Insights

Significant high-grade uranium discovery at Dorado Project with excellent 8.1% U3O8 results indicating strong economic potential.

The assay results from the Dorado Project represent a significant uranium discovery with impressive grades. The highlight intersection of 8.1% U3O8 over 0.4 meters within a broader 2.1-meter zone grading 1.6% U3O8 is particularly noteworthy in the uranium sector. These are exceptional grades when you consider that many economic uranium deposits operate at grades below 1%.

The Nova discovery zone is showing multiple mineralized intervals in the same drill hole (PG25-07A), with an additional 4.9 meters at 0.52% U3O8 including higher-grade sections. This pattern of stacked mineralization suggests a robust hydrothermal system capable of concentrating uranium in multiple horizons.

From a geological perspective, this discovery appears to be in the basement rocks below the Athabasca Basin's unconformity (given the depths of 380+ meters), which is consistent with other significant uranium deposits in the region. While the release doesn't specify the deposit style, the high grades and structural controls suggested in the release are typical of unconformity-related uranium deposits that the Athabasca Basin is famous for.

The interrupted drilling program due to wildfires is unfortunate but not uncommon in northern Saskatchewan. Despite completing only 5,030 meters of the planned 5,400 meters, the program has achieved its primary objective of confirming high-grade mineralization. The deferral of the Celeste project drilling is a minor setback but reasonable given the safety concerns.

The joint venture structure (50/50) between IsoEnergy and Purepoint provides balanced exposure to this discovery for both companies, with shared costs and risks. For Purepoint, as the smaller partner, this discovery could be particularly transformative to their overall asset portfolio and market valuation.

High-grade uranium discovery provides Purepoint with significant upside potential amid improving uranium market fundamentals.

These initial assay results demonstrate exceptional uranium grades that significantly enhance the economic potential of the Dorado Project. The 8.1% U3O8 over 0.4 meters is particularly impressive when compared to the global average uranium grade of approximately 0.1-0.2% for operating mines. Even the broader intervals of 1.6% over 2.1 meters and 0.52% over 4.9 meters represent grades well above what would typically be considered economic.

From an investment perspective, the timing of this discovery is especially favorable. The uranium market has been strengthening with prices rising from the $20s/lb earlier this decade to around $60-70/lb currently, driven by supply constraints and growing nuclear power demand for clean energy. High-grade discoveries like Nova become substantially more valuable in this pricing environment.

For Purepoint specifically, as the smaller market cap partner in this 50/50 joint venture, this discovery could be transformative. Junior explorers with significant high-grade uranium discoveries in the Athabasca Basin have historically seen substantial market revaluations. The partnership with IsoEnergy, which has a stronger balance sheet, also ensures the project can be advanced without immediate capital constraints.

The multiple mineralized zones identified in PG25-07A suggest potential for a sizeable resource with continued drilling. While the wildfire interruption is unfortunate, the company has still managed to establish a solid foundation for follow-up work. The assay results provide hard evidence of the system's potential, reducing investor risk for the next phase of exploration.

Investors should note that the Nova discovery appears to be open in multiple directions based on the longitudinal section and planned follow-up drilling mentioned. This suggests significant resource growth potential in 2026 drilling programs, creating a compelling catalyst timeline for both companies.

Toronto, Ontario--(Newsfile Corp. - September 18, 2025) - IsoEnergy Ltd. (NYSE American: ISOU) (TSX: ISO) ("IsoEnergy") and Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) ("Purepoint") today announced the receipt of partial assay results from the summer drill program at the companies' 50/50 joint venture Dorado Project (the "Dorado Project"), located on the southeastern margin of Saskatchewan's Athabasca Basin. The highlight comes from drill hole PG25-07A, which returned 2.1 metres grading 1.6% U₃O₈, including 0.4 metres at 8.1% U₃O₈ and an additional 4.9 metres at 0.52% U₃O₈ representing the most significant assay intervals reported to date from the Nova discovery zone (see Table 1 below).

"Eight percent uranium is an excellent grade from the centre of the very strong radioactive interval drilled by hole 7A," said Chris Frostad, President and CEO of Purepoint Uranium. "These assays reinforce the strength of this newly discovered system and provide a solid anchor point as we continue to test the mineralized structure in all directions."

Highlights:

  • Drill hole PG25-07A intersected 0.4 metres at 8.1% U₃O₈ from within 2.1 metres of 1.6% U₃O₈ at the Nova discovery zone. The hole also returned an additional 4.9 metres at 0.52% U₃O₈, that included 0.4 metres at 2.9% U₃O₈.

  • Select samples from PG25-07A were fast-tracked for assay to confirm uranium grades and mineral composition. Full assays from all holes remain pending.

  • A total of 5,030 metres were completed across 11 holes before wildfires curtailed the planned 5,400-metre summer drill program.

  • Additional drilling at Serin and Turaco targets, within the Dorado Project, has provided valuable data for calibration of the project's geophysics.

  • Celeste project drill program deferred due to ongoing wildfire risks across northern Saskatchewan.

  • Follow-up programs planned for early 2026 pending final assays and geologic/geophysical interpretation.

Despite having time and budget remaining, the program was cut short due to regional wildfires that limited helicopter access and created hazardous field conditions. As a result, drilling at the nearby Celeste project, also a Purepoint-IsoEnergy joint venture, has been deferred to a future program.

Turaco Grid Drilling

Two holes (TUR25-01 and TUR25-02) totaling 832 metres were completed at the Turaco Grid, targeting two parallel, newly reinterpreted airborne electromagnetic (EM) conductors within Zone 3. Neither hole encountered anomalous radioactivity, but both the results will help calibrate the Dorado Project's updated geophysical model. The highest radioactivity returned from the downhole probe was 578 CPS.

Serin Grid Drilling

Two holes (SL25-10 and SL25-11) were drilled at the Serin Grid, totaling 1,032 metres. While uranium mineralization was not encountered in SL25-10, anomalous radioactivity was hosted by a 6-metre-wide chloritized pegmatite in SL25-11 and returned up to 1,200 CPS from the downhole gamma probe. The drill hole results provide valuable insights into the basement geology and structural context that will guide future targeting.

Next Steps

Purepoint and IsoEnergy are now awaiting the full suite of geochemical assays and structural interpretations for the 2025 drill program. The results will support detailed planning for follow-up drilling in 2026, focused on expanding Nova and testing priority corridors across the broader Dorado Project property.

About the Dorado JV Project

The Dorado Project (Figure 3) is the flagship project of the IsoEnergy-Purepoint 50/50 joint venture, a partnership encompassing more than 98,000 hectares of prime uranium exploration ground. The Dorado Project includes the former Turnor Lake, Geiger, Edge, and Full Moon properties, all underlain by graphite-bearing lithologies and fault structures favorable for uranium deposition.

Recent drilling by IsoEnergy east of the Hurricane Deposit has intersected strongly elevated radioactivity in multiple holes. The anomalous radioactivity confirms the continuity of fertile graphitic rock package and further highlights the opportunity for additional high-grade discoveries across the region.

The shallow unconformity depths across the Dorado Project property—typically between 30 and 300 metres—allow for highly efficient drilling and rapid follow-up on results.

Gamma Logging and Geochemical Assaying

A Mount Sopris 2PGA-1000 downhole total gamma probe was utilized for radiometric surveying. All drill intercepts are core width and true thickness is yet to be determined.

Core samples are submitted to the Saskatchewan Research Council ("SRC") Geoanalytical Laboratories in Saskatoon. The SRC facility is independent of IsoEnergy and Purepoint and is ISO/IEC 17025:2005 accredited by the Standards Council of Canada (scope of accreditation #537). The samples are analyzed for a multi-element suite, including uranium, using partial and total digestion and inductively coupled plasma (ICP) mass spectroscopy (MS) and optical emission spectroscopy (OES) methods. Boron sample analysis includes by fusion in a Na2O2/NaCO3 flux. followed by solution in deionized water and analysis by ICP-OES. The U3O8% values reported here are derived from uranium-total (Ut) results measured by total digestion preparation followed by ICP-OES analysis. The Ut results are reported by SRC in parts per million (ppm) and are converted to U3O8% by multiplying by 1.17924 and dividing by 10,000.

The basement rock drill core is NQ in size and samples are created in the field by spitting the core in half. Field duplicate samples are also created in the field by spitting every 30th sample of remaining core; one quarter is sent to the laboratory and one quarter of the core remains in the core box. Data verification includes internal SRC laboratory quality assurance and quality control (QA/QC), blanks, comparison of results of the duplicate samples and variance of standard samples.
