Cuddy Mountain
Porphyry
Opportunity – Discovery of a Tier One porphyry copper deposit
Overview: Cuddy Mountain was staked by the Scout team in 2020. The project is located 20 km NW of Cambridge, Idaho, and is hosted within a series of Triassic to Jurassic volcanic and volcaniclastic rocks of the Blue Mountains Province. This region has previously been known to host other magmatic-hydrothermal and volcanogenic massive sulfide deposits in western Idaho and northeastern Oregon.
Historical exploration at Cuddy Mountain has revealed a mineralized porphyry copper occurrence known as the IXL mine. The recent discovery of the Leviathan porphyry copper deposit nearby, made by Hercules Silver Corp. in 2023, has sparked renewed interest in the area. The proximity of the Cuddy Mountain project to the Leviathan deposit suggests a shared geological context and raises the possibility of similar mineralization patterns.
Given these developments, there is a growing belief that the Cuddy Mountain project is part of a larger cluster of Jurassic-aged porphyry copper deposits. This suggests significant potential for further exploration and development in the region, particularly in light of the neighboring discoveries.

Regional Geology
The Cuddy Mountain project is in a geologically significant area straddling the border between British Columbia, Canada, and Idaho, USA. The project lies within the southern extension of the Stikinia/Quesnel terrains, known for their rich deposits of copper and gold, particularly in porphyry formations. This region has historically been of great interest to mining companies due to its mineral wealth, and projects like Cuddy Mountain likely aim to explore and potentially exploit these resources.

Project Geology
The focus of alteration and mineralization at Cuddy Mountain is on a Jurassic-aged pluton, approximately 4 square kilometers, which has intruded Triassic-aged volcanic rocks. This intrusion likely created conditions conducive to mineralization.
The presence of disseminated chalcopyrite-molybdenite, along with potassic alteration, indicates the potential for copper and molybdenum mineralization.
Skarn alteration associated with copper on the northern and southwestern ends of the project indicates that there may be different styles of mineralization present within the area.
These geological characteristics suggest that the Cuddy Mountain project holds potential for both porphyry-style and skarn-style mineralization, particularly copper, with associated molybdenum.

Geochemistry
Historical drill results at Cuddy Mountain, indicating zones of copper mineralization tens to hundreds of meters thick, suggest the presence of significant mineralization within the project area.
Soil sampling conducted in the 1980s revealed that the mineralization extends for over 1 kilometer from the IXL mine, indicating a potentially large mineralized footprint.
Gold was not assayed in the historical drilling, however, the presence of placer gold suggests that there may be gold mineralization associated with the copper deposits. This raises the possibility of additional economic value through gold credits if gold is found to be present in economically significant quantities.

Targets
Concealed bulk-tonnage porphyry copper-gold deposit at the Cuddy Mountain project suggests the presence of a substantial mineral deposit that is not readily visible on the surface.
There is potential to discover high-grade copper skarn mineralization at the Climax and Iron prospects which adds another dimension to the project's prospectivity.

Next Steps
The combination of significant copper mineralization, potential for gold credits, and the extensive footprint of mineralization suggests that the Cuddy Mountain project may have considerable economic upside.
Further exploration and assessment, including detailed geologim mapping, rock chip sampling, geophysical surveys, modern drilling, and assaying techniques, would be necessary to fully evaluate the economic potential of the project.
