〔Overnight Brief〕Copper Adds $190/t, Nickel $285/t and Zinc 2.00% Intraday—Lead Slips $4/t

0. Overnight Arc

• **[NEW] Overnight arc:** Cailian Press reported that LME copper, aluminum, zinc, nickel, tin and cobalt all closed higher, led by tin's $786/t gain and nickel's $285/t gain; lead alone fell, by $4/t ^[1].
• **[NEW] China follow-through:** International copper rose 0.82%; Shanghai copper gained 0.73%, aluminum 0.26%, zinc 0.90%, nickel 1.23% and tin 1.20%; Shanghai lead fell 0.99%, while stainless steel gained 2.78% ^[2].
• **[NEW] Cross-asset tension:** Jin10's night-open snapshot showed SC crude oil, fuel oil and low-sulfur fuel oil down more than 3%, bottle flakes nearly 3%, and paraxylene, asphalt, LPG and PTA more than 2%, while Shanghai silver rose more than 1% ^[3].
• **[NEW] Source quality:** Price reports are timestamped, but SMM's aluminum-processing-fee and copper-recycling entries provide only headlines, while the ITA PT Timah excerpt is truncated and accompanied by a registration prompt ^[1][4][5][6].

1. Tape and Cross-Market Read

• **[NEW] LME closing levels:** Copper finished at $14,345/t, up $190/t; aluminum at $3,094/t, up $25/t; zinc at $3,892/t, up $50/t; lead at $1,906/t, down $4/t; nickel at $15,556/t, up $285/t; tin at $49,659/t, up $786/t; and cobalt at $33,525/t, up $15/t ^[1].
• **[NEW] Zinc timestamp:** Jin10's earlier intraday report showed zinc at $3,903/t, up 2.00%; the later close was $3,892/t, up $50/t, so the two timestamped marks should not be treated as the same observation ^[1][7].
• **[ONGOING] Shanghai-night breadth:** Alumina gained 0.61%, aluminum alloy rose 0.57% and stainless steel advanced 2.78%, extending the stronger nonferrous tone even as Shanghai lead declined 0.99% ^[2].
• **[NEW] Causal limit:** The packet records the metals moves but provides no named driver for the rally, so the overnight evidence supports a price move rather than an attributed cause ^[1][2][7].

2. Supply, Demand and Corporate Signals

• **[NEW] Guinea bauxite:** Guinea's government said third-quarter bauxite exports rose 34% year over year to 50.10 million tonnes ^[8].
• **[NEW] PT Timah tin:** Indonesian state-owned producer PT Timah, listed as IDX: TINS, reported Q3 refined tin output of 5,325 tonnes, unchanged from the previous quarter, alongside record net profit for the first nine months; ITA estimated PT Timah accounted for 37% of domestic refined tin production, down from 90% in Q2, when a relicensing period heavily disrupted output across the wider industry ^[4].
• **[NEW] Ansteel procurement:** Ansteel opened a self-funded negotiation procurement for nickel-pellet alloy, with delivery scheduled for December 20, 2026 in Chaoyang, Liaoning ^[9].
• **[NEW] Aluminum conversion fees:** SMM's forward aluminum sheet-and-strip outlook said processing fees for popular products were stable to firm, but the packet contains no fee values or forecast period ^[5].
• **[ONGOING] Strategic-minerals cooperation:** Hubei Provincial Party Secretary Guan Zhiou met China Mineral Resources Group Chairman Yao Lin in Wuhan and called for greater deployment in Hubei across strategic-mineral exploration, mining, processing, trade and commodity logistics; Yao said the group would deepen cooperation with Hubei on exploration, development and supply chains ^[10].
• **[NEW] Copper recycling:** SMM posted a conference item addressing pollution reduction, carbon reduction and countermeasures for recycled copper, but the excerpt supplied no metrics or policy details ^[6].

3. Contrarian Read and Falsifiers

• **[ONGOING] Narrow conclusion:** The nonferrous rally covered every quoted LME name except lead, but weaker energy and chemical contracts at the night open argue against reading it as a blanket commodity upswing ^[1][3].
• **[NEW] Falsifiers:** The next source-based checks are the persistence of Guinea's bauxite exports, PT Timah's tin output and share, the direction of aluminum-processing fees and progress on Ansteel's procurement; the packet does not quantify how any of these should move LME prices ^[4][5][8][9].
• **[NEW] Source cautions:** PT Timah's 37% share is an ITA estimate contained in a truncated excerpt, Guinea's export figure is a government claim relayed by Jin10, and the Hubei meeting provides no project volume, spending or timetable ^[10][4][8].
• **[ONGOING] Timestamp discipline:** Zinc's earlier $3,903/t, +2.00% intraday mark must remain separate from its $3,892/t, +$50/t close ^[1][7].
