Best ASX mining stocks to buy in June

The following ASX 200 mining stocks are solid picks to consider adding to portfolios in June 2026 backed by consistent commodities demand and strong long term production growth opportunities.

Rio Tinto Limited (ASX: RIO) 

Rio Tinto Limited (ASX: RIO) is one of the best ASX 200 mining stocks to buy in June 2026 with a reasonable price/earnings ratio of 20.76 while current annual fully franked dividend yield is 3.28%.
The latest quarterly update showed a 9% year-on-year increase in copper equivalent production which was supported by strong operational performance across the portfolio while Pilbara iron ore production rose 13% and alumina production increased 6%.

The company despite cyclone-related weather disruptions achieved its second-highest first-quarter Pilbara iron ore production since 2018 which highlights the quality and resilience of its iron ore operations.

Management reaffirmed all 2026 production guidance and stated that $650 million of annualised productivity benefits have already been implemented while additional efficiency measures could support future earnings growth.

The commodity environment is supportive as rising AI-driven demand for copper along with higher aluminium prices will be helpful for future revenue growth.

Fortescue Limited (ASX: FMG) 

Fortescue Limited (ASX: FMG) is one of the best ASX 200 mining stocks to buy in June 2026 backed by a fully franked dividend yield of 6.37% along with a modest price/earnings ratio of 11.1 and a market capitalisation of about $59 billion.

The company achieved a strong March 2026 quarter as total iron ore shipments increased 5% year-on-year to 48.4 million tonnes which helped lift shipments for the first nine months of FY26 to a record 148.7 million tonnes.

Cost performance improved as Hematite C1 costs declined 4% from the previous quarter to US$18.29 per wet metric tonne while the balance sheet remained strong with US$4.2 billion in cash despite US$1.3 billion of dividend payments and significant investment in growth projects.
Several recent initiatives support future expansion including the acquisition of Alta Copper and its Canariaco Copper Project in Peru as well as broader critical minerals exploration and further progress towards becoming a diversified resources company.

Fortescue has also increased its focus on decarbonisation through an additional US$680 million investment in green energy infrastructure and is developing a 2.3GW renewable energy network across the Pilbara which is expected to support future industrial demand and data centre growth.

Sandfire Resources Limited (ASX: SFR) 

Sandfire Resources Limited (ASX: SFR) is one of the best ASX 200 mining investments right now with a market capitalisation of approximately $8.38 billion supported by a strong balance sheet.
The company in the March 2026 quarter delivered record financial results which included sales revenue of $408 million and underlying EBITDA of $220 million while increasing its net cash position to $76 million from $13 million at the end of December 2025.

Strong cost control was also evident as MATSA's C1 unit cost declined to a very low $0.29/lb which reinforced Sandfire's competitive position on the global copper cost curve and supported an EBITDA margin of 54%.

Several recent initiatives have improved the growth outlook including the acquisition pathway for the Kalkaroo Copper-Gold Project in South Australia along with a planned ~ $70 million pre-feasibility study regional exploration activities across Spain, Portugal, Botswana and Australia and the development of a 21MW solar facility at Motheo.

FY26 copper equivalent production guidance is maintained at 149kt to 165kt and Sandfire is well placed to benefit from long-term electrification trends and generate substantial shareholder value over the years ahead.
