    Rio Tinto renewable diesel trial: HVO fleet switch insights for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    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.

    Technical Brief

    • For other large mining fleets, the trial provides operational data to support regulatory approvals and internal decarbonisation roadmaps.

    Our Take

    Within our 52 Mining stories, Rio Tinto appears frequently in decarbonisation and fuel-switching pieces, signalling that trials like this renewable diesel work in Australia are moving from one-off pilots towards a portfolio-level transition strategy.

    Australia-focused Sustainability-tagged items in our database increasingly involve collaboration with domestic energy suppliers, so Rio Tinto’s work with Viva Energy fits a pattern where miners test low-carbon fuels through local downstream partners rather than importing solutions.

    For heavy mobile and rail equipment in Australian mining, renewable diesel is one of the few near-term drop-in options that does not require wholesale fleet replacement, so successful trials by a major like Rio Tinto could lower perceived technology risk for smaller operators considering similar moves.

    Sunshine’s Sybil gold system: drilling expansion and geometry notes for mine planners

    Sunshine Metals has expanded the Sybil gold system in north Queensland, reporting a standout reverse-circulation intercept of 4m at 11.11g/t gold from 62m at Francis Creek within a 66-hole, 4357m drilling campaign. First-pass drilling at Francis Creek East intersected shallow mineralisation, confirming gold continuity east of the main trend and extending the project’s near-surface footprint. The results support follow-up RC and potential diamond drilling to refine geometry, test depth extensions and upgrade exploration targets to resource status.

    WAM Australia mine-site bulk handling: design and dust-control notes for engineers

    WAM Australia is promoting enclosed bulk-handling solutions for mine transfer points using CAO tubular screw feeders and VFS butterfly valves to manage dust, variable flow rates and abrasive ores in tight layouts. The compact tubular screws provide controlled, fully enclosed transfer over short to medium distances, reducing spillage and dust emissions compared with open belts or chutes. Low-maintenance designs with minimal external bearings and sealed housings target reduced downtime in high-duty applications such as crusher feed, mill discharge and load-out spurs.

    Asset life extension in a capital-disciplined market: lessons for mine asset teams

    Ageing port, plant and rail assets are emerging as a major value lever for Australian miners, with projects such as BHP’s Berth C&D structural remediation showing owners favour targeted renewal of critical wharf infrastructure over full replacement. Capital is being steered towards brownfield opportunities and life-extension works that keep existing load‑out, materials handling and processing circuits operating reliably under tighter cost and capital constraints. For geotechnical and structural teams, this means more condition assessment, strengthening and corrosion remediation on live assets rather than designing greenfield builds.
