A 500%+ Metal, a Historic Tungsten Zone, and a Drill Program About to Test Both

VANCOUVER, British Columbia, June 03, 2026 (GLOBE NEWSWIRE) — Equity-Insider.com
News Commentary — Few metals have repriced as violently as tungsten. Since China added tungsten products to its export-control list in February 2025, the benchmark price of ammonium paratungstate (APT) has surged more than 500%, pushing toward roughly US$2,250 per metric tonne unit by early 2026 — outpacing gold and copper, and forcing every Western government and defense contractor to ask the same question: with China still controlling more than 80% of global tungsten production, where does the next non-Chinese supply come from? That question is now pointing capital toward companies sitting on historically defined, Western-jurisdiction tungsten — and one junior is about to put a drill bit into exactly that.

On June 2, 2026, GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) detailed a fully funded 2026 diamond drill program aimed squarely at the historic Kuhn tungsten zone on its 100%-owned, district-scale Magno Project in the Cassiar District of northern British Columbia — a program designed to verify and expand a tungsten-bearing skarn system that previous operators had already partly outlined decades ago.

Drilling into a head start

What makes the Kuhn program notable is that GoldHaven is not drilling blind. Historical exploration by previous operators — drilling, underground development, geological mapping and lens modelling — already outlined a historical estimate of approximately 616,500 tonnes grading 0.48% WO₃ across four modeled mineralized lenses at the Kuhn and Dead Goat areas. The company is careful to note this is a historical estimate, not a current mineral resource: a Qualified Person has not done sufficient work to classify it under current standards, and GoldHaven is not treating it as a current resource or reserve. But as a framework for where to point the drill, it is a meaningful head start over a greenfield target.

The historical drill intercepts are what give the zone its appeal. Previous drilling at Kuhn North returned multiple tungsten-bearing intervals, including 13.0 metres grading 0.55% WO₃, 11.3 metres at 0.59% WO₃ with 0.10% MoS₂, and a standout 4.0 metres grading 1.32% WO₃ and 0.26% MoS₂ — with mineralization outlined over a vertical extent exceeding 100 metres across several modeled skarn lenses. GoldHaven cautions that it has not independently verified these historical results; verifying them is, in fact, one of the explicit goals of the upcoming program.

“The Kuhn Zone represents an exciting opportunity to evaluate a historically defined tungsten-bearing skarn system at a time when demand for critical minerals continues to increase,” said Rob Birmingham, Chief Executive Officer of GoldHaven. “Our fully funded 2026 drill program is designed to verify previous drilling, test extensions of known mineralization, and improve our understanding of what we believe could be a larger tungsten-molybdenum system. With multiple mineralized lenses identified and indications that the system remains open at depth, we believe Kuhn has the potential to become an important critical minerals target within the Magno Project.”
