The project is expected to create approximately 100 new jobs for enabling works. Once in operation, the mine is projected to create nearly 1,500 jobs.

The mine has an expected mine life of 40 to 60 years.

The planned processing method involves crushing the ore underground before transporting it to a surface concentrator complex. The concentrator will use a wet grinding process to create a slurry, which then undergoes froth flotation with water, reagents, and air to separate the copper minerals. The resulting copper concentrate, containing about 29-31% copper, will be filtered and sent to customers for smelting and refining. Molybdenum concentrates will also be produced, packed, and trucked to market.

A significant milestone was reached in March 2026 with the completion of a federal land exchange, transferring over 2,400 acres of land to Resolution Copper. This allows the project to move to the next phase of technical work and development planning. The U.S. Forest Service signed the record of decision for the project on March 16, 2026, and released the final environmental impact statement in June 2025. The project is advancing through the permitting process, which will be followed by a decade of construction before mining can begin.

Production overview - 2025: copper 368000 t, zinc 383407 t, silver 16 Moz; 2024: copper 429000 t, zinc 273000 t, molybdenum 8000 t, silver 1.3 Moz.

The operation employs a truck-and-shovel method in an open pit. Ore is crushed in-pit and then transported via a 2.7-kilometre tunnel to a coarse ore stockpile. The processing plant uses grinding and flotation to produce separate copper, zinc, molybdenum, and lead-bismuth concentrates. Copper and zinc concentrates are transported through a 302-kilometre pipeline to the Huarmey Port for shipment. Molybdenum and lead-bismuth concentrates are transported by truck.

A Modification of the Environmental Impact Assessment (MEIA) was approved in February 2024 for a US$2 billion investment to extend the mine's life from 2028 to 2036. This project, known as the "Antamina Replenishment," includes expanding the open pit footprint, deepening the pit by an additional 150 metres, and optimising waste dumps and the tailings dam. Construction is expected to begin in 2025. The expansion also involves optimising the processing plant to a capacity of 208,000 tonnes per day.

Approximately 3,500 jobs annually during construction and over 900 full-time roles once operational.

The project is located approximately 140 kilometres east of Saskatoon. The mine will use the long room and pillar mining method. The final product will be red standard and red granular muriate of potash (MOP) with a guaranteed minimum of 60% potassium oxide (K2O).

Production overview - 2021: potassium 1070000000 t.

The processing method will involve crushing, scrubbing, conditioning, flotation, and de-brining to separate potassium chloride and sodium chloride crystals. The design includes fine and coarse flotation with on-stream analysis and crystallisation to recover fine potash from waste streams. An Integrated Operations Centre in Saskatoon will oversee all equipment and processes from the mine to the port using real-time data.

The underground mining fleet will be more than 80% electric. This includes a large fleet of multi-use battery-electric vehicles from Normet, 10 underground battery-electric loaders and one electric tethered loader from Sandvik, and cable-connected electric borer miners (Sandvik MF460). The mine will use a network of conveyor belts to transport ore to the shaft area.

As of January 2026, Stage 1 of the Jansen project was 75% complete. Stage 2 was 14% complete. BHP is advancing construction of both stages.

The mine was placed on temporary care and maintenance in November-December 2023, following the expiry of its environmental licence for water extraction at the end of 2023. The last production of copper cathodes occurred in November 2023.

Production overview - 2024: copper 11000 t; 2023: copper 35000 t.

The mine produced copper cathodes through a process of leaching and solvent extraction and electrowinning (SX-EW). BHP is assessing the application of novel leaching technologies for a potential restart.

BHP is actively working towards restarting the mine. A US$60 million project involving drilling and prospecting has been submitted to the environmental review agency to gather information for the mine's future. The company is evaluating a reopening starting in 2028, with a potential investment of US$1.3 billion to allow operations to continue for at least another 20 years. A larger project, with investments estimated between US$2.3 billion and US$3.2 billion, could boost annual copper output to 145,000 tonnes and extend operations beyond 2031. A final investment decision for this larger project is anticipated in 2028.

As of November 2024, 32% of the employee workforce is locally based in the Antofagasta Region, with 68% being fly-in, fly-out. Over 40% female representation and approximately 10% Indigenous employee participation.

Production overview - 2024: copper 255600 t; 2023: copper 240000 t.

The operation uses both leaching and concentrator flow sheets, producing copper cathodes through SX-EW from oxide and sulphide ore. A new copper concentrator plant with a throughput of 95,000 tonnes per day produces copper and molybdenum concentrate.

The mine operates with a fully autonomous haul truck fleet of 33 trucks and 5 autonomous drills (Pit Viper 351 models).

The Spence Growth Option (SGO) project (US$2.46 billion) extended mine life by 50 years. Modifications to the concentrator plant began in August 2022, expected completion FY24. BHP is considering projects to improve recovery by 3-7% and increase throughput to 105 ktpd from 95 ktpd.

3,935 direct workers (as of February 2024). There are a total of 10,567 workers on site, comprising 3,621 employees and 6,946 contractors, according to a report with a follow-up assessment in October 2022.

Production overview - 2024: copper 614400 t.

The mine has two open pits, Escondida and Escondida Norte, which supply ore to three concentrator plants (Los Colorados, Laguna Seca 1, and Laguna Seca 2). It also has two leaching operations for oxide and sulphide ores, which include solvent extraction and electrowinning (SX/EW) plants to produce copper cathodes. The operation uses desalinated water from two plants at Puerto Coloso, which is pumped to the mine. Copper concentrate is transported via two pipelines to port facilities. BHP and Microsoft have collaborated to use artificial intelligence and machine learning to improve copper recovery by optimising concentrator performance.

The mining fleet includes 14 electric rope shovels and haul trucks. The mine has begun operating exclusively with self-driving trucks in its northern pit. Drilling employs eight Bucyrus 49-R electric units and one Ingersoll Rand DMM2 diesel drill.

BHP plans significant investment in Escondida to counter the effects of declining ore grades and increased ore hardness. There is a plan to demolish the ageing Los Colorados concentrator to access high-grade ore beneath it and replace it with a new concentrator. A final investment decision for the new plant is expected around calendar year 2027-2028. The life of the existing Los Colorados plant may be extended beyond fiscal year 2027. Expansions and improvements are also planned for the Laguna Seca concentrators. BHP is also focused on new leaching technologies, such as the Full SaL project, to process minerals with high concentrations of salt and secondary sulphides. Total planned capital expenditure for BHP's Chilean operations, primarily Escondida, is between $10.7 billion and $14.7 billion over the next decade. On March 17, 2026, BHP submitted the New Escondida Concentrator project to the Environmental Impact Assessment System in Chile.

The Olympic Dam mine is a fully integrated metallurgical complex in South Australia, operating since 1988. It employs approximately 3,500 people and extracts copper, uranium, gold, and silver using sub-level open stoping underground mining and surface processing. The mine has an estimated life of 57 years based on known reserves as of 2022. BHP is investing over A$840 million in productivity enhancements and is proposing a Smelter Refinery Expansion Project to increase copper production capacity.

Production overview - 2023: copper 212000 t, gold 186000 oz.

The mine is a fully integrated metallurgical complex. The process includes a grinding and concentrating circuit, a hydrometallurgical plant with solvent extraction for copper and uranium, a copper smelter, a copper refinery, and a recovery circuit for precious metals. Ore is extracted using the sub-level open stoping underground mining method. Mined ore is transported to the surface via an automated train system and trucks using decline tunnels.

The underground operations feature more than 700 km of roads and tunnels. Recent investments are funding an expansion of the underground electric rail network from 4.85 km to over 6 km, supported by six new locomotives. A new backfill system will deliver cement paste fill via underground pipes.

BHP is investing over A$840 million in several projects to enhance productivity. This includes developing an underground decline into the Southern Mine Area to access a new part of the resource, expanding ore pass capacity, and installing a new oxygen plant to improve smelter performance. The new oxygen plant is intended to increase copper concentrate smelting rates from 80 to 85 tonnes per hour. There is a proposed Smelter Refinery Expansion Project to increase copper production capacity up to 650,000 tonnes per annum. This proposal was declared an 'impact assessed development' by the South Australian government in August 2024.

Production overview - 2023: coal 14172000 t; 2022: coal 19820201 t.

The Mt Arthur Coal Complex includes a Coal Handling and Preparation Plant (CHPP) where raw coal is crushed and washed before export. Coarse coal waste is co-disposed within overburden emplacements, and fine coal waste (tailings) is pumped to a tailings storage facility.

In June 2022, BHP announced its decision to cease mining at Mt Arthur Coal by the end of the 2030 financial year, after an attempt to sell the asset was unsuccessful. The New South Wales Government has granted approval for mining activities to continue until June 2030, extending the previous 2026 closure date. BHP is partnering with ACCIONA Energía to study the feasibility of developing a pumped hydro energy storage project at the site post-closure. Conceptual studies for the pumped hydro project suggest it could create around 1,000 jobs during construction. In November 2025, BHP announced the transfer of around 3,700 hectares of land from the Mt Arthur Coal site to the neighbouring Malabar Resources. This will allow Mt Arthur to use an existing mine void at Malabar's Maxwell Underground site for tailings storage.

The Cliffs mine, part of BHP's Nickel West operations in Western Australia, transitioned to care and maintenance in October 2024 due to nickel market oversupply and price drops. BHP plans to review the suspension by February 2027 and will invest US$300 million annually across WA Nickel assets for a potential restart. It was an underground nickel sulphide operation.

Nickel sulphide ore extracted from the mine was transported by road to BHP's Leinster Nickel Operation for processing in a concentrator and dryer.

around 1,000 people

Production overview - 2004: nickel 44577 t.

Ore from the Leinster mines is processed at a concentrator and dryer located at Leinster. The Leinster concentrator has the capacity to handle three million tonnes of ore annually. The resulting nickel concentrate is then transported by rail to the Kalgoorlie Nickel Smelter for further processing.

A major recent development was the B11 block cave, which became fully operational in October 2023 and was expected to contribute up to 50% of the ore production at Leinster. This project was planned to recover over 80,000 tonnes of nickel.

The suspension of BHP's Western Australia Nickel operations was expected to affect approximately 1,600 frontline employees across all sites. As of October 2024, redeployment offers had been made to over 700 people across Nickel West.

BHP announced on 11 July 2024 that it would temporarily suspend its Western Australia Nickel operations, including Mount Keith, from October 2024. The site entered care and maintenance in December 2024, with a review of the suspension scheduled for February 2027. The decision was due to an oversupply in the global nickel market.

Production overview - 2023: nickel 165500 t; 2022: nickel 195800 t.

Disseminated sulphide ore is mined from the open-pit operation and the Mount Keith Satellite mine (Yakabindie). The ore is crushed and processed on-site at a concentrator to produce nickel concentrate. The process involves conventional crushing, semi-autogenous grinding (SAG) and ball milling, separation, flotation, and thickening and recovery. The nickel concentrate is then transported by road to the Leinster operations for drying before being sent to the Kalgoorlie Nickel Smelter.

The mining fleet includes hydraulic excavators, rope shovels, and haul trucks such as the Caterpillar 793 model. A 2021 expansion plan included adding Liebherr 9600 and 9400 excavators.
