    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.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.

    Silver price 20% August surge: leverage, scenarios and risks for mine planners

    Silver surged about 20% in August to touch $70/oz on 21 August, driven by the US Treasury’s move to double long-bond buybacks, pushing prices above several banks’ 2026 baseline forecasts but still below the most bullish $110–$160/oz year-end and Q4 targets. Equity leverage has been stark: Hecla Mining gained 47%, Wheaton Precious Metals 44%, and Coeur, First Majestic and Fortuna each 42%, while the Global X Silver Miners ETF rose 35% and junior-focused SILJ 32%. Forecasts now span roughly $67–$118/oz for peaks, with tail-risk scenarios from Bank of America and BMO stretching above $135/oz if the gold–silver ratio compresses.
