Viking Mines Achieves 76% Tungsten Recovery at Nevada Linka Project
Viking Mines reported 76% tungsten recovery and 56.9% tungsten oxide concentrate in metallurgical testwork at its Linka project in Nevada, exceeding the company's production targets. The result represents a 27% improvement from previous testing two weeks earlier and uses simple gravity and flotation processing technologies. The achievement is strategically significant as the United States seeks to reduce its near-total reliance on imported tungsten amid record-high commodity prices.
Viking Mines has achieved a major milestone in developing its Linka tungsten project in Nevada, delivering 76% recovery rates and producing a high-grade 56.9% tungsten oxide concentrate through metallurgical testwork. The result surpasses the company's target of greater than 70% recovery and concentrate grades above 50% tungsten oxide, representing a 27% improvement from testing conducted two weeks prior. The processing flowsheet combines proven gravity concentration (producing 66.6% tungsten oxide) with flotation concentration (48.2% tungsten oxide) to create the final blended product. Viking is pursuing a two-track development strategy: a maiden 63-hole drill campaign—the first drilling at the historic site in over 40 years—to define a new resource, and potential early processing of historical surface stockpiles that have assayed up to 1.1% tungsten oxide. The project's timing aligns with elevated tungsten prices, which have reached record levels above US$3,000 per metric tonne unit, and U.S. government efforts to secure non-China-dependent tungsten supply chains.
