BHP Group announced it will sell its Kambalda nickel concentrator plant and the surrounding land in Western Australia to Gold Fields, with the price not disclosed, according to a BHP statement on Wednesday.
The transaction includes the mining tenements and mineral rights that sit on the site. A nickel concentrator is a processing facility that upgrades raw ore by increasing its nickel content before further refining.
The Kambalda mill was shut in mid-2024 after BHP halted operations across its Nickel West business when global nickel prices plunged on an oversupply of the metal. BHP recorded a $2.5bn impairment (an accounting loss that writes down the value of an asset) on its nickel assets in 2024 after a surge in supply from Indonesia pushed prices down.
BHP said it continues to review the remainder of its Nickel West portfolio, a refinery, a smelter and two major mines, and expects a decision on their future by February.
For Gold Fields, the purchase fits a broader strategy of acquiring mining infrastructure in the region. The company is also considering a second takeover bid for Northern Star Resources, which holds several gold projects near Kambalda, suggesting it may explore restarting or repurposing the concentrator.
Local contractors and workers could see new activity if Gold Fields decides to bring the plant back online, potentially boosting the regional economy. South African investors will be watching how the deal influences Gold Fields’ balance sheet and share performance.

Gold Fields will “evaluate options for the long-term use of the concentrator,” BHP said in its Wednesday statement, meaning the new owner can decide whether to restart nickel processing, convert the plant for another mineral or dismantle it for parts. The undisclosed purchase price leaves the financial impact to be assessed once the transaction closes, while the inclusion of the surrounding land gives Gold Fields flexibility to develop ancillary facilities or expand the site footprint in line with its regional growth plans.
The transaction bundles the Kambalda mining tenements and the associated mineral rights, a combination that transfers both surface and subsurface control to Gold Fields. Such bundled assets typically require the Western Australian Department of Mines to endorse the change of ownership, after which the new holder must lodge the updated titles with the state land registry. This procedural step ensures that the legal entitlement to extract ore and to operate the processing plant passes cleanly from BHP to its buyer.
Because the Kambalda mill was shut in mid-2024 when BHP halted operations across its entire Nickel West portfolio, the plant has been idle for several months. The shutdown followed a sharp decline in nickel prices driven by an oversupply, a market condition that also forced BHP to record a $2.5 billion impairment on its nickel assets in 2024. The idle status means that any restart will require a fresh capital allocation for maintenance, staffing and possibly upgrades to meet current environmental standards.
BHP’s broader review of its Nickel West assets, which includes a refinery, a smelter and two major mines, is slated for a decision by February. This timeline suggests that the company will have a clearer picture of its remaining portfolio before finalising any further disposals or reinvestments. The February deadline also aligns with the end of the fiscal quarter, a period when large miners often lock in strategic moves to reflect on year-end performance.
Gold Fields’ interest in acquiring infrastructure near Kambalda dovetails with its parallel consideration of a second takeover bid for Northern Star Resources, which holds several gold projects in the vicinity. By securing the concentrator, Gold Fields could potentially create a shared services hub that supports both nickel and gold operations, leveraging existing processing capacity to reduce the need for separate facilities and to achieve economies of scale across its expanding asset base.
Once the sale agreement is signed, the parties will enter a due-diligence phase where technical audits of the plant’s condition, environmental compliance checks and verification of the mineral rights are completed. After satisfactory completion, the transaction will move to a settlement stage, at which point ownership of the physical plant, land and tenements will be transferred, and Gold Fields will assume responsibility for any outstanding liabilities tied to the site.
