〔Day Digest〕5.56 Mt/y Tailings-Iron and Bayanbaolege Permit Land; Brazil Halts Sigma's Grota do Cirilo — Substitution Meets Single-Jurisdiction Risk

0. Daily Arc

Two Chinese supply moves — a 5.56 Mt/y iron-from-tailings production line and a renewed lead-zinc polymetallic exploration title — landed in the same session as a court-ordered halt at Sigma Lithium's Grota do Cirilo project ^[1][2][3]. The pivot is jurisdictional: domestic Chinese capacity is being formalized ^[1][2], and overseas supply is exposed to a single court ruling ^[3].

1. Iron from Tailings — New Industrial Line

• **[NEW] CAS-confirmed facility:** a production line capable of processing 5.56 million tonnes/year of refractory iron ore and tailings has passed official checks and is running steadily, per the Chinese Academy of Sciences ^[2]. CAS framed it as a world-first at industrial scale; the play pairs waste monetization with import reduction — China is the world's largest iron ore user ^[2].
• Source quality: 5.56 Mt/y is a CAS-via-SCMP figure, not an independent engineering audit ^[2].

2. Lead, Zinc, Silver — Shengda / Deyun in Inner Mongolia

• **[NEW] Permit renewal:** Deyun Mining (Shengda Resources' controlled subsidiary) completed renewal of the Bayanbaolege District lead-zinc polymetallic exploration permit in Ar Horqin Banner, Inner Mongolia, receiving the Real Estate Certificate (Exploration Rights) and Mineral Resources Exploration Permit from the Chifeng Municipal Natural Resources Bureau ^[1].
• **[ONGOING] Adjacent silver-polymetallic mining right:** production scale 900,000 tonnes/year, mining area 2.3206 sq km; Deyun Mining is processing pre-construction approval paperwork ^[1]. The exploration renewal and the mining right are two separate titles in the same district, with the silver mine still in pre-construction approval ^[1].

3. Lithium — Brazilian Court Halts Sigma

• **[ESCALATED] Sigma Lithium:** a Brazilian court ordered the suspension of all environmental permits for Sigma Mineração SA (the operating subsidiary) and the complete halt of mining activities at the Grota do Cirilo project ^[3]. The dispatch does not disclose a production resumption timeline, a permit restoration date, or the procedural posture of the ruling ^[3].
• Source quality: single-source so far — Bloomberg only ^[3]. The source does not specify which permits sit behind "all environmental permits" or whether the order is preliminary or final, so operational scope and legal standing remain thin pending court filings or company disclosure ^[3].

4. Source Control and What Falsifies

• **[NEW] Contradictions / thin sourcing:** the iron-from-tailings throughput is a single CAS announcement; the Sigma halt is a single Bloomberg dispatch; the Shengda permit items are company disclosure via a financial wire ^[1][2][3]. None of the three is independently audited ^[1][2][3].
• Falsifiable next prints: (a) any Sigma Lithium appeal, stay, or procedural-ruling update ^[3]; (b) completion of Deyun Mining's silver-mine pre-construction approval at the 900,000 tonnes/year site ^[1]; (c) a second Chinese tailings-iron capacity filing in the same regulatory window ^[2].
