BLUE MOON METALS SELECTS WORLEY TO PREPARE A NI 43-101 FEASIBILITY STUDY FOR THE NUSSIR PROJECT IN Q1-2026 AND ADVANCE BASIC ENGINEERING

Blue Moon Metals Inc. has selected Worley Ltd., a leading global professional services company of energy, chemicals and resources experts, as the engineering contractor for the update from the May, 2023, SRK JORC-compliant (Joint Ore Reserves Committee) feasibility study to a maiden National Instrument 43-101 feasibility study and advancement of the basic engineering on its flagship Nussir copper-gold-silver project in Norway. The basic engineering on the process plant will allow Blue Moon Metals to order long-lead items in Q4 2025. Detailed engineering is expected to follow from the basic engineering in 2026.

The decision follows a competitive tender and evaluation process to identify a top-tier engineering partner to update the May, 2023, JORC-compliant feasibility study and to advance the project to basic engineering and support the construction decision. This update will provide a solid base for the construction of the full project following the start of the exploration decline in June, 2025. Worley brings deep expertise in advancing base metal projects with deep knowledge and understanding of delivering projects in Norway. The engineering work will be conducted primarily through Worley's offices in both United Kingdom and Canada.

"We are very excited to partner with Worley to unlock the potential of the Nussir project and advance towards long-lead equipment purchase and construction," said Christian Kargl-Simard, chief executive officer of Blue Moon. "Their strength in mining and mineral processing and ongoing project delivery in Norway provide a unique combination of global expertise and local project execution for the Nussir project."

The feasibility study update will incorporate the results for the continuing mine decline construction, updated capital and operating expenditure and will incorporate innovations in the mine design and process facility, including optical sorting, to improve the project outcome. The study will also focus on advancing several value optimization opportunities in mine planning, process facility and infrastructure. The results from the feasibility study update are expected in Q1 2026.
