Golden Deeps Uncovers Rich Copper Zones at Namibia’s Graceland Prospect

Exploration Progress at Graceland

Golden Deeps Ltd (ASX, GED) has announced promising developments at its Graceland Critical Metals Prospect, located in Namibia’s prolific Otavi Mountain Land. Recent trenching and channel sampling have uncovered robust copper mineralisation across two newly identified gossan zones at opposite ends of a 2-kilometre mineralised corridor. These findings build on previous high-grade rockchip results, reinforcing the prospect’s potential as a significant source of critical metals.

The eastern zone, known as Gossan 1 East, exhibits copper mineralisation across 3 to 5 metres, with historic rockchip samples showing exceptional grades including up to 47.3% copper and 7,792 grams per tonne silver. Meanwhile, the newly identified Gossan 1 West Extension reveals copper mineralisation over 3 to 6 metres along a 100-metre strike length, remaining open for further expansion.

Strategic Importance of Critical Metals

Golden Deeps’ exploration targets a suite of metals critical to modern technologies and renewable energy systems. The prospect hosts copper, silver, zinc, lead, germanium, and antimony, all recently designated as critical minerals by the US Geological Survey. This classification underscores the strategic importance of the Graceland metals, especially given supply constraints highlighted by recent export bans from China on germanium and related elements.

Germanium, in particular, is a vital semiconductor material used in transistors and photovoltaic cells, making its availability crucial for the technology sector. The Otavi Mountain Land region is one of the few global sources where germanium is produced as a primary product, positioning Golden Deeps’ project as a potentially significant supplier on the world stage.

Upcoming Geophysical Survey and Drilling Plans

To complement the sampling results, Golden Deeps is set to commence a detailed Induced Polarisation (IP) and resistivity survey within weeks. This geophysical program, conducted by Terratec, will cover the entire 2km by 1km mineralised corridor, aiming to detect sulphide bodies from surface down to 300 metres depth. The survey will initially focus on the high-grade gossan zones before expanding to the broader corridor.

Data from the IP survey will be integrated with channel and rockchip sampling results to build a comprehensive 3D geological model. This model will guide targeted drilling campaigns designed to test for high-grade sulphide deposits analogous to the nearby Tsumeb mine, a world-class deposit that historically produced substantial quantities of copper, lead, zinc, silver, and germanium.

Broader Project Context and Next Steps

Graceland forms part of Golden Deeps’ Central Otavi Project, which includes multiple tenements covering over 440 square kilometres in Namibia’s renowned Otavi Mountain Land metallogenic belt. The company holds an 80% interest in the project through its subsidiaries and is advancing several critical metals prospects with established mineral resources.

Golden Deeps is continuing its aggressive exploration program with further soil and rockchip sampling planned to extend known mineralised trends. The company has secured landholder access agreements and logistical support to facilitate rapid progression from geophysical surveys to drilling.

CEO Jon Dugdale highlighted the significance of the discoveries and the strategic timing of the US Critical Minerals listing, emphasizing the potential for Graceland to contribute to the global supply of high-demand metals essential for clean energy and advanced technologies.
