon was a RIRGS producer.
A recent major discovery by Snowline Gold Corp at their Valley occurrence in the Rogue Plutonic Complex in the Selwyn Basin of Yukon, indicates these deposits can be discrete, yet significant gold occurrences.
Rackla Metals is targeting RIRGS mineralization on the southeastern part of the Belt in eastern Yukon and western Northwest Territories. The company presently owns a portfolio of over 59,000 hectares of multiple high quality exploration targets, within the highly prospective Tombstone Gold Belt.
RIRGS deposits occur in clusters. In western Yukon, the western cluster consisting of the Eagle, Aurmac, Brewery Creek, RC Gold, Florin and Raven deposits contains +20 million ounces of gold1. The eastern cluster being explored by Snowline Gold at their Rogue Plutonic Complex and Rackla at the Astro Plutonic Complex is rapidly developing and may offer similar potential.
The Astro Plutonic Complex is comprised of four Cretaceous-aged intrusions. The western most Keele Pluton belongs to the Mayo Suite, the northern Canol Trail Stock belongs to the Tungsten Suite, the eastern most Border Pluton and southern most Kelvin Stock are both Tombstone Suite.
Rackla is continuing to build on this significant land package through staking and strategic acquisitions. Our management team has substantial experience in this belt and has compiled a large historic geochemical and geophysical database to provide a roadmap for discovery.
