Copper Potential Grows at West Mwombezhi as Mineralisation Remains Open and Expanding

Emerging Copper Opportunity at West Mwombezhi

Prospect Resources Limited (ASX:PSC) has released the final assay results from its Phase 2 diamond drilling programme at the West Mwombezhi prospect, part of the Mumbezhi Copper Project in north-west Zambia. The results reveal a continuous near-surface copper sulphide mineralisation extending over more than one kilometre of strike length, with the system remaining open to the west and south. This discovery adds a compelling new chapter to Prospect’s growing footprint in the prolific Central African Copperbelt.

Significant Drill Intersections Highlight Potential

The drilling programme, comprising twelve holes totalling over 2,200 metres, has delineated two distinct zones of copper mineralisation. Noteworthy intersections include 8.9 metres at 0.78% copper, including 7 metres at 0.93% copper from 54.6 metres depth, and 6.7 metres at 0.57% copper, including 4.2 metres at 0.75% copper. These grades, while moderate, are significant given the near-surface nature of the mineralisation, which could translate into more cost-effective mining scenarios.

Geological Context and Exploration Outlook

The copper mineralisation is hosted within a biotite-rich, kyanite-bearing schist horizon, structurally controlled and dipping shallowly to the west. The presence of chalcopyrite as the dominant copper sulphide, along with associated minerals such as sphalerite and pyrrhotite, aligns with the typical geology of the Zambian Copperbelt. Soil sampling has further identified strong copper anomalies extending over 1km south of the drilled area, suggesting the mineralised system could be more extensive than currently defined.

Towards a Maiden Mineral Resource Estimate

Prospect Resources is on track to deliver a maiden Mineral Resource Estimate (MRE) for West Mwombezhi in the second quarter of 2026. This will complement the recently updated resource estimates for the nearby Nyungu Central and Kabikupa deposits, reinforcing the district-scale potential of the Mumbezhi Project. The company is also conducting targeted re-assaying to better understand the gold potential associated with the copper mineralisation, an aspect that could add further value.

Strategic Implications and Next Steps

With Phase 3 drilling planned to commence in Q2 2026, Prospect Resources is poised to expand its exploration footprint across multiple targets within the Mumbezhi licences. The ongoing work aims to unlock additional copper, gold, and cobalt resources, potentially feeding into a future centralised mining and processing operation. The proximity to major mines operated by First Quantum Minerals adds strategic value, offering infrastructure and market access advantages.
