Jaguar Uranium Corp. (NYSE American: JAGU) has released preliminary assay results from an initial rock sampling program at its Huemul Uranium-Copper-Vanadium Project in Malargüe, Mendoza Province, Argentina, according to a company press release.

The two-week field campaign included 200 samples — 188 channel and rock chip samples plus quality control blanks and duplicates — collected across eight target areas. Some samples returned values above the upper detection limit of 25,000 ppm for uranium and copper, with over-limit reanalysis pending. The company reported maximum values of 708 g/t silver and 1.27% vanadium from the targeted samples.

The company noted that sampling was selective and targeted areas of visible mineralization, meaning results may be biased high and should not be considered representative of grade distribution across the project. Two of six duplicate samples did not compare well and are also pending reanalysis. The results do not establish mineral resources or mineral reserves.

Sampling of strike extensions at the Uryco/Rosa zone identified a potential 4-kilometer copper mineralization trend observed in outcrop. Historic mine dumps were sampled for the first time during the campaign.

The Huemul Project covers more than 27,000 hectares and is anchored by Argentina's first uranium mine, which operated from 1955 to 1975. Historical records, unverified by the company, report average head grades of 0.21% uranium, 2.0% copper and 0.11% vanadium from approximately 130,000 tonnes of processed material.

Samples were analyzed by ALS Mendoza, an ISO/IEC 17025 accredited laboratory independent of Jaguar, using sodium peroxide decomposition. The qualified person for the disclosure, George van der Walt of The MSA Group, has not completed a current site visit to the project.

Jaguar completed a $25 million initial public offering on NYSE American in February 2026.
