According to Shire records: check it out : http://www.cobar.nsw.gov.au/our-town-and-shire/mines
"The CSA mine is an underground mine, mining copper ore at a rate of 1,200,000 tonnes per annum. The ore is predominantly chalcopyrite (a copper iron sulphide), which produces a concentrate containing approximately 29% copper metal
In 2009, the CSA Mine recorded its highest output ever, with over 182,000 tonnes of concentrate being produced, containing in excess of 51,000 tonnes of copper metal, and 400,000 ounces of silver."

According to Glencore, finished copper production from own sources was 72,200 tonnes, so assuming Cu production remained flat since 2009, Cobar is responsible for 51,000t Cu out of a total of 72,000t Cu. However, in 2012 Glencore is reporting:
Copper production from own sources was 8% lower than the comparable period, however copper cathode production increased from 9,000 tonnes to 37,000 tonnes as Kazzinc’s new copper smelter (commissioned in H2 2011) continued its ramp-up.
