*Based on 0.3% Cu equivalent cut-off grade. The equivalence formula (EQCu = %Cu + g/t Au x 0.564 + Fe x 0.01) was calculated using metal pricing of $1.70 per pound copper, $59 per tonne iron concentrate and $730 per troy ounce gold with estimated recoveries of 80% Cu, 70% Au and 42% Fe.
Approximately 90% of the resource in the Serrote Deposit lies within the sulphide zone, with the remainder lying within the overlying oxide/transition zone.
