China Controls Tungsten Supply as Western Drill Programs Expand

Tungsten concentrate prices outside China rose from $750-$850 per metric tonne unit at the start of 2026 to $2,500-$2,800 by late May, highlighting acute supply pressure as China produced about 67,000 of 85,000 tonnes mined globally in 2025. New U.S. defense sourcing restrictions effective January 1, 2027 and Canadian exploration-tax-credit eligibility support Western tungsten development. GoldHaven reported 145 metres of visually identified new skarn intervals at its Magno project, with preliminary true thickness of 40-45 metres, but no assays, resource estimate, or evidence of economic grades has yet been established.

Analysis

The investable read-through is not broad “critical minerals” beta; it is a widening Western tungsten procurement premium. ALM is best positioned because converted concentrate output and customer qualification can monetize scarcity materially sooner than an explorer can establish a resource. The key second-order beneficiary is KMT: its demonstrated ability to pass through input costs suggests a pricing umbrella for specialized tooling, but working-capital absorption means earnings strength can overstate near-term free-cash-flow conversion while raw-material prices rise.

The January 2027 procurement cutoff creates a 3-6 month customer-stockpiling and qualification window, potentially pulling forward demand for non-restricted units. This favors ALM and, at an earlier stage with substantially higher execution risk, GMTL; it disadvantages Western industrial buyers without contracted supply and could ultimately encourage substitution, recycling, and tool-life optimization rather than perpetual spot-price elasticity. SAND has indirect exposure through Wolfram Bergbau, but tungsten is unlikely to be financially material enough to drive the parent’s valuation.

Do not underwrite the promotional exploration narrative around GOH: visual mineralization, unassayed intercepts, uncertain geometry, and likely financing needs make it a liquidity/event trade rather than a commodity exposure. The more contrarian issue for listed producers is that scarcity is already reflected in the non-China price spike; any evidence that defense demand is being met through inventories, recycled feed, or exemptions could compress the premium before new mine supply arrives. Over 6-18 months, successful ramp-up at Sangdong is the cleanest test of whether Western scarcity converts into durable EBITDA rather than merely higher spot quotes.

Immediate focus is ALM operational de-risking and first commercial shipments; over 1-3 months, watch contract pricing, payable terms, and customer concentration. Thesis failure would be a delayed/ramp-constrained Sangdong plant, lower realized concentrate pricing versus external benchmarks, or KMT inventory days and operating cash flow failing to normalize despite stable input prices. For GMTL, a resource-quality or permitting setback matters more than tungsten price direction.

Key Decisions for Investors

• Initiate/maintain an overweight long ALM on operational pullbacks, sized for commissioning risk; target a 6-12 month catalyst path around sustained commercial shipments and disclosed realized pricing. Risk/reward is attractive only if shipment volumes confirm ramp execution; exit/reduce on a material production delay or if realized pricing disconnects from Western concentrate benchmarks.
• Use a 1-3 month pair: long ALM / short KMT in equal dollar beta-adjusted size if tungsten input costs remain elevated. ALM has direct scarcity torque, while KMT faces working-capital drag and eventual pass-through resistance; stop out if KMT reports accelerating organic volumes with positive operating cash flow or ALM reports ramp issues.
• Treat GMTL as a small, high-volatility watch-list position rather than core exposure pending resource-drilling results and a credible financing/permitting timetable. Add only after independently reportable resource economics support Pilot Mountain/Tempiute value; a 50%+ drawdown remains plausible if results fail to convert historical potential into mineable grade.
• Avoid GOH/GHVNF until assays, metallurgical recoveries, ownership/royalty terms, and a fully funded drill-to-resource budget are available. The disclosed promotional conflict makes any near-term price strength unreliable and raises dilution/liquidity risk.
• Monitor KMT quarterly for inventory growth, supplier prepayments, gross-margin resilience, and cash conversion. A reversal from inventory build to cash release would remove the strongest near-term short-side argument; continued cash burn despite pricing would support underweighting.
