BLUE MOON AWARDS MINING CONTRACT FOR THE CONSTRUCTION OF THE PORTAL AND EXPLORATION DECLINE FOR ITS BLUE MOON MINE IN MARIPOSA COUNTY, CALIFORNIA

Blue Moon Metals Inc. has awarded a contract to Small Mine Development LLC (SMD) for the construction of a portal and decline to enable underground mineral exploration activities at the Blue Moon volcanogenic massive sulphide (VMS) deposit, 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 and underground mining conditions, metallurgical test work, and, ultimately, to a mine commercialization 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 and safety, local employment, cost, schedule, and performance, making it a clear choice for the award of this contract.

Christian Kargl-Simard, chief executive officer of Blue Moon, 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 towards 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 to 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.
