## ARTICLE:

Mauritania is undergoing a critical infrastructure transformation. The North African nation is upgrading its railway network to support a new generation of mining projects that could reshape regional supply chains and attract billions in foreign direct investment over the next decade.

### What is Mauritania's rail upgrade strategy?

The upgrade centers on expanding existing rail corridors—particularly those connecting the Tasiast-Tabarbart region to Port Nouadhibou—to accommodate higher tonnage capacity and frequency. Currently, Mauritania's rail infrastructure is dominated by the state-owned Société Nationale Industrielle et Minière (SNIM), which operates the world's longest iron ore train at 2.67 km. The planned upgrades target capacity increases of 30–50% within 18 months, with modern signaling systems and improved rolling stock. These enhancements address bottlenecks that have constrained mining operators seeking to export copper, gold, and rare earth elements alongside traditional iron ore.

The timing is strategic. Multiple junior mining companies—including Kinross Gold, Perseus Mining, and emerging copper explorers—have secured concessions in Mauritania's interior. However, logistical constraints have delayed project development. A modernized rail network removes this friction, enabling greenfield projects to reach bankability faster.

### Why does this matter for investors?

Mauritania holds 90+ million tonnes of proven iron ore reserves and emerging copper deposits estimated at 10+ million tonnes. Current production capacity utilizes only 40% of available rail bandwidth. The upgrade unlocks latent economic value: each 1 million tonnes of additional annual export capacity generates ~$150–200 million in government revenue and operator earnings, depending on commodity prices.

For diaspora investors and fund managers tracking African mining exposure, this is significant. Mauritania's business environment has improved markedly since 2019, with improved mining code provisions and tax stability agreements. A functioning rail backbone mitigates operational risk for mid-tier producers, lowering their cost of capital.

Port infrastructure is also critical. Nouadhibou's container and bulk terminals are being dredged to 14.5 meters, enabling Panamax vessels (the largest ships fitting the original Panama Canal dimensions) to load directly. This reduces shipping costs by 12–18% versus transshipment via Dakar or Abidjan.

### When will the upgrade be operational?

Phase 1 (2025–2026) focuses on track rehabilitation, signaling upgrades, and fleet acquisition. Phase 2 (2027–2028) targets capacity doubling. Private operators—including ArcelorMittal-backed entities and Chinese rail developers—are co-financing under public-private partnership (PPP) models. First tangible increases in throughput should appear in Q3 2026.

### Market implications and risks

Commodity price volatility remains the primary headwind. Iron ore trades in a $80–$140/tonne range; copper swings wider. A sustained downturn could delay project finance closures. Geopolitical risk is secondary but real: Mauritania borders Western Sahara (disputed territory) and Mali (conflict-affected). However, mining zones are geographically separated from tensions.

For international investors, currency risk is moderate—Mauritania's ouguiya is managed and IMF-compliant. Debt sustainability is improving as SNIM dividends flow to treasury.

**The bottom line:** Mauritania's rail upgrade is not hype. It is a material unlock for African mining supply chains, with direct benefits for copper, gold, and rare earth supply to European and Asian markets. Investors should monitor Phase 1 completion metrics and junior miner financing announcements through 2026.
