Jaguar Uranium Corp. Reports Final Copper Assay Results Including Up To 8.54% Copper And Identifies Potential 4-Km Trend From Huemul Uranium-Copper-Vanadium Project
Jaguar Uranium Corp. announced final assay results for copper from its initial rock sampling program at the Huemul Uranium-Copper-Vanadium (U-Cu-V) Project, located in Malargüe, Mendoza Province, Argentina across the more than 27,000-hectare district-scale project. Channel and rock chip samples from areas of visible uranium-copper-vanadium mineralization observed at surface returned final assay results for copper (up to 8.54%), uranium (up to 2.27%), silver (up to 708 g/t) and vanadium (up to 1.27%). Sampling of strike extensions along the Uryco/Rosa and Black zone trends has identified a potential 4-kilometre-long trend of copper mineralization exposed at surface. One over-limit sample result for uranium (>25,000 ppm) is still pending. 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. Jaguar conducted targeted sampling included outcrop, subcrop, rock chip composite, channel and float samples, across areas of visible surface mineralization. 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 Mine, Agua Botada, Uryco, Rosa, Vega Larga, Black Zone, Cerro Mirano and Lucy. Channel samples were collected over intervals ranging from 50 cm to 280 cm. All 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 included 6 Blanks and 6 Duplicates as part of the sample submission (200 samples in total) for QA/QC assessment. Blank material performed satisfactorily. Two duplicate samples did not compare well and were subsequently re-analysed. The re-analysis confirmed the original assay values for those samples. The QP considers the QA/QC results satisfactory, and the assay results suitable for disclosure. Since the sampling of visible mineralization is selective by nature, the exploration results disclosed in this news release are potentially biased and do not establish the extent and continuity of grade, tonnage, economic significance, mineral resources or mineral reserves of the Huemul Project. Most notably, sampling of strike extensions at the Uryco/Rosa and Black zone trend identified a potential 4-kilometre trend of copper mineralization observed in outcrop, consistent with the scale of the system suggested by historical work. Selected significant results from the surface sampling with U grades greater than 100 ppm or Cu grades greater than 1.0% are presented in Table 2 below. The 100 ppm U and 1.0% Cu reporting thresholds used for Table 2 are exploration reporting thresholds selected by the Company and should not be interpreted as a cut-off grade, economic threshold, or indication of mineral resources or mineral reserves. Mineralization is hosted in the Diamante Formation sandstones, conglomerates, shales and volcano-clastics striking north south and dipping 20-25° to the west in the north and becoming flat lying to the south. Recent sampling results appear show the dominance of U over Cu in this area. The Cerro Mirano, Uryco-Rosa, Black Zone and Vega Larga areas are dominated by Cu-U-V±Ag mineralization. Mapping, rock sampling and gamma surveying have delineated the Uryco-Rosa, Black Zone and Vega Larga target areas, with apparent strike lengths of approximately 2,200 m, 1,300 m and 2,300 m, respectively, hosted along conglomerate and sandstone horizons of the Diamante Formation that collectively define a greater than 4 km corridor of mineralized occurrences. The Cerro Mirano mineralized zone is related to the intrusion of andesitic dikes and is approximately 300 m long. Recent sampling results appear to show the dominance of Cu over U in this area. Over-limit samples for copper (indicated as >25000) were re-analysed by ALS using 4 acid digest and ICP finish (ME-OG62™). One over-limit sample for uranium (indicated as >25000) is being re-analysed using XRF for base metal ores by fusion (ME-XRF15b™) and is still pending. Duplicate re-analysis confirmed the original assay results that were received and indicates a potential sample swap, either during project preparation, or at the laboratory. In the opinion of the QP, these issues are not material at this stage of the project but will need closer attention during further work phases. 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.
