Koryx Copper Announces Further Significant Drill Results at the Haib Copper Project, Southern Namibia Highlights Assay results reported for a further 13 drill holes for 4,965m of infill & expansion diamond drilling. Notable, selected drill intercepts from the holes include: HM112: 602m @ 0.32% CuEq incl. 272m @ 0.44% CuEq incl. 40m @ 0.50% CuEq HM121: 495m @ 0.31% CuEq incl. 284m @ 0.42% CuEq HM117: 184m @ 0.51% CuEq (12 - 196m) incl. 16m @ 1.09% CuEq16m @ 0.46% CuEq (268 - 284m)30m @ 0.51% CuEq (300 - 330m) HM111: 64m @ 0.42% CuEq (154 - 218m) incl. 6m @ 0.74% CuEq HM114: 66m @ 0.40% CuEq (28 - 94m) HM115: 30m @ 0.52% CuEq (162 - 192m)38m @ 0.63% CuEq (264 - to 302m) HM108: 18m @ 0.34% CuEq (24 - 42m) HM109: 8m @ 0.60% CuEq (30 - 38m)10m @ 0.42% CuEq (84 - 94m)18m @ 0.42% CuEq (402 - 420m) 12 drill rigs active on site. Additional track mounted rigs (faster drilling & faster moves between holes) are being mobilised in order to accelerate the drill program.Updated geological modelling, grade estimation, inclusion of molybdenum (Mo) & gold (Au) by-products and the delineation of a large low grade halo has been completed. Updated MRE expected to be published shortly, reflecting these improvements. Drilling is ongoing with the objective of converting the entire MRE to Indicated status by mid-2026. Extensive metallurgical testwork and technical/infrastructure studies ongoing towards the planned publication of a PFS towards the end of 2026. VANCOUVER, British Columbia, Feb. 23, 2026 (GLOBE NEWSWIRE) -- 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 demonstrated 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.” Figure 1: Plan view indicating recent drill hole locations. Results indicated in black are shown on the long section below Figure 2. Long section showing thirteen drillhole intersections relative to the model for Cu mineralization 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 and the southeastern sector of Target 3.
