- Mahama Warns Mining Companies to Prepare for Ghana’s 2030 Raw Mineral Export Ban
President John Mahama has put mining companies operating in Ghana on notice that the country intends to prohibit the export of unprocessed mineral ores by 2030, escalating the government’s push to retain a greater share of the value generated from its natural resources.
Addressing the Council on Foreign Relations in New York, President Mahama said companies currently extracting Ghana’s minerals should begin investing in local processing facilities ahead of the proposed deadline.
“By 2030 we’re not going to export any raw ores,” the President said, adding that miners should undertake “at least primary and secondary processing” in Ghana.
The policy could affect manganese, bauxite, iron ore and future lithium production more directly than gold, which large-scale producers already process into semi-refined doré before export.
But the broader message to investors is unmistakable: access to Ghana’s mineral resources will increasingly be tied to the amount of processing, industrial activity, employment and technology transfer that companies establish within the country.
The announcement forms part of the administration’s effort to reposition mining from an export enclave into a foundation for domestic industrialisation.
Ghana has mined gold for more than a century and possesses significant deposits of manganese, bauxite, diamonds and lithium. Yet much of the value created after extraction—including refining, fabrication, manufacturing and specialised services—continues to accrue outside the country.
The 2030 deadline seeks to alter that model. Its success, however, will depend on whether the government can turn a presidential declaration into an enforceable and economically workable national policy.
The immediate weakness in the proposed ban is that it has not been enacted into law.
Ghana currently has no general legal requirement compelling all minerals to be processed domestically before export. The Minerals and Mining Bill presented to Parliament in May would give the sector minister powers to prohibit exports of unprocessed mineral concentrates and require local processing.
But those powers would have to be activated through separate regulations. The bill itself does not set a 2030 deadline or make the prohibition automatic.
That legal gap is significant because mining investments are based on long-term assumptions covering production, infrastructure, taxation and access to export markets.
Companies cannot construct refineries, smelters or mineral-processing plants based solely on political speeches. They will require clear definitions of what constitutes “raw” or “processed” material, realistic implementation schedules and certainty about the penalties for non-compliance.
The distinction will be particularly important for lithium. Ghana’s Ewoyaa project is designed to produce spodumene concentrate, which is processed beyond the raw ore stage but remains several steps removed from the lithium chemicals required for battery manufacturing.
Would exporting concentrate satisfy the government’s policy, or would companies be required to establish chemical conversion facilities in Ghana? The answer could materially alter project costs and investor decisions.
The timing creates a second difficulty.
President Mahama’s constitutionally final term ends in January 2029, a year before the proposed ban is expected to take effect. Implementation would therefore depend on his successor maintaining the policy and completing the required legal and regulatory work.
This transforms the proposal from a presidential commitment into a test of institutional continuity.
Mining companies may hesitate to commit substantial capital if they believe the deadline could change after the 2028 elections. Conversely, delaying investment in anticipation of a policy reversal could leave them unprepared if the next administration retains the ban.
The government must therefore secure broader political and parliamentary support before 2029. A policy with cross-party backing would be more credible than one dependent on the tenure of a particular president.
Ghana has made similar value-addition commitments before. Former President Nana Akufo-Addo told Parliament in 2024 that his administration intended to prohibit raw bauxite exports and said negotiations for a $450mn manganese refinery were nearing completion.
The persistence of the problem across administrations suggests that the main constraint has not been a shortage of political declarations. It has been the difficulty of assembling reliable energy, financing, transport infrastructure, technology and commercially sustainable processing capacity.
In the gold industry, the administration has already moved beyond rhetoric.
Since July, large-scale miners have been required to sell 30 per cent of their production to the Ghana Gold Board in doré form for local refining. Payments are made in cedis at the Bank of Ghana reference rate and at a fixed discount.
The government also wants at least one Ghanaian refinery to secure London Bullion Market Association accreditation by 2030, which would allow locally refined bullion to gain wider acceptance in international markets.
GoldBod has entered agreements with two domestic refineries, while exporters of artisanal gold have been prevented from shipping unrefined doré without confirmation that the metal has been refined locally.
These interventions offer an early indication of how the wider mineral policy may operate: access to export markets could become conditional on selling part of production locally or meeting minimum domestic-processing requirements.
But gold also illustrates the complexity of value addition. Refining gold domestically can retain fees, improve traceability and support reserve accumulation. It does not automatically create the extensive industrial linkages associated with jewellery production, electronics manufacturing or financial products backed by locally refined bullion.
Local processing must therefore be connected to a broader industrial strategy rather than treated as an end in itself.
A prohibition without sufficient processing capacity could leave mineral producers with output they cannot legally export and local facilities unable to absorb.
Manganese and bauxite processing require large, reliable supplies of electricity and substantial investment in transport and industrial infrastructure. Lithium conversion demands specialised technology, chemicals and environmental controls.
If Ghana’s energy and logistics costs make local processing significantly more expensive than competing locations, the ban could reduce new investment or encourage companies to delay production.
The government will need to determine whether processing plants should be built by individual miners, joint ventures, private specialist operators or public-private partnerships serving multiple producers.
It must also decide what incentives, tax relief, infrastructure support, power arrangements or financing guarantees it is prepared to provide without recreating the generous concessions that have sometimes reduced the state’s mining revenues.
Ghana’s objective is economically defensible. Exporting raw ore also exports potential jobs, industrial knowledge and downstream revenue.
Yet the 2030 deadline will be credible only when it is supported by law, energy, infrastructure, commercially viable processing plants and a policy capable of surviving a change of government.
The President has given mining companies four years’ notice. The more difficult question is whether the state can use those four years to build the conditions that make compliance possible.
