Perseus Mining Limited - Commissioning Update, Edikan Gold Mine, Ghana


PERTH, Western Australia, Sept. 15, 2011 /CNW/ - Perseus Mining Limited (ASX/TSX: PRU) is pleased to provide an update on commissioning at its Edikan Gold Mine ("EGM") in Ghana.

The process plant is currently achieving increasing rates of utilisation (87%) and mill throughput rates have recently been tested to 730t/hr (5.9Mt/annum) for short periods on fresh/transition ore blends.   Significantly, at 730t/hr the net power draw for the SAG mill is 10MW of the 14MW capacity with the SAG Mill variable speed drive control operating at low speed.  A recent inspection inside the SAG mill has revealed minimal wear.

The primary crusher has reached 1,300t/hr (10Mt/annum) throughput rates.

Gravity, float and CIL gold recoveries from both low grade and higher grade feed are in line with expectations.  Combined recovery is currently about 74%, which is consistent with expectations for the current stage of commissioning and the blend of fresh and oxide material. Gravity gold recovery is on target at 30%.

To date calculated head grades appear on average to be marginally higher than grade control estimated head grades, and grade control tonnes and grade estimates to date are, on average, each slightly higher than exploration model grades for the corresponding areas.

The Company has also received approval to deposit float tailings into stage one of the floatation tailings storage facility.

Mining is ramping up with the first of two Liebherr R9250E Excavators now commissioned and operating.

The first gold shipment from the Edikan Gold Mine, just over 65kgs or approximately 2,100 fine troy ounces of gold was sent to Rand Refineries Limited in South Africa for processing on 13th September.

Mark Calderwood, Managing Director's Comments

"We have achieved two further milestones by processing ore through the mill at 730tph and making our first shipment of gold in recent days.  The process plant is running smoothly, with the mill only drawing about 80% of its power rating during this early commissioning phase."
