Cobre Ltd (ASX:CBE) has reported a significant copper discovery at its Ngami Copper Project (NCP) in Botswana, marking a promising milestone in its ongoing exploration of the Kalahari Copper Belt (KCB). This latest finding underscores the region’s potential as a prolific mining frontier and strengthens the company’s position in the global copper market.
The company’s first exploration hole at the NCP revealed a 21-metre-thick zone of chalcocite mineralisation, with notable grades improving as drilling progressed towards the footwall contact. Specifically, the zone displayed disseminated, fracture-hosted, and cleavage-hosted chalcocite, with concentrations escalating from an estimated 0.3% to over 3%. Quartz-carbonate vein-hosted mineralisation was also encountered, with chalcocite grades surging to approximately 5% in specific sections.
These observations, backed by portable X-ray fluorescence (pXRF) analysis, have allowed Cobre to refine its understanding of the geological continuity of the mineralisation. The results indicate significant potential to expand on the current exploration target of 103 to 166 million tonnes, with copper grades ranging between 0.38% and 0.46%.
The drill site, located 7.5 kilometres along the strike of the Comet target, opens up new possibilities for high-grade mineralisation in previously unexplored zones northeast of the existing target. These findings align with airborne gravity gradiometry (AGG) data, providing further vectors for future drilling campaigns.
Adam Wooldridge, Cobre’s Chief Executive Officer, expressed optimism about the results, emphasising the strategic importance of the discovery. “This intersection not only augments our significant exploration target but also highlights the untapped potential of the Ngami Copper Project,” he said. “The spatial correlation with AGG data offers valuable insights for target generation and underscores the broader promise of the Kalahari Copper Belt.”
Cobre is now preparing for infill drilling at the Comet target, aiming to bring a portion of the exploration target into a higher confidence category. Despite the inherent risks of mineral exploration, the company’s shares remain steady, trading at 5.9 cents, reflecting market anticipation of further positive developments.
Botswana’s Kalahari Copper Belt has drawn increasing attention from global mining firms due to its relatively underexplored yet highly prospective geology. As Cobre advances its exploration programme, the potential socio-economic benefits for Botswana are substantial, including job creation and infrastructure development. However, such prospects must be balanced with environmental considerations, particularly in a region home to significant biodiversity.
