Koryx Copper Provides Update on Zambia Projects, Results of Regional Surface Geochemistry and Planning for the Upcoming Field Season

Koryx Copper S.A. announced that initial consent was granted for the transfer of the two earn-in licences to Koryx Zambia. The process to transfer the licenses into the Company’s Zambia registered wholly owned subsidiary is ongoing, with initial consent for the transfers having been received from the Director of Mining and Non-Mining Rights. The Company currently owns 51% of the licenses and has an option to earn up to 80% with an additional USD 2 million expenditure over the next 18 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. Koryx Copper S.A. (“Koryx” or the "Company") (TSX:KRY.V) (NSX:KYX) (OTCQB:KRYXF) is pleased to provide an update on exploration results and progress 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 “Project”). 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. Mpongwe Project Results from soil sampling carried out in late 2025 have been compiled and interpreted along with historical data. A total of approximately 4,000 soil samples (excluding Quality Assurance and Quality Control (“QAQC”) samples) were collected and analysed by Inductively Coupled Plasma Optical (Atomic) Emission Spectrometry (ICP-OES) for a suite of 33 elements. The sampling was carried out with three different aims and sample spacings: Repeat sampling over historical soil sampling points to confirm historical surface geochemistry data, carried out on selected lines at a sample spacing of 50m at Lwabufubu target and the area of previous diamond drilling in the northeast of the licence. Regional sampling targeting interpreted Upper Roan Group rocks and the contact zone with the underlying Lower Roan Group at 250m x 250m sample spacing. Regional sampling at 500m x 500m spacing testing the large areas of low-lying relief and drainages interpreted as Lower Roan Group and possible shallow or sub-cropping basement lithologies. Outcrop over the licence area is poor and interpretations of the underlying geology have been driven by a few isolated outcrops, historical geophysical data (magnetics, radiometrics and airborne electromagnetics) and to some extent satellite imagery. Multi-element geochemistry data from the 2025 soil sampling has augmented these interpretations and refined our understanding of the potential for Cu mineralisation. The map below shows the sampling undertaken in 2025 and the key outcomes of the results using gridded raw Cu values plotted on first vertical derivative airborne magnetics data. Also shown are the samples impacted by drainages (known locally as dambos), particularly in the lower parts of the interpreted Upper Roan stratigraphy. These low lying areas are interpreted to be related to preferential weathering of carbonate and gabbroic rocks. Additional sampling was trialled using Intertek’s Terraleach™ partial leach analytical technique over areas of known low-level Cu anomalism (in the two diamond drillholes in the northeast of the licence), and along selected lines at the Lwabufubu target area. The specific leach selected is designed for use in high iron-manganese regolith conditions, such as those encountered in the lateritic overburden found over the licence area. Results were equivocal, with conventional ICP-OES analyses generally giving better anomaly discrimination and more consistent identification of Cu anomalism. In general, the sampling indicates that conventional soils and ICP analyses are suitable in this environment where soils, even where laterite is developed, are residual in nature. The 2025 soil geochemistry results: Confirmed the Cu anomalism in the Lwabufubu target area. Highlighted additional areas of Cu anomalism along strike to the southwest. Screened large areas of Lower Roan stratigraphy where only limited follow up will be required. Lwabufubu Target Confirmation sampling validated historical surface geochemistry data and indicated that the results were comparable for the suite of elements sampled previously (Cu, Co, Mn, Ni, Pb, Zn), with means, minimum and maximum values and correlation between the datasets almost identical. The combined data defines a priority target with patchy, but consistent Cu anomalism coincident with de-magnetisation over 2,500m x 1,500m, within a larger target area of Cu anomalism of 5,500m x 2,500m. The Cu:Sc ratios for the 2025 check samples carried out over selected lines at Lwabufubu suggest that most of the elevated Cu values defining the target are not from gabbroic sources and warrant further work to assess the possibility that they are associated with Cu mineralisation (as shown in the map below). Additional anomalies detected with regional 250m x 250m – Upper Roan Isolated outcrop and the airborne geophysics indicates that the lower part of the Upper Roan in the licence area contains abundant mafic /gabbroic intrusive rocks (indicated by a mottled high magnetic signature). In addition, minor ironstone outcrops and float have been observed in these areas. It is also likely that these areas are underlain by carbonate rocks, giving rise to lower relief dambo and pooled drainage areas. The 2025 sampling identified two areas with elevated Cu values which also show Cu:Sc ratios suggesting a possible source other than mafic /gabbroic intrusive rocks. The peak Cu values are in the range 190-223ppm, similar to those at Lwabufubu and warrant further work. The map below shows the significant influence of dambos in the areas around these two areas (labelled as MP1 and MP2). Additional elevated Cu:Sc ratio values occur in areas east and northeast of Lwabufubu which are associated with relatively low Cu values (up to 73ppm) warrant checking in the field prior to possible follow up. Regional 500m x 500m sampling over Lower Roan Group (and possible Basement) The widely spaced sampling over the poorly exposed, low-lying and generally magnetically quiet interpreted Lower Roan Group sedimentary rocks and possible Basement lithologies has largely screened these areas and little follow up is required.
