Viking Mines Ltd (ASX:VKA) has advanced its understanding of the Linka Tungsten Project in Nevada, USA. It followed expanded geophysical surveys that revealed a broader system than previously identified, shaping upcoming drilling plans.
The company reported that an expanded ground magnetics geophysical survey has improved its knowledge of the Linka Tungsten Project. The survey indicates that the project forms part of a significantly larger intrusive system than previously interpreted. This updated insight provides a clearer technical framework for the company’s planned drilling programme in the June quarter.
Sharper Targeting Approach
The geophysical programme aimed to extend beyond known surface mineralisation and define the limits of intrusive bodies and their contact with surrounding sedimentary rocks. By applying high-resolution magnetic surveys, Viking has developed a targeting model designed to identify concealed or “blind” mineralisation beneath younger geological cover.
Three survey methods were deployed to map the intrusive architecture and refine drill targeting. The resulting dataset supports a more structured approach to exploration, focusing on areas with a higher probability of mineralisation.
Targets Beneath Cover
A key outcome from the survey is the identification of a southern extension of the system beneath the Bates Mountain volcanic cover. Ground magnetics data has enabled interpretation of subsurface features, highlighting a prospective contact zone between the intrusive body and limestone host rocks.
This newly identified horizon is expected to guide future drilling, with plans to test these concealed targets and assess the broader scale of the Linka system beyond visible surface expressions.
Next Steps in Exploration
The company has outlined several steps to progress exploration. These include completing the processing of gravity and GAIP datasets and integrating all geophysical data into 3D geological models for precise target generation. Field crews are scheduled to mobilise in April to conduct mapping and sampling, validating interpretations from the geophysical work.
Viking Mines is also finalising a drilling programme to test findings across the largely untested intrusive contact zone, which represents approximately 89% of the target area. Drill permitting is expected to be completed ahead of planned drilling activities in the June quarter.
Board Update
Viking Mines also announced the resignation of Non-Executive Director Bevan Tarratt, effective 31 March 2026. He will continue to support the company through a consulting agreement, providing strategic advisory services as required.
