GPM Metals Advances District-Scale Sediment Hosted Massive Sulphide Exploration at Walker Gossan Project and Strengthens Technical Team for Next Phase of Growth

GPM Metals Inc. (GPM) has released results from a 2,500-metre diamond drill program conducted at its Walker Gossan Project in the Northern Territory of Australia. The company disclosed a single mineralized intercept from the campaign, with hole WGD25003 intersecting 5 metres grading 0.63% zinc, 0.027% lead, and 0.64 grams per tonne silver from a depth of 781 metres. This interval is hosted within pyritic black shales of the Zamia Creek Siltstone.

The company highlighted ferroan dolomite alteration as a distal indicator and claimed stratigraphic correlation to the host rock of the McArthur River (HYC) deposit. No other assay intervals, cutoff grades, true widths, or quality assurance and quality control details were provided for the intercept.

GPM Metals has appointed former Rio Tinto geologists Roger Norris and Hilke Dalstra as consultants. The company also outlined a ground-geophysics and mapping program scheduled for 2026–2027.

GPM Metals Inc. (GPM) is a grassroots explorer whose equity thesis previously rested on the potential for a world-class SEDEX discovery at Walker Gossan. The company reported a 5 m @ 0.63% Zn intercept, a result that effectively falsifies the near-term target that assay results would show significant zinc mineralization in the disseminated sulphide zones.

The stock price fell from a high of C$0.22 in May 2026 to C$0.10 immediately before this news, reflecting market distrust; the weak intercept confirms the negative sentiment. The appointment of experienced consultants and a new exploration plan for 2026-2027 does not compensate for the absence of an economic discovery — it merely signals the company is pivoting to a longer-term prospect with depleted cash. This release is materially negative because it demonstrates that the primary anomalies tested to date lack ore-grade zinc mineralisation, severely damaging the investment thesis for the Walker Gossan Project.

GPM Metals Inc. is a TSX Venture-listed junior explorer holding the Walker Gossan Project in Australia’s Northern Territory, covering 1,935 sq km in the prospective McArthur Basin. The project targets SEDEX Zn-Pb-Ag deposits analogous to McArthur River (HYC) and Teena.

As of Sept 30, 2025, the company held cash of C$1.69 M with negative operating cash flow and minimal other assets. A C$1 M private placement closed in Feb 2026 at C$0.075 per unit, likely sustaining operations through mid-2026. The company has no revenue and equity is heavily diluted with 153 M shares post-placement.

Management and Board include CEO John Timmons, CFO Yajian Wang, and several directors. Newly appointed consultants Roger Norris and Hilke Dalstra add credibility but bring no immediate resource.
