〔Overnight Brief〕Copper Crashes 3% to $6.29/lb on COMEX and LME 3-Month Under $14,000 While US War Department Commits $450M to Tungsten and DOE Funds Four Mine-of-Future Sites - Cyclical Liquidation vs Strategic-Metals Securitization

0. Overnight Arc

Two markets in one board. Cyclical base metals liquidated - COMEX copper -3% to $6.29/lb (lowest since July 29), LME three-month through $14,000/ton at -1.8%, and the SHFE night session heavy in reds (silver -3%, tin and gold -2%+, glass -2%, zinc and soda ash near -2%, international copper -1%) ^[1][2][3][4]. Yet the strategic-metals track accelerated: antimony +18.11% from early August at 105,100 yuan/ton, germanium +11.63% at 19,200 yuan/kg ^[5]; the US War Department committed $450M to tungsten producer Elmet Group (ELMT spiked ~55% intraday to $25.03) ^[6]; DOE funded four Mine-of-Future test sites at $73M ^[7]; and Latrobe Magnesium signed an LOI for a 50,000 ton/year US magnesium project at $1.1-1.5B ^[8]. The mechanism: cyclical liquidations and supply-chain securitization are now decoupled.

1. Strategic Minor Metals Re-Rate

• **[NEW] Antimony:** 105,100 yuan/ton, +18.11% from early August 2026 ^[5].
• **[NEW] Germanium ingot (≥50Ω·cm):** 19,200 yuan/kg, +11.63% from early August ^[5].
• **[ONGOING] Bismuth, tantalum:** also firmer since August, no precise figures ^[5].
• **[NEW] Mechanism (People's Finance):** AI compute demand + rigid supply + export controls + strategic stockpiling = re-rating from "cyclical resource" to "strategic asset" ^[5].

2. US Industrial Policy Push

• **[NEW] War Department → Elmet Group (ELMT.US):** $450M via redeemable preferred stock, warrants for up to 19.9% of common, one independent director seat and one non-voting observer; $165M+ earmarked for Maine, Michigan, and Ohio facilities producing tungsten, molybdenum, and advanced materials, plus mining/processing in Australia and Spain. Stock +55% intraday to $25.03, an April-IPO high ^[6].
• **[NEW] Latrobe Magnesium:** LOI for a 50,000 ton/year primary magnesium plant in the US; 32,000 ton/year committed demand from US customers and traders; preliminary economic assessment complete; project cost $1.1-1.5B ^[8].
• **[NEW] DOE "Mine of Future":** $73M to four domestic mining-tech test sites via the Office of Critical Minerals & Energy Innovation (CMEI) and the Advanced Mining & Mineral Processing Technologies Office. Energy Secretary Chris Wright: "lab to deployment"; Deputy Secretary Audrey Robertson: "world-class test sites" ^[7].

3. Africa Resource Map

• **[NEW] DRC tiered geological data:** national geological data center under construction, $180M mapping contract with Spain's Xcalibur signed in January, plan runs through end-2026 under SGNC head Raoul Wazenga Vitima; DRC is the #1 cobalt and #2 copper producer globally - analysts flagged the policy could rival the cobalt-market reshape ^[9].
• **[NEW] Makoko copper (Ivanhoe Mines, DRC):** ~12 Mt of contained copper, +30% vs. 2025 estimate; indicated 42 Mt at 2.66% Cu, inferred 612 Mt at 1.8% Cu; called the largest, highest-grade copper discovery of the past 10 years; PEA targeted Q1 2027, site prep underway ^[10].
• **[NEW] Guinea ↔ Glencore:** Mines Minister Bouna Sylla confirmed post-bauxite-deal talks on alumina refining and energy investment; the prior week Nimba Mining + Glencore signed $300M+ in bauxite pre-financing and offtake for 10-12 Mt/yr over five years; Guinea overtook Australia as the world's largest bauxite producer in 2023 and started Simandou iron-ore exports in 2025 ^[11][12].

4. Contradictions and What Falsifies Next

• **Copper -3% on a day Makoko resource grew 30% and the US War Department closed a $450M tungsten bet** ^[6][1][10] - the long-run scarcity narrative is intact, but the short-run tape is selling.
• **Lithium carbonate halved to ~130,000 yuan/ton from 210,000** despite reported de-inventorying - "hidden supply" is the live question; the inventory claim rests on a single headline item, source quality is thin ^[13].
• **Alumina under "continuous oversupply pressure" with divided market intent** ^[14] even as Guinea and Glencore discuss new alumina refining investment - a real supply-demand test once those capacity talks firm up ^[11][12].
• **Falsifiable test:** Asia's Monday reopen and whether LME copper holds the $14,000 handle ^[2]; the DRC geological-data policy rollout through end-2026 is the longer-cycle swing factor ^[9].
