Amid structural supply deficits in the global copper market, major miners are aggressively expanding capacity to secure long-term market positioning. Antofagasta's H1 2026 results demonstrated robust EBITDA growth and significant margin expansion. According to reports, the company is prioritizing water infrastructure investments to mitigate operational risks related to water scarcity and ensure production reliability.

The strategic expansions at the Centinela and Los Pelambres mines target a 30% increase in copper production while simultaneously lowering operational costs. However, cash conversion is currently lagging due to high capital expenditures and tax outflows associated with these large-scale infrastructure projects. Based on analyst facts, these investments are viewed as critical to capitalizing on future supply gaps despite immediate liquidity pressures.
