Toronto, Ontario--(Newsfile Corp. - September 1, 2026) - Stakeholder Gold Corp. (TSXV: SRC) (OTCQX: SKHRF) (WKN: A2QEP1) ("Stakeholder" or the "Company") is pleased to report the final diamond drill assay results for hole BA2601, completing a fully mineralized 498-metre discovery hole at the Loki Critical Mineral Zone on its 100%-owned Ballarat Gold-Copper Project ("Ballarat") in the prolific White Gold District of the Yukon Territory. Stakeholder also reports significant results from the three-dimensional (3D) inversion modelling of the Company's VTEM (electromagnetic) and magnetic geophysical data over the Loki area (Figures 1–4).

The newly received assays cover the upper (1–226 m) and lower (451–498 m) portions of hole BA2601, completing the full 498-metre hole and confirming mineralization throughout. The additional data show that copper-nickel-cobalt and platinum-group-element (PGE) mineralization extends through much of the upper hole, hosted in the same mineralized pyroxenite intrusion reported in the central interval on August 18, 2026. New and previously released intervals are summarized in Table 1; the property and the location of hole BA2601 are shown in Figure 1, and the completed hole in cross-section in Figure 2.

Highlights

• Full hole completed – mineralized top to bottom: Final assays complete the 498-metre hole (BA2601), confirming broad mineralization through the upper hole and materially extending the copper-nickel-cobalt-PGE system defined in the initial (226–451 m) release.

• Standout upper-hole copper-nickel-cobalt grades: New intervals underscore the strength of the system, including 3 m at 110–113 m of 1,650 ppm Cu, 266 ppm Ni and 127 ppm Co (including 1 m at 111–112 m of 2,390 ppm Cu), 13 m at 91–104 m of 670 ppm Cu, 2 m at 133–135 m of 1,020 ppm Cu, and 1 m at 141–142 m of 1,180 ppm Cu.

• Compelling platinum-palladium credits: The upper hole delivered 2 m at 98–100 m of 316 ppb Pt+Pd and 3 m at 141–144 m of 191 ppb Pt+Pd (including 2 m of 252 ppb Pt+Pd), directly associated with the copper-nickel-cobalt mineralization.

• 3D inversions define a major new target: Independent 3D inversions of the VTEM and magnetic data confirm BA2601 was collared in a large, coincident magnetic and resistive body – interpreted as the mineralized ultramafic intrusion – while a separate, ~1.45 km² conductive zone lies just ~1.4 km to the south, representing a compelling, entirely untested geophysical target for follow-up.

Full-Hole Results Confirm Broad Mineralization – BA2601 (Loki Critical Mineral Zone)

Hole BA2601 was drilled to 498 metres to test the Loki Critical Mineral Zone, and with the newly received upper- and lower-hole assays, the hole is now complete and confirms mineralization from end to end. Mineralization occurs as disseminated, blebby and locally net-textured to massive magmatic sulphides (pyrrhotite, pentlandite and chalcopyrite) within a broad pyroxenite intrusion, and the additional assays demonstrate that anomalous copper, nickel and cobalt, together with platinum and palladium, continue through much of the upper hole. Selected newly reported intervals are summarized in Table 1; the previously released central interval (226–451 m, reported August 18, 2026) is indicated on the cross-section in Figure 2.

Table 1: BA2601 intercepts at cut-offs of 500 ppm Cu (copper zones) and 50 ppb Pt+Pd (PGE zones); "including" sub-intervals at 2,000 ppm Cu / 100 ppb Pt+Pd. An asterisk (*) marks intervals between 226 and 451 m that were previously released on August 18, 2026; all other intervals are newly reported. Grades are length-weighted averages; copper, nickel and cobalt in ppm and platinum and palladium in ppb. Reported intervals are drill-core lengths; true widths are not yet determined.

3D Geophysical Inversion Results Define a Major New Target

The Company has received preliminary results from independent three-dimensional inversions of its airborne VTEM (versatile time-domain electromagnetic) and airborne magnetic datasets over the Loki area. The magnetic susceptibility inversion resolves a large, coherent magnetic body at Loki, into which hole BA2601 was collared, and the VTEM resistivity inversion shows this same body is relatively resistive – a signature consistent with a sulphide-bearing ultramafic intrusion. The preliminary 3D models are shown in Figure 3.

In plan view, the magnetic and resistive Loki body is spatially distinct from a ~1.45 km² conductive zone that the VTEM inversion places approximately 1.4 kilometres to the south (Figure 4) – opening up a second, entirely untested target within the system. The coincident magnetic-resistive signature at Loki is consistent with a sulphide-bearing ultramafic intrusion, while the separate southern conductor represents a discrete, untested geophysical target for future drill testing.

"Our first drill hole into Loki confirms a large ultramafic intrusion carrying copper, nickel, cobalt and platinum and palladium - a critical mineral suite found on almost all the world's critical mineral lists," stated Christopher Berlet CEO and Director of Stakeholder.

"Geophysics has now also confirmed that large, untested conductive anomalies are located nearby and within the intrusive structure itself. Our next steps are to: refine the geophysical targets that have already been identified, drill test the conductive anomalies found near to our first metal discovery hole and continue the work required to identify similar structures along the full 35-km trend of the Loki ultramafic intrusion which is found on the southern section of Stakeholder's 100% titled land position in the center of the rapidly evolving White Gold District."

Sampling and Quality Assurance / Quality Control

Drill core from hole BA2601 was logged, photographed and sampled at the core facility in Dawson, Yukon, where the core was sawn in half and one half was submitted for analysis at one-metre sample intervals. Samples were sent to the Bureau Veritas (BV) preparation laboratory in Whitehorse, Yukon, where they were crushed, and a split was pulverized to 85% passing 200 mesh.

At the BV laboratory in Vancouver, British Columbia, platinum, palladium and gold were determined by 30-gram fire assay with an ICP-ES finish (BV method FA350), and copper, nickel, cobalt and additional elements by 1:1:1 aqua-regia digestion with an ICP-ES/MS finish (BV method AQ201). Bureau Veritas Commodities Canada Ltd. is an ISO/IEC 17025-accredited laboratory that is independent of the Company. As part of its quality-assurance / quality-control program, the Company inserts certified reference materials (standards), blanks and duplicate samples into the sample stream and reviews all quality-control results upon receipt of assays.

Adam Fage, M.Sc., P.Geo. states:

"The completed BA2601 assays confirm that copper, nickel and cobalt, together with platinum and palladium, extend through a broad interval of the Loki ultramafic intrusion rather than being confined to a single zone. Coincident 3D magnetic and resistivity models show the intrusion is a large, discrete body, and the separate conductor to the south gives us a second, independent target. Our focus now is to use these results to vector toward higher-tenor sulphide accumulations within the system."
