Evolution Mining agrees $149m deal for Carnaby Resources

Evolution Mining has agreed to acquire Carnaby Resources in a transaction valued at approximately A$213 million, or US$149 million. The agreement is structured as an all-stock deal designed to secure a pipeline of high-grade copper-gold ore specifically for the acquirer’s Ernest Henry operation while simultaneously adding what analysts describe as a substantial and underexplored land package.

Under the terms outlined in separate press releases, shareholders holding Carnaby stock will receive 0.0682 new Evolution shares for every share they currently own. This exchange rate implies an offer price of 77.2 cents per Carnaby share, which represents a premium of 61% over Friday’s closing market price.

The acquisition grants Evolution control of the Greater Duchess copper-gold project, transforming it into a secondary ore source for its processing infrastructure. By utilising spare mill capacity and existing facilities at nearby Ernest Henry, the deal is expected to boost annual copper production by roughly 10,000 tonnes. This approach reduces development risk and capital intensity compared with establishing a standalone operation.

Brian Quast, a mining analyst at BMO Capital Markets, stated that the transaction provides additional growth opportunities for Ernest Henry. Lawrie Conway, CEO of Evolution Mining, highlighted that Greater Duchess’s proximity to Ernest Henry allows the company to increase copper production by utilising latent mill capacity and existing infrastructure. He further noted that combining Carnaby’s Greater Duchess project with its prospective tenement package alongside Evolution’s established presence in North West Queensland offers regional consolidation.

The deal also removes a key element of uncertainty surrounding Greater Duchess, which is situated approximately 70 km south of Ernest Henry near Cloncurry in northwest Queensland. A prefeasibility study released earlier this year had assumed the project would pay processing tolls to Glencore at Ernest Henry. Under Evolution’s ownership, that arrangement will cease because both the mine and processing plant will be under common ownership, potentially improving overall project economics.

James Redfern of RBC Capital Markets remarked that the deal provides an additional source of high-quality copper-gold ore for Evolution. He expects the economics of Greater Duchess can be enhanced under Evolution’s ownership and processing at Ernest Henry. The broker maintained its sector perform rating on Evolution with a price target of A$11.50.

MA Moelis Australia described the acquisition as a modest investment relative to Evolution’s market value of about A$23 billion, providing access not only to additional copper feed but also significant underexplored acreage. The broker noted that for Carnaby, this deal represents value recognition by another corporate entity after the market was previously unwilling to pay higher prices.

Euroz Hartleys acknowledged a competing bid remained possible given strong demand for copper assets around the Mt Isa district. They lowered their target price on Evolution to 77 cents while reaffirming a speculative buy recommendation.

Greater Duchess hosts multiple deposits including Lady Fanny, Mount Hope, Nil Desperandum and Trekelano. Carnaby has spent several years expanding resources through exploration drilling across the district while advancing engineering and development studies. The acquisition deepens Evolution’s exposure to copper, increasingly viewed as a key growth commodity due to demand from electrification, renewable energy and transmission infrastructure.

Evolution said Greater Duchess complements its existing portfolio by providing regional growth opportunities around Ernest Henry. Sydney-based Evolution operates six mines in Australia and Canada including Cowal, Mt Rawdon and Mungari alongside Red Lake in Ontario. The company continues to pursue organic and bolt-on growth while maintaining a focus on Tier 1 mining jurisdictions.

The transaction remains subject to customary conditions including Carnaby shareholder approval, court approval and regulatory clearances. A meeting of Carnaby shareholders is expected by early November paving the way for a mid-November closing. All directors of the Carnaby board intend to vote in favour of the deal as they collectively hold 7.3% of shares.

Shares of Carnaby soared 56% on Monday following news of the takeover proposal before falling slightly Tuesday, valuing the company at about A$206 million. Evolution shares dropped 1.8% during this period.
