Blue Sky Uranium Corp. is pleased to announce the expansion of the principal target at the Corcovo Uranium Project, located in the Western Malargüe Mining District, Mendoza Province, Argentina. The Company has now reviewed and integrated data from an additional 104 historical oil & gas (“O&G“) wells (part of a larger dataset) into its geological model. These new data build upon the previous interpretation, which was based on 89 O&G drillholes (see News Release, June 4, 2025), and provide stronger support for a substantial uranium mineralized system with significant continuity, based on uranium equivalent (“eU“) and gamma-ray anomalies in the Centenario Core horizon.
A new uranium equivalent grade-by-thickness (eU × thickness) map has been generated for the Centenario Core Horizon (see Figure 1). The map, which incorporates the 104 integrated wells, confirms the presence of the uranium mineralized zones consistent with roll front style mineralization. The northwestern extent of the uranium mineralized corridor remains open, suggesting potential for further expansion. Additionally, the map highlights a single principal corridor of uranium equivalent anomalies, along which multiple anomalies have been identified. One of these bodies is particularly noteworthy for its scale, measuring approximately 2.2 kilometres along a northwest–southeast trend and 500 metres in width (Figure 2). This data integration supports improved mapping of the uranium-bearing horizon and reinforces the potential for expansion of the uranium mineralized system.
Nikolaos Cacos, President & CEO of the Company, stated, “The quality of the newly integrated data significantly improves our confidence in the continuity and scale of the uranium system at Corcovo. The Centenario Core horizon now shows potential for an even more extensive uranium mineralized system, and we are prioritizing the acquisition and interpretation of 3D seismic data to help delineate the geometry of the potential mineralized bodies. These are key steps in our process to advance the project in support of a potential resource estimation in the future.”
Deposit Model
The Inkai uranium project in Kazakhstan is one of the world-leading ISR mining projects and a model for exploration at Corcovo. This roll-front uranium mineralization is hosted in permeable Cretaceous fluvial sandstones, with mineralized zones located at depths of 350 to 530 metres. Individual orebody thicknesses range from 2 to 10 metres, with localized zones reaching up to 15 metres. A characteristic of Inkai is the continuity and scale of the mineralization: roll-front horizons are laterally extensive, commonly traceable for over 25 kilometers in length and up to hundreds of metres in width. These dimensions, combined with favorable porosity and permeability, support efficient and sustained ISR operations. The deposit averages approximately 0.03% U₃O₈ and contains proven and probable reserves totaling 368 million tonnes with 251 million pounds of U₃O₈ (www.cameco.com 06/02/2025).
Planned Activities and Data Acquisition
Blue Sky Uranium recently secured a historic subsurface dataset comprising data from several hundred O&G wells and 34 2D seismic lines. To date, the Company has processed and integrated 104 of these drillholes into its geological model. This initial integration has provided valuable insights into the Centenario Core horizon and has helped delineate the principal uranium-equivalent mineralized corridor.
The technical team is currently working to incorporate the remaining 344 historical drill holes, which will further enhance the geological and mineralization model. In parallel, the Company is actively pursuing access to 3D seismic data. This expanded effort will improve resolution of subsurface structures and stratigraphy especially throughout the northwestern section of the corridor, which remains open.
