A miner is missing after a cave-in at an underground gold mine near Winnemucca, Nevada.

A spokesman for the Mine Health and Safety Administration says two mine rescue teams were sent to the scene of the cave-in, which happened early Tuesday morning at the underground Getchell Mine.

Spokesman Dirk Fillpot says one miner is believed to be trapped in the accident.

He says the miner was reported to have been working on a roof bolter when the ground shifted and buried the heavy machinery.

There's no word on how far below the surface the accident occurred.

The Getchell Mine is owned jointly by Toronto-based Barrick Gold Corp. and Denver-based Newmont Mining Corp.

It is operated by SMD, an independent contractor.

Barrick spokesman Vincent Borg says the missing worker is an employee of SMD.
