BLUE MOON AWARDS MINING CONTRACT FOR THE CONSTRUCTION OF THE PORTAL AND EXPLORATION DECLINE

FOR ITS BLUE MOON MINE IN MARIPOSA COUNTY, CALIFORNIA

TORONTO, Ontario – June 26, 2025 – Blue Moon Metals Inc. (“Blue Moon” or the “Company”) (TSXV: MOON; OTCQB:

BMOOF), is pleased to announce the award of a contract to Small Mine Development, L.L.C. (“ SMD”) for the

construction of a portal and decline to enable underground mineral exploration activities at the Blue Moon

volcanogenic massive sulphide (“ VMS”) deposit (the “ Project”), located in Mariposa County, California. This

construction work represents a significant step forward for the Project’s development, as the portal and decline will

provide access for infill and exploration drilling, and allow for further studies and investigations related to geology, rock

mechanics, underground mining conditions, and metallurgical test work and ultimately to a mine co mmercialization

decision.

Blue Moon undertook a formal request for proposal (“RFP”) process (see April 15, 2025 news release) to select a mining

contractor, from which several proposals were received. SMD ultimately provided a proposal that was consistent with

the Company’s Project objectives for Health & Safety, local employment, cost, schedule, and performance, making

them a clear choice for the award of this contract.

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

"The award of this contract represents a major step forward in the development of the critical metals related Blue Moon

Mine. The ability to access the orebody from underground will greatly accelerate the Company’s plans to wards a mine

commercialization decision, and the minimal footprint at surface allows us to do so in a very responsible manner – both

physically and environmentally. We are proud to have SMD as a partner on this significant milestone .”

Execution planning and additional engineering work to support construction will commence immediately, followed by

the start of portal development in Q3-Q4 of this year. The exploration decline is expected to be complete by Q3 -2026

and will include an underground exploration drilling campaign along with the aforementioned additional study work.

This initial construction work is expected to generate at least 20 local employment opportunities directly with the mine

and through SMD and their subcontractors. The Company is committed to supporting the economic and social

development of the local and regional communities.
