- The company aims to strengthen its U.S. market presence through a proposed OTC listing and strategic government engagement.
Viking Mines Limited (ASX:VKA) has unveiled an intensive schedule of operational, technical, and corporate activities aimed at advancing its Linka Tungsten Project in the USA towards production. The company is moving from data consolidation into active on-ground development, supported by a series of metallurgical, geological, and engineering initiatives.
Accelerated Technical Programmes Underway
To de-risk the Linka Project, the company is using a targeted strategy that addresses metallurgical, geological, and engineering factors. Metallurgical work is continuing after achieving concentrate grades of up to 63.6% WO₃, with focus now moving to cleaner gravity and flotation processes. This aims at maximising recovery while ensuring marketable grades of >50% WO3.
Processing studies are also advancing, including TOMRA ore sorting to assess XRF and UV technologies alongside fine recovery assessments. The Mineral Technologies Processing Concept study is currently in progress, with a mid-project update due in late April. This study serves as a blueprint for a modular, "Rapid-Start" facility, providing initial CAPEX and OPEX estimates across various throughput scenarios.
Furthermore, sampling and evaluation of historical mineralised stockpiles and the tailing dam are planned for potential early development.
Geophysical Modelling and Field Activities Expand
The company is finalising a 3D geological model integrating historical and recent geophysical data to identify high-priority drill targets beneath volcanic cover near the main Linka Pit. Field programmes, including mapping and trench sampling, are scheduled to begin shortly to validate targets and provide immediate geological insights.
Permitting and Drilling Plans Progress
The company is preparing to submit a Notice of Intent (NOI) to the Bureau of Land Management for drilling approval. Approval is anticipated within the quarter to allow for immediate site access for drill rigs. Contractor engagement is underway, with a maiden drilling campaign expected to begin in the June quarter.
Baseline data collection and technical studies are also in progress to support future permitting requirements as the project advances. Moreover, field data collection has been initiated and will continue throughout the year.
Corporate Strategy and Market Positioning
The company is advancing initiatives to strengthen its liquidity and presence in the United States. Plans for a US over-the-counter listing are expected to broaden investor access and are expected to be completed by this quarter. Meanwhile, the company is finalising its application for membership in the Defense Industrial Base Consortium.
The company is also engaging with government stakeholders to position the Linka Project as a potential domestic source of tungsten amid increasing demand within the US supply chain.
Viking Mines’ latest update outlines a coordinated programme spanning technical development, field exploration, and corporate initiatives. With multiple activities progressing simultaneously, the Linka Project is moving toward its next phase of exploration and potential development in Nevada.Top of Form
