    Red Chris mine expansion funding: design, emissions and output lens for engineers

    Red Chris mine expansion funding: design, emissions and output lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Canada has committed C$500 million ($352 million) to Newmont’s Red Chris Block Cave expansion in British Columbia’s Golden Triangle, backing the transition from open-pit to underground block caving and extending mine life into the mid-2040s. The project targets a porphyry resource of roughly 20 million oz gold and 13 billion lb copper, with the government projecting more than a 15% increase in Canada’s annual copper output and over 70% reduction in site greenhouse gas emissions once fully operational. Newmont, which operates Red Chris with 30% JV partner Imperial Metals, is finalising a definitive feasibility study and anticipates around 1,800 construction jobs and 1,500 peak operational roles.

    Technical Brief

    • Federal C$500 million support is explicitly tied to the Red Chris Block Cave expansion phase.
    • Government statement links funding to fast-tracking major mining projects through Canada’s approvals and financing pipeline.
    • Red Chris porphyry resource base quoted at 20 Moz Au and 13 billion lb Cu (all categories).
    • Ownership structure: Newmont as operator and majority owner, Imperial Metals retaining a 30% JV stake.
    • Key regulatory approvals for the underground transition were secured “last month”, enabling detailed execution planning.
    • Newmont is still finalising a definitive feasibility study prior to making a formal final investment decision.
    • Construction workforce is forecast at >1,800 jobs, with about 1,500 roles at peak seasonal operations.
    • Government messaging explicitly links Red Chris output to critical minerals supply for clean energy and manufacturing sectors.

    Our Take

    With Red Chris resources of about 13 billion lb copper and 20 million oz gold and Imperial Metals holding a 30% joint-venture stake, this expansion materially underpins Imperial’s asset base and gives Newmont a Canadian copper anchor that complements its Australian Cadia block cave operations referenced in our 19 June 2026 coverage.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
