〔Day Digest〕Aluminum Upstream Profits Double While Midstream Lags; Lithium Slips 500 Yuan to 150,950; Copper Defends $14,000 Post-Treasury — Strategic Mineral Hunt Steps Up

0. Daily Arc

A clear value-chain split defines the tape: A-share aluminum H1 earnings double upstream and lag midstream ^[1], while MMLC battery-grade lithium carbonate loses another 500 yuan/ton to 150,950 ^[2]. Copper holds above $14,000/ton in the wake of a US Treasury intervention to rein in borrowing costs ^[3], and the Ministry of Natural Resources pushes to accelerate a new round of strategic mineral exploration ^[4]. Net: state policy and Treasury plumbing now sit alongside fundamentals as price drivers ^[3][4].

1. Aluminum Value Chain — Earnings Divergence [ONGOING]

• **[ONGOING] Upstream:** electrolytic aluminum producers reported net profit attributable to parent more than doubling, per Shanghai Securities News, as year-to-date electrolytic aluminum prices stayed elevated ^[1].
• **[ONGOING] Midstream:** aluminum processing companies posted weaker profit elasticity; the structural pattern is now clear across the segment ^[1].
• **[ONGOING] Downstream:** demand ran hot/cold; industry profit concentrated further in the high-end aluminum materials track ^[1].
• Source control: the "doubling" headline rests on Shanghai Securities News' read of H1 reports ^[1]; precise percentages by ticker are not in the packet and should be cross-checked against company filings ^[1].

2. Lithium Carbonate — Daily Reset [NEW]

• **[NEW]** MMLC battery-grade lithium carbonate morning-session price fell 500 yuan/ton from the prior day to a midpoint of 150,950 yuan/ton, per Mysteel ^[2].
• The 500 yuan move is a routine daily fix; the content is the tape direction, not the absolute step ^[2]. Watch the next fix for follow-through on the 150,950 handle ^[2].

3. Copper — Treasury Tailwind [NEW]

• **[NEW]** Copper held above $14,000/ton after the US Treasury's surprise intervention to rein in borrowing costs ^[3].
• Mechanism: a duration/rate action compresses real yields and the dollar, supporting the red metal; the open question is whether the move transmits into physical industrial-metals demand or stays a financial-conditions story ^[3].
• Source control: the Treasury-and-copper link is a single Bloomberg headline; flag it as headline-driven, not yet corroborated by a second wire ^[3].

4. Policy — Strategic Mineral Hunt [NEW]

• **[NEW]** The Ministry of Natural Resources, at an August 19 meeting, called to accelerate a new round of strategic mineral exploration breakthroughs and push reserves and production higher ^[4].
• Same meeting also called for: an integrated "one map" of land-use planning, a marine-economy policy rollout, continued push on the "Three-North" shelterbelt program, and geographic-information infrastructure build-out ^[4].
• Mechanism: state-led reserve expansion lifts upstream capex and exploration-services demand; the read-through to listed miners is the open variable ^[4].

5. What Decides Next

• Lithium follow-through: whether the next MMLC fix breaks the 150,950 yuan/ton midpoint ^[2].
• Midstream aluminum margin recovery on cost pass-through, per the H1 filings flow ^[1].
• Whether the Treasury action extends beyond duration into broader metals demand and the dollar ^[3].
• Falsifiable test: the next MMLC fix, the next batch of midstream aluminum H1 reports, and any follow-through Treasury action ^[2][1][3].
