Two miners were killed and 19 injured in an accident at the Revenue-Virginius Mine south of Ouray Sunday morning, according to the Ouray County Sheriff's Office.
The incident was reported at about 7:20 a.m.
Killed were Nick Cappanno, 34, of Montrose, and Rick Williams, 59, of Durango. Williams, a former resident of Silverton, was a 1972 graduate of Silverton High School.
Cause of death has been ruled carbon monoxide poisoning.
At least two Silverton miners were among the injured — Ken Jenkins, 53, and Mike Luther, 58.
Luther was released from Montrose Memorial Hospital on Monday.
At least a dozen Silverton residents work at the Revenue-Virginius Mine, which reopened last year. Stabilization work on the old mine has been in process ever since. The mine received a conditional permit in February. Since then about 100 workers have been putting in three shifts, constructing dry room facilities and rehabilitating tunnels.
Ouray County officials reported that 19 people were taken to various hospitals in the region. Nine people were transported by ambulance to Montrose Memorial; five persons were transported to Delta Memorial Hospital; and five people were taken to St. Mary’s Hospital in Grand Junction.
Cappanno and Williams, who were trapped underground, were later confirmed dead.
Federal mine safety officials are investigating the accident. One question is whether a blast or drilling on Saturday may have played a role in releasing deadly gases underground.
