Viking Mines (ASX:VKA) Engages Mineral Technologies for Linka Tungsten Processing Study

Highlights

• Viking Mines has engaged Mineral Technologies to conduct a processing concept study for the Linka Tungsten Project in Nevada.
• The study will evaluate metallurgical characterisation, flowsheet design, and modular processing solutions.
• Mineral Technologies brings more than 80 years of experience in gravity separation and mineral processing.
• The project will examine modular plant options using Mineral Technologies’ proprietary FlexSeries technology.
• Ongoing work includes metallurgical testing, procurement planning, and concept-level cost estimates.

Viking Mines Ltd (ASX:VKA) has taken a step toward advancing the Linka Tungsten Project in Nevada, United States, with the early engagement of global mineral processing specialist Mineral Technologies, a subsidiary of Downer Group. The collaboration comes as metallurgical testwork indicates that the project’s mineralisation is amenable to gravity separation, prompting the company to begin engineering studies aimed at defining a low-capital cost processing pathway.

Processing Study Underway

Mineral Technologies has been engaged to undertake a processing concept study, including metallurgical characterisation, flowsheet design, and evaluation of modular processing alternatives.

The work will assess processing methods that could support efficient tungsten recovery while examining approaches that may reduce the capital and operational intensity often associated with conventional fixed processing plants.

Through specialist expertise in tungsten recovery, the study will evaluate processing pathways designed to maximise WO₃ recovery rates from Linka mineralisation.

Mineral Technologies Brings Global Tungsten Processing Expertise

Mineral Technologies has supported several tungsten developments globally and has provided process equipment, technology, and engineering design for projects across Australia and Europe.

Because tungsten ore is often freely liberated, flowsheet design can focus on reducing unnecessary grinding and material handling while maintaining recovery efficiency.

A central component of the engagement involves assessing the use of a modular processing plant using Mineral Technologies’ FlexSeries technology.

FlexSeries plants use pre-assembled modules that are constructed offsite before being transported for installation. The modular design is intended to shorten construction timelines compared with traditional processing plants.

Pre-assembled modules can reduce delays associated with labour availability, missing components, or weather conditions during onsite construction.

The compact design also allows for potential expansion or relocation of modules as project requirements evolve. Mineral Technologies has installed FlexSeries plants in Australia and the United States and is currently delivering three similar plants in South Africa.

Advancing the Linka Tungsten Development Pathway  

The engagement forms part of Viking Mines’ broader strategy to progress exploration assets toward potential commercial production pathways.

By combining tungsten mineralisation within its Nevada portfolio with a modular processing design, the company is assessing development models that could support scalable production.

Upcoming Work Programs at the Linka Project

Following the engagement of Mineral Technologies, Viking Mines will continue several technical workstreams at the Linka Tungsten Project.

• Metallurgical testing will continue to refine gravity separation parameters and assess additional recovery through flotation of gravity tails.
• The study will also define the processing flowsheet and deliver a technical blueprint for a modular processing solution.
• Additional work will include evaluating FlexSeries module specifications, assessing procurement timelines for site deployment, and preparing concept-level capital and operating cost estimates.
