The PFS results are a major de-risking catalyst for GMTL, validating the project's economics and strategic importance for U.S. tungsten supply. Traders should watch for the upcoming investor presentation on 1 July 2026, the filing of the S-K 1300 Technical Report Summary, and progress on the Mine Plan of Operations and NEPA permitting as key near-term catalysts. The company may also make an early construction decision based on the PFS, which would be a significant positive catalyst.

Executive Summary
Guardian Metal Resources PLC announced the results of a Pre-Feasibility Study (PFS) for its Pilot Mountain tungsten project in Nevada, demonstrating robust economics with an after-tax NPV8 of US$660.3 million and an IRR of 59.6% at base case pricing. The PFS, completed by independent firms under S-K 1300 standards, outlines an 8-year mine life with first production targeted for Q4 2028 and positions Pilot Mountain as a potential first new U.S. tungsten mine in over a decade, supported by a U.S. Department of War DPA Title III investment.
Key Facts
- After-tax NPV8 of US$660.3 million and IRR of 59.6% at base case tungsten price of US$197,300/t WO3.
- After-tax free cash flow of US$1.058 billion with a capital payback period of 1 year at base case.
- Initial capital expenditure of US$288.7 million, including 15.7% contingency.
- Probable Mineral Reserves of 20,275 tonnes WO3 (11.8 million tonnes @ 0.171% WO3).
- First production targeted for Q4 2028, subject to permitting and a construction decision.
- PFS was funded in part by a US$6.2M U.S. Department of War Defense Production Act Title III investment in July 2025.
- At the 12 June 2026 tungsten spot price of US$304,000/t, after-tax NPV8 rises to US$1.366 billion and IRR to 101.6%.
Financial Impact
After-tax NPV8 of US$660.3M at base case, rising to US$1.366B at spot tungsten prices; after-tax free cash flow of US$1.058B at base case.
Risk Factors
- Project development is subject to permitting, financing, and a final construction decision; no assurance of timeline or economic outcomes.
- Sensitivity to tungsten prices: a 20% decline from base case reduces after-tax NPV8 to US$395M and IRR to 41.3%.
- Execution risk: initial capex of US$288.7M must be financed; the company may proceed without a full feasibility study, increasing technical risk.
- Reliance on U.S. government support and geopolitical factors; China's export controls on tungsten create both opportunity and dependency risk.
