IsoEnergy Commences Athabasca Basin Winter 2025 Exploration Program
IsoEnergy (TSX: ISO; OTCQX: ISENF) has launched its 2025 winter exploration program in Canada's eastern Athabasca Basin with an approved budget of $5.3 million. The program includes 8,800 metres of drilling at the Larocque East project, home to the high-grade Hurricane deposit.
The exploration strategy has two main focuses: testing resource expansion near the Hurricane deposit (2,800 metres in seven holes) and evaluating greenfield targets along the Larocque Trend (6,000 metres in 15 holes). Previous drilling results showed promising intersections, including 1% U₃O₈ over 2.0m and 0.6% U₃O₈ over 4.5m.
Additionally, ground geophysical surveys are planned for the East Rim, Evergreen, and Hawk projects to advance these early-stage projects to drill-ready status. The company also provided an update on its previously announced arrangement with Anfield Energy, stating that while the outside date has passed, they are still considering options and alternatives.
IsoEnergy (TSX: ISO; OTCQX: ISENF) ha avviato il suo programma di esplorazione invernale 2025 nella parte orientale del bacino di Athabasca in Canada, con un budget approvato di 5,3 milioni di dollari. Il programma comprende 8.800 metri di perforazione nel progetto Larocque East, che ospita il deposito ad alta legge Hurricane.
La strategia di esplorazione ha due obiettivi principali: testare l'espansione delle risorse vicino al deposito Hurricane (2.800 metri in sette fori) e valutare i target greenfield lungo il Larocque Trend (6.000 metri in 15 fori). I risultati delle perforazioni precedenti hanno mostrato intersezioni promettenti, inclusi 1% U₃O₈ su 2,0 m e 0,6% U₃O₈ su 4,5 m.
Inoltre, sono previsti sondaggi geofisici a terra per i progetti East Rim, Evergreen e Hawk per far avanzare questi progetti nelle fasi iniziali verso uno stato pronto per la perforazione. L'azienda ha anche fornito un aggiornamento sul suo accordo precedentemente annunciato con Anfield Energy, affermando che, sebbene la data esterna sia passata, stanno ancora considerando opzioni e alternative.

- Comprehensive 8,800-meter drilling program with $5.3 million budget approved
- Previous drilling results showed high-grade uranium mineralization (1% U₃O₈ over 2.0m)
- Strategic expansion of exploration area along the prospective Larocque Trend
- Arrangement with Anfield Energy has passed its outside date without completion
Highlights
- Hurricane Deposit Resource Expansion
- Approximately 2,800 metres of drilling in seven holes will target gaps in historic drilling near the Hurricane deposit and 2024's Target Area B (Figure 2).
- Drilling will test areas where prior results indicate geochemical anomalies and alteration associated with fault extensions that control mineralization within the Hurricane resource (Figure 2).
- Greenfield Targets Along the Larocque Trend
- Up to 6,000 metres of drilling in 15 holes will test a six-kilometre segment of the Larocque Trend east of the Hurricane deposit (Figures 3 and 4).
- Drilling will focus initially on three target areas (D, E, and F) identified through 2024's integration of geophysical and geochemical data. The trend on which these target areas lie extends eastward on to IsoEnergy and Purepoint Uranium's joint venture announced late last year (Figure 2).
- Geophysical Surveys on Highly Ranked, Early-Stage Projects
- Ground geophysical surveys are planned on the East Rim, Evergreen, and Hawk projects (Figure 1) to advance targets to the drill-ready stage.
Dan Brisbin, Vice President of Exploration, stated, "We are eager to launch our winter exploration program, which includes testing deposit expansion targets around the margins of the Hurricane deposit and exploring for new deposits along the highly prospective Larocque Trend. Targets on this corridor were identified through a comprehensive integration of drill hole geology, geochemistry, alteration mineralogy, and geophysical data, including electromagnetic, DC resistivity, and ANT surveys. The approach builds on the understanding that
Resource Expansion Targets at Hurricane
Drilling will commence with testing resource expansion targets near the Hurricane deposit and between it and 2024 Target Area B (Figure 2). Review of 2024 and past drill results has highlighted gaps in drill hole patterns where nearby holes intersected indicative geochemistry and alteration along projected extensions of faults which control mineralization within the Hurricane resource.
Historical results on the south side of the Hurricane deposit are encouraging, with drill hole LE22-115A intersecting
Holes from the east end of the Hurricane resource footprint and to the east end of ambient noise tomography ("ANT") target Area B drilled in 2024 have strong illite clay alteration and uranium partial ("Up") geochemical signatures, and structural disruption so additional holes are planned to test drilling gaps in this area that is along the eastward strike extension of the faults that control the main portion of the Hurricane deposit.
Finally, review of historical drill hole data reveals that the northern faults at Hurricane – intersected in holes drilled from the north to intersect the deposit at depth (e.g. LE19-15) - remain largely untested at the unconformity, presenting a compelling target which will be tested this winter.
Regional Targets on the Larocque Trend
With addition of a second drill rig, drilling of greenfield targets are expected to proceed from west to east across the Larocque Trend, as drill trails are prepared. The Larocque Trend is an important regional structure that hosts the world-class Hurricane deposit and other notable high-grade occurrences including those on Cameco/Orano's Dawn Lake joint venture (Figure 3).
* See Qualified Person Statement below.
Three of the target areas (D, E, and F) defined in 2024 that will be prioritized are characterized by anomalous Up geochemistry, indicative clay species alteration mineralogy, and prospective structure projected from nearby holes within the Larocque Trend and within seismic low velocity zones defined by 2024 ANT surveys and resistivity lows outlined by past DC-resistivity surveys. A joint inversion of electromagnetic and DC resistivity data to develop improved resistivity mapping of alteration is in progress and will be used in refining drill targets. Planned drill holes will be focussed initially in areas D, E and F and plans will evolve depending on results as the program proceeds. Unconformity target depth shallows to the east and is at 175 m vertical depth in hole LE24-180 at Area E versus a 325 m at the Hurricane deposit.
Area D, corresponding to adjacent portions of areas D, I and J as defined by 2024 ANT surveys (see November 6, 2024, press release). The target area coincides with ANT low velocity and low DC-resistivity zones on the conductor corridor zone. Drill hole LE22-116 intersected 369 parts per million uranium partial ("ppm Up") in basal sandstone from 281.5 to 282.0 m and 2,750 ppm Up from 282.0 to 282.5 m in the basement (see July 15, 2022, press release). Similarly, drill hole LE24-177, completed during the summer of 2024, intersected up to 42.8 ppm Up in basal sandstone. This hole also encountered strong alteration features, including hydrothermal hematite and clay, along with significant sandstone structural characteristics.
Area E corresponds to an ANT velocity low roughly coincident with the hinge of an east-trending, moderately west-plunging fold at the east end of the property, where IsoEnergy's 2024 summer drilling following up on historic hole KER-17 intersected significant structures in all drill holes. Drill hole LE24-192 recorded up to 334 ppm Up over 0.5 m in sandstone and up to 1,110 ppm Up in the basement. Drill hole LE24-180 intersected up to 462 ppm Up in sandstone, while LE24-190 encountered strong clay alteration and structural features from 209 m to the unconformity at 268.6 m. Additionally, this hole recorded >1 ppm Up below 180 m in sandstone, with a maximum of 7.0 ppm Up from 265.1 to 265.6 m.
Area F, located in the northeast, is centered on the conductor corridor and aligns with roughly coincident ANT velocity low and resistivity anomalies. 2025 drilling in areas E and F will also help correlations between fertile trends on the Larocque East project and conductors on the
Developing Drill Targets on Additional Highly Ranked Projects
Ground gravity surveys are planned on the East Rim and Evergreen projects (Figure 1) that cover multiple conductive and structural corridors on the southeast basin margin. Stepwise moving loop electromagnetic surveys are planned for

The scientific and technical information contained in this news release was reviewed and approved by Dr. Dan Brisbin, P.Geo., IsoEnergy's Vice President, Exploration, who is a "Qualified Person" (as defined in NI 43-101 – Standards of Disclosure for Mineral Projects). All 'HK' and 'LE' series drill holes were completed by IsoEnergy, and geochemical analyses were completed for the Company by SRC Geoanalytical Laboratories ("SRC") in
For additional information regarding the Company's Larocque East Project, including the current mineral resource estimate for IsoEnergy's Hurricane Deposit [and the quality assurance and quality control ("QA/QC") procedures applied to the exploration work described in this news release, please see the Technical Report titled "Technical Report on the Larocque East Project,
Quality Assurance and Quality Control (QA/QC)
Quality Assurance in uranium exploration benefits from the use of down-hole gamma probes and hand- held scintillometers/spectrometers, as discrepancies between radioactivity levels and geochemistry can be readily identified.
IsoEnergy implemented its QA/QC program in 2019. CRMs are used to determine laboratory accuracy in the analysis of mineralized and unmineralized samples. Duplicate samples are used to determine analytical precision and repeatability. Blank samples are used to test for cross contamination during preparation and analysis stages. For each mineralized drill hole at least one certified reference material (CRM) blank, one CRM standard, and one duplicate sample (MDUP) is inserted in the MINZ sample series. One of two CRM standards is used: OREAS 124 (O124) if maximum grade is <
For unmineralized samples such as composite and spot samples, field insertions are made at the rate of
- Sample IDs ending in 00 will be certified blanks (BLA1).
- Sample IDs ending in 25 and 75 will be duplicates (DUPL) of the preceding sample.
- Sample IDs ending in 50 will be CRM OREAS 120 (O120).
In addition to IsoEnergy's QA/QC program, SRC conducted an independent QA/QC program, and its laboratory repeats (REPT), non-radioactive laboratory standards (LSTD), and radioactive lab standards (BL2A, BL4A, BL5) were monitored and tracked by IsoEnergy staff.
No QA/QC samples are inserted for reflectance samples as analyses are semi-quantitative only.
Assaying and Analytical Procedures
Composite and spot samples were shipped to SRC Geoanalytical Laboratories in
The samples were then dried, crushed, and pulverized as part of the ICPMS Exploration Package (codes ICPMS1 and ICPMS2) plus boron (code Boron). Samples were analyzed for uranium content, a variety of pathfinder elements, rare earth elements, and whole rock constituents with the ICPMS Exploration Package (plus boron). The Exploration Package consists of three analyses using a combination of inductively coupled plasma - mass spectrometry, inductively coupled plasma-optical emission spectrometry ("ICP- OES"), and partial or total acid digestion of one aliquot of representative sample pulp per analysis. Total digestion is performed via a combination of hydrofluoric, nitric, and perchloric acids while partial digestion is completed via nitric and hydrochloric acids. In-house quality control performed by SRC consists of multiple instrumental and analytic checks using an in-house standard ASR316. Instrumental check protocols consist of two calibration blanks and two calibration standards. Analytical protocols require one blank, two QA/QC standards, and one replicate sample analysis.
Samples with radioactivity over 350 CPS measured by Radiation Solutions RS- 125 were also shipped to SRC. Sample preparation procedures are the same as for the ICPMS Exploration Package, samples were analyzed by ICP-OES only (Code ICP1) and for U3O8 using hydrochloric and nitric acid digestion followed by ICP-OES finish, capable of detecting U3O8 weight percent as low as
Selective samples to be analyzed for gold, and in some instances, platinum and palladium, by fire assay using aqua regia digestion with ICP-OES finish. Analytical protocols utilized replicate sample analysis; however, no in-house standards were used for these small batches. Boron analysis has a lower detection limit of 2 ppm and is completed via ICP-OES after the aliquot is fused in a mixture of sodium superoxide (NaO2) and NaCO3. SRC in-house quality control for boron analysis consists of a blank, QC standards and one replicate with each batch of samples.
Borehole Radiometric Probing Method
All successfully completed 2024 drillholes were radiometrically logged using calibrated downhole Mount Sopris 2PGA-1000 probe which collects reading every 10 cm along the length of the drillhole. The 2PGA-probe was sourced from Alpha Nuclear and was calibrated for the summer 2024 program by IsoEnergy geologists at Saskatchewan Research Council facility in
Sample Collection Methods
All drill core was systematically logged to record its geological and geotechnical attributes by IsoEnergy geologists and geological technicians. All drill core is systematically photographed and scanned for radioactivity with a handheld Radiation Solutions RS-125 spectrometer. IsoEnergy geologists marked sample intervals and sample types to be collected based on geological features in the core and on radioactivity measured with the RS-125 in counts per second (CPS). Geologists and geological technicians complete the on-site collection of several types of samples from drill cores.
Composite geochemistry samples consist of roughly one-centimetre-long chips of core collected every 1.5 m to geochemically characterize unmineralized sections of sandstone and basement. Composite sample lengths are between five and ten m (typically 3 to 7 chips per sample). A minor revision to the sampling protocols introduced in 2024 is that rather than maintaining five metre sample lengths from 50 m above the unconformity to the unconformity, for five metres above and two metres below the unconformity composite sample intervals are now only 0.5 m long and the samples are composed of several chips of core in each interval. This is to provide better resolution of anomalous geochemistry along the unconformity, especially in greenfield exploration drill holes.
Split-core"spot" (i.e., representative) samples were collected through zones of significant but unmineralized alteration and/or structure. Spot sample length varies depending on the width of the feature of interest but are generally 0.5 m in length.
Split-core mineralization ("MINZ") samples are collected through zones of elevated radioactivity exceeding 350 CPS measured via RS-125 handheld spectrometer. MINZ samples are generally 0.5 m in length. One half of the core was collected for geochemical analysis while the remaining half is returned to the core box for storage on site. Intervals covered by MINZ samples are contiguous with and do not overlap intervals covered by composite samples.
Systematic short-wave infrared ("SWIR") reflectance ("REFL") samples were collected from approximately the middle of each composite sample for analysis of clays, micas, and a suite of other generally hydrous minerals which have exploration significance. Spot reflectance samples were collected where warranted (i.e., fracture coatings). Reflectance samples are not collected through mineralized zone.
For lithogeochemistry samples, sample tags with the sample number were placed in the sample bags before they are sealed and packed in plastic pails or steel drums for shipment to the Saskatchewan Research Council ("SRC") Geoanalytical Laboratories in
Geologists entered all geological, geotechnical and sample interval data into IsoEnergy's drill hole database during core logging.
Sample Shipment and Security
Drill core was delivered from the drill to IsoEnergy's core handling facilities at the Larocque Lake camp thereafter. Individual core samples were collected at the core facilities by manual splitting. They were tagged, bagged, and then packaged in five-gallon plastic buckets or steel IP-2 drums for shipment to SRC labs in
