Aurelia Metals: Reweighting a Cobar Basin Business Toward Base Metals and Copper Growth
Aurelia Metals now reads like a company in the middle of a purposeful portfolio shift. Its investor materials describe the business as an Australian mining and exploration company with a strategic landholding in the Cobar Basin of western New South Wales, operating three underground base-metals mines across its Peak and Federation operations. The company’s homepage is even more direct, describing Aurelia as a business with “compelling near-term base metals growth” as it reweights away from its older precious-metals mix.
That shift is easiest to see at Federation. Aurelia says the Federation Mine, about 10 kilometres south of the Hera site, hosts high-grade zinc, lead, gold, copper and silver mineralisation and was officially opened in September 2024. Ore haulage from Federation to the Peak processing plant began in the second quarter of FY25, which means the asset is no longer a future promise; it is already part of the operating base.
The second major leg of the story is Great Cobar. In April 2025, the Board approved development of the Great Cobar Project within the New Cobar Mine at Peak, with a capital estimate of A$91.8 million including contingency. Aurelia has described Great Cobar as a transformational copper growth project, and the project page says operations commenced on 1 July 2025 with first ore targeted in FY28.
That matters because Great Cobar is not being developed as an isolated satellite. Aurelia’s own explanation is that the project has been sequenced to ramp up as Peak South ramps down, helping keep the Peak processing facility full and improving the copper weighting of the broader business. In its FY25 annual report summary, the company said Great Cobar and Federation together underpin a targeted pathway to about 40,000 tonnes per annum of copper-equivalent production by FY28.
The processing side of the strategy is just as important. Aurelia’s Cobar Basin optimisation work is designed to lift effective throughput at the Peak plant from about 800ktpa to 1.1–1.2Mtpa, enabling ore from Federation, Peak South and New Cobar, including Great Cobar, to be processed through a larger and more efficient central plant. The August 2025 optimisation update also outlined crushing and materials-handling upgrades that tie directly into the expanded throughput plan.
That combination gives the business a more coherent industrial shape than a simple list of mines might suggest. Aurelia is not just mining separate deposits around Cobar; it is trying to turn a district-scale land position into a more integrated base-metals platform built around shared processing infrastructure, staged mine sequencing and brownfields expansion. That is one reason the profile feels stronger than a standard mid-tier miner narrative.
The partner layer is also becoming more visible. In October 2024, Aurelia announced a three-year mining services contract with Redpath Australia, showing the company’s willingness to combine internal planning and ownership of strategic assets with specialist underground contracting support where it adds value. In a mining business moving through multiple development and optimisation phases at once, that sort of contractor alignment matters.
The challenge section for Aurelia is less about a single setback than about execution density. The company is ramping Federation, developing Great Cobar, upgrading processing infrastructure and continuing exploration across the basin at the same time. But its own disclosures frame those moving parts as a coordinated growth program rather than a collection of disconnected projects, which is a more constructive and credible way to understand the current phase.
What makes Aurelia a strong feature is that the future is already visible inside the current portfolio. Federation is operating, Great Cobar is underway, Peak remains the central processing hub, and Redpath Australia adds delivery depth to the mining-services side. For a company that once read more like a mixed-metals operator, Aurelia increasingly looks like a Cobar Basin base-metals platform with a much clearer copper future.
