    Rockwell–Mimosa Mine cybersecurity upgrade: control system lessons for engineers

    September 2, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Rockwell Automation has partnered with Mimosa Mine and local integrator Mine Elect to upgrade operational technology cybersecurity as part of a multi‑year digital migration at the platinum‑group metals and base metals operation in Zimbabwe’s Midlands Province. The collaboration focuses on securing industrial control systems and networked assets as Mimosa modernises plant automation, data acquisition and remote monitoring. For engineers, the move signals tighter integration of cybersecurity with process control upgrades, with implications for risk assessments, network segmentation and lifecycle management of legacy OT hardware.

    Technical Brief

    • Cybersecurity is being embedded into Mimosa’s existing process safety and risk management frameworks, not treated as standalone.
    • Similar brownfield mines with ageing PLC/SCADA fleets face comparable retrofit challenges integrating security without production downtime.

    Our Take

    PGM operations like Mimosa Mine in Zimbabwe tend to run highly automated concentrators and smelter interfaces, so adding Rockwell Automation cybersecurity hardening likely targets process control and remote access pathways that, if compromised, could halt high‑value continuous production.

    Within our 1286 Mining stories, only several keyword‑matched pieces focus on platinum‑group metals, suggesting that detailed coverage of digital and safety upgrades at PGM sites in regions such as Zimbabwe’s Midlands Province remains relatively sparse compared with gold and bulk commodities.

    For a mature PGM asset in Zimbabwe, enhanced OT cybersecurity can be a low‑capex way to protect against unplanned downtime and regulatory scrutiny, which is increasingly important as base‑metal by‑product credits and tight margins make even short outages more financially visible.

    Greenland Resources’ $120M NIB backing: Malmbjerg project economics for mine planners

    Greenland Resources has secured a letter of interest from the Nordic Investment Bank for up to $120 million in export credit agency-backed funding for its Malmbjerg molybdenum project in east-central Greenland, adding to an Export Development Canada expression of interest of up to $275 million. The project, covered by a 30-year exploitation licence within a 1,147 km² land package, has NI 43-101 proven and probable reserves of 245 million tonnes at 0.176% MoS₂, containing 571 million lb of molybdenum. Planned output in years one to ten is 32.8 million lb/y of contained molybdenum metal at 0.23% MoS₂, equivalent to roughly a quarter of EU annual consumption and all EU defence demand.

    Collective’s Apollo extension in Colombia: bulk-mining and resource lens for engineers

    Collective Mining has extended the Apollo system at its Guayabales project in Colombia by about 100 metres north after drill hole APC172-D2 cut 141.4 metres grading 4.75 g/t gold, 5 g/t silver, 0.02% copper and 0.04% zinc from ~924 metres depth, including 38 metres at 15.25 g/t gold and 8 g/t silver. The new breccia body, intersected roughly 1,000 metres below surface and about 170 metres below previous northern drilling, lies close to a planned underground access tunnel, supporting potential bulk-mining scenarios. Thirteen rigs are active at Guayabales in a programme of up to 90,000 metres this year, with Apollo’s initial resource estimate due this month.

    Gold price erases 2026 gains: risk and valuation notes for mine planners

    Gold fell for a third straight session on Tuesday, with Comex December futures down as much as 2.4% to $4,374.10/oz and spot at $4,362.57/oz, as Fed hike odds for this month climbed to nearly 70% and 10-year US Treasury yields held near 4.77% alongside UK gilts at 5.22%. Silver dropped up to 3.2% to $64.83/oz, tightening the gold–silver ratio to about 67 from 70 at end-July. Despite bullion now only 0.7% higher in 2026, the NYSE Arca Gold Miners Index surged 33% in August, with Eldorado up 44% and Equinox 40%, signalling continued equity leverage to metal price swings.
