MINING AND PROCESSING OPERATIONS
During the quarter ended 30 September 2012, open pit mining operations extracted 185,300 tonnes of ore averaging 1.2g/t Au.
The metallurgical plant processed 167,242 tonnes of open pit and underground material and produced a total of 5,875 ounces of gold and 7,469 ounces of silver; with plant recovery averaging 80.8%. Plant throughput was constrained by reduced tailings dam capacity which will improve in Q4 with the reinstatement of Tailings Dam No. 3.
UNDERGROUND
Trial mining from the underground delivered 15,125 tonnes of ore averaging 3.32g/t Au. Some of this ore has already been processed and the remainder will be processed in Q4.
During the past quarter a strategic review of the underground operations was completed which led to a decision to temporarily suspend underground operations. The contractor is currently completing mining of accessible ore zones and will demobilise from site in late October 2012 at which point capital expenditure on the underground mine will temporarily cease.
UNDERGROUND DRILLING
As part of the strategic review of the underground operation, Hambledon’s 25,000m diamond drill programme will continue. To date, some 17,500 metres has been drilled. The next set of drill results will be announced shortly.
INFRASTRUCTURE
The repair to Tailings Dam No. 3 is complete. The dam is expected to be commissioned in November 2012 after receipt of government permits.
