Golden Deeps has identified three significant sulphide targets at its Graceland prospect in Namibia, with maiden drilling revealing exceptional grades of copper, silver, zinc, germanium, and antimony. These findings bolster the company’s ambition to replicate the world-class Tsumeb deposit nearby.
- Three large IP sulphide anomalies defined over an 800m plunging corridor
- Maiden diamond drilling returns up to 34.8% copper and 388 g/t silver
- High-grade mineralisation extends below surface and remains open in all directions
- Targets analogous to the prolific Tsumeb copper-silver-zinc-germanium deposit
- Plans underway for deeper drilling post-Namibian wet season
Exploration Breakthrough at Graceland
Golden Deeps Ltd (ASX: GED) has delivered a compelling update from its Graceland Critical Metals Prospect in Namibia’s Otavi Mountain Land, a region renowned for its polymetallic deposits. The company’s final 3-D modelling of an Induced Polarisation (IP) and Resistivity survey has delineated three major sulphide targets, which bear striking resemblance to the world-class Tsumeb deposit located just 30 kilometres to the north.
The significance of these IP anomalies lies in their scale and grade. Spanning over 800 metres along an easterly-plunging corridor, these targets coincide with zones of low resistivity and high chargeability, hallmarks of sulphide mineralisation. Notably, the largest anomaly extends beyond the survey boundary, remaining open and ripe for further exploration.
Exceptional Maiden Drilling Results
These results validate earlier channel sampling and confirm that the mineralisation extends well below the gossanous surface expression into fresh bedrock. The mineralised zones are steeply dipping and remain open at depth and along strike, suggesting significant potential for resource expansion.
Strategic Implications and Next Steps
Golden Deeps’ CEO Jon Dugdale emphasised the confidence these findings bring to the company’s exploration strategy. The analogy to the Tsumeb deposit, a prolific producer of copper, silver, zinc, lead, germanium, and other critical metals, underscores the potential scale and value of the Graceland discovery.
Looking ahead, the company plans to continue shallow diamond drilling to further delineate the sulphide mineralisation across the gossan zones. More substantial drilling campaigns targeting the deeper IP anomalies are scheduled to commence after the Namibian wet season, with the aim of testing these high-priority sulphide targets at depth.
Golden Deeps’ broader Otavi Mountain Land portfolio includes several advanced base and critical metals projects, positioning the company well within a globally significant mining district. The integration of geochemical, geophysical, and drilling data is expected to refine targeting and accelerate the path towards resource definition.
Bottom Line?
Golden Deeps’ Graceland results mark a pivotal step towards unlocking a potential Tsumeb-scale critical metals deposit, with deeper drilling poised to reveal the full extent of this high-grade mineralisation.
Questions in the middle?
- How extensive and continuous is the mineralisation at depth beyond current drilling?
- What metallurgical characteristics and recoveries can be expected from these complex sulphide ores?
- How will Golden Deeps prioritise and fund the upcoming deeper drilling campaigns?
