Another piece of good news for the country's uranium development project driven by Javier Milei's government. The Amarillo Grande project, located in Río Negro, recorded a key discovery after new geological modeling. The company Blue Sky Uranium, together with its local operator Ivana Minerales SA, confirmed a "high-grade" domain in the Ivana deposit. The new mineralized zone is about 500 by 130 meters and has thicknesses between 1 and 17 meters. 34% of the detected area lies outside the limits estimated in 2024. The announcement reinforces the economic and strategic potential of the deposit.
The data once again place Río Negro on the international uranium map.
A high-concentration core in the Ivana deposit
The exploration campaign carried out between 2025 and early 2026 made it possible to drill an area that had not been studied in depth until now. Access limitations had prevented confirmation of its true extent.
The new modeling determined solid continuity of the mineralization. There is not only uranium. Vanadium was also detected in relevant concentrations.
Nikolaos Cacos, president and CEO of Blue Sky Uranium, explained that this area represents an extension of the core of the deposit. According to preliminary economic studies, a potential mining operation could begin there.
The discovery means that the resource is larger than previously estimated. That will have an impact on the next official resource update.
Economic impact and progress toward pre-feasibility
More mineral in the central area means a better economic equation. By concentrating the resource at the point planned to start the mine, the potential profitability increases.
The company will now move forward with a comprehensive update of the geological model. That step is key to initiating technical pre-feasibility studies.
