GoldHaven Resources Corp. has completed over 800 metres of drilling across four holes from its first pad at the historic Kuhn tungsten system within the Magno Project in northern British Columbia.

The 100%-owned project covers a district-scale land package of more than 37,000 hectares in the Cassiar District and serves as the company's flagship asset. Drilling at the Kuhn target commenced in late August 2026 to test the geometry, continuity, and potential extensions of historically identified tungsten-bearing skarn mineralization.

Initial drilling has encountered broad intervals of skarn alteration and sulphide mineralization within the top 100 metres. Notably, the second drill hole intersected an approximately 20-metre interval of skarn. Historical interpretation previously mapped two separate, narrower skarn bands, suggesting current work may define a broader and more continuous skarn package. Furthermore, the fourth drill hole has confirmed a previously unexplored down-dip extension of the skarn unit. Portable XRF analysis has indicated the presence of tungsten within the intersections, while core samples are logged and submitted for laboratory analysis.

“The first phase of drilling at Magno is doing exactly what we wanted it to do – giving us a modern look at a historically important tungsten system that has seen very limited exploration for decades. We are encouraged by the scale of the skarn alteration encountered in the early holes, particularly where drilling appears to show a broader package than suggested by the historical interpretation.” — Rob Birmingham, CEO of GoldHaven

Historical work at the Kuhn–Dead Goat system outlined an estimate of approximately 616,500 tonnes grading 0.48% WO₃ across four modeled lenses. Past drilling returned intervals including 13.0 metres grading 0.55% WO₃ and 11.3 metres grading 0.59% WO₃ with 0.10% MoS₂. These historical estimates and drill results pre-date National Instrument 43-101 and are not treated as current mineral resources or reserves.

Drilling remains ongoing at Kuhn to complete the planned drill fences. Following the completion of the first drill pad, the rig is scheduled to advance to a second pad along strike to complete approximately three to four additional holes. GoldHaven will release assay results from the current program as they are received, reviewed, and verified. Within the wider Cassiar district, activity has also advanced at neighboring properties, including an option agreement executed by Eagle Plains Resources Ltd. and Pacific Bay Minerals Corp. for the Haskins critical minerals project.
