Viking Mines Ltd. has completed gravity separation testwork on three additional metallurgical samples from its Linka tungsten project in Nevada, US, delivering consistently high-grade concentrate results.
The latest program evaluated samples from the Linka Stockpile, Hillside, and Conquest locations, bringing the total number of tested samples at the project to four. All four samples successfully produced gravity concentrates grading above the target threshold of 50 per cent tungsten trioxide.
Notably, the Conquest sample generated a concentrate grading 69.3 per cent tungsten trioxide with a 43.8 per cent recovery rate. This outcome outperformed earlier testwork on the Linka Pit sample, despite Conquest representing the lowest head grade evaluated to date at 0.76 per cent tungsten trioxide.
The Linka Stockpile sample achieved the highest gravity recovery of the group at 46.8 per cent, returning a concentrate grade of 55.8 per cent tungsten trioxide.
Meanwhile, the Hillside sample delivered a 53.9 per cent tungsten trioxide concentrate at a 42.5 per cent recovery rate.
Viking Mines CEO Julian Woodcock said: “The key takeaway from these results is that the gravity separation is proving repeatable across additional samples when compared to our prior testwork.
“Significantly, the Conquest sample delivered a higher grade and recovery product than the original May 2026 Linka Pit test result… from the lowest-grade sample we have tested to date.
“With global tungsten concentrate pricing commanding a significant US$244,000 per tonne tungsten trioxide, the Linka concentrates are proving to be a very high value product.”
Flotation testwork on the remaining gravity tails is currently ongoing to further boost overall metal recoveries. Initial combined gravity and flotation testing on the Linka Stockpile sample raised total recovery to 73.1 per cent.
The company continues to advance the Nevada portfolio of tungsten projects on multiple fronts.
Viking plans to resume drilling at Linka in mid-October, alongside advancing ore sorting testwork in Germany and processing pending laboratory assays for 13 exploration holes.
