BLUE MOON RECEIVES ENVIRONMENTAL PERMITS AND AWARDS MINING CONTRACT FOR TUNNEL EXTENSION AT NSG IN NORDLAND COUNTY, NORWAY

Blue Moon Metals Inc. has received environmental permits for its planned activities from the Norwegian Environmental Agency and awarded a contract to Fauskebygg AS for the extension of its Rupsi tunnel at Nye Sulitjelma Gruver AS (NSG).

The extension will facilitate more efficient and effective exploration drilling of the Rupsi/Dypet deposits (the Rupsi deposit). This work represents a major milestone for the Sulitjelma project as Blue Moon plans to complete a 10,000-metre exploration drilling program from the tunnel with the intent to upgrade the resource from the inferred category to indicated category, expand on the current resource and gather geotechnical and metallurgical data. The Rupsi deposit currently has an inferred resource of 9,258,000 tonnes at 1.19 per cent copper and 0.31 per cent zinc, as summarized in a National Instrument 43-101 technical report on the mineral resources of the Sulitjelma project in Norway, written by Adam Wheeler and dated May 20, 2025. This report is filed on SEDAR+. Inferred resources are conceptual in nature and there is no certainty that they will be converted into reserves.

Blue Moon undertook a limited formal request for proposal process to select a contractor from within Norway. The proposal from Fauskebygg was well aligned with key priorities for health and safety, local employment, cost, and performance. Activities will commence late Q3 2025, with completion expected in Q3 2027. The associated exploration drilling program will progress concurrently with tunnel advancement. In addition to drilling, the exploration program includes geological mapping, soil and core geochemistry analysis, geophysical surveys, and relogging of historical drill core to further refine the geological model and optimize drill targeting.
