Sources: 5. Developments: 2. Codelco’s El Teniente division has implemented several initiatives focused on operational efficiency and technological advancement. In early August, the division launched a Digital Operational Intelligence Unit. This unit consolidates data from over 6,000 sensors and 60 databases to create predictive models and AI tools. According to division leaders Branco Espinosa and Juan Orellana, the system is designed to improve safety, productivity, and operational continuity by providing actionable insights and reducing manual tasks. Later in the month, the division completed a refurbishment project for four decommissioned railway ore transport cars that had been out of service for approximately five years. The project involved technical upgrades to pneumatic, hydraulic, and braking systems, as well as applying an anti-adhesive polymer film to prevent mineral buildup. The refurbishment cost the equivalent of a single new unit, representing a significant cost saving for the operation. ## Timeline ### 2026-08-31: Codelco El Teniente recovers four decommissioned railway ore cars Codelco's El Teniente division has refurbished four railway ore cars that were out of service for five years, achieving significant cost savings compared to purchasing new equipment. 5 sources. https://clstr.news/cluster/codelco-el-teniente-recovers-four-decommissioned-railway-ore-cars ### 2026-08-06: Codelco's El Teniente launches digital intelligence hub to boost mining safety and efficiency Codelco’s El Teniente mine has built a Digital Operational Intelligence Unit that integrates sensor and database feeds into AI‑driven tools, enhancing safety, efficiency and decision‑making across operations. 2 sources. https://clstr.news/cluster/codelcos-el-teniente-launches-digital-intelligence-hub-to-boost-mining-safety-and-efficiency --- Cite as: Codelco El Teniente operational improvements.
