    Worsening wildfire seasons for mine operators: design and continuity lessons

    Worsening wildfire seasons for mine operators: design and continuity lessons

    First reported on MINING.com

    30 Second Briefing

    Wildfire seasons in Western Canada are intensifying, with 2023 seeing more than 2,240 fires burning 2.84 million hectares in B.C. and insured losses of $720 million in the Okanagan/Shuswap and $1.3 billion from the 2024 Jasper fire, forcing repeated evacuations at sites such as Artemis Gold’s Blackwater and Cameco’s Cigar Lake. Operators and insurers are now treating wildfire as a core business-interruption risk, driving investment in backup generation for long transmission corridors, detailed continuity planning, and stricter underwriting. Engineers are also redesigning mine layouts and buildings for fire, favouring sites on ridge tops, wider building separation, non-combustible steel roofing and use of natural and linear infrastructure firebreaks.

    Technical Brief

    • BC Wildfire Service flags Chilcotin, Cariboo and Thompson-Okanagan as priority risk regions.
    • Teck’s Highland Valley Copper previously shut under an evacuation order due to wildfire risk.
    • Artemis Gold’s Blackwater and Osisko Development’s Cariboo Gold both removed non-essential staff under regional wildfire evacuation directives.
    • Cameco’s Cigar Lake uranium mine in northern Saskatchewan evacuated non-essential personnel due to wildfires.
    • Long transmission lines to remote mines are identified as critical single points of failure during wildfires.
    • BC Hydro mitigations include fire-retardant or fire-resistant steel-mesh wraps with heat-activated barriers on poles.
    • Guidance advises siting facilities away from slopes and using simple, non-combustible steel roofs.
    • Vegetation management around high-energy equipment during the driest periods is being scheduled using short-term fire probability forecasts.
    • Climate-adaptation guidance and 30‑year climate-normal tools are informing mine infrastructure risk assessments.

    Our Take

    With British Columbia already prominent in our 39 Hazards stories, the wildfire exposure around assets like Highland Valley Copper and Blackwater sits on top of a parallel layer of legal and permitting uncertainty flagged in our DRIPA coverage for projects such as Record Ridge.

    The scale of 2023–24 insured wildfire losses in the Okanagan, Shuswap and Jasper regions suggests operators like Teck Resources and Artemis Gold may soon face materially tighter insurance terms and higher premiums for coal, copper and gold assets in Western Canada, pushing more cost–benefit scrutiny on on-site fire-hardening investments.

    Guidance on climate adaptation for mine infrastructure dating from 2020 now predates the extreme 2.84-million-hectare burn in B.C., implying that companies such as Cameco and Osisko Development may need to revisit design criteria for power, evacuation and tailings systems to reflect a higher baseline of fire frequency and smoke disruption risk.

    Acorn adds commercial manager: implications for asbestos project delivery and safety

    Asbestos management consultancy Acorn Analytical Services has appointed Ben James as commercial manager to lead its sales team and secure larger, more complex consultancy and removal projects. James, a former apprentice carpenter and joiner, moved into asbestos work in his early twenties after his grandfather died from asbestosis and has since progressed from trainee asbestos surveyor to contract manager over nine years. He will oversee new technical enquiries, key account management and site visits, and is qualified to deliver asbestos awareness, non-licensed removal and duty-to-manage training under a Level 3 teaching qualification.

    Coalsnaughton mine subsidence demolitions: geotechnical lessons for engineers

    Homes on Benbuck View and Dunmoss View in Coalsnaughton, Clackmannanshire are to be demolished after Mining Remediation Authority investigations confirmed historic underground workings had caused active mine subsidence beneath the two streets. The decision follows visible ground movement reported on 18 May and subsequent detailed geotechnical assessments that ruled out practical stabilisation options for the affected plots. Engineers will now need to manage demolition, backfilling and long-term ground monitoring, with implications for foundations and service corridors on adjacent properties built over former coal measures.

    LondonEnergy Wembley Waste Transfer Station fire: structural and fire design lessons

    A major fire at LondonEnergy’s Wembley Waste Transfer Station on Hannah Close, Neasden, has required 20 fire engines and about 125 firefighters to bring the blaze under control. The incident at the enclosed waste-handling facility raises immediate concerns over structural integrity of steel frames, cladding performance under high thermal loads, and potential damage to concrete slabs from prolonged heating and quenching. Engineers will need rapid assessment of fire spread pathways through waste stockpiles and building services to inform repairs, resilience upgrades and future fire-separation design.
