Koryx Copper Inc. has announced the filing of its Preliminary Economic Assessment (PEA) for the 100%-owned Haib Copper Project in southern Namibia. The technical report was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects.
The assessment builds on results first announced in September 2025, confirming the project’s strong economic potential. The latest update also incorporates molybdenum, following metallurgical test work that supported recovery assumptions.
According to the company, the PEA outlines plans for an open-pit mining operation, with flotation applied to sulphide mineralisation exceeding 0.225% copper, and heap leaching combined with copper solvent extraction and electrowinning (SX-EW) for oxide and transitional mineralisation above 0.15% copper, as well as low-grade sulphide material ranging from 0.15% to 0.225% copper.
“Koryx Copper Inc. is pleased to announce filing of the recently completed Preliminary Economic Assessment (‘PEA’) of the Company’s 100%-owned, flagship Haib Copper Project in southern Namibia. The results of the PEA were announced in the Company’s news release on September 4, 2025,” the company said.
The Haib Project is reported to host a substantial mineral resource, estimated at 511 million tonnes grading 0.33% copper and 51 parts per million (ppm) molybdenum in the Indicated category, and a further 308.9 million tonnes grading 0.31% copper and 40 ppm molybdenum in the Inferred category, using a 0.15% copper cut-off.
This equates to approximately 2.6 million tonnes of contained copper and 38,000 tonnes of molybdenum.
Koryx noted that Haib is one of the oldest known porphyry copper deposits globally, and one of only two of its kind in southern Africa.
The deposit has seen extensive exploration, with over 80,000 metres of drilling conducted since the 1970s by major operators including Falconbridge, Rio Tinto, and Teck.
The PEA was reviewed and approved by Qualified Persons, Jeremy Witley of The MSA Group and Werner Moeller of Qubeka Mining Consultants, both independent experts in geology and mining engineering.
