Strengthening Mineral Supply Chains Through Targeted Infrastructure Investment
Context
Efficient transport and reliable energy infrastructure are critical to unlocking the value of Southern Africa’s mineral resources. Growing global demand for critical minerals such as copper and manganese—key inputs for electric vehicles, renewable energy systems, and other clean technologies—has placed increased pressure on the region’s logistics corridors, port capacity, and power supply.
However, the movement of minerals from mine to market is often constrained by a combination of factors: congested border posts, underutilized or deteriorating rail infrastructure, imbalanced freight flows, power shortages, and lengthy lead times for major infrastructure projects. Addressing these constraints is essential to reduce costs, shorten delivery times, and increase the competitiveness of Southern Africa’s mineral exports.
Challenge
Across the region, the development and export of critical minerals face five common, interlinked infrastructure bottlenecks:
- Inefficient border crossings: Some high-traffic border posts experience delays of days or even weeks. [i]
- Underutilized rail networks: Poor rail infrastructure and lack of coordination between operators force excessive reliance on road transport, increasing costs and transit times. [ii]
- Unbalanced freight flows: Mineral exports often lack return cargo, leading to inefficient “empty leg” hauls. [iii]
- Power constraints: Chronic electricity shortages and outages disrupt mining and processing operations.[iv]
- Long lead times for major projects: Large, capital-intensive projects can take years to reach feasibility, even when smaller, high-impact upgrades to existing infrastructure could deliver quicker gains.
Approach
Regional and international investors have adopted a range of strategies to address these bottlenecks:
- Investing in port and corridor infrastructure to relieve congestion and improve export reliability.
- Revitalizing rail networks by opening access to private operators, coordinating between regional rail systems, and integrating road–rail interfaces.
- Unlocking private energy supply through renewable generation, wheeling arrangements, and aggregation platforms that pool demand across industrial users.
- Balancing scalable, high-impact upgrades with longer-term greenfield projects, ensuring immediate gains while building future capacity.
One example of this approach is the work of African Infrastructure Investment Managers (AIIM). AIIM’s portfolio includes critical transport nodes such as bulk terminals at major ports (e.g., Durban, Maputo, Walvis Bay) and inland logistics hubs that service key mining regions. It has also invested in renewable energy platforms such as African Clean Energy Developments, NOA Group Holding, and Solar Africa to expand clean energy access for industrial and mining clients.
Conditions
Several conditions help to create an environment where such infrastructure investments can succeed:
- Strategic asset ownership and coordination: Consolidated control or effective partnerships across corridors enable integrated planning, as seen in the TRAC N4 Toll Route and linked bulk terminals at the Ressano Garcia border and Maputo Port.
- Anchor industry partnerships: Collaboration with mining companies and energy off-takers ensures that infrastructure capacity aligns with actual demand, reducing investment risk.
- Supportive regulatory frameworks: Examples include Mozambique’s landlord port model and South Africa’s gradual liberalization of rail and electricity markets, both of which help attract private capital.
- Integrated regional planning: Platforms like the Southern African Power Pool (SAPP) and SADC infrastructure frameworks can improve cross-border coordination and economies of scale, though their effectiveness varies by sector.
Observed Impact
Targeted investments in strategic corridors have shown measurable efficiency gains:
- Reduced border delays: On the Maputo corridor, integration of toll road, border terminal, and rail shuttle operations has cut round-trip times by 8–12 hours for bulk mineral exports such as chrome and magnetite.
- Expanded private power access: Energy aggregation models, such as those adopted by NOA Group, are enabling wheeled supply of renewable power from solar, wind, and battery storage projects to industrial users across multiple countries.
What’s Next for the Southern African Region
Experience from recent infrastructure investments suggests several priorities for the region:
- Scale proven corridor models to other trade gateways, reducing delays and increasing throughput for mineral exports.
- Rehabilitate and connect rail networks in underutilized routes (e.g., Zimbabwe, Malawi, Mozambique) to lower transport costs and emissions.
- Enable open-access regional power grids to support private generation and cross-border wheeling of renewable energy.
