HERRIMAN — A Kennecott Utah Copper employee is recovering Sunday after a rollover accident.

The victim, who has not been identified, was driving a haul truck filled with ore from the mine to a disposal site when the truck rolled.

"This is very uncommon," said Kyle Bennett, Kennecott spokesman. "I've only heard of one other time this has happened, so we're very concerned about it. It's something we are going to look at and prevent from every happening again."

The victim was taken to University Hospital in stable condition, officials said.
