Koryx Copper has provided an interim update on its Pre-Feasibility Study (PFS) for the wholly-owned Haib Copper Project in southern Namibia, confirming all workstreams remain on schedule for publication before the end of November 2026.
The company said that PFS metallurgical test work results are near complete and show consistency with historical results, supporting PFS metallurgical assumptions and by-product recovery potential.
Major flowsheet improvements have been achieved, including the elimination of the heap leach component, with all production now via milling and flotation, it said.
Significant low-grade material rejection through coarse particle flotation (CPF) and the application of Jameson cells have also been incorporated.
Koryx said a debottlenecking study improved the PFS base case crushing throughput to 48 Mtpa, with CPF rejecting approximately 12 Mtpa of coarse gangue at 0.05% Cu ahead of flotation, resulting in 36 Mtpa of main flotation circuit throughput at higher copper grades. CPF is an advanced mineral processing method that enables efficient recovery of coarse mineral particles up to 450μm in the Haib tests.
The company said extensive Jameson cell and CPF testwork were completed with excellent results.
Jameson cells in conjunction with conventional flotation will enable target copper recovery to be maintained while facilitating increased final concentrate copper grade and reduced power and space requirements for flotation.
“With conversion drilling now completed for the PFS and our metallurgical, infrastructure and permitting workstreams all advancing in parallel, we remain firmly on track to deliver the Haib PFS before the end of November 2026,” said Koryx Copper president and chief executive Heye Daun.
On infrastructure, a Memorandum of Agreement was signed with NamPower, with grid connection engineering underway and final system design expected in November.
Power will be supplied via a 68km 220kV grid connection from Harib substation, supplemented by solar PV and battery energy storage.
The current power demand estimate is 260 MVA maximum demand, with annual electricity consumption estimated at 1.45 TWh, it said.
A Memorandum of Understanding was also signed with NamWater, with an Infrastructure Development Agreement for a bulk water supply system being developed.
The Orange River supply scheme was selected as the preferred, lowest-cost bulk water supply solution, with a single abstraction point approximately 9 km south of the mine.
The Environmental and Social Impact Assessment and Environmental Management Plan supporting the Environmental Clearance Certificate application for the Mining License Area and Water Abstraction were submitted to the Ministry of Environment, Forestry and Tourism on 19 August 2026 and 4 September 2026 respectively, with a decision expected before the end of 2027.
