Guardian Metal Resources PLC filings document U.S. foreign-issuer current reports for a Nevada-focused tungsten exploration company. The company's Form 6-K reports furnish press releases and exhibits covering Pilot Mountain pre-feasibility activity, total voting rights, option exercises, major-holdings notifications, and governance changes.
The filing record also describes the company's public-company structure, including ordinary-share capital, American Depositary Shares, FCA Disclosure and Transparency Rules notices, and ownership thresholds reported through TR-1 major-holdings notifications. These disclosures connect project-level mining updates with capital-structure and shareholder-reporting information for the issuer.
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 purchase, completed through a wholly owned U.S. subsidiary, totals US$1.3 million in cash. Management describes the deal as a key step in de-risking and advancing Tempiute by combining newly acquired water and land rights with existing site infrastructure to support future exploration and potential redevelopment.
