Highlights

  • Evolution Mining offered to acquire Carnaby Resources via an all-scrip scheme at approximately a 60% premium to unaffected trading levels.
  • The Scheme Booklet was dispatched to shareholders in late September 2026 with an independent expert ruling the deal fair and reasonable.
  • A Pre-Feasibility Study completed in March 2026 outlined an initial open-pit and underground copper-gold mining operation at Greater Duchess.
  • Greater Duchess covers approximately 1,900 square kilometres south of Mt Isa, hosting the Mount Hope, Nil Desperandum, and Trekelano deposits.

A 60% takeover premium from a major ASX gold producer is a powerful statement of intent — and Evolution Mining's all-scrip bid for Carnaby Resources (ASX:CNB) is precisely that, putting a tier-1 valuation on the Greater Duchess copper-gold project in northwest Queensland ahead of a shareholder scheme vote.

Corporate Transaction and Market Performance

Carnaby Resources traded at A$0.875 per share on 2 October 2026, representing a market capitalisation of A$241.6 million. The 108.33% gain over the trailing 12 months was driven entirely by corporate takeover interest from Evolution Mining Limited, one of Australia's major gold producers.

In late September 2026, Carnaby formally dispatched the Scheme Booklet to shareholders. The independent expert concluded the scheme is fair and reasonable and in the best interests of shareholders in the absence of a superior proposal.

Greater Duchess Copper-Gold Project

The underlying asset that attracted Evolution Mining's bid is the 100%-owned Greater Duchess Copper-Gold Project, covering approximately 1,900 square kilometres south of Mount Isa and Cloncurry. Centred on the Mount Hope, Nil Desperandum, and Trekelano deposit clusters, Greater Duchess hosts a JORC-compliant Mineral Resource characterised by broad, continuous chalcopyrite-pyrite mineralisation within structurally complex shear corridors.

A Pre-Feasibility Study completed in March 2026 outlined an initial open-pit and underground mining operation delivering high-margin copper-gold concentrates.

Strategic Logic for Evolution Mining

The proximity of Greater Duchess to Evolution's operational Ernest Henry copper-gold mine created compelling regional processing synergies. By integrating Greater Duchess ore into existing regional infrastructure, Evolution can unlock significant capital savings and eliminate the requirement to construct a standalone processing plant.

Commodity Dynamics and Scheme Terms

Copper and gold represent the twin commercial pillars of Greater Duchess. Under the scheme terms, Carnaby shareholders receive Evolution shares at an implied premium of approximately 60% over unaffected trading levels, providing ongoing equity participation in a diversified ASX 100 gold-copper producer.

Key Risks

The scheme remains subject to approval by Carnaby shareholders at a meeting scheduled for late October or early November 2026 and final sanction by the Federal Court of Australia. If the scheme fails to achieve the requisite 75% voting threshold, Carnaby shares would likely retrace to standalone trading levels. Project financing requirements, environmental permitting approvals, and copper and gold price volatility represent standalone operational risks.
