As a result, plant capacity is expected to attain up to 7,200 tonnes per day ("tpd") in bedrock and up to 8,000 tpd in blended ore. Completion of phase four will increase throughput by 1,200 tpd, representing an additional 26,000 to 30,000 ounces of gold annually when compared to current plant capacity. The primary changes to the processing plant include: Addition of a pebble crusher Utilization of the third ball mill, previously used as back-up Addition of two CIL tanks Addition of a thickener Additional gensets Critical spares Some equipment capacity upgrades The budget for this fourth phase of plant expansion is $25 million, including $18 million for enhancements to the plant and $7 million for additional mining equipment. "This fourth phase of plant expansion is scheduled for commissioning by year-end and has an estimated payback period of less than 16 months," said Benoit Desormeaux, SEMAFO's Executive Vice-President and Chief Operating Officer. "We expect to carry out the plant modifications with little or no disruption to our day-to-day operations as was the case with our recently-completed plant expansion project, which we accomplished on time and on budget."SEMAFO launched this new phase of plant expansion in consideration of the potential underground operation, continued growth in reserves and resources in the vicinity of the plant, as well as the excellent exploration results suggestive of the surrounding area's superior potential.In 2010 the Mana Mine produced 179,700 ounces of gold. Production guidance for 2011 has been established at between 170,000 and 190,000 ounces of gold. Mana's 2010 production number is preliminary and subject to final adjustment.
