Blue Sky Confirms Uranium Discovery Potential at its ISR Corcovo Project, Argentina

Blue Sky Uranium Corp. (TSXV: BSK) (FSE: MAL2) (OTC: BKUCF) ("Blue Sky" or the "Company") is pleased to announce the results of the initial technical review work completed at the Corcovo Uranium Project, an "in situ" recovery (" ISR ") high potential target in Mendoza Province Argentina . The geological team has reviewed and interpreted bore-hole survey data from 89 historical oil and gas (" O&G ") wells, identifying radiometric anomalies at four different stacked horizons, including significant sections up to 10m in thickness along an open trend of more than 10km long (see Figure 1 ).

Nikolaos Cacos , President & CEO of the Company stated, "This data from Corcovo represents a major step forward towards a potential second significant discovery for our Company. The quality and continuity of the radiometric anomalies support the ISR potential of the region, initially recognized as area prospective for uranium by the National Atomic Energy Commission (" CNEA ") and confirm Corcovo as a promising new target area in our portfolio."

The Corcovo Project covers 20,000 hectares at the northeastern margin of the O&G producing Neuquén Basin. The geological potential of the region for uranium ISR deposits was initially defined by CNEA, the state-owned nuclear company, as reported in the International Atomic Energy Agency and Nuclear Energy Agency document titled: " Uranium 2024: Resources, Production and Demand ". Blue Sky optioned the Corcovo project in 2024 as part of a strategic initiative to broaden the Company's medium to long-term prospects for discovery of additional uranium mineral resources. The project benefits from flat topography, road access, and year-round accessibility, supporting cost-effective exploration and potential future ISR development.

Highlights of the Technical Review:

Blue Sky geologists obtained data for the historical O&G wells via public access request. The data review and interpretation was completed for 89 drill holes for which gamma-ray, density, and self-potential (" SP ") logs were obtained and provided strong geological control. Thirty wells detected (" Ueq ") (see Table 1). Four discrete uranium-bearing intervals were identified in fluvial and channelized sandstones, including:

• Centenario Formation Core: 500–600m* depth, most continuous and highest-grade target identified based on the data available to date
  
  
• Centenario Formation Edge: 500–550m* depth, transitional zone, isolated intercepts up to 60 ppm Ueq in less continuous horizon
  
  
• Neuquén Horizon: 300–400m* depth, shallowest zone with continuous sandstone layers, preliminary Uranium equivalent values range between 25–65 ppm.
  
  
• Rayoso Channel: 450–500m* depth, interpreted paleo-channel fill, shows Ueq anomalies ranging from 30–80 ppm.

The Centenario Formation Core is the main target, where prospective radiometric anomalies between 1 and 10m thickness were detected, with values up to 261 ppm Ueq (0.03 U ₃ O ₈ eq; drill hole JCP-1002, @ 560.30m and 560.37m ) and estimated porosity values were between 22%–30% (see methodology description below). Uranium equivalent values were obtained directly from calibrated spectral gamma-ray logs, using spectrometric tools with readings approximately every 0.15 to 0.25 metres.

A preliminary Ueq×thickness contour map for the Centenario Formation Core target outlines a potential roll-front morphology along approximately 7km (see Figure 1 , grey dashed line). The estimated porosity indicates potentially favorable conditions for "in situ" recovery production methodologies. In the northwestern zone where the best results to date have been identified, the interpretation is considered preliminary and based on limited historical drillholes.

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

The Company has confirmed the existence of additional subsurface information within the Corcovo area, including a 3D-2D seismic survey and data from approximately 200 historical drill holes with spacing of approximately 330 to 400 metres.  The drill hole information will be particularly valuable in the northwestern sector, where the current drill spacing is generally wider. This additional information will support 3D seismic interpretation to refine the morphology of horizons with anomalous uranium equivalent and their relation to subsurface geologic structures. The process is underway to secure access to this information. In addition, the Company aims to obtain water samples from active oil wells operating under secondary recovery within the property limits, and drill cuttings from historic holes, to validate the historic gamma-ray data and complete geochemical testing.

Methodology and QA/QC

Blue Sky Uranium Corp. obtained oil and gas drilling data for 89 wells from Pluspetrol, for work conducted on the properties between 2006 and 2018 including by its corporate predecessors (see drill hole information in Table 2 ). This data originates from historical oil and gas exploration programs and has not been independently verified by a Qualified Person.

Uranium equivalent values were obtained directly from calibrated spectral gamma-ray logs using NaI(Tl) crystal-based tools, with measurements taken approximately every 0.15 to 0.25 metres. Readers are cautioned that uranium-series disequilibrium may affect radiometric results, potentially leading to either underestimation or overestimation of actual uranium content.

Porosity was estimated using an average derived from three geophysical logs: the neutron log, the compressional sonic log, and the bulk density (" RHOB ") log. This standard petrophysical approach provides a reasonable approximation in the absence of core data. Density values reported are taken from the RHOB profile in historical oil and gas well logs.
