Mining and metals companies today must contend with various geopolitical risks, supply chain risks, and target-market risks, but many do so from a strong financial position. For their companies to thrive in this decade, mining CEOs must think holistically and establish a plan-ahead team, focusing on the factors associated with value creation.
