Koryx Copper Inc. (TSX-V: KRY) is pleased to announce that it has closed (i) its previously announced bought deal public offering of an aggregate 19,047,680 common shares of the Company at a price of C$1.05 per Common Share for aggregate gross proceeds to the Company of C$20,000,064, inclusive of the exercise in full of the over-allotment option granted to the Underwriters (defined herein), and (ii) closed a concurrent non-brokered private placement of an aggregate 4,761,844 Common Shares also at the Issue Price for total gross proceeds of approximately C$5,000,000.

The Offering was led by Stifel Canada, as lead underwriter and sole bookrunner on behalf of a syndicate of underwriters that includes Beacon Securities Limited, Haywood Securities Inc., Research Capital Corporation, BMO Capital Markets, Red Cloud Securities Inc. and Ventum Financial Corp.

Heye Daun, Koryx Copper’s President and CEO commented: “We are delighted  with the continued  support received from our longstanding shareholders, especially Ross Beaty,  and a number of European and North American financial institutions who have invested with us repeatedly over the years. In addition, the Koryx executive team followed my significant investment, into this financing. 

We are also very grateful for the very strong interest shown by Namibian institutional and private investors who made up more than 40% of this financing. This is a very strong vote of confidence from Namibian investors who are playing an increasingly important part in the evolving shareholder base of Koryx Copper and who have endorsed our strategy for the fast-tracked development of the world-class, long-life and low-cost Haib copper deposit in the south of Namibia.

With this capital in hand, we are well positioned to accelerate technical work, optimize our development plans, and unlock significant value. We are excited for the months ahead as we move rapidly toward key milestones, including the optimization and right-sizing of Haib as we advance toward our PEA and PFS. The momentum is building, and I look forward to sharing our continued progress.”

The Common Shares issued under the Offering were offered by way of a short form prospectus dated July 29, 2025 filed in each of the provinces and territories of Canada, except Québec, and offered in the United States on a private placement basis pursuant to an exemption from the registration requirements of the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), and in those jurisdictions outside of Canada and the United States as agreed to by the Company and the Underwriters, in each case in accordance with all applicable laws and provided that no prospectus, registration or other similar document is required to be filed in those jurisdictions.

The Company intends to use the net proceeds of both the Offering and Placement to advance technical studies on the Haib Copper Project and continue exploration on the property, working capital and general corporate purposes.

All Common Shares issued under the Placement are subject to a hold period expiring four months and a day from the date of issuance. The Company paid finder’s fees of C$374,455 to Cirrus Capital (Pty) Ltd. in connection with the Placement.

About Koryx Copper Inc.

Koryx Copper Inc. is a Canadian copper development Company focused on advancing the 100% owned Haib Copper Project in Namibia. Haib is a large, advanced (PEA-stage) copper/molybdenum porphyry deposit in southern Namibia with a long history of exploration and project development by multiple operators. More than 80,000m of drilling has been conducted at Haib since the 1970s 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. Haib has a current mineral resource of 414Mt @ 0.35% Cu for 1,459Mt of contained copper in the Indicated category and 345Mt @ 0.33% Cu for 1136Mt of contained copper in the Inferred category (0.25% Cu cut-off).

Mineralization at Haib is typical of a porphyry copper deposit and it 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 mineralization and alteration features typical of these deposits. The mineralization 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, “NI 43-101 Technical Report – August 2024 Mineral Resource Estimate for the Haib Copper Project, Namibia” dated effective August 31, 2024. The Technical Report and other information is available on the Company’s website at https://koryxcopper.com and under the Company’s profile on SEDAR+ at www.sedarplus.ca.
