Graceland Mineralised Corridor Grows 500m; Rockchips Hit Up to 42% Copper, 154 g/t Silver

Extension of a Promising Mineralised Corridor

Golden Deeps Ltd (ASX, GED) has announced a significant extension of its Graceland prospect in Namibia’s Otavi Mountain Land, pushing the known mineralised corridor northeast by 500 metres to a total strike length exceeding 2.5 kilometres. This expansion is supported by new soil and rockchip sampling results that reveal high-grade polymetallic mineralisation including copper, silver, zinc, lead, germanium, and antimony.

The standout rockchip samples include remarkable grades such as 42% copper and 154 grams per tonne silver, reinforcing the prospect’s potential to host substantial high-grade deposits. These results build on previous exceptional findings from the Gossan 1 East zone, which yielded up to 7,792 g/t silver, 47.3% copper, and 224 g/t germanium.

Advanced Geophysical Survey to Define Targets

In parallel with surface sampling, Golden Deeps has commenced an extensive Induced Polarisation (IP) and resistivity survey designed to detect both near-surface sulphide bodies and deeper ‘Tsumeb-style’ polymetallic sulphide targets down to 300 metres. The Tsumeb mine, located just 20 kilometres north of Graceland, is a world-class deposit known for its extraordinary polymetallic mineralogy and high grades, making it a compelling analogue for exploration.

The IP survey, initially focused on the priority Gossan 1 and Gossan 1 East zones, will cover the entire mineralised corridor, including the newly extended northeast section. The integration of IP anomalies with detailed 3D aerial satellite imagery and comprehensive soil and rockchip data aims to generate precise drilling targets for the next phase of exploration.

Strategic Importance of Critical Metals

Golden Deeps’ exploration targets include critical metals such as copper, silver, germanium, and antimony, all of which are increasingly vital for renewable energy technologies, electronics, and strategic supply chains. The recent addition of copper, silver, and lead to the US Critical Minerals list underscores the growing demand and geopolitical importance of these metals. Notably, China’s export restrictions on germanium, gallium, and antimony to the US have heightened the urgency for alternative sources.

The company’s extensive tenement holdings in the Otavi Mountain Land encompass several advanced base and critical metals projects, with Graceland representing a key focus area due to its Tsumeb-style polymetallic potential.

Next Steps and Drilling Plans

Golden Deeps is awaiting results from pending channel sampling across the highly mineralised Gossan 1 East and West Extension zones. These results, combined with the IP survey data and 3D modelling, will inform the selection of priority drilling targets. The company has identified suitable drilling rigs capable of accessing the challenging terrain at Graceland and plans to commence drilling once all data is integrated and targets are finalised.

With landholder access agreements and infrastructure in place, Golden Deeps is positioned to advance rapidly into the drilling phase, aiming to confirm and expand the high-grade polymetallic mineralisation at depth.
