BATON ROUGE, LOUISIANA (Steve Stewart, Energy Analytics Institute, 4.Jun.2025, Words: 545) — Blue Sky Uranium Corp.’s geological team reviewed and interpreted bore-hole survey data from 89 historical oil and gas wells, identifying radiometric anomalies at 4 different stacked horizons, including significant sections up to 10m in thickness along an open trend of more than 10km long at the Corcovo uranium project, an “in situ” recovery (ISR) high potential target in Mendoza Province, Argentina.
The project covers 20,000 hectares at the northeastern margin of the oil and gas producing Neuquén basin. The geological potential of the region for uranium ISR deposits was initially defined by state-owned nuclear company National Atomic Energy Commission (CNEA) as reported by the International Atomic Energy Agency and Nuclear Energy Agency.
Blue Sky optioned the Corcovo project in 2024 as part of a strategic initiative to broaden its 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, Blue Sky said on 4 Jun. 2025 in an official statement.
“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,” Blue Sky president and CEO Nikolaos Cacos said in the statement.
Technical review highlights
Blue Sky geologists obtained data for the historical oil and gas wells via public access request. The data review and interpretation was completed for 89 drill holes for which gamma-ray, density, and self-potential logs were obtained and provided strong geological control. 30 wells detected (Ueq), while 4 discrete uranium-bearing intervals were identified in fluvial and channelized sandstones, including:
— Centenario Formation Core: 500m–600m depth, most continuous and highest-grade target identified based on the data available to date;
— Centenario Formation Edge: 500m–550m depth, transitional zone, isolated intercepts up to 60 ppm Ueq in less continuous horizon;
— Neuquén Horizon: 300m–400m depth, shallowest zone with continuous sandstone layers, preliminary Uranium equivalent values range between 25m–65 ppm; and
— Rayoso Channel: 450m–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 1m-10m thickness were detected, with values up to 261 ppm Ueq (0.03 U3O8eq; drill hole. Blue SKy has confirmed the existence of additional subsurface information within the Corcovo area, including a 3D-2D seismic survey and data from 200 historical drill holes with spacing of 330m-400m. The drill hole information will be particularly valuable in the northwestern sector, where the current drill spacing is generally wider,” Blue Sky said in the statement.
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, Blue Sky looks 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.
