Ministère des Mines et de la Géologie (MMG/BSD) / Institut National de la Statistique (Guinea)
Guinea NAMED per-company bauxite production + export tonnages from the MMG/INS statistical bulletins - the aluminum supply chain's ORIGIN (Guinea is the world's #1 bauxite exporter, ~86% to China). Annual bulletins carry full-year production by société; the freshest is auto-adopted - FY2025 (Bulletin n30) = 19 named majors / 182.8 Mt (SMB 71.5 Mt, CHALCO 22.1, CBG 17.4, AGB2A 17.0, CDM Chine 9.4...), a ~48% jump on FY2023's 123 Mt. Quarterly bulletins carry per-société export (Total Exportation reconciles to the bulletin's stated quarter total). BACI/Comtrade show only the Guinea-China country total, so these are the only free source naming who mines/ships it

Feed (what to expect)
Bulletin PDFs archived via `strata gn-mmg pull` (three discovery surfaces: the mines.gov.gn WordPress media API, the stat-guinee.org homepage quarterly, and itie-guinee.org WP posts which carry the NEWEST annual - the media library lags, stalled at n22/FY2023 while itie has n30/FY2025; idempotent by basename). The bauxite per-société tables parse to named-company SupplyRecords: annual bulletins -> production, quarterly -> export. Bauxite is the ore stage, routed to the bauxite_alumina commodity (not the aluminum metal).

Same lane class as DRC CTCPM (cd_ctcpm) - a mines-ministry per-company ledger that pierces the Guinea->China bauxite wall. Verified: FY2025 annual production 182.8 Mt across 19 named majors (n30); FY2023 123 Mt (n22); No.20 T2-2023 export 32,888 kt = the bulletin's own stated total.
