Almonty Industries (ALM) received certificates issued September 17 permitting ore processing at its Sangdong Mine in South Korea.
The certificates cover processing and crushing facilities and allow Almonty to sell the resulting tungsten concentrate. GoldHaven Resources (GHVNF) completed an extended drillhole at its Magno Project. Newly identified skarn intervals total approximately 145 metres of drill length; the estimated true thickness of approximately 40 to 45 metres is preliminary, and assays have not been reported.
Kennametal (KMT) reported fiscal fourth-quarter 2026 sales of $737 million, up 43% from the prior-year quarter. Fiscal 2026 sales rose 20% to $2.36 billion, while operating cash flow was negative. Guardian Metal Resources (GMTL) completed 41 Tempiute exploration holes and reported tungsten-rich zones beyond the historical mine footprint. Idaho Strategic Resources (IDR) reported a 32-metre Diamond Creek trench averaging approximately 1.8% total rare earth oxides.
Guardian Metal Resources (GMTL) reported positive drilling results from its Tempiute tungsten project in Nevada, including initial Phase II resource drilling assays and final Phase I regional exploration data.
Phase II aims for 46 diamond drillholes; 28 are complete and assays from the first four show broad mineralization, highlighted by hole TP26-046 with 27.9m @ 0.27% WO₃ from 68.6m and 92.0m @ 0.34% WO₃ from 102.5m, including 12.7m @ 0.53% WO₃. Phase I regional work saw 20 of 41 holes intersect strong tungsten, including TP25-021 with 32.4m @ 0.26% WO₃ and 1.7m @ 2.00% WO₃. On these results and visual mineralization in additional holes, the company will start rehabilitating historical underground workings in October 2026 to allow underground drilling. The project remains at the exploration stage with no Mineral Resource or Reserve yet defined and significant technical, permitting and financing risks disclosed.
Guardian Metal Resources (GMTL) filed its Annual Report on Form 20-F for the year ended 30 June 2026 with the U.S. Securities and Exchange Commission on 17 September 2026.

Guardian Metal is a strategic mineral exploration company focused on advancing the Pilot Mountain and Tempiute tungsten projects in Nevada. In July 2025, the U.S. Department of War invested US$6.2 million in its U.S. subsidiary to support the Pilot Mountain PFS, and the company completed a NYSE American listing on 20 March 2026.
Guardian Metal Resources (GMTL) reported audited results for the year ended 30 June 2026 and detailed major progress at its Nevada tungsten projects.
The Group received a US$6.2 million U.S. Department of War investment under DPA Title III to fund the Pilot Mountain Pre-Feasibility Study (PFS) and project advancement. The completed PFS shows after-tax NPV of US$660.3 million, IRR of 59.6%, forecast after-tax free cash flow of US$1.058 billion over an initial eight-year mine life and a payback period of about one year, using a base case tungsten price of US$197,300/t WO₃. An upgraded S-K 1300 Mineral Resource Estimate led to conversion of 97% of Indicated Resources into Probable Reserves of 11.8Mt. The company raised total equity of US$89.3 million, including an upsized NYSE American IPO with gross proceeds of about US$68.3 million, and expanded its Tempiute footprint, acquiring 841 acres of property and 2,540 acre-feet of annual water rights and advancing drilling.
GoldHaven Resources (GHVNF), Almonty Industries (ALM), Guardian Metal Resources (GMTL), Ramaco Resources (METC) and Idaho Strategic Resources (IDR) are highlighted as tungsten- and critical-minerals‑exposed names amid tightened Chinese export controls and looming U.S. defense‑procurement rules.
Tungsten concentrate prices have risen from $750–$850 to $2,500–$2,800 per mtu since early 2026 after China limited 2026–2027 exports to 15 firms. From January 1, 2027, DFARS 252.225‑7052 will restrict tungsten at the mine/ore stage, including scrap, shrinking compliant supply options.
GoldHaven reports over 800 m drilled at its Magno Project’s Kuhn skarn, with broad skarn intervals and down‑dip extensions but no assays yet, and only historical, non‑current estimates. Almonty signed a binding Rwanda joint venture and recently extended its Sangdong offtake by 6 years and 40% in volume. Guardian is set to join the FTSE AIM 50, supported by a prior US$6.2 million U.S. Department of War investment in Pilot Mountain, while Ramaco and Idaho Strategic advance unconventional and early‑stage U.S. critical‑minerals projects.
Guardian Metal Resources (GMTL) reported tungsten drilling results from the Tremor and Good Hope zones at its 100%-owned Pilot Mountain project in Nevada, indicating potential to expand mineralization beyond the current Pre-Feasibility Study mineral resources.
At the Tremor Zone (north), mineralization has been confirmed over about 200m strike and 190m dip, remaining open in multiple directions. Notable intercepts include PM26-088 with 64.15m @ 0.20% WO3 from 139.97m, including 14.27m @ 0.34% WO3, and PM26-097 with several zones up to 44.08m @ 0.18% WO3. At the near-surface Good Hope Zone, within 1.1–1.3km of existing resource areas, drilling returned GH26-01 with 12.95m @ 0.79% WO3 from 12.19m and GH26-02 with 13.11m @ 0.42% WO3 from 2.13m, together representing 23m apparent thickness averaging 0.58% WO3.
Relocation of the planned tailings storage facility is required but is not expected to materially affect project costs or timelines. No mineral resource estimates have yet been prepared for Tremor or Good Hope.
Guardian Metal Resources (GMTL) signed a collaboration agreement with forensic origin verification firm Oritain Global to build an inaugural database of tungsten origin fingerprints covering its Tempiute and Pilot Mountain projects.
The database is intended to enable scientific provenance verification of tungsten for governments, industry and end consumers, supporting tighter traceability requirements expected from January 1, 2027 under Section 854 of the FY2024 NDAA and related DFARS rules. Executive Order 14415, signed July 20, 2026, further restricts sourcing waivers and mandates full supply chain mapping, making verified U.S.-origin tungsten increasingly important for defense procurement. Guardian Metal will supply initial tungsten samples from both Nevada projects, positioning the company to align its domestically sourced tungsten with evolving U.S. critical mineral and defense supply chain priorities.
Guardian Metal Resources (GMTL) will join the FTSE AIM 50 Index on 21 September 2026.
The inclusion follows FTSE Russell’s quarterly review of the FTSE AIM UK 50, FTSE AIM 100 and FTSE AIM All-Share indices. Guardian Metal is a strategic mineral exploration and development company focused on tungsten projects in Nevada, USA, aiming to reshore mined tungsten production to the United States.
In July 2025, the U.S. Department of War invested US$6.2 million in the company’s U.S. subsidiary under Title III of the Defense Production Act to support the Pilot Mountain PFS, and the company completed a NYSE American listing on 20 March 2026.
Western Star Resources (WSRIF) has begun a high-resolution drone magnetic survey at its 100%-owned Eagle Point tungsten project in Hidalgo County, New Mexico, as part of a broader push to delineate domestic tungsten resources amid tightening Chinese export controls and rising defense demand.
The UAV survey covers the property at 25–50 metre line spacing, aiming to map the limestone–granite contact and magnetite-bearing tactite bodies that host scheelite mineralisation, including beneath cover, and to extend eight historically known skarn bodies along strike. Data collection is expected to finish in about three weeks, with processing and interpretation to follow, feeding into geological mapping, sampling, drill targeting and permitting ahead of a planned maiden drill program in 2026.
The commentary also profiles sector players Almonty Industries (ALM), Guardian Metal Resources (GMTL), American Tungsten (TUNGF) and Vault Strategic Mining (KNXFF) as context for the emerging US-focused tungsten supply chain.
