    US Antimony’s Fostung tungsten resource: project economics and mine design lens

    US Antimony’s Fostung tungsten resource: project economics and mine design lens

    First reported on MINING.com

    30 Second Briefing

    US Antimony has reported an SRK Consulting–prepared inferred resource of 14.62 million tonnes at 0.17% WO₃ (53.6 million lb contained) at its Fostung tungsten project, 70 km west of Sudbury, replacing a previous 12.4 million tonnes at 0.213% estimate. The company plans an initial open-pit operation leveraging existing infrastructure, followed by underground mining, and has applied for US Defense Production Act Title III funding to accelerate development. If built, Fostung could be the first tungsten ore source in the US or Canada since 2016, in a market where WO₃ prices have nearly tripled to about $1,890/t.

    Technical Brief

    • At US$1,890/t WO₃, in-situ metal value is estimated at ~US$4.6 billion before costs.
    • Development concept is staged: initial open pit using existing regional infrastructure, then transition to underground mining.
    • Next work programme prioritises step-out drilling, bulk sampling and metallurgical testwork to upgrade resource confidence.
    • US Antimony operates a Montana smelter rated at 5 million lb antimony per year, giving downstream processing experience.
    • China currently controls roughly 80–85% of global tungsten processing capacity, framing Fostung’s strategic positioning.

    Our Take

    With WO3 compound prices having tripled over the past year and China controlling roughly 80–85% of global tungsten processing capacity, a Canadian asset like Fostung in Ontario gives United States Antimony leverage in North American critical minerals policy discussions, especially around supply chain security.

    The inferred 53.6 million lb WO3 at the Fostung deposit, acquired for US$5 million plus a 0.5% royalty, implies a very low in‑situ cost of entry compared with other critical‑mineral M&A in our database, which may support future financing narratives even if the grade is modest.

    Other tungsten‑tagged pieces in our coverage, such as the Blue Moon Metals acquisition of the Apex gallium‑germanium mine in Utah, indicate that junior and mid‑tier players are increasingly using low‑cost acquisitions of past or non‑core assets to assemble critical‑mineral portfolios rather than greenfield exploration alone.

    MetalQuest’s Lac Otelnuk iron project: economics and infrastructure lens for engineers

    MetalQuest Mining’s Lac Otelnuk project in northern Quebec hosts 4.9 billion tonnes of proven and probable reserves grading 28.7% Fe, with a 2015 feasibility study outlining an 11.6 km by 2.8 km open pit, post-tax NPV of US$5.24 billion (8% discount), IRR of 13% and capital costs of about US$14.2 billion. The study forecasts 68.5% Fe concentrate with 0.02% P and 2.95% SiO₂, positioning it for DRI-based low-emission steelmaking using Quebec hydro power. Infrastructure remains the critical constraint, with a previously proposed 755 km concentrate slurry pipeline to Sept-Îles now likely to be replaced by road and rail, and MetalQuest seeking a major partner ahead of a new feasibility targeted for 2030.

    XCMG–Codelco MoU: haul fleet competition and design notes for Andean copper mines

    XCMG has signed a memorandum of understanding with Chilean copper major Codelco in Santiago on 3 March, following Codelco Chairman Máximo Pacheco’s visit to XCMG’s Xuzhou manufacturing base in February. The agreement, signed by XCMG Vice President Liu Jiansen and Codelco Chief Procurement Officer Mauricio Acuña, centres on expanding supply of large-scale mining equipment and support services to Codelco’s open-pit and underground copper operations. For engineers, the deal signals intensifying competition with established OEMs on haul trucks, loaders and drilling fleets in high-altitude Andean conditions.

    Oklahoma critical minerals refining push: infrastructure and power notes for engineers

    Oklahoma is positioning itself as a critical minerals processing hub rather than a mining state, anchored by Emirates Global Aluminium’s proposed US$4 billion primary aluminium smelter at the Port of Inola on the McClellan–Kerr Arkansas River system and backed by surplus low‑cost power from wind and natural gas. USA Rare Earth is building a vertically integrated rare earth magnet plant in Stillwater with about US$1.6 billion in public and private funding, while Stardust Power (NASDAQ: SDST) is advancing a lithium refinery in Muskogee with Sumitomo offtake and key permits secured. The cluster targets defence and aerospace demand around Tinker Air Force Base and other installations, aiming to plug the “missing middle” between raw mineral supply and finished components.
