Viking Mines Achieves 16-Fold Tungsten Grade Increase at Nevada's Linka Project
Viking Mines has reported a 16-fold increase in tungsten grade at its Linka project in Nevada, following initial gravity separation tests. A sample with 1.4% tungsten trioxide yielded a concentrate of 22.9% with a recovery rate of 63.7% at a grind size of 200 microns. The Linka site features high-grade scheelite mineralization in a skarn system. Viking is exploring low-cost modular processing solutions and advancing geological modeling for further development.

Viking Mines initiated metallurgical tests at its Linka tungsten project in Nevada, achieving a 16-fold increase in tungsten grade through gravity separation. Tests on a sample with 1.4% tungsten trioxide produced a concentrate with 22.9% tungsten trioxide and a 63.7% recovery rate at a grind size of 200 microns.
The project is located in the Spencer Hot Springs Mining District, characterized by high-grade scheelite mineralization. Viking is assessing low-cost processing options and developing geological models while advancing federal permitting for drilling.
The broader Nevada tungsten portfolio has historically produced 123,000 tonnes of ore. Current tungsten prices are near record highs, driven by geopolitical factors and demand in various sectors.
