The race to reach eight workers trapped in a flooded, Canadian-owned zinc mine in West Africa is making progress. Trevali Mining Corp. says access to its Perkoa Mine in Burkina Faso is improving after more than 32 million litres of water were pumped out of the shaft.
Workers became trapped more than 500 metres below the surface on April 16, after heavy rain caused flash flooding which breached two embankments outside the mine, said Trevali in a statement to CBC News on Tuesday. Sixteen other workers underground at the time were able to escape.
