Pre Glencore:
Pursuant to the RNS on 1 August 2024, Enprotec, the supplier of the flotation plant, has informed the Company that, in their opinion, no additional fundamental changes to the currently installed plant equipment are necessary to achieve the intended recoveries and grade. Enprotec has been conducting a series of laboratory tests to better understand the core processes of the plant, including reagent dosing amounts and points, agitation speeds, flow rates between components, slurry densities, cell residence times, and alternative water sources introduced into the flotation section. These tests are crucial for further optimising the flotation circuit.
Enprotec has notified Premier that they anticipate completing all laboratory test work by the end of this week, at which point the lead time for restarting operations will be determined.
At the same time, the Company has also been conducting a further financial review of the potential operating costs at Zulu with consideration of the impact of an enlarged float plant in due course to accommodate the surplus capacity on the front end of the plant. Internal Company estimates, which have not been independently verified, indicate that an enlarged float plant could result in a target mine gate production cost for spodumene concentrate of circa US$500 per ton.
