Vancouver, B.C., Canada – February 23, 2026 – Koryx Copper Inc. (“ Koryx” or the " Company") (TSX:KRY.V)
(NSX:KYX) (OTCQB:KRYXF) is pleased to announce assay results from 13 drill holes (4,960m) received as part
of the Phase 2 and 3 infill and expansion drill program for its 2026 exploration and project development
strategy on the wholly-owned Haib Copper Project (“Haib” or the “Project”) in southern Namibia.
Haib is an advanced, large-scale open-pit sulphide Cu/Mo/Au porphyry project that is envisaged to produce at
an average of 88 ,000tpa of Cu in concentrate over a 24 -year mine life via a simple, scalable, open pit
crushing/milling/flotation process . The Company's Preliminary Economic Assessment (“ PEA”) dated 4
September 2025 d emonstrated the project to be technically and economically feasible with attractive
economics and a simple, scalable, long -life and low -cost development strategy undergoing rapid
advancement.
Heye Daun, Koryx Copper’s President and CEO commented: “These latest assay results once -again
demonstrate and confirm the size, grade and robust copper mineralization of the Haib deposit with some
excellent, wide and very consistent intercepts across multiple areas of the envisaged open pit. The encouraging
intersection widths and grades in the in-fill as well as step-out holes further strengthens the resource base.
These results demonstrate the ongoing success of our drill program as we progress the technical work towards
the highly anticipated PFS to be published in late 2026.”

Discussion of Drill Results
Thirteen drillholes are reported across the main mineralised zone at Haib, comprising three holes in Target 1,
three in Target 2, five in Target 3 and two in Target 4. Four of these holes are classified as in -fill drillholes,
designed to reduce sample spacing within known mineralisation, while the remaining nine are peripheral step-
out holes intended to test the lateral extent of Cu mineralisation.
Results from the in -fill holes are better than anticipated, with both intersection widths and Cu grades
exceeding expectations. The two holes drilled in the northern part of Target 3 and the two in the southeastern
part of Target 2 tested conceptual grade extensions; although Cu grades were low, the implications for the
mineral resource are considered negligible. The remaining step-out holes returned results ranging from slightly
positive to highly encouraging, particularly in the eastern part of Target 1 a nd the southeastern sector of
Target 3.

1. True widths are unknown. 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).
2. Mineral Resource (MRE) copper equivalent (CuEq%) values have been calculated using commodity type and price considering the relevant recovery
rate. The following metal prices were used Cu US$4.54/lb; Mo US$22.68/lb; Au US$4,000/oz along with the following recoveries indicated from
test work, Cu 89%; Mo 65% and Au 50%. The CuEq was then calculated using CuEq = [(Cu grade/100 * 0.89 Cu recovery * 2204.62 * $4.54 Cu
price/lb) + (Mo ppm/1000000 * 0.65 Mo recovery * 2204.62 * $22.68 Mo price/lb) + (Au grade * 0.50 Au recovery * 4000 Au price/oz / 31.1035)]
/ [0.89 Cu Recovery * 2204.62 * $4.54 Cu price/lb]
Target 1 Results
HM114 was drilled in the southeastern part of Target 1 to reduce sample spacing in this area. Results are
broadly consistent with expectations, with the known Cu mineralised zones successfully intersected; however,
the upper high-grade zone from 28m downhole proved to be approximately 25m wider than anticipated. Of
additional interest is an 8 m wide interval encountered at 88m downhole, averaging >0.1g/t Au, together with
a further three samples between 140m and 312m returning grades exceeding 0.1g/t Au. Tungsten (W) is also
present, with sporadic samples exceeding 100ppm and a peak value of 3,700 ppm recorded in a single sample.
HM115 is located 50m south of HM114 and returned results consistent with the current mineralisation model
for Target 1, characterised by shallow -dipping zones. Two mineralised intervals intersected below 340m
downhole (10m at 0.5% Cu and 8m at 0.91% Cu) exceed expectations in both thickness and grade. Gold grades
are also elevated, with three samples between 110m and 172m downhole returning values of approximately
0.4 g/t Au.
HM117 is located 50m west of the two preceding boreholes and was drilled to reduce sample spacing in this
area. Results are in line with expectations, with the upper 150m of the hole intersecting eight mineralised
zones ranging from 2m to 16m in thickness and averaging between 0.5% and 4.1% Cu, the latter representing
the highest Cu grade encountered to date at Haib. Deeper intersections of 16m at 0.42% Cu and 30m at 0.45%
Cu represent significantly better-than-anticipated mineralisation at depth. Gold values remain elevated, with
a 28 m wide zone from surface averaging just under 0.1 g/t Au.
Target 2 Results
HM108 was collared in the eastern part of Target 2 to test Cu mineralisation indicated by historical drilling.
Copper grades are broadly in line with expectations; however, the higher -grade intersections around 120m
downhole, suggested by historical data, proved to be both thinner and lower grade than predicted.
- 6 -
Molybdenum is essentially absent, while gold is present in a 10m wide interval from 18m downhole, averaging
just under 0.1 g/t Au.
HM118 was drilled on the eastern periphery of Target 2 to test the potential for resource extension in this
area. The hole returned uniformly low Cu, Mo and Au grades, indicating that mineralisation at Haib does not
extend into this location.
HM120 is located in the southern part of Target 2 and was drilled to define the boundary of higher -grade Cu
mineralisation in this area. Although substantial portions of the hole returned Cu grades exceeding 0.2%,
intersections grading above 0.3% Cu are limited. Molybdenum is present at elevated levels, with at least five
discrete mineralised zones identified, the widest averaging 158ppm Mo over 88m. Gold is absent; however,
tungsten values exceeding 100ppm are relatively common, including intersections of 2,470ppm W over 2m
and 1,360ppm W over 2m.
Target 3 Results
HM110 and HM116 were drilled 87m apart on the same section in the eastern part of Target 3. Historical hole
HM064, located approximately 140m south of HM110, intersected significant mineralisation, and these two
holes were designed to test the up-dip extension of this mineralisation towards surface.
Both HM110 and HM116 returned no significant Cu or associated mineralisation, indicating that they lie
outside the main mineralised envelope at Haib. A large -scale, interpreted sub -vertical shear zone has been
mapped between HM110 and HM064. At Haib, shear zones are commonly associated with depletion of Cu,
and it is therefore interpreted that the mineralisation intersected in HM064 terminates against or near this
structure.
HM121 and HM111 were drilled north of, and on the same section as, previously reported holes HM090 and
HM006 in the southeastern part of Target 3. HM090 and HM006 returned the widest near-surface high-grade
Cu intersections (>1% Cu) encountered at Haib, an d the new holes were designed to test the north ern
extension of this mineralisation.
Structural complexity is evident in this area, characterised by an east –west striking, broad, sub-vertical zone
of intense alteration mapped between HM090 and HM121 and associated with depletion of Cu. This is
reflected in the upper 88m of HM121, which averages only 0.06% Cu, with molybdenum absent. Beyond this
depth and outside the alteration zone, Cu grades increase rapidly, culminating in a 284m interval of
mineralisation averaging just under 0.4% Cu.
HM111, located 80 m north of HM121, returned comparable results. The upper 120 m of the hole averages
0.07% Cu, followed by a higher-grade interval of 64 m averaging 0.38% Cu. The hole was terminated while still
in mineralisation and should be extended to fully define the depth extent of this zone. Spatial comparison of
the high -grade intersections in HM006/HM090 and HM121/HM111 suggests that the zone of intense
alteration is associated with a normal fault exhibiting up to approximately 150 m of vertical displacement.
HM112 was collared on the boundary between the Target 3 and Target 4 mineralised domains and drilled
northwards to intersect the main Target 3 mineralisation at depth. Results indicate a broad zone from surface
grading >0.3% Cu; however, Cu grades decrease to below 0.2% for the subsequent ~130m before defining a
17 m interval averaging 0.35% Cu. This includes higher-grade sub-intervals such as 16m at 0.54% Cu and 40m
at 0.45% Cu.
Molybdenum is present at significant levels throughout this 172 m interval and extends into the footwall,
averaging 196ppm Mo over 292m, with multiple samples exceeding 1,000ppm and a peak value of 5,200 ppm.
- 7 -
Tungsten is also present, with a 32m interval averaging 450ppm W, including 4m at 1,640 ppm. Gold values
are elevated locally, with a 2m sample returning 0.42 g/t Au.
Target 4 Results
HM109 was drilled well south of Target 4, progressing northwards to intersect previously identified Cu zones
at depth. A shallow Cu zone exceeding 0.3% was confirmed, consistent with earlier drilling results. Deeper
extensions of Cu mineralization are pres ent but occur as thinner intervals with lower grades. Molybdenum
(Mo) is notably elevated, averaging 279ppm from surface over 76m, including a high-grade interval of 8 m at
1,007 ppm. While the average Cu grade of this first 76m is 0.22%, these Mo grades r aise the CuEq to 0.35%
over this interval. Starting at a downhole depth of 26m, Au mineralization averages 0.15g/t over 10 m, with
one sample returning 0.52g/t. Additional Au assays above 0.2g/t were also encountered at greater depths.
HM113, located 75m east of HM109, was drilled for the same objectives. Results are broadly comparable to
HM109, though Cu grades are more continuous, averaging between 0.25 –0.30%. Ten mineralized zones,
ranging from 2m to 6m in width, returned grades of 0.30–0.35% Cu. These results indicate a reduction in grade
with depth within the shallower Cu zones of Target 4. Molybdenum (Mo) is also present at elevated levels,
with a 92 m interval from 24m downhole averaging 144 ppm.
Updated Drill Program
The drill program has been planned to achieve a comprehensive conversion of all mineral resources from the
Inferred to the Indicated category resource in order for all of the material to qualify for the PFS study update
in the second half of 2026. This entire drill program comprises 55,000m to be completed by the end of Ju ly
2026 to allow time for the assaying and updated resource modelling in 2026 Q3.
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 analysed 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.

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.
