Koryx Copper has reported another strong set of drilling results from its Haib Copper Project in southern Namibia, with assays from 15 additional drill holes continuing to demonstrate broad, near-surface mineralisation ahead of an updated mineral resource estimate and the project’s pre-feasibility study (PFS).
The latest results cover 15 drill holes comprising 5,351 metres of infill drilling completed as part of the company’s ongoing 15-rig drilling campaign.
The programme returned consistent intercepts of up to 714 metres grading above the current average mineral resource estimate (MRE) copper-equivalent grade, while also identifying pockets of higher-grade gold, molybdenum, and tungsten mineralisation.
The results form part of Koryx’s strategy to upgrade and expand the Haib resource before completing a pre-feasibility study, which remains on schedule for publication before the end of 2026.
The standout intersection came from hole HM153, which intersected 714 metres grading 0.31% copper equivalent (CuEq) from surface, including 68 metres grading 0.54% CuEq and a further 82 metres grading 0.41% CuEq.
It represents the widest mineralised interval reported in the latest batch of drilling.
Another significant result came from hole HM138, which intersected 584 metres grading 0.34% CuEq, including 72 metres grading 0.48% CuEq, 128 metres grading 0.36% CuEq and 170 metres grading 0.42% CuEq, within which a 20-metre interval graded 0.70% CuEq.
The hole also recorded what the company described as the strongest gold mineralisation encountered at Haib to date, including 2 metres grading 1.96 grams per tonne gold within a broader 20-metre interval grading 0.423g/t gold.
Hole HM149 returned 428 metres grading 0.35% CuEq, while HM141 intersected 582 metres grading 0.25% CuEq, including 84 metres grading 0.52% CuEq and 58 metres grading 0.39% CuEq.
Reverse circulation hole HMRC001 produced 243 metres grading 0.40% CuEq, exceeding expectations for both copper and molybdenum.
At Target 1, drilling continued to confirm the continuity of the deposit’s higher-grade core. Hole HM137 intersected 162 metres grading 0.46% CuEq and also identified several tungsten-bearing intervals, including 4 metres grading 0.12% tungsten and 20 metres grading 0.03% tungsten within the first 100 metres of the hole.
The company said the presence of tungsten in the upper portions of the porphyry system remains under investigation because it is considered unusual in this geological setting.
Drilling also extended mineralisation southwards. Hole HM139 intersected 65 metres grading 0.55% CuEq, ending with the final 8 metres grading 1.13% copper and 0.14g/t gold.
The hole was stopped in mineralisation because of rig limitations and will be deepened during a future drilling campaign to test the southern extension of the deposit.
According to Koryx, the latest drilling confirms that the current resource model remains robust while identifying several opportunities for resource growth and conversion from inferred to indicated categories through closer drill spacing.
Several holes returned copper-equivalent grades exceeding 0.30% CuEq from the surface, reinforcing the potential for future large-scale open-pit mining.
Haib is one of the world’s oldest known porphyry copper deposits and is planned as a large-scale open-pit copper mine.
Molybdenum concentrates are produced through conventional crushing, milling, and flotation, with the additional potential to produce copper cathodes via oxide heap leaching. Koryx is simultaneously optimising the project’s process flowsheet to improve economics while reducing technical risk.
Commenting on the results, Koryx Copper President and Chief Executive Officer Heye Daun said the combination of broad mineralised intersections, higher copper-equivalent grades, and recently announced process flowsheet improvements should enhance the economics of the Haib project ahead of the pre-feasibility study.
With a 15-rig drilling campaign continuing across the project, Koryx expects additional assay results, an updated mineral resource estimate and the completion of the PFS before year-end.
