Project Overview
Three Guardsmen Project | Northwestern British Columbia
A High-Grade Copper-Skarn and Porphyry-Vector Opportunity
Project Overview
GoldHaven Resources’ Three Guardsmen Project is a 100%-owned, 16,234-hectare copper-silver-gold skarn property in the Rainy Hollow area of northwestern British Columbia. The project consists of 14 contiguous mineral tenures in the Atlin Mining Division and is located near Haines Junction, approximately 58 miles north of Haines, Alaska.
Three Guardsmen is strategically positioned in a highly prospective geological setting known for copper-magnetite skarns with associated gold and molybdenum mineralization. The property benefits from strong logistics, with access via a 4-kilometre mining road connecting to paved highway infrastructure and nearby support available through Haines, Alaska.
GoldHaven’s 2025 field program has now confirmed high-grade surface copper mineralization across the property. Results from 126 surface rock samples included 25 samples exceeding 1% copper, with standout assays of 15.85% Cu, 12.75% Cu, and 12.65% Cu. These results validate the project’s historic high-grade copper potential and provide a strong foundation for follow-up geological modelling, geophysics, and drill targeting.
Note: Grab samples are selective by nature and are not necessarily representative of average grades across the property.

A High-Grade Copper System with Scale
Three Guardsmen has a long exploration history dating back to the early 20th century, when copper-bearing magnetite skarns were first documented in 1909. Follow-up work in the 1940s, and drilling in the late 1960s and early 1970s by Taneloy Mines, Imperial Oil, and Eagle River Mines, confirmed significant copper-zinc-silver-gold mineralization but left the broader system underexplored.
GoldHaven’s 2025 program focused on verifying historical high-grade copper samples at the Canadian Verdee and Mildred showings while completing first-pass mapping and assessment across the property. The results successfully validated the historical copper story and confirmed widespread high-grade mineralization at surface.
At Canadian Verdee, high-grade copper occurs in local pods dominated by bornite and chalcocite. These zones grade along strike into broader epidote-dominant skarn with magnetite-chalcopyrite mineralization and widespread malachite staining. Mineralization has been traced over more than 1 kilometre of strike, with geological evidence suggesting the skarn system may continue toward Mildred for a total prospective strike length of approximately 2.6 kilometres.
Len Gal points out additional malachite staining and oxidization between Canadian Verdee and Mildred showings. Suggest of a 2.6 km strike.
GoldHaven collected 126 surface rock samples during the 2025 field program, including grab, chip, and channel samples across key skarn zones. The program confirmed strong copper grades and widespread mineralization across the project including:
126 surface rock samples collected, including 25 samples exceeding 10,000 ppm (1% Cu).
High-grade grab samples including:
J647161 (15.85% Cu)
J647629 (12.75% Cu)
J647753 (12.65 % Cu)
(Note - grab sample grades are not indicative of expected overall grades)
The Three Guardsmen Project hosts high-grade copper mineralization in epidote–magnetite skarns, with extensive malachite-stained pods traced over more than 1 km of strike.
Porphyritic intrusive textures with associated elevated Cu and Mo values have been identified at low elevations in the valley bottom, possibly indicative of an intrusive source for the skarn mineralization.
Geochemical transitions across the property (Cu–Ag → Bi–Te–Au → Mo) suggest a vector towards an intrusive heat source underlying the skarn system.

Geology and Mineralization Potential
The Three Guardsmen Project is underlain by Silurian–Permian sedimentary rocks intruded by Cretaceous diorite bodies — a favourable geological setting for skarn development. The system displays strong mineral zonation, with copper-silver-rich garnet skarns in proximal zones and gold-bismuth-tellurium enrichment in more distal zones.
The 2025 results strengthened GoldHaven’s interpretation of a larger mineralized system. High-grade copper mineralization occurs within epidote-magnetite skarns, with bornite, chalcocite, chalcopyrite, magnetite, and widespread malachite staining. At lower elevations in the valley bottom, porphyritic intrusive textures with elevated copper and molybdenum values suggest a potential intrusive source for the skarn mineralization.
Across the property, geochemical transitions from copper-silver zones into bismuth-tellurium-gold enrichment and molybdenum in altered granites provide vectors toward a possible porphyry intrusion underlying the skarn system. GoldHaven notes that the project lies within a Late Cretaceous tectonic setting that hosts major porphyry systems, including Casino and Red Mountain.
Porphyry Upside Beneath the Skarn System
Three Guardsmen is not just a high-grade copper-skarn story. The 2025 field program identified geological and geochemical evidence that may point toward a deeper or nearby porphyry-style source. Porphyritic intrusive textures, elevated copper and molybdenum values, altered granites, and systematic geochemical zonation all suggest that the exposed skarns may represent the upper or peripheral expression of a larger intrusion-related mineral system.
This porphyry-vector model is central to the next phase of exploration. GoldHaven’s ongoing work is focused on defining potential mineralized intrusive centres through targeted geochemical surveys, structural mapping, and geophysical interpretation.
Path Forward
GoldHaven is advancing Three Guardsmen from high-grade surface confirmation toward systematic target definition.
The next phase of work is expected to focus on:
Integrating 2025 assay results into a district-scale geological model;
Extending mapping across the Canadian Verdee–Mildred trend;
Testing the potential 2.6-kilometre skarn corridor;
Conducting geophysical surveys to refine subsurface targets;
Defining drill targets across high-grade copper-skarn zones;
Evaluating porphyry-source potential beneath or adjacent to the skarn system.
With high-grade copper now confirmed at surface and multiple geological vectors pointing toward a larger mineralized system, Three Guardsmen is positioned as a strong copper-gold exploration asset within GoldHaven’s North American portfolio.

Why Three Guardsmen Matters for Investors & Shareholders
Three Guardsmen gives GoldHaven exposure to a high-grade copper system at a time when copper demand is being driven by electrification, grid expansion, clean energy infrastructure, and strategic supply-chain priorities.
The project combines the features investors look for in an emerging copper exploration story: high-grade surface results, district-scale land position, infrastructure, historical mineralization, skarn continuity, and porphyry-style upside.
The December 2025 assays marked a major milestone. GoldHaven has confirmed copper grades up to 15.85% Cu at surface, with 25 samples above 1% Cu and mineralized skarns traced over more than 1 kilometre of strike. The next step is to convert this high-grade surface footprint into refined geophysical and drill-ready targets.
GoldHaven’s objective is clear: systematically advance Three Guardsmen from surface discovery confirmation toward drill testing of high-grade copper-skarn zones and potential porphyry centres.
