Central Chile's severe frontal system disrupts mining operations and threatens worker safety

A powerful weather front that swept central Chile brought intense rain, snow and high winds to the Biobío, Coquimbo and Atacama regions. The storm forced the suspension of many mining activities and left more than 1,000 workers isolated in remote cordilleran sites, prompting emergency protocols from companies such as Los Pelambres. The firm reported that its mine, plant, Tranque El Mauro and port remained operational, but access roads and power supplies were heavily affected. In response, Los Pelambres activated its controlled‑evacuation system, provided shelter, food, heating and health care for personnel, and supplied emergency kits to nearby communities.

Labor authorities warned employers to protect employees under the emergency, stating that work must stop where basic services like water are unavailable. Legal experts clarified that a meteorological alert does not automatically excuse attendance unless conditions make travel dangerous or impossible. The Dirección del Trabajo pledged inspections and urged tolerance for workers unable to reach their jobs.

The storm also caused fatal incidents, including the death of a rural worker swept away by the swollen Copiapó River, adding to the region’s toll. Health services faced criticism for lacking a clear contingency plan, leaving staff exposed to flooding and power cuts. Across the affected zones, authorities continue to monitor river levels, road conditions and infrastructure stability as the front moves inland.
