The mining area has become unsafe for SEMAFO, which is in control of two gold mines in Burkina Faso.
Geodrill Limited ("Geodrill" or the "Company") (GEO.TO), regrets to report two of its employees have been fatally wounded in a terrorist attack between Fada and Boungou in Est Region, Burkina Faso.
Five buses carrying Semafo, Perenti and African Mining Services employees, contractors and suppliers were travelling with military escort when they came under attack.
Company president and CEO Benoit Desmormeaux sympathised with the families and colleagues of the 37 people who were killed in the attack on the public road about 40 km from the mine site.
Although the Boungou mine site was secure, Semafo suspended operations out of respect to the victims and those impacted, Desmormeaux added. Last year, an employee and subcontractor died after a bus was targeted by bandits, according to Canadian Press.
A security source said "a military vehicle that was escorting the convoy hit an explosive device".
But in a presentation of securities this week in Canada, the Montreal-based company, Semafo, characterized two attacks against its workers in Burkina Faso previous year "as part of an increase in similar incidents carried out by bandits or terrorists".
The government this year asked mining companies to make their own arrangements to transport employees, sources close to the miners said.
The Canadian government also condemned the attack.
Increased bloodshed has forced hundreds-of-thousands of people to flee their homes, igniting a fast-growing humanitarian crisis.
Wednesday's attack was the worst since groups with links to Islamic State and al Qaeda began targeting the landlocked nation with high-profile attacks in January 2016.
The country's badly equipped, poorly trained and underfunded security forces have been unable to stem the violence, which has intensified throughout 2019 to become nearly daily.
The Boungou mine is located in Burkina Faso's Eastern region about 355 km (220 miles) from Ouagadougou.
