Viking Mines Validates Sensor-Based Ore Sorting at Nevada Tungsten Project, De-Risking Linka Development

The Quick Take

• Viking Mines proved sensor-based ore sorting can successfully upgrade tungsten feed at its Nevada Linka project
• The technology successfully rejected barren waste rocks, improving ore grade without chemical processing
• A viable ore sorting solution at Linka de-risks Viking's path to economic tungsten production in Nevada

Viking Mines has demonstrated that sensor-based ore sorting can materially upgrade tungsten ore feed at its Linka project in Nevada, with the technology successfully distinguishing and rejecting barren waste rocks while concentrating mineralized material. Ore sorting is a pre-concentration step that improves feed grade before downstream processing, reducing the volume of material requiring energy-intensive milling and chemical treatment. For tungsten projects — which historically face high processing costs due to the mineral's complexity — a viable ore sorting solution represents a significant technical de-risking milestone that has direct cost and capex implications for project economics.

Tungsten is a critical mineral increasingly viewed through a strategic lens by Western governments seeking to reduce dependence on Chinese supply, which accounts for the majority of global tungsten production. Viking's Nevada-based Linka project positions the company within the growing Western critical minerals investment thesis, where ore sorting efficiency is a key differentiator between economically marginal and commercially viable deposits. The successful demonstration reduces processing capex requirements and may make the project more attractive to offtake partners or strategic investors in the defense and cutting-tool industries, where tungsten's unique hardness properties are irreplaceable.

Watch for Viking's next technical update on ore sorting throughput rates and recovery percentages, as these will determine whether the technology scales from demonstration to commercial-scale production. Feasibility study milestones and any partner or offtake agreement announcements are the key catalysts that would crystallize the value of the ore sorting result into tangible project advancement. The macro variable is Western government critical mineral incentives: accelerated IRA critical mineral tax credits or Defense Production Act designations for tungsten would significantly improve project economics and accelerate Viking's development timeline in a market where supply security has become a strategic imperative.
