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: • HM155: 831m @ 0.27% CuEq (95ppm Mo, 0.018g/t Au) (0 – 831m) incl. 244m @ 0.42% CuEq (536 – 780m) • HM147: 654m @ 0.25% CuEq (33ppm Mo, 0.019g/t Au) (0 – 654m) incl. 84m @ 0.47% CuEq (4 – 88m) incl. 12m @ 0.79% CuEq and 46m @ 0.47% CuEq (234 – 280m) • HMRC008: 231m @ 0.44% CuEq (24ppm Mo, 0.037g/t Au) (0 – 231m) incl. 12m @ 2.55% CuEq (0 – 12m) and 10m @ 0.61% CuEq (190 – 200m) and 14m @ 0.47% CuEq (216 – 230m) • HM152: 578m @ 0.25% CuEq (51ppm Mo, 0.013g/t Au) (0 – 578m) incl. 14m @ 0.59% CuEq (84 – 98m) and 16m @ 0.36% CuEq (282 – 298m) and 42m @ 0.33% CuEq (412 – 454m) • HM139: 466m @ 0.26% CuEq (38ppm Mo, 0.025g/t Au) (0 – 466m) incl. 76m @ 0.52% CuEq (140 – 216m) incl. 14m @ 0.70% CuEq and 14m @ 0.37% CuEq (318 – 332m) • HM146: 497m @ 0.22% CuEq (43ppm Mo, 0.023g/t Au) (0 – 497m) incl. 20m @ 0.44% CuEq (234 – 254m) and 62m @ 0.37% CuEq (354 – 416m) incl. 10m @ 0.47% CuEq • HM134: 605m @ 0.21% CuEq (47ppm Mo, 0.021g/t Au) (0 – 605m) incl. 20m @ 0.54% CuEq (248 – 268m) and 10m @ 0.42% CuEq (362 – 372m) and 10m @ 0.55% CuEq (444 – 454m) 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 cath...
