At the height of the frenzy in 2013 the combined capital expenditure of the world's 40 largest mining firms by market value reached $130bn, according to pwc, an advisory firm, nearly four-fifths of their earnings before interest, tax, depreciation and amortisation (EBITDA). That spending spree left mining bosses redfaced as economic growth in China slowed, causing commodity prices and the industry's profits-to plummet.
Miners spent the years that followed cleaning up the mess.
In 2015 more than $50bnworth of assets were written down. BHP, the world's most valuable mining firm, spun off its least-loved sites to raise money and simplify its sprawling business. Others followed suit. Cash was used to pay off debts instead of financing new projects. Since then, profits and commodity prices have recovered. But investment has not. In 2022 the 40 largest miners together invested $75bn, equivalent to a mere quarter of EBITDA (see chart 1). BHP, which on February 20th reports its results for the second half of 2023, invested some $7bn last year, analysts reckon a third as much as it spent in 2013.
That is a problem. Decarbonising the global economy will require 6.5bn tonnes of metal between now and 2050, according to the Energy Transitions Commission, a thinktank. Although much attention has been paid to the lithium and nickel needed for batteries, that is only one part of the picture. Fully 170m tonnes a year of steel, comprising mostly iron ore, will be needed for everything from wind turbines to electric vehicles (EVS) more than ten times current global production.
Vast amounts of copper will be required to expand and upgrade electricity grids.
