"Given cost inflation and this delay, a project review is underway with results to be published once the review and
final engineering completes on all aspects. That exercise is wrapping up now with outstanding matters
such as final engineering on the tailings disposal pipe to complete shortly. To mitigate cost inflation, cost
savings are being worked through also, for example targeting lower capex for the wharf. Ordering of
essential items / on major contracts is to resume in 1H22 once budgets are finalised."
