Landslide at Oyu Tolgoi copper mine in Mongolia injures 15 workers

A rock burst injuring 15 workers at Oyu Tolgoi is a reminder that the copper supply story rests on geology as much as demand. The mine is one of the largest known copper-gold deposits and a key growth asset for global copper supply, so any disruption to underground operations carries weight for the refined copper market and for the miners and smelters tied to its output. No fatalities were reported, which limits the immediate operational read-through; whether the incident prompts a review of underground ground-control practices, and whether output guidance is affected, is the open question.
