Guardian Metal Resources PLC reported exploration results and claim-staking activity across seven non-core Nevada projects prospective for tungsten, precious metals, base metals and lithium. The portfolio now includes newly staked White Elephant and Cinch and expanded Pilot North and Garfield, while flagship efforts remain on Pilot Mountain and Tempiute.
At White Elephant, 57 claims were staked and channel sampling at the Pyramid Zone returned 95 ft (29.0 m) at 0.31% WO3, including shorter higher-grade intervals. Pilot North mapping outlined over 4,000 ft of outcropping skarn, with channels including 95 ft at 0.18% WO3 and copper-silver-rich sections. Cinch grab samples yielded up to 0.22% WO3 and 1,950 g/t Ag, while Garfield was enlarged by 56 claims and produced rock chips up to 11.2 g/t Au and 310 g/t Ag, plus a 180 ft channel averaging 0.064 g/t Au that suggests bulk-tonnage style mineralisation. The board is assessing options to advance these non-core assets for shareholders while focusing resources on moving Pilot Mountain and Tempiute toward potential commercial production; all reported projects remain at an exploration stage and true thicknesses of intervals are not yet defined.
Guardian Metal Resources has signed a strategic partnership with the Montana Mining Association, working alongside Montana Technological University and the Army Research Laboratory, to run a U.S.-based tungsten mining and recovery pilot program focused on defense applications.
The company will supply approximately 250–400 tonnes of stockpiled legacy ore from its Tempiute Tungsten project in Nevada, to be transported to Philipsburg, Montana, for trial processing, with first shipments expected by late summer 2026, subject to ongoing metallurgical and pilot-scale test work. The program aims to upscale domestic tungsten-rich tailings and legacy ore into tungsten metal powder, supporting a fully domestic mine‑to‑market supply chain and reinforcing Guardian Metal’s strategy around its Tempiute and Pilot Mountain projects.

Guardian Metal Resources released a positive pre-feasibility study for its Pilot Mountain tungsten project in Nevada, outlining strong economics and a clear path toward potential development. At the base case tungsten price of US$197,300 per tonne of WO₃, the study indicates after-tax free cash flow of US$1.058 billion, an after-tax NPV₈ of US$660.3 million, and a post-tax IRR of 59.6% with a one-year capital payback from first commercial production.
The plan envisages initial capex of US$288.7 million for a 4,000 tonnes-per-day open-pit operation producing about 1,990 tonnes of WO₃ in concentrate per year over an initial eight-year mine life, totaling 15,916 tonnes of recovered WO₃. Probable reserves total 11.8 million tonnes grading 0.171% WO₃, containing 20,275 tonnes of WO₃ and 3.5 million ounces of silver.
At the 12 June 2026 tungsten spot price of US$304,000 per tonne, NPV₈ rises to US$1.366 billion and IRR to 101.6%, with modeled after-tax free cash flow of US$2.088 billion and a six-month payback. The project is supported by a prior US$6 million U.S. Department of War Defense Production Act investment and targets first ore through the mill in Q4 2028, subject to permitting, financing, and a future construction decision.

The PFS is led by Guardian Metal’s in-house team with Samuel Engineering and other specialists, and is supported by a $6.2m Defense Production Act Title III investment from the U.S. Department of War into its U.S. subsidiary. Following publication, the company will host a live investor presentation via 6ix on 01 July 2026 at 11:00 ET / 16:00 BST to discuss the Study and outline next steps for Pilot Mountain.
Guardian Metal recently listed on the NYSE American and is advancing two Nevada tungsten projects, Pilot Mountain and Tempiute, positioning itself as a strategic supplier of this critical defense and industrial metal, while cautioning that project development depends on regulatory approvals, technical results, and other risks described in its SEC filings.
