Work is well under way on refurbishment of the Thalanga processing plant south-west of Charters Towers as zinc developer Red River Resources pursues its $17.2 million plan to restart operations.
Work completed to date includes removal and refurbishment of concentrate thickener rakes, removal and refurbishment of Mill 3 feed chute, rebuild of a ball mill hopper, cleaning out concentrate storage bunkers, and comprehensive NDT (non-destructive testing) work.
“This work forms an important step towards the full restart of the Thalanga zinc project and will enable us to further tighten the budget and timeline for the remaining restart work at the Thalanga processing plant,” Red River managing director Mel Palancian said..
“We intend to keep the market informed as we progress with the Thalanga processing plant refurbishment. We are excited to undertake this work, which will further improve our capacity to quickly and efficiently deliver the restart of the project.
As part of the refurbishment and rehabilitation activities, the concentrate storage bunkers are being cleaned out for inspection and corroded steel will be replaced where required.
Red River says the base metal concentrate will be stored on site and will be sold when production recommences.
Work has also commenced on the refurbishment of the grinding circuit.
Mill 3 feed chute has been removed and dispatched to Townsville to be rebuilt. The ball mill hopper for Mills 1 & 2 has been rebuilt on site and is awaiting installation.
Red River Resources anticipates an annual average production of 21,400 tonnes of zinc, 3600 tonnes of copper, 5000 tonnes of lead, 2000 ounces of gold and 370,000 ounces of silver in concentrate when production resumes.
The initial mine life estimate is five years, but there is extension potential.
The Thalanga zinc project restart study was based on production from three deposits – West 45, Far West and Waterloo.
