Codelco Lowers Its Copper Output Forecast

Codelco lowered its copper production outlook, according to chairman Bernardo Fontaine's shareholder-meeting remarks reported by Reuters on November 5, 2026. It now expects slightly more than 1.2 million metric tonnes in 2026, down from a previous target of 1.34 million tonnes. For copper holders, the lower forecast reduces the production we can expect from one of the industry's largest suppliers this year. It also gives us a new operating development to assess alongside the investigation into historical reporting.

How much copper should we remove from our supply assumptions? The new forecast is approximate, so an exact tonnage reduction would give it precision Fontaine's wording does not support. We can say that Codelco expects less production than its previous target. We cannot turn that forecast change into a quantified shortfall in customer deliveries, because the report provides no corresponding shipment revision. If you own copper miners for exposure to constrained supply, the lower production expectation supports that case, while leaving the actual delivery effect unresolved.

Separately, Reuters reports a 42,100-tonne output reporting error across 2024 and 2025. Codelco's November 5 shareholder-meeting release describes the investigation's figures as preliminary and says they could change as audits continue. That qualification belongs beside the historical correction. Adding it to the reduction in this year's forecast would mix different periods and exaggerate what today's announcement establishes about new supply losses. We should revise our expectations for current production and our understanding of past production separately.

The company's accompanying tables show why the distinction is necessary. Its misinventoried-material table, published November 5, lists material declared as production even though it was incorrectly classified in inventory. Its duplicate-production and timing table from the same release includes both duplicated output and production reported before it occurred. An early recognition that reverses in the following year has a different effect from a duplicate entry. The release's narrative annual figures do not fully reconcile with its table subtotals, which is another reason to keep the historical adjustment provisional until the audits settle it.

In Chile Expects Codelco Audit Within Two Months, we focused on the timetable for checking past output. The new forecast gives us a separate reason to assess how much production the market can expect now. For your copper exposure, reduced expected output from Codelco can strengthen the case for producers that deliver their own plans. The risk is paying for a shortage before production, inventory and shipment figures establish its size. We would keep the historical audit findings and current operating performance separate when judging the shares you own.

Our checkpoint is December 31, 2026: by year-end, we will look for updated production and delivery figures, alongside any completed audit reconciliation, without assuming Codelco has promised an audit publication by then.

Seek the truth and be prepared,
