SEMAFO Mourns Passing of Board Chairman Jean Lamarre

Montreal, Quebec, November 23, 2017 - Semafo (TSX, OMX: SMF) announces with sadness the passing of Mr. Jean Lamarre, Chairman of the Board of Directors of the Corporation, on November 22, 2017 following a short illness. Mr. Lamarre joined the Corporation's Board of Directors in 1997 and was appointed Chairman of the Board in 2000, a position he held until his demise.

"Jean made an indelible mark on SEMAFO, both in terms of his corporate governance expertise and his 45 years of experience in Africa," said President and CEO Benoit Desormeaux. "Over his 20-year tenure with SEMAFO, he brought unique insight, business acumen and leadership to the Corporation as it transitioned from an exploration company to a junior Gold producer. He did this, always without compromising his values: the integrity of the Corporation, his deep love for Africa and its people, and his priority to SEMAFO's long-term sustainability. On behalf of SEMAFO's Board of Directors, management and employees, I express our deepest condolences to Jean's wife and family and our gratitude to an exceptional man. He will be sorely missed."
