MINERAL PROCESSING FROM OPEN PIT AND UNDERGROUND
Gold production for the quarter ended 30 June 2012 of 5,917 ounces was in line with management expectations, held back slightly by the constraint in tailings disposal from the process plant during Tailings Dam 3 (“ TD3”) remedial works.
Mining activities were primarily from the main open pit, with small quantities coming from the north pit. There were modest amounts of ore extracted from the underground mine. These underground ores are for the time being stockpiled until the planned improvements to the mineral process plant are completed in early Q4 2012, this will allow the high grade ores to be processed once the plant recovery levels are consistently above 81% and not at the current 78-79% recovery levels.
The process plant recovery continues to be below budgeted levels. The cause of this relates to an increased level of ore hardness and increased abrasiveness. Remedial works to modify the plant are on-going and are expected to be complete in early Q4, 2012; so that higher recovery levels can be attained and the stockpiled higher grade underground ores can be processed more efficiently.
UNDERGROUND
The mining of ores from the underground was temporarily suspended in early June and re-scheduled until mid-July to take into account significant water in-flows that diverted equipment from ore mining to a focus and accelerate infrastructure development. This allowed continued development of the underground decline which acted as an additional temporary sump and the construction of an additional water chamber. The main water pump station at the base of the shaft w
