    Mining data transparency: what EITI revenues mean for project economics

    Mining data transparency: what EITI revenues mean for project economics

    First reported on MINING.com

    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.

    DfT secrecy on Cosco UK port presence: risk takeaways for port engineers

    The Department for Transport has refused a freedom of information request to disclose what port facilities Chinese state-owned Cosco Shipping operates in the UK, after US officials alleged the firm has enabled Beijing to monitor US military communications. The decision limits public visibility of Cosco’s role in UK container terminals, logistics hubs and potential access to critical maritime data infrastructure such as fibre links and port management systems. Port planners, marine engineers and security consultants may face tighter scrutiny on future concessions, terminal upgrades and digital systems involving Chinese operators.

    £10.5bn UK flood defences: pipeline and design implications for engineers

    The UK government is creating a Flood and Drought Resilience Taskforce alongside a £10.5bn funding commitment for flood defences between 2024 and 2036. The programme will target long‑term protection against extreme rainfall and prolonged dry spells, signalling sustained investment in river embankments, coastal defences, storage reservoirs and urban surface‑water schemes. Civil and geotechnical teams can expect a steady pipeline of appraisal, design and upgrade work, with closer integration of hydrological modelling, asset condition data and climate‑change allowances in line with current Environment Agency practice.

    AME tax breaks proposal: exploration uplift and project pipeline lens

    Expanding Canada’s mining tax incentives to include engineering, feasibility and technical studies as Canadian exploration expenses could lift exploration spending by up to US$1.1 billion (C$1.6 billion) per year, EY estimates for the Association for Mineral Exploration. EY projects this could advance three to five additional mines, adding C$5.2–12.2 billion to GDP from exploration and a further C$12.9–21.4 billion over mine construction plus 15–20 years of operations, against C$6.6 billion in forgone tax revenue over a decade. Budget 2025 currently proposes excluding feasibility-related costs, despite support for broader eligibility from six provinces and Yukon.
