Viking Mines Ltd Achieves 16-Fold Tungsten Grade Upgrade Breakthrough

Viking Mines Achieves Breakthrough 16x Tungsten Grade Upgrade

Viking Mines Ltd has announced an exceptional metallurgical achievement that marks a significant milestone in the tungsten grade upgrade process. This breakthrough, characterised by a remarkable 16x improvement in tungsten grade, underlines the potential for a cost-effective, rapid development pathway in the critical tungsten market.

The initial gravity separation testwork at the Linka Pit has yielded outstanding results. Achieving a concentrate grade of 22.9% WO₃ from a feed of 1.4% WO₃ demonstrates the impressive capacity of a simple and efficient processing method. The use of gravity separation, a method known for both its simplicity and low operational costs, bolsters confidence in the project’s underlying economics.

Furthermore, with a recovery rate of 63.7%, this tungsten grade upgrade provides clear evidence of Viking Mines’ technical excellence. This success is a compelling example of how innovative metallurgical techniques can rapidly enhance the value of mineral assets.

Gravity Processing Delivers Outstanding Initial Results

The first-pass test results have exceeded expectations by demonstrating that gravity separation is not only cost-effective but also highly efficient. The method eliminates the complexities and expenses associated with chemical reagents, unlike other processes such as flotation.

Viking Mines recorded key performance metrics during testing:

• Feed Grade: 1.4% WO₃
• Concentrate Grade: 22.9% WO₃
• Grade Increase: 16x multiplication
• Recovery Rate: 63.7%
• Processing Method: Gravity separation

These impressive figures highlight the project’s potential in delivering a sustainable and scalable technology solution. The successful implementation of gravity processing underlines the economic merits of the tungsten grade upgrade, a process that is pivotal to achieving low-CAPEX development.

How Does Gravity Separation Work?

Gravity separation exploits the density differences between scheelite and waste rock. The process involves a physical separation that requires less chemical input and complex infrastructure. This method is ideal for tungsten extraction because it relies on simple mechanical means.

By focusing on this technique, Viking Mines avoids costly reagents and reduces both capital expenditure and operational costs. Such efficiency makes gravity separation one of the most attractive processing methods for critical metals in today’s competitive mining environment.

Optimisation Programme and Testwork Details

The optimisation programme evaluated three different grind sizes to determine the most effective combination of grade enhancement and recovery rate. The coarsest grind size of 200µm delivered the best performance, reaffirming the benefits of less aggressive processing.

Below is a table summarising the performance metrics for each grind size:

The table clearly demonstrates the advantage of using coarser grind sizes. With minimal waste interference, Viking’s approach positions the tungsten grade upgrade as both technically and economically superior.

Fast-Track Development Strategy and Next Steps

Viking Mines is leveraging these encouraging results as part of its fast-track development strategy. The company is committed to optimising the process further, with several immediate next steps lined up to enhance overall efficiency and recovery.

Immediate next steps include:

1. Cleaner Gravity Optimisation: Further testing with coarser grind sizes and staged grinding techniques.
2. Flotation Testwork: Processing gravity tails to maximise overall tungsten recovery.
3. Modular Equipment Evaluation: Engaging in partnership discussions with processing specialist Mineral Technologies.
4. Drill Planning: Preparing for a comprehensive drilling programme in the upcoming June quarter.

These steps are complemented by collaboration with reputable technical consultants, such as IMO and Base Met Labs, ensuring adherence to world-class metallurgical standards.

Market Timing and Strategic Significance

Global tungsten pricing remains near all-time highs, intensifying the strategic importance of Viking Mines’ achievements. Currently, ammonium paratungstate (APT) has reached US$1,850/mtu, reinforcing the value of a robust tungsten grade upgrade.

The timing of this breakthrough is particularly favourable due to tungsten’s classification as a critical mineral by the US government. Rapid technological advancements further enhance the outlook for Viking Mines, positioning the company to take advantage of both market price dynamics and increasing demand from various industrial sectors.

High market prices, combined with the advantages of gravity processing, create an ideal environment for accelerating development while minimising upfront costs. Investors are likely to see both technical and financial benefits from this strategic position.
