Jaguar Uranium Finds Surface Uranium-Copper-Vanadium at Huemul; Assays Pending
- Visible Uranium-Copper-Vanadium mineralization observed at surface, consistent with historical head grades of 0.21% Uranium, 2.0% Copper and 0.11% Vanadium1
- Potential 4-kilometre copper trend identified; historic mine dumps sampled for first time
- 200 rock samples completed at Huemul Uranium-Copper-Vanadium Project, Malargüe Department, Mendoza, Argentina; assays pending
- Project underpinned by U.S.–Argentina Critical Minerals Framework and formal Mendoza provincial Collaboration Agreement (2026)
TORONTO, June 2, 2026 /CNW/ - Jaguar Uranium (NYSE American: JAGU) is pleased to announce the successful completion of its initial 200-sample 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 indicating potential new mineralized areas across the more than 27,000-hectare district-scale project.
________________________ |
1 Visible 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. |
Program Highlights
The field team collected 200 rock samples spanning the project's most prospective targets. Field observations to date appear generally consistent with the presence of mineralization described in historical reports.
Near the former Huemul mine itself, the team identified and sampled two outcrops exhibiting visible uranium and copper mineralization consistent with historic records. In addition, historic mine dumps were assessed for the first time and appear, based on visual inspection and historical data, to contain uranium, copper and vanadium mineralization, representing a previously unsampled area warranting further evaluation.2
In the southern part of the project, field observations indicate the presence of mineralization at multiple locations on the ground. Most notably, sampling of strike extensions at the Uryco zone identified a potential 4-kilometre-long trend of copper mineralization in outcrop, consistent with the scale of the system suggested by historical work.3
Assay results from the 200 samples are pending. All mineralization observations described herein are based on visual field assessment and historical data and remain subject to laboratory verification.

2 No conclusions can be drawn regarding grade, continuity, or economic potential pending receipt of assay results and further analysis. |
3 These observations are preliminary and do not establish continuity of mineralization between occurrences. |
A District with Proven Historical Production
The Huemul Project is anchored by Argentina's first-ever producing uranium mine, commissioned in 1955 and operated continuously until 1975 by the Comisión Nacional de Energía Atómica (CNEA). Historical records document approximately 130,000 tonnes of ore processed at the Malargüe plant, with head grades averaging 0.21% uranium, 2.0% copper, and 0.11% vanadium. The project hosts uranium-copper-vanadium mineralization in a classic sandstone-hosted deposit setting. The broader Malargüe Mining District remains largely untested by modern exploration methods. Based on the presence of a former producing mine, historical exploration data, and the extent of the Company's land package, management believes the project warrants further systematic exploration.
A Jurisdiction on the Rise
Mendoza Province is undergoing a landmark transformation in its approach to mining development, positioning itself as one of Argentina's most compelling emerging mining jurisdictions.4 5 The Malargüe department within Mendoza has long been recognized as a pro-mining area with a distinct history of mineral development, including uranium, vanadium, copper, and hydrocarbons.6 7 The Company has formalized its relationship with the provincial government through a Collaboration Agreement with the Ministry of Energy and Environment of the Province of Mendoza, signed March 4 2026, establishing government-to-company cooperation across its Mendoza properties. This agreement, combined with the U.S.–Argentina Framework Instrument for Securing Critical Minerals Supply signed in February 2026, positions Huemul squarely within the critical minerals supply strategies of both nations. The Company believes these developments may provide a supportive policy backdrop for Argentinean critical minerals projects such as Huemul.

Management Commentary
"The visible mineralization we observed in outcrop and in the historic mine dumps is generally consistent with descriptions in historical records that first drew us to Huemul, and the potential 4-kilometre copper trend at Uryco aligns with what historical data suggested. We look forward to receiving assay results to validate these observations as we plan our next phase of work." said Steven Gold, President & Chief Executive Officer
