List of Mining Companies in Western Australia

Western Australia’s mining sector is dominated by a small number of large multinational and ASX-listed operators, sitting above a much larger base of mid-tier and junior explorers. The state produced 37.2% of the world’s iron ore in 2024, per Geoscience Australia’s Australia’s Identified Mineral Resources 2025 report, and the three companies below account for the overwhelming majority of that tonnage.

• Rio Tinto — the largest iron ore producer operating in the Pilbara, running mines, rail and port infrastructure across Dampier, Cape Lambert and the Robe Valley. Rio Tinto shipped 326 million tonnes of iron ore from Western Australia in 2025, according to Western Australia’s Department of Trade and Commerce, and has guided FY2026 group iron ore production of 323–338 million tonnes (Rio Tinto Investor Relations).
• BHP — operates the Newman, Yandi, Jimblebar and Mining Area C hubs in the Pilbara under its Western Australia Iron Ore division, and is Australia’s other iron ore major alongside Rio Tinto and Fortescue.
• Fortescue — the third major Pilbara iron ore producer, running the Chichester and Solomon hubs, and Australia’s largest domestically headquartered iron ore company by production volume among the WA-focused independents.
• Gold producers in the Goldfields-Esperance region — a cluster of operators around Kalgoorlie-Boulder, including the Super Pit and surrounding underground and open-pit operations, contributing to Australia’s 290-tonne national gold output in 2024 (Australian Bureau of Statistics, via Geoscience Australia).
• Lithium producers in the south-west and Pilbara — operators at hard-rock spodumene projects supplying battery-grade lithium feedstock; current WA-specific production volumes and export values for lithium are not broken out in a single published figure and are best obtained directly from the Western Australia Department of Trade and Commerce or individual company quarterly reports (see the verification section below).
• Nickel operators — WA is a long-standing nickel sulphide and laterite producing region; for current nickel project status and output trends, see Farmonaut’s dedicated overview of nickel ore production and miners.

This is not an exhaustive company directory — WA also hosts dozens of junior explorers and mid-tier producers across iron ore, gold, lithium, nickel and rare earths that don’t appear in national-level production statistics. Geoscience Australia’s national count of 448 operating mines (as of December 2025) is the closest published figure to a full census; it is not broken down by state or company name in the publicly available summary, so a precise WA-only count requires cross-referencing the Western Australia Department of Mines, Industry Regulation and Safety’s own project register.

Mining Companies in Australia: The National Picture

Mining companies in Australia are heavily concentrated in Western Australia, but the sector extends into Queensland (coal, copper, zinc), New South Wales (coal, copper-gold), South Australia (copper, uranium) and Tasmania (specialty metals). At the national level, mining contributed 13.8% of Australia’s GDP in 2025, according to the US Department of Commerce’s Australia Country Commercial Guide — a share driven overwhelmingly by WA’s iron ore, gold and lithium output.

Australia produced 930 million tonnes of iron ore in 2024 (Geoscience Australia/ABS) and 954 million tonnes in 2025 (US Department of Commerce) — the two figures come from different agencies with different collection methods and reporting years, so treat them as independent data points rather than a single trend line, and check both sources directly if you need a reconciled figure. Iron ore export earnings reached AUD 116 billion in FY 2024-25 (Australian Bureau of Statistics), and gold production stood at 290 tonnes in 2024.

Because Western Australia supplies the large majority of the country’s iron ore and a substantial share of its gold and lithium, most companies that appear on a national “largest mining companies in Australia” list are the same companies operating primarily out of the Pilbara and Goldfields-Esperance regions covered above. The practical distinction is headquarters location, not operating footprint — see the Perth section below.

Mining Companies Headquartered in Perth

Perth is the corporate and logistics hub for Western Australian mining — most major and mid-tier operators active in the Pilbara, Goldfields-Esperance and south-west lithium districts run their WA head offices, exploration teams and corporate functions out of Perth, even where their mine sites sit 800–1,500 km further north or east. Fortescue is headquartered in Perth; Rio Tinto’s iron ore division and BHP’s Western Australia Iron Ore operations both maintain substantial Perth-based operational headquarters distinct from their global corporate seats (Rio Tinto: London/Melbourne; BHP: Melbourne).

Beyond the majors, Perth hosts the ASX-listed mid-tier and junior sector almost in full — gold, lithium, nickel and rare earths explorers and developers overwhelmingly list Perth as their registered office, reflecting the city’s role as the primary capital-raising and technical-services centre for WA resources. A definitive, current list of every ASX-listed company headquartered in Perth is best sourced directly from the ASX company directory or the Western Australia Department of Mines, Industry Regulation and Safety, since new listings, delistings and mergers change this list continually.

What Western Australia’s Miners Actually Produce

Iron ore is by far WA’s largest mining export by both volume and value. Rio Tinto alone shipped 326 million tonnes from Western Australia in 2025 (WA Department of Trade and Commerce), against a national total of 930 million tonnes in 2024 and 954 million tonnes in 2025 — meaning Rio Tinto’s single-company shipments represent roughly a third of the country’s entire iron ore output. Australia held a 37.2% share of global iron ore production in 2024 (Geoscience Australia), a position built almost entirely on Pilbara mines.

Gold is the second major commodity: Australia produced 290 tonnes in 2024, with Western Australia’s Goldfields-Esperance region — anchored by Kalgoorlie-Boulder — supplying the majority of that national total, though the ABS figure cited here is national, not WA-specific; a state-level breakdown is available from the WA Department of Mines, Industry Regulation and Safety’s resources data files.

Lithium, nickel and rare earths make up WA’s critical-minerals portfolio, supplying battery and clean-energy supply chains globally. Current production volumes and export values specifically for WA lithium are not consolidated in a single published figure in the sources reviewed for this article — for up-to-date volumes, check the WA Department of Trade and Commerce’s periodic commodity profiles (the same series that published the 2026 iron ore profile cited above) or individual producers’ quarterly ASX reports. For nickel specifically, see Farmonaut’s nickel ore and nickel miners overview.

Employment and Economic Contribution

Western Australia’s mining sector employed 159,185 people as of February 2025, according to the Australian Bureau of Statistics (via CEIC Data’s employment-by-state-and-industry series). At the national level, mining contributed 13.8% of Australia’s GDP in 2025 (US Department of Commerce), a share disproportionate to its workforce size — reflecting the sector’s high capital intensity and export value per worker relative to labour-intensive industries.

A breakdown of that 159,185-person WA mining workforce by specific commodity — how many work in iron ore versus gold versus lithium versus nickel — is not published as a single figure in the sources reviewed here. The ABS labour force survey series that produces the state-and-industry total does not disaggregate to commodity level in its public release; if you need that split, the WA Department of Mines, Industry Regulation and Safety publishes periodic workforce reports that break out major commodity categories, and is the correct primary source to check.

Geoscience Australia’s count of 448 operating mines nationally (December 2025) gives a sense of the sector’s scale beyond the handful of household-name majors — most of those mines are small-to-mid-tier operations that don’t individually move national production statistics but collectively account for a meaningful share of regional employment, particularly in gold and industrial minerals.

How to Verify These Figures Yourself

Every figure in this article carries a source and a date because mining production, employment and export statistics update on fixed release schedules — using a stale number as if it were current is the fastest way to lose credibility with an informed reader. Here’s where each series comes from and how often it refreshes:

• Employment data — the Australian Bureau of Statistics publishes state-and-industry employment figures monthly via its labour force survey. The 159,185-person figure cited above is a February 2025 snapshot; check the current month’s figure at the CEIC Data / ABS employment series.
• Iron ore shipment and production volumes — Rio Tinto reports quarterly production and shipment figures via its investor relations releases; full-year guidance (such as the 323–338 Mt FY2026 range cited above) is issued and revised through the year. Check current guidance at Rio Tinto Investor Relations.
• National production and export statistics — Geoscience Australia’s Australia’s Identified Mineral Resources report is published annually and is the primary source for national commodity production volumes and Australia’s share of global output.
• Export values — the Australian Bureau of Statistics publishes international trade statistics that underlie the AUD 116 billion FY2024-25 iron ore export figure; more recent financial-year totals become available as ABS releases each year’s trade data.
• Sector-wide economic contribution — the US Department of Commerce’s Australia Country Commercial Guide is periodically updated and is a useful cross-check against Australian government sources for GDP contribution and major-operator summaries.

If a number you need isn’t in this article — WA-specific lithium export values, a commodity breakdown of the 159,185 mining jobs, or a precise count of small versus large operators — that’s a genuine published gap, not an oversight. Go to the primary source named above rather than accepting an estimate from a secondary aggregator.

Exploration Technology: How New Deposits Get Found

Before a company appears on a production list, it typically spends years and substantial capital on exploration — narrowing target zones, drilling, and defining a resource. Traditional ground-based exploration across WA’s vast Pilbara and Goldfields terrain is slow and expensive; satellite-based approaches are increasingly used to narrow search areas before ground crews mobilise.

Satellite-based mineral detection uses multispectral and hyperspectral imagery to screen large, remote areas for the alteration signatures associated with iron, gold, lithium-bearing pegmatites and other target minerals — reducing the ground area that needs physical survey before drilling decisions are made. For projects that need to go further than surface screening, satellite-driven 3D mineral prospectivity mapping supports drilling-angle planning and subsurface modelling ahead of a drill programme.

This matters for the company list above in a direct way: the pipeline of future WA mining companies — the juniors that may become tomorrow’s mid-tier producers — depends on exploration efficiency. Screening large tenement packages by satellite before committing to ground survey lowers the cost of testing a prospect, which is a meaningful factor for smaller, capital-constrained explorers operating alongside the Rio Tinto/BHP/Fortescue majors.

Land, Water and Rehabilitation Obligations

Mining companies operating in Western Australia work under state-mandated land rehabilitation obligations administered by the Department of Mines, Industry Regulation and Safety, covering progressive restoration of disturbed land, closed-loop water management and dust control. These obligations apply across the commodity list above — iron ore, gold, lithium and nickel operators alike carry mine closure and rehabilitation plans as a condition of their mining tenements.

• Progressive rehabilitation: ongoing restoration during operations rather than only at closure, required under WA’s mining approvals framework.
• Water management: closed-loop recycling and groundwater monitoring, particularly significant in the Pilbara’s arid operating environment.
• Infrastructure spillover: rail, port and road infrastructure built for iron ore and lithium haulage is, in some cases, shared with or benefits adjacent regional users, though the extent of that shared use varies by corridor and is set out in individual infrastructure access agreements rather than a single public figure.

For a company-by-company account of rehabilitation performance, mine closure liabilities and environmental compliance, the WA Department of Mines, Industry Regulation and Safety’s annual reporting and individual company sustainability reports are the correct primary sources — no single national figure summarises rehabilitation performance across the whole WA sector in the data reviewed for this article.

Iron Ore Export Value Calculator

Use Rio Tinto’s 2025 WA shipment figure and Australia’s FY2024-25 export value to estimate the export value of a given iron ore tonnage at comparable per-tonne rates.

Assumptions: this calculator applies a single blended AUD-per-tonne export rate derived from your chosen reference basis and Australia’s FY2024-25 total iron ore export value; it does not account for grade differences, freight terms, contract versus spot pricing, or exchange rate movements between shipment and reporting periods. Use it as an order-of-magnitude estimate, not a company-specific forecast.

Frequently Asked Questions

Summary

Western Australia’s mining sector is anchored by three iron ore majors — Rio Tinto, BHP and Fortescue — operating primarily in the Pilbara, alongside gold producers centred on Kalgoorlie-Boulder and a growing lithium and critical-minerals base in the south-west. Rio Tinto’s 326 million tonnes of WA shipments in 2025 and its 323–338 million tonne FY2026 guidance sit within a national iron ore output of 930–954 million tonnes across 2024–2025, giving Australia a 37.2% share of global iron ore production. Nationally, mining supported 13.8% of GDP in 2025 across 448 operating mines, while WA alone employed 159,185 people in the sector as of February 2025.

Most of these figures update on fixed cycles — monthly for employment, quarterly for company production guidance, annually for national resource and export statistics — so the sourcing notes above are as important as the numbers themselves if you’re returning to this page later.
