Manuka Resources Restarts Gold Production at Wonawinta Processing Plant

Gold Production Resumes at Wonawinta

Manuka Resources Limited (ASX:MKR) has officially restarted gold production at its Wonawinta processing facility, marking a key operational milestone after an extensive five-month recommissioning phase. The company is now processing stockpiled ore from its wholly owned Mt Boppy gold mine, with more than 50,000 tonnes of material grading approximately 1.1 grams per tonne of gold ready to feed the plant. Manuka aims to process between 125,000 and 140,000 tonnes of this ore over the next three months, signalling a focused push to establish consistent gold output.

Upgrades Pave Way for Silver Production

The recommissioning program at Wonawinta included significant upgrades to power generation, laboratory facilities, and key processing components. These improvements lay the groundwork for the next phase: silver production, which is targeted to begin in the fourth quarter of 2026. Central to this is the installation and commissioning of a new de-slime circuit designed to enhance processing of the clay-rich silver ores. Once operational, the plant will be capable of simultaneously processing both gold and silver ores, diversifying Manuka’s precious metals output.

Strategic Importance of Cobar Basin Assets

This restart is not just a short-term production boost but the start of Manuka’s sustained precious metals strategy across its Cobar Basin portfolio. Executive Chairman Dennis Karp emphasised the significance of this milestone, highlighting the immediate focus on ramping up gold processing while continuing upgrades for silver. The company’s broader vision is to leverage its upgraded facilities to maintain steady output and capitalise on both gold and silver markets.

Next Steps and Market Implications

Manuka’s progress follows a series of preparatory moves, including a 28% boost to its Wonawinta ore reserve earlier this year and securing funding to support plant upgrades. The transition to silver production will be a critical catalyst to watch, as it will unlock additional revenue streams and operational flexibility. However, the timing depends on the successful completion of the de-slime circuit and associated plant enhancements, which remain subject to commissioning risks.
