Viking Mines Limited (ASX: VKA, OTC: VKALF) ("Viking" or "the Company") is pleased to advise it has executed a drilling services contract with DrilCor for the recently approved 63-hole maiden Reverse Circulation (RC) drilling programme at the Linka Tungsten Project in Nevada, USA. The contract award follows the recent receipt of US Bureau of Land Management (BLM) approval for the maiden drilling campaign, with the appointment of DrilCor representing the final operational milestone ahead of mobilisation. With permitting complete and the drilling contractor now locked in, Viking's focus shifts to site preparation and rig mobilisation logistics. Viking Mines Managing Director & CEO Julian Woodcock said: "Locking in DrilCor is a significant step forward in our fast-to-market strategy at Linka. With permitting complete and our drilling contractor now under contract, the team is squarely focused on getting the rig to site and breaking ground on what will be the first known drill testing at Linka in more than 40 years. "The maiden campaign is designed to deliver across three distinct objectives, verifying historic high-grade intercepts at Linka Main, maiden testing of the prospective southwest extension, and regional reconnaissance across the broader claim package. Each target has the potential to materially advance our understanding of the Linka mineralised system. "With drilling scheduled to commence late in the June quarter and assay results from our recent field campaigns expected over the coming months, Viking has a strong period of news flow ahead, all underpinned by a fully-funded balance sheet." 1 Refer VKA ASX Announcement 24 April 2026 — March 2026 Quarterly Activities Report and Appendix 5B. 2 ASX:VKA, OTC:VKALF | vikingmines.com PROGRAMME OVERVIEW The approved campaign comprises 63 holes from 48 drill pads across three target objectives: • Linka Main (36 holes): Resource-focused testing to verify historic high-grade intercepts and target down-dip continuity beneath historic workings. • Linka SW Extension (16 holes): Two Maiden testing across four sections at 125–150m spacing of the prospective ~800m southwest extension (Figure 1). • Regional Reconnaissance (11 holes): Shallow vertical holes to validate magnetic and gravity geophysical interpretations and define contact positions prospective for new mineralised zones.
