Project Overview
Three Guardsmen Project | Northwestern British Columbia
A High-Grade Copper-Skarn and Gold-Skarn Opportunity
Geology and Mineralization Potential
The property is underlain by Silurian–Permian sedimentary rocks intruded by Cretaceous diorite bodies, a favorable setting for skarn development. Skarn systems at Three Guardsmen show strong zonation:
Copper and silver-rich garnet skarns in proximal zones.
Gold, bismuth, and tellurium-enriched distal zones, characteristic of productive gold-skarn environments like Hedley, BC.
Recent fieldwork in 2025 identified high-grade copper mineralization in epidote- and magnetite-rich skarns with extensive malachite staining across more than a 1 km strike length. Geochemical pathfinders and alteration textures suggest a nearby intrusive source — raising the potential for an undiscovered porphyry system feeding the skarns.
Three Guardsmen has a long history of exploration dating back to the early 20th century. Copper-bearing magnetite skarns were first documented in 1909, with follow-up evaluations in the 1940s and subsequent drilling in the late 1960s and early 1970s by Taneloy Mines, Imperial Oil, and Eagle River Mines. Though early programs confirmed significant mineralization, low commodity prices prevented development.
In the 1980s, renewed exploration led to additional sampling and staking of new claims, laying the groundwork for modern programs. Skarn samples from historical trenching consistently returned multi-percent copper and zinc values, along with strong silver and gold assays.
2025 Exploration Program
Assay results from these samples are pending and expected to serve as near-term catalysts, guiding the next phase of geological modeling and drill targeting.
Mineral system analogues to world-class porphyry-skarn districts, including Casino and Red Mountain.
Alteration patterns and geochemical vectors consistent with a proximal intrusive source.
Copper-silver-rich skarns extending over >1 km strike.
GoldHaven’s technical team completed its summer 2025 exploration program at Three Guardsmen, collecting 126 rock samples (grab, chip, and channel) across key skarn zones. Field observations revealed high-grade copper pods dominated by chalcocite and bornite, with secondary chalcopyrite and widespread malachite staining.
The exploration program confirmed:
Path Forward
Building on the successful 2025 program, GoldHaven is preparing to:
Integrate assay results into a district-scale geological model.
Conduct geophysical surveys to refine target definition.
Advance toward strategic drill testing of high-grade skarn zones and potential porphyry centers.
With its combination of historic high-grade results, new evidence of large-scale mineralization, and excellent infrastructure access, Three Guardsmen is emerging as a highly compelling copper-gold exploration play in a proven mining jurisdiction.
