The case has caused outrage in the country, as rescue operations only got under way following protests and a sit-in at a government building five days after the floods.
Perkoa mine, owned by Canadian firm Trevali Mining Corp and located about 120km (75 miles) west of the capital Ouagadougou, was abruptly submerged on April 16 after torrential rain fell unexpectedly during the country’s dry season.
