Prospect Resources Reports High-Grade Copper Extensions at Mumbezhi

Prospect Resources Delivers High-Grade Copper Extension at Mumbezhi Project

Prospect Resources Limited (ASX: PSC, FRA: 5E8) has delivered significant high-grade copper results from its Phase 2 drilling programme at the Mumbezhi Copper Project in Zambia's Central African Copperbelt. The company reported that drilling has successfully identified new mineralisation zones and confirmed substantial potential for a larger-scale copper system at the flagship Nyungu Central deposit.

Outstanding High-Grade Results Extend Nyungu Central

Prospect Resources delivers high-grade copper results that demonstrate the standout performance from the latest drilling campaign, particularly from hole NCDD021, which returned 34 metres at 0.88% copper from 128 metres depth. Furthermore, this intersection included an additional 2.7 metres at 0.52% copper from 114 metres. According to the company announcement, this intersection represents a significant shallow, high-grade zone that extends the Nyungu Central deposit to the south.

The drilling targeted the previously under-explored southern extension of Nyungu Central, where copper mineralisation surfaces before being terminated by an east-southeast trending fault. Consequently, the strategic approach has reportedly identified near-surface mineralisation that could substantially enhance the project's economics.

Additional encouraging results from the Phase 2 programme include:

• NCMT001: 8.46m @ 0.34% Cu (sulphide zone) and 6.0m @ 0.42% Cu (oxide zone)
• NCDD017: 2.06m @ 0.33% Cu from shallow depth (oxide zone)

Kabikupa Deposit Shows Continued Promise

In addition to the main results, the company also received final assay results from its dedicated metallurgical hole at the Kabikupa deposit. Moreover, KKMT001 returned 18.6 metres at 0.48% copper from 98 metres depth, including a higher-grade zone of 13.6 metres at 0.56% copper. This metallurgical hole will provide samples for comprehensive testing at Core Metallurgy in Brisbane, with initial results expected in February 2026.

The Kabikupa deposit currently hosts an Inferred Mineral Resource estimate of 20.5 million tonnes at 0.5% copper, contributing to the project's substantial copper inventory.

Understanding Copper Grades and Their Significance

For investors assessing copper exploration projects, understanding grade quality is crucial for evaluating potential economics. However, copper grades are expressed as percentages, with the results from NCDD021 of 0.88% copper over 34 metres representing a significant intersection. Many world-class copper deposits operate at grades between 0.4% to 1.0% copper.

The shallow nature of these intersections carries particular value, as near-surface mineralisation typically requires lower mining costs. Furthermore, reduced infrastructure requirements compared to deeper deposits could significantly enhance the project's economic viability and reduce capital requirements for future development.

Grade Context

• High-grade: >1.0% Cu (premium operations)
• Medium-grade: 0.5-1.0% Cu (typical commercial operations)
• Low-grade: 0.2-0.5% Cu (bulk tonnage operations)
• Sub-economic: <0.2% Cu (generally not viable)

Comprehensive Exploration Pipeline Builds Future Value

Prospect has completed an extensive Phase 2 drilling programme totalling nearly 14,770 metres across 59 diamond holes. Additionally, assay results still remain pending from four holes at Nyungu Central. The programme was supplemented by over 3,500 metres of aircore drilling covering 165 holes, providing cost-effective regional exploration coverage.

"Mumbezhi continues to deliver scale potential, with the shallow intersection returned at the southern end of the Nyungu Central deposit in NCDD021 delivering substantial prospectivity for high-grade, near-surface tonnage growth into next year," said Sam Hosack, Managing Director and CEO.

Key Upcoming Catalysts

The company has outlined several important milestones for the coming months:

Consequently, the company has submitted over 1,200 pulp samples for dedicated gold analysis, which could identify significant by-product potential that would enhance the project's economics through additional revenue streams.

Strategic Position in World-Class Mining Region

Mumbezhi's location in northwestern Zambia places it within the Central African Copperbelt, one of the world's premier copper-producing regions. The project covers 356 square kilometres across two granted Large Scale Mining Licences. For instance, this positioning places Prospect near several major operating copper mines in similar geological settings.

The current combined Mineral Resource estimate across Nyungu Central and Kabikupa totals 107.2 million tonnes at 0.5% copper, containing 514,600 tonnes of copper. Moreover, with Phase 2 drilling results expected to expand these estimates in Q1 2026, Prospect is building a substantial copper inventory that could support significant mining operations.

Advanced Exploration Techniques Drive Discovery

Prospect has implemented sophisticated exploration techniques to maximise discovery potential. Furthermore, the recent comprehensive airborne electromagnetic (AEM) survey identified multiple high-priority conductors at Sharamba and Chipimpa, representing new exploration targets for 2026.

The company's systematic approach combines:

• Diamond drilling for detailed geological understanding
• Aircore drilling for cost-effective regional coverage
• Geophysical surveys for target generation
• Geochemical sampling for anomaly definition

Investment Thesis Analysis

The latest results from Mumbezhi support several key investment considerations when examining how Prospect Resources delivers high-grade copper results:

Scale Potential

With over 500,000 tonnes of contained copper already defined and multiple prospects still being evaluated, Mumbezhi demonstrates potential to become a significant copper producer in the region. However, continued exploration across the extensive land package could further enhance this scale potential.

Near-Surface Economics

The identification of high-grade, shallow copper mineralisation at Nyungu Central could substantially improve project economics. For instance, reducing mining costs and infrastructure requirements creates more attractive development scenarios compared to deeper deposit alternatives.

Exploration Upside

Multiple untested geophysical targets and pending assay results provide substantial exploration upside potential. In addition, new discoveries remain possible across the extensive 356 km² land package.

Strategic Location

The project's position within the Central African Copperbelt provides access to existing infrastructure and a skilled mining workforce. Consequently, this reduces development risks and costs compared to greenfield projects in less established mining regions.

Market Context and Supply Dynamics

The global copper market faces supply constraints as electrification trends drive demand growth. Furthermore, electric vehicles require significantly more copper than traditional vehicles, with some estimates suggesting 80kg of copper per electric vehicle compared to 20kg for conventional vehicles. This supply-demand dynamic creates a favourable environment for new copper discoveries and development projects.

The combination of an established resource base, high-grade extensions, and substantial exploration upside positions Prospect for potential significant value creation as copper demand continues growing driven by global electrification trends.

What Makes These Results Particularly Significant?

The significance of these results extends beyond simple grade metrics. However, the shallow depth of mineralisation, combined with high-grade intersections, creates potential for low-cost mining operations. Moreover, the southern extension of Nyungu Central opens up new areas for resource expansion that were previously untested.

Additionally, the consistency of results across multiple drill holes demonstrates the robustness of the mineralisation system. For instance, multiple intersections at varying depths suggest a substantial and continuous ore body that could support long-term mining operations.
