Access development from Savannah to first ore at Savannah North is approximately nine months, and full production from Savannah North is reached 15 months after commencement of development (unchanged from the Feasibility Study).
The optimised mine plan has a mining production target of 7.59Mt @ 1.42% Ni, 0.68% Cu and 0.10% Co, containing 108,100t Ni, 51,300t Cu and 7,200t Co. Total ore tonnes mined and development rates are shown in Figure 1.
The optimised mining plan includes approximately 1.1% of contained nickel derived from material classified as Inferred Resource (Table 3). The maximum annual contribution of contained nickel derived from Inferred Resources is 2.4%, four years after commencement of mining (Figure 2).

There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised.
