〔Overnight Brief〕London Spot Clears $4,600 on Third Weekly Win (+5.18%) as Treasury Long-Bond Bid Lifts COMEX to $4,690 — Zhaojin Lags the 73% Sector Average, Options Expiry Caps the Breakout

0. Weekly Arc

Gold ripped higher for a third straight week. London spot cleared $4,400, $4,500 and $4,600 in succession for a 5.18% weekly advance, while COMEX futures tagged $4,690/oz — a more than 16% rebound from the $4,022 July low ^[1]. Flash reports attribute the leg to a US Treasury long-bond bid rather than incremental liquidity ^[2][3], yet Jinshi flags the options-expiry roll as the immediate technical test ^[2]. The producer cohort is bifurcated: the six A-share miners that reported H1 averaged 73% net-profit growth ^[1], while Zhaojin Mining printed 9.61% attributable-profit growth on 29.38% higher revenue ^[4].

1. Price Action and the Treasury Bid

• **[NEW] Three-week win, three round numbers:** London spot closed above $4,600/oz (+5.18% w/w); COMEX peak $4,690/oz, +16% from the $4,022 July low ^[1].
• **[NEW] Long-bond backstop (single-source / unverified):** two Jinshi flashes within ~65 minutes tie the leg higher to US Treasury intervention in long-dated debt, with the second explicitly stating the driver is not liquidity ^[2][3]. Both items are teaser copy with no underlying figures, mechanism or named source ^[2][3].
• **[NEW] Options expiry as near-term variable:** Jinshi flags the roll as the short-term cap on spot; no strike, notional or skew data provided ^[2].

2. Miners Print Earnings, but Zhaojin Lags

• **[NEW] Sector average:** the six A-share gold miners that disclosed H1 results averaged 73% net-profit growth against a 50%+ YoY rise in London spot; three doubled net profit ^[1].
• **[NEW] Zhaojin Mining (600547.SH / 1817.HK):** H1 revenue 9.022 billion yuan, +29.38% YoY; net profit attributable to parent 1.578 billion yuan, +9.61% YoY; total net profit 2.105 billion yuan, +18.50% YoY; basic and diluted EPS 0.42 yuan, +10.75% YoY; no interim dividend ^[4]. The 9.61% attributable figure trails the 73% sector average by ~63 percentage points; even the 18.50% total-net-profit print underperforms the cohort ^[1][4].
• **[NEW] Equity flow:** gold-stock ETFs up more than 20% month-to-date; limit-up moves across the A-share and HK board ^[1].

3. Cross-Market and Geopolitical Tape

• **[NEW] Tehran record (single-source / unverified):** gold in the Tehran market hit a record high per a Jinshi flash; no price level, currency basis or named source ^[5].
• **[ESCALATED] Treasury-channel narrative:** a second Treasury-backstop mention from Jinshi within ~65 minutes frames the long-end bid as the dominant narrative for the gold leg, not the dollar ^[2][3]. Source quality is thin — both are teasers, and the mechanism is asserted rather than documented ^[2][3].

4. Silver and PGM Note

• **[NEW] No overnight material:** no silver, platinum or palladium prints were filed in this packet. PGM prices, ETF flows and silver-to-gold ratios cannot be quoted from the supplied items and are deliberately omitted rather than estimated.
