Prospect Resources Identifies Major Copper Target at West Mwombezhi, Zambia, as Diamond Drilling Commences
Prospect Resources Limited (ASX:PSC) has announced that its recent aircore drilling program at the West Mwombezhi prospect in north-west Zambia has returned highly anomalous copper mineralisation at shallow depths, covering over 1 km of strike.
The results highlight a new, high-potential target within the company’s Mumbezhi Copper Project, where Prospect holds an 85% interest.
The newly identified target aligns with a well-defined 1.5 km north-northeast trending copper anomaly, originally detected through regional termite mound geochemical sampling.
Encouraging historical geophysical and geochemical results further support the prospectivity of this area.
In response, diamond drilling has now commenced to test the continuity of the subsurface copper mineralisation.
Prospect’s Managing Director and CEO, Sam Hosack, commented:
“We are very pleased with the results of the recent aircore drilling at West Mwombezhi. The exploration work undertaken has strengthened our confidence in the potential of this target, and it is an exciting milestone to have a diamond drill rig actively testing this large-scale regional target.
With multiple rigs active across the corridor and assay results pending, we anticipate a busy quarter as we advance Nyungu South, Nyungu North, and West Mwombezhi in parallel.”
Aircore Drilling Highlights
During the first half of 2025, Prospect completed extensive termite hill geochemical sampling over the West Mwombezhi area, identifying two prominent north-northeast trending anomalies.
These anomalies were subsequently targeted with 69 shallow aircore drill holes totaling 1,387 meters, averaging 20 meters in depth, on a 200m x 50m grid.
The aircore drilling confirmed highly anomalous near-surface copper mineralisation (>0.05% Cu) across 1 km of strike. Some of the best vertical downhole intersections included:
22m @ 0.17% Cu from 8m (MWAC008)
23m @ 0.09% Cu from 0m (MWAC016)
17m @ 0.10% Cu from 8m (MWAC015)
7m @ 0.21% Cu from 17m (MWAC052)
8m @ 0.14% Cu from 6m (MWAC023)
These results support the prospectivity of the newly defined eastern target zone.
Phase 2 Diamond Drilling Program
Phase 2 diamond drilling at Mumbezhi is progressing well, both on schedule and within budget. Approximately 77% of the planned Phase 2 diamond drilling has been completed.
Resource definition drilling at the Nyungu Central and Kabikupa deposits is complete, with regional exploration now the primary focus.
Ongoing drilling activities are targeting high-priority areas, including West Mwombezhi, Nyungu South, and Nyungu North.
Assay results from a number of Phase 2 diamond drill holes are still pending, primarily due to extended turnaround times at local laboratories, reflecting the seasonal peak in exploration activity across northwestern Zambia.
Next Steps
Prospect Resources plans the following in the coming months:
Completion of airborne electromagnetic (AEM) survey interpretation, with results expected in September.
Finalisation of licence-wide soil geochemical sampling, with full results due in October.
Compilation of all drillhole analytical data to update the existing JORC-reportable Indicated and Inferred copper resources for Nyungu Central and Kabikupa in Q4 2025.
Commencement of regional ground-based IP surveys at Mumbezhi to test additional termite mound-defined geochemical targets, including Kamafamba, Luamvunda, and Shikezi.
Extension of the aircore program to surface copper anomalies near Nyungu North, Nyungu South, and Chalamba.
Prospect Resources continues to systematically advance its exploration efforts across the Mumbezhi region, aiming to expand its high-quality copper resource base in Zambia’s prolific Copperbelt.
