On September 4, 2025, Blue Moon completed:

On September 4, 2025, Blue Moon closed the Initial Equity Subscription and through its subsidiary, Nussir ASA, completed the initial draw of US$12.5 million under the Bridge Loan. Concurrent with the first draw-down under the Bridge Loan, the Company issued 1,045,000 common shares of the Company (the "Bonus Shares") to Hartree.

Blue Moon had entered into (i) a subscription agreement dated August 19, 2025 in respect of the Initial Equity Subscription, (ii) a loan agreement dated August 19, 2025 (as amended on September 2, 2025) providing for a US$25 million Bridge Loan, which may be drawn in two installments of US$12.5 million (with the initial US$12.5 million drawn on September 4, 2025) upon the satisfaction of certain standard conditions precedent, and (iii) a non-binding letter of intent dated August 19, 2025 providing for (A) an equity investment of up to US$20 million from Hartree and funds managed by Oaktree, which may be completed upon the occurrence of certain events and capped to maintain ownership below a 19.9% threshold between Hartree and Oaktree, of which, US$5 million closed on September 4, 2025 as the Initial Equity Subscription, and (B) up to an aggregate US$120 million of non-dilutive funding by way of a senior secured term loan and a redeemable precious metals stream, subject to customary milestones and closing conditions. As such, the Initial Equity Subscription and the Bridge Loan represent the first stages of a larger investment package which can provide for up to US$140 million of support for the continued development and construction the Company's flagship, fully permitted Nussir Copper Project, located in Norway.

The capital from the initial draw under the Bridge Loan and the Initial Equity Subscription is intended to support key early works and pre-construction activities including detailed engineering, procurement of long-lead items, underground development, and operational readiness. The Bridge Loan is structured to provide working capital for Nussir ASA's advanced stage sediment hosted development copper-gold-silver project located in northern Norway (the "Nussir Project"), and for the advancement of the Company's polymetallic volcanogenic massive sulfide deposit located in central California. The US$50 million senior secured term loan and US$70 million redeemable precious metals stream are contemplated to be used for the completion of the Nussir Project, following the satisfaction of certain defined conditions.

Following the closing of the Initial Equity Subscription and the issuance of the Bonus Shares, approximately 13.37% of the voting rights attached to outstanding common shares of the Company are controlled, directly or indirectly by Oaktree.

All securities issued under the Initial Equity Subscription and the Bonus Shares are subject to a hold period expiring four months and one day from the issue date in accordance with applicable Canadian securities laws.
