Mining data transparency: what EITI revenues mean for project economics
Reviewed by Tom Sullivan

30 Second Briefing
Mining transparency rules under the Extractive Industries Transparency Initiative now cover 56 countries and about 3,900 entities, with governments disclosing $3.6 trillion in extractive revenue and using project-level models to renegotiate deals such as the DRC’s Sicomines copper-cobalt agreement, which lifted planned infrastructure investment to $7 billion from $3 billion. EITI-backed fiscal analysis has halted or reshaped major transactions, including Ghana’s proposed Agyapa Royalties sale and Porgera gold mine ownership in Papua New Guinea, and is informing Simandou iron ore revenue planning in Guinea. Ownership and trade data are also driving licence refusals, enforcement against illicit flows and due-diligence checks in Armenia, Ghana and Colombia, particularly for critical minerals.
Technical Brief
- EITI-commissioned audit of the DRC’s Sicomines deal identified unfulfilled infrastructure works and altered profit allocations.
- DRC extended fiscal modelling in 2025 to copper–cobalt operations covering ~80% of national mining fiscal receipts.
- Ghana’s proposed Agyapa Royalties sale (49% interest) was initially priced at US$500–750 million by government.
- Independent EITI-backed valuation using production and royalty data priced the same Agyapa stake at up to ~US$1.5 billion.
- Simandou modelling in Guinea projects US$850 million–1.7 billion per year in state revenue before 2035.
- Cameroon officially reported 22.3 kg gold exports in 2023 versus >15 tonnes recorded as imports by the UAE.
- Burkina Faso is estimated to have lost US$4.9 billion to illicit mining-related financial flows between 2012–2021.
- At Porgera in Papua New Guinea, EITI-informed negotiations lifted combined state and landowner equity from 15% to 51%.
Our Take
With Chile’s participation bringing more than 50% of global copper production under EITI reporting, copper-focused operators in Latin America now face a transparency baseline that our Policy coverage increasingly treats as standard rather than optional, especially where fiscal terms are being revisited.
The Porgera gold mine outcome, where Papua New Guinea and landowners lifted their interest to a majority stake, aligns with a pattern in our database of host governments in Africa and the Pacific using data-backed analyses to justify higher carried or equity interests in gold and iron ore projects such as Simandou.
