SANTIAGO (Reuters) -Chile's mining regulator Sernageomin said on Friday it is investigating the death of a worker at BHP's Escondida, the world's largest copper mine.

Two sources with knowledge of the matter said mining operations continued normally after the incident.

BHP in a statement said a contractor had died on Thursday. An internal memo from Chilean construction company Workmate described the worker as a crane operator at Escondida.
