〔Overnight Brief〕Indonesia Floats Nickel-Moratorium as LME Tin Tops $54,279/t and Copper Adds $60 to $14,476, but Zinc -2.7% and COMEX Aluminum -1% over Golden Week - Supply Floor vs Holiday Drag

0. Overnight Arc

A divergent LME close — copper +$60 to $14,476/t, tin +$95 to $54,279/t, nickel +$53 to $15,735/t, lead +$24 to $1,896/t — but aluminum -$16 to $3,117/t and zinc -$2 to $3,764/t ^[1]. The upside ran on an Indonesian policy signal: senior mining minister Bahlil Lahadalia said Jakarta is weighing a moratorium on new nickel semi-finished processing capacity to absorb excess and lift prices ^[2][3]. The downside read as residual Golden-Week overhang, with COMEX aluminum down >1% to $3,213.5/t ^[4] and SMM's holiday review putting LME zinc down 2.7% over the holiday ^[5].

1. Supply-Side Catalyst — Indonesia

• **[NEW] Indonesia nickel moratorium (Bahlil Lahadalia, senior minister for mining, Wednesday):** said the government is "considering compressing" capacity for semi-finished nickel products and "may impose a halt", alongside continued mining-quota controls, to support prices ^[2]. Kitco relay frames the plan as part of efforts to prop up nickel-product prices ^[3]. Indonesia is the world's largest nickel exporter, with most shipments being NPI/ferronickel rather than finished metals ^[2].
• **[NEW] (single source) Peru:** two people killed in a clash at a mine in northern Peru — no operator identified, no asset named ^[6].

2. Lithium

• **[NEW] LG Energy Solution – Elevra:** multi-year spodumene concentrate supply agreement from Canada ^[7]. Single-source; no tonnage, price or offtake volume disclosed in the report ^[7].

3. Tin and Lead Microstructure

• **[NEW] Alphamin Resources (TSXV: AFM; JSE: APH), via the International Tin Association:** Q3 tin-in-concentrate output 5,030 t, sales 5,046 t, EBITDA $171M (+2.2% QoQ), supported by steady grades, mining rates and stronger tin prices ^[8].
• **[NEW] LME lead, SMM holiday review:** LME lead ended the Golden-Week stretch down only 0.5%, with the Oct 7 Asian electronic session at $1,881.5/t by 18:00 Beijing; the LME settle printed +$24 at $1,896/t ^[1][9]. On-warrant LME stock drew 7,200 t to 349,400 t by Oct 6, with the cancelled-warrant ratio rising to 10.3%; off-warrant Singapore stocks accumulated 8,800 t ^[9]. Net read: apparent destocking masked by warehouse relocation, not real consumption ^[9].
• **[ESCALATED] LME tin:** settled +$95 at $54,279/t ^[1], against a backdrop of an in-line Alphamin Q3 ^[8] and the Indonesian supply-discipline signal ^[2].

4. Holiday Drag — Zinc and Aluminum

• **[NEW] LME zinc, SMM holiday review:** LME zinc closed Golden Week down 2.7% from the Sept 30 print, touching $3,693/t on Oct 2 before recovering to $3,763/t by Oct 7 18:00 Beijing ^[5]. Cash-3M backwardation narrowed from $85.77/t on Sept 30 to $39.1/t on Oct 6; on-warrant stock rose 3,800 t to 127,800 t ^[5].
• **[NEW] Aluminum:** COMEX aluminum fell >1% to $3,213.5/t ^[4]; LME aluminum settled -$16 at $3,117/t ^[1]. Single-source on the COMEX print ^[4].

5. Contradictions and What Decides

• Indonesia's signal is intent, not yet policy: Bahlil said "considering" and "may impose" ^[2]. The falsifiable test is whether a formal moratorium order is published and which downstream projects it covers ^[2][3].
• LME tin +$95 and copper +$60 sat against aluminum -1%+ and zinc -2.7% over the holiday ^[1][4][5] — base-metals dispersion, not a single supply-side narrative.
• Source quality: the LG–Elevra deal ^[7], the Peru fatality ^[6] and the COMEX aluminum print ^[4] are single-source; the Indonesian moratorium is corroborated by Kitco ^[3] and the Chinese-language relay ^[2].
