Prospect Resources (ASX:PSC) announced a breakthrough at its Mumbezhi Copper Project in north-west Zambia, confirming a substantial near-surface copper sulphide system at the West Mwombezhi prospect.
Following the receipt of final assay results from its Phase 2 diamond drilling program, the company has defined continuous mineralisation extending over more than one kilometre of strike length.
The system remains open to both the west and south, suggesting considerable room for further expansion.
The drilling campaign yielded several high-priority intersections, headlined by hole MWDD004, which returned 8.9m @ 0.78% Cu from 54.6m, including a higher-grade core of 7.0m @ 0.93% Cu.
Other results include 6.7m @ 0.57% Cu (MWDD009) and 5.0m @ 0.47% Cu (MWDD002).
The results are bolstered by extensive soil sampling, which has identified strong copper anomalism stretching another kilometre south of the current drill footprint.
Managing Director and CEO, Sam Hosack, expressed confidence in the project’s "district-scale" potential, noting that these outcomes will be integrated into a maiden mineral resource estimate for West Mwombezhi, scheduled for completion in Q2 2026.
As Prospect continues its exploration activities, the company is also awaiting additional assays to evaluate gold potential within previous copper intercepts.
At the time of reporting, Prospect Resources' share price was $0.34.
