Evolution Mining plans A$213 million Carnaby Resources takeover for copper production growth.

Carnaby shareholders receive 0.0682 Evolution shares for each Carnaby share, implying about A$0.772 per Carnaby share, with the deal priced at roughly a 60.4% premium to Carnaby's last close and a 46.2% premium to its 15-day VWAP.
Greater Duchess has a reserve of about 8.4 million tonnes at 1.7% copper, located adjacent to Ernest Henry, enhancing Evolution's ability to feed ore into its existing Ernest Henry operation rather than building a standalone mine.
The acquisition aims to unlock roughly 10 kilotonne per annum of incremental copper by feeding Carnaby ore into Ernest Henry's latent mill capacity, delivering low-cost growth without constructing a new plant.
Post-deal, Carnaby shareholders are expected to own about 0.9% of Evolution, indicating only minimal dilution for Evolution holders.
Evolution plans an updated feasibility study for Greater Duchess within 12–18 months to assess how best to integrate the project with Ernest Henry and maximise low-cost copper production growth.
Evolution Mining has agreed to buy Carnaby Resources in an all-scrip deal worth about A$213 million, the company announced this week. Carnaby shareholders will receive 0.0682 Evolution shares for each share they hold, implying a price of roughly A$0.772 per share — a 60.4% premium to Carnaby's last closing price, according to Kalkine.
The deal hands Evolution a copper-gold project sitting right next to its existing Ernest Henry mine in Queensland. Rather than building a new plant, Evolution plans to feed Carnaby ore into Ernest Henry's spare mill capacity to unlock about 10,000 tonnes of extra copper per year, according to Discovery Alert.
Carnaby's flagship asset is the Greater Duchess copper-gold project, which holds a reserve of about 8.4 million tonnes at 1.7% copper. It sits directly adjacent to Evolution's Ernest Henry operation, making it an unusually tidy fit. Australian Mining Review notes the deal gives Evolution a ready-made ore source without needing a standalone mine or processing facility.
Ernest Henry already has mill capacity that is not fully used. By piping Carnaby ore into that existing infrastructure, Evolution avoids the cost and time of building new plant. That is the core logic of the deal — growth on the cheap, using what is already there.
The 60.4% premium is steep, but Evolution is paying entirely in its own shares rather than cash. After the deal closes, Carnaby shareholders will own about 0.9% of Evolution, according to Kalkine. That is minimal dilution for existing Evolution holders, keeping the financial hit small while still landing a strategic copper asset.
The deal also carries a 46.2% premium to Carnaby's 15-day volume-weighted average price. Rask Media reported that Evolution's share price rose about 3% on the day of the announcement, suggesting the market welcomed the move rather than punishing the acquirer for overpaying.
Evolution is already running what it calls the Bert expansion at Ernest Henry. That project is designed to lift output from the existing underground mine. Adding Greater Duchess ore on top of that expansion could push copper production meaningfully higher without a proportional jump in costs, according to Discovery Alert.
Copper prices have stayed strong globally, giving miners reason to move fast on new supply. A capital-light deal — one that reuses existing mills rather than builds new ones — fits that moment well. Evolution plans to deliver an updated feasibility study for Greater Duchess within 12 to 18 months to nail down the best way to integrate the two operations.
Ernest Henry is already one of Australia's most important copper-gold mines. Adding Greater Duchess and its surrounding tenement package builds a larger regional position for Evolution in northwest Queensland. Kalkine described the move as part of a bold push to reshape Australia's copper-gold race, with Evolution betting on scale and infrastructure over greenfield development.
The transaction is structured as a scheme of arrangement, meaning it needs approval from Carnaby shareholders and the courts before it can proceed. If approved, the combination would create a copper hub in Queensland anchored by long-life infrastructure and a growing ore pipeline — exactly the kind of low-risk growth story Evolution's management has been pitching to investors.
