Project Overview
Magno Project | Cassiar, British Columbia
A District-Scale Polymetallic and Critical Mineral Opportunity
Magno is underlain by Proterozoic–Paleozoic carbonate and clastic rocks of the Cassiar Terrane intruded by the Cassiar Batholith — a geological environment capable of hosting multiple deposit types. Exploration has already confirmed the presence of:
Carbonate Replacement Deposits (CRDs): High-grade silver-lead-zinc systems in Magno North, enriched with tin, indium, and gold.
Porphyry Systems: Copper-molybdenum targets associated with the Cassiar Batholith in Magno West.
Skarn and Vein Systems: Occurring throughout the property and prospective for polymetallic mineralization.
Importantly, Magno exhibits unusually high indium grades and anomalous gallium values, both classified as critical minerals with growing strategic demand. These elements provide valuable exploration vectors linking shallow CRD and skarn mineralization to deeper porphyry systems, suggesting strong potential for scale at depth.
Tungsten
A Strategic Acquisition
In June 2025, GoldHaven expanded the Magno Project through the acquisition of the Kuhn and Dead Goat claims, which include a historical resource estimate at Kuhn North of 409,300 tonnes grading 0.48% WO₃ and 0.134% MoS₂ (not NI 43-101 compliant). The Kuhn claims host a well-developed skarn system historically drilled by Shell Canada, confirming the presence of scheelite (tungsten) and molybdenite.
Tungsten’s unmatched properties — the highest melting point of any metal, extreme hardness, and resistance to wear — make it indispensable for aerospace, defense, advanced manufacturing, and nuclear energy. Yet more than 80% of the world’s tungsten supply is controlled by China, which in 2025 introduced new export restrictions that effectively halted shipments. This supply shock has sharply increased prices and underscored the urgent need for secure, Western-based sources of this critical mineral.
Magno’s tungsten-rich skarns position GoldHaven as a potential key player in diversifying the supply chain for one of the most strategically important metals in North America.
Exploration History and Current Work
The Magno property has been known since the early 1950s, with systematic exploration ramping up in the 1970s and 1980s. Historical work included prospecting, trenching, soil and rock geochemistry, geophysical surveys, underground development, and drilling. These efforts confirmed multiple zones of polymetallic mineralization, including silver, lead, zinc, copper, and associated critical metals such as indium, tin, and gallium. Despite this history, large portions of the property remain underexplored.
In 2025, GoldHaven advanced the project with a series of modern exploration programs:
Summer Field Programs: Mapping, channel sampling, and soil geochemistry confirmed mineralization across Magno North and West, with strong silver-lead-zinc and copper-molybdenum signatures accompanied by critical metals.
Critical Mineral Vectoring: Elevated indium/zinc ratios were recognized as key exploration guides to deeper porphyry systems.
Kuhn and Dead Goat Integration: Newly acquired tungsten-rich ground was mapped and incorporated into the district geological model.
These programs validated and expanded the historic dataset, providing GoldHaven with a clearer geological model and prioritized targets for follow-up exploration.
*These estimates are historical in nature and do not meet NI-43.101 standards and therefore should not be relied upon.
Looking ahead, GoldHaven’s strategy is to focus exploration in three directions:
Advancing high-grade CRD targets in Magno North.
Testing porphyry copper-molybdenum systems in Magno West.
Further delineating and expanding tungsten mineralization in the Kuhn area.
The company is currently evaluating geophysical options to refine these targets ahead of a potential maiden drill program. Assay results from the 2025 field season, ongoing district-scale geological modeling, and drill planning are expected to serve as near-term catalysts.
Why Magno Matters for Investors
Magno is more than a traditional polymetallic project. It provides diversified exposure to both precious metals (silver and gold) and a suite of strategic critical minerals (tungsten, indium, gallium, zinc, and tin) — commodities increasingly central to clean energy, advanced manufacturing, and defense supply chains.
The project’s location in one of British Columbia’s premier mining jurisdictions, bordered by active exploration companies Cassiar Gold and Coeur Mining, further underscores its strategic positioning. Combined with scale, infrastructure, and a broad commodity mix, Magno aligns directly with global trends in supply security and industrial transition.
For GoldHaven shareholders, Magno represents not only a polymetallic exploration opportunity, but also a chance to participate in securing the metals that will underpin technological progress, industrial competitiveness, and national security in the decades ahead.
* Historical Estimate Disclosure: This resource estimate constitutes a “historical estimate”, as that term is defined in National Instrument 43-101 Disclosure Standards for Mineral Projects (“NI 43-101”). This information is derived from summary report McDame project 82-546-10512, filed by Shell Canada Resources. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and accordingly the estimates may not be relevant or reliable.] The Company is not treating the historical estimate as current. In order to verify the historical estimate, a qualified person needs to review the historical data, review any work completed at the projects since the date of the historical estimate and complete a new mineral resource estimate
