Thirteen killed in collapse at illegal Colombian gold mine

A deadly landslide has struck an illegal gold mining site in Colombia's southwestern Nariño department, leaving at least 13 workers dead and seven injured. The slope collapse occurred while mining operations were underway at the unlicensed facility, burying workers beneath tons of rock and soil.

Rescue and emergency response teams were deployed to the site following the disaster. The exact circumstances surrounding the collapse are still under investigation, though authorities have indicated that the mining activity itself contributed to destabilizing the slope.

The incident underscores the hazardous conditions facing workers at informal and illegal mining operations across South America. Such sites frequently lack proper safety measures, geological assessments, and regulatory oversight, making them particularly vulnerable to accidents.

Illegal gold mining remains a significant problem in Colombia, particularly in remote and mountainous regions where enforcement is challenging. The activity has been linked not only to workplace fatalities but also to environmental degradation and funding of criminal organizations. Authorities in Nariño have indicated they will investigate the incident and take action against those operating the unlicensed mine.
