Revolver finalises Dianne copper site layout ahead of final investment decision

• Final Dianne 3D earthworks and facilities layout complete.
• Compact design minimises operational footprint.
• Procurement activities for key SX-EW facility items in progress.
• Advancing preferred Dianne funding option.

Revolver Resources (ASX:RRR) continues to hit key milestones ahead of a targeted final investment decision (FID) and full-scale development commencement on its Dianne copper mine project in north-west Queensland.

The final 3D earthworks and facilities layout for the proposed project features a design with a highly granular level of detail within a “tightly defined and well-understood” scope.

At the same time, Revolver has started procurement for key elements of the Solvent Extraction and Electrowinning (SX-EW) process facility to be installed at Dianne.

This new plant will process the pregnant liquor solution from the heap leach and is set to have a nameplate production capacity of 5.0 ktpa copper cathode. Operational scheduling across open pit mining, crushing and processing (leach pad activities through to plated metal production) is also approaching finalisation.

In late May, Revolver contracted local Cape York services business, CEMACC, to undertake all civil earthworks activities required for the development of Dianne, including site roads, drains, dams, leach pads, and material importation area.

Following completion of these development activities, CEMACC will then transition into the provision of mining, crushing and leach pad loading services for Dianne.

Major equipment to be supplied by CEMACC and delivered includes: a 70-tonne hydraulic excavator, 50t hydraulic excavator, D9 dozer, 140 grader, spur 45t articulated dump trucks, and water and support trucks.

The broader Dianne project is located in northern Queensland, approximately 260km north-west of Cairns. Subject to securing final project funding, Revolver remains on track for initial leach pad loading during Q4 2026.

The Dianne deposit, which previously hosted one of the highest-grade operating copper mines in the world, is in the eastern part of the Dianne project. Revolver’s Dianne project is focused on a low capital cost, heap leach / SX-EW development of the existing mineral resource at the Dianne deposit.

RRR is steady at 6.9¢. Mkt cap $21.05M.
