Revolver Secures A$1.5M in Royalties as Dianne Copper Project FEED Completes

Technical Milestone Achieved at Dianne Copper Mine

Revolver Resources Holdings Ltd (ASX: RRR) has reported the completion of the solvent extraction-electrowinning (SX-EW) Front End Engineering & Design (FEED) for its flagship Dianne Copper Mine Project in northern Queensland. This comprehensive engineering and metallurgical program, including column-scale leach testwork and process flow design, provides a robust technical validation of the project’s viability and informs future process mechanics.

The FEED completion also satisfies a major milestone tied to the A$1.3 million grant awarded by the Queensland Critical Minerals and Battery Technology Fund, supporting the company’s efforts to fast-track development of critical mineral assets in the region.

Funding Strategy Strengthened by Royalty Agreements

In a significant boost to its project-level funding, Revolver secured A$1.5 million through the establishment and sale of three separate 1% gross revenue royalties (GRRs) over the six mining leases comprising the Dianne Copper Mine Project. These royalties provide non-dilutive funding, preserving shareholder equity while underpinning the company’s capital requirements as it advances towards a Final Investment Decision (FID).

The GRRs are perpetual, payable quarterly, and exclude Revolver’s broader exploration tenure, focusing solely on the mining leases associated with the mine recommencement. This approach reflects a strategic balance between securing immediate capital and maintaining upside exposure to exploration success.

Exploration and Project Development Progress

Beyond Dianne, Revolver is progressing exploration activities across its broader portfolio. Follow-up programs are being designed for the Larramore Volcanics Belt, targeting district-scale volcanogenic massive sulphide and intrusive-related gold systems. Meanwhile, at the Osprey Project in northwest Queensland, the company is integrating artificial intelligence overlays with ground-based geophysical surveys to refine and rank multiple high-priority copper targets.

These initiatives underscore Revolver’s commitment to leveraging advanced technologies and geological expertise to unlock value across its tenements, situated in some of Australia’s most prospective mineral provinces.

Corporate Developments and Financial Position

Revolver announced the appointment of Ben Donovan as Company Secretary, bringing extensive ASX compliance and corporate governance experience. The company also utilized its At-The-Market (ATM) equity facility to raise approximately A$116,000 in April 2025, issuing shares at a slight premium to the recent volume-weighted average price.

As at 31 March 2025, Revolver held cash reserves of A$379,000. Post-quarter, the receipt of royalty proceeds and ATM equity raise have bolstered the company’s liquidity position, supporting ongoing exploration and development expenditures.

Looking ahead, Revolver is advancing key workstreams with the aim of delivering a positive FID on the Dianne Copper Mine Project in the coming months, a critical juncture that will shape the company’s trajectory.
