KORYX COPPER DRILLS WIDEST HISTORIC CONTINUOUS HIGH-GRADE ZONE
110M @ 0.70% CU (TRUE WIDTHS UNKNOWN)
EPL 3140 LICENSE RENEWAL
SUBMISSION OF MINING LICENSE APPLICATION
AT THE HAIB COPPER PROJECT, SOUTHERN NAMIBIA
Highlights
• Drillhole HM90 intersects 110m @ 0.70% Cu (0 to 110m), incl. 36m @ 1.42% Cu (28 to 64m) within
a wider envelope of 417m @ 0.33% Cu.
• This represents the widest continuous high-grade zone (>1% Cu) encountered at Haib to date.
• HM90 results are located 60m from previously reported HM06 (90m at 0.60% Cu, including 36m at
0.88% Cu – open at depth) indicating a robust area of high -grade mineralisation at surface in the
Target 2 area.
• Namibia’s Ministry of Mines approves the renewal application for Exclusive Prospecting License
3140 (EPL 3140). This EPL underlies the Haib project and renewal of this license is testament to the
Koryx team’s execution track record in Namibia.
• Mining Licence (“ML”) application for the Haib project submitted to Namibia’s Ministry of Mines,
thereby further securing the mineral rights tenure of the Haib project.
Vancouver, B.C., Canada – September 03, 2025 – Koryx Copper Inc. (“Koryx” or the "Company") (TSX-V: KRY)
is pleased to announce assay results from drill hole HM90 received as part of the Phase 3 drill program for its
2025 exploration and an update on the status of its mineral right tenure on the wholly-owned Haib Copper
Project (“Haib” or the “Project”) in southern Namibia.
Haib is an advanced -stage copper/molybdenum/gold project that is envisaged to produce a copper
concentrate via a conventional crushing/milling/flotation metallurgical process, with the potential for
additional copper production via heap leaching.
Heye Daun, Koryx Copper’s President and CEO commented: " I am very pleased by two unrelated but equally
significant developments at the Haib project. The first one is a very significant, high -grade drill result in drill
hole HM90, and the second one is the approval of our EPL renewal application for another 2 ye ars, in
conjunction with the submission of our mining license application.
On the first one: Drill hole HM90 was drilled to target the east -west structures related to breccias and shear
zones in the Volstruis river area of Target 2 and intersected 0.70% Cu from surface to a depth of over 110m
including 36m at 1.42% Cu. This is ve ry significant in proving the ability of the Haib deposit to produce such
high grades, but also to demonstrate the continuity of these structures along strike and their much higher
grade. Given the support provided by some neighboring high-grade holes (and still open at depth), this area is
opening up as a compellingly prospective target with the potential for near surface, high grade and low -strip
starter pit development along these east-west trending structures.
On the second one: We are very pleased with the approval of our renewal application for Exclusive Prospecting
License (EPL) 3140. As a management team with a proud track record in Namibia, we go to great lengths to
deliver on our promises, and the renewal of EPL3140 provides us with an opportunity to further de -risk the
project as we advance the project towards the next critical permitting steps, namely obtaining the
environmental and mining permits over the next year.”

Discussion of Drill Results
Target 2 Results
HM90 was drilled on the eastern margin of Target 2, just north of the Volstruis River, to reduce the sample
spacing and better define the eastern extent of mineralisation. The 419m hole returned an average grade of
0.33% Cu, including a high-grade 110m zone from surface grading 0.70% Cu. Below this, the remainder of the
hole averaged 0.20% Cu. Within the upper high-grade interval, a contiguous 36m section of breccias averaged
1.42% Cu, with a peak grade of 3% Cu. Mineralisation is almost entirely chal copyrite, and this intercept
represents the widest continuous high-grade zone (>1% Cu) encountered to date at Haib.

1. Widths are interval widths and not true widths. The reported intervals are calculated using the following parameters:
a. Only Cu (%) was used to determine the intervals
b. The target composite grade is ≥0.30% Cu.
c. Composites start and end with samples ≥0.30% Cu.
d. Grades between 0.20% and 0.30% are included in interval but generally constitute <40% of the interval.
e. Consecutive samples between 0.20% and 0.30% should be fewer than 5 samples (10m).
f. Grades below 0.20% are included but generally constitute <20% of the interval.
g. Consecutive grades <0.2% should be fewer than 2 samples (4m).
The 2021 Koryx drill hole HM06, located approximately 60m south of HM90, also intersected a high -grade
zone from surface, returning 90m at 0.6 0% Cu, including 36m at 0.88% Cu. HM06 was drilled by historical
exploration operators to a depth of 152m, stopping in mineralization, with the entire hole having a grade of
0.45% Cu. Other historical drillholes situated approximately 75 m east and west of HM90 similarly report near-
surface mineralisation at above the average MRE grades of 0.40% Cu. As such, the significantly higher-grade
results from HM90 and HM06 define a highly prospective target, the lateral continuity of which is not yet been
tested.
Permitting Update
Ministry Approves Renewal of EPL 3140 Application
The Koryx team submitted the application for the renewal of EPL 3140 to the Ministry of Industry, Mines and
Energy (“MIME”) on the 31 st March 2025. The application included a review of the fi eldwork and technical
update from the previous two years of work on the Haib Project including significant resource drilling and
metallurgical testwork programs. The application also confirmed that Koryx had satisfied the expenditure
commitments made for the previous EPL license period required for the renewal.
The MIME completed the review of the application and have subsequently granted the renewal of EPL 3140
for a further two years from the expiration of the previous permit. This validates the EPL until 6th July 2027
with standard requirements relating to the proposed work program and budget. Koryx also commits to make
a presentation to the ministry after the first year of the permit validity and obtain annual Environmental
Clearance Certificates (“ECC”) from the Ministry of Environment, Forestry and Tourism (“MEFT”).

Mining License Application Submitted to MIME
Haib Project technical studies show the Haib Project is feasible for development and, based on this, a Mining
License (“ML”) application has been submitted to convert the EPL to a ML. The application was submitted to
the ministry with a technical study update, guidance on the project development timeframe and Koryx’s
strategy of financing the mine development.
One of the conditions for granting of the Mining License will be an ECC for the mine development. The Koryx
team and specialist consultants are in the process of completing the required Environmental and Social Impact
Assessment (“ESIA”) for submission to MEFT in Q2 2026. This is one of the conditions to the granting of a
Mining License ECC. In parallel, the MIME is expected to take at least six months to evaluate the application,
and during the current prefeasibility study the Koryx team will continue to engage the ministry on technical
updates and key project milestones.
Having initiated the ML application, Koryx has strengthened its legal tenure to the mineral rights of the Haib
project. This transition is a necessary step to establish the legal basis for mining operations and demonstrates
the ability and intent of the Company to progress the Haib project to the next level of development.
Quality Control
All drill core was logged, photographed, and cut in half with a diamond saw. Half of the core was bagged and
sent to ALS Laboratories Ltd. in Johannesburg, South Africa for analysis (SANAS Accredited Testing Laboratory,
No. T0387) and ActLabs in Canada, while the other half was quartered with one quarter archived and stored
on site for verification and reference purposes while the other quarter will be used for metallurgical test work.
33 elements are analyzed by Induced Coupled Plasma (ICP) utilizing a 4-acid digestion and gold is assayed for
using a 30g fire assay method. Duplicate samples, blanks, and certified standards are included with every batch
and are actively used to ensure proper quality assurance and quality control (“QA/QC”) The QA/QC frequency
is 1 in 20 for each of blanks, duplicates and standards.

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 includi ng
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 alteratio n 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"). The Technical Report and other information is available on the Company's
