Koryx Copper reports drill results for Haib project, Namibia

Highlights

Assay results reported for 17 drill holes comprising over 6,430m of infill drilling.

Consistent, wide intercepts up to 831m in width, including a 244m interval @ 0.42% CuEq in HM155.

Highest Cu (8.01%) and Ag (60.5g/t) grades recorded at Haib to date, intersected from surface in HMRC008 from 4m to 6m.

Drilling is ongoing with 15 drill rigs, 7 of which are on double shift.

Technical studies and cost estimation ongoing towards planned PFS publication at the end of 2026.

Best 7 of 17 drill hole assay intersections as follows:

LUXEMBOURG, Aug. 14, 2026 (GLOBE NEWSWIRE) -- Koryx Copper S.A. (TSX:KRY.V) (NSX:KYX) (OTCQB:KRYXF) (“ Koryx ” or the " Company ") is pleased to announce assay results from 17 drill holes (6,430m) 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.

The Haib deposit is a massive, disseminated porphyry Cu deposit with associated Mo and Au. Haib is envisaged to produce a Cu and Mo concentrate via large-scale open pit mining and conventional sulphide milling and flotation with the potential for additional copper cathode production via oxide heap leaching. Ongoing process flow sheet optimization is aimed at improving project economics whilst reducing technical risk.

Heye Daun, Koryx Copper’s President and CEO commented: “These results stand out for their length as much as their grade. HM155 intersected 0.27% CuEq from surface to 831m including 244m at 0.42% CuEq, while HM139 and HM147 returned continuous zones of 76m at 0.52% CuEq and 84m at 0.47% CuEq, respectively, underscoring the scale and continuity of mineralization at Haib at good grades. By-product credits continue to strengthen the resource as well, with molybdenum and gold now joined by encouraging silver values, including our highest Ag grade at Haib to date.
