GoldHaven Intersects New Skarn Zone at Kuhn; Drilling Underway from Second Pad

VANCOUVER, British Columbia, Sept. 24, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide an update on ongoing diamond drilling at the Company’s 100%-owned Magno Project in the Cassiar District of northern British Columbia.

Further to the Company’s September 15, 2026, drilling update, GoldHaven reports that GOH26-04 has now been completed following an extension of the hole beyond its originally planned termination depth. Continued drilling intersected a newly identified skarn zone beneath the down-dip extension described in the September 15 release. The drill has since been moved to a new pad (Pad B) at the Kuhn target, where three of the holes have been completed and drilling of the fourth from Pad B is underway.

Highlights

• GOH26-04 has been completed after being extended beyond its originally planned termination depth.
• Continued drilling intersected a new skarn zone beneath the previously reported down-dip extension at Kuhn.
• Drilling encountered a series of stockwork skarn mineralization zones from approximately 235 to 325m (drill length), followed by more continuous skarn mineralization from 345 to 400m.
• The newly identified intervals total approximately 145 metres of drill length, with true thickness currently interpreted at approximately 40-45 metres.
• The drill has now moved to a new pad at Kuhn and commenced drilling, continuing the systematic testing of the skarn system.
  

GOH26-04 Extended Following Geological Review

GOH26-04 was designed to test the down-dip continuation of the historically identified skarn system at Kuhn. Following review of the drill core by GoldHaven’s geological team, observations within the hole were considered sufficiently encouraging to warrant continuing drilling beyond the originally planned termination depth.

The decision resulted in the intersection of an additional skarn zone beneath the down-dip extension previously identified in GOH26-04.

Figure 1: Drill core from GOH26-04 at approximately 164–166m depth, showing skarn with locally semi-massive sulphide mineralization. The Company is continuing to log, sample and submit core for laboratory analysis.

The newly identified skarn intervals total approximately 145 metres of drill length. Based on the Company’s current geological interpretation, true thickness is estimated at approximately 40–45 metres, assuming the newly identified lower zone dips at a similar angle to the overlying stratigraphy and skarn units. This interpretation is preliminary and may be refined as additional geological and drilling information becomes available.

The skarn intervals display several mineralization styles, including magnetite skarn, garnet skarn, diopside skarn, and zones of semi-massive to massive sulphide mineralization. The skarnified intervals are hosted within a sequence of limestone, marble and dolomite.

The Company is continuing to log, photograph and sample the drill core, with samples being submitted for laboratory analysis. The September 15 release noted that core from the Kuhn program was being logged and sampled, with assays to be released once received, reviewed and verified.

Expanding the Geological Picture at Kuhn

The ongoing drill program is designed to improve GoldHaven’s understanding of the geometry, thickness and continuity of the skarn system through a series of modern drill sections across the Kuhn target.

The additional skarn encountered in GOH26-04 provides another important geological data point as the Company evaluates the development of the system beyond areas tested by historical drilling.

GoldHaven’s 2026 program represents the Company’s first modern, systematic drill campaign at Magno, with drilling initially focused on Kuhn before evaluating additional priority targets across the broader property.

CEO Comment

GoldHaven President and CEO Rob Birmingham commented:

“The decision to continue GOH26-04 was driven directly by what our geological team was seeing in the core, and that decision has now resulted in the intersection of an additional skarn zone beneath the down-dip extension we reported last week.

“We are encouraged to continue seeing skarn development as we test the Kuhn system at depth. While assays will ultimately determine the significance of these intervals, each hole is materially improving our understanding of the geometry and scale of the system and helping us refine where we drill next.”

Ongoing Drill Program

With GOH26-04 now complete, the drill has been moved to a new pad (Pad B) at the Kuhn target where three of the four planned drill holes have been completed.

Integration of observations from the latest drill holes, notably GOH26-04, historical geological information and modern geophysical data to refine subsequent drill targeting remains ongoing.

Further updates will be provided as drilling advances and laboratory results are received, reviewed and verified.
