About Mactung Project
A 2023 Technical Report announced updated mineral resources for Mactung. The mineral resource totaled 41.5 Mt Indicated Resource at 0.73% WO3and 12.2 Mt Inferred Resource at 0.59% WO3. It is estimated that there is the potential for an Exploration Target at Mactung of between 2.5 and 3.5 Mt at a grade of between 0.4 and 0.6% WO3in addition to the current Mineral Resources disclosed (see Fireweed news release). These results make it the world’s largest high-grade tungsten deposit.*
