Au Equivalent Gold Equivalent calculation is based on Gold and Copper prices as at 30 June 2026 of USD $4,060/ oz of Gold and USD $ 13,400/ tonne of Copper. Metallurgical recoveries are assumed to be equivalent to published recent Cadia Valley recoveries of 80% for gold and 85% for Copper. Au Eq ounces of gold is calculated as ounces of gold plus tonnes of copper * ((13400*0.85)/(4060*0.80)) ounces of gold
