NordX Historical Drill Core Resampling Confirms 11.3m Grading 0.68% U3O8 Beginning at 21.2m Downhole, at the Riutta Project, Finland

Rhea-AI Summary

NordX Metals (OTCQB: NRDMF) reported assay results from a historical core resampling program at its 100%-owned Riutta uranium project in eastern Finland. The best interval from AREVA drill hole DH1 at the Ristimonttu prospect returned 11.3 m grading 0.68% U3O8 from 21.20–32.50 m downhole, including 3.7 m at 1.52% U3O8 between 28.30–32.00 m, with an estimated true thickness of 8.6 m.

Other new intervals include 2.0 m at 0.20% U3O8 (including 0.5 m at 0.66% U3O8) in AE‑7, 0.85 m at 0.094% U3O8 in DH1, and 2.6 m at 0.17% U3O8 in EP038. According to NordX, anomalous copper and silver were locally present, with assays up to 0.45% Cu and 46 g/t Ag in DH1. A QA/QC program using certified standards, blanks and duplicates at CRS Laboratories Oy (ISO/IEC 17025 accredited) returned results within acceptable limits, supporting assay reliability.

Positive

• 11.3 m at 0.68% U3O8 from 21.2 m, including 3.7 m at 1.52% U3O8, confirms shallow uranium mineralization at Riutta
• Resampling also returned intervals such as 2.6 m at 0.17% U3O8 in EP038 and 2.0 m at 0.20% U3O8 in AE-7
• Anomalous by-products with assays up to 0.45% Cu and 46 g/t Ag in AREVA DH1
• Comprehensive QA/QC program with standards, blanks, and duplicates showed all control samples within acceptable accuracy and precision limits
• Riutta mineralization recorded over 450 m of strike within a larger 3.6 km trend, according to NordX

Negative

• Historical drill and boulder results at Riutta have not been verified by the company’s Qualified Person and should not be relied upon
• NordX has not obtained underlying assay data or methodology from the 2011 Mawson Resources sampling of AREVA DH1
• Only 10 drill holes in the last 38 years have been completed at Riutta, indicating limited recent drilling density

News Explained

Existing holders face no stated ownership or cash-flow change; the disclosure adds exploration evidence whose historical result remains unverified.

NordX reported assay results from resampling historical core at its 100%-owned Riutta uranium project, making this an exploration update rather than a completed development or production event.

For existing common holders, the disclosed change is additional exploration evidence at the project, not a stated change in ownership or cash obligations.

Although the headline calls the interval “confirmed,” NordX says the historical result has not been verified by its Qualified Person and should not be relied upon.

The company says mineralization has been recorded over 450 metres of strike within a larger 3.6-kilometre trend; the historical work comprises 65 drill holes totaling 6,275 metres, with only 10 holes drilled in the last 38 years.

The release also says the underlying assay data and methodology from Mawson's earlier sampling are unavailable, leaving that historical comparison unresolved in the disclosed record.

Vancouver, British Columbia--(Newsfile Corp. - August 5, 2026) - NordX Metals Corp. (CSE: NRDX) (OTCQB: NRDMF) (FWB: 0UL0) ("NordX" or the "Company") is pleased to announce assay results from a historical drill core resampling program confirming significant, shallow uranium mineralization at its 100%-owned Riutta project ("Riutta"), near Joensuu in eastern Finland.

The best result came from the Ristimonttu prospect where drill hole AREVA DH1 intersected 11.3 metres ("m") at 0.68% uranium oxide ("U₃O₈") from 21.20 to 32.50m including 3.7m grading 1.52% U₃O₈ between 28.30 and 32.00m. The estimated true thickness of the interval is 8.6m. AREVA (now Orano) drilled the hole in 2008. The core went unassayed amid the company's global restructuring and a downturn in uranium prices, ahead of the 2010 sale of its Finnish uranium assets to Mawson Resources which subsequently sampled this same interval and reported a historical result in 2011 that is consistent with NordX's result above. This historical result has not been verified by the Company's Qualified Person and should not be relied upon.

Other notable results from the newly sampled intervals include:

• 2m at 0.20% U₃O₈ between 62.80m and 64.80m, including 0.5m at 0.66% U₃O₈ between 63.8m and 64.3m from Atomienergia's drill hole AE-7;

• 1.75m at 0.033% U₃O₈ between 39.75m and 41.5m including 0.6m at 0.07% U₃O₈ between 39.75m and 40.35m from AREVA's drill hole DH2;

• 0.85m at 0.094% U₃O₈ between 5.8m and 6.65m from AREVA drill hole DH1; and

• 2.6m at 0.17% U₃O₈ between 22.2m and 24.8m from Outokumpu drill hole EP038.

Anomalous grades of copper and silver were also identified together with some of the elevated uranium grades with maximum assay values grading up to 0.45% Cu and 46g/t Ag in AREVA DH1 (see Appendix, below).

"This confirms one of the best uranium drill intercepts in Finland's history and demonstrates the potential for highly significant near-surface uranium mineralization at Riutta," said Jon Franklin, NordX President and Director. "Mineralization has been recorded over 450 metres of strike within a larger 3.6 kilometre trend. As such, we are really excited to get to working at Riutta and are looking forward to exploration success."

Riutta Uranium Project History

The Riutta uranium occurrence was discovered in 1958 through radiometric boulder tracing. Four exploration campaigns have followed — Atomienergia (1958-59), Outokumpu Oy (1960-63), the Geological Survey of Finland ("GTK") (1983-88), and AREVA (2008-09) — totalling 65 drill holes across 6,275 m, with only 10 holes drilled in the last 38 years. Over 500 mineralized boulders have been located at Riutta, more than one hundred assaying above 1% uranium, and trenching at the Ristimonttu and Unimonttu prospects has exposed pitchblende veins and pockets. Prior to the newly confirmed AREVA DH1 results, the best previously assayed drill results at Riutta were in drill hole 324, which intersected 3.6m at 1.10% U₃O₈ between 42.00m and 45.60m (including 0.35m at 9.79% U₃O₈ between 42.60m and 42.95m) at the Unimonttu prospect, and in drill hole AE-7 which intersected 1.0 m at 0.35% U₃O₈ between 63.30 m and 64.30m at the Kolmosviuhka prospect, located 260 m and 450 m SSE of drill hole AREVA DH1, respectively (Figure 1). The historical drill results and boulder sampling data referenced above have not been verified by the Company's Qualified Person and should not be relied upon.

Previous historical drill core sampling by Mawson Resources

Mawson Resources sampled and analysed the same AREVA DH1 interval and reported the results in a September 20, 2011 news release. The underlying assay data was later sold, along with the Riutta property, to Tournigan Energy Ltd. in 2012, renamed months later as European Uranium Resources ("EUR"). Most of EUR's claims were subsequently allowed to lapse or were relinquished, and the data was never filed with Finland's Safety and Chemicals Agency ("Tukes"). NordX has not been able to obtain the underlying assay data or methodology.

Riutta Uranium Project Mineralization

Uranium mineralization at Riutta occurs as thin pitchblende veins (up to a few mm wide) infilling fractures and microbreccias within a sericite-quartz schist host. The bedrock comprises Archean granitoids and gneisses overlain by Paleoproterozoic quartzitic metasediments, cut by mafic to ultramafic dykes. Riutta is interpreted as a structurally controlled, low-temperature hydrothermal uranium system, with extensive alteration including epidote, chlorite, quartz, sericite, albite, potassium feldspar, carbonate, and clinozoisite.

Sampling protocol and assay method

Drill core was logged and marked to show where historical core was to be half- or quarter-sampled, in some cases using an automated diamond-blade saw. Cut sections were bagged, assigned sample IDs, and logged in a sample register. Resampling took place at GTK's core archive in Rovaniemi, Finland; samples were then driven personally by NordX geologists to CRS Laboratories Oy in Kempele, near Oulu, for preparation and assay. CRS Laboratories Oy is independent of NordX. Samples were crushed, split, and pulverized under standard procedures, then assayed by four-acid digestion with an ICP-MS finish (method 4A-MS12).

A Quality Assurance/Quality Control (QAQC) program monitored sampling, preparation, and assay quality throughout the resampling campaign, inserting four OREAS certified reference standards, two core duplicates, and one blank into the sample stream — together representing 8% of all samples submitted for analysis. CRS Laboratory operates under ISO/IEC 17025 accreditation and is widely trusted by Nordic mining and exploration companies for geochemical analysis. All QAQC control samples returned results within acceptable limits for accuracy and precision, and no issues were identified that would affect the reliability of the assay dataset. All standards plotted within two standard deviations of certified values, all blanks returned below detection limit or below threshold and all duplicates showed <20% relative percent difference.
