Shared Transport Infrastructure to Support Mineral Exports
Shared Transport Infrastructure to Support Mineral Exports
Context
Efficient, reliable transport infrastructure is essential for moving critical minerals from production sites to processing facilities and export markets. In Southern Africa, mining operations are often located far from major transport hubs, requiring costly private investment in roads, rail, and related logistics. Fragmented or single-user infrastructure increases costs, limits economies of scale, and reduces competitiveness in global markets.
Shared infrastructure models — where multiple sectors, users, and countries benefit from the same transport corridor, can lower costs, improve efficiency, and deliver wider socio-economic benefits.
One example is the Bakwena Platinum Corridor, a 385 km toll route connecting Pretoria to the Botswana border, which plays a key role in transporting platinum group metals (PGMs) and other commodities across the region.
Through shared infrastructure development, including toll systems and traffic control centers, the region saw reduced transport costs, job creation, and significant community development.
Challenge
SADC mining operations, especially those focused on critical minerals like lithium, cobalt, and rare earth elements, are often isolated and underserved by infrastructure. Fragmented infrastructure investments increase costs, slow timelines, and reduces the global competitiveness of mineral exports.
Environmental, social, and governance (ESG) concerns, from local employment to emissions, compound these challenges. Many SADC miners must independently finance roads, energy, and water, discouraging new entrants and stifling regional integration.
Approach
The Bakwena Platinum Corridor has helped facilitate transportation financing for critical minerals[ii]:
- Leveraging private equity: Expertise from AIIM leveraged in the fields of project finance, hedging and risk management, funding secured through debt markets
- Debt refinancing: In 2009, Bakwena refinanced ZAR 3.7bn of debt, which was the largest infrastructure project refinancing in South Africa at the time. This helped to create a more robust financial structure, along with ensuring long term financial sustainability
- User-Pay Principle in roads: This approach allows those who use the roads to directly fund their maintenance and operation through tolls or fees. It reduces dependence on public budgets and promotes more sustainable infrastructure financing.
- Electronic tolling: South Africa’s first electronic tolling system, streamlined toll collection and enhanced operational efficiency, this also helped in optimizing the required capital expenditure
Conditions
Several conditions supported the success of this shared infrastructure model:
- Public-Private Partnership (PPP) Model: The project was structured through a 30-year concession agreement between SANRAL and Bakwena, enabling efficient infrastructure delivery via a public-private partnership[iii].
- Government policies: Regulatory frameworks provided structure for multi-stakeholder collaboration and consistent project delivery for example, through the concession agreement framework used in public-private partnerships
- Anchor Investors: AIIM and Old Mutual Alternative Investments provided critical equity and financial expertise, enabling the successful R3.7 billion debt refinancing and long-term capital alignment[iv].
- Institutional Coordination: Cross-agency coordination ensured integration of logistics, safety enforcement, and local development priorities along the corridor.
- Technology Integration: The rollout of interoperable electronic tolling systems enhanced efficiency, reduced delays, and supported real-time traffic and revenue management[v].
Observed Impact
The shared infrastructure approach yielded benefits including:
- Efficiency Gains: Export timelines reduced due to optimized logistics and fewer road downtimes.
- Traffic Control for Overloading: Bakwena implemented traffic control centers to monitor and reduce vehicle overloading, mainly from mining trucks. This initiative helped minimize road surface damage, lower CO₂ emissions from road reconstruction, and increase road safety, indirectly benefiting the environment.
- Employment Creation: Over 4,800 jobs created along the Bakwena corridor — 3,300 during initial construction and 1,500 through the life of the concession[vi]
- Regional Integration: The corridor links mineral-rich zones across South Africa, Botswana, Zimbabwe, and Namibia (SADC Transport Strategy).
- Social Uplift: R130.5 million invested in health, education, and environmental initiatives along the corridor[vii].
What's Next for the Southern African Region
The Southern African Region holds vast reserves of critical minerals for clean energy. Building on the PGM sector’s shared infrastructure model, member states could:
- Identify Strategic Corridors: Conduct geological and infrastructure mapping across lithium, copper, and rare earth zones.
- Facilitate Investment Platforms: Launch blended finance and sovereign guarantee-backed investment vehicles.
- Strengthen Regional Governance: Harmonize infrastructure and mining regulations across borders[viii].
- Incentivize Collaboration: Implement tax reliefs, fast-track licensing, and support for shared infrastructure.
- Replicate Success: Apply the model to lithium (Zimbabwe), copper (Zambia-DRC), and REE corridors (Namibia) with development bank support.
Through collaborative infrastructure, SAR countries could fast-track the development of their mineral wealth, support a just energy transition, and foster regional prosperity.
