Rescue teams pumping water from a flooded Burkina Faso zinc mine in which eight workers have been trapped for almost a month are drawing closer to a refuge chamber where they may have sought safety, the government said on Wednesday.
The six Burkina Faso nationals, one Tanzanian, and one Zambian, have been missing since heavy rainfall caused flash floods at Canada-based Trevali Mining Corp's Perkoa mine on April 16, forcing it to suspend operations.
The company said that while most workers underground were able to safely evacuate, the eight missing were below Level 520, which is 520 metres (1,706 feet) from the surface, at the time of the flooding.
