Key Highlights

Rock chip sampling at South Ridge returned up to 680 grams per tonne silver, 6.67 per cent zinc and 2.07 per cent copper.
The high-grade zone covers a 1-kilometre strike corridor within a broader 400-metre-wide anomalous zone.
Three diamond holes at Graceland intersected disseminated copper and zinc mineralisation below Gossan 1.
Channel sampling and shallow diamond drilling are planned at South Ridge following the rock chip results.

Golden Deeps Ltd (ASX:GED) has reported new high-grade copper, silver, zinc and lead rock chip results from its South Ridge prospect in the Otavi Mountain Land of north-eastern Namibia, along with an update on diamond drilling at the Graceland prospect. The announcement, dated 10 November 2026, describes South Ridge as the company's second prospect of the Tsumeb type, after Graceland, and points to mineralisation across a broad corridor that has not yet been drill tested.

South Ridge Rock Chip Results

The new results come from 132 rock chip samples collected within a corridor measuring about one kilometre along strike and 400 metres wide, which was defined by highly anomalous copper, zinc and silver soil sampling. The highest-grade sample, SRGS0067, returned 680 grams per tonne silver, 6.67 per cent zinc and 2.07 per cent copper. Sample SRGS0036 returned 279 grams per tonne silver and 3.3 per cent copper, while sample SRGS0083 returned 183 grams per tonne silver, 7.03 per cent zinc and 2.38 per cent copper.

The company links the mineralisation to hydrothermal brecciation and silicification of the host dolomite. Copper minerals include malachite and azurite. Rock chip samples are selectively collected, so the grades indicate the presence of mineralisation at the sampled points rather than the average grade of the corridor. The company acknowledges that wider sampling will be required to understand the continuity of the zones.

Graceland Diamond Drilling

At Graceland, three diamond holes have been drilled below the Gossan 1 zone. All three intersected intervals of disseminated copper and zinc mineralisation within the target area of an induced polarisation geophysical anomaly. Drilling has since moved to test under Gossan 1 East, where a higher-amplitude geophysical anomaly is offset from the copper gossan. The third and highest anomaly, Gossan 1 Far East, has no surface expression and is open to the east and at depth.

The company notes that the gossan has previously produced high-grade diamond drilling results of up to 34.8 per cent copper and rock chip grades of up to 37.6 per cent copper. Historic surface grades of this kind are not necessarily representative of the mineralisation that drilling will encounter, and the company has not reported an average grade or width for the Graceland drilling.

Next Steps and Program Plans

At South Ridge, the company plans diamond saw channel sampling across the most highly mineralised zones, followed by shallow diamond drilling. The company says the program is intended to test beneath the highest-grade zones. Drilling at Graceland will continue to test the higher-amplitude geophysical anomalies, including the offset Gossan 1 East area and shallow drilling under the Gossan 1 south-west zone, where previous rock chips returned up to 28.3 per cent copper and 30 per cent zinc.

Results from these programs will take time to arrive. Channel sampling and drilling must be assayed and interpreted before the company can assess the size or grade of any mineralised body.

Risks, Context and Limitations

The company's latest announcement focuses on exploration sampling, and the results carry the usual limitations of early-stage work. Rock chip samples are biased toward visibly mineralised material, and geophysical anomalies do not in themselves confirm mineralisation. The company's comparisons with other Tsumeb-type deposits describe a geological model rather than the performance of its own tenure.

The Otavi project tenure and its Namibian operating setting also carry jurisdictional, permitting and funding considerations that the announcement does not address in detail. Future drilling will depend on the company's financing position, which is not discussed in this update.

Final Word

Golden Deeps has added a set of high-grade rock chip results to a corridor it describes as an extensive mineralised system, while drilling at Graceland continues to test the highest geophysical targets. Whether South Ridge develops into a drill-ready prospect will depend on the channel sampling and shallow drilling that follow. The results from that work will show whether the high-grade surface samples are part of a broader and more continuous zone.

FAQs

Q: What were the highest-grade results at South Ridge?

A: Sample SRGS0067 returned 680 grams per tonne silver, 6.67 per cent zinc and 2.07 per cent copper from a hydrothermal breccia.

Q: How large is the South Ridge target area?

A: The rock chip sampling covers a corridor about 1 kilometre along strike and 400 metres wide, defined by anomalous soil results.

Q: What drilling has been done at Graceland?

A: Three diamond holes have been drilled below Gossan 1, intersecting disseminated copper and zinc mineralisation within an induced polarisation anomaly, with testing now moving to adjacent targets.

Q: Are the rock chip grades representative of the whole corridor?

A: Not necessarily. Rock chips are selectively collected from visibly mineralised material, so the grades show the presence of mineralisation at sampled points rather than average grades.
