Copper changes the mix for BHP, but iron still rules

Written by Finn ResearchReviewed by Shivam BharukaReviewed September 13, 2026

Copper now provides just over half of group earnings, shifting the profit mix.
Iron ore remains the main cash engine, led by low unit costs at WAIO.
Jansen potash costs continue to climb, forcing a $2.3 billion impairment on Stage 2.
BHP approved $0.9 billion for the Ministers North iron ore project to sustain volumes.
Western Australia Nickel operations are now under review for potential divestment.

01 Running thesis

A copper pivot funded by iron

The bull case focuses on a copper-led future. Copper now accounts for just over half of earnings. BHP is pushing forward with the Escondida New Concentrator and the Vicuna joint venture, which just secured major tax benefits in Argentina.

The company is also unlocking cash from existing assets. Recent deals, including an Antamina silver stream and a power agreement, brought in $6.3 billion without selling core operations.

The bear case centers on rising project costs and iron ore risks. Demand for iron ore relies heavily on China. More importantly, the Jansen potash project is struggling with capital intensity. Stage 2 costs jumped by $2.0 billion to $6.9 billion, causing a $2.3 billion impairment in FY2026.

The next proof points are clear. Watch the Vicuna Stage 1 investment decision expected by the end of 2026, and the outcome of the Western Australia Nickel review by early 2027.

Aug 2026▼BHP reported severe cost escalations at the Jansen potash project, causing a $2.3 billion impairment for Stage 2. The company approved the Ministers North iron ore project and placed Western Australia Nickel under review for divestment.

Feb 2026→Copper crossed a major line, with just over half of group earnings coming from the copper business. BHP also announced $6.3 billion of cash from Antamina silver streaming and WAIO power agreements, while WAIO costs and Jansen costs moved higher.

Aug 2025→BHP reported a 38 million tonne contained copper resource for Vicuna and kept WAIO at very low cost. The offset was a later FY2028 decision for Copper South Australia and more detail on Jansen cost pressure.

Aug 2025▼The FY2025 filing showed larger Jansen cost and timing risk, with Stage 1 capital moving well above the original plan and Stage 2 first production shifting to FY2031. BHP also kept pruning the portfolio by selling Carajas and exiting Kabanga Nickel.

Feb 2025▲BHP de-risked part of the Samarco overhang through a comprehensive agreement with Brazilian authorities. It also formed the Vicuna joint venture with Lundin Mining to combine Filo del Sol and Josemaria.

Aug 2024▼The transition story gained speed with coal divestments and Jansen Stage 2 approval, but nickel oversupply forced a Western Australia Nickel suspension and impairment. Samarco also remained a large legacy cost.

Aug 2024→The starting view framed BHP as a low-cost iron ore cash machine funding a shift into copper and potash. The key tension was whether future-facing growth could outrun commodity cycles and ore grade pressure.

02 Business model

Big mines, low unit costs

BHP makes money by running very large mines for basic materials. The best assets sit low on the cost curve. This means they can generate cash even when commodity prices fall. WAIO leads globally with unit costs around $17.66 per tonne.

Scale matters in mining. A massive port, rail, and processing system spreads fixed costs over huge volumes. To maintain capacity above 305 million tonnes per year, BHP recently approved the $0.9 billion Ministers North project.

The model suffers when project spending runs out of control or when structural oversupply hits. The company had to suspend Western Australia Nickel and take impairments because of global oversupply and falling prices.

03 Product portfolio

What BHP digs up

Cash cow

Iron ore

Iron ore is the core cash generator. The new Ministers North project will help sustain long-term production levels.

Growth engine

Copper

Copper is the main growth engine and now provides over half of earnings. Escondida and the Vicuna joint venture lead the pipeline.

Option

Potash

Jansen is a massive bet on crop nutrients. Cost overruns have hurt the project, pushing Stage 2 costs up and forcing a major write-down.

Steady

Coal

Coal is shrinking as a portion of the business. BHP sold Blackwater and Daunia, leaving a smaller footprint.

Option

Nickel

Nickel shows the danger of commodity cycles. BHP suspended Western Australia Nickel and is reviewing it for potential divestment by February 2027.

The mix uses FY2025 segment revenue from BHP filings. Copper and iron ore together make up most revenue, while potash has little to no revenue before Jansen starts production.

05 Risk factors

What can break the thesis

China iron ore slowdown

High impact · Medium odds

BHP still relies on iron ore for a huge share of cash flow. A weaker China property or infrastructure cycle can cut steel demand and pull iron ore prices lower. Low costs help, but they cannot entirely offset a large price drop.

We watchChina steel output, iron ore prices, and WAIO realized price trends.

Jansen cost creep

High impact · Medium odds

Jansen is meant to build a new potash pillar. The problem is severe capital intensity. Stage 1 costs climbed to $8.4 billion, and Stage 2 costs recently blew out by $2.0 billion, forcing a $2.3 billion impairment.

We watchJansen budget updates, first production timing, and future expansion costs.

Sticky mining inflation

Medium impact · High odds

Mining requires workers, fuel, contractors, and equipment. Inflation has pushed WAIO C1 costs slightly higher. If labor and contractor costs stay high, margins will narrow even at the best assets.

We watchWAIO C1 cost per tonne, labor settlements, and contractor rates.

Commodity oversupply

Medium impact · Medium odds

BHP already felt this in nickel. Global oversupply forced the suspension of Western Australia Nickel, which is now up for potential divestment. A similar supply wave in copper or potash could hurt returns.

We watchNew low-cost supply in copper, potash, and nickel markets.

Legacy liability shocks

Medium impact · Low odds

BHP reduced uncertainty by signing a comprehensive agreement for the Samarco dam failure. That does not make legacy risk disappear entirely. Large mining liabilities can still require cash payments.

We watchSamarco settlement payments and court updates.

06 Quick answers

In one breath

Is BHP mainly an iron ore company?

Iron ore is still a massive cash source. However, copper has become much more important, producing just over half of earnings in a recent half.

Why does BHP care so much about copper?

Copper is used in power grids, data centers, and electric vehicles. BHP expects long-term demand to grow faster than for older commodities.

What is the Jansen potash project?

Jansen is a large fertilizer project in Canada. It has suffered severe cost overruns, with Stage 1 costs reaching $8.4 billion and Stage 2 taking a $2.3 billion impairment.

What should investors watch next for BHP?

Watch the Vicuna Stage 1 investment decision, WAIO costs, Jansen execution, and the final decision on divesting the nickel business.
