• Achieved 76.0% tungsten recovery from a 1.2% feed grade
• 56.9% WO3 concentrate grade achieved
• Represents a 1.27x improvement from previous results
• Testwork continues to derisk process flowsheet
• Maiden drilling program to commence in June 2026 quarter

Viking Mines Ltd is pleased to announce significant advancements in metallurgical testwork at the Linka Tungsten Project in Nevada, USA. The combined gravity and cleaner flotation circuit testwork has achieved a 76.0% tungsten recovery from a 1.2% feed grade, with a 56.9% WO3 concentrate grade. This represents a 1.27x improvement from the previously reported 59.8% recovery. The testwork continues to derisk the process flowsheet, with ongoing efforts to optimize flotation conditions and achieve further improvements. The maiden drilling program is scheduled to commence in the June 2026 quarter. The results feed directly into the conceptual processing study underway with Mineral Technologies, which will provide initial capital and operating cost estimates. With global tungsten prices at high levels, the ability to produce high-grade concentrates via a low-CAPEX model positions Linka as a strategic asset.

Viking Mines plans to continue optimizing the flotation circuit to target >80% recovery and >50% WO3 grade. The maiden drilling program is set to commence in the June 2026 quarter, with ongoing testwork to refine CAPEX estimates and plant design.
