Highlights
- Viking Mines has commenced field operations at the Linka Tungsten Project, mobilising a team to evaluate historical stockpiles and tailings.
- The programme targets a near zero-mining-cost opportunity for potential short-term commercialisation options.
- Systematic sampling of the tailings dam and ore stockpiles is underway to determine grade, volume, and reprocessing potential.
- Metallurgical testwork has achieved a 63.6% WO₃ concentrate, with further studies ongoing to define processing costs and plant scalability.
- Upcoming Phase 2 activities will support a maiden drilling campaign planned for the June quarter.
Viking Mines Limited (ASX:VKA) (OTC:VKALF) has commenced field operations at its Linka Tungsten Project in Nevada. A field team has been mobilised to launch a multi-faceted programme focused on evaluating historical ore stockpiles and tailings dam.
The company highlighted that this programme represents a a near ‘zero-mining-cost’ opportunity to explore short-term commercialisation options that avoid conventional extraction expenses.
Stockpiles and Tailings Assessment in Progress
The programme includes systematic grid sampling to determine grade and volume of the tailings, with approximately 52 samples being collected from the tails’ dam. This work is intended to evaluate whether the material can be reprocessed as a low-cost supplemental feedstock for future "Rapid-Start" modular plant.
Sampling is underway on historical ore stockpiles to evaluate grade consistency, building on previous composite sampling which returned 0.8% WO₃. Current efforts also aim to estimate total stockpile tonnage. Through stockpile, the company intends to assess near-term processing opportunities through toll treatment or pilot plant to generate concentrate samples to support potential offtake discussions.
Metallurgical Testwork Advances Processing Study
Metallurgical programmes continue alongside field activities to support an ongoing processing concept study. Recent testwork has reported 53-fold upgrade to produce a 63.6% WO₃ concentrate.
Additional samples are being collected for comminution testing, which will assist in defining the project’s operational costs and will ensure modular plant scalability.

Geological Validation and Phase 2 Planning
Initial field investigations are also validating targets identified through three-dimensional geological modelling and geophysical surveys. Work is focused on confirming an 820-metre mineralised corridor and 800-metre extension beneath cover.
Phase 2 of the programme is scheduled to begin later in April and will include detailed follow-up mapping, trench & outcrop sampling, and finalisation of precise collar locations. Preparations are also underway to support a maiden drilling campaign planned for the June quarter.
Ongoing fieldwork, metallurgical testing, and geological validation are progressing in parallel at the Linka Tungsten Project. With Phase 2 activities and drilling preparations scheduled in the near term, the company continues to advance multiple workstreams aimed at defining resource potential and evaluating development pathways.
