Trevali increases pumping capacity as it searches for missing Perkoa workers

Canada-based Trevali Mining said on Monday that it was continuing dewatering efforts at Perkoa in its search for eight workers that went missing when the mine flooded on April 16.

The company has a three-stage dewatering plan, of which the first two stages – the repurposing of existing piping to start initial dewatering efforts, followed by the installation of additional underground pumping infrastructure to facilitate an increase in pumping capacity – are now complete and actively pumping. The third stage, which is currently in progress, involves the installation of 5 000 m of new piping and higher-capacity pumps to increase pumping capacity.
