A group of tourists visiting an old 1890s gold mine in Colorado, which has now been turned into a tourist attraction, ended in tragedy.

The incident occurred at the Mollie Kathleen gold mine in Cripple Creek, from a “mechanical failure” in an elevator that was transporting the group of visitors to a 300-metre-deep gallery.

One person was killed and 4 were injured in the accident, while another 11 people were immediately rescued.

But 12 tourists remained trapped for hours 300 meters underground, until rescuers finally managed to free them.

Rescuers reported that they had been in contact with them, assuring that the trapped people had water and blankets with them.

Colorado Governor Jared Polis announced a while ago that the 11 tourists and their tour guide had been rescued.

Teller County Sheriff Jason Michaels confirmed to reporters that there was one person dead, without specifying the exact cause of death.

The Mollie Kathleen Gold Mine in Cripple Creek, Colorado. It is an 1890 gold mine located 80 kilometers from the city of Colorado Springs. It has become an attraction for tourists, who are guided through the underground galleries and informed about its history.
