Semafo reports definition drilling results on Mana Nyafe deposit

    SEMAFO TSX-SMF

    MONTREAL, Nov. 20 /CNW Telbec/ - SEMAFO (TSX - SMF) today announced
definition drilling results for the Mana Gold project, Burkina Faso.
    Located within the Houndé volcano-sedimentary belt, which is known for
its gold mineralization potential, the Mana gold project currently holds two
important gold deposits, namely the Wona and Nyafe deposits, both deposits are
hosted in a volcano-sedimentary belt extending in a north-east direction.
Specifically, the Wona deposit sits essentially in meta-sediments consisting
of large mineralization, where as the Nyafe deposit is composed of high-grade,
narrow structures hosted in sheared volcanic rocks.
    Over the past months, definition drilling programs have been carried out
at Nyafe, and have confirmed ore already identified in previous works. The
2007 RC drilling program objective has been the formal definition of the
entire deposit, according to guidelines of the 43-101 Standard. This follows
up on core drilling carried out in late 2006 in order to enhance the level of
geological understanding of the Nyafe ore body. Both core and RC drilling was
executed by Boart Longyear. Works to identify more lenses of the Nyafe
structure is under way.
    RC drilling to date on the Nyafe deposit amounts to 238 holes, most of
which have intersected economic gold mineralization, Results feature widths
varying up to 14m and gold grade up to 23g/t. Highlights of these works are
presented in the table below. The results will be incorporated into the next
update of gold reserves to be prepared during the first quarter of 2008.

    Note:   The table above summarizes intercepts based on a minimum of three
            meters grading three grams per tonne.

            All lengths are downhole lengths; additional information is
            required to determine true widths.
    

    The drilling programs were designed and managed locally by François
Sawadogo, Semafo Burkina Faso's Mine Chief Geologist and reviewed 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 compliancy with the Canadian National Instrument Standard 43-101.
    All individual drilling samples represent one-meter of drilling which
were split in half for cores and RC drill cuttings riffled spit to end to 1kg
samples. One half core or a 1kg RC sample was kept on site as a control and an
equivalent sized sample was then sent for preparation and gold assaying at the
Abilab laboratories in Ouagadougou, Burkina Faso. Each sample was fire assayed
for gold content on a 50-gram pulp sub-sample at the same Abilab laboratories.
Complementing Abilab's own QA/QC (Quality Assurance / Quality Control)
program, a QA/QC program was in place throughout the sampling program, using
blind duplicates and recognized industry standards.
