Guardian Metal Resources has entered a strategic processing partnership to evaluate the recovery of tungsten from legacy material at its Tempiute project in Nevada, with trials planned through a facility in Philipsburg, Montana.
The LSE- and NYSE American-listed Guardian Metal Resources closed Friday at approximately 184 pence per share, rising 0.82%, with a market capitalisation of around £358 million. The programme brings together the Montana Mining Association, Montana Technological University and the US Army Research Laboratory to assess tungsten recovery and processing routes for potential defence-related applications.
Tempiute Material to Undergo Pilot Processing
Under the partnership, Guardian expects to provide approximately 250–400 tonnes of legacy tungsten-bearing material from the Tempiute project in Nevada for trial processing at a facility located in Philipsburg, Montana. The work is designed to demonstrate the recovery and conversion of tungsten-bearing material into tungsten products suitable for defence applications. Initial shipments of material are expected in late summer 2026, following further metallurgical testing and pilot-scale processing activities.
Project Development Depends on Trial Results
The partnership increases the project’s relevance within US and allied critical minerals supply chain initiatives, but it does not represent a binding commercial offtake agreement or completion of an economic assessment. Future project valuation will depend on several technical and commercial factors, including tungsten recovery rates, product specifications, processing costs and evidence that the trial programme can be expanded into a commercially financed supply chain.
