Nzilo Copper Project
A large-scale copper development opportunity in the Central African Copperbelt, advancing toward pre-feasibility and positioned for long-term value creation.
Project Overview
The Nzilo Copper Project is the flagship asset of Dilolo Metal and Resources and represents a significant large-scale copper development opportunity within the Democratic Republic of Congo.
Located within the Central African Copperbelt, one of the most prolific copper-producing regions globally, the project benefits from strategic positioning near major mining operations, established infrastructure, and regional export routes.
The project has demonstrated substantial scale through extensive exploration and technical advancement and is progressing toward pre-feasibility as part of the company’s broader development strategy.
- Geological Mapping: 416 points comprising 24 mapping points and 392 outcrop samples were recorded, trenching across outcrops and soil sampling.
- Regional Airborne Geophysics: strong evidence of the overall structure.
- Geochemical Sampling – 77 stream sediment samples were collected. 18 trenches were excavated. 491 pits of which 336 have analysis results for Cu and other elements. 518 rock samples were collected. 1,823 soil samples were taken.
- Drilling: 26 diamond drilling boreholes of depths between 34.5m and 497.3m were drilled.
- Average Cu content of between 0.8% and 1.7%

JORC-Compliant Mineral Resource
The Nzilo Copper Project hosts a substantial JORC-compliant mineral resource, demonstrating both scale and development potential across multiple mineralised zones.
Main resource
The March 2026 mineral resource update outlines a combined resource of 1.43 billion tonnes at an average grade of 0.50% copper, containing 7.11 million tonnes of copper metal.
Geology & Mineralisation
The Nzilo Copper Project comprises multiple mineralised zones with strong geological continuity and significant scale.
Mineralisation is hosted within favourable stratigraphic units associated with the Central African Copperbelt and demonstrates consistent copper grades across both the Southwest and Northeast orebodies.
The project remains open for further exploration, with additional upside potential identified in under-drilled strike extensions and northern target zones.
Exploration Programme
Dilolo Metal and Resources commenced its structured exploration drilling programme in July 2024, significantly expanding the geological database and improving confidence in the mineral resource model.
The exploration programme has focused on systematic drilling, geological mapping, geochemical sampling, and geophysical interpretation to support resource growth and project advancement.
- 148 DMR boreholes completed
- 32,362 metres drilled
- 174 total boreholes in geological database
- 38,526 total metres drilled
Technical Advancement
Metallurgical Pathway
Preliminary metallurgical work indicates the deposit comprises a mixed leachable and refractory system, supporting multiple potential processing routes.
Current technical studies indicate three distinct metallurgical domains, supporting the evaluation of:
- Heap leach processing
- Flotation processing
- Hybrid processing strategies
Open Pit Development Potential
Pit optimisation studies completed on the Northeast and Southwest orebodies support the project’s open-pit development potential.
Initial geotechnical work supports favourable pit slope angles, while simple orebody geometry supports efficient mining and long-term operational scalability.
These studies continue to support the project’s advancement toward pre-feasibility and development planning.
