Revolver Resources Finalises Dianne Mine Layout with SX-EW Procurement Underway
Revolver Resources has completed the detailed 3D earthworks and facilities design for its Dianne Copper Mine Project, advancing procurement for key processing equipment and edging closer to a Final Investment Decision.
- 3D earthworks and site layout finalised with 800,000m3 material movement
- Procurement progressing for Solvent Extraction-Electrowinning (SX-EW) plant components
- Operational scheduling nearing completion ahead of Q4 2026 leach pad loading
- Funding negotiations advancing towards Final Investment Decision in coming months
- First copper cathode production targeted within 12 months of FID
Dianne Project Site Design Reaches Completion
Revolver Resources (ASX:RRR) has locked in the final 3D earthworks and facilities layout for its Dianne Copper Mine Project in north-west Queensland, marking a significant step towards development. The design encompasses about 800,000 cubic metres of earthworks, reflecting a compact footprint that balances operational efficiency with environmental sensitivity. This detailed layout integrates access, utilities, and geography, benefiting from specialist environmental consultations to minimise impact.
SX-EW Facility Procurement Advances
Alongside site design, Revolver has initiated procurement for critical components of the Solvent Extraction and Electrowinning (SX-EW) plant. This new facility will process pregnant liquor solution from heap leach operations and is designed for a nameplate capacity of 5,000 tonnes per annum of copper cathode. The operational schedule covering mining, crushing, heap leaching, and cathode production is nearing finalisation, positioning the company to begin leach pad loading in the fourth quarter of 2026, subject to funding.
Funding and Development Timelines
Revolver is actively progressing negotiations on its preferred funding option, aiming to reach a Final Investment Decision (FID) within the coming months. The timing of this decision remains contingent on securing financing. If achieved, the company expects to produce its first copper cathode within 12 months of FID, maintaining its target timeline for bringing the mine into production.
Strategic Positioning and Regional Potential
The Dianne Copper Mine Project sits within the polymetallic Hodgkinson Province, about 260 kilometres north-west of Cairns. Historically one of the world’s highest-grade copper mines, the project now targets a capital-light heap leach and SX-EW operation leveraging the existing mineral resource. Revolver’s regional exploration continues to test for volcanogenic massive sulphide and intrusive-related gold systems in the adjacent Larramore Volcanics Belt, hinting at further upside potential.
Support from Queensland Critical Minerals Fund
The project benefits from backing by the Queensland Critical Minerals and Battery Technology Fund, aligning with broader strategic interests in supporting battery metals essential for global electrification. This support underscores the project's relevance beyond immediate mining economics, positioning it within Australia's critical minerals supply chain ambitions.
Bottom Line?
Revolver’s progress on detailed design and procurement sharpens the path to production, but funding remains the pivotal hurdle before construction can commence.
Questions in the middle?
- Will Revolver secure the necessary funding to confirm its Final Investment Decision in the near term?
- How will the compact, environmentally conscious design impact operational costs and permitting?
- What potential does ongoing regional exploration hold for extending the mine’s life or resource base?
