Blue Moon Metals Begins Construction of Exploration Decline at Mariposa County Mine

TORONTO, Oct. 6, 2025 — Blue Moon Metals Inc. (TSXV: MOON) (OTCQX: BMOOF) announced that construction of the exploration decline at its Blue Moon volcanogenic massive sulphide (VMS) project in Mariposa County, California officially commenced on October 5, 2025.

This milestone advances the project following the earlier award of the contract to Small Mine Development, L.L.C. (SMD) (see June 26, 2025, news release). The underground decline will provide access for infill and exploration drilling, geotechnical and metallurgical testing, and studies of underground mining conditions—activities that are essential for future feasibility studies and the potential commercialization of the mine.

“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,” said Christian Kargl-Simard, CEO of Blue Moon.

Exploration Decline Details

Portal construction began October 5, and the first 2,500 feet of the decline is expected to be completed by Q2-2026. Underground drilling will start concurrently with the decline advance, enabling accelerated collection of geological, geotechnical, and metallurgical data while construction progresses.

Blue Moon is committed to fostering economic and social development within the local and regional communities, ensuring that project advancement brings tangible benefits alongside technical progress.

European Outreach for Investor Relations

The Company also announced an agreement with SRC Swiss Resource Capital AG (SRC) for investor relations and communications services in Europe, effective October 6, 2025, for a one-year term with automatic quarterly renewals. Either party may terminate the agreement with seven days’ notice.

Under the agreement, SRC will provide:

  • Investor communications and media dissemination
  • Interviews and video content
  • Representation at trade and investment shows

The services will be compensated at 5,000 CHF per month, with additional fees for special services, supporting Blue Moon’s outreach to European investors and enhancing its visibility in international markets.

Expanded Project Context

The Blue Moon VMS project represents a high-potential polymetallic deposit, and the underground exploration decline is a key step in advancing technical knowledge ahead of potential mine development. By combining underground access with modern drilling and testing methods, Blue Moon can accelerate decision-making while minimizing environmental and surface impacts.

“Moving underground is a game-changer for our exploration program,” added Kargl-Simard. “It allows us to generate high-quality data faster and continue working responsibly with the Mariposa community, ensuring that the project supports both resource development and local prosperity.”

The project aligns with Blue Moon’s strategy of responsible and efficient resource development, leveraging technical innovation and community engagement to advance towards potential commercial operations while preparing for future feasibility studies and permitting processes.
