Highlights
- Viking Mines has completed its second field campaign at the Linka Tungsten Project.
- 98 samples have been collected across the campaign.
- Visual scheelite mineralisation was identified under UV light in additional stockpiles near the historic Conquest mine.
- The newly discovered surface stockpiles could potentially provide low-cost feed material for future processing without requiring drilling or mining activities.
- A 63-hole maiden drilling campaign remains on schedule for late June 2026.
- Ore sorting testwork has commenced at TOMRA in Germany to evaluate whether tungsten mineralisation can be efficiently separated from waste rock.
Viking Mines Limited (ASX:VKA) has completed its second field mapping and sampling campaign at the Linka Tungsten Project in Nevada, USA, identifying additional mineralised stockpiles. The campaign focused on the historic Linka (Main), Conquest and Hillside mining areas, with samples collected for geological mapping, outcrop sampling, trench resampling and stockpile investigations aimed at expanding the company’s understanding of tungsten mineralisation across the project.
Additional Stockpiles Reveal Visible Mineralisation
A key outcome of the campaign was the identification of visual tactite mineralisation containing scheelite under UV light within two historical stockpiles located near the historic Conquest mine. The stockpiles contain a combination of mineralised material and waste rock, creating potential suitability for ore sorting techniques.
The company noted that, subject to assay confirmation, the newly identified stockpiles could provide additional feed material if the Linka Project advances toward development, because the material is already located at surface, it may not require drilling, blasting or mining activities prior to processing.
During the campaign, the company collected 98 samples across the project area for trench resampling, outcrop sampling, stockpile investigations and geological mapping activities. Six historical trenches were also mapped and resampled, with visible mineralisation observed under UV light in each trench location.
Ore Sorting Testwork Underway in Germany
The company has confirmed that samples collected from the Linka (Main) Stockpile during an earlier campaign have now been delivered to TOMRA in Germany. The program is designed to assess whether ore sorting can effectively separate mineralised material from waste rock.
If successful, the same processing technique could potentially be applied to the newly identified Conquest stockpiles.
The broader field campaign also included geological mapping across the claim package, aimed at improving understanding of surface cover throughout the project area.
Geological Mapping Supports Drilling Plans
Geological mapping confirmed the presence of alluvial cover and un-mineralised tuff west of the outcropping Linka Mineralised Trend. These findings support the scout drilling approach planned for those target areas as part of the company’s maiden drilling campaign.
The maiden drilling program is scheduled to commence in late June 2026 and will consist of 63 planned drill holes.
In parallel, the company is awaiting assay results from both field campaigns. Results from the first campaign, including sampling from the Linka Main stockpile and tailings dam, are expected in June 2026, while assays from the second campaign are anticipated in July 2026.
Additional metallurgical updates on gravity concentration and flotation cleaning testwork are in progress, alongside conceptual processing studies aimed at assessing potential processing costs, development timelines and project design parameters.
