Standard Uranium drills Davidson River Project; Saskatchewan
Standard Uranium Ltd. [TSXV: STND; OTCQB: STTDF; FSE: 9SU0] reported that drilling activities have been completed at its flagship Davidson River Uranium Project located in the southwest Athabasca Basin, Saskatchewan, Canada.
Drilling began on June 1, 2026, and a total of 6,734 metres have been completed across the Warrior, Bronco, and Thunderbird structural corridors. The summer drill campaign was designed to target basement-hosted, high-grade uranium mineralization on the same regional structural trends that host significant uranium deposits including NexGen Energy’s Arrow deposit and Paladin Energy’s Triple R deposit.
“This program has returned the highest radioactivity recorded to date on the Project and more than doubled the known width of the Thunderbird and Bronco structural corridors. We have intersected our most prospective rocks yet, with strong hydrothermal alteration including sericite and dravitic clays, linked to widespread structural disturbance – the perfect geological environment for basement-hosted uranium mineralization,” said Sean Hillacre, P.Geo., President & VP Exploration of Standard Uranium.
“Completing our largest drill program ever and seeing prospective results from our integrated targeting thesis on Davidson River is a significant milestone for the Company. The striking similarities we see between these rocks and the structural settings of known deposits in the area give us increased confidence in where we will focus our next phase of exploration.”
Highlights: A total of 6,734 metres were completed across twelve diamond drill holes across target areas along the Warrior, Bronco, and Thunderbird conductor corridors.
Multiple intervals of anomalous radioactivity >300 counts per second (CPS) were intersected in three drill holes, totalling 5.0 metres of composite radioactivity across all intervals. All structural corridors remain open along strike.
Anomalous radioactivity is hosted within paragneiss, pegmatite, and granitoid orthogneiss units. Structural settings include hydrothermally altered graphitic fault zones and quartz-carbonate veining – all consistent with known uranium mineralization in the region.
Initial results from samples containing clay alteration analyzed by Short Wavelength Infrared Reflectance (SWIR) via a Portable Infrared Mineral Analyzer (PIMA) to verify clay species have confirmed dravitic-clay alteration in drill hole DR-26-040 along the Bronco corridor.
Whole-rock geochemical assays of drill core samples are pending. Several priority uranium targets remain along >60 km of untested strike length, and additional exploration programs are being planned to follow up on radioactive intervals and continue developing and testing regional drill targets across the project.
The summer drill program comprised 6,734 metres across twelve drill holes, three of which intersected anomalous radioactivity within multiple intervals. One drill hole was restarted due to difficult ground conditions.
The summer program began testing high-priority target areas defined by data integration and modeling of the Project’s existing datasets and a Multiphysics survey, comprising combined real-time 3D Ambient Noise Tomography (ANT), Horizontal-to-Vertical Spectral Ratio (HVSR), and ground gravity surveys completed on select areas of the Warrior, Bronco, and Thunderbird conductor trends. Initial radiometric results.
Targets were selected and prioritized through an iterative approach working in collaboration with Fleet Space and Convolutions Geoscience Corp., targeting compelling geophysical signatures and favorable geological/structural settings.
The 12 completed drill holes encountered highly favorable geological settings for basement-hosted uranium deposits, including five metres of anomalous radioactivity (>300 cps) intersected across multiple intervals in three drill holes.
Significant graphitic faults and shear zones were intersected in multiple drill holes, more than doubling the known width of the Thunderbird and Bronco structural corridors to greater than 300 metres across strike. The modeled structural geometry at Davidson River from new drill results matches the stacked shear zone geometry of the neighbouring Patterson Lake Corridor.
Drilling intersected prominent brittle reactivation features including breccias, cataclasites, fault gouge, strong fracturing and local shearing all of which are consistent with environments hosting uranium mineralization in the region.
Multiple intervals of moderate to strong hydrothermal alteration including sericite and dravitic clays, hematite, and quartz-carbonate veining.
Drill core samples have been collected systematically throughout all drill holes for whole-rock multi-element geochemical analysis and samples from zones of anomalous radioactivity have been submitted to SRC Geoanalytical Laboratories in Saskatoon for U3O8 assay. These analytical results will be integrated with the detailed logging information and geophysical datasets to prioritize follow-up target areas for future drill testing, in addition to testing of numerous other priority regional targets.
Davidson River includes 10 contiguous mineral dispositions totaling 30,737 hectares and lies approximately 25 km west of the Arrow and Triple R uranium deposits and 75 km south of the past-producing Cluff Lake uranium mine.
The company has now completed 23,295 metres of diamond drilling in 51 drill holes on the Davidson River property since 2020, which has further refined the exploration strategy for high-grade basement hosted uranium mineralization on the property. The flagship property hosts more than 70 km of conductive trends across four main structural corridors – the Warrior, Bronco, Thunderbird, and Saint trends. All four geophysical corridors contain multiple target areas favorable for high-grade basement hosted uranium mineralization.
Geochemical assays are pending. Samples collected for analysis were sent to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan for preparation, processing, and ICP-MS or ICP-OES multi-element analysis using total and partial digestion and boron by fusion.
Samples containing clay alteration were sent to Rekasa Rocks Inc. in Saskatoon, Saskatchewan to be analyzed by Short Wavelength Infrared Reflectance (SWIR) via a Portable Infrared Mineral Analyzer (PIMA) to verify clay species.
Historical data disclosed in this news release relating to sampling results from previous operators are historical in nature.
Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world’s richest uranium district. The company holds interest in over 272,035 acres (110,089 hectares) in the world-class Athabasca Basin in Saskatchewan.
Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.
Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin comprises 10 mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries.
However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.
Standard Uranium’s eastern Athabasca projects comprise over 59,748 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.
Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.
