    BQE Water Kemess restart: selenium treatment and permitting insights for engineers

    July 15, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    BQE Water and Centerra Gold have begun preparations to restart the selenium treatment plant at the Kemess copper-gold project in northern British Columbia, originally built and briefly operated in 2020 to manage mine-impacted water. The plant is designed to remove selenium from contact water before discharge, using BQE’s specialised process technology to meet stringent provincial water quality limits. Restarting the facility signals advancing project development and will be central to permitting and long-term water management planning for any future underground or open pit operations.

    Technical Brief

    • Plant re-start is tied to development of a new copper-gold mine at Kemess.
    • Facility was originally commissioned and operated briefly in 2020, so restart involves recommissioning rather than greenfield build.
    • Experience from the 2020 operating period will inform optimisation of start-up, control logic and reagent management.

    Our Take

    Kemess adds to a relatively small subset of our 1242 Mining stories where selenium is explicitly flagged alongside copper and gold, signalling that selenium discharge limits are now a design driver rather than a secondary compliance issue for Canadian projects.

    BQE Water Inc’s involvement at Kemess aligns with a cluster of items in our coverage where specialist water operators are retained on long-term service models, suggesting that mid-tier miners increasingly outsource complex selenium and metal-removal circuits instead of owning that process expertise in-house.

    Vitreo’s $300M Angus silica sand mine: EAO approval and design notes for engineers

    British Columbia has issued an environmental assessment certificate for Vitreo Minerals’ $300 million Angus silica sand mine north of Prince George, clearing the way for a 20‑year operation producing up to 2 million tonnes of proppant annually. The Environmental Assessment Office found no significant adverse effects with mitigation, and requires the project to be substantially started by 2036. Construction is expected to create about 150 jobs and operations nearly 140, with formal participation from Lheidli T’enneh, McLeod Lake, Tsay Keh Dene and West Moberly First Nations in the assessment process.

    Macmahon at Mt Marion: underground shift and design notes for lithium mine teams

    Macmahon Underground Pty Ltd has secured an underground mining services contract at the Mt Marion lithium operation, 70 km south of Kalgoorlie, jointly owned by Mineral Resources and Jiangxi Ganfeng Lithium on a 50:50 basis. The scope covers underground development and production work, signalling a shift from Mt Marion’s historically open-pit focus towards a deeper, longer-life operation. Geotechnical and mine planning teams should expect new requirements around underground ground control, ventilation, and ore handling design for hard-rock lithium orebodies in the Eastern Goldfields setting.

    Almonty–Global Tungsten offtake extension: supply and pricing lens for mine planners

    Almonty Industries has extended its offtake agreement with Global Tungsten & Powders for concentrate from the Sangdong mine in South Korea from 15 to 21 years, lifting total contracted volume by 40% from 3,150,000 to 4,410,000 metric tonne units and locking in a 6.3% price uplift per MTU. The deal secures minimum deliveries of 210,000 MTU per year after ramp-up, covering about 90% of Phase I mine output and supplying GTP’s US facilities. With Chinese export curbs driving record tungsten prices, the contract provides long-duration, conflict-free feedstock into Western defence and industrial powder supply chains.
