# Jaguar Uranium Reports Preliminary Surface Sampling Results from Huemul Uranium-Copper-Vanadium Project *2026-07-20T06:50:00-04:00* Jaguar Uranium Reports Preliminary Surface Sampling Results from Huemul Uranium-Copper-Vanadium Project Canada NewsWire 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% vanadium1. - 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% vanadium2. - A potential 4-kilometre copper trend was identified, and historic mine dumps were sampled for first time. TORONTO, July 20, 2026/CNW/ -- **Jaguar Uranium Corp. **(NYSE-AM: JAGU)**("Jaguar")**is pleased to announce preliminary assay results from its initial 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 indicated potential new mineralized areas across the more than 27,000-hectare district-scale project. | _________________________________ 1Because sampling was selective and targeted areas of visible mineralization, the results may be biased high and should not be considered representative of grade distribution, continuity or mineralization across the Huemul Project. | | --- | | 2Visible uranium-copper-vanadium-bearing mineralization has been observed at surface at certain locations. These observations are qualitative in nature. Historical records for the Huemul project report average head grades of approximately 0.21% uranium, 2.0% copper and 0.11% vanadium; however, the Company has not verified these historical results, and there is no assurance that current mineralization is consistent with such historical grades. | **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](https://edge.prnewswire.com/c/link/?t=0&l=en&o=4734485-1&h=1827586998&u=https%3A%2F%2Fjaguaruranium.com%2Fjaguar-uranium-finds-surface-uranium-copper-vanadium-at-huemul-assays-pending%2F&a=here). Samples were collected from eight target areas, namely, Huemul Min, Agua Botada, Uryco, Rosa, Vega Larga, Black Zone, Cerro Mirano and Lucy (Figure 1). 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 below. The 100 ppm U reporting threshold used for Table 1 is an exploration reporting threshold selected by the Company and should not be interpreted
