Prospect Resources Unveils New Copper Extensions at Mumbezhi
Prospect Resources reports promising Phase 2 drilling results at its Mumbezhi Copper Project, revealing new strike extensions at the Nyungu Central deposit and advancing exploration across the licence.
- Phase 2 diamond drilling confirms expanded copper mineralisation at Nyungu Central
- Significant copper intervals include 60.5m at 0.53% Cu and 18m at 0.59% Cu
- Airborne electromagnetic surveys and soil sampling progressing on schedule
- Regional aircore drilling to target new geochemical anomalies starting August
- Metallurgical testwork shows strong copper recovery from fresh sulphide zones
Exploration Momentum Builds at Mumbezhi
Prospect Resources Limited (ASX – PSC) has delivered a robust update on its Phase 2 exploration program at the Mumbezhi Copper Project in north-west Zambia. The company’s ongoing diamond drilling campaign at the flagship Nyungu Central deposit has confirmed new strike extensions, reinforcing the presence of a large-scale copper system. Since the last update, six additional drill holes totaling 1,721 metres have been completed, with assays from two holes released and encouraging results from the rest pending.
Significant Copper Intercepts Validate Growth Potential
Among the highlights, drill hole NCDD010 intersected 60.5 metres grading 0.53% copper starting from 296 metres depth, including a higher-grade 33 metres at 0.71% copper. Another hole, NCDD009, returned 18 metres at 0.59% copper, with a notable 6.3 metres at 1.11% copper. These intervals extend mineralisation both up-plunge and down-plunge, spanning oxide, transitional, and sulphide zones. The results support the company’s geological model and suggest the deposit’s mineralised horizons are thickening, a positive sign for resource expansion.
Integrated Geophysical and Geochemical Programs Advance
Complementing drilling, Prospect has completed airborne electromagnetic surveys over the Nyungu and Kabikupa corridors, with interpretation underway. These surveys aim to identify conductive zones associated with copper mineralisation. Additionally, a licence-wide soil geochemical sampling program is progressing, with a third of planned samples collected since mid-July. These datasets will guide upcoming aircore drilling, scheduled to commence in early August, targeting cohesive geochemical anomalies at West Mwombezhi and Nyungu North.
Strategic Partnership and Metallurgical Progress
Prospect’s collaboration with First Quantum Minerals, a major player in the copper sector, provides technical support and strategic insight. Metallurgical testwork on copper mineralisation from Nyungu Central and Kabikupa continues to yield promising flotation results, with copper recoveries between 81% and 96% and concentrate grades of 25-32% copper. These outcomes are critical for assessing the project’s economic viability and advancing towards feasibility studies.
Outlook for Mumbezhi’s Copper Future
With a maiden mineral resource estimate of 107.2 million tonnes at 0.5% copper already established, the ongoing exploration and drilling efforts aim to expand this base and unlock further value. The Mumbezhi Project’s location within the prolific Central African Copperbelt and its alignment with global electrification trends position it as a compelling copper exploration story. Investors will be watching closely as assay results from pending drill holes and geophysical interpretations emerge in the coming months.
Bottom Line?
Prospect Resources is steadily advancing Mumbezhi towards a significant copper resource, with upcoming assay results and geophysical data set to shape the next phase of exploration.
Questions in the middle?
- How will pending assay results from Kabikupa influence the overall resource potential?
- What impact will the airborne electromagnetic survey interpretations have on targeting new mineralised zones?
- How might metallurgical testwork outcomes affect the project’s development timeline and economics?
