Blue Sky Uranium Reports Detailed Modelling of Higher-Grade Domain Demonstrating Continuity in the Core Zone of the Ivana Deposit, Amarillo Grande Project, Argentina
Higher Grades Found in Ivana’s Initial Mining Zone as Strategic Partner Funds De-Risking

The February 17, 2026, news release details geological modelling of a higher-grade uranium domain within the Ivana deposit at the Amarillo Grande project in Argentina. Based on 2025 drilling, the company identified a domain with a footprint of 505m x 132m and thicknesses up to 17m. Key intercepts include 13m at 943 ppm U3O8 (AGI-1157) and 13m at 922 ppm U3O8 (AGI-1159). Crucially, 34% of this modelled domain was not included in the 2024 mineral resource estimate, representing an expansion of the high-grade core. Management notes this area is intended to be the starting point for potential mining operations as per the 2024 Preliminary Economic Assessment (PEA).
The news is Material - Positive for three primary reasons: - Incremental Resource Growth: The identification that 34% of this high-grade domain is "new" implies an upcoming resource update will likely see an increase in both total pounds and average grade. - Early-Year Economics: Since this area is the planned "Phase 1" of mining, higher grades here directly improve the payback period and internal rate of return (IRR) by increasing cash flow in the critical early years of the project. - Continuity Validation: The 27-hole program confirms the continuity of mineralization that was previously considered higher-risk due to wide drill spacing.
However, the impact is tempered by the fact that these are relatively shallow, low-grade deposits compared to Athabasca Basin peers (though they are surficial and potentially lower cost).
Blue Sky Uranium is an exploration/development company focused on Argentina. Its flagship is the 100%-owned Amarillo Grande Project, specifically the Ivana Deposit. - Project Type: Surficial uranium-vanadium mineralization. - 2024 PEA Stats: After-tax NPV (8%) of $227.7M USD, 38.9% IRR, 11-year mine life based on $75/lb U3O8. - Strategy: Moving Ivana toward production while exploring the 145km-long district for "cluster" deposits to feed a central plant.
