The new 4.7 million tonne per annum processing plant at KOTH is now processing ore, initially a mix of low-grade development ore from stage one of the open pit and existing stockpiles, while final commissioning of the processing circuit is completed.
First gold is expected in the near future, before the company's end of the quarter deadline.
Red 5 managing director Mark Williams said KOTH remained on time and on budget, with underground and open pit mining now in full swing, and the third open pit fleet now ramping up.

KOTH will become a central processing hub for Red 5's Darlot underground and satellite open pits in the Leonora district, such as Great Western.
Red 5 expects KOTH will become a long-lived, top 10 Australian gold mine.
