Cyprium Metals reports Nifty Copper leaching milestones

Cyprium Metals executive chairman Matt Fifield talked with Proactive about key commissioning milestones at the Nifty Copper Complex in Western Australia, as the company advances heap leach operations and prepares for first copper cathode production.
Fifield explained that commissioning activities are progressing across the heap leach operation, while pre-commissioning work on the solvent extraction and electrowinning (SXEW) plant is approaching completion.
The company has achieved targeted injection flow rates through its direct injection leaching process, building on more than a year of trials and testing to establish the technology's suitability for the existing Nifty heaps.
Fifield said early commissioning results had been particularly encouraging, with copper recovery responding quickly to acid injection and copper-to-acid ratios performing better than initially anticipated.
The interview also covered grade control drilling, which has reconciled within approximately 5% of the existing mineral resource block model, strengthening confidence in the company's production assumptions.
Cyprium Metals has established 212 production and monitoring wells, providing access to approximately 1.7 million tonnes of material and supporting an estimated six to eight months of planned production under conservative recovery assumptions.
Fifield also outlined the remaining milestones ahead of wet commissioning, including the installation of programmable logic controller (PLC) controls and energisation of the SXEW plant, following the introduction of high-voltage power to the plant infrastructure.
With heap leach operations ramping up and commissioning milestones being achieved, Cyprium Metals is progressing towards its next stage of copper production at Nifty.
