Arrow Minerals, the West Africa-focused bauxite explorer, has announced that it's putting a hold on operations at its Niagara bauxite project in Guinea. The reason is the ongoing dispute about whether its mining permits are valid. The Australian miner reported this in its September 8 half-year update.
The Guinean military-led government annulled 129 mineral exploration licenses to reclaim inactive permits and transfer rights to more active investors. The licenses were cancelled without prior discussion to tighten government control over resources.
The move may shut down idle projects, cause losses for inactive license holders, and shift the regional mining investment landscape, creating opportunities for operators that actively engage and meet local development expectations.
EGA has officially halted all bauxite mining operations in Guinea after the government decided to take over its mining assets. The Guinea Alumina Corporation (GAC) mining concession, which is estimated to contain about 400 million tonnes of bauxite, was revoked as of August 6, 2025, due to claims of not following national mining regulations. This concession has now been handed over to a state-backed entity without any compensation. This move is likely to cause a major disruption in the global bauxite supply chain and create significant risks for stakeholders who rely on EGA's output from Guinea.
Now, Arrow Minerals is on the same path
In the first six months of 2025, Arrow Minerals advanced exploration and development at its Niagara and Simandou North projects. Drilling at Niagara has confirmed the presence of high-grade mineralisation, which is promising enough to support a maiden mineral resource. A scoping study by SRK Consulting has been completed, but the results will only be shared once the permit status is clarified.
The firm recently entered into a nonbinding Memorandum of Understanding (MoU) with Baosteel Resources, which is part of the Baowu Group, to explore the possibility of future iron ore offtake from Simandou North. The company noted further progress depends on resolving the tenement status with the government.
Four months later, the company awaits formal confirmation on the licenses. Getting clarity on the Niagara permit is crucial for Arrow to move forward and finalise its preliminary economic study for the project.
The company stated, "In light of the uncertain regulatory environment, Arrow has prioritised capital preservation by suspending all project-based activities, reducing corporate costs and maintaining active engagement with relevant Guinean stakeholders.”
The firm expressed strong confidence in the quality of its projects and highlighted the significant technical work completed so far.
Guinea's authority on Arrow Mineral's take
Guinean officials have not made any announcements about the current situation, which means the development of a bauxite deposit estimated to hold around 185 million tonnes of resources is stuck in limbo. The preliminary economic study, which was supposed to come out in the first half of 2025 to outline initial operating costs and a feasible mining plan, is now facing some uncertainty about when it will actually be published.
Guinea's bauxite mining is an ongoing reality
Guinea accounted for roughly 73% of global seaborne bauxite exports in the first seven months of 2025. Exports from Australia, Sierra Leone, and Cameroon are increasing. This could see the total export capacity outside of Guinea jump from around 60 million tonnes per annum in 2024 to over 90 million tonnes by 2029 to 2030, potentially reducing Guinea’s share to below 70 per cent.
Guinea's bauxite export capacity is facing increasing challenges in the domestic realm as the ruling junta ramps up its resource nationalism strategy in anticipation of the December 2025 elections. Recent license cancellations for EGA’s GAC unit and Axis Minerals, now transferred to a state-run company, have raised concerns over policy unpredictability for foreign investors.
The Simandou iron ore project may divert skilled labour, strain port logistics, and overshadow bauxite exports with higher margins. Government focus on iron ore profits could pressure bauxite miners for greater commitments, potentially limiting export growth.
Guinea's alumina ambition at stake
Guinea’s plan to shift from raw bauxite exports to alumina refining faces significant challenges. The country is grappling with poor infrastructure, political instability and unfavourable global market conditions. Alumina refining is energy-intensive and demands major investments in power, transport and port infrastructure, increasing capital costs and project risks.
Political uncertainty before the December 2025 elections and rising labour unrest are deterring investors. A global alumina oversupply over 30 million tonnes per year from China, Indonesia and India which could constrain export markets and question the long-term economic viability of Guinea’s projects.
Guinea's bauxite exports skyrocketed to 99.8 million tonnes in the first half of 2025, almost reaching the total for the entire year of 2022, which was 102.28 million tonnes, representing a surge of 39 per cent. This impressive growth is primarily fueled by robust demand from China and an increase in shipments from the top exporters. The output for the first half of 2025 shows a remarkable 36 per cent increase compared to the same period in 2024. This growth highlights Guinea's pivotal position in the global raw bauxite supply chain, even as the government intensifies its push for commitments to downstream processing and refining.

EGA balances Guinea access with Ghana expansion
EGA continues to source Guinean bauxite via third-party traders after its GAC subsidiary withdrew following the late-2024 export ban. In August, the Al Taweelah alumina refinery welcomed its second shipment from Guinea this year, with the Capesize Navios Luz bringing in over 172,000 tonnes. This highlights how crucial Guinean ore is for the refinery, especially as it makes adjustments to handle different feedstocks.
The company is diversifying its supply, with Ghana emerging as a key supplier. In August, Al Taweelah brought in an impressive 55,000 tonnes of bauxite from Ghana, setting a new record for monthly imports. This achievement, along with the completion of a debottlenecking project that's projected to increase alumina output by 0.5 million tonnes each year, demonstrates its approach of maintaining access to Guinean resources while establishing alternative supply routes for resilience.
