What is the scale of the Phase 3 drilling program at Prospect Resources (ASX:PSC)?

Prospect Resources has launched an expanded 26,000-meter drilling campaign at its Mumbezhi Copper Project. The program utilizes a multi-rig strategy consisting of 60 diamond core holes, 30 reverse circulation (RC) holes, and 320 scout aircore holes.

Why is the Nyungu ‘Hub’ a critical focus for Prospect Resources (ASX:PSC)?

The Nyungu ‘Hub’ is a primary growth area where teams are conducting extension drilling adjacent to the shallower southern up-dip areas of the existing Nyungu Central deposit. By targeting the Nyungu West prospect and a geophysical conductor to the northeast, management aims to significantly grow the project's footprint.

What are the current resource estimates for the Mumbezhi Copper Project?

The Mumbezhi Project currently holds an Indicated and Inferred Mineral Resource Estimate (MRE) of 173.8 million tonnes (Mt) grading 0.44% copper. This equates to approximately 0.50% copper equivalent (CuEq).

How is Prospect Resources (ASX:PSC) using technology to improve drilling accuracy?

The company is integrating ground-based geophysical induced polarization (IP) surveys at the Chipimpa and Kamafamba targets. These surveys help map subsurface characteristics, allowing technical teams to refine diamond drill targeting and increase the probability of hitting high-grade mineralization.

Q: What regional targets is Prospect Resources (ASX:PSC) testing beyond the main deposit?

Beyond the central Nyungu area, the company is testing high-potential regional targets at West Mwombezhi, Kamafamba, Sharamba, Chipimpa, and Chalamba. These areas are being explored using shallow aircore and RC drilling to identify large-scale anomalies.

Prospect Resources (ASX:PSC) launched an expanded Phase 3 drilling programme at its flagship Mumbezhi Copper Project.

The campaign involves approximately 26,000m of drilling, comprising a strategic mix of 60 diamond core holes, 30 reverse circulation holes, and 320 scout aircore holes.

The multi-rig approach is designed to rapidly test high-priority targets and define the next generation of copper resources within the region.

A primary focus of the expansion is the Nyungu ‘Hub’, where crews are conducting extension drilling adjacent to the shallower southern up-dip areas of the Nyungu Central deposit.

The programme also targets the Nyungu West prospect zone and a promising geophysical conductor to the northeast.

Beyond the central hub, the company is testing regional targets at West Mwombezhi, Kamafamba, Sharamba, Chipimpa, and Chalamba.

The efforts aim to extend the project’s existing mineral resource estimate, which currently stands at a substantial 173.8 million tonnes at 0.44% copper.

The technical campaign is being bolstered by ground-based geophysical-induced polarisation surveys at Chipimpa and Kamafamba to refine diamond drill targeting.

At the time of reporting, Prospect Resources' share price was $0.42.
