Koryx Copper Files an Amended PEA for Its Haib Copper Project
VANCOUVER, British Columbia, Jan. 22, 2024 (GLOBE NEWSWIRE) — 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.

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.
