PERTH (miningweekly.com) – Base-metals-miner Kagara expects to produce around 23 000 t of copper and 50 000 t of lead plus zinc metal for the 2010/11 financial year.
The forecast has remained unchanged, despite the severe weather affecting the state of Queensland.
Kagara said in a statement on Wednesday that its operations remained largely unaffected by the recent floods in southern Queensland. The only site to be seriously affected was the Thalanga operations, which was in the process of commissioning the Thalanga polymetallic processing facility, and developing the Vomacka openpit operation.
Rainfall for the month of December had reached 388 mm at Thalanga, the highest in recorded history, with the total quarterly rainfall of 719 mm also a record, and 40% higher than the previous highest rainfall over the same period.
“These unseasonal events have resulted in a delay to full-scale production from Thalanga, and although the short-term cash flows are impacted [on] by this delay in commissioning, we expect to recover metal production in the second half of the financial year by increased throughput and as the openpit progress into the primary zone,” the company said.
Kagara’s Thalanga polymetallic plant was formerly a copper plant, which has been reconfigured to a polymetallic plant to allow the processing of ore from the Vomacka polymetallic deposit, which is located adjacent to the processing plant.
The refurbishment enables the plant to process both polymetallic and oxide ore types, as well as primary copper ore. On completion of mining at Vomacka, it is expected that the Thalanga treatment plant will then process ore from the West 45, Orient, Waterloo and Liontown polymetallic deposits, which contain a combined total of 3,1-million tons grading 8,8% zinc, 2,5% lead, 0,9% copper, 40 g/t silver and 0,6 g/t gold.
