    Sandvik IEC 62443-4-1 ML3: cybersecurity implications for intelligent mines

    Sandvik IEC 62443-4-1 ML3: cybersecurity implications for intelligent mines

    First reported on International Mining – News

    30 Second Briefing

    Sandvik has secured IEC 62443-4-1 Maturity Level 3 certification for its secure product development lifecycle, making it one of the first mining OEMs to reach this cybersecurity benchmark. The independently audited ML3 rating confirms that threat modelling, secure coding, vulnerability management and patch processes are systematically built into the design and maintenance of its intelligent mining equipment and digital systems. For mines deploying connected fleets, autonomous loaders and remote drilling rigs, this signals stronger protection against cyber intrusion at both equipment and control-system level.

    Technical Brief

    • IEC 62443-4-1 ML3 requires defined, measured and continuously improved secure-development processes across product lifecycles.
    • Independent auditing under IEC 62443-4-1 verifies evidence of repeatable security practices, not self-declared compliance.
    • Secure-development requirements extend to maintenance phases, including structured handling of discovered vulnerabilities over product life.

    Our Take

    Within our mining safety-tagged coverage, very few equipment OEM stories reference a defined cybersecurity maturity level, so Sandvik’s disclosure here signals to operators that cyber assurance is becoming a differentiator alongside traditional mechanical reliability.

    For customers visiting Sandvik’s Turku and Tampere facilities during the Future of Mining 2026 events, a Level 3 secure development process means any demonstrations of connected trucks, drills and AI-driven systems are more likely to align with emerging site-level requirements for secure OT networks and remote operations centres.

    EPC Groupe–Sabodala contract: blasting capacity and slope control insights for engineers

    EPC Groupe, through EPC Mineex Sénégal, has secured a five-year explosives supply and services contract with Endeavour’s Sabodala gold mine in Senegal, valued at about €10 million per year at full run rate. The deal covers bulk explosives and blasting support for one of West Africa’s largest open-pit gold operations, signalling a step-up in local emulsion manufacturing, on-bench services and blast design capability. For mine planners and geotechnical teams, the contract points to stable high-volume blasting capacity, supporting consistent fragmentation and slope performance over the medium term.

    Haultrax HX Coach in FMS: operational coaching and dispatch insights for mine teams

    Haultrax is integrating its on-site operational coaching directly into its Fleet Management System with the launch of HX Coach at IMARC 2026. The module is designed to embed real-time operator guidance and training logic into haulage fleet dispatch, moving beyond traditional FMS reporting towards in-cab behavioural feedback and decision support. For mine operators, this signals a shift from separate coaching programmes to a software-native approach that can systematically influence truck and shovel performance at scale.

    IsaMill at 30: fine grinding efficiency lessons for concentrator engineers

    Glencore Technology is marking 30 years of the IsaMill fine grinding mill, first developed by Mount Isa Mines and NETZSCH to tackle complex, ultra-fine regrind duties in base metal circuits. The horizontal, high-intensity stirred mill has since been deployed in more than 130 installations globally, often replacing ball mills in the sub-20 µm range to cut specific energy consumption and increase throughput. Recent IsaMill developments focus on larger M-series units, improved ceramic media wear performance and integration with modern flotation and coarse particle recovery flowsheets.
