SEMAFO Diamond Drilling Program Successfully Expands Wona Mineralisation
At-Depth

SEMAFO TSX-SMF

MONTREAL, Sept. 14 /CNW Telbec/ - SEMAFO (TSX: SMF) today announced its most recent drilling results which demonstrate a significant high-grade lode just below the bottom of the Wona North pit at the Mana Mine in Burkina Faso.

The Company's 2009 exploration program at Mana began in April. As at August 31, a total of 18,342 meters of drilling have been completed; drill holes WDC 80 up to WDC 129, which remains in progress. Meanwhile, assays results have been received up to hole WDC 116.

The current drilling program confirms the NE at-depth high-grade extension of the Wona zone. Initial reference to this potential mineralization was made in SEMAFO's press release dated March 24, 2008, while further updates were released on June 17, June 30, and August 8, 2008 as well as those published February 25, March 2, June 30 and August 10, 2009.

Recent drilling results not only support the presence of significant mineralized zones at-depth, but some holes significantly extend the lateral and depth of the mineralized zones. Hole WDC 106 extends the main recognized lode at-depth, while holes WDC 102 and WDC 104 confirm the continuity of the strong mineralization from the Wona main pit on-surface towards its known 25-degree plunge. Mining studies are currently planned in order to determine the optimal mining approach to this portion of the deposit. Holes WDC 105 and WDC 108 suggest the presence of a second parallel lode below and to the south. Also of importance is hole WDC 115 which supports the interpreted re-swelling of the main ore-shoot along the plunge, past an apparent pinch in the mineralization. The presence of higher grade internal intervals within the section offers optimism to add significant mineralization at-depth. Hole WDC 115 is the deepest hole drilled to date along the plunge direction. Follow up drilling is scheduled over the most promising areas for expansion.

Detailed geological descriptions of the diamond drill core have highlighted a strongly sericitized and carbonatized host rock associated with the mineralization. Moreover, a spatial relationship was recognized between the silicified mineralized zones and intrusive dykes of various compositions. The anisotropy caused by these intrusives is believed to have channeled the mineralizing fluids. Significant intensity of fracturing could have been generated by the difference in competency between the intrusive dykes and the host rocks.

The following table presents the drill results including the main mineralized intersections and high-grade values.

The drill holes described above are presented on the attached longitudinal section (http://files.newswire.ca/357/section.doc) displaying contoured grade-thickness product. The longitudinal schematic shows the mineralization trend along with previously reported drill holes and upcoming targets to be tested.

The drilling programs were designed and managed locally by Dofinta Bondé, Mana Mineral's Exploration Chief Geologist, supported by Donald Trudel, experienced mine and exploration professional geologist, 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 core which was sawn in half. Half of the core is kept on site for reference and its counterpart 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 Chemex laboratories. In addition to ALS Chemex's 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.

Mana has a total of 908,600 ounces of gold mineral reserves, 1,021,400 ounces of measured and indicated resources and 508,200 ounces of inferred resources as at December 31, 2008.
