Dear Laverton

I think it would be a bit unfair to suggest that the cost structure of all ounces produced in 2023 will be the same as the transitional Dec 2022 Quarter.

We do have those material strip ratio changes coming at Missouri, we will be producing more ozs on an annual basis if 1.2 mtpa throughput maintained/exceeded, and the head grades should progressively improve as the year pans out with better open cut mine management, less dilution and the selective underground ambitions under Riverina.

Overlay that then with the exciting exploration upside evident in that area around old open pits.

I recall guidance was back around $2250 an ozs for the financial year, but that may change.

$A gold also looking good.
