BLUE SKY URANIUM HIGHLIGHTS AMARILLO GRANDE IN 2026 NEA/IAEA GLOBAL URANIUM REPORT

Blue Sky Uranium Corp.'s flagship Amarillo Grande uranium-vanadium project has been included, including the Ivana deposit, in Uranium 2026: Resources, Production and Demand, the latest edition of the internationally recognized "Red Book" published jointly by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA).

The 2026 Red Book provides an extensive review of uranium resources, exploration, development and production worldwide and includes a detailed national report for Argentina. The report summarizes Ivana's exploration programs and key data from the deposit's 2024 preliminary economic assessment. These figures are listed alongside and compared with those for other deposits and resources in Argentina and around the world. Based on the figures presented in the Red Book, Ivana has the largest uranium resource among the seven Argentine deposits when inferred resources are not included, and the third-largest total uranium resource.

Within the report, Ivana (Amarillo Grande) is identified as one of only four prospective uranium production centres in Argentina, together with Laguna Salada, Sierra Pintada (in remediation), Cerro Solo (in standby). Of the four, Ivana is listed with highest nominal production capacity. In a global context, when comparing planned and prospective uranium mines with open-pit style mine plans Ivana is listed with the sixth-largest nominal production capacity.

Nikolaos Cacos, president and chief executive officer of Blue Sky Uranium, commented: "The inclusion of Amarillo Grande and the Ivana deposit in the latest NEA/IAEA Red Book provides important context for the project within Argentina's uranium sector, as well as within the broader global uranium community. We believe Amarillo Grande is well positioned as Argentina evaluates the potential re-establishment of domestic uranium production, and we are continuing to advance Ivana together with our joint venture partner."

The 2026 Red Book also places Amarillo Grande within the broader setting of Argentina's efforts to potentially re-establish domestic uranium production. Argentina historically produced 2,582 tU between 1952 and 1997, principally to satisfy domestic uranium requirements, but has had no uranium production since 1997.

The Red Book notes that both the Argentine government and industry are conducting exploration and development activities with the objective of supporting the potential restart of domestic uranium production and future uranium self-sufficiency.

The report also notes that in November, 2025, the IAEA conducted an integrated uranium production cycle review mission to assess Argentina's readiness to restart uranium mining.
