OUAGADOUGOU -- The last two dead bodies of miners missing from a Burkina Faso zinc mine owned by B.C.'s Trevali Mining corp that flooded on April 16 were discovered on Wednesday, the government said in a statement.

Hopes of finding any survivors vanished last month when rescue teams found no one inside a refuge chamber in which there was a slim chance the eight miners might have sought shelter.

The Perkoa mine was flooded after torrential rain fell unexpectedly during the West African country's dry season. Four bodies were found on May 24 and another two four days later. 

Both the government and Canada-based Trevali have opened investigations into the incident. 

The eight victims were six Burkina Faso nationals, one Tanzanian and one Zambian.
