Koryx Copper drills further results at Haib copper project, Namibia

Highlights

Assay results reported for 15 drill holes comprising 6,825m of infill and expansion drilling.

Consistent, wide intercepts incl. 318m @ 0.49% CuEq (162 – 480m) and 220m @ 0.40% CuEq (32-252m) with higher grades across multiple holes (incl. 12m @ 2.55% CuEq (from surface), 10m @ 1.78% CuEq and 32m @ 1.06% (from 224m)) - among the best grades drilled at Haib to date.

Best 6 of 15 drill hole assay intersections as follows:

LUXEMBOURG, Sept. 09, 2026 (GLOBE NEWSWIRE) -- Koryx Copper S.A. (TSX:KRY.V) (NSX:KYX) (OTCQX:KRYXF) (“ Koryx ” or the " Company ") is pleased to announce assay results from 15 drill holes (6,825m) received as part of the ongoing infill and expansion drill program on the wholly-owned Haib Copper Project (“ Haib ” or the “ Project ”) in southern Namibia.

Haib is a massive, disseminated porphyry Cu/Mo/Au deposit and is envisaged to produce a Cu and Mo concentrate via large-scale open pit mining and conventional sulphide milling and flotation.

Heye Daun, Koryx Copper’s President & CEO commented: “We continue to receive excellent drill assay results from our PFS infill drill program which has recently concluded. Once again, most of the drill results display very wide intercepts, including some high grades from surface. Whilst drilling has completed, assay results are still coming in and further results are expected in the next few weeks. The geological modelling and estimation for the updated MRE and PFS has commenced and we are on track to publish an MRE update and PFS study results before the end of 2026. We are very excited about how the PFS technical work is unfolding and we expect the PFS to describe a significantly optimized and improved project scope with corresponding improvements in the technical and economic metrics of the Haib copper project.”
