SEMAFO Initiates Feasibility Study of Wona Mineralization at Depth


MONTREAL, Jan. 21 /CNW Telbec/ - SEMAFO (TSX: SMF) today announced the selection of engineering and specialized firms to conduct the Pre-feasibility and Feasibility Studies ("PFS/FS") of the Wona mineralization at depth, at the Company's Mana mine in Burkina Faso. The objective of the PFS/FS is to confirm the economic viability of an underground mining operation using an updated resource model. Results of the pre-feasibility and feasibility studies are expected in Q2 and Q3 2010, respectively.

The PFS/FS come on the heels of a positive Preliminary Economic Assessment ("PEA") completed by the engineering group Met-Chem Canada Inc. ("Met-Chem") in Q4 2009, which confirmed the potential of the Wona underground deposit.

The PEA was based on the December 2008 resources estimates with the inclusion of 2009 drill results up to hole WDC99, which represented indicated resources attributable to the underground mine of approximately 4.5 million tonnes at 3.2 g/t Au diluted for over 460,000 ounces. The PFS/FS will be based on an updated model, which will include all 2009 drilling results (up to hole WCD177). The updated model will incorporate 78 additional drill hole results not included in the previous resources model of the deposits, including among others:

Met-Chem will continue as the Company's engineering consultant for the project and will be responsible for overseeing the PFS/FS, in conjunction with Golder Associates Ltd. and SGS South Africa (Pty.) Ltd. and in accordance with standards set out in National Instrument 43-101.

"The contracts awarded for these studies represent an investment of approximately one million dollars," said Benoit Desormeaux, SEMAFO's Executive Vice-President and COO. "The teams are currently on site collecting the data necessary to complete the studies and are working in close collaboration with SEMAFO's experienced underground mining team led by Patrick Moryoussef, Mining Operations Manager, Michel Crevier, Geology Manager and Qualified Person, and Michel Labonté, Mana Mine Manager."

"We are eager to complete the studies," said SEMAFO'S President and CEO, Benoit La Salle, "We are confident that the ongoing drilling program will have a positive impact on the resources that will be used for the feasibility study. We also believe that considering the excellent drilling results and increasing gold prices, the underground resources will take on a whole new dimension moving forward."

"We consider the study to be an integral part of our organic growth strategy and key to unlocking further value for the Company and its shareholders. We were very pleased with the PEA results and look forward to realizing Mana's true potential," added Mr. La Salle.

The internal rate of return on this Wona mineralization at depth is excellent with the remaining results from the 2009 drilling program yet to be included.

Drilling programs remain ongoing at Mana to extend the at-depth mineralization, as the structure remains open in all directions. As part of the current exploration programs, drilling to further validate the on-surface potential of the property is also in progress. The 2009 drilling results will be taken into account in the calculation of SEMAFO's updated reserves and resources as at December 31, 2009.
