ArcelorMittal Exploitation Minière Canada has been fined C$100 million, the largest penalty ever under Canada’s Fisheries Act, after pleading guilty to 100 counts for discharging low‑pH effluents and waters with elevated zinc, nickel and suspended solids from its Mont‑Wright and Fire Lake iron ore operations between 2014 and 2022. Nearly C$250,000 in investigation costs must also be repaid, and a detailed effluent and mine drainage management plan for both complexes is due to federal enforcement officers by mid‑February 2027. The company says it has since invested over C$400 million in permanent water control and treatment infrastructure.

Arca Technologies has secured up to C$2 million from NRC IRAP’s Clean Tech initiative towards a C$7.4 million project to move its mineral activation and engineered carbonation processes from lab to field scale, targeting alkaline wastes such as mine tailings and steel slag. The company will design containerised, field‑deployable mineralisation units and prepare a first‑of‑kind industrial pilot, billed as the first field‑scale system to accelerate carbon mineralisation in mine waste. Commercial traction includes a 10‑year offtake with Microsoft for nearly 300,000 tonnes of CO₂ removal and an early pre‑purchase from Frontier.

Jacobs has been appointed by Great British Energy – Nuclear to deliver environmental consultancy and baselining at the Oldbury site in Gloucestershire, earmarked as a potential location for a new nuclear power station. The work will characterise existing ground, groundwater, ecological and radiological conditions to support future nuclear site licensing, environmental permits and design optioneering. Early baselining data will be critical for later geotechnical investigations, foundation design, flood and coastal risk assessments, and long-term monitoring strategies if the project proceeds.
