Codelco postpones Andes Norte project until 2029
Codelco has formally postponed the Andes Norte project at the El Teniente mine until at least 2029. This delay follows the detection of an unprecedented seismic anomaly on August 4, 2026.
The postponement poses a significant impact on production, with a potential loss of up to 450,000 tons of copper annually. As one of the most critical expansion initiatives for the world’s largest underground copper mine, the delay highlights ongoing structural challenges facing the Chilean state-owned mining company.
