Aurelia Metals Secures Peak Plant Approval, Targets FY28 Ramp

Aurelia Metals secured the final regulatory approval for its Peak processing plant expansion on 14 August 2026, after Cobar Shire Council granted development consent to lift permitted throughput from approximately 800,000 tonnes per annum to 1.2 million tonnes per annum. The council determination, issued to Peak Gold Mines Pty Ltd (Aurelia’s wholly owned subsidiary), removes the last permitting constraint on the processing side of the company’s Cobar Basin growth plan and clears the path for a FY27-FY28 ramp-up across multiple underground ore sources feeding a single expanded hub. For ASX-listed Aurelia Metals (AMI), the consent converts a previously progressing approval into a fully granted capacity uplift of roughly 50%.

What follows covers what the approval means for Aurelia’s operations, how three infrastructure projects supporting the expansion are tracking, and what the expanded plant must deliver to reach the company’s FY28 copper equivalent production target of 40,000 tonnes.

Final council approval removes Peak’s last processing constraint

The determination arrived on 14 August 2026, when Cobar Shire Council issued development consent to Peak Gold Mines Pty Ltd to operate the expanded Peak processing plant at 1.2 Mtpa throughput. The prior permitted capacity sat at approximately 800,000 tonnes per annum, making this a roughly 50% increase in processing headroom.

That figure matters because it closes the regulatory chapter entirely. The processing expansion had been progressing through the approvals pathway for months; with the council’s consent now granted, no further permitting milestones stand between Aurelia and full-capacity operation once the associated infrastructure upgrades are completed.

The NSW mining and resources planning framework, administered under the Environmental Planning and Assessment Act 1979 and the State Environmental Planning Policy (Resources and Energy) 2021, governs how processing plant expansions like Peak’s are assessed, with local council determinations sitting within a broader state-level regulatory architecture.

Interim CEO Martin Cummings framed the consent as a milestone that aligns permitted capacity with the company’s broader ambitions.

“This is an important milestone that brings permitted processing capacity in line with our broader growth objectives across the Cobar Basin operations.” — Martin Cummings, Interim CEO, Aurelia Metals

For investors following Aurelia Metals news, the risk profile has shifted. The question is no longer whether the approval would arrive, but whether the company can deliver the infrastructure program and ramp-up on schedule.

Australian mining industry growth forecasts through 2030 point to the Cobar Basin region as one of the jurisdictions where multi-asset processing consolidation is expected to accelerate, as operators prioritise throughput efficiency over new greenfield capital commitments.

What the Peak processing plant actually does, and why capacity matters here

Peak is not a single-mine processing facility. It operates as the central processing hub for multiple underground ore sources spread across the Cobar Basin, receiving material from different mines at different stages of development and feeding it through a single plant.

This hub-and-spoke model is the foundation of Aurelia’s Cobar Basin Optimisation Study. Three ore sources are designed to feed into Peak:

The copper inventory crisis, with global exchange stocks running at historically thin cover, reinforces why hub-and-spoke processing models that can scale throughput quickly are attracting investor attention across the ASX mining sector.

• Peak South: Existing underground operations, currently producing ore
• Federation: In ramp-up phase, with material volumes building toward steady-state contribution
• New Cobar / Great Cobar: In development, representing the next wave of ore supply for the expanded plant

Run-of-mine stockpiles are already accumulating ahead of the expanded plant coming fully online, signalling active coordination between mining schedules and processing capacity.

That context explains why a single approval at one facility carries company-wide production implications. When Peak’s permitted throughput lifts from 800,000 tonnes to 1.2 Mtpa, it is not one mine gaining headroom. It is the entire multi-asset production system gaining the processing capacity it needs to operate at target scale.

Three infrastructure projects, three different stages of completion

The permitted throughput increase requires physical plant upgrades to match. Three projects form the infrastructure pipeline, each at a different stage of progress.

The tailings thickener is the completed piece. Commissioned in June 2026, the 22-metre unit is already operational and designed to support higher volumes with better unit economics. Then-Managing Director and CEO Bryan Quinn linked the commissioning directly to the expansion’s cost profile.

“The upgrade is expected to support higher throughput while improving recoveries and lowering per-unit processing costs at elevated volumes.” — Bryan Quinn, then-Managing Director and CEO, Aurelia Metals

The tertiary ball mill is the next near-term catalyst. Its commissioning, expected in Q1 FY27, is flagged as critical to lifting grinding capacity into the 1.1-1.2 Mtpa range. Without it, the permitted throughput cannot be physically achieved.

The crushing and materials handling expansion, board-approved in August 2025 with an estimated spend of A$16.4 million, is the longest-dated component. It targets the front end of the processing circuit, designed to remove bottlenecks as underground mine output ramps up. At an estimated ~400ktpa effective throughput uplift, the project represents a capital-efficient debottlenecking investment.

Research into processing capacity investment returns across the critical minerals sector suggests that capital allocated to throughput expansion, rather than greenfield mine development, has historically generated stronger risk-adjusted outcomes, a dynamic that frames the A$16.4 million crushing and materials handling spend in a different light.

The commissioning sequence gives the market quarterly, reportable proof points. The ball mill in Q1 FY27 is the next concrete milestone.

How the expanded plant feeds Aurelia’s 40,000-tonne copper equivalent target by FY28

Aurelia has set a target of 40,000 tonnes of copper equivalent production by FY28, reiterated consistently across ASX filings and company guidance. The company’s filings identify three named drivers for that target:

1. Ball mill commissioning (Q1 FY27): The immediate operational milestone that enables the plant to physically process at the permitted throughput range
2. Throughput ramp trajectory: Quarterly reporting on actual tonnes processed relative to the 1.1-1.2 Mtpa target, providing investors with real-time execution visibility
3. Ore blend from Federation and Great Cobar: The composition and grade of material feeding the plant from multiple sources, which determines the copper equivalent output per tonne processed

According to Aurelia’s ASX filings, Peak plant optimisation and Great Cobar development are described as “key drivers” of the targeted ~40,000 tonnes copper equivalent production in FY28. Management has confirmed that the underlying assumptions behind this target remain unchanged following the council approval.

NSW Resources Regulator copper data identifies the Cobar Basin as the state’s primary copper mineralisation province, providing the regional production context that explains why a throughput expansion at a single Cobar Basin hub can carry significant implications for the state’s overall copper output figures.

Investor-day materials have also referenced a longer-term ambition to grow beyond 50,000 tonnes of copper equivalent, based on a higher copper mix and full utilisation of the expanded Peak plant, though this figure has not been independently verified against formal ASX filings and should be treated as indicative.

The distinction for investors is clear. Permitting is now de-risked. What remains on the critical path is project delivery: the ball mill must commission on time, the ramp-up must track to plan, and the ore blend from Federation and Great Cobar must deliver the grade profile that underpins the copper equivalent calculation.

Past performance does not guarantee future results. Financial projections are subject to market conditions and various risk factors.

The growth story is now an execution story

With the 14 August council consent granted, the risk profile for Aurelia’s Cobar Basin expansion has shifted from regulatory uncertainty to operational delivery. The permitting chapter is closed. What follows is a construction and ramp-up chapter with measurable milestones.

Critical mineral policy gaps at the national level have left processing infrastructure chronically underfunded relative to upstream mine development, which makes company-funded expansions like Peak’s 1.2 Mtpa upgrade particularly consequential for domestic supply chain capacity.

The indicators investors should track in coming quarters include:

• Throughput trajectory: Actual tonnes processed at Peak relative to the 1.1-1.2 Mtpa permitted range
• Ball mill commissioning outcome: Whether the Q1 FY27 target holds and what impact it has on grinding capacity
• Ore blend composition: The grade and volume contribution from Federation and Great Cobar as both ramp into the plant
• Federation and Great Cobar integration progress: Whether mine development timelines remain aligned with the processing expansion schedule

Aurelia Metals trades on the ASX under ticker AMI and on the OTC market under AUMTF. Quarterly ASX updates will provide the next data points on whether the expansion program is converting permitted capacity into actual production growth.

Approval in hand, the Cobar Basin expansion enters its delivery phase

The 14 August 2026 council consent marked the end of Aurelia’s regulatory pathway for the Peak processing plant expansion, lifting permitted throughput to 1.2 Mtpa and clearing the way for the operational phase. Three infrastructure projects, one commissioned and two progressing, form the physical foundation for reaching the company’s FY28 copper equivalent production target of 40,000 tonnes.

The next proof point arrives in Q1 FY27 with the tertiary ball mill commissioning. From there, quarterly throughput reporting will show whether the expanded plant is delivering on the capacity that is now fully permitted.
