Koryx Copper Provides Update on Zambia Projects

and Planned 2025 Exploration Work Program

Highlights

• Koryx Copper owns 51% of two highly prospective exploration licenses in the Zambian copper belt,

with an option to earn up to 80% over the next 30 months.

• Over the last few months significant work was completed in preparation for the commencement of

exploration activities on the 2 licenses, in particular:

o Initiated preparations for drone magnetics to be flown in April over Luanshya West license.

o Obtained significant historical datasets covering the Mpongwe license.

o Field work to commence imminently in April after rainy season.

• Budget of approximately US$1.2 million planned for 2025 Zambia work programs.

• Commenced process to transfer licenses into majority-owned local subsidiary.

Vancouver, B.C., Canada – April 8, 2025 – Koryx Copper Inc. (“Koryx” or the " Company") (TSX -V: KRY) is

pleased to provide an update on work programs planned for the 2025 field season on its two large scale

exploration licences in Zambia, namely the Luanshya West project (LEL 23246, 54 km2) and Mpongwe project

(LEL 23248, 675 km2) (the “Projects”).

Koryx holds the option to acquire up to 80% of the Projects in the Copperbelt in Zambia. The Zambian

Copperbelt makes up part of the larger Central African Copperbelt (CACB) which extends north into the

Democratic Republic of Congo. The CACB is the world’s largest sedimentary rock hosted stratiform copper

province and includes at least 14 giant deposits such as First Quantum Mineral’s Kansanshi and Sentinel, as

well as Ivanhoe’s Kamoa and Kakula.

The licenses cover approximately 745 km2 in the heart of the Zambian Copperbelt, close to the western margin

of the Kafue Anticline which hosts numerous significant copper deposits.

Heye Daun, Koryx Copper’s President and CEO commented: "We are very excited that after many months of

systematic preparatory work, including site visits, data reviews, strengthening existing relationships and

developing new ones, we are now in a position to commence with an exciting exploration program on our

Zambian licenses. This program builds on the valuable work done previously and it is significantly enhanced by

a wealth of historical data which our exploration team has been able to source, and which we have spent the

last few months interpreting. Once the rainy season ends in the next few weeks, we expect to build on this with

a significant field work program, incl uding drill testing some of the targets which we have identified. The

Zambian copper belt continues to be one of the world’s hottest copper exploration jurisdictions, and we are

very excited to be adding value to our Zambian portfolio. This is in addition to the ongoing development of our

world-class, large-scale and open pit Haib copper deposit in Namibia, which continues to be Koryx flagship

asset.”

2025 Zambia Work Program

The Company has used the summer rainy season to compile and re-interpret previous exploration data for the

Luanshya West project and to source and obtain historical exploration data for the Mpongwe project, allowing

the implementation of systematic exploration programs in 2025. The Company has allocated approximately

US$1.2 million for the exploration programs in Zambia, split equally between the two project areas.

Luanshya West Project

The project is located on the southeastern margin of the area known as the Chambishi or Kakontwe sub-basin

where Lower and Upper Roan Subgroup rocks onlap onto the basement dome of the Kafue Anticline.

Mineralisation along strike to the immediate northeast includes known deposits at Chibuluma and Chifupu.

The Lower Roan rocks host most of the mineralisation in the area around the Chambishi basin and specifically

within the footwall arenites. Additional prospectivity is interpreted in the licen se area at the upper contact

zone between the Mwashya Subgroup and lower Nguba Subgroup rocks.

A drone-mounted airborne magnetic survey is planned in early April to cover the entire Luanshya West license

area. The detailed magnetic data interpretation will better constrain the basin margins (Lower Roan rocks)

and possible structural controls on mineralisation.

This will augment previously reported soil geochemistry and induced polarization (IP) / resistivity surveys

carried out by the Company , which identified several targets worthy of follow up, but did not systematically

cover or assess the prospectivity of the entire license area; see Figure 1 below.

Figure 1: Luanshya West project – summary of previous work by the Company highlighting coincident IP chargeability and soil

geochemistry anomalies, but also gaps in the coverage of the work, and scope for additional follow up prior to drilling.

Initial reconnaissance field follow up and regolith mapping will take place concurrently with the airborne

magnetic survey and interpretation.

Additional surface or shallow geochemical sampling and ground geophysics will be carried out in areas not

tested by previous work to define further drill targets for testing in late 2025.

Mpongwe Project

The project overlies the southern half of one of the lesser-known basement domes, the Mpongwe or Kabuche

Dome, situated to the southwest of the Kafue Anticline and about 80 km southwest of the Luanshya mine.

The Company has sourced and obtained extensive historical datasets covering the Mpongwe project area. The

data is largely from the period 2008 to 2012 (Mukuba Resources), but also earlier work by Anglo American and

Equinox Minerals in the 1990’s.

Figure 2: Mpongwe project – historical first vertical derivative magnetics data overlain with historical soil geochemistry (copper)

geochemistry data. Note soil geochemistry data has not been verified and is for indication purposes only.

The data includes detailed helicopter -borne magnetic and radiometric, and electromagnetic surveys as well

as extensive surface geochemistry and drilling information from limited drill testing done by the previous

explorers.

Importantly, the historical data will allow the Company to accelerate exploration and targeting on this large

area which remains untested by systematic sub-surface sampling, either by pitting/trenching or drilling.

Rock exposures in the Mpongwe project area are poor, and initial work will focus on validating historical

geochemistry data and regolith mapping.

Repeat sampling will be carried out where necessary, and in-fill sampling in areas where little work has been

done previously. Follow up pitting/trenching and/or shallow (percussion/aircore) drilling and ground

geophysical surveys are likely prior to diamond drill testing of targets in Q4-2025.

The Lwabufubu target was identified by historical work, but was never drill tested. The Company will focus

some of the early work in 2025 on this target to assess whether it can be fast-tracked for drill testing. Figure 2

above shows the location of the Lwabufubu target, the location of the only known drilling (in the northeast),

and the extensive, but quite selective historical sampling in the project area.

License Ownership

In addition to the work planned for the Luanshya West and Mpongwe projects, the Company has also initiated

the process to transfer the licenses into a Zambia registered wholly owned subsidiary of Koryx. The Company

currently owns 51% of the licenses and has an option to earn up to 80% with an additional US$3 million

expenditure over the next 30 months. The Company has retained legal counsel in Zambia to assist with the

official lodging of documentation with the Ministry of Mines and Minerals Development in Zambia.

RSU Issuance

The Company has approved the grant of up to an aggregate of 2 ,750,000 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, or the cash equivalent thereof based on the fair market

value of the shares of the Company calculated in accordance with the terms of the Omnibus Plan.

The grant of RSUs is subject to disinterested shareholder approval of the Company’s new Omnibus Plan at the

AGM on May 22, 2025, and is subject to any necessary regulatory approvals and requirements of the Exchange.

Appointment of Chairman

In addition, the Company announces the appointment of Mr. Alan Friedman as Chairman effective April 7,

2025, replacing Mr. Heye Daun who will retain the positions of President and Chief Executive Officer of the

Company. Mr. Friedman will remain as Director in an independent capacity.

About Koryx Copper Inc.

Koryx Copper Inc. is a Canadian copper development Company focused on advancing the 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 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 1970’s with significant exploration programs led by companies including

- 5 -

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 1,136Mt 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 . 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.
