South America’s copper boom faces a $170B reality check

Mining consultants warn that investment pledges, permitting reforms and ambitious targets may not translate into output.

Ambitious copper investment plans across the Andes could fail to deliver the production growth governments expect unless miners overcome financing, infrastructure and operational bottlenecks, according to GEM Mining Consulting.

Peru’s 2026 mining portfolio includes 66 projects worth an estimated $64.1 billion, while Chile’s investment pipeline totals $104.5 billion for 2025–2034.

Argentina could also benefit from a US Export-Import Bank financing framework intended to mobilize up to $7 billion through 2027.

“Copper announced is not copper delivered,” GEM said in its report, arguing that investment commitments and production forecasts offer little assurance of how much metal will ultimately reach customers.

The warning comes as the International Energy Agency’s 2026 base-case mine pipeline points to an approximately 25% shortfall against projected primary copper requirements by 2035 under its Stated Policies Scenario.

The estimate accounts for secondary supply and refining losses, underscoring the importance of bringing new mines into production.

Yet GEM cautions that the scale of announced investment can obscure a fundamental distinction between maintaining existing operations and generating additional output.

Much of its mining investment portfolio involves brownfield projects designed to sustain production, replace declining capacity or expand existing operations.
