2026 PEA and PFS Plans

The Company plans to prepare a new 2026 PEA and publish it by late Q2 2026. In addition, the Company expects to complete 50,000 metres of additional infill and growth drilling before the end of the Summer of 2026. The results will be incorporated into another MRE update which will serve as the basis for the prefeasibility study (“PFS”) that is currently planned to be announced during Q4 2026.
RSU Issuance
The Company has approved the grant of up to an aggregate of 2,410,000 restricted share units (each, an “RSU”) to certain key executives, officers, consultants and directors of the Company pursuant to the Company’s Omnibus Plan, of which 1/2 of the RSUs will vest 12 months from the date of issuance, and then one-quarter each after 18 and 24 months. Each RSU represents the right to receive, once vested, one common share in the capital of the Company for every RSU held in accordance with the terms of the Omnibus Plan.
COO Succession
The Company also announces that Trevor Faber has accepted a senior project role with another mining company that is commencing project execution in the near term. The Board acknowledges that this new role aligns more closely with his background and the immediate execution demands of that project.

The Board thanks Trevor for his contributions and wishes him continued success in future endeavours.

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, 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 Technincal Report. 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.
