Noronex Limited says fresh drill assays from its ongoing 7,000-metre reverse-circulation programme have further expanded copper-silver mineralisation at the Powerline Project in eastern Namibia, strengthening confidence in the geological model underpinning exploration across the northern margin of the Kalahari Copper Belt.
The company said about 5,300 metres of drilling, covering 23 holes, has now been completed across the Steenbok, Qembo and Zambinda domes, with the programme funded under Noronex’s earn-in agreement with a wholly owned subsidiary of South32.
Drilling is now advancing eastward to test the Zambinda Dome, as results continue to validate the structural targeting strategy applied across the project area.
At the Qembo target, new intercepts confirmed copper-silver mineralisation along the prospective D’Kar–Ngwako Pan Formation contact.
Drillhole 25QBRC007 returned 4 metres grading 0.58% copper and 69 grams per tonne silver from 203 metres, while 25QBNRC008 intersected 3 metres at 0.29% copper and 48 grams per tonne silver from 211 metres.
Although several holes drilled on the southern limb and northern extensions did not return significant mineralisation, Noronex said these holes provided valuable structural information that will sharpen future targeting.
Further encouraging results were reported from the Steenbok Dome, where drilling continues to confirm continuity of mineralisation along the D’Kar–NPF contact.
Hole 25SBRC011 intersected 7 metres at 0.25% copper and 25 grams per tonne silver from 152 metres, while 25SBRC017 returned 9 metres at 0.24% copper and 29 grams per tonne silver from 226 metres.
Importantly, the mineralisation in 25SBRC011 correlates with a previously reported intercept of 13 metres at 0.38% copper and 38 grams per tonne silver from 291 metres, confirming continuity along the contact and increasing confidence that mineralisation extends along the fold geometry.
Managing director and chief executive officer Victor Rajasooriar said the latest results were highly encouraging, particularly in demonstrating continuity at both Qembo and Steenbok.
He said even holes that failed to return economic assays had contributed to a better understanding of structure and stratigraphy, allowing the company to refine its geological model and follow-up strategy.
Rajasooriar added that with copper and silver prices at recent highs, Noronex believes the Powerline Project sits within one of the most under-explored segments of the Kalahari Copper Belt spanning Namibia and Botswana.
The Powerline Project is located within EPLs 9551 and 9552 in eastern Namibia and forms part of Noronex’s broader copper exploration portfolio in the region.
The project targets domal structures and fold closures along the northern margin of the Kalahari Copper Belt, a globally recognised copper province that hosts several significant deposits in neighbouring Botswana.
Exploration at Powerline commenced in September 2025 as part of a South32-funded earn-in, designed to test multiple high-priority domes identified through modern geophysical and structural interpretation.
With first-phase drilling now complete at Steenbok and Qembo North, Noronex said follow-up drilling will focus on step-out holes to test continuity along hinge zones, additional drilling along the northern limb of the Qembo anticline where magnetic lineaments indicate structural flexures, and continued drilling at the Zambinda Dome, where operations are now under way.
Noronex is an ASX-listed copper explorer with advanced projects across the Kalahari Copper Belt in Namibia and Botswana. In Namibia, the company already hosts a JORC 2012 resource of 10 million tonnes at 1.3% copper at its Witvlei and Dordabis projects, underscoring its longer-term ambition to grow a meaningful copper inventory in the country through systematic, partner-funded exploration.
