PERTH, Western Australia, Nov. 11, 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 has been performing to expectation during the
commissioning stage with some further improvement in recoveries. Key
commissioning statistics for October 2011 were:
296,670 dry tonnes, September 331,700;
570 hours, September 570 hours;
25.9%, September 27.5%;
Post gravity float recovery
79.5% with a mass pull of 0.81%, September 77.2% with a mass pull of
Overall calculated recovery
79.5%, September 77.5%; and
8,230 ounces, September 8,960 ounces.
Throughput rates and operating hours were below target due mainly to 139
hours of crusher down-time caused by oversize rock feed and tipping
practices and 81 hours lost due to tails storage and process water
pumping limitations. The crusher issues have been addressed by
modifying ore dumping procedures, adjusting blast patterns to provide
increased rock fragmentation for optimal crusher throughput and
modifications to the ROM bin, which are 50% complete.
Plant throughput rates were also restricted due to the filling of Stage
1A of the tailings dam and redeployment of pumping and piping
facilities to the larger Stage 1B section of the dam, together with
some process water shortages caused by lightning strikes affecting
pumping capacity. Stage 2 of the tailings dam is well ahead of
Recoveries continue to improve and are good considering the blend of
lower recovery oxide and transition ore with the high recovery fresh
ore and the interruptions to steady processing rates.
Grade control drilled ore to date exceeds the reserve model estimate in
terms of tonnes (+17%) and contained gold (+13%). Most of the excess
contained ounces have come from AF-Gap, where mining is still in the
oxide zone. Mill calculated head grades for the 721,000t treated to the
end of October are higher than feed grade estimated by grade control
Despite unseasonably high rainfall of 315mm making October the wettest
month this year, the mining contractor mined a total of 851,000Bcm
compared to 924,000Bcm in September 2011. Stockpiled ore tonnages have
increased to about 1,200,000 tonnes grading 1.10g/t gold, comprising
380,000t of sulphide ore and 820,000t of oxide ore.
Mark Calderwood, Managing Director's Comments
"Recoveries are good, the reserve reconciliation is positive and, as we
iron out 'teething' issues with the plant, we expect to increase mill
operating hours and throughput rates."
"Consumable levels remain low, with 0.06kg/t of cyanide and 0.78kg/t of
steel balls consumed per tonne of ore feed."
In addition to the previously announced appointments of a Chief
Operating Officer and Deputy General Manager during the September
quarter, Wayne Nicoletto commenced as General Manager for Edikan last
week. Wayne is a senior mining professional with 30 years industry
experience in Africa (7 years), Australia, Canada and Central Asia.
