Critical Minerals Geopolitics and Corporate Strategy

Critical minerals remained the dominant mining topic in May 2026

Governments across North America, Europe, Australia and Asia intensified efforts to secure domestic supplies of critical minerals, particularly rare earths, lithium, graphite, copper and nickel. The topic consistently ranked among the most discussed mining themes globally as governments increasingly view mineral supply chains as a matter of national security.
