Blue Moon Commences Construction of Exploration Decline at its Blue Moon Mine in Mariposa County, California

TORONTO, Oct. 6, 2025 /PRNewswire/ - Blue Moon Metals Inc. ("Blue Moon" or the "Company") (TSXV: MOON) (OTCQX: BMOOF), is pleased to announce that construction of the exploration decline at its Blue Moon volcanogenic massive sulphide ("VMS") project (the "Project"), located in Mariposa County, California, officially commenced on October 5, 2025.

This marks a major milestone in advancing the Project, following the award of the contract to Small Mine Development, L.L.C. ("SMD") earlier this year (see June 26, 2025 news release). The decline will provide underground access for infill and exploration drilling, geotechnical and metallurgical test work, and studies of underground mining conditions. These activities are critical to supporting future feasibility studies and a potential mine commercialization decision.

The CEO of Blue Moon, Christian Kargl-Simard stated:

"The commencement of decline construction is a transformative moment for Blue Moon. Moving underground allows us to accelerate exploration drilling and technical studies, while maintaining a very small surface footprint. We are excited to advance toward unlocking the full potential of the Blue Moon deposit and to continue working closely with SMD, our local partners, and the Mariposa County community."

Portal construction activities began on October 5 and the initial 2,500 feet of the exploration decline is expected to be completed in Q2-2026. Exploration drilling activities will commence from underground concurrently with the advance of the decline, enabling the Company to accelerate the collection of geological, geotechnical and metallurgical data in parallel with ongoing development. The Company is committed to supporting the economic and social development of the local and regional communities.
