Ann: AUZ secures funds to accelerate cobalt and nickel projects, page-308

You are making absolutely no sense. Breaking down into stages can mean many things but if you mean infrastructure first, process plant second, mining development third this in no way cuts Opex for a operating producing plant. It is a mining operation meaning you mine and then in the operation here process it into sulphates for sale.
As For Lower Capex the only way Capex can be reduced is if Gov contributes to infrastructure, apart from that it is and will always be mine, crush, thicken, leach thru HPAL, separate solution by CCD's, POX, Precipitate, separate via SX, crystallise.
Please explain how Capex reduces for this process, it is the only way of doing it?
