SEMAFO Confirms Continuity of Mineralization at Mana's Kona Zone Delineation Drilling Results Include 4.44 g/t Au Over 21 Meters

MONTREAL, QUEBEC--(Marketwire - Sept. 9, 2010) - SEMAFO (TSX:SMF) today announced results from its delineation reverse-circulation ("RC") drilling program on the Kona Zone confirming the continuity of the mineralization at the Company's Mana Mine in Burkina Faso. The Kona Zone is located immediately northeast and on-strike with the Wona open pit.

Reverse-circulation drill holes MRC10-136 to MRC10-171 cover the Kona mineralization over a strike length of one kilometer, using 50-meter interval spacing. Results confirm the continuity of the mineralization over the entire strike length with local wide and higher grade intervals including 4.44 g/t Au (5.83 g/t uncut) across 21 meters. These results will be included to the resource estimation and the economic portion in the mine plan.

The delineation drilling program includes 36 RC holes totaling 5,380 meters (holes MRC10-136 to MRC10- 171).

Recent drilling focused on delineating previously identified potential to upgrade the resource category, with additional potential still to be investigated further to the northeast as well at depth (Figure 1). Hole MRC10-026 drilled earlier this year on section 19100 N (northeast of the delineated section of the zone) returned 2.89 g/t Au across 3 meters. This interval suggests that the gold bearing Wona Corridor continues past the delineated zone with the potential to identify additional resources.

The parallel zones associated with the Kona Zone also returned significant results, particularly in the southwest part of the drilled area. The proximity of these zones to the main structure will undoubtedly add to the Kona Zone resource base.

The exploration programs were designed and managed locally by Dofinta Bondé and David Lalonde, Mana Mineral's Exploration Chief Geologists and Richard Roy P Geo, Deputy Geology Manager, and guided and supervised under the direction of Michel Crevier, P.Geo MScA, Geology Manager and SEMAFO's Qualified Person who has reviewed this press release for accuracy and compliance with National Instrument 43-101.

All individual samples represent approximately one-meter in length of rock chips homogenized and riffle-split to an approximately 2-kilogram sub-sample, which is sent for preparation and gold assaying at the ALS Chemex laboratories in Ouagadougou, Burkina Faso. Each sample is fire-assayed for gold content on a 50-gram sub- sample at the same ALS Minerals laboratories. In addition to ALS Minerals' own QA/QC (Quality Assurance/Quality Control) program, an internal quality control and quality assurance program is in place throughout the sampling program, using blind duplicates, blanks and recognized industry standards.
