One person was killed and officials were working to rescue 12 others trapped deep beneath the surface of a former Colorado gold mine after an elevator malfunctioned at the tourist site, authorities said Thursday.

The elevator descending into the Mollie Kathleen Gold Mine near the town of Cripple Creek had a mechanical problem around 500 feet (152 metres) beneath the surface, creating a "severe danger for the participants" and one person was killed, Teller County Sheriff Jason Mikesell said at a press conference.

Twelve people were still at the bottom of the mine, about 1,000 feet (305 metres) beneath the surface. They were safe and in communication with authorities, said Mikesell. Rescuers were working to get the elevator back online.

The elevator accident was reported to authorities at about noon, the sheriff said. He declined to identify the victim or say how they died. Two children were involved but it was unclear if they were among those who were trapped.

Eleven people who were riding the elevator were rescued, Mikesell said. Four had minor injuries. The sheriff did not elaborate on how they were injured or the nature of the elevator's mechanical problems.

The sheriff said authorities could rescue the trapped group by rope if necessary, but were hoping to get the elevator system safely working and to resolve the situation Thursday night.

"We want to inspect it, make sure it's safe before bringing them back up with it," Mikesell said. "We do have a plan B and a plan C already set in place with rescue officers."
