Announcement PDF ASX ANNOUNCEMENT 18 May 2026 ASX:VKA vikingmines.com 15-17 Old Aberdeen Place West Perth, WA, 6005 P +61 8 6245 0870 F +61 8 9322 5230 contact@vikingmines.com 1 LINKA TUNGSTEN PROJECT MAIDEN DRILL CAMPAIGN FULLY PERMITTED • US Bureau of Land Management (BLM) approval received for Viking's maiden 63-hole drilling programme at the Linka Tungsten Project, Nevada. • Approval received ahead of the Company's internal timeline, providing certainty to lock in the drilling schedule. • Linka is fully permitted for drilling, with contractor selection the next scheduling milestone to be completed ahead of planned June quarter mobilisation. • 63-hole, 48-pad programme to deliver the first sub-surface exploration at Linka in over 40 years across three priority target areas. • Maiden drill testing to be completed of the ~800m southwest extension where surface samples have returned up to 0.6% WO3. • Verification of historic high-grade intercepts including 8.5m @ 1.0% WO3 at a project that produced ~65,000 tonnes @ 0.5% WO3 and ceased production 1956.1 Viking Mines Limited (ASX: VKA) ("Viking" or "the Company") is pleased to advise that it has received approval from the US Federal Bureau of Land Management (BLM) for the recently lodged Notice of Intent (NOI). With BLM approval secured, the Linka Tungsten Project is now fully permitted (upon payment of the required bonds) for the planned 63-hole maiden drilling programme. Approval was received ahead of the Company's internal timeline, clearing the final federal regulatory hurdle ahead of the planned June quarter mobilisation. Linka represents Viking's entry point into the US tungsten sector, a market structurally short of domestic supply. The December 2026 REEShore Act mandate, which prohibits Chinese-origin tungsten in US Department of Defense supply chains, reinforces the strategic context for advancing Linka toward drilling and resource definition. Viking Mines Managing Director & CEO Julian Woodcock said: "Receiving the BLM approval is yet another hurdle accomplished at Linka as we move towards the first known drilling at the Project for over 40 years. With our maiden campaign now fully permitted for drilling, the regulatory pathway is behind us, and the focus shifts entirely to finalising our drilling contractor and getting drilling underway. “We remain on track for our planned June quarter mobilisation to commence site preparations, and the team is moving at pace as we enter this exciting phase of activity. This is one of our key pillars in our fast to market strategy which will support the Projects development as we continue to advance in parallel the metallurgical testwork and processing concept study. “I look forward to continuing to update the market as we advance the Project" 1 Refer VKA ASX Announcement 16 December 2026 – VKA to acquire Production Proven USA Tungsten Projects 2 ASX:VKA | vikingmines.com Figure 1: Map showing the Linka Project and planned drillhole locations with magnetic geophysics background image.

With the permitting workstream now complete, the Company's near-term focus entails: • Finalising drilling contractor selection: With evaluations in their final stages, contract award expected shortly. • Drill site access and pad preparation works: To be undertaken in parallel with contractor mobilisation logistics and scheduled for commencement in June. • Drill Rig Mobilisation: Drill rig mobilisation to commence on contract award and anticipated arrival late in the June quarter, consistent with previously disclosed timing. APPROVED PROGRAMME The approved campaign comprises 63 holes from 48 drill pads across three distinct objectives, as detailed in the Company's ASX announcement dated 4 May 20262 : • Linka Main (36 holes): Resource-focused testing to verify high-grade historical intercepts including drillhole DH-04 (9.8m @ 0.5% WO₃), drillhole LR-11 (7.9m @ 0.9% WO₃) and channel sample 8.5m @ 1.0% WO₃, with additional holes targeting down-dip continuity beneath historical workings. • Linka SW Extension (16 holes): Maiden testing across four sections at 125–150m spacing of the prospective ~800m southwest extension, where surface sampling has returned grades up to 0.6% WO₃. • Regional Reconnaissance (11 holes): Shallow vertical holes to validate magnetic and gravity geophysical interpretations and define contact positions prospective for new mineralised zones across the broader Linka intrusive complex. The Company will update the market on contractor award and mobilisation logistics as those milestones are reached. END This announcement has been authorised for release by the Board of the Company.
