Jaguar Uranium Reports Preliminary Surface Sampling Results from Huemul Uranium-Copper-Vanadium Project
Jaguar Uranium Corp. submitted 200 samples, consisting of 188 channel and rock chip samples with 6 Blanks and 6 Duplicates, spanning the project's most prospective targets. Channel and rock chip samples from areas of visible uranium-copper-vanadium mineralization observed at surface returned preliminary assay results, including values above the upper detection limit of 25,000 ppm for uranium and copper, with over-limit reanalysis pending, as well as maximum reported values of 708 g/t silver and 1.27% vanadium. Certain samples exceeded the upper detection limit of the analytical method for U and Cu; final over-limit results are pending; therefore, the reported grades should not be considered final. Samples were taken from areas of visible uranium-copper-vanadium mineralization observed at surface, in areas where historical records report average head grades of 0.21% uranium, 2.0% copper and 0.11% vanadium. A potential 4-kilometre copper trend was identified, and historic mine dumps were sampled for first time. Sampling Program Jaguar submitted 200 samples, consisting of 188 channel and rock chip samples with 6 Blanks and 6 Duplicates, spanning the project's most prospective targets. Field observations were generally consistent with the presence of mineralization described in historical reports, particularly around the former Huemul mine, as described previously here. Samples were collected from eight target areas, namely, Huemul Min, Agua Botada, Uryco, Rosa, Vega Larga, Black Zone, Cerro Mirano and Lucy. Most notably, sampling of strike extensions at the Uryco/Rosa zone identified a potential 4-kilometre trend of copper mineralization observed in outcrop, consistent with the scale of the system suggested by historical work. Targeted sampling included outcrop and subcrop float, select, chip, composite and channel samples collected from areas of visible surface mineralization. Since visible mineralization was targeted, the results may be biased high and should not be considered representative of grade distribution across the project. Channel samples were collected over intervals ranging from 50 cm to 280 cm. Samples were packaged and sealed at the project site by Jaguar geologist and transported to ALS in Mendoza, Argentina for analysis using sodium peroxide decomposition method ME-MS89L. ALS Mendoza is a full-service laboratory and is ISO/IEC 17025 accredited sample preparation and geochemical analysis. ALS Mendoza is independent of Jaguar. Jaguar inserted six blanks and six duplicate samples as part of its QAQC program. Blank material performed satisfactorily, but two of the duplicates did not compare well. These samples will be reanalysed, but the QP considers the current preliminary disclosure suitable notwithstanding those discrepancies. The results disclosed in this news release are preliminary exploration results and do not establish the extent, continuity, grade, tonnage, economic significance, mineral resources or mineral reserves of the Huemul Project. Selected significant results from the surface sampling with U grades greater than 100 ppm are presented in Table 1. The 100 ppm U reporting threshold used for Table 1 is an exploration reporting threshold selected by the Company and should not be interpreted as a cut-off grade, economic threshold, or indication of mineral resources or mineral reserves. Over-limit samples for uranium and copper (indicated >25000) are to be re-analysed by ALS using XRF for base metal ores by fusion (ME-XRF15b) and will be reported once they become available. Rock chip and channel samples are selective by nature and may not be representative of mineralization across the property. Reported sample results should be considered preliminary exploration results and do not establish the extent, continuity, or economic significance of mineralization. Data Verification The QP’s review of the sampling, analytical and QA/QC information disclosed in this news release was limited to a review of information provided by the Company and its consultants, including sample locations, sample descriptions, analytical certificates, analytical methods and QA/QC results. The QP has not completed a current site visit to the Huemul Project and has not independently observed or physically verified the sampling procedures, sample locations, sample security or chain-of-custody procedures. The QP has not independently verified the historical production, historical grade or historical exploration information referenced in this news release. The QP’s review is subject to the limitations described herein, including the selective nature of the samples, pending over-limit reanalysis for certain uranium and copper results, and pending follow-up review of duplicate samples that did not compare well. A District with Documented Historical Production 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 report that approximately 130,000 tonnes of mineralized material, historically described as ore, were processed at the Malargüe plant, with reported average head grades of 0.21% uranium, 2.0% copper and 0.11% vanadium. The Company has not independently verified the historical production records or historical head-grade information, and such information should not be interpreted as current exploration results, a mineral resource estimate, a mineral reserve estimate or evidence of current economic viability. 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.
