SEMAFO Reports Discovery of Two New Gold Zones at Samira Hill


Libdorado North Zone Returns Up to 5.59 g/t Au over 10 m and 5.11 g/t Au over 11 m

MONTREAL, March 8 /CNW Telbec/ - SEMAFO (TSX: SMF) today announced the discovery of 2 new gold zones, the Lidorado North Zone and the Boulon Jounga Extension at its Samira Hill Mine in Niger.

    Libdorado North Zone

The Libdorado North Zone is located immediately north of the Libiri open pit. Within the Libdorado North Zone, three zones of gold mineralization were crossed over a strike length of 350 meters returning the following significant gold values. (General direction is WNW dipping NE.)

Auger, reverse circulation ("RC") and core drilling programs were initiated following compilations of IP and magnetic geophysics, geochemistry, drilling and mapping, in conjunction with a recent special structural model proposed by external geological consultant, Dr. Damien Gaboury. Although the main focus remains the Samira Horizon, Dr. Gaboury's map and conclusions reveals new potential from interpreted structural thickening by stacking of favourable aggregation of stratigraphic complex in specific structural conditions (Figure 1). Libiri geological environment of the results with mineralization-interpreted trends are shown on Figure 2.

The RC drilling program was initiated late 2009. At the end of January 2010, 22 holes were completed, representing a total of 2,330 meters of drilling.

Boulon Jounga Extension


The approval of the Boulon Jounga mining permit in August 2009 and the confirmation of the deposit's high grade ore, exposed an unexplored area that could quickly produce quality mill feed material for Samira Hill. To date, 126 holes representing a total of 12,186 meters have been drilled in the Boulon Jounga area.

The Boulon Jounga potential area trends northeast over more than 8 kilometers with mineralized structures shallowly dipping to the northwest. An auger drilling program was initiated in 2009. At the end of January 2010, 2,891 holes were completed, representing 35,602 meters of drilling. Some results from the program remain pending. Nonetheless, an RC drilling follow up program on the Boulon Jounga area is already considered a success with the discovery of two areas that may potentially become part of the reserves base. Holes 09BJRC58, 62, 104 and 103 all align along the north limb of volcanics overlaying the Boulon Jounga pit deposit. Holes 09BJRC108, 75 and 85 are located on the south side. The geological environment of these results and mineralization-interpreted trends are shown on Figure 3.

"The Samira Horizon remains an important mining district for SEMAFO, hence our decision earlier this year to proceed with a two-year $6,000,000 exploration program on the property," commented Benoit La Salle, President and Chief Executive Officer, "We are encouraged by these new discoveries at Samira Hill, the results of which may become part of our reserves and resources base and ultimately extend mine life. We believe that our continued exploration programs to fully define the property will ultimately benefit from existing infrastructures and contribute to increase value for our shareholders."

The exploration programs were designed and managed locally by Faustin Yameogo and Aziz Amane, Samira Hill's Exploration Chief Geologists and Richard Roy, Deputy Geology Manager, under the guidance, supervision and 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.
