Critical minerals at the port, not the mine: logistics lessons for project teams

30 Second Briefing
China’s Belt and Road strategy is consolidating control over critical minerals not at the pit but along export corridors, exemplified by the US$20 billion Simandou joint venture that couples a multi‑hundred‑kilometre heavy‑haul railway with the new deep‑water port of Morabaya to channel Guinean iron ore directly to Chinese industry. In Africa’s Copperbelt, where 15% of global copper reserves and most known cobalt resources sit thousands of kilometres from deep‑water ports, foreign‑financed rail and terminals effectively dictate whether concentrates move as raw exports or into local refining. Djibouti’s Doraleh Multipurpose Port, 85% funded by China and offering deep‑water berths suitable for naval deployment, illustrates how dual‑use port ownership can weaponise logistics and blunt resource‑nationalist policies such as export bans on unprocessed lithium, graphite, copper and cobalt.
Technical Brief
- Central African Copperbelt ores must traverse multiple borders, rail networks, highways and customs posts before export.
- Export bans collide with logistics corridors engineered specifically for rapid outbound movement of unprocessed concentrates.
- Africa’s rail and maritime networks are configured for southbound manufactured imports and northbound raw mineral exports, not intra‑African trade.
- Commercial shipping lines lack incentive to run short‑haul routes between neighbouring African ports given low finished‑goods volumes.
- For future mine planning, corridor ownership and terminal control become as material as ore grade or strip ratio.
Our Take
The Central African Copperbelt’s 15% share of global copper reserves, combined with US efforts to link PEPFAR aid to copper and cobalt cooperation in Zambia in the 2026-03-16 piece, signals that logistics control in this belt is becoming as much a diplomatic lever as a mining one.
The $20 billion Simandou logistics JV and China’s 85% funding share in Djibouti’s Doraleh Multipurpose Port together indicate that Chinese capital is increasingly concentrated in iron ore and critical-mineral export corridors rather than individual mine ownership, which can complicate alternative offtake strategies for Western buyers.
Within our 139 Policy stories, relatively few explicitly tie maritime chokepoints like Bab el-Mandeb and the Cape of Good Hope to critical minerals such as cobalt and lithium, so this op-ed sits at the sharper end of work highlighting that port access and shipping routes may drive project bankability as much as ore grades in Africa.
