Through a partnership with USA’s largest private landholder, Aguila has accessed mineral rights to a large privately owned tract of forestry land in the Western Cascade Ranges of Oregon. This area, called the WUSA Gold Project, secures a district that is highly prospective for high and low sulphidation epithermal gold systems. The site lies immediately east and south of the township of Cottage Grove adjacent to the Bohemia mining district where a 19th century gold rush occurred, and placer gold mining is still active.
For more than 150 years, as the gold price moved from $35 to $1900 per ounce, the gates to WUSA remained locked to miners such that almost no exploration was completed. Through long term relationship building, demonstrated commitment best practice ESG and exploration methods, the project is now accessible to Aguila. The Company has a unique opportunity to explore a large tract of land with multiple evidence for epithermal gold mineralization including two gold in drilling discoveries.
The Cascade Range in Oregon is underlain by Eocene to Holocene intermediate to felsic volcanic and volcaniclastics rocks erupted along the western margin of North America. The Western Cascades were formed by same subduction/ Cordilleran tectonics that created gold-rich mineralization in the Andes of Peru, Chile and Columbia, and the Tethyan Belt of Serbia, Turkey and Romania.
The Oligocene-Miocence arc volcanics/volcaniclastics and intrusives are highly prospective for intrusion related high and low sulphidation epithermal gold systems that are well known around the Pacific Rim of Fire. In these volcanics near the WUSA Gold Project, there are numerous sites that provide evidence for intense epithermal alteration and intrusion-associated mineralization:
Aguila has developed a clear exploration model for discovery that can be quickly and cheaply applied at WUSA. Two stand out prospects Walker Creek (WC) and Scorpion-Cinnabar (SC) with gold in drilling have been identified. Regional potential is exceptional.
Epithermal gold deposits have a reasonably predictable set of features that relate to their formation at shallow depths of up to 1.5 km below the surface of the earth in continental margin settings. Around the Pacific Rim, these deposits contribute over 1 million oz per year in production. Low sulphidation veins and breccia bodies with subtle surface footprints form high-grade targets for underground mining. Vein widths are variable however grade can range to ounces per tonne, and near misses may be subtle. High-grade, low-tonnage deposits can develop over large lateral extents.
