SEMAFO Reports Significant Results from its Wona Extension Deep Drilling Program

    Important Gold Values Include 27 Meters at 6.08 g/t


    MONTREAL, Aug. 10 /CNW Telbec/ - SEMAFO (TSX: SMF) today announced its
most recent drilling results that include one of the highest grade intercepts
recorded to date (WDC99: 6.08 g/t / 27.2 m). The drilling results suggest a
significant high grade lode just below the bottom of the planned Wona North
pit at the Mana gold mine in Burkina Faso.
    As part of the Company's 2009 exploration program at Mana, core drilling
is ongoing and intensified with the addition of a third drilling rig on July
20. At the end of July, 31 drill holes were completed representing
approximately 11,640 meters. New assays results have been received for holes
WDC 93 to WDC 99.
    The current drilling program confirms the at-depth NE high-grade
extension of Wona. Initial reference was made to this potential mineralization
in SEMAFO's press releases dated February 25, March 2, and June 30, 2009 as
well as those published March 24, June 17 and August 8, 2008. Results maintain
the presence of significant mineralized zones at-depth.
    The area herein described is shown on the attached longitudinal section
displaying contoured grade-thickness product with hole location.
    The following table presents the drilling results including the main
mineralization intersected and high-grade values.

    The following schematized longitudinal shows the mineralization trend
with the past drilling and indicates upcoming programs.

    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 the Canadian Instrument NI 43-101.
    All individual samples represented one-meter length of core drilling
which was sawn in half or one-meter length. One-half core is kept on site as a
control with the identical sample sent for preparation and gold assaying at
the ALS Chemex laboratories in Ouagadougou, Burkina Faso. Each sample was fire
assayed for gold content on a 50-gram sub-sample at the same ALS Chemex
laboratories. Complementing ALS Chemex's own QA/QC (Quality Assurance/Quality
Control) program, an internal quality control and quality assurance program
was in place throughout the sampling program, using blind duplicates and
recognized industry standards.
    As at December 31, 2008, Mana had 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.
