Tungsten Mining (ASX:TGN) completed an updated mineral resource estimate (MRE) for its Watershed tungsten project in Queensland, reporting at a reduced cut-off grade of 0.04% tungsten trioxide, revised downward from 0.05% to reflect the stronger global tungsten price environment, according to a Thursday Australian bourse filing.

The company said the lower cut-off grade better represents the economic potential of the deposit under current market conditions, with total measured, indicated, and inferred resources of 69.7 million tonnes at 0.109% tungsten trioxide for 76,000 tonnes of contained tungsten trioxide, increasing contained metal content by 8% from the prior MRE.
