(High)

(Neutral)

Rhea-AI Summary

Jaguar Uranium (NYSE-AM: JAGU) reported preliminary assay results from its initial rock chip and channel sampling program at the Huemul uranium-copper-vanadium project in Malargüe, Mendoza, Argentina. From 200 submitted samples, selective surface sampling returned uranium values up to 22,700 ppm, copper values above the 25,000 ppm upper detection limit (with over-limit reanalysis pending), silver up to 708 g/t and vanadium up to 1.27%.

Samples were collected across eight target areas and identified a potential 4-kilometre copper mineralization trend at Uryco/Rosa. Jaguar highlighted that sampling targeted visible mineralization and may be biased high, results are preliminary exploration data only, and no mineral resources or reserves are established. QA/QC included blanks and duplicates; two duplicates require reanalysis. A qualified person has reviewed the data but has not yet visited the site.

Key Terms

over-limit reanalysis, qa/qc, iso/iec 17025, ni 43-101

4 terms

over-limit reanalysis technical

"with over-limit reanalysis pending"

A laboratory process that retests biological or chemical samples whose initial measurement exceeded an assay’s validated upper limit, using dilution or an alternative method to obtain an accurate numeric result. It matters to investors because it affects the reliability of clinical data, diagnostic claims and regulatory filings—similar to swapping a too-short ruler for a longer one to get the true measurement of an object.

qa/qc technical

"as part of its QAQC program"

QA/QC stands for Quality Assurance and Quality Control, processes used to ensure products or services meet certain standards. Think of it as a way to check that a product is safe and works properly before reaching consumers, similar to how a chef tastes food before serving it. For investors, strong QA/QC practices indicate a company's commitment to delivering reliable, high-quality offerings, reducing risks and building trust.

iso/iec 17025 technical

"is ISO/IEC 17025 accredited sample preparation"

An internationally recognized accreditation for testing and calibration laboratories that confirms they produce reliable, traceable results and follow consistent quality controls. Think of it like a professional license for labs: it shows their methods, equipment and staff competence meet independent standards, which matters to investors because accredited test data lowers technical and regulatory risk, supports product claims, and can speed approvals, supplier selection, and market trust.

ni 43-101 regulatory

"under NI 43-101 or Subpart 1300 of Regulation S-K"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

Channel and rock chip samples from areas of visible uranium-copper-vanadium mineralization observed at surface returned preliminary assay results, including values above the upper detection limit of 25,000 ppm for uranium and copper, with over-limit reanalysis pending, as well as maximum reported values of 708 g/t silver and 1.27% vanadium¹.

Certain samples exceeded the upper detection limit of the analytical method for U and Cu; final over-limit results are pending; therefore, the reported grades should not be considered final.
Samples were taken from areas of visible uranium-copper-vanadium mineralization observed at surface, in areas where historical records report average head grades of 0.21% uranium, 2.0% copper and 0.11% vanadium².
A potential 4-kilometre copper trend was identified, and historic mine dumps were sampled for first time.

TORONTO, July 20, 2026 /PRNewswire/ -- Jaguar Uranium Corp. (NYSE-AM: JAGU) ("Jaguar") is pleased to announce preliminary assay results from its initial 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 indicated potential new mineralized areas across the more than 27,000-hectare district-scale project.

Sampling Program

Jaguar submitted 200 samples, consisting of 188 channel and rock chip samples with 6 Blanks and 6 Duplicates, spanning the project's most prospective targets. Field observations were generally consistent with the presence of mineralization described in historical reports, particularly around the former Huemul mine, as described previously here.

____________________________

¹ Because sampling was selective and targeted areas of visible mineralization, the results may be biased high and should not be considered representative of grade distribution, continuity or mineralization across the Huemul Project.

² 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.

Samples were collected from eight target areas, namely, Huemul Min, Agua Botada, Uryco, Rosa, Vega Larga, Black Zone, Cerro Mirano and Lucy (Figure 1). Most notably, sampling of strike extensions at the Uryco/Rosa zone identified a potential 4-kilometre trend of copper mineralization observed in outcrop, consistent with the scale of the system suggested by historical work.

Figure 1: Huemul Project Target and Surface Sampling Locations

Targeted sampling included outcrop and subcrop float, select, chip, composite and channel samples collected from areas of visible surface mineralization. Since visible mineralization was targeted, the results may be biased high and should not be considered representative of grade distribution across the project. Channel samples were collected over intervals ranging from 50 cm to 280 cm. Samples were packaged and sealed at the project site by Jaguar geologist and transported to ALS in Mendoza, Argentina for analysis using sodium peroxide decomposition method ME-MS89L™. ALS Mendoza is a full-service laboratory and is ISO/IEC 17025 accredited sample preparation and geochemical analysis. ALS Mendoza is independent of Jaguar.

Jaguar inserted six blanks and six duplicate samples as part of its QAQC program. Blank material performed satisfactorily, but two of the duplicates did not compare well. These samples will be reanalysed, but the QP considers the current preliminary disclosure suitable notwithstanding those discrepancies. The results disclosed in this news release are preliminary exploration results and do not establish the extent, continuity, grade, tonnage, economic significance, mineral resources or mineral reserves of the Huemul Project.

Selected significant results from the surface sampling with U grades greater than 100 ppm are presented in Table 1 below. The 100 ppm U reporting threshold used for Table 1 is an exploration reporting threshold selected by the Company and should not be interpreted as a cut-off grade, economic threshold, or indication of mineral resources or mineral reserves. A full tabulation of the sample coordinates, sample types and assay results is reported in Appendix 1.

Notes:

ppm = g/t
10,000 ppm = 1.0%
Values reported as '>25,000 ppm' exceed the upper detection limit and are subject to over-limit reanalysis; final values may differ.

Over-limit samples for uranium and copper (indicated >25000) are to be re-analysed by ALS using XRF for base metal ores by fusion (ME-XRF15b™) and will be reported once they become available.

Rock chip and channel samples are selective by nature and may not be representative of mineralization across the property. Reported sample results should be considered preliminary exploration results and do not establish the extent, continuity, or economic significance of mineralization.

Data Verification

The QP's review of the sampling, analytical and QA/QC information disclosed in this news release was limited to a review of information provided by the Company and its consultants, including sample locations, sample descriptions, analytical certificates, analytical methods and QA/QC results. The QP has not completed a current site visit to the Huemul Project and has not independently observed or physically verified the sampling procedures, sample locations, sample security or chain-of-custody procedures. The QP has not independently verified the historical production, historical grade or historical exploration information referenced in this news release. The QP's review is subject to the limitations described herein, including the selective nature of the samples, pending over-limit reanalysis for certain uranium and copper results, and pending follow-up review of duplicate samples that did not compare well.

A District with Documented 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 report that approximately 130,000 tonnes of mineralized material, historically described as ore, were processed at the Malargüe plant, with reported average head grades of 0.21% uranium, 2.0% copper and 0.11% vanadium (source: Guillermo Rojas, 1999. Distrito Uranìfero Pampa Amarilla, Mendoza. En Recursos Minerales de la Republica Argentina. Pag.1135-1140). The Company has not independently verified the historical production records or historical head-grade information, and such information should not be interpreted as current exploration results, a mineral resource estimate, a mineral reserve estimate or evidence of current economic viability.

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.

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 adds district-scale uranium and copper potential to the asset. We look forward to receiving further assay results to validate these observations as we plan our next phase of work, including a targeted drill program to further understand and potentially expand the Huemul project." said Steven Gold, President & Chief Executive Officer

FAQ

What did Jaguar Uranium (JAGU) report in its July 20, 2026 Huemul sampling results?

Jaguar Uranium reported preliminary surface sampling results showing high uranium, copper, silver and vanadium values at Huemul. According to Jaguar Uranium, selective rock chip and channel samples returned uranium up to 22,700 ppm, copper above 25,000 ppm, silver 708 g/t and vanadium 1.27%, pending over-limit reanalysis.

How high were the uranium and copper grades in Jaguar Uranium’s Huemul samples (JAGU)?

The highest reported uranium value was 22,700 ppm, while some copper assays exceeded 25,000 ppm, the method’s upper detection limit. According to Jaguar Uranium, these over-limit uranium and copper samples will be reanalysed using XRF methods, so final grades may differ from current preliminary values.

What is the potential 4-kilometre copper trend announced by Jaguar Uranium (JAGU) at Huemul?

Jaguar Uranium identified a potential 4-kilometre copper trend at the Uryco/Rosa zone based on surface sampling. According to Jaguar Uranium, sampling of strike extensions in this area revealed copper mineralization in outcrop, consistent with the large-scale system suggested by historical work at the Huemul project.

Do Jaguar Uranium’s July 2026 Huemul results establish NI 43-101 mineral resources for JAGU?

No, the Huemul sampling results do not establish mineral resources or reserves under NI 43-101 or Subpart 1300. According to Jaguar Uranium, these rock chip and channel assays are preliminary exploration results and may not be representative of mineralization or economic viability across the property.

How many samples did Jaguar Uranium collect in the Huemul surface program and where?

Jaguar Uranium collected 200 samples, including 188 channel and rock chip samples, from eight target areas at Huemul. According to Jaguar Uranium, targets included Huemul Min, Agua Botada, Uryco, Rosa, Vega Larga, Black Zone, Cerro Mirano and Lucy within the Malargüe district.

What QA/QC measures did Jaguar Uranium apply to the Huemul sampling program (JAGU)?

Jaguar Uranium implemented QA/QC using six blanks and six duplicate samples in the Huemul program. According to Jaguar Uranium, blank samples performed satisfactorily, but two duplicates did not compare well and will be reanalysed, though the qualified person still considers the preliminary disclosure suitable.

How reliable are the historical Huemul production and grade figures referenced by Jaguar Uranium (JAGU)?

Historical records report about 130,000 tonnes processed at Huemul with specific average grades, but reliability remains uncertain. According to Jaguar Uranium, these historical production and grade figures have not been independently verified and are not being treated as current resources, reserves or exploration results.
