Prospect Resources Copper Drilling Results Reveal 1km Mineralisation Zone

Prospect Resources Delivers Strong Copper Results from West Mwombezhi Discovery

Prospect Resources Limited (ASX:PSC) has completed its West Mwombezhi drilling programme at the Mumbezhi Copper Project in Zambia, revealing significant Prospect Resources copper drilling results with a 1km+ copper footprint and continuous near-surface mineralisation. The results showcase the emerging potential of this prospect, which sits just 13km from the flagship Nyungu Central deposit in the world-class Central African Copperbelt.

The 12-hole diamond drilling programme covering 2,217.6 metres has defined two distinct mineralised zones that remain open to the west and south. Furthermore, soil sampling indicates strong copper anomalism extending over 1km south of current drilling. These results will feed directly into a maiden Mineral Resource Estimate scheduled for Q2 2026.

Outstanding Copper Intersections Define Large-Scale System

The Prospect Resources copper drilling results from West Mwombezhi have delivered multiple high-grade copper intersections that demonstrate the robust nature of the mineralisation. These intersections are particularly significant given their shallow depths and substantial widths, indicating potential for low-cost, open-pit mining operations.

The mineralisation occurs predominantly as chalcopyrite within fresh rock, with a relatively thin oxide-transitional zone enhancing the prospect's economic appeal. In addition, the shallow nature of these intersections suggests excellent potential for open-pit extraction methods.

CEO Sam Hosack commented: "Recent diamond drilling has confirmed a continuous, near-surface copper sulphide system extending for more than 1km of strike, remaining open to the west and south. Strong copper-in-soil anomalism continues for over 1km south of the current drill footprint, reinforcing the scale potential of the system."

Understanding Copper Sulphide Mineralisation in the Copperbelt

Copper sulphide mineralisation represents the most economically attractive form of copper deposits for commercial mining. Unlike oxide copper, sulphides contain copper in its primary form – typically as chalcopyrite (copper iron sulphide) – which can be efficiently processed using conventional flotation methods to produce high-grade copper concentrates.

The biotite-rich, kyanite-bearing ore schist hosting the West Mwombezhi mineralisation is characteristic of deposits found throughout Zambia's Central African Copperbelt. This geological setting has produced multiple world-class mines, including First Quantum's nearby Sentinel operation just 25km west of the project.

Key Advantages of This Mineralisation Style

However, the specific advantages of this mineralisation style include:

• High copper recoveries (81-96% achieved at nearby Nyungu Central)
• Coarse grind processing reduces operational costs
• Shallow depths enable low-cost open-pit mining
• Proven metallurgy with established processing routes

The presence of chalcopyrite, sphalerite, pyrrhotite and pyrite identified during geological core logging indicates a robust copper-bearing system. Moreover, this system has potential for additional precious and base metal credits.

Strategic Location Enhances Development Potential

West Mwombezhi's position within the 356 square kilometre Mumbezhi Project area provides significant strategic advantages. For instance, the prospect sits in close proximity to established mining infrastructure, providing numerous operational benefits.

The project benefits from being located on two granted Large Scale Mining Licences valid for 25 years, providing long-term security for development activities. With Prospect holding 90% ownership, the company maintains strong control over future development decisions.

Infrastructure and Operational Advantages

Furthermore, the nearby infrastructure includes:

• First Quantum's Sentinel mine – major copper operation 25km west
• Existing road and power infrastructure serving the region
• Skilled mining workforce available locally
• Established copper supply chains and logistics networks

Systematic Exploration Programme Delivers Results

The West Mwombezhi programme represents a systematic approach to testing regional potential across the broader Mumbezhi licence area. The drilling targeted an approximate 1km² zone with limited historical exploration, supported by comprehensive geological studies.

The Prospect Resources copper drilling results have successfully defined two distinct mineralised zones dipping approximately 15° to the west. In addition, these zones have potential to represent either thrust-related or bifurcating lodes.

Technical Programme Components

The exploration programme incorporated:

• Recent geophysical surveys identifying chargeability anomalies
• Geochemical soil sampling defining copper anomalies
• Shallow aircore drilling completed during 2024-2025
• Surface mapping to understand structural controls

The Cu/Sc (copper to scandium) ratios well in excess of 2:1 in surface geochemistry strongly indicate the presence of copper sulphide minerals. These ratios serve as a key pathfinder for commercial-grade deposits in the Zambian Copperbelt.

The mineralisation is generally hosted within coarse-grained, kyanite-bearing ore schist interleaved with feldspathic gneissic rocks. This geological setting closely resembles the Lumwana-style deposits that characterise the region's most successful operations.

Clear Path to Resource Definition and Growth

Prospect has established a clear timeline for advancing West Mwombezhi toward resource definition. The company has outlined specific milestones for both immediate and medium-term development phases.

Immediate Priorities (Q2 2026)

The near-term development plan includes:

• Complete maiden Mineral Resource Estimate for West Mwombezhi
• Finalise gold deportment studies from current drill samples
• Phase 3 drilling programme (approximately 26,000m) commencing April 2026

Medium-term Development Strategy

However, the longer-term strategy encompasses:

• Initial Scoping Studies to evaluate economic potential
• Regional exploration at Chipimpa, Sharamba, Nyungu West, and Kamafamba prospects
• Integration with existing resource base of 173.8Mt @ 0.44% Cu at Nyungu Central and Kabikupa

The company's systematic exploration approach continues to identify value across the broader licence area. For instance, multiple satellite prospects have been identified for potential open-pit feed to a central processing facility likely positioned near the flagship Nyungu deposits.
