Copper is changing BHP, but iron still matters

01 Running thesis

A copper pivot funded by iron

The bull case is that BHP is becoming less of a pure iron ore story. Management said just over half of earnings in the latest half came from copper. That is a major milestone for a miner that has long depended on Western Australia iron ore.

BHP is also finding cash inside its own asset base. It announced $4.3 billion from a silver streaming deal tied to Antamina and $2 billion from a WAIO power agreement. Together, that is $6.3 billion of cash without selling the whole core business.

The bear case is still serious. Iron ore is tied to China, especially buildings and infrastructure. WAIO is still low cost, but C1 costs rose to $17.66 per tonne. Jansen potash also looks more expensive, with the Stage 1 estimate now at $8.4 billion.

The next proof points are simple. Watch the Vicuña Stage 1 final investment decision, progress on up to $10 billion of capital unlock ideas, and the FY2028 decision path for Copper South Australia.

Feb 2026Copper 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 2025BHP reported a 38 million tonne contained copper resource for Vicuña 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 2025The 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 Carajás and exiting Kabanga Nickel.
Feb 2025BHP de-risked part of the Samarco overhang through a comprehensive agreement with Brazilian authorities. It also formed the Vicuña joint venture with Lundin Mining to combine Filo del Sol and Josemaria.
Aug 2024The 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 2024The 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 world needs. Its best assets sit low on the cost curve, which means they can still earn cash when commodity prices fall. WAIO is the clearest example, with recent C1 costs of $17.66 per tonne.

Scale matters in mining. A large port, rail, mine, and processing system can spread fixed costs over huge volumes. BHP approved about $0.9 billion for a sixth car dumper at Port Hedland to help keep WAIO capacity above 305 million tonnes per year.

The model breaks when prices fall faster than costs, or when project spending runs ahead of plan. FY2025 revenue was $51.3 billion, down 8% from FY2024, mainly because iron ore and coal prices were lower. Inflation also added $538 million of cost pressure to underlying EBITDA.

03 Product portfolio

What BHP digs up

Cash cow

Iron ore

Iron ore is still the core cash generator. WAIO remains very low cost, but demand depends heavily on China.

Growth engine

Copper

Copper is now the main growth story and has crossed half of group earnings. Escondida and Spence are key assets, with Vicuña adding a larger future option.

Option

Potash

Jansen is a pre-production bet on crop nutrients. First production from Stage 1 is expected around mid-2027, but cost overruns have reduced the margin for error.

Steady

Coal

Coal is being reduced and reshaped. BHP sold Blackwater and Daunia, while New South Wales Energy Coal has approval to operate until 2030.

Option

Nickel

Nickel shows how hard commodity cycles can bite. BHP suspended Western Australia Nickel and exited Kabanga after oversupply hurt the market.

Steady

Capital recycling

BHP is monetizing parts of its asset base without fully exiting them. The Antamina silver stream and WAIO power agreement are the latest examples.

04 Business segments

Still a two-pillar business

Iron Ore45%flat
Copper44%growing fast
Coal10%declining
Other and unallocated1%flat

The mix uses FY2025 segment revenue from BHP's annual report and results materials. 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 large share of revenue and cash flow. A weaker China property or infrastructure cycle can cut steel demand and pull iron ore prices lower. Low costs help, but they do not protect profit from 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 for BHP. The problem is that Stage 1 costs have already moved up to $8.4 billion after inflation and lower productivity. If costs rise again or first production slips, the potash story loses value.

We watchJansen Stage 1 budget updates, first production timing, and Stage 2 schedule to FY2031.

Sticky mining inflation

Medium impact · High odds

Mining needs workers, fuel, energy, contractors, explosives, and equipment. BHP said inflation hit the cost base by $538 million in FY2025, and WAIO C1 costs rose to $17.66 per tonne. If labor and contractor costs stay high, margins can narrow even at good assets.

We watchWAIO C1 cost per tonne, labor settlements, contractor costs, and diesel or power costs.

Commodity oversupply

Medium impact · Medium odds

BHP already felt this in nickel. Global oversupply forced the temporary suspension of Western Australia Nickel and led to an impairment in FY2024. The same kind of supply wave in another commodity could hurt prices and capital returns.

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

Legacy liability shocks

Medium impact · Low odds

BHP reduced a major uncertainty by signing a comprehensive agreement tied to the Samarco dam failure. That does not make legacy risk disappear. Large mining liabilities can still involve cash payments, legal changes, or reputational damage.

We watchSamarco settlement payments, court updates, and any new environmental provisions.
06 Quick answers

In one breath

Is BHP mainly an iron ore company?

Iron ore is still one of BHP's biggest cash sources. But copper has become much more important, and management said copper produced just over half of earnings in the latest half.

Why does BHP care so much about copper?

Copper is used in power grids, buildings, data centers, electric vehicles, and other electrification projects. BHP is leaning into copper because it expects long-term demand to grow faster than for some older commodities.

What is the Jansen potash project?

Jansen is BHP's large potash project in Canada. Potash is used in fertilizer, so it links BHP to food production, but Stage 1 costs have risen to $8.4 billion.

What should investors watch next for BHP?

Watch the Vicuña Stage 1 investment decision, WAIO costs, Jansen execution, and China steel demand. Those signals show whether the copper pivot is gaining ground or the old iron ore risks are taking over.
