SEMAFO Announces Q2 2017 Production Montreal, Q

Montreal, Quebec, July 6, 2017 - SEMAFO Inc. (TSX, OMX: SMF) today announced that gold production for the three-month period ended June 30, 2017 totalled 47,600 ounces of gold. The Mana Mine processed 675,500 tonnes at an average grade of 2.31 g/t Au in the quarter, including 194,100 tonnes of low-grade material at an average grade of 0.72 g/t Au.

*Production numbers are preliminary and subject to final adjustment.

RC Grade Control Ongoing at Siou Following geological interpretation issues in the upper portion of Zone 9 earlier this year, the Corporation has changed its method of grade control from channel sampling to reverse-circulation (RC) drilling. In-pit RC drilling commenced at the end of May and is being conducted to a vertical depth of up to 30 meters. In early August, we will be in a position to disclose the grade control results compared to the H2 2017 mining plan for Zone 9.

In light of the above, the Corporation is confident that Zone 9, which hosts the widest, gold-rich structure of Siou's mineral reserves, remains high-grade. The Corporation reiterates its 2017 production guidance of between 190,000 and 205,000 ounces of gold and its all-in sustaining cost guidance of between $920 and $960 per ounce.

Conference Call The Corporation will hold a conference call on Wednesday, August 9 to discuss its second quarter 2017 results. Interested parties are invited to join the call and webcast at 10 a.m. EDT.
