ASX Commodities: Copper Surges While Lithium Seeks a Floor

The August 2026 reporting season has delivered a jolt to the ASX resources sector. In specific pockets of mining, earnings beats are not incremental; they are transformative, with profits tripling and cash positions swelling by hundreds of millions of dollars in a single year.

The driving forces are not a mystery. Electrification and AI infrastructure are pulling copper demand in directions the market was not pricing two years ago, while lithium, left for dead after a brutal supply glut, is showing early signs of finding a floor. The result is a widening gap between structurally favoured metals and everything else, and that gap is forcing a rethink of how investors allocate capital across Australian commodities stocks.

What follows here is a clear framework for evaluating the copper and lithium opportunities emerging from this reporting season. It draws on the actual FY26 numbers from three ASX names, each with a distinct risk profile, and on the positioning logic of portfolio manager James Garish at Market Partners, who is putting real capital behind these themes right now.

Sandfire Resources and the premium on pure copper leverage

Sandfire Resources did not just beat expectations in FY26. It delivered the kind of result that forces the market to permanently re-categorise a company.

The numbers tell the story quickly:

• Record sales revenue of approximately US$1.7 billion
• Underlying EBITDA of US$867 million
• Underlying profit of roughly US$350 million, up approximately 214% year-on-year
• A fully franked final dividend of AUD$0.35 per share, the first in more than four years
• A net cash position of approximately US$353 million after full repayment of all debt facilities

Investors rewarded the result with a share price gain of around 20% across the reporting month, carrying the stock to fresh all-time highs. With approximately 70% of revenue tied to copper, Sandfire offers the most direct leverage to the copper price among ASX-listed miners.

The structural case underpinning Sandfire’s re-rating is not company-specific; copper demand growth from electrification and AI data centre buildout is creating a sustained pricing floor that pure-play producers are only beginning to fully monetise.

That directness is exactly what makes the entry decision complicated. James Garish, portfolio manager at Market Partners, owns the copper thesis and has benefited from Sandfire’s re-rating over recent years. But his current stance is one of discipline rather than pursuit.

Garish distinguishes clearly between a high-quality business and an attractive entry point, noting that the gap between the two tends to be widest precisely when results are most impressive.

The read for your portfolio is straightforward. Sandfire’s tripled profits tell you how powerful pure copper leverage is in this market environment. Whether chasing the stock at all-time highs fits your personal risk tolerance, or whether patience and a pullback would serve you better, is a separate question entirely. Business quality and entry attractiveness are not the same thing, and this reporting season is a reminder of why that distinction matters most during late-cycle rallies.

South32 and the multibillion-dollar base metals pivot

If Sandfire shows you what single-asset copper leverage looks like on the income statement, South32 shows you what the copper thesis looks like in the boardroom.

In July 2026, South32 agreed to sell the bulk of its aluminium value-chain assets to Alcoa for an implied enterprise value of up to US$5.6 billion. The deal structure includes approximately US$3.1 billion in cash, roughly US$1 billion in Alcoa equity, assumed debt, and contingent payments linked to alumina prices. This is not a minor portfolio trim. It is a deliberate, multibillion-dollar reshaping of the company toward copper, zinc, silver, and lead.

The pivot is being executed from a position of strength. FY26 underlying earnings came in at approximately US$1 billion, up roughly 55% year-on-year. Ordinary dividends rose 55% to 9.3 US cents per share. Following completion of the Alcoa transaction, an estimated 85% of South32’s pro-forma earnings are expected to come from base and precious metals.

What this tells you about where institutional capital is concentrating is worth noting. When a company with South32’s balance sheet voluntarily exits a profitable commodity segment worth billions to concentrate on copper and base metals, it is a signal about conviction. Growth projects in Sierra Gorda (Chile) and Hermosa (the United States) sharpen the forward copper exposure further.

For your portfolio, South32 offers a lower-volatility pathway into the same copper thesis. Less torque to the copper price than Sandfire, but more diversification, a larger balance sheet, and upside driven by capital reallocation rather than single-asset leverage.

Understanding commodity cycle inflections

Copper and lithium are both cyclical commodities, but they sit at very different points in their respective cycles right now. Understanding where a commodity sits in its cycle is what separates strategic positioning from reactive trading.

Commodity cycles tend to move through three distinct phases:

1. Capitulation: Prices fall below production costs for marginal producers. Projects are deferred or cancelled. Capital exits the sector. Sentiment reaches its worst point, and weaker operators shut down or restructure.
2. Trough-to-repair: Supply destruction (fewer mines, lower output, reduced exploration spending) gradually tightens the market. Prices stabilise and begin to recover. Stronger producers with low costs and large balance sheets start generating cash again, while weaker competitors remain sidelined.
3. Growth phase: Demand catches up with constrained supply. Prices rally. Margins expand rapidly for survivors. New capital floods back in, eventually planting the seeds of the next oversupply cycle.

The institutional approach to these cycles is what Garish’s positioning across Sandfire, South32, and Pilbara Minerals illustrates. Thesis-driven entry discipline means building positions based on a macro and valuation view before the confirming data arrives, rather than waiting for earnings prints and then chasing.

This distinction matters for how you time your own entries. Early-cycle positioning captures the recovery. Late-cycle momentum chasing, buying when results are at their most impressive, carries the highest risk of paying peak prices. Knowing which phase a commodity is in gives you the confidence to act before the crowd or, just as importantly, to wait when the crowd is already ahead of you.

The three-phase cycle model described here maps onto broader commodity supercycle dynamics, where supply destruction and demand acceleration interact over multi-year horizons rather than the shorter timeframes most equity investors typically model.

Pilbara Minerals and the anatomy of a lithium floor

Lithium equities experienced a sharp correction after the post-pandemic rally as new and reactivated production flooded the market. Pilbara Minerals, the ASX’s largest pure-play lithium producer, was not spared. But FY26 delivered the kind of numbers that suggest the worst of the excess supply shock has been absorbed.

The turnaround is stark:

• Revenue of approximately A$1.93 billion, up roughly 152% year-on-year
• Underlying EBITDA of approximately A$1.137 billion, up more than 1,000%, with margins near 59%
• Net profit of approximately A$526 million, swinging from a loss of roughly A$196 million in FY25
• Production of approximately 879,000-880,000 tonnes of spodumene concentrate (the raw lithium mineral product shipped to refiners), up about 17%
• Cash of approximately A$2.29 billion, with total liquidity approaching A$2.8 billion

That cash buffer is the number that matters most in a cyclical downturn. It tells you Pilbara can absorb further price volatility, invest in staged growth, and outlast higher-cost competitors who lack the balance sheet to survive a prolonged trough. Scale and low operating costs are what separate the survivors from the casualties in battery metals, and Pilbara’s FY26 metrics place it firmly in the survivor category.

Confirming the thesis

Garish initiated a position in Pilbara before these results were published, based on a macro view that lithium was transitioning from severe oversupply toward a more balanced market. The FY26 earnings served as confirmation of that thesis, not the trigger for the trade. This is the institutional approach in action: position ahead of the data, then let the data confirm or deny.

Garish’s pre-results entry into Pilbara was built on a view about lithium price recovery that goes beyond a single producer’s cost curve, incorporating Chinese demand signals, battery energy storage system (BESS) buildout, and the timeline for excess inventory to clear from the market.

The risks that remain are real. EV adoption rates could slow. Battery chemistry changes, particularly the shift toward lithium iron phosphate (LFP) cells in some markets, could alter demand profiles. New project approvals could tip the supply balance back toward oversupply. Lithium is moving from capitulation toward repair, but it has not entered a confirmed growth phase. Active risk management remains necessary even as the sector’s outlook improves.

What Pilbara’s result offers you is a case study in how to play volatile commodity sectors safely: identify the lowest-cost, best-capitalised producer, enter on a thesis rather than a headline, and maintain the discipline to manage risk even when the numbers are improving.

Aligning your portfolio with the 2026 commodity reality

The August 2026 reporting season has handed investors three distinct ways to play the resource sector, each with its own risk profile: Sandfire for high-beta, pure copper leverage; South32 for diversified base metals exposure with a copper tilt; and Pilbara Minerals for leveraged exposure to a potential lithium recovery.

The common thread across all three is that strong fundamentals alone do not make a position. Entry discipline, timing, and valuation awareness are what separate strategic positioning from momentum chasing. Garish’s approach, owning the copper thesis but exercising patience at all-time highs, entering lithium before the confirming data, illustrates this consistently.

Review your current resource weightings against these shifting institutional trends. Copper’s structural demand story from electrification and AI infrastructure is being confirmed by real earnings growth. Lithium is showing credible signs of a trough. The question is not whether these themes are real; the reporting season answered that. The question is whether your portfolio is positioned to capture them at prices that leave room for returns.

The earnings beats from Sandfire, South32, and Pilbara are consistent with a broader ASX materials sector outlook that points to accelerating earnings revisions across resource names through the second half of 2026, with base metals producers leading the revision cycle.
