On September 25, 2026, Norway gave its Climate Ministry formal legal authority to reverse a decade-old Royal Decree that upheld the Engebø mine's sea-disposal permit after the country's Supreme Court found that permit invalid.
The reversal mechanism centers on Engebø, but Viceroy Research says Norway is now examining whether Blue Moon Metals' Nussir project carries the same legal defect, while separately arguing that Nussir's orebody and cost assumptions leave the mine with little economic margin even if its permit survives.

Position Disclosure: Viceroy Research states that its authors, members, partners, affiliates, employees, consultants, and/or capital-provider counterparties may hold direct or indirect positions in covered issuers and may profit if prices decline. It also states it may receive compensation for pre-publication disclosure of report information and through other arrangements.
Thesis
Viceroy Research argues that Norway's reversal of Engebø's sea-disposal permit exposes Blue Moon Metals' Nussir project to similar permitting risk, compounding what it calls thin economic margins in the mine plan.
- Permit Reversal Mechanism: Norway's September 25, 2026 notice delegated authority to the Ministry of Climate and Environment to reverse the February 19, 2016 Royal Decree that upheld Engebø's sea-disposal permit, after the Supreme Court ruled in June 2026 that the permit failed Article 4(7) of the Water Framework Directive.
- Nussir Defect Examination: Viceroy alleges Norway is examining whether Blue Moon's Nussir permit carries the same legal defect that invalidated Engebø's approval, though the report cites no specific filing or government statement documenting this review.
- Thin, Wavy Orebody: Nussir's mine plan reportedly needs at least three meters of mining width to run efficiently, but the ore is commonly two to four meters wide and locally narrows to less than one meter.
- Narrow Break-even Margin: Viceroy's prior report pegs Nussir's break-even cushion at roughly US$30 to US$35 per tonne, based on a reserve-tonne NSR of about US$65 to US$70 against a US$35.43 cut-off.
- Optimistic Cost Assumptions: Nussir assumes site operating costs of about US$26 to US$30 per tonne, versus nearby Zinkgruvan's implied cost of more than US$80 per tonne on US$115 million of production costs over roughly 1.35 million tonnes milled.
- Ministry's Reversal: Norwegian officials called an immediate halt to Engebø's disposal "unreasonable" in a June 29, 2026 statement citing jobs and strategic-metal supply, months before the government moved to reverse the permit framework behind that same disposal activity.
Catalysts
- Formal exercise of delegated reversal authority: Pending regulatory action; would confirm permit revocation at Engebø and strengthen the read-across risk to Nussir.
- Determination on whether Nussir shares the same legal defect: Pending; a finding against Nussir would directly threaten Blue Moon's project permit.
- Decision on Engebø's temporary permit application: Pending regulatory decision; outcome signals how Norway may treat Nussir if a similar defect is found.
Company Response
The report does not indicate that Blue Moon Metals, Nordic Mining, or any Norwegian government body was asked for comment. No response from Blue Moon Metals or any other named party is reported.
Notable Details
- Norway's September 25 notice cites the original case file, No. 15/3378, directly naming the 2016 Royal Decree now subject to reversal.
- The 2016 decree had rejected appeals from four environmental groups, Natur og Ungdom, Naturvernforbundet, Vevring og Førdefjorden Miljøgruppe, and Norske Lakseelver, each of which had contested the original Engebø permit.
- The report does not cite any stock price, trading volume, or market capitalization data for Blue Moon Metals.
- Viceroy's cost comparison draws on its earlier report, "Blue Moon Metals: License to Shill" (August 12, 2026), which first laid out the mine's break-even assumptions.
"It has been striking to watch Norwegian public officials, whose core mandate is environmental protection, repeatedly defend Engebø and Nussir; two mines with limited, if any, commercial viability even if they were permitted to operate."
Viceroy Research uses this to frame what it sees as a conflict between officials' public support for the projects and the mines' legal and economic exposure.
FAQs
What is Blue Moon Metals (MOON.V) and what is its connection to Nussir?
Blue Moon Metals, trading on the TSX Venture Exchange as MOON.V, is the company behind the Nussir mining project in Norway. The project's permit is now under scrutiny after Norway moved to reverse a related sea-disposal approval at the nearby Engebø mine, according to Viceroy Research.
What is Nussir, the project at the center of Blue Moon Metals' permitting risk?
Nussir is Blue Moon Metals' mining project in Norway. Viceroy Research says Norway is examining whether Nussir's permit has the same legal defect found in the nearby Engebø mine's sea-disposal approval, which Norway's Supreme Court ruled invalid in June 2026.
What does Viceroy Research allege about Blue Moon Metals' permitting risk?
Viceroy Research, which holds a short position in Blue Moon Metals, alleges that Norway's September 2026 move to reverse the Engebø sea-disposal permit signals a regulatory risk that could extend to Nussir's permit. The firm also argues that Nussir's orebody and cost assumptions leave little room for error even if the permit survives review.
What happened to the Engebø mine's permit in Norway?
Norway's Ministry of Climate and Environment originally granted Nordic Mining a permit for rutile extraction and sea disposal of tailings at Engebø in June 2015, upheld by a Royal Decree in February 2016. Norway's Supreme Court declared that permit invalid in June 2026 for failing to satisfy Article 4(7) of the Water Framework Directive, and on September 25, 2026 the government delegated authority to its Climate Ministry to formally reverse the 2016 decree.
Why does Viceroy think Nussir's mine plan is economically risky?
Viceroy states that Nussir's mining plan requires at least three meters of mining width to operate efficiently, while the ore seam is commonly two to four meters wide and locally narrows to less than one meter. The firm describes this as a thin, wavy seam that leaves little room for dilution or mining losses.
How does Nussir's break-even margin compare to other Nordic mines?
Per Viceroy's earlier report, Nussir's reserve-tonne net smelter return averages roughly US$65 to US$70 against a US$35.43 cut-off, implying a break-even margin of about US$30 to US$35 per tonne. By comparison, nearby Zinkgruvan's reported production costs imply more than US$80 per tonne, well above Nussir's assumed US$26 to US$30 per tonne operating cost.
Has Blue Moon Metals responded to the Viceroy report?
The report does not indicate that Blue Moon Metals, Nordic Mining, or any Norwegian government body was asked for comment, and no company response is reported.
What would happen if Norway finds Nussir's permit has the same defect as Engebø's?
The report does not specify the consequence, but it draws a direct parallel: Engebø's permit is now headed toward formal reversal after the Supreme Court found it invalid, and Viceroy says Norway is examining whether Nussir's permit suffers the same defect. Viceroy does not cite a specific filing or government statement confirming this examination, so the Nussir link remains an allegation rather than a documented finding.
