  • Viking Mines Advances Linka Tungsten Project with Premium 62.5% WO3 Concentrate
    May 28, 2026, 5:08 PM EDT. Viking Mines (ASX:VKA) announced a significant improvement in the Linka tungsten project in Nevada with metallurgical testwork yielding a premium 62.5% tungsten trioxide (WO3) concentrate at 59.8% recovery from a 1.2% feed grade. This marks a substantial increase from previous results of 56.4% WO3 at 46.0% recovery. The concentrate quality approaches Almonty's Sangdong mine in Korea and surpasses recent figures from Spain's Barruecopardo mine (53.2% recovery). Viking's step-change supports a low-cost "Rapid Start" development model emphasizing physical gravity separation over chemical processing, enabling faster project advancement. Validation tests on a larger 10kg sample scale de-risk the metallurgical flowsheet ahead of the planned maiden drilling campaign. Tungsten prices remain near all-time highs at around US$3,050 per metric tonne unit (mtu), bolstering the project's economic outlook.
