THE average all-in sustaining cost for gold mines in Australia and New Zealand rose in the September quarter, according to Aurum Analytics and PCF Capital Group.
AISC for the quarter averaged A$1422 an ounce, up 3.2% or $45/oz quarter-on-quarter.
The average spot gold price for the quarter rose from $2604/oz to $2669/oz.
The lowest cost producer for the quarter was Evolution Mining's 30%-owned Ernest Henry operation in Queensland, which reported AISC of -$515/oz due to copper by-product credits.
Newcrest Mining's Cadia mine in New South Wales, which also produces copper, reported AISC of $158/oz.
On a co-product basis, Aurum estimates Ernest Henry's AISC as $875/oz and Cadia's as $921/oz.
Kirkland Lake Gold's Fosterville mine in Victoria was third with AISC of $488/oz, but was the lowest cost gold-only producer.
Saracen Mineral Holdings' Thunderbox open pit and underground operation was fifth and the lowest cost producer in Western Australia with AISC of $790/oz, while Evolution's Cowal mine in NSW had the lowest costs for an open pit-only operation at $1026/oz.
There were eight gold mines that reported AISC of over $2000/oz, six of which were in WA.
