Chile Copper Output Falls to Nine-Year Low as Ore Grades Decline

Chile copper production dropped to 378,554 metric tons in February 2026, according to data published Tuesday by the national statistics agency INE. The figure represents an 8.5% decline from January’s 413,712 tons and a 4.8% year-over-year contraction — the seventh consecutive month of annual declines.

The last time Chile posted a lower monthly total was March 2017, when a major strike shut down BHP’s Escondida, the world’s largest copper mine. No comparable disruption occurred in February 2026 — this decline reflects structural factors, not one-off events.

Why Output Is Falling

The primary driver is declining ore grades across Chile’s major deposits. Mines are extracting copper from increasingly lower-quality rock, requiring more energy, water, and processing per ton of output. Glencore reported an 11% drop in its 2025 copper production, with its Collahuasi mine in Chile accounting for 68,100 tons of lost output due to lower head grades as the operation transitions to the Rosario pit.

Key expansion projects have also underperformed. Teck Resources’ Quebrada Blanca mine, one of Chile’s most important growth assets, has been battling waste-storage issues and delayed optimization work. Teck cut its 2026 production forecast to 200,000-235,000 tons, down from an earlier estimate of 280,000-310,000 tons.

Seasonal factors added pressure in February: summer rainfall in northern Chile and heavy ocean swells disrupted logistics at port facilities. But these are temporary — the grade decline and project delays are not.

Global Supply Implications

Chile produces approximately one-quarter of the world’s mined copper. When the largest supplier contracts, the global market tightens — and this is happening against a backdrop of surging demand from the energy transition. Copper is essential for solar panels, wind turbines, electric vehicles, battery storage, and the grid infrastructure connecting them all.

The supply constraints helped push copper prices to record highs in January before moderating in February and retreating further during the Iran conflict. The national mining association Sonami has set 2026 production guidance at 5.5-5.7 million metric tons, but the February data raises questions about whether even the lower end is achievable.

BHP’s $5.15 Billion Bet on Escondida

The industry’s response to declining grades requires massive capital. BHP recently presented a $5.15 billion project to sustain production at Escondida, its flagship Chilean mine. State-owned Codelco is targeting 1.344 million tons in 2026 while executing over $40 billion in structural projects across Chuquicamata, El Teniente, Rajo Inca, and Andina.

Chile has delayed its goal of reaching peak annual production of 6 million metric tons by several years. The country’s $14.8 billion copper project pipeline scheduled for 2026 commissioning phases represents the critical bridge between current decline and future recovery.

What It Means for Markets

Industry analysts estimate that the global copper supply gap could reach 7.7 million tons annually by 2034. Roughly half of the additional supply needed is expected to come from South America, with Chile leading. At current trajectory, Chile risks falling short of its role as the primary gap-filler for the energy transition’s most critical industrial metal.

Under President Kast’s new administration, Chile has signaled a pivot toward the United States on minerals cooperation and faster permitting. Whether that translates into production gains before the decade’s end will determine not just Chile’s fiscal trajectory but the pace of the global energy transition itself.
