Prospect Hits 31.9% Copper Concentrate at Kabikupa in Zambia

Prospect Resources (ASX: PSC) reported copper concentrate grades of 31.9% and 25% from metallurgical testwork on transition and low-grade fresh mineralisation at the Kabikupa deposit within the Mumbezhi Copper Project in northwest Zambia.

The testing, conducted by Core Metallurgy in Brisbane, used composite samples from a dedicated drill hole. The transition zone material yielded 31.9% copper at a 94.7% recovery. The low-grade fresh zone produced 25% copper at 94.3% recovery.

Both results came from a simple flowsheet with a single cleaning stage. That processing path matches the one used on other Mumbezhi materials, including the Nyungu Central and Kabikupa high-grade zones. A straightforward flowsheet keeps capital and operating costs lower, which matters for a project at the scoping stage.

CEO Sam Hosack said the results “reinforce our conviction in the strong economic potential of the Mumbezhi project.” He noted the deposits continue to show they work with an established, conventional processing flowsheet, delivering attractive recoveries and good concentrate quality. The simple processing, combined with a coarse primary grind size and potential gold and cobalt by-product revenue, creates a strong technical and financial lever for Mumbezhi.

Hosack said the datasets will underpin a project Scoping Study scheduled for the fourth quarter of 2026 or the first quarter of 2027.

Concurrent Phase 3 drilling is underway at the site. It targets further resource growth within the Nyungu Hub and regional targets. Initial assays are due in coming weeks.
