    Ottawa’s C$500M Red Chris bet: grid, queueing and power costs for mine planners

    Ottawa’s C$500M Red Chris bet: grid, queueing and power costs for mine planners

    First reported on MINING.com

    30 Second Briefing

    Ottawa’s C$500 million backing for Newmont’s Red Chris Block Cave, tied to a wider C$3.9 billion Canada–BC package for BC Hydro’s North Coast Transmission Line, is turning northern BC’s constrained grid into the key gatekeeper for new copper, gold and LNG projects. Red Chris alone will need up to 145 MW from Northwest Transmission Line upgrades, while Seabridge’s KSM is modelling about 245 MW and Skeena’s Eskay Creek 38–39 MW at roughly C$0.06/kWh versus diesel at about C$0.25/kWh. With the first 165 km Williston–Glenannan segment coming online and the Prince George–Terrace capacitor project already fully subscribed, mine developers’ sequencing in BC Hydro’s transmission queue now directly drives power strategy, permitting risk and project economics.

    Technical Brief

    • BC Hydro’s first 165 km North Coast segment links Williston (near Prince George) to Glenannan substation.
    • Ottawa’s conditional C$44.2M funding targets Northwest Transmission Line upgrades, including up to 25 MW for KSM construction.
    • BC Hydro’s Prince George–Terrace capacitor project, due fully in 2028, is already fully subscribed for capacity.
    • North Coast plan twins the 500‑kV Prince George–Terrace system by fall 2030 and mid‑2032 in two stages.
    • Treaty Creek Terminal switching station, targeted in service fall 2026, will connect KSM via a 30‑km 287‑kV spur.
    • Existing 344‑km, 287‑kV Northwest Transmission Line from Terrace to Bob Quinn has limited spare capacity north of Terrace.
    • Teck’s Schaft Creek concept requires a private 95‑km, 287‑kV line to Bob Quinn substation for grid access.
    • Kutcho Copper’s remote copper‑zinc project east of Dease Lake still hinges on identifying a viable power solution.
    • Queue‑based transmission allocation means filing date for service requests now materially structures mine development sequencing.

    Our Take

    Across our mining-projects coverage, few copper–gold developments in Canada combine this scale of federal backing with such long-dated grid milestones, signalling that northwestern BC’s permitting and power build-out sequence could become a de facto pacing mechanism for the region’s broader critical-minerals pipeline, including molybdenum and zinc prospects tied into the same corridor.

    Techking–Boonray autonomous mining tyres: design and duty-cycle notes for engineers

    Techking is collaborating with Chinese autonomous haulage specialist Boonray to co-develop mining truck tyres tailored to electric and driverless fleets, where high, instantaneous torque and tighter speed control change loading behaviour. The partners are integrating tyre design into early vehicle engineering, using Boonray’s AHS control data on torque curves, duty cycles and haul-road conditions to refine carcass structure, compound selection and heat management. For mine operators, this points to tyre performance being tuned to specific autonomous truck–road systems rather than generic TKPH-based selection.

    EcoPower Mate temporary power: layout and staging insights for mine planners

    EcoPower Mate introduces a modular temporary power system for remote mines, targeting exploration camps, mobile offices, communications nodes and construction facilities that currently rely on diesel gensets. Designed for locations with shifting footprints and variable loads, the units can be redeployed as drilling pads, laydown areas or satellite camps move, reducing the need to oversize fixed generator banks. For mine planners and project engineers, the approach supports more flexible power layouts and staged infrastructure without committing to early grid extensions.

    Sedgman wins Barroso lithium FEED: design and risk notes for project engineers

    Sedgman has secured the Front-End Engineering and Design contract for the lithium concentrator plant at Savannah Resources’ Barroso lithium project in northern Portugal, following its earlier work on the process flowsheet and Definitive Feasibility Study plant design. The FEED scope will refine equipment selection, layout and mass–energy balances for the hard-rock spodumene concentrator, de-risking capital estimates ahead of a final investment decision. For geotechnical and civil teams, the move signals progression towards detailed earthworks, foundations and tailings/waste infrastructure design on what is billed as mainland Europe’s largest lithium project.
