The regional coroner's office has identified the worker killed at a talc mine early Wednesday near Madoc, Ont.

Regional coroner Dr. Peter Clark says Justin Rogers, 22, of Madoc, died of asphyxiation in the incident shortly before 2 a.m. at the Canada Talc mine.

A spokesman for the Ministry of Labour, which is investigating along with the coroner and police, says Rogers was filling a skip with material when it began to slide on its own, engulfing him.

Police say the accident happened about 200 metres below ground where talc is elevated to be crushed and refined.

An inquest into Roger's death will follow the investigation, as mandated by the Ontario Coroners Act.

The company's website indicates that approximately 50 employees work at the mine, which generates between $1 million and $5 million in sales.
