Viking Mines Limited (ASX: VKA, OTC: VKALF) ("Viking" or "the Company") is pleased to announce a significant step in the preparation for its maiden drilling campaign at the Linka Tungsten Project in Nevada, USA. The Company has formally lodged a Notice of Intent (NOI) with the Bureau of Land Management (BLM), completing the final federal regulatory requirements necessary to secure approval to launch a planned 63-hole programme. The programme will be the first exploration drilling for >40 years since last activity ceased in ~1980, kickstarting a past- producing tungsten asset into a US market structurally short of domestic supply. This campaign is designed to test the scale of the Linka system while confirming the high-grade nature of historical results to define a rapid pathway to resource definition and potential future development. The campaign positions Viking ahead of the December 2026 REEShore Act mandate, which bans Chinese-origin tungsten from US military supply chains. Viking Mines Managing Director & CEO Julian Woodcock said: “Lodging the NOI marks our transition to active sub-surface exploration. This 63-hole programme targets near-surface opportunities and the ~800m southwest extension, building a growth pipeline in a strategic US tungsten district. We are in the final stages of contractor selection and remain on track for mobilisation in June.” DRILLING OBJECTIVES AND TARGET AREAS The planned drilling programme exploration is an extensive campaign focusing on 3 distinct technical objectives aimed at unlocking significant value (Figure 1): Linka Main: Near-Surface Opportunity Resource Testing Activity at Linka Main is dedicated to confirming historical drilling intercepts and conducting close-spaced testing of near-surface mineralisation. This work is essential to ascertain the immediate mining opportunity. 2 ASX:VKA | vikingmines.com Figure 1; Map showing the Linka Project and planned drillhole locations with magnetic geophysics background image. Note the 3 different target objectives from the drill hole programme. 3 ASX:VKA | vikingmines.com The drilling will test and verify high-grade historical intercepts at Linka Main including: • Drillhole DH-04: 9.8m at 0.5% WO3. • Drillhole LR-11: 7.9m at 0.9% WO3. • Channel sample: 8.5m at 1.0% WO3. Additional drilling will test down-dip of the historical workings to establish the depth potential of the system. Linka Southwest: System Extensions The Company will test for extensions of the Linka Main mineralisation where it continues beneath the younger shallow cover to the southwest of Linka Main. This high-potential area will be tested over 4 sections spaced between 125m to 150m apart to establish the bedrock geology and determine the continuity of the skarn mineralisation. Regional Reconnaissance: Geophysical Validation Reconnaissance drilling will investigate the extents of the regional intrusive interpreted from magnetic and gravity geophysics. Shallow vertical holes will test the thickness of cover to reach the underlying bedrock, verifying the geophysical interpretation and seeking to define contact positions where mineralisation typically occurs. This represents an essential first step in a multistage process to identify new mineralised zones for subsequent follow-up testing across the broader Linka intrusive complex. Timeline and Mobilisation The Company anticipates receiving the required approvals from the Federal Government in May 2026. Viking is currently in the final stages of securing a drilling contractor to ensure the most capital and time efficient execution of the programme. Subject to obtaining the necessary approvals from the federal government, site mobilisation to commence drill site preparation and earthworks ahead of drilling is scheduled for the June quarter, marking a pivotal shift into active sub-surface development for the Nevada tungsten assets.
