Blue Sky Uranium presented a detailed geological model identifying a higher-grade zone within and adjacent to the mineralized core of the Ivana deposit, at the Amarillo Grande Project, Río Negro Province. The work, based on infill and expansion drilling data completed in 2025, confirms lateral continuity of mineralization and opens the door to future adjustments in resources and development economic parameters.

The new model defines a mineralized domain with an approximate footprint of 505 meters by 132 meters and thicknesses ranging from 1 to 17 meters, integrating information from 27 drill holes. According to the company, approximately 66% of the area had already been incorporated into the 2024 resource estimate, while the remaining 34% represents a potential extension of the core that could translate into additional uranium pounds in future updates.
Three-dimensional sections show that mineralization extends from the central zone defined in the 2024 PEA toward previously underexplored sectors due to access limitations, consolidating the “starter zone” concept as the initial point of a potential operation. The company indicated that full integration of the infill program data will be the next step before advancing toward a new resource estimate and Prefeasibility studies.
Drilling Results and Methodology
Reported assays include highlighted intervals of up to 943 ppm U₃O****₈ over 13 meters, along with multiple intersections above 500 ppm, confirming associated uranium and vanadium mineralization. All drill holes were vertical, and the reported intervals are considered representative of true thickness, consistent with the sedimentary geometry of the deposit.
From a technical standpoint, the campaigns were carried out using reverse circulation drilling with FlexiROC D65 rigs and a triple cyclone system to reduce dust loss and ensure sample representativity. Samples were analyzed at ALS laboratories using multi-element acid digestion and ICP-AES and ICP-MS instrumentation, with the insertion of standards, blanks, and duplicates representing 10.5% of the QA/QC program, within standard industry parameters.
Economic Implications and Project Positioning
Although the company’s release does not include a formal economic update, it noted that strengthening the core zone could positively influence future Prefeasibility evaluations, particularly by concentrating higher-grade mineralization in the early stages of potential production. The Ivana Project is operated by Ivana Minerales S.A. under a joint venture between Blue Sky Uranium and Corporación América, through an earn-in structure that contemplates cumulative investments of up to US$160 million to achieve a majority interest and advance toward potential construction.
Amarillo Grande remains the flagship asset in the company’s Argentine portfolio and one of the most advanced uranium developments in the country. In a global scenario marked by renewed interest in minerals associated with the energy transition, the geological update strengthens the project’s technical narrative and anticipates a stage of greater definition toward engineering studies and more detailed economic evaluation.
The incorporation of a higher-grade zone within the Ivana deposit marks another step in the technical maturation of Amarillo Grande. Beyond the specific results, the modeling confirms mineralized continuity and consolidates the geological foundation necessary to advance toward more economically defined phases within one of Argentina’s most relevant uranium projects.
