Two missing miners were feared to be dead in an accident Thursday at an underground gold mine that has seen three fatalities over the past 11 years.
Barrick Gold Corp. has not confirmed any deaths at the Meikle mine, but a company official referred to the search as a "recovery effort" directed by the U.S. Mine Safety and Health Administration.
"While we don't have all of the facts at this point, what we do know about the incident is not encouraging," said Greg Lang, president of Barrick's North America Region.
Lang said the initial investigation was focused on a hoist in the ventilation shaft of the mine, which is about 55 miles northwest of Elko and 275 miles northeast of Reno.
An official for MSHA in Washington D.C. told The Associated Press that two workers were being lowered into the shaft when the hoist operator noticed a "large surge of pressure on the hoist drum and the mine was evacuated."
The workers "have not been located," said the official, who was not authorized to disclose the information publicly and spoke on the condition of anonymity.
The accident occurred about 1:15 a.m. at the mine with about 300 workers. The Toronto-based company Barrick notified the missing miners' families Thursday and shut down the mine's underground operations, Lang said.
The Meikle mine, operated by its subsidiary Barrick Goldstrike Mines, has had three deaths in three separate accidents since 1999, according to MSHA records. The most recent was in August 2004 when a truck driver was pinned between his truck and a cement pillar. Another truck driver was killed in February 2000 when he backed his water truck into an open slope, was ejected and fell 75 feet below.
In April 1999, a miner was cleaning debris from a rock blasting area, lost his footing and fell into an opening about 150 feet to his death, the MSHA records show.
Barrick, the largest gold company in the world, owns several mines in Nevada — the fourth largest producer of gold in the world behind South Africa, Australia and China.
