GPM Metals Announces the Commencement of

a 3,000-metre Diamond Drill Campaign at the

Walker Gossan Project, Northern Territory,

Australia

Toronto, Ontario--(Newsfile Corp. - September 22, 2025) - GPM Metals Inc. (TSXV: GPM) (

"GPM"

or

the "

Company

") is pleased to announce the commencement of drilling at the Walker Gossan Project,

Northern Territory, Australia. The 3,000-metre drill program is designed to test several large, coincident,

gravity, radiometric and geochemical anomalies.

Kent Balas, GPM Exploration Manager commented "We are very encouraged by what we are seeing on

the ground, we see striking similarities to the published geology at MacArthur River. The GPM

Exploration Team has analyzed and sampled current and future target areas. Gossanous rocks have

been located proximal to the drill targets which has given the Company increased confidence in the

current drill campaign."

The Company wishes to thank the Traditional Owners who have approved this program and provided

extensive cultural clearances across the current exploration targets. The Company looks forward to

working with Cultural Monitors throughout the drill campaign to address any Cultural and Environmental

concerns. The Company also wishes to thank the Northern Land Council for their ongoing guidance and

assistance. The Walker Gossan Project has received additional support from the Northern Territory

Government by way of a AUS$150,000 grant via their "Resourcing the Territory" Initiative.

John Timmons, Chief Executive Officer commented "I want to thank our entire team and all stakeholders

for the progress we have made over the past months after a late rainy season in East Arnhem Land,

Northern Territory. The access road to site is in excellent condition and the drill is turning. After over a

decade of challenges, we are excited to be drilling these large untested gravity anomalies and move the

Walker Gossan Project forward."
