Waihi again figures in Australasian gold report
By Ross Louthean

The March quarter gold report of Aurum Analytics shows that the Waihi gold operations of OceanaGold Corporation figures strongly in both production and operating cost terms against the vast gold output by Australian mines.

The report deals with gold production in both Australia and New Zealand, with Aurum Analytical linked to Australian broking house PCF Capital.

Waihi was ranked 17th in production, the Super Pit in Kalgoorlie operated by Newmont Mining and Barrick Gold dominating with output for the three months of 172,000 ounces from both open pit and underground.

Next was the Boddington open cut in Western Australia for Newmont Mining with 163,000 oz and then Newcrest Mining’s underground operations at Cadia in New South Wales, where some operations are still impacted by a seismic event several months ago. Cadia produced 142,970 oz for the quarter.

Aurum Analytics said that of the companies that report all-in sustaining costs AISC Wahi was placed 17th in the March quarter with AISC costs of $A1,048/oz.

Once again the leading producer in this category was Evolution Mining’s Ernest Henry mine in Queensland with an AISC of minus$A510/oz despite an average grade of 0.56 grams/tonne. The low cost was due to the high copper content at Ernest Henry.

Aurum Analytical said the average AISC for the Australasian miners was $A1,111/oz. Grade-wise for the companies reporting AISC figures, the reported mill head/feed grade was 3.61 grams/tonne which was down on the figures for the December quarter.
