Blue Sky Hosts Community and Stakeholder Water Sampling Event at the Ivana Uranium-Vanadium Project, Argentina

Blue Sky Uranium Corp. (TSX-V: BSK, FSE: MAL2; OTC: BKUCF), ("Blue Sky" or the "Company") is pleased to announce that on May 28, 2025, Ivana Minerales S.A. completed the first participatory groundwater sampling at the Ivana Uranium-Vanadium Project, (the “Project”). This was a precursor to the recently announced infill drilling program that marks a major step toward the prefeasibility/feasibility phase of the Project (see News Release dated May 22, 2025). While the sampling was carried out as a legal requirement for the drill program, the event marks a crucial step toward establishing an open, citizen-inclusive environmental monitoring process that meets high technical standards. This reflects the Company’s commitment to responsible environmental management and the development of trusted relationships within the region.

The participatory sampling event was attended by landowners from the Project area and residents of the town of Valcheta, which is located approximately 25km from the Ivana properties and serves as a major source of labour and operational support for the Project. Representatives from Valcheta included the town’s Mayor, members from the City Council, the local hospital, the museum, and educational institutions. Provincial agencies in attendance included the Secretariat of Mining of Río Negro, the Secretariat of Environment and Climate Change, the Provincial Water Department, the Office of the Ombudsman, and members of the Río Negro Legislature.

Nikolaos Cacos, President & CEO of the Company, stated: “We are committed to building a relationship founded on transparency and mutual trust with the Valcheta community and the authorities of Río Negro, through our professional and dedicated approach to the Ivana Project. Joining community members and regulatory authorities to participate in environmental water sampling helps us to strengthen our relationships as we work together to develop an environmentally and socially sustainable project.”

The event was led by Luis Rivera, General Manager of Ivana Minerales S.A., and Silvia Rodríguez, Head of Community Relations. They welcomed attendees and provided a brief overview of the Project's objectives and the sampling protocol to be followed.

Technical tasks were carried out by the specialized consulting firm Hidroar S.A., which is currently responsible for the environmental baseline study for the Ivana Project. This study, initiated in 2022, compiles climate data, surface and groundwater sampling, flora and fauna assessments, archaeological and paleontological surveys, and other environmental and social components to create a documented record of the area's environmental conditions prior to any potential future production.

During the event, the Hidroar team provided detailed field explanations of the methodology used. Sampling was conducted at three strategic points established by regulation: upstream, midstream, and downstream of the area designated for potential future drilling. Simultaneously, the Provincial Water Department (DPA) collected duplicate samples at the same locations, using an independent but technically equivalent procedure, thus ensuring the traceability, reliability, and transparency of the data collected.
