An accident at a mine in Colorado on Sunday injured at least 20 people and left two miners trapped underground, the state’s emergency management office said.
One of those injured was in critical condition at Montrose Memorial Hospital, according to Micki Trost, the public information officer for the state’s Division of Homeland Security and Emergency Management.
“A rescue is currently underway for two miners who remain underground but accessible,” Trost said, adding that the conditions of the miners were not known.
The accident — details of which were not immediately known — occurred at the Revenue-Virginius mine near Ouray.
The mine produces silver, lead, zinc, copper and gold, according to the company website.
