Company Announcements

TORONTO , Dec. 1, 2025 /CNW/ - Blue Moon Metals Inc. ("Blue Moon" or the "Company") (TSXV: MOON) (OTCQX: BMOOF), is pleased to provide an update on its activities in Norway, including progress at its flagship Nussir Copper-Gold-Silver Project and exploration drilling and development work underway at the NSG Copper-Zinc Project in advance of exploration drilling.

NUSSIR PROJECT UPDATE

The Nussir underground decline continues to advance steadily. The Company's mining contractor, Leonhard Nilsen & Sønner AS ("LNS"), which began construction in June has advanced a total of 656 metres as of November 27th. This steady progress marks a major step toward establishing underground access for future mine development, infill drilling, and early-stage infrastructure installation.

The Company has secured the main high-voltage transformer, one of the project's key long-lead items, which reduces schedule risk and supports the planned construction sequence.

Early Works Construction – Phase 1 has been successfully completed, establishing the initial construction areas and enabling subsequent development activities. Phase 2 is now underway and includes preparation of additional surface areas required for construction and the pad for the main substation and the incoming transformer.

Upgrades of the administration building, housing, and process plant building are underway, ensuring that essential on-site facilities progress in coordination with underground development.

Engineering Update

The feasibility study is progressing on schedule, with major design reviews now completed. The Company remains on track to publish the full NI 43-101 compliant feasibility study results in February. This study will be an update of the May 2023 JORC compliant feasibility study on the project and is primarily an update on operating and capital costs, capital spent to date and commodity prices.

Long-lead equipment packages have been issued to the market for formal tender to maintain alignment with procurement timelines and support the overall construction schedule.

Additionally, the geotechnical investigation program for the process facility has now been completed, providing important data to support upcoming engineering activities. A final investment decision is still on track for March 2026.

Nussir Exploration: Directional Drilling Program Underway

A surface directional drilling campaign at Nussir started in October. The program is designed to significantly expand the current mineral resource estimate ("MRE"), while testing for extensions of high-grade mineralization at depth. The Nussir geological system is the oldest sediment copper deposit in the world. The current MRE at Nussir is an indicated resource of 28.72 Mt of 1.02% Cu, 0.12 g/t Au and 12.3 g/t Ag and an inferred resource of 32.0 Mt of 1.01% Cu, 0.14 g/t Au and 14.6 g/t Ag starting from surface. See the technical report entitled "Report 43-101 Technical Report On The Mineral Resources Of The Nussir And Ulveryggen Projects, Norway, dated January 24, 2025 (as amended and restated on September 12, 2025) with an effective date of January 20, 2025 (the "Nussir Technical Report"), prepared by Adam Wheeler, B.Sc., M.Sc., C.Eng., Eur Ing., FIMMM.

The initial 4,000 metre directional drilling campaign is being conducted from one mother drill hole, with the deepest extending to approximately 1,250 metres depth. The goal is to infill a 650 metre gap between the current MRE and a historical high-grade intersection recorded in drillhole NUS-DD-14-001, which returned 9.7 metres at 0.93% Cu, 1.35 g/t Pd, 0.28 g/t Au, 0.61 g/t Pt and 11.5 g/t Ag.

The drilling will utilize advanced directional techniques to efficiently test the western extent of the deposit while minimizing surface disturbance and total drilled metres. Six daughter holes will be drilled from the existing mother hole (NUS-DD-14-001, 1,101 m deep), with wedge points placed between 400–700 metres. Drill spacing of approximately 200 metres is expected to support potential conversion to inferred resources under CIM guidelines.

This targeted campaign is designed to:

• Test the block of material surrounding the deeper intersections, which represents an exploration target with an estimated tonnage between 8.5 Mt and 16.5 Mt, grading between 0.7% and 1.3% Cu, 9 to 17 g/t Ag, and 0.1 to 0.15 g/t Au. This potential quantity and grade range is based on a geological model incorporating previous drill results that defined the approximate length, thickness, depth and grade of the portion of the mineral resource estimate.  It is conceptual in nature, and it is uncertain if further exploration will result in the target being delineated as a mineral resource (Section 1.7.1 of Nussir Technical Report).
• Investigate elevated platinum and palladium levels at depth and potentially include in the MRE
• Expand mineralization from the lower limit of the current resource (460 m) to a depth of over 1,000 metres
• Testing down-dip extensions to depths of over 1,000 metres, with step-out capacity to 1,250 metres
• Collecting geotechnical and metallurgical data to support future study phases, including for platinum and palladium

NSG PROJECT UPDATE

At the NSG Copper-Zinc project, activities continue to ramp up. The Company's mining contractor, Fauskebygg AS ("Fauskebygg"), mobilized to site in September and has since completed the necessary improvements to the portal face and entrance. Fauskebygg is currently performing slashing of the first 50 metres of the tunnel to correct irregularities in the existing cross-section. This work is required to ensure equipment can transit in the tunnel safely and efficiently as development progresses.

On the exploration front, the technical team is reviewing and relogging historic Rupsi drill core at the NGU National Core Archive in Løkken. In parallel, the Company has recently completed detailed geological mapping across all mine permit areas. This work has significantly advanced the geological understanding of the district and has resulted in the identification of additional exploration targets for follow-up.

A 10,000 metre underground exploration program at the Rupsi deposit from underground is expected to start shortly. The program is focused on infill drilling and expansion drilling at the 9.23 Mt inferred resource of 1.19% Cu and 0.31% Zn. See the technical report entitled "Report 43-101 Technical Report On The Mineral Resources Of The Sulitjelma Project, Norway, dated February 20, 2025 (as amended and restated on September 12, 2025) with an effective date of May 20, 2025 (the "NSG Technical Report"), prepared by Adam Wheeler, B.Sc., M.Sc., C.Eng., Eur Ing., FIMMM.

There is strong potential to add gold, silver, sulfur and cobalt in the resource. Figure 2 outlines the existing 400 metre long tunnel that is in the process of being extended, and the location of the mineralization at the Rupsi deposit.
