Worley Europe completed the project feasibility study, and basic engineering is progressing toward an EPCM contract award scheduled for May 2026
Decision Lens
The Nussir underground copper project in Finnmark, Norway is making capital-committing decisions ahead of its anticipated final investment decision in the first half of 2026. Long-lead process plant equipment — SAG mill, ball mill, thickeners — and the main power transformer have already been ordered to protect a compressed construction schedule. These pre-FID procurement choices, combined with a fixed underground design using long-hole open stoping, mean the project’s operational architecture is substantially set. For operations directors benchmarking underground copper development or managing brownfield capital projects, Nussir represents a live case where schedule risk management decisions are being made in real time.
90-Second Brief
Now, blue Moon Metals is developing the Nussir underground copper project in Arctic Norway, targeting first production in December 2027 against a 13-year mine life and $184m initial capital estimate from a feasibility study completed in April 2026. The project holds proven and probable reserves of 24.98 million tonnes grading 0.81% copper, with average annual output expected at 19,000 tonnes of copper equivalent. The European Commission recognised Nussir as a Strategic Critical Raw Material Project under the EU Critical Raw Materials Act in June 2025. A financing package of up to $140m has been structured with Hartree Partners and Oaktree Capital Management under a memorandum of understanding signed in August 2025.
What’s Actually Happening
Nussir is moving from feasibility into construction execution. The first blast at the decline access portal occurred in June 2025, opening underground development works. Norwegian tunnelling and mining services firm Leonhard Nilsen & Sønner has been appointed mining contractor. Worley Europe completed the project feasibility study, and basic engineering is progressing toward an EPCM contract award scheduled for May 2026.
The decision to order long-lead mill equipment and the main power transformer before the EPCM contract is placed reflects an explicit strategy to remove critical-path delay risk ahead of formal construction mobilisation. SAG mill and major rotating equipment delivery windows from OEMs have become a scheduling constraint across the industry, and Nussir’s team has moved to de-risk that exposure early.
The underground method — long-hole open stoping with ribs and sill pillars, 3m minimum mining width, and 95% estimated mining recovery — feeds mobile underground crushers before material is conveyed to a surface circuit: SAG mill, ball mill, flotation, and pressure filtration to produce copper concentrate. Export is planned through an ice-free port at Øyen, which Blue Moon Metals acquired with ship-loading infrastructure in March 2025.
Why It Matters for Mining Operations Directors?
The pre-FID procurement approach at Nussir is operationally instructive. Purchasing the power transformer and long-lead mill equipment before EPCM award is a deliberate compression of the critical path in a 30-month build schedule. Operations directors managing brownfield expansions or capital equipment replacement programs face the same sequencing question: at what point does deferring procurement to maintain process control create a schedule liability that outweighs the risk of early commitment?
The underground design choices carry their own implications. Mobile underground crushing feeding a surface grinding circuit avoids the throughput variability of direct truck-to-surface haulage, but embeds its own constraints: crusher availability underground becomes a production chokepoint, and maintenance access in a decline environment differs materially from surface operations. The 3m minimum mining width also constrains flexibility in narrower ore zones — a design tradeoff between dilution control and stoping efficiency.
The EU Strategic Critical Raw Material designation introduces a potential pathway for accelerated permitting and access to European financing mechanisms. The practical benefit within Norwegian regulatory frameworks has not been confirmed in available source material, but the designation signals a project priority status that may reduce administrative exposure.
The Forward View
The EPCM contract award in May 2026, followed by the first concrete pour for the mill building in July 2026, will indicate whether Nussir’s pre-FID procurement strategy has effectively absorbed the critical-path risk or simply displaced schedule pressure into civil execution. No-load commissioning is targeted for March 2027 and mechanical completion for October 2027 — roughly 17 months from EPCM award to mechanical completion in an Arctic environment with a contractor team that has not yet begun full-scale surface construction on this site.
If Nussir executes to schedule, it becomes a reference case for Arctic underground copper development timelines and for the pre-FID procurement model more broadly. The by-product revenue stream — gold and silver — is partially monetised through the Oaktree precious metals stream covering 70% of payable gold and 75% of payable silver over the life of mine. That structure reduces by-product revenue upside but provides a financing mechanism without dilutive equity. Operations directors at comparable projects considering stream financing should note the long-term revenue exposure embedded in that structure before treating it as a neutral funding tool.
What We’re Uncertain About?
- Financing binding status: The $140m package with Hartree Partners and Oaktree Capital Management remains a memorandum of understanding. Whether binding agreements close in time to fund the May 2026 EPCM award without schedule disruption is unconfirmed. Announcement of executed financing documents would resolve this.
- Arctic execution productivity: The 17-month window from EPCM award to mechanical completion has not been stress-tested against actual site productivity rates in northern Finnmark winter conditions. No third-party construction audit data or early earthworks performance benchmarks are yet available to validate the schedule.
- Ulveryggen deposit development pathway: The feasibility study covers only the Nussir deposit. The Ulveryggen deposit, located 3km south, is not currently in development scope. Whether it enters a future life-of-mine extension — and on what timeline or capital requirement — is not addressed in available information.
- EU designation practical permitting benefit: Nussir’s recognition as an EU Strategic Critical Raw Material Project may streamline regulatory processes, but the specific permitting or timeline implications under Norwegian domestic frameworks have not been confirmed in the source material.
One Question to Bring to Your Team
Given that Nussir ordered SAG mill equipment and the main power transformer before the EPCM contract was placed — accepting early commitment risk to protect a 30-month schedule — where in your current capital project pipeline are long-lead procurement decisions being held until after contract award, and what is the realistic schedule cost of that deferral if OEM lead times extend further?
