Cuddy Mountain - Cu Porphyry
Opportunity – Discovery of a Tier One porphyry copper deposit
Cuddy Mountain was staked by the Scout team in 2020. Located 20 km NW of Cambridge, Idaho, the property is hosted within a series of Triassic to Jurassic volcanic and volcaniclastic rocks of the Blue Mountains Province. The property lies within the southern extension of the porphyry Cu-Au Stikinia/Quesnel terrains of British Columbia into Idaho.
Historical exploration at Cuddy Mountain centered around a mineralized porphyry copper occurrence known as the IXL mine. Hercules Silver Corp.’s 2023 discovery of the Leviathan porphyry copper deposit has sparked renewed interest in the area, as the Hercules ground is immediately adjacent to Scout’s Cuddy Mountain property. Structural interpretations suggest that Cuddy Mountain represents an untested and shallow extension of the Leviathan porphyry.
Highlights:
Extension of the well-endowed Porphyry Cu-Au Stikinia/Quesnel terrains of British Columbia into Idaho
Significant land position; >10 km2 of Jurassic porphyry Cu alteration/mineralization with skarn mineralization, adjacent to 2023 Hercules porphyry Cu discovery
High-potential drill targets; multi-km undrilled porphyry Cu, Mo, and Au surface anomalies validated by 2024 geophysics – three interpreted porphyry centers
Shallow, 10s - 100s meter thick intercepts of 0.1-0.8% Cu in historic drilling support the presence of a large porphyry Cu system – no historic Au assays despite prior placer Au production on the property
The size of the geochemical anomaly footprint is on par with world-class porphyry deposits like Bingham Canyon (Utah) and El Teniente (Chile)
Scout is positioned to drill test these anomalies in 2025-2026 with a 10,000 m Phase I drill program
Project Geology:
Host Rocks: Alteration and mineralization are centered on a ~4 km2 Jurassic-aged plutonic stock. This stock intrudes Triassic-aged volcanic/sedimentary pile analogous to the Stikinia/Quesnel Terranes of British Columbia.
Structure: Regional-scale thrust faulting and folding associated with accretion has rotated the porphyry system to the northwest. Small- to modest-offset normal faults on the property related to Basin and Range extension post date thrust faults/folding.
Mineralization:
Porphyry Cu-Mo: Disseminated chalcopyrite-molybdenite mineralization is associated with potassic alteration (IXL Mine). Shallow historic drilling identified 10s-100s-meter thick zones of Cu mineralization.
Cu Skarn: Chalcopyrite-magnetite-specular hematite mineralization associated with skarn-type alteration (Climax prospect). Outcropping Cu Mineralization in garnet-magnetite skarns (Railroad prospect).
Gold Potential: Historic Au placer production on the property suggests an untested Au-bearing porphyry system.
2024 Work:
Soil and Rock Sampling: In 2024, Scout collected 1100+ soil and rock samples which indicate robust Cu-Mo mineralization concentrated around three inferred porphyry centers
Geophysics: Scout’s 2024 VLF, 3DIP, and Magnetics surveys validated findings of the soil survey and outlined near-surface porphyry and skarn targets.
