Uranium exploration company Madison Metals has recently unveiled promising assay results, indicating an average uranium oxide (U3O8), also known as yellowcake, content of 2.78% at Trench 6 in the Erongo region.
This discovery follows closely on the heels of the company’s previous announcement regarding the uncovering of high-grade uranium mineralisation at their Khan site, including a surface sample displaying 8.47% uranium ore concentrate (U3O8).
According to the company’s report, the results span a distance of over 600 metres from Trench 1 (KM5TR001) northeast to Trench 6, with an average grade of 0.47% U3O8 across the six trenches.
The most notable findings were from Trenches 4 and 5 (KM5TR004 and KM5TR005), boasting 9.0 metres over 0.25% U3O8 and 0.39% U3O8, respectively.
“We are highly encouraged by this discovery and the significant high-grade uranium assays from this area,” stated Madison Metals’ Executive Chairman and CEO, Duane Parnham.
The company has identified extremely high-grade uranium mineralised alaskites at the surface, spanning over 800 metres.
Parnham expressed confidence that a maiden drilling program will uncover similar mineralisation at depth, further solidifying the potential of the area.
Throughout the prospecting and trench sampling, numerous occurrences of beta-uranophane (yellow staining) were observed.
Beta-uranophane is typically found in uranium deposits near the Welwitschia lineament and serves as evidence of alteration processes that have mobilised and deposited secondary uranium.
Madison Metals’ structural interpretation of the geological data suggests proximity to a dilation zone where mineralised alaskites were preferentially emplaced in an en-echelon pattern, as demonstrated in the 300-metre wide cross-section.
If these mineralised alaskites converge at depth, it could signify significant mineralisation beneath the surface.
The elevation across the NE-SW cross-section drops by approximately 30 metres southwestward, while the entire extent of the 800-metre strike of the potentially mineralised zone sits approximately 50 metres above ground level, making it readily accessible for exploration activities.
