Thor Mining PLC said Dec. 13 an updated resource for the Desert Scheelite deposit, part of its Pilot Mountain project in Nevada, raised the scheelite inventory by 6.5%.

The deposit now comprises 10.7 million tonnes at 0.26% tungsten trioxide, or WO3, 19.38 g/t silver, 0.15% copper and 0.38% zinc, at a cut-off of 0.15% WO3. It includes 27,700 tonnes of WO3, 85% of which is in the indicated category, 207 tonnes of contained silver, 16,000 tonnes of copper and 40,300 tonnes of zinc.

It is also the first time zinc has been included in the deposit resource. The company said the planned flotation recovery process is expected to recover zinc sulphides into concentrate at minimal additional cost.
