Minerals Australia Briefing

BHP Minerals Australia President, Mike Henry, today outlined plans to grow value and improve returns on capital across the Company’s Australian operations.

Speaking to investors and analysts at a briefing in Adelaide, Mr Henry said BHP’s large, long-life, low-cost Australian assets underpin current margins and future optionality.

“The quality, scale, concentration and location of our assets support improvement initiatives, compelling latent capacity options, efficient technology deployment and attractive investment opportunities.

“By sharing knowledge and replicating best practice across our global portfolio, we’ve been able to substantially reduce unit costs at our Australian mining operations over the last five years. But we have further to go. We can make ourselves safer and even more productive, and expect to lower our unit costs by a further 10 per cent over the medium-term.

“Through strengthening our maintenance capability and processes, including by bringing in expertise from other industries, and through better leveraging technology, our global Maintenance Centre of Excellence is enabling a step-change in maintenance performance across BHP. With our global technology initiatives and asset-level programs to unlock resources and lower costs, we expect our Australian mining operations to deliver US$1.6 billion of additional productivity gains over the next two years,” Mr Henry said.

“We also have a suite of attractive medium-term investment opportunities. While these remain subject to our strict Group-level capital allocation framework tests, with average returns potentially exceeding 40 per cent, they are well placed to compete for capital.”

Mr Henry highlighted the Brownfield Expansion option (BFX) at Olympic Dam as an example of a project with the potential to deliver sustainable returns to shareholders, government and the local community.

Also speaking at the briefing, Olympic Dam Asset President Jacqui McGill, said the BFX option could provide a capital efficient path to increased capacity through accelerated development into the Southern Mine Area.

“As we move into the Southern Mine Area we expect to see the copper grade increase to 3 per cent by financial year 2023, which we believe would coincide with a structural deficit in the copper market.

“If approved, the BFX option could lift production capacity to 330 ktpa and move Olympic Dam into the first quartile of the cost curve, which is where we strive to be with all our assets at BHP. Any investment however, must compete for capital against all other options, including returns to shareholders.”

Ms McGill also outlined longer-term development options that had the potential to significantly increase the volume of copper produced, including the use of heap leach technology.

Combined, these plans create significant value and support improved returns both at Olympic Dam and across BHP’s minerals operations in Australia.

WAIO: Asset snapshot Overview of asset Western Australia Iron Ore (WAIO) is an integrated system of four processing hubs and five mines, connected by more than 1,000 kilometres of rail infrastructure and port facilities in the Pilbara region of northern Western Australia. At each mining hub – Newman, Yandi, Mining Area C and Jimblebar – ore from mines is crushed, beneficiated (where necessary) and blended to create high-grade hematite lump and fines products. Iron ore products are then transported along the Port Hedland – Newman Rail Line to the Finucane Island and Nelson Point port facilities at Port Hedland. WAIO’s port facilities at Nelson Point are owned by the Mt Newman JV, and Finucane Island is owned by the Mt Goldsworthy JV. BHP interest varies between 85 and 100% across joint ventures.

Nickel West: Asset snapshot Overview of asset Nickel West is a fully integrated mine-to-market nickel business. All nickel operations (mines, concentrators, a smelter and refinery) are located in Western Australia. The integrated business adds value throughout our nickel supply chain, with the majority of Nickel West’s production sold as powder and briquettes. Low-grade disseminated sulphide ore is mined from Mt Keith, a large open-pit operation. The ore is crushed and processed on-site to produce nickel concentrate. High-grade nickel sulphide ore is mined at Cliffs and Leinster underground mines and Rocky’s Reward open-pit mine. The ore is processed through a concentrator and dryer at Leinster. Nickel West’s concentrator plant in Kambalda processes ore and concentrate purchased from third parties. The three streams of nickel concentrate come together at the Nickel West Kalgoorlie smelter, a vital part of our integrated business. The smelter uses a flash furnace to smelt more than 700 ktpa of concentrate to produce nickel matte. Nickel West Kwinana then refines granulated nickel matte from the Kalgoorlie smelter into nickel powder and premium-grade nickel metal briquettes containing over 99 per cent nickel. Nickel matte and metal are exported to overseas markets via the Port of Fremantle.
