BOGOTA – One miner died and another remains missing after inhaling toxic gases at a gold mine in Risaralda, a province in west-central Colombia, emergency services officials said.

The miners were working inside the La Amapola mine in a rural area outside the town of Quinchia when the accident occurred.

The two miners were apparently overcome by toxic fumes, fire chief Jesus Antonio Velez Villada said.

Firefighters from several towns near Quinchia are working to find the missing miner, whose condition is not known.

The La Amapola mine is between the towns of Irra and La Felisa on the shores of the Cauca River, near Risaralda’s border with neighboring Caldas province, and some 300 kilometers (186 miles) west of Bogota. EFE
