 VANCOUVER, British Columbia, June  17, 2025  (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (“GoldHaven”  or the “Company”) (CSE: GOH | OTCQB: GHVNF | FSE: 4QS) is pleased to  announce that it has entered into an agreement to acquire the Kuhn, Dead  Goat, and M3 claims (the “Claims”) located in northwestern British  Columbia, within the Company’s flagship Magno Project. The claims total  1,100.6 acres and host a historic resource of 409,300 tonnes at 0.48%  WO3 (tungsten trioxide) and 0.134% MoS2 (molybdenum disulfide) in the  Kuhn North zone. These estimates are historical in nature and do not meet NI 43-101 standards and therefore should not be relied upon.
 
 Tungsten: A Critical Mineral of Strategic Importance to North America
 
 Tungsten  has emerged as a critical mineral of strategic importance due to its  unmatched physical properties and indispensable role in high-performance  applications. With the highest melting point of any metal and  exceptional density and hardness, tungsten is essential to modern  defense systems, including armor-piercing munitions, kinetic energy  penetrators, and aircraft turbine components. Its resilience to extreme  temperatures and wear makes it equally vital in aerospace, advanced  manufacturing, and nuclear energy. These characteristics, combined with a  lack of viable substitutes, position tungsten as a cornerstone of  national security and industrial competitiveness.
 
 However,  the global tungsten supply chain faces a significant geopolitical risk.  China, which controls over 80% of global tungsten production and  refining, enacted strict export controls in February 2025 that have  effectively halted shipments of key tungsten products. Though not an  outright ban, China has issued no export licenses under the new regime,  creating a de facto blockade that has shocked global markets and driven  to increased prices and supply uncertainty. This move highlights the  urgent need for diversified, secure tungsten supply chains as Western  nations confront the strategic vulnerabilities of relying on a single  dominant supplier for such a critical resource. Analysts anticipate that  Chinese-supplied tungsten may be scarce in the global markets driving  companies and countries to explore for alternative sources and  strategies to mitigate the impact of China's export controls.
 
 Acquisition Highlights:
 
 
 The  Kuhn and Dead Goat properties are in the Cassiar Mining District,  British Columbia, and have been explored since at least the 1970s.Historic  drilling by Shell Canada included 17 diamond drill holes totaling 1,766  metres, confirming the presence of high-grade scheelite (CaWO4) and  molybdenite (MoS2).Well-developed skarn-type mineralization system.Recent  exploration has confirmed significant tungsten and molybdenum  mineralization in metasomatic skarn lenses, with ongoing potential for  resource expansion.Historical Resource Estimates:
 
 
 | Zone | Tonnes | % WO3 | % MoS2 | % Cu |  | Kuhn North, Lower 3A Band | 409,300 | 0.48 | 0.134 | - |  | Kuhn North, Upper 3A Band | 78,700 | 0.5 | - | - |  | Dead Goat | 100,900 | 0.49 | - | - |  | Dead Goat (deeper lens) | 27,600 | 0.39 | - | 0.16 |  | Total | 616,500 | - | - | - | 
 
 
 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

 Terms of the Acquisition:
 
 GoldHaven  has entered into a title transfer agreement (the “Agreement”) dated  June 12, 2025 with Fundamental Resources Corp. (the “Vendor”), pursuant  to which it is entitled to acquire a 100% interest in the Claims located  in the Cassiar Mining District, British Columbia (the “Transaction”).  As consideration, the Company will issue 1,250,000 common shares (the  “Consideration Shares”) to the Vendor, subject to a 36-month escrow  release schedule pursuant to which 10% of the Consideration Shares will  be released on completion of the Transaction, and 15% on each six month  anniversary thereof. 100% of the Consideration Shares will be subject to  the standard Canadian statutory four month hold period. The Transaction  is expected to be completed on or about June 24, 2025.
 
 Rob Birmingham, CEO of GoldHaven Resources, stated: “We  are very pleased to expand our presence in this underexplored but  highly prospective region of British Columbia. The Kuhn, Dead Goat, and  M3 claims strengthen our strategic land position within the Magno  Project and introduce compelling tungsten upside with additional zones  of Copper, Zinc and Molybdenum to the GoldHaven story. The Kuhn and Dead  Goat deposits share a geological setting similar to Cantung and  Mactung, both large tungsten skarn deposits in Canada. This  strategic acquisition comes on the heels of continued strong demand for  commodities caught in the middle of global tariff battles—particularly  tungsten. Historic work by Shell Canada, coupled with more recent  exploration by Fundamental Resources, has highlighted the potential for a  high-grade skarn system that could support a future development  opportunity.”
 
 The Company plans to  conduct a detailed review of historic data and design follow-up  exploration programs to confirm and expand the known mineralization.
