Koryx Copper president and chief executive officer Heye Daun says the latest drilling at the Haib Copper Project has confirmed the consistency of copper mineralisation across the deposit, while also identifying localised higher-grade zones that could enhance future mine scheduling as the project advances toward pre-feasibility in southern Namibia.
The comments follow the release of assay results from nine diamond drill holes totalling 4,007 metres, completed as part of Koryx’s Phase 2 and Phase 3 drilling programmes at the wholly owned Haib project.
The results continue a pattern established throughout 2025, in which successive drilling campaigns have consistently returned wide, continuous copper intersections across multiple target areas, reinforcing confidence in the scale and predictability of the porphyry system.
Among the latest notable intercepts were 74 metres grading 0.36% copper in hole HM103, including a higher-grade interval of 16 metres at 0.56% copper, and 19 metres at 0.64% copper in hole HM102.
Hole HM104 returned several mineralised intervals, including a broad 214-metre intersection averaging 0.34% copper, while HM101 intersected 62 metres at 0.31% copper from surface and a further 66 metres at 0.37% copper at depth.
Additional drilling delivered intersections such as 56 metres at 0.33% copper in HM98 and 66 metres at 0.32% copper in HM105, supporting the continuity of mineralisation across the project area.
These results build on a steady flow of drilling updates released earlier in the year.
In May 2025, Koryx reported assays from 12 holes totalling 3,603 metres, including exceptionally broad mineralised intervals extending hundreds of metres downhole, within which multiple higher-grade zones above 0.40% copper were identified.
July drilling results further confirmed long continuous intersections, including zones exceeding 200 metres at grades in the mid-0.30% copper range, as well as shorter higher-grade intervals approaching or exceeding 1% copper.
In September, the company reported one of the strongest individual results recorded at Haib, with a single hole intersecting more than 100 metres of continuous mineralisation grading about 0.70% copper from surface within a much broader mineralised envelope.
Subsequent results released in August and October added further infill and step-out data, confirming that mineralisation remains open laterally and at depth while tightening confidence ahead of a mineral resource update.
Haib is an advanced-stage open-pit porphyry copper project with associated gold and molybdenum mineralisation.
The deposit is envisaged as a conventional crushing, milling and flotation operation producing a copper concentrate, with potential upside from additional copper recovery through heap leaching.
Its large geological footprint, technical simplicity and location within Namibia’s stable mining jurisdiction underpin its long-life development potential.
The latest drilling targeted a combination of infill positions and extensions around the margins of known higher-grade zones.
Several holes intersected copper mineralisation in areas previously outside the resource model, indicating potential incremental additions to overall tonnage.
In parts of the deposit, higher-grade mineralisation was confirmed to be closer to the surface than previously modelled.
At the same time, deeper drilling continued to intersect wide mineralised intervals, supporting the system’s depth continuity.
Daun says the results provide confidence not only in the grade consistency of the deposit, but also in opportunities to improve the project’s economic profile through mine planning.
He says the identification of localised higher-grade zones within the broader mineralised envelope creates scope to optimise early production schedules while maintaining the scale of the operation.
Drilling activity at Haib has intensified, with 12 rigs now operating on site. In addition to ongoing infill and expansion drilling, rigs are undertaking geotechnical programmes for pit wall stability and civil construction to support pre-feasibility study work already underway. These programmes are intended to de-risk future mine design and infrastructure planning.
Geological modelling and mineral resource estimation are continuing in parallel, with Koryx targeting the release of an updated mineral resource estimate before the end of January 2026.
The revised estimate is expected to incorporate gold and molybdenum by-product credits for the first time, alongside an enhanced geological interpretation informed by the expanded drilling database.
Engineering studies covering power and water supply, infrastructure development and transport logistics are progressing, while environmental, mining and land access permitting activities continue within Namibia’s established regulatory framework.
Koryx says these parallel work streams are positioning Haib to transition from an advanced exploration asset into a defined development project within the country’s growing copper sector.
