Action Plan Implemented at Kiniero Mine

Montreal, Quebec, September 11, 2007 - SEMAFO (TSX-SMF) today announced a series of initiatives and detailed action plan to address the disappointing results experienced at its Kiniero mine. 

Since the inception of mining activities in 2002, the Kiniero mine has produced 238,000 ounces of gold primarily from mining narrow vein-type structures.  During this period, the company has been adept at exploiting these structures using its acquired knowledge of the area's geology to produce gold in an economic fashion.  Recently, however, the structures within the actual pits were recognized as subsidiary structures of those from the old pits. These substructures, planned as the principal source of ore for 2007, differ from those previously mined, generating additional internal dilution and added complexity in mining.  Previously published results show an increase in stripping ratios from what historically ran in the range of 10:1, to 17:1 this year.

Following a full geological review initiated and directed by our qualified person, Michel Crevier, implementation of a series of initiatives is underway that will restore the mine to satisfactory economic production during the 4th quarter of 2007. Principal aspects of these initiatives include:   

• Initiation of a geological review and comprehensive analysis in order to further validate our understanding of those areas to be mined in 2008.
  
  
• A shift of mining operations from the current Northeast Gobele D and Gobele C pits to the West Balan pit. West Balan area holds more than 77 000 oz. of gold, which we expect to mine at an average strip ratio of 7:1.  Cash operating costs in West Balan are estimated at $350-$375 per ounce.  Recent drillings confirm the presence of larger structures in the West Balan deposit, which is host to a more continuous and homogeneous mineralization.  Previously announced exploration results also demonstrated further potential of extended mineralization to the west.
  
  
• Mill maintenance work originally scheduled for this December is taking place at present in order to ensure high availability and satisfactory throughput throughout the 4th quarter.
  
  
• An access road has been established to the West Balan pit, located 5km from the mill.
  
  
• Pre stripping mining activities have been initiated and transport of the first ore to take place early in Q4.

Semafo's Mining Operations Manager since 2004, Patrick Moryoussef, Mining Engineer, has relocate as an expatriate to assume the mine manager function temporarily during the implementation of these important initiatives.

"Kiniero production is unsatisfactory," said Benoit Desormeaux, Semafo's Chief Operating Officer who is currently directing operations from the site. "We remain confident, however, that actions currently underway will return Kiniero to proper production levels as of Q4 2007 and set the stage for 2008."

As a result, the 2007 Kiniero production forecast has been revised to 30,000 ounces. The above initiatives will see a return to production levels in 2008 in the 45,000 oz. range which is consistent with the average historical production level for the mine.
