KORYX COPPER FILES AN AMENDED PEA FOR ITS HAIB COPPER

PROJECT

Vancouver, B.C., Canada – January 22, 2024 – Koryx Copper Inc. (formerly Deep-South

Resources) ("Koryx" or “the Company") (TSX-V: KRY) announces that, further to its news

release dated February 7, 2023 confirming a continuous disclosure audit of the Company

by the British Columbia Securities Commission (the "BCSC"), it has filed an amended

preliminary economic assessment ("PEA") technical report (the "Amended Report") for the

Haib Copper project near Noordover in the south of Namibia. The amendment has not

impacted the material components of the PEA, notably resources, metallurgy, mine plan,

cost estimates, economic analysis and environmental matters (see the Company’s news

release dated December 15, 2020 announcing the results of its PEA).

As disclosed in its February 7, 2023 news release, because the Company was in a legal

dispute with the Ministry of Mines and Energy of Namibia (the “Ministry”) over the license

renewal of the project, the Company awaited to clarify the legal status of the license before

proceeding with the required amendments to the original technical report. Once the license

EPL 3140 Haib Copper was renewed in July 2023 by the Ministry, in order to address the

deficiencies noted by the BCSC and amend the report accordingly, the Company engaged

the services of Damian Connelly, B.Sc. App Sc, FAusIMM, FIEAust of METS Engineering

Group of Australia and Peter Walker, B.Sc. (Hons) Geology, MBA, Pr.Sci.Nat., of P & E

Walker Consultancy, both independent qualified persons within the meaning of National

Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and

contributing original co-authors of the February 2021 technical report. The Company has

also appointed Mark Gallagher, Btech, FSIAMM of MSG Consulting of South Africa, an

independent qualified person within the meaning of NI 43-101, for the purposes of Section

16 (Mining Methods) of the Amended Report.

The Amended Report dated January 8, 2024 maintains an effective date of February 1,

2021 and is available on SEDAR+ (www.sedarplus.ca) under Koryx's profile and on the

Company’s web site (www.koryxcopper.com).

The principal modifications to the Amended Report are as follows: (i) adding a pit

constraint in the mineral resource estimation, (ii) adding details to support the choice of

the cut-off grade, (iii) removing 5 metal extraction options in order to keep only one base

case, (iv) modifying the recommendations to propose to proceed with a pre-feasibility

instead of moving forward immediately with a feasibility study, and (v) removing all the

Appendixes attached the original February 2021 technical report.

A summary of the PEA highlights is provided in Table 1.

Note: The PEA is based only on the estimated indicated resource and the inferred resource are not part

of this economic assessment

Please note that mineral resources that are not mineral reserves do not have

demonstrated economic viability. Mineral resource estimates do not account for

mineability, selectivity, mining loss and dilution. These mineral resource estimates are

based on Indicated Mineral Resources that are considered too speculative geologically to

have the economic considerations applied to them that would enable them to be

categorized as mineral reserves. However, there is no certainty that these indicated

mineral resources will be converted to measured categories through further drilling, or into

mineral reserves, once economic considerations are applied. There is no certainty that the

preliminary economic assessment will be realized.

Qualified Person

Damian E.G. Connelly, BSc (Applied Science), FAusIMM, CP (Met), Principal Consulting

Engineer of METS Engineering Group is one of the main authors of the Amended Report

and is responsible for the technical part of this press release and is the designated

Qualified Person under the terms of NI 43-101.
