en.Wedoany.com Reported - Jaguar Uranium has completed the initial collection of 200 rock samples at the Huemul project in the Malargüe district of Mendoza Province, Argentina, a program aimed at verifying and expanding historical information on surface uranium, copper, and vanadium mineralization. The company also reported identifying a potential 4-kilometer copper mineralization trend in the Urico area, and is currently awaiting laboratory results to determine the next phase of exploration work.
The two-week field campaign was conducted at the Huemul project, which covers over 27,000 hectares in the Malargüe district. Work included rock sampling at multiple priority targets within the mining concession, mapping of mineralized outcrops, and assessment of historical areas associated with past mining operations.
The company stated that preliminary field observations are generally consistent with the project's historical records, which indicate average grades of approximately 0.21% uranium, 2.0% copper, and 0.11% vanadium. However, Jaguar Uranium emphasized that these historical data have not been verified according to current reporting standards and still require confirmation through laboratory analysis.
One of the highlights of the program was the identification of visible uranium and copper mineralization in several outcrops near the former Huemul mine, as well as sampling of historical waste rock dumps, which, based on visual inspection and previous records, contain uranium, copper, and vanadium mineralization.
The company stressed that no conclusions can be drawn regarding continuity, grade, or economic potential until assay results are received and further technical analysis is completed.
As part of the program, Jaguar Uranium also advanced work in the Urico area, located in the southern portion of the project. The company reported that strike extension sampling identified a potential copper mineralization trend approximately 4 kilometers long. According to Jaguar Uranium, field observations are consistent with the scale previously suggested by historical work and support the concept of a broader mineralized system within the concession. The project remains in an early exploration stage, with no drilling activities yet included; current work focuses on surface geochemical verification and the definition of future exploration targets.
The core of the Huemul project is Argentina's first uranium production mine. The mine began operations in 1955 and continued until 1975, managed by the National Atomic Energy Commission (CNEA). Historical records cited by the company indicate that approximately 130,000 tons of ore were processed at the Malargüe beneficiation plant during this period. The concession hosts sandstone-hosted uranium, copper, and vanadium mineralization, which the company believes remains significantly underexplored using modern exploration methods.
Alongside the recently completed sampling program, Jaguar Uranium has initiated a broader exploration strategy for Huemul, conducted in phases over a 12-month technical cycle. The plan includes an estimated investment of $1.1 million and involves prospecting, geophysical surveys, detailed geological mapping, geochemical sampling, and airborne radiometric surveys using drones equipped with gamma-ray spectrometers, aimed at detecting uranium, potassium, and thorium anomalies. The technical plan also includes integrating all data into a three-dimensional geological model for target generation, as well as a future diamond drilling program of approximately 2,000 meters across an initial 10 drill holes, alongside trenching activities and quality assurance/quality control (QA/QC) protocols. Progress to more intensive exploration phases, including drilling, remains subject to additional environmental and technical requirements determined under the Environmental Impact Statement (DIA), including updates to environmental baseline studies, operational details, and input related to emergency response and road access development.
The advancement at Huemul is also linked to the emerging international landscape surrounding critical minerals. In its statement, the company connected the project to a framework agreement between the United States and Argentina to secure strategic mineral supply chains, as well as a cooperation agreement signed in March 2026 with the Mendoza Ministry of Energy and Environment. According to Jaguar Uranium, Huemul's historical production status may qualify it for future international financing programs for critical minerals, including those supported by the Export-Import Bank (EXIM Bank) and the International Development Finance Corporation (DFC), although these remain subject to evaluation processes. The concession hosts uranium, copper, and vanadium within the same area—three minerals considered strategic for the energy transition and for industrial and nuclear supply chains.
Behind the exploration program is a broader corporate strategy focused on financing early-stage exploration through international capital markets. Jaguar Uranium listed on the NYSE American in February 2026 through a transaction aimed at raising approximately $25 million to accelerate field geological surveys, technical studies, and data generation at historical uranium assets in South America. The structure includes the issuance of approximately 6.25 million Class A shares, along with warrants and other financial instruments, following a model commonly used by junior mining companies to reassess the value of historical assets through exploration and expansion of geological knowledge.
Within this strategy, Mendoza Province plays a central role. In addition to Huemul, Jaguar Uranium is also targeting Sierra Pintada, the country's last uranium production district, seeking a foothold in areas with production history, existing infrastructure, and long-standing ties to Argentina's nuclear industry. While assay results are still pending, the initial activities at Huemul have allowed Jaguar Uranium to complete the first surface verification program at one of Mendoza Province's historical uranium districts. The identification of new mineralized zones and a potential 4-kilometer copper trend now begins to define the project's next technical steps: transforming preliminary observations into verifiable geological information.
