Vancouver, British Columbia-- March 19, 2026 - Blue Sky Uranium Corp. (TSXV: BSK) (FSE: MAL2) (OTCQB: BKUCF), ("Blue Sky" or the "Company") and Ivana Minerales S.A. ("IMSA", the operating company for the joint-venture between Blue Sky and a subsidiary of Corporacion America Group, "COAM") are pleased to announce the initiation of a hydrogeological study in the vicinity of the Ivana uranium-vanadium deposit within its 100%-owned Amarillo Grande Project in Rio Negro Province, Argentina. The program is designed to evaluate potential water sources required to support future mining and processing operations, as well as to characterize groundwater conditions relevant to potential mine dewatering requirements.

The hydrogeological program will include geophysical surveys, drilling of exploratory water wells, installation of groundwater monitoring piezometers, short- and long-duration pumping tests, water quality analysis, and the development of a hydrogeological model for the project area. The results of this work will support ongoing technical studies related to future development of the Ivana deposit.

The program commenced in early March and is estimated to require approximately five months to complete. The cost of the hydrogeological study is currently estimated at approximately US$400,000, excluding additional work such as drilling of water wells and pumping tests, which will be defined as the program advances.

Nikolaos Cacos, Blue Sky President & CEO commented, "Advancing hydrogeological studies is an important step in the technical progression of the Ivana deposit toward future development stages. Understanding groundwater conditions and identifying reliable water supply options early in the engineering process helps reduce project risk and supports the advancement of the project toward Pre-Feasibility and Feasibility level studies."

The hydrogeological study is being carried out by Hidroar S.A., a specialized Argentine hydrogeological consulting firm with more than 30 years of experience providing groundwater and water resource services to the mining, oil & gas, institutional and infrastructure sectors.
