Blue Moon Metals Inc. (TSXV: MOON; NASDAQ: BMM) shares fell after short-selling firm Viceroy Research published a critical report on the company on August 12, 2026, and the company issued a detailed rebuttal the following day. The dispute centers on Blue Moon’s flagship Nussir copper-gold-silver project in northern Norway, along with the value of a recently expanded U.S. portfolio of tungsten, germanium, and gallium assets. Readers should understand this as an active, unresolved dispute between two parties who each have a financial stake in the outcome, rather than a settled matter.

What Viceroy Alleges

Viceroy’s report, titled “License to Shill,” argues that Blue Moon is built around a Norwegian copper project whose tailings disposal permit is at risk following a June 2026 Norwegian Supreme Court ruling, and that its U.S. mining assets were acquired cheaply but are being presented to investors as worth far more than that. Viceroy also alleges that company management withheld unfavorable regulatory information from investors while raising roughly C$156 million from retail shareholders, and separately argues that a forward sale of Nussir’s future output to commodities trader Hartree does not channel those critical minerals toward European, Canadian, or Norwegian supply chains. Viceroy has publicly disclosed that it holds a short position in Blue Moon’s stock, meaning the firm profits if the share price falls.

What Blue Moon Says in Response

Blue Moon’s rebuttal states that all of Nussir’s permits remain in good standing and that construction is proceeding on schedule toward targeted 2027 production. The company argues the Norwegian Supreme Court ruling Viceroy cites, which concerned a different, unrelated mining project roughly 1,300 kilometers away, does not directly apply to Nussir, and says Norway’s government has explicitly declined to treat the two projects’ permits as automatically equivalent. On financing, Blue Moon says it holds enough cash to fully repay its $25 million credit facility with Hartree and Oaktree if needed, and that repayment isn’t contingent on how the permitting question is resolved. On its U.S. assets, the company says a roughly five-fold jump in tungsten prices since it agreed to acquire the Springer complex has materially improved that asset’s economics. Blue Moon did not address Viceroy’s specific concealment allegation or the C$156 million retail fundraising claim by name in its release.

What’s Actually Verifiable

A few facts sit outside either party’s spin. Norway’s Supreme Court did rule in June 2026 on a permit dispute involving Nordic Mining’s separate Engebø project, finding the justification behind that project’s 2016 permit didn’t satisfy EU water-law requirements, and Norway’s government is now reassessing that permit. That reassessment does not, by itself, apply to Nussir’s permit, and Norway’s government has stated it will separately consider whether the ruling has any bearing on Nussir at all, a process that is still underway with no outcome yet. The EFTA Surveillance Authority separately sent Norway’s government a formal enforcement notice referencing Nussir, which is a procedural step that gives the government a chance to respond, not a ruling or a permit revocation. In short, the regulatory question both sides are describing is genuinely open, not resolved in either direction.

Why This Matters for Readers

Short-seller disputes are inherently adversarial: the firm making allegations benefits financially if the stock falls, and the company disputing those allegations benefits if it doesn’t. That doesn’t make either side’s claims true or false on its own, but it’s a reason to treat both sets of assertions as claims rather than settled fact until independent developments, a Norwegian government decision on the Nussir permit, for instance, clarify the picture. Investors following this story will likely want to watch for the outcome of that government reassessment rather than relying on either party’s current characterization of it.

Viceroy Research has publicly disclosed a short position in Blue Moon Metals securities and stands to profit if the share price declines; Blue Moon Metals has a corresponding financial interest in disputing allegations that could affect its share price.
