About Koryx Copper S.A.
Koryx Copper S.A. is a Luxembourg domiciled copper development Company focused on advancing its 100% owned Haib Copper Project in Namibia whilst also building a portfolio of copper exploration licenses in Zambia. Haib is a large, advanced (PEA-stage) copper/molybdenum/gold porphyry deposit in southern Namibia with a long history of exploration and project development by multiple operators.
More than 120,000m of drilling has been conducted at Haib since the 1970's with significant exploration programs led by companies including Falconbridge (1964), Rio Tinto (1975) and Teck (2014). Extensive metallurgical testing and various technical studies have also been completed at Haib to date. Additional studies are underway aiming to demonstrate Haib as a future long-life, low-cost, low-risk open pit, sulphide flotation copper project with the potential for additional copper production from heap leaching.
Mineralisation at Haib is typical of a porphyry copper deposit and is dominantly chalcopyrite with minor bornite and chalcocite present and only minor secondary copper minerals at surface due to the arid environment. Haib is one of only a few examples of a Paleoproterozoic porphyry copper deposit in the world and one of only two in southern Africa (both in Namibia). Due to its age, the deposit has been subjected to multiple metamorphic and deformation events but still retains many of the classic mineralisation and alteration features typical of these deposits. The mineralisation is dominantly chalcopyrite with minor bornite and chalcocite present and only minor secondary copper minerals at surface due to the arid environment.
Further details of the Haib Copper Project are available in the corresponding technical report titled, "Preliminary Economic Assessment of the Haib Copper Project, Namibia, National Instrument 43-101 Technical Report" dated effective October 8, 2025. The report and other information is available on the Company's website at www.koryxcopper.com and under the Company's profile on SEDAR+ at www.sedarplus.ca.
