High grade zone deepening at Mana



    SEMAFO TSX-SMF

    MONTREAL, March 24 /CNW Telbec/ - SEMAFO (TSX - SMF) is pleased to
provide an update on its exploration program undertaken on the Wona North East
Extension at its Mana Mine in Burkina Faso.
    Semafo has determined that the Wona deposit, which is advantageously
situated adjacent to the Mana processing plant, extends in a north-east
direction as well as at depth. Follow-up drilling has been carried out
confirming the presence of a mineralization lode for a distance of 500m under
the NE part of the Wona open pit outline. The lode extends for another 800m in
the NE direction, past the pit outline. Vertically, the lode covers a height
of at least 400m. The mineralization, whose width is greater than at
sub-surface, presents a number of high gold grades.
    Further drilling will aim at a better definition of the mineralization
and will focus on investigating the potential of an underground operation to
be located between 16050E and 17400E. In addition, the potential for
establishing two small open pits at 17,500E and 18,000E exist. The area herein
described is shown on attached longitudinal section displaying contoured
grades-thickness product in progressive cold to hot colors.

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

    Semafo's properties in Burkina Faso are within the Houndé
volcano-sedimentary belt. As described in previous technical reports, more
than one mineralization type has been recognized in the area, such the Nyafé
deposit which is of vein type in sheared volcanics and the Wona deposit, which
lies in meta-sediments. The latter is related to silicification which is often
brecciated and generally at proximity to a graphitic horizon.
    The drilling programs were designed and managed locally by Dofinta Bondé,
Mana Mineral's Exploration 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 Instrument 43-101.
    All individual samples represented one-meter length of core drilling
which was sawn in half or one-meter length RC drilling riffle spit to end to 1
Kg sample. One half core or 1 Kg RC sample is kept on site as a control and
identical sample for assay then 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 insurance
program was in place throughout the sampling program, using blind duplicates
and recognized industry standards.
