Golden Deeps Launches Deeper Drilling at Graceland Copper-Silver-Zinc-Germanium Targets
Golden Deeps has kicked off a deeper diamond drilling program at its Graceland discovery in Namibia, aiming to test high-grade copper-silver-zinc-lead-germanium sulphide zones analogous to the world-class Tsumeb deposit. Recent shallow drilling confirmed continuity of exceptional grades, underpinning the exploration push.
- Deeper drilling targets three priority IP sulphide zones
- Assays up to 9.2% copper and 118 g/t germanium confirm high-grade continuity
- Initial 10 holes focus on down-plunge extensions of Gossan 1 corridor
- Graceland lies in Namibia’s Otavi Mountain Land Critical Metals Belt
- Exploration supported by extensive geophysical and geochemical data
Deeper Diamond Drilling Targets High-Grade Sulphides
Golden Deeps Ltd (ASX:GED) has commenced a deeper diamond drilling campaign at its Graceland discovery in Namibia’s prolific Otavi Mountain Land Critical Metals Belt, aiming to test three priority copper-silver-zinc-lead-germanium sulphide targets identified by induced polarisation (IP) surveys. The program focuses on down-plunge extensions of the high-grade Gossan 1 and Gossan 1 East zones, with a planned initial 10 diamond holes probing sulphide mineralisation down to depths exceeding 200 metres.
The targets share a striking geological and geochemical resemblance to the world-class Tsumeb deposit, located just 30 kilometres north of Graceland. Tsumeb is renowned for its rich polymetallic ore, historically producing 27 million tonnes at grades of 4.3% copper, 10% lead, 3.5% zinc, 95 g/t silver, and 50 g/t germanium. Golden Deeps is pursuing a similar steeply dipping carbonate-hosted sulphide system, with multiple IP chargeability anomalies extending over an 800-metre strike length and remaining open at depth and to the east.
Shallow Drilling Confirms High-Grade Continuity
These results continue to build on Golden Deeps’ earlier surface channel sampling, which recorded exceptional grades such as 3 metres at 11.2% copper and 294 g/t silver, and 0.5 metres hitting 31.7% copper and 961 g/t silver. The company’s CEO Jon Dugdale emphasised that the consistent and spectacular results from previous exploration provide confidence that the IP targets represent significant copper-silver-zinc-lead-germanium sulphide zones.
Strategic Location Within a World-Class Metallogenic Belt
Graceland sits within Golden Deeps’ extensive 440 square kilometre tenement package in the Otavi Mountain Land, a district famed for its high-grade polymetallic deposits. The region hosts major mines such as Tsumeb and Kombat, with the latter historically producing 12.5 million tonnes at 2.6% copper and 1.6% lead. Golden Deeps’ portfolio also includes advanced base and critical metals projects like Abenab, Nosib, Khusib Springs, Border, Driehoek, and Kaskara, all within the same metallogenic belt.
The company’s exploration approach integrates geological mapping, rockchip and soil geochemistry, channel sampling, and detailed IP-resistivity geophysical surveys. The recent IP survey over Graceland delineated three significant chargeability anomalies interpreted as sulphide targets analogous to Tsumeb’s mineralisation style. The largest of these, the Gossan 1 Far East target, lacks surface expression and remains open along strike and at depth, representing a compelling blind target for the ongoing drilling program.
Next Steps in Exploration and Development
Golden Deeps plans a staged drilling program, with the initial phase testing down-plunge extensions of the Gossan 1 corridor, followed by deeper drilling of the eastern IP targets. The company anticipates several months of drilling, with assay results to be released progressively. Metallurgical test work is also planned to optimise recovery of critical metals, including germanium and antimony, which add strategic value given their use in semiconductor and specialty applications.
This drilling campaign represents a critical step in advancing Graceland from a high-potential exploration prospect toward delineation of a meaningful resource. The combination of high-grade assay results, robust geophysical anomalies, and geological analogy to Tsumeb positions Golden Deeps well within the competitive landscape of critical metals exploration in Namibia.
Bottom Line?
Golden Deeps’ deeper drilling at Graceland could unlock a significant polymetallic sulphide system, but results remain pending and will be crucial to validate the scale and economic potential of these high-grade targets.
Questions in the middle?
- Will the deeper drilling confirm the continuity and scale of the high-grade sulphide zones at depth?
- How will metallurgical recoveries of germanium and antimony influence project economics?
- What impact will ongoing assay results have on Golden Deeps’ resource estimates and development plans?
