Jaguar Uranium Corp. reports news related to uranium exploration, project evaluation, permitting, and critical-minerals activity across its South American portfolio. Company updates have covered the Berlin Project in Colombia, the Laguna Salada asset and Guanaco property area in Argentina, the historic Huemul Uranium Mine, and rare earth element assessment work tied to historical mineral data.
Recurring developments also include conference participation, collaboration arrangements with government authorities, environmental approvals, exploration strategy updates, and capital-structure matters following the company's public listing on the NYSE American.
Jaguar Uranium (JAGU) filed its maiden independent mineral resource estimate for the Laguna Salada uranium-vanadium project on October 19, 2026. The project in Chubut Province, Argentina, is 100%-owned. The U.S. S-K 1300 and Canadian NI 43-101 technical reports have an effective date of October 5, 2026, with no material differences from results disclosed on October 13, 2026.
Jaguar Uranium (JAGU) announced an independent maiden mineral resource estimate for its wholly owned Laguna Salada uranium-vanadium project in Argentina. Effective October 5, 2026, the estimate contains 4.2 million pounds of indicated uranium oxide and 10.1 million pounds inferred, alongside 31.1 million and 57.3 million pounds of vanadium pentoxide, respectively. Indicated resources total 21.1 million tonnes at 90 parts per million uranium oxide; inferred resources total 34.0 million tonnes at 137 parts per million.
The resource footprint covers approximately 4.3% of the project. Jaguar targets approximately 250 new pits and trenches, 1,500 metres of sonic/vibrosonic drilling, and metallurgical and environmental studies. Resources use a $12.08-per-tonne net smelter return cut-off, reflecting estimated value after recovery and selling costs. Mining and processing methods and economic viability remain unestablished. Jaguar holds nearly US$18 million in cash and no debt.
Jaguar Uranium (JAGU) announced its maiden independent mineral resource estimate for the wholly owned Laguna Salada uranium-vanadium project in Argentina.
Effective October 5, 2026, the estimate reports 21.1 million tonnes of Indicated resources containing 4.2 million pounds of uranium oxide and 31.1 million pounds of vanadium oxide. Inferred resources total 34.0 million tonnes, containing 10.1 million pounds and 57.3 million pounds, respectively. Uranium-equivalent grades, incorporating vanadium value, are 119 parts per million for Indicated resources and 170 for Inferred resources.
The resource footprint covers approximately 4.3% of the project. Jaguar targets approximately 250 additional pits and trenches and 1,500 metres of sonic/vibrosonic drilling to upgrade and expand resources. It holds nearly US$18 million in cash with no debt. Mining and processing methods and costs require further technical studies.
Jaguar Uranium (JAGU) reported a final uranium assay of 4.21% U₃O₈ from selective surface sampling at its Huemul project in Argentina. Reanalysis of outcrop composite sample 4319 returned the result, equivalent to 3.57% uranium, after exceeding the laboratory’s reporting limit. Updated results also include copper up to 8.54%, silver up to 708 g/t and vanadium oxide up to 2.27%.
Surface occurrences define an exploration corridor greater than four kilometres long, but have not been demonstrated to form a continuous mineralized zone. Jaguar is using the results to evaluate targets as it considers a potential maiden drill campaign. Selective sampling of visible mineralization may bias grades upward; sample 4319 does not represent a channel width or establish average grade or continuity. The independent technical reviewer has not made a current site visit or physically verified sampling procedures.
Jaguar Uranium (JAGU) received environmental impact assessment approval for exploration at La Rosada, part of its Laguna Salada project in Argentina.
The approval from Chubut Province's Ministry of Environment authorizes exploration across six properties totaling 59,895.3 hectares, approximately 25% of Laguna Salada's approximately 230,000 hectares. The properties comprise La Rosada and Horqueta 1 through Horqueta 5. La Rosada lies 45 kilometers northeast of Guanaco, another Laguna Salada prospect that received environmental approval earlier in 2026.
Jaguar plans to begin prospecting after the winter season ends. Its planned work includes geochemical sampling, geological mapping, radiometric grid surveys and electrical resistivity tomography.
Jaguar Uranium (JAGU) will participate in ROTH Capital Partners' Emerging Nuclear Technology Conference in New York City on October 1, 2026. Management plans to discuss exploration progress across its four wholly owned uranium, rare earth and copper assets in Argentina and Colombia, along with its exploration strategy and 2027 plans.
Jaguar Uranium (JAGU) reported rare earth oxide assays from retained historical drill core at its Berlin project in Colombia on September 24, 2026.
A selected DDB-041 interval measured 0.63 metres at 3,570 parts per million (ppm) total rare earth oxides (TREO) and 607 ppm magnet rare earth oxides (MREO). It had the highest TREO grade among the reported intervals. DDB-003 returned 1.53 metres at 2,267 ppm TREO and 329 ppm MREO; DDB-068 returned 0.50 metres at 2,532 ppm TREO and 414 ppm MREO.
The core was drilled between 2010 and 2012. The tested intervals were selected from available retained core, not systematically sampled across the mineralized horizon; their true widths are undetermined. These are exploration results, not a mineral resource or reserve. Economic viability and metallurgical recovery have not been established. Jaguar plans to assess whether further technical work supports including the results in future geological modelling and resource work.
Jaguar Uranium (NYSE-AM: JAGU) reported final copper assay results from its initial rock sampling program at the Huemul uranium-copper-vanadium project in Malargüe, Mendoza, Argentina. Selective surface samples returned copper grades up to 8.54% Cu, uranium up to 2.27% U (22,700 ppm, with one sample >25,000 ppm pending), silver up to 708 g/t Ag, and vanadium up to 1.27% V.
Sampling along the Uryco/Rosa and Black zone trends indicates a potential 4 km corridor of copper mineralization exposed at surface, with mapped strike lengths of approximately 2,200 m (Uryco-Rosa), 1,300 m (Black Zone) and 2,300 m (Vega Larga). Jaguar is planning a maiden drill campaign to test these targets. According to the company, QA/QC checks using blanks and duplicates were satisfactory, though sampling is selective and does not establish mineral resources or reserves, and a qualified person has not yet conducted a current site visit.
Jaguar Uranium (NYSE American: JAGU) reported final copper assay results from its initial surface rock and channel sampling at the Huemul uranium‑copper‑vanadium project in Mendoza, Argentina. Selective samples returned up to 8.54% Cu, uranium up to values reported as >25,000 ppm, silver up to 708 g/t and vanadium up to 1.27%.
Sampling along the Uryco/Rosa and Black Zone trends has outlined a potential 4‑km corridor of copper mineralization exposed at surface, while Huemul Mine / Agua Botada appears more uranium‑vanadium dominant. Jaguar used accredited ALS Mendoza for assays with blanks and duplicates, and the qualified person considers QA/QC results satisfactory.
The company stresses that sampling targeted visible mineralization and may be biased, so results do not establish mineral resources or reserves. Jaguar is advancing toward a maiden drill campaign at Huemul, a historic district anchored by Argentina’s first producing uranium mine, and follows its US$25 million NYSE American IPO completed in February 2026.
Jaguar Uranium (NYSE:JAGU) has engaged Manifest Industries as its strategic advisor for U.S. government relations and appointed retired U.S. Army General Charles Flynn as an advisor. Manifest will help Jaguar identify and engage U.S. agencies and Armed Services supply and logistics entities relevant to the company’s uranium exploration objectives.
Jaguar’s projects are focused on uranium exploration in Argentina and Colombia, which management views as aligned with U.S. efforts to secure critical minerals from allied countries, as the U.S. mobilizes over $30 billion for critical mineral supply chains. The company emphasizes its assets are at the exploration stage, with no current mineral resources or reserves and no assurance of advancement to development or production.
