The Graceland Prospect in Namibia has garnered significant attention due to its exceptional channel sampling results. Golden Deeps Ltd, an Australian mining company, recently announced findings that reveal substantial concentrations of copper, silver, and other essential metals within the Otavi Mountain Land Critical Metals District. These results not only validate the prospect’s potential but also suggest a geochemical signature similar to that of the renowned Tsumeb mine, located nearby.
As exploration evolves, the focus has shifted to the Gossan 1 East outcrop, which has yielded remarkable grades in recent channel sampling. Concentrations reaching 42.7% copper and over 1,300 g/t silver present a strong case for further exploration and drilling activities in the region.

Remarkable channel sampling results
The latest channel sampling results from the Gossan 1 East outcrop showcase some of the highest grades of copper and silver recorded in the area. Notably, Channel A6CL009 reported an impressive 3.5 meters of mineralization containing 12.6% copper and 79 g/t silver, with particularly high-grade intersections within this interval. A portion of this sample revealed 27.6% copper and 140 g/t silver, highlighting the potential for discovering rich ore bodies in the vicinity.
Highlights of channel sampling
Additional sampling from Gossan 1 East has produced outstanding results. For example, Channel A6CL008 returned 9.2% copper and 135 g/t silver over a length of 3.0 meters, with elevated grades recorded within specific intervals. Another channel, A6C1_007, exhibited 16.2% copper and 442 g/t silver over 2.0 meters. These findings not only reinforce the case for Graceland’s potential but also align with the geochemical profile of the Tsumeb mine.
Geological context and ongoing exploration
The geological environment of Graceland is particularly intriguing, as it shares characteristics with the Tsumeb mine, known for its substantial production of copper, lead, zinc, and silver. The Tsumeb mine features a structurally controlled sulfide ore-body, formed from hydrothermal fluids infiltrating fault structures into brecciated carbonate rocks. This historical context implies that Graceland may also exhibit similar structural controls, indicating the likelihood of rich mineralization.
To investigate these promising results further, an Induced Polarisation (IP)-Resistivity Survey is currently being conducted across the key gossan zones. This survey aims to pinpoint potential high-grade drilling targets that resemble the deposits found at Tsumeb, both at shallow and deeper levels.
Plans for future drilling
In light of these exciting results, Golden Deeps is actively seeking drilling contractors to initiate an initial drilling program designed to test beneath the identified gossans and IP targets. These efforts are essential for confirming the extent of mineralization and assessing the feasibility of establishing a mine at Graceland.
Jon Dugdale, CEO of Golden Deeps, emphasized the importance of these findings, stating that the high-grade results from Gossan 1 East illustrate the potential for extensive mineralization. He noted the geological similarities to the Tsumeb mine and expressed enthusiasm for advancing exploration initiatives.
As exploration progresses, the company remains optimistic about the prospect of uncovering substantial deposits of copper, silver, and other critical metals, making Graceland a site of considerable interest in the coming months.
