Jaguar Uranium Corp. Finds Surface Uranium-Copper-Vanadium At Huemul Jaguar Uranium announce the successful completion of its initial 200-sample rock sampling program at the Huemul Uranium-Copper-Vanadium (U-Cu-V) Project, located in Malargüe, Mendoza Province, Argentina. The two-week field campaign delivered encouraging early observations, consistent with previously documented mineralization and indicating potential new mineralized areas across the more than 27,000-hectare district-scale project. The field team collected 200 rock samples spanning the project's most prospective targets. Field observations to date appear generally consistent with the presence of mineralization described in historical reports. Near the former Huemul mine itself, the team identified and sampled two outcrops exhibiting visible uranium and copper mineralization consistent with historic records. In addition, historic mine dumps were assessed for the first time and appear, based on visual inspection and historical data, to contain uranium, copper and vanadium mineralization, representing a previously unsampled area warranting further evaluation.2 In the southern part of the project, field observations indicate the presence of mineralization at multiple locations on the ground. Most notably, sampling of strike extensions at the Uryco zone identified a potential 4-kilometre-long trend of copper mineralization in outcrop, consistent with the scale of the system suggested by historical work.3 Assay results from the 200 samples are pending. All mineralization observations described herein are based on visual field assessment and historical data and remain subject to laboratory verification. The Huemul Project is anchored by Argentina's first-ever producing uranium mine, commissioned in 1955 and operated continuously until 1975 by the Comisión Nacional de Energía Atómica (CNEA). Historical records document approximately 130,000 tonnes of ore processed at the Malargüe plant, with head grades averaging 0.21% uranium, 2.0% copper, and 0.11% vanadium. The project hosts uranium-copper-vanadium mineralization in a classic sandstone-hosted deposit setting. The broader Malargüe Mining District remains largely untested by modern exploration methods. Based on the presence of a former producing mine, historical exploration data, and the extent of the Company's land package, management believes the project warrants further systematic exploration.

Jaguar Uranium Corp Commences Field Activity on Guanaco Concessions Block Jaguar Uranium Corp. commenced field activity on the Guanaco Concessions block on its flagship Laguna Salada Uranium-Vanadium Project in Chubut Province, Argentina. The work program, which follows the Company's March 2, 2026 announcement of Environmental Impact Assessment approval from the Province of Chubut, is designed to lay the groundwork for a potential future Mineral Resource Estimate on the Guanaco concessions in the near term.

Jaguar Uranium Corp Initiates Exploration Plan At Huemul Project Jaguar Uranium Corp. announced the formal initiation of its initial exploration plan at the Huemul Project -- a 27,700-hectare uranium-copper-vanadium district in Mendoza Province, Argentina, centered on Argentina's first-ever producing uranium mine. 130,000 tonnes processed over 20 years with historic head grades of 0.21% uranium, 2.0% copper, and 0.11% vanadium highlight the polymetallic nature of the district. The Huemul Project is a 27,000 Ha district-scale, exploration and former operating property in the mining-friendly Malargue area in the Province of Mendoza. The project is anchored by the historic Huemul mine, commissioned in 1955 and operated continuously until 1975 by Argentina's Comisión Nacional de Energía Atómica (CNEA), with approximately 130,000 tonnes of ore processed at the Malargue plant. Historic head grades of 0.21% uranium, 2.0% copper, and 0.11% vanadium highlight the polymetallic nature of the district. The project hosts uranium-vanadium-copper mineralization in a classic sandstone-hosted deposit setting and is a globally recognized model associated with substantial uranium endowment, alongside multiple additional exploration prospects across the claim package that have never been tested with modern methods. Jaguar has designed a multi-phase initial exploration program to systematically advance the Huemul Project, following completion of the baseline study submission. Phase I -- Data Verification & Geological Model: Rigorous check sampling and systematic review of all historic trench data from previous operators; desktop geological model compilation to establish an accurate baseline for modern resource estimation. Phase II -- District-Scale Prospecting: Surficial mapping and prospecting across the full claim package to confirm and delineate the extent of uranium-copper-vanadium mineralization, guided by Phase I results and the geological model. Exploration activity is expected to commence following submission and acceptance of the environmental baseline study, subject to receipt of applicable regulatory approval.
