Results from the RC infill drilling on the Kona open-pit area are concordant with the current magnitude of reserves and resources, with a potential slight gain in the northern area.The exploration programs were designed and managed locally by Dofinta Bondé and David Legault, Mana Mineral's Exploration Chief Geologists, David Lalonde, Deputy Exploration Manager, and Richard Roy P Geo, Exploration Manager, and guided and supervised under the direction of Michel Crevier, P.Geo MScA, Vice-President, Exploration and Mine Geology and SEMAFO's Qualified Person who has reviewed this press release for accuracy and compliance with National Instrument 43-101.All individual RC 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 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.About SEMAFO SEMAFO is a Canadian-based mining company with gold production and exploration activities in West Africa.
