Prospect finds new high-grade copper zone beyond Nyungu Central
Prospect Resources has identified a new eastern copper zone outside the existing Mineral Resource at Nyungu Central, with two thick intercepts grading up to 0.91% copper. The discovery has prompted a reallocation of drilling as the company works towards resource updates and a Mumbezhi Scoping Study in Q1 2027.
- 24m at 0.78% copper and 20m at 0.91% copper from extensional hole NCDD052
- New mineralisation sits outside the current Nyungu Central Mineral Resource
- 45 Phase 3 diamond holes completed for 14,128 metres
- Further assays remain pending from infill and extensional drilling
- Mumbezhi Scoping Study remains targeted for Q1 2027

Eastern Flank Drilling Opens New Copper Zone
Prospect Resources Limited (ASX:PSC, FRA:5E8) has found two substantial copper intersections beyond the current Mineral Resource at Nyungu Central, adding a new growth target to its 90%-owned Mumbezhi Copper Project in north-west Zambia. Extensional hole NCDD052 returned 24 metres at 0.78% copper from 276 metres and a further 20 metres at 0.91% copper from 375 metres.
The intercepts were not isolated narrow hits. Prospect said the mineralisation appears to envelop a thick amphibolite unit in a geometry resembling the southeastern lobe discovered earlier in the Nyungu Central system, about 450 metres away. The company has since reallocated extensional drilling metres to the eastern flank, where mineralisation remains open in multiple directions. The latest result builds on the October Nyungu extensions, which had already extended copper mineralisation beyond the existing resource.
Infill Results Add Weight to Nyungu Central Resource Work
NCDD052 also produced a shallower 32.8-metre intersection at 0.54% copper from 28 metres. Other infill holes returned 37 metres at 0.52% copper from 228 metres in NCDD042, 9.2 metres at 0.81% copper from 467 metres in NCDD044, 38.7 metres at 0.64% copper from 127 metres in NCDD046 and 30 metres at 0.53% copper from 90 metres in NCDD043.
Those results are intended to refine the geological interpretation and support future Mineral Resource updates rather than represent a revised resource today. The reported widths are downhole lengths, not confirmed true widths, and the new eastern mineralisation has not yet been incorporated into a JORC resource estimate or an economic study. NCDD047, drilled towards western extensions, delivered narrower intersections of 4.4 metres and 1.9 metres at 0.38% copper.
Pending Assays and Q1 2027 Scoping Study
Prospect has completed 45 Phase 3 diamond holes for 14,128 metres at Nyungu Central, with further infill and extensional assays still outstanding. Four diamond rigs are operating across the project, with two at Nyungu Central and two assigned to regional exploration at Kamafamba and Chipimpa.
The immediate test is whether follow-up drilling confirms the eastern zone's continuity and scale. That evidence will feed into planned Mineral Resource updates for Nyungu Central and Kabikupa ahead of the Mumbezhi Scoping Study, which Prospect says remains on track for release in Q1 2027. Until those updates arrive, the high-grade intersections improve the geological picture but do not yet establish additional mineable tonnes.

Bottom Line?
The eastern zone could strengthen Mumbezhi's resource-growth case, but its significance depends on pending assays, true widths and eventual conversion into a coherent Mineral Resource before the Q1 2027 study.
Questions in the middle?
- Will follow-up drilling confirm that the eastern zone has the continuity and scale implied by NCDD052?
- How much of the newly identified mineralisation can be converted into Indicated or Inferred Resources?
- Will the expanded Nyungu Central footprint materially change the Mumbezhi Scoping Study's development assumptions?
