New research from Sandvik’s global engineering group points to a shrinking pipeline of mining engineers, with survey data showing young professionals rank decarbonisation projects, automation and digital systems above traditional pit or plant roles. Respondents cited reluctance to work FIFO rosters and in remote camps, and a preference for hybrid city-based roles linked to remote operations centres and OEM technology hubs. Sandvik argues miners must redesign graduate pathways around battery-electric fleets, data analytics and equipment condition monitoring to compete with infrastructure, renewables and tech employers.

Rio Tinto and Viva Energy have completed a large-scale renewable diesel trial, showing haul trucks and other heavy mobile equipment can switch from conventional diesel with no changes to engines, fuel systems or maintenance schedules. The trial used drop-in hydrotreated vegetable oil (HVO)-type fuel in standard high-horsepower mining fleets, validating cold-start performance, fuel consumption and engine wear against OEM limits. Results indicate sites with existing diesel storage and distribution can cut Scope 1 emissions from mobile equipment rapidly by substituting fuel rather than retrofitting fleets.

Global bauxite production is forecast to grow in 2025, but analysts warn that political instability and recent export disruptions in Guinea – which supplies more than a quarter of seaborne bauxite – could tighten alumina refineries’ feedstock security. Australia, producing around 100Mtpa from large open‑cut operations in Queensland and the Northern Territory, is expected to provide stable output and shipping, with no major greenfield capacity changes flagged. Any prolonged Guinean constraint would likely redirect Chinese and Middle Eastern offtake towards Australian and Indonesian ore, affecting contract terms and freight dynamics.
