Guinea's mines in verified figures
The first independent observatory cross-referencing official data from the Ministry of Mines (Bulletin No. 30, year 2025) with market prices — every figure dated, sourced, labelled 'official' or 'estimate'. And we explain the gaps.

03 The gaps, explained
Crossing official data (MMG, EITI) with the market (IndexMundi) reveals gaps. We document them, we date them — and we explain them.
- Gold: SMD sells at USD 706/oz while the average reaches USD 2,905.80/oz. A price gap that questions revenue control — exactly the kind of gap EITI reconciliation helps investigate. See the gold page →
- Bauxite: ~USD 5.4bn of exported value (175.45 Mt × USD 30.72/t), ~USD 508m in mining taxes. Where does the value go? The MMG's official reference price brings operators closer to international markets — detailed calculation on the Prices page. See the prices page →
- CBG listed as 'N/A (convention)'. Its old establishment agreement places it outside the 2025 mining tax regime — a documented case, not a rumour. See the taxes page →
