Koryx Copper Inc. says its ongoing infill and expansion drilling at the Haib Copper Project continues to confirm the scale, continuity and robustness of the deposit, with wide copper-equivalent intersections reported across multiple target areas as the company prepares an updated mineral resource estimate.
The latest results cover 13 diamond drill holes totalling 4,965 metres from the Phase 2 and Phase 3 drilling programme, aimed at tightening drill spacing within known mineralisation and testing lateral extensions of the planned open pit.
Among the most significant results, hole HM112 intersected 602 metres grading 0.32% copper equivalent (CuEq), including 272 metres at 0.44% CuEq and a higher-grade core of 40 metres at 0.50% CuEq.
HM121 returned 495 metres at 0.31% CuEq, including 284 metres at 0.42% CuEq, while HM117 delivered 184 metres at 0.51% CuEq, with multiple higher-grade intervals exceeding 1% CuEq.
The drill program has been planned to achieve a comprehensive conversion of all mineral resources from the Inferred to the Indicated category resource in order for all of the material to qualify for the PFS study update in the second half of 2026.
This entire drill program comprises 55,000m to be completed by the end of July 2026 to allow time for the assaying and updated resource modelling in 2026 Q3.
Koryx CEO Heye Daun said the latest drilling continues to validate both the size and consistency of mineralisation at Haib as the company advances towards feasibility.
“These latest assay results once again demonstrate and confirm the size, grade and robust copper mineralisation of the Haib deposit, with some excellent, wide and very consistent intercepts across multiple areas of the envisaged open pit,” Daun said.
He said the intersection widths and grades returned from both infill and step-out drilling further strengthen the project’s resource base and underpin confidence in the development strategy.
“The results highlight the ongoing success of our drill programme as we progress the technical work towards the highly anticipated pre-feasibility study targeted for late 2026,” Daun said.
Koryx said infill drilling has generally exceeded expectations in both intersection width and grade, while step-out holes have confirmed the presence of a broad, lower-grade mineralised halo surrounding higher-grade cores, supporting a large-scale open-pit development model.
Twelve drill rigs are currently active on site, with additional track-mounted rigs being mobilised to accelerate drilling.
Updated geological modelling, grade estimation, and the inclusion of molybdenum and gold as by-products have been completed, along with delineation of a large low-grade halo.
An updated Mineral Resource Estimate is expected to be published shortly, with the company targeting conversion of the entire resource to Indicated status by mid-2026.
Extensive metallurgical test work and infrastructure studies are ongoing ahead of a planned Pre-Feasibility Study towards the end of 2026.
Haib is an advanced, large-scale open-pit sulphide copper-molybdenum-gold porphyry project.
A Preliminary Economic Assessment released in September 2025 outlined average annual production of about 88,000 tonnes of copper in concentrate over a 24-year mine life, positioning Haib among Namibia’s most significant undeveloped copper assets.
