Viking Mines (ASX:VKA) advances Linka Tungsten Project with field programme and Metallurgical testing

Viking Mines has launched a multi-faceted field programme at its Linka Tungsten Project in Nevada, USA.

The field team has mobilised to the site to evaluate the historical ore stockpiles and tailings dam, with the aim of assessing the potential for reprocessing these materials as a low-cost feedstock for future plant operations.

This work comes at a time when global tungsten prices have reached 90-year highs, further highlighting the strategic value of the Linka Tungsten Project.

Highlights:

• Field team mobilised to evaluate historical tailings and ore stockpiles.
• Systematic sampling underway to assess grade and volume of historical tailings for potential reprocessing.
• Sampling of historical ore stockpiles to confirm grade consistency, building on previous assay results of 0.8% WO3.
• Metallurgical testing continues, with recent success producing a 63.6% WO3 concentrate from primary mineralisation.
• Additional metallurgical sample collection for comminution testing to refine operational expenditure (OPEX) data.
• Initial field investigations underway to validate 3D geological models and geophysical targets, including a mineralised corridor and extensions under cover.

The Linka Tungsten Project is located in Nevada, a region known for its mining potential.

Viking Mines’ focus is on advancing the project with a systematic approach to resource evaluation, beginning with the assessment of historical tailings and stockpiles, which could potentially provide a low-cost source of feedstock.

The field programme will assess the grade and volume of these materials, with the goal of evaluating their suitability for reprocessing, and the results will be crucial in determining the viability of supplementing the future plant’s feedstock with these resources.

Viking Mines Managing Director and CEO, Julian Woodcock, commented,

“Viking has commenced a period of high activity, transitioning from analysis into active project development. Our workstreams target a rapid, low-CAPEX pathway to production. With tungsten at 90-year highs, the strategic value of our Nevada assets is clear, and we look forward to providing updates as milestones are achieved.”

Alongside the surface evaluations, Viking Mines continues to progress its metallurgical testing, having already achieved a 53-fold upgrade to produce a premium 63.6% WO3 concentrate from the primary mineralisation, a promising result that supports the long-term development of the project.

Further testing is focused on obtaining additional data on comminution, which will inform the OPEX and ensure the scalability of a modular plant.

In addition to surface activities, Viking Mines is conducting ground-truthing to validate its 3D geological model and geophysical targets.

The mineralised corridor, which extends 820m and includes an 800m extension under volcanic cover, is being carefully assessed as part of the exploration programme, with the work aimed at confirming the presence of garnetite skarn signatures ahead of subsurface testing.

The Linka Tungsten Project is progressing well towards the next stages of development, with ongoing field work and metallurgical test results positioning Viking Mines for a rapid, low-CAPEX pathway to production.

The results from the surface evaluations and the upcoming drilling campaign, scheduled for the June Quarter, will provide further insights into the project’s commercial potential.

As tungsten prices remain elevated, Viking Mines is well-placed to advance the Linka Tungsten Project into its next phase.
