There is a geopolitical race to build rail. The US/EU are funding the Lobito Corridor (Angola-DRC-Zambia), and China is spending $1.4B to refurbish the Tazara railway (Zambia-Tanzania). This is government-guaranteed infrastructure spending. It benefits the engineering and construction firms contracted to build these lines. Furthermore, improved logistics lower the "all-in sustaining costs" (AISC) for miners in the region, making the miners themselves more profitable. LONG. Infrastructure plays and the miners that utilize these specific corridors. Project delays or geopolitical friction slowing down funding disbursement.
