    Blue Moon’s 13‑year Nussir copper mine: economics and schedule for engineers

    Blue Moon’s 13‑year Nussir copper mine: economics and schedule for engineers

    First reported on MINING.com

    30 Second Briefing

    Blue Moon Metals’ updated feasibility study for the Nussir copper project in northern Norway outlines a 13‑year underground operation producing an average 19,000 tonnes CuEq per year, including 3,600 oz gold and 546,000 oz silver, from measured and indicated resources of 28.72 million tonnes at 1.2% CuEq. The base case gives an after‑tax NPV8 of $235 million, 19% IRR and initial capex of $184 million, with copper accounting for 77% of payable metal. Hot commissioning of the process plant is targeted for Q3 2027, with first production in December 2027 and scope to extend mine life using inferred resources and the separate Ulveryggen deposit.

    Technical Brief

    • Feasibility study considers only the underground Nussir deposit; Ulveryggen resources are excluded from economics.
    • Measured and indicated resources of 28.72 Mt at 1.2% CuEq include ~25 Mt proven and probable at 0.99% CuEq.
    • Deposit remains open to the west and at depth, with 200 m step-out drilling at >1,000 m depth ongoing.
    • Scenario using 50% of inferred resources adds 5 years’ mine life and lifts NPV by an estimated 52%.
    • Long-term price deck underpinning the case uses US$4.78/lb Cu, US$3,515/oz Au and US$45.26/oz Ag.
    • Payable metal revenue split is heavily copper-weighted: 77% Cu, 6% Au and 13% Ag.
    • Nussir is a brownfield redevelopment of a 1970s operation that mined four shear-hosted open pits until 1979.
    • Blue Moon acquired Nussir in late 2024 to rebalance away from its California zinc project toward near-production copper.

    Our Take

    Blue Moon Metals’ move into the Nussir copper project in northern Norway follows its acquisition of the Apex gallium‑germanium‑copper mine in Utah, signalling a strategy of building a portfolio of polymetallic assets with both base and critical metals exposure across the US and Europe.

    An initial capex of about US$184 million for Nussir against a market capitalisation near US$710 million suggests Blue Moon has balance-sheet capacity to advance the project without immediately resorting to highly dilutive equity, though the 13‑year mine life and 0.99–1.2% CuEq grades mean project finance will likely hinge on securing robust copper and silver offtake terms.

    Integrated Pump Technology in Central Africa: dewatering design notes for mine engineers

    Integrated Pump Technology is expanding dewatering support in Central Africa’s mines as more erratic, climate-driven rainfall increases pit flooding and sump inflows, deploying Grindex submersible units and Godwin diesel-driven surface pumps for both open-pit and underground operations. The company is pairing high-solids, high-head pump selections with local distributor partnerships and on-site application audits to match pump curves to specific shaft depths, static heads and slurry loadings. For mine operators, the focus is on maintaining pumping capacity during peak storm events and reducing unplanned downtime from flooded haul roads, declines and pump chambers.

    Sandvik Rock Processing Reborn in Africa: retrofit economics for mine engineers

    Sandvik Rock Processing’s Reborn programme is gaining uptake at African mines and quarries seeking higher throughput from existing primary and secondary crushers while limiting capex. The scheme replaces ageing crusher cores with new Sandvik units in the original frames and foundations, allowing plants to retain chutes, civils and conveyors while upgrading to current crusher technology and automation. PC Kruger, Business Line Manager Crushing, positions Reborn as a step beyond standard refurbishment, targeting faster installation, reduced downtime and predictable lifecycle costs.

    Cementation Africa in deep underground mining: design and risk insights for engineers

    Africa’s push into deeper, more complex underground orebodies is driving demand for specialist contractors such as Cementation Africa, which combines shaft sinking and raiseboring capability with in‑house engineering and risk management. The contractor is focusing on technically challenging work, including high-stress rock mass conditions, complex ground support regimes and critical‑path access infrastructure for new critical minerals projects. For mine owners, the key shift is from pure construction procurement to integrated delivery models where design, construction methodology and risk allocation are tightly coupled.
