Prospect Resources Confirms Expanding Copper System at West Mwombezhi in Zambia

Prospect Resources Reports Strong Copper Drill Results at Mumbezhi Project as Maiden Resource Estimate Targets 2026

Australian mining company Prospect Resources Limited has received final assay results from Phase 2 diamond drilling at the West Mwombezhi prospect within the Mumbezhi Copper Project in Zambia, confirming the presence of a continuous near-surface copper sulphide system extending for more than one kilometer along strike.

The latest drilling campaign has delivered several new mineralized intersections, including:

• 8.9 meters grading 0.78% copper from 54.6 meters, including 7.0 meters at 0.93% copper
• 6.7 meters grading 0.57% copper from 86.0 meters, including 4.2 meters at 0.75% copper
• 5.8 meters grading 0.44% copper from 145 meters

These results strengthen the geological case for a growing copper system at West Mwombezhi and support the prospect’s emerging scale potential.

According to the company, the mineralization remains open to the west and south, indicating significant room for resource expansion through further drilling.

Strong Exploration Signals Beyond Current Drilling

In addition to the drilling results, soil sampling programs have identified strong copper anomalies extending more than one kilometer south of the existing drill footprint.

These geochemical indicators suggest the presence of additional mineralized zones that have yet to be fully tested.

The data generated from this exploration work will contribute directly to the preparation of a maiden Mineral Resource Estimate (MRE) for the West Mwombezhi prospect, scheduled for completion in the second quarter of 2026.

This upcoming estimate will build on the recently updated resource base for the broader Mumbezhi project, which currently hosts approximately 173.8 million tonnes of ore grading 0.44% copper, representing about 772,000 tonnes of contained copper.

Part of a District-Scale Copper Opportunity

The Mumbezhi Copper Project is located in the heart of the Central African Copperbelt, one of the world’s most prolific copper-producing regions.

The project covers roughly 356 square kilometers under two large-scale mining licenses and lies near major operating mines in northwestern Zambia.

Exploration across the project has been conducted in multiple phases. Phase 2 drilling, completed in late 2025, involved more than 18,000 meters of drilling across several targets, including Nyungu Central, Kabikupa, and regional prospects such as West Mwombezhi.

Managing Director and Chief Executive Officer Sam Hosack said the latest results reinforce the project’s long-term growth trajectory.

“We are encouraged by the latest results from West Mwombezhi, which point to a compelling emerging opportunity that enhances the broader regional potential at Mumbezhi,” he said.

“Recent diamond drilling has confirmed a continuous, near-surface copper sulphide system extending for more than one kilometer of strike, remaining open to the west and south.”

He added that the West Mwombezhi target, along with other exploration zones across the license area, offers significant upside potential for additional copper, as well as possible gold and cobalt mineralization.

Next Phase: Resource Growth and Development Planning

The company plans to launch a Phase 3 drilling campaign beginning in the second quarter of 2026, aimed at expanding known deposits and advancing the project toward economic evaluation.

Industry analysts note that the continued growth of the Mumbezhi resource base aligns with Zambia’s national strategy to significantly increase copper production, targeting output of up to 3 million tonnes per year by 2031.

If exploration success continues, the Mumbezhi project could evolve into a major new copper development within the Copperbelt, supporting regional mining investment, infrastructure development, and export growth.

Strategic Significance for the Copperbelt

The confirmation of expanding copper mineralization at West Mwombezhi highlights the ongoing exploration momentum in Zambia’s mining sector at a time of rising global demand for copper particularly for renewable energy systems, electric vehicles, and power infrastructure.

With multiple targets still under evaluation and mineralization remaining open in several directions, the Mumbezhi project is increasingly viewed as a potential district-scale copper asset capable of supporting long-term production growth in the region.
