Golden Deeps says several Namibian drilling contractors have visited the Central Otavi Prospect site to assess access and logistics in the hilly terrain.
The company has engaged international geophysical contractor Terratec to conduct an extensive IP and conductivity survey over the Graceland Prospect, a key target within its recently acquired Central Otavi Project.
Once the Induced Polarisation (IP) survey and channel sampling results are integrated into geological models, drill targets will be finalised.
The program, scheduled to begin within weeks, is designed to detect mineralised sulphide zones both near surface and at depths of up to 300 metres, to identify copper, silver, zinc, lead and germanium-rich deposits.
Initial sampling has already confirmed the potential of Graceland.
At Gossan 1, assays reached 38.3% copper, 35.4% zinc and 1,130g/t silver. G1 East produced extraordinary values of 47.3% copper, 7,792g/t silver and 224g/t germanium.
Gossan 2 yielded up to 29% copper, 32.4% zinc, 3,179g/t silver and 97g/t germanium.
A newly identified western extension, measuring more than 100 meters in length and 20 meters in width, with visible malachite veins, will also be covered by the survey.
Golden Deeps says that the mineralisation at Graceland closely resembles the gossan outcrop that led to the discovery of the legendary Tsumeb Mine, only 20km away.
Like Tsumeb, which ultimately produced 27Mt of ore grading 4.3% copper, 10% lead, 3.5% zinc, 95g/t silver and 50g/t germanium, the Graceland gossans are enriched in polymetallic sulphides.
They may conceal larger, high-grade systems at depth.
Channel samples from the gossan zones are currently being processed at Intertek Laboratories in Namibia and Perth, with results expected within a few weeks.
These results, when combined with the geophysical data, are expected to define the first round of drill targets.
Through its 80% owned subsidiaries Huab Energy and Metalex Mining and Exploration, Golden Deeps holds six Exclusive Prospecting Licences spanning over 440 square kilometres in Namibia’s world-class Otavi Mountain Land.
The company’s portfolio includes both established resources and new discoveries, ranging from high-grade vanadium to polymetallic sulphide deposits enriched with copper, silver, zinc, lead, gallium and germanium.
At the Abenab Project, Golden Deeps has already defined a new high-grade vanadium resource, with lead and zinc credits.
The nearby Nosib deposit has confirmed vanadium, copper, lead, silver and gallium mineralisation, with recent assays revealing exceptionally high gallium values along with anomalous germanium and antimony.
Further metallurgical work is underway to improve recovery before advancing to development studies.
Another cornerstone is the Khusib Springs deposit, historically recognised for its silver and copper, now being reassessed for zinc and lead potential as part of Golden Deeps’ broader critical-metals strategy.
Most recently, the company secured an 80% interest in the Central Otavi Critical Metals Project, a large landholding with multiple prospects and resource targets.
This includes a zinc-lead-silver resource at the Border prospect, advanced Zn-Pb-Ag exploration at Driehoek, and copper-vanadium-polymetallic potential at Kaskara.
Several target areas within Central Otavi show the hallmarks of “Tsumeb-type” deposits—the kind of polymetallic systems that made the Otavi belt world famous for copper, lead, zinc, silver, gallium and germanium production.
