Golden Deeps has reported silver grades of up to 680 grams per tonne from rock-chip sampling at its South Ridge prospect in Namibia’s Otavi Mountain Land, while ongoing diamond drilling at Graceland has intersected copper and zinc mineralisation.
The results were announced on Tuesday, 10 November 2026, following the collection of 132 rock-chip samples across a mineralised corridor measuring approximately one kilometre in length and 400 metres in width.
The highest-grade sample, SRGS0067, returned 680 grams per tonne silver, 6.67% zinc and 2.07% copper.
Another sample, SRGS0036, returned 279 grams per tonne silver and 3.3% copper, while sample SRGS0083 contained 183 grams per tonne silver, 7.03% zinc and 2.38% copper.
Other samples returned 12.57% zinc with 98 grams per tonne silver, and 11.19% zinc with 97 grams per tonne silver and 2.1% lead.
Golden Deeps said the results confirmed extensive copper, silver, zinc and lead mineralisation associated with hydrothermal brecciation and silicification of dolomite rocks.
The mineralised corridor was initially identified through soil sampling that detected elevated concentrations of copper, zinc and silver.
South Ridge lies at the eastern end of the Pavian mineralised trend, which includes the Border inferred mineral resource of 16.2 million tonnes grading 2.12% combined zinc and lead and 4.76 grams per tonne silver.
The company considers South Ridge its second prospective Tsumeb-type mineralisation target after Graceland.
Golden Deeps plans to undertake diamond-saw channel sampling across the strongest mineralised zones before conducting shallow diamond drilling to test whether the mineralisation continues below the surface.
The company is also considering induced-polarisation geophysical surveys to identify deeper exploration targets.
At Graceland, Golden Deeps reported that three diamond drillholes completed beneath the Gossan 1 zone had intersected disseminated copper and zinc mineralisation.
The intersections occurred within an area previously identified through induced-polarisation surveying.
The company said the mineralisation had been identified through geological logging, with laboratory assay results expected within four to six weeks.
Drilling has since moved to Gossan 1 East, where a stronger geophysical anomaly occurs away from the surface copper gossan.
The next target is Gossan 1 Far East, which Golden Deeps described as its strongest induced-polarisation anomaly identified to date.
Unlike the mineralised zones exposed at the surface, Gossan 1 Far East has no surface expression, making drilling necessary to establish whether the geophysical anomaly is associated with mineralisation.
Additional shallow diamond drilling is planned at Gossan 1 Southwest.
Golden Deeps chief executive Jon Dugdale said the latest results had established South Ridge as another prospective exploration target alongside Graceland.
The company intends to use channel-sampling results to determine the most promising drilling locations at South Ridge while continuing to investigate deeper geophysical targets at Graceland.
Although the South Ridge rock-chip samples returned high grades, they represent individual surface samples rather than average grades across the mineralised corridor.
Similarly, the copper and zinc mineralisation identified at Graceland remains subject to laboratory assay results before definitive grades and intersection widths can be reported.
