Vancouver, British Columbia, August 27th, 2026 – GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) (“GoldHaven” or the “Company”) is pleased to announce that drilling has commenced at its 100%-owned Magno Project in northwestern British Columbia. The first drill hole of the 2026 program is being initiated today at the Kuhn tungsten target, marking the beginning of the Company’s maiden drill campaign at Magno.
The program represents an important transition for GoldHaven from surface exploration and target development to drill testing across a large polymetallic system prospective for tungsten, silver, lead, zinc, copper and other critical and strategic metals.
Highlights
Drilling commenced at Kuhn: GoldHaven’s first-ever drill hole at Magno is being initiated today within the historic Kuhn tungsten area.
Strong historical drill results: Historical drilling at Kuhn reportedly returned intervals including 13.0 metres grading 0.55% WO₃, 11.3 metres grading 0.59% WO₃ and 0.10% MoS₂, and 4.0 metres grading 1.32% WO₃ and 0.26% MoS₂.
Historical tungsten estimate: Historical work outlined approximately 616,500 tonnes grading 0.48% WO₃ across the Kuhn and Dead Goat areas.*
Modern exploration opportunity: The 2026 program will test historically identified tungsten-bearing zones using modern geological and geophysical information.
District-scale opportunity: Kuhn represents the first phase of a broader drill program evaluating multiple styles of mineralization across the approximately 37,000-hectare Magno Project.
Rob Birmingham, President and CEO of GoldHaven, commented:
“Commencing drilling at Magno is an important milestone for GoldHaven. We are starting at Kuhn, where compelling historical tungsten intercepts provide us with a strong foundation for our first drill program and an opportunity to evaluate the system using modern exploration techniques. With tungsten becoming increasingly important to secure critical-mineral supply chains, we believe Kuhn is a timely and exciting place to begin. Importantly, it represents just one target within the much larger polymetallic system we are exploring across Magno.”
Drilling Begins at Kuhn
The first drill hole is designed to test the Kuhn tungsten target, where historical exploration identified multiple zones of tungsten mineralization associated with scheelite.
Historical drilling at Kuhn reportedly returned several significant tungsten-bearing intervals, including:
13.0 m grading 0.55% WO₃
11.3 m grading 0.59% WO₃ and 0.10% MoS₂
6.0 m grading 0.58% WO₃
4.4 m grading 0.75% WO₃ and 0.17% Cu
4.0 m grading 1.32% WO₃ and 0.26% MoS₂
These historical results provide GoldHaven with a compelling starting point for the maiden drill campaign. The Company’s objective at Kuhn is to test the geometry and continuity of the tungsten-bearing zones while obtaining modern geological, structural and geochemical information that can be incorporated into the broader Magno exploration model.
Historical work at the Kuhn and nearby Dead Goat areas also produced an estimate of approximately 616,500 tonnes grading 0.48% WO₃ across four modelled lenses.*
The historical estimate includes approximately 409,300 tonnes grading 0.48% WO₃ at Kuhn North Lower 3A; 78,700 tonnes grading 0.50% WO₃ at Kuhn North Upper 3A; 100,900 tonnes grading 0.49% WO₃ at Dead Goat; and 27,600 tonnes grading 0.39% WO₃ at the Dead Goat Deeper Lens.
*The historical estimate is not a current mineral resource or mineral reserve. A Qualified Person has not completed sufficient work to classify the historical estimate as a current mineral resource or mineral reserve, and GoldHaven is not treating the historical estimate as current.

Tungsten’s Growing Strategic Importance
Tungsten is recognized as a critical mineral because of its unique combination of exceptional hardness, high density and the highest melting point of any metal. These properties make tungsten difficult to substitute in many applications, including cutting and drilling tools, wear-resistant industrial components, aerospace technologies, electronics and defence applications.
The strategic importance of tungsten has increased as governments and industry focus on establishing more secure and diversified critical-mineral supply chains. Global tungsten production and processing are highly concentrated, increasing the importance of identifying and advancing potential new sources of supply in stable mining jurisdictions.
Canada has placed growing emphasis on developing domestic and allied critical-mineral supply chains to support economic security, advanced manufacturing and defence. GoldHaven believes the historical tungsten mineralization at Kuhn provides a compelling opportunity to evaluate a potential Canadian source of tungsten while advancing the broader polymetallic potential of the Magno Project.
Broader Magno Exploration Program
While Kuhn is the starting point for the 2026 drill campaign, GoldHaven’s exploration thesis extends well beyond tungsten.
The approximately 37,000-hectare Magno Project hosts multiple styles of mineralization and numerous historical workings and exploration targets. Recent exploration has identified high-grade silver, lead, zinc, tungsten and other metal occurrences across the property.
The Company intends to systematically evaluate priority targets during the 2026 program while integrating drilling results with geological mapping, geochemistry and the Company’s recently completed airborne geophysical survey.
Historical Estimate and Drilling Disclosure
The historical estimate referenced herein is historical in nature and was derived from historical exploration records and reports. A Qualified Person has not completed sufficient work to classify the historical estimate as a current mineral resource or mineral reserve, and GoldHaven is not treating the historical estimate as a current mineral resource or mineral reserve. Additional drilling and technical work would be required to verify the historical estimate and potentially classify mineralization in accordance with current NI 43-101 standards.
The historical drilling results referenced herein have not been independently verified by GoldHaven and should not be relied upon as current results. The planned drill program is intended, in part, to test and verify the historically reported mineralization.
