Oscillate PLC has reported significant copper mineralisation at its Kaoko Basin Project in Namibia following the latest drilling results from the Omatapati prospect.
The company confirmed the findings ahead of its planned acquisition of Kalahari Copper Limited (KCL), which carried out the drilling on Exclusive Prospecting Licence (EPL) 7081.
The standout result came from drill hole OPR013, which returned 27 metres of mineralisation averaging 0.59% copper and 34.3 parts per million (ppm) silver from a depth of 61 metres.
The interval included higher-grade sections of 3 metres at 1.52% copper and 59 ppm silver, 3 metres at 1.07% copper and 64 ppm silver, and 5 metres at 0.42% copper and 50 ppm silver. Other intersections included 2 metres at 0.59% copper from hole OPR012 and 2 metres at 0.38% copper in OPR014.
Oscillate CEO Robin Birchall said the results strengthen understanding of the project’s mineral system and confirm the potential for extension at depth.
“I am delighted with these drilling results as they will help us build on our existing knowledge and understanding of the mineralisation system in this region. We have seen that the sedimentary units containing the primary mineralisation can be mapped on a regional scale, and with this drilling we have shown that mineralisation also extends at depth,” he said.
The seven-hole reverse circulation programme was completed in August 2025 for a total of 736 metres. It follows initial intersections reported in 2024 and further reinforces confidence in the copper potential at Omatapati.
The Kaoko Basin hosts stratiform sediment-hosted copper mineralisation similar to deposits in the Central African Copperbelt.
At Omatapati, mineralisation is found within the Neoproterozoic Devede Formation of the Ombombo Subgroup, above traditional Lower Omao and Omivera targets.
Copper occurs in carbonate, oxide and sulphide form, with grades typically between 0.5% and 1%, increasing where faulting and alteration have concentrated mineralisation.
Birchall said the company will now focus on advancing its exploration plans and defining maiden mineral resources at priority targets.
“Further surface exploration and drilling along strike from these discovery holes will assist in delineating maiden mineral resources at the highest priority targets. We are excited to develop our work programme at Omatapati as it shows significant potential. We will update the market shortly on our near-term exploration plans and objectives,” he said.
Oscillate confirmed that QAQC standards were met during the campaign, with all certified reference materials returning results within two standard deviations of expected values. The company will take over all future exploration work at the site once the acquisition of KCL is finalised in early 2026.
