Jaguar Uranium Corp. has returned final assay results from its initial rock sampling program at the Huemul Uranium-Copper-Vanadium Project in Mendoza Province, Argentina, highlighted by copper grades reaching up to 8.54%.

The sampling program, which targeted areas of visible surface mineralization across the district-scale property, also delivered peak values of up to 2.27% uranium, 708 g/t silver, and 1.27% vanadium. Work along strike extensions of the Uryco/Rosa and Black zone trends identified a potential 4-kilometre-long trend of copper mineralization exposed at surface. One over-limit sample result for uranium exceeding 25,000 ppm remains pending reanalysis.

The Huemul Project is anchored by Argentina’s first-ever producing uranium mine, which operated continuously from 1955 to 1975 under the Comisión Nacional de Energía Atómica and processed approximately 130,000 tonnes of mineralized material. Building on this historic activity, Jaguar entered into a non-exclusive framework collaboration agreement with the Ministry of Energy and Environment of the Province of Mendoza on March 4, 2026, to cooperate on technical, environmental, and legal studies.

“These results reinforce what drew us to Huemul in the first place. Copper grades as high as 8.54%, paired with strong uranium and vanadium values across multiple target areas, support our view that this historic district has considerable exploration potential. We're moving quickly toward a maiden drill campaign to test these targets at depth”

— Steven Gold, President & Chief Executive Officer

Jaguar Uranium is planning its maiden drill campaign to test these surface exploration targets at depth across the property.
