Jaguar Uranium Corp.

Toronto – September 29, 2026 -- Jaguar Uranium Corp. (NYSE American: JAGU) has secured Environmental Impact Assessment approval from Chubut Province's Ministry of Environment for the La Rosada prospect, unlocking exploration rights across 59,895.3 hectares in Argentina.

Approval covers a quarter of the entire Laguna Salada project

The permit authorizes exploration activities across six properties totaling 59,895.3 hectares -- approximately 25% of the 230,000-hectare Laguna Salada uranium-vanadium project, the largest single component of the district-scale portfolio to date.

La Rosada sits 45 kilometers from a prospect already cleared this year

The newly permitted zone lies 45 kilometers northeast of the Guanaco prospect, which received its own EIA approval on March 2, 2026, extending Jaguar's cleared exploration footprint within the same project area.

Toronto – September 28, 2026 -- Jaguar Uranium Corp. (NYSE American: JAGU) will present its four-asset South American exploration portfolio at ROTH Capital Partners' inaugural Emerging Nuclear Technology Conference on October 1, 2026, in New York City.

Jaguar holds uranium, rare earth and copper assets across Argentina and Colombia

The company's portfolio spans brownfield and former mining districts, including the Laguna Salada Project in Chubut Province, Argentina, and the historic Huemul uranium mine in Mendoza Province, previously a producing operation. In Colombia, the Berlin Project in Caldas Province is a district-scale, sedimentary-hosted polymetallic system historically reported to contain uranium alongside rare earth elements, vanadium, nickel, phosphate, molybdenum, rhenium and zinc.

Toronto – September 24, 2026 -- Jaguar Uranium Corp. (NYSE American: JAGU) has reported assay results from historical drill-core resampling at its Berlin Uranium–Rare Earth Project in Colombia's Department of Caldas, with one interval returning 3,570 ppm total rare earth oxides (TREO) and 607 ppm magnet rare earth oxides (MREO), the highest value from the tested selection.

Selected core intervals confirm polymetallic mineralization combining uranium, vanadium and phosphate

The resampling program, first announced March 17, 2026, tested core drilled between 2010 and 2012 during two historical campaigns by U3O8 Corp. Beyond the top-grade interval in drill hole DDB-041 (0.63 m at 170.57–171.20 m depth), additional selected intervals returned 1.53 m at 2,267 ppm TREO and 329 ppm MREO in DDB-003, 1.00 m at 2,176 ppm TREO and 349 ppm MREO in DDB-015, and 0.50 m at 2,532 ppm TREO and 414 ppm MREO in DDB-068.
