Announcement PDF 25 June 2025 Additional Drill Rig Secured for Enlarged Drill Program at the Christmas Creek Gold Project DDH1 diamond drill rig scheduled to arrive on site in the coming weeks Highlights • Drill contractor DDH1 engaged to undertake diamond core drilling at Christmas Creek to allow for deeper exploration targeting and to obtain detailed structural information relating to gold mineralisation. • Diamond rig scheduled to arrive on site early July. • Current RC drilling is ongoing, targeting extensions to the previously reported high-grade intervals at the Martin prospect in drill-hole 24XRC097, including: ▪ ▪ 10m @ 12.66g/t Au from 59m; and 10m @ 7.34g/t Au from 94m • Initial batch of RC assays are expected to be received in mid to late July 2025. • Heritage surveying recently completed, paving the way to test additional targets during the current drilling program.

Trek Metals Limited (ASX: TKM) (“Trek” or the “Company”) is pleased to advise that the Company’s high-impact exploration program at the Christmas Creek Gold Project in the Kimberley region of Western Australia has been expanded, with a second drilling contractor, DDH1 Drilling, engaged to provide diamond core drilling services in addition to the Reverse Circulation (RC) program currently underway (Figure 1). Trek Metals’ CEO Derek Marshall, said: “The securing of this second rig to undertake diamond drilling at Christmas Creek represents an exciting milestone, providing the opportunity to get down deeper into the system and obtain a much clearer picture of the geology and structural controls of the gold mineralisation. “The initial RC holes have been drilled underneath, down-dip and along strike from the highgrade intercepts achieved at the Martin Prospect last year, as we aim to fully delineate what we believe to be a significant stacked high-grade vein system. “The RC drilling is on-going, and we expect to test several prospects over the coming weeks. “We look forward to seeing what the current round of drilling reveals, with the first round of assay results expected to be reported to the market in the coming weeks.” The diamond drill rig is expected to arrive on site in the coming weeks, with the initial diamond program targeting the Martin Prospect area. Diamond drilling will enable Trek to undertake deeper exploration targeting at Christmas Creek and obtain detailed structural information relating to the gold mineralisation. The diamond drilling will be undertaken in parallel with the RC program that commenced at Christmas Creek in early June (see ASX Announcement 5 June 2025). This RC drilling is currently targeting the areas around, beneath and along strike from the high-grade intercepts reported at the Martin Prospect in drill-hole 24XRC097, including: • • 10m @ 12.66g/t Au from 59m; and 10m @ 7.34g/t Au from 94m Initial assay results from the RC drilling are expected to be reported in mid to late July. 2 Figure 2: Continental scale context and location map for the Christmas Creek Project, located at the intersection of G3 and G5 metallogenic lineament corridors, potentially representing the intersection of the Granites-Tanami Orogen & the Halls Creek Orogen. Christmas Creek Project (Kimberley, Western Australia) Located south-west of Halls Creek, the Christmas Creek Project comprises a previously unexplored, largely concealed district-scale gold and rare earths exploration opportunity in the Kimberley region of WA associated with major continental-scale tectonic lineament intersections. The Christmas Creek Project was previously part of Newmont Exploration Pty Ltd’s (Newmont) global exploration portfolio, with Trek acquiring the project in December 2023. The Company has also secured additional tenement applications to add to this district-scale greenfields gold and rare earths exploration project. 3 Authorised by the Board of Directors ENDS For further information contact: INVESTORS: MEDIA: Derek Marshall Nicholas Read dmarshall@trekmetals.com.au info@trekmetals.com.au 0419 929 046 JOIN TKM’S INTERACTIVE INVESTOR HUB https://trekmetals.com.au/auth/signup Interact with Trek Metal’s announcements and updates by asking questions and comments which our team can respond to where possible https://trekmetals.com.au/link/vPnl4e COMPETENT PERSONS STATEMENT The information in this report relating to Exploration Results is based on information compiled by the Company’s Chief Executive Officer, Mr Derek Marshall, a Competent Person, and Member of the Australian Institute of Geoscientists (AIG).
