A Perkoa mine manager was given a 24-month suspended sentence, while a manager from Trevali's contractor Byrnecut was given a 12-month suspended sentence, said Ditil Moussa Palenfo, country director of Nantou Mining, the Trevali entity that owns Perkoa.
Relatives of some of the victims in April had filed a complaint for involuntary homicide, causing danger to life and failure to help people in danger. Burkina Faso's prime minister said that the managers were banned from leaving the country while investigations were underway.
Eight miners drowned in the underground passages of Trevali's Perkoa zinc mine in Sanguie province after torrential rain fell unexpectedly during the West African country's dry season.
The last body was recovered in June after 66 days of searching.
There had initially been hope the missing miners had reached a refuge chamber located around 570 meters below ground. But it was found empty one month later.
Both the government and Trevali, which says it was caught off-guard by the flood, have opened investigations into the incident.
