    Epiroc Bio thread grease: performance and compliance notes for hard rock mines

    October 16, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Epiroc has launched Epiroc Bio thread grease, a biodegradable, high-performance thread lubricant for demanding rock drilling applications on rigs and underground production equipment. The grease is formulated to protect drill string threads and shank adapters under high contact pressures and vibration, while maintaining film strength in wet, abrasive conditions typical of hard rock operations. Verified sustainability credentials are aimed at mines seeking to cut petroleum-based lubricants in sensitive environments and simplify compliance with stricter site discharge and waste-handling rules.

    Technical Brief

    • For multi-jurisdiction operators, a single biodegradable grease specification can simplify lubricant standardisation across sites.

    Our Take

    Epiroc’s recent product roll-out cadence in our database – from the ET55 drill string (October 2026) to automation upgrades for Pit Viper rigs and underground haulage – suggests this new bio thread grease is part of a broader strategy to lock customers into an integrated, OEM-specified drilling ecosystem.

    With Epiroc equipment now deeply embedded in large copper and platinum operations such as Sibanye-Stillwater’s Rustenburg complex, verified-sustainable consumables like bio-based greases are likely to help mine operators document Scope 3 reductions and ESG compliance along OEM supply chains.

    Minnova’s C$76M PL gold mine restart: economics and strip risks for engineers

    Minnova plans a C$76.2 million restart of the brownfield PL gold mine near Sherridon, Manitoba, targeting 62,200 oz per year over 10 years from a high‑grade open pit feeding an existing 1,000 t/d plant, which is slated to double to 2,000 t/d in year two. The September resource stands at 3.76 million measured and indicated tonnes at 4.98 g/t Au (601,158 oz) plus 1.67 million inferred tonnes at 3.78 g/t (202,810 oz), with open pits carrying a high 21:1 waste‑to‑ore strip ratio. At US$3,000/oz gold, the PEA projects an after‑tax NPV5 of US$180.6 million, 111% IRR, eight‑month payback and all‑in sustaining costs of US$2,288/oz, but value falls sharply at lower prices, underlining cost and strip sensitivity.

    Caterpillar Resource Industries leadership shift: fleet and autonomy cues for miners

    Caterpillar has confirmed that Denise Johnson, Group President of Resource Industries since 2016 and a key figure in expanding autonomous haulage and large mining truck platforms, will retire on 1 February 2027. Derrick York, currently President of Solar Turbines and a Caterpillar Senior Vice President overseeing industrial gas turbines and compressor sets, will become Group President of Resource Industries on 1 November 2026, with Johnson shifting to an advisory role. The handover timetable gives miners nearly a year of overlap to align major fleet, autonomy and support contracts with the incoming leadership.

    Anglo American copper scarcity and tech tie-ups: key takeaways for mine planners

    Tech companies are in talks to buy equity in Anglo American to secure long-term copper and other data centre metals, as Comex copper trades near $6.52/lb and LME cash copper recently hit a record $14,822/t. Anglo’s planned merger with Teck Resources would create a roughly $90 billion group producing about 1.2 million tonnes of copper per year, controlling around 5% of global supply, but is still awaiting Chinese antitrust clearance tied to concentrate flows to local smelters. Wanblad also warned Anglo may close its Brazilian nickel operations at Codemin and Barro Alto if the EU blocks the $500 million sale to MMG despite proposed long-term European ferronickel supply commitments.
