Copper demand is set to surge in the coming decades. According to BHP’s recent report, "How Copper Will Shape Our Future" (September 30, 2024), global demand is projected to rise by an astonishing 22.1 million metric tons (Mt) between 2021 and 2050—a 70% increase. This visual underscores the immense scale of new supply required to meet this demand.
To put it into perspective, the world’s largest copper mine, Escondida in Chile, has a maximum production capacity of 1.35 Mt annually. Meeting the 22.1 Mt demand increase would require the equivalent of 16.37 new Escondida-sized mines operating at full capacity—on top of maintaining current global production levels. However, such discoveries are exceedingly rare, and a recent S&P Global report highlights the significant decline in large copper discoveries, reducing the likelihood of bringing mines of that scale online anytime soon.
Adding to this challenge is the increasing lead time for bringing discoveries into production. For mines that commenced production between 2020 and 2023, the average lead time jumped to 17.9 years (source). This delay is driven by longer exploration, permitting, and study phases, as well as extended periods between the completion of feasibility studies and the start of construction. Much of this can be attributed to the time required to secure financing and construction permits.
The combination of declining discoveries and longer development timelines presents a significant challenge for the copper sector's ability to meet the projected demand surge by 2050. Addressing this gap will require innovative solutions, significant investment, and perhaps a rethinking of how the industry operates.
