Vancouver, British Columbia--(Newsfile Corp. - September 5, 2024) - Standard Uranium Ltd. (TSXV: STND) (OTCQB: STTDF) (FSE: 9SU) ("Standard Uranium" or the "Company") is pleased to announce that drilling activities have been completed at the Company's Sun Dog Uranium Project ("Sun Dog", or the "Project") located near Uranium City in northwestern Saskatchewan (Figure 1). The program was designed to test the newly identified Wishbone target area for high-grade basement hosted uranium deposits, typical of the Athabasca Basin.
The Project is currently under a three-year earn-in option agreement (the "Option") with Aero Energy Ltd. (TSXV: AERO) ("Aero") that was executed on October 20, 2023. The program was funded by Aero and operated by Standard Uranium. Sun Dog covers an area of 48,443 acres (19,604 Ha) across nine mining claims and is located 15 km Southeast of Uranium City on the northern margin of the Athabasca Basin. It hosts the historical Gunnar Uranium Mine, discovered in 1952, which doubled Canada's uranium production and became the largest uranium producer globally in 1956. The Gunnar Mine produced approximately 18M lbs of U3O8 between 1953 and 19811,2.
Highlights:
Anomalous Radioactivity at Wishbone: A total of 1,593 metres were completed across eight drill holes targeting shallow high-grade* basement-hosted uranium mineralization at the Wishbone target area (Figure 2). Intervals of anomalous radioactivity** >300 counts per second ("cps") were intersected in seven of eight drill holes.
Significant Structure & Alteration: Strongly graphitic fault rocks exhibiting evidence of brittle reactivation were intersected on both fold limbs of the Wishbone target area, coincident with widespread clay-sericite alteration and hydrothermal hematite. These rocks and alteration products signal an ideal environment for basement hosted uranium deposits.
Prospectivity Model Confirmed: Elevated radioactivity and increased hydrothermal alteration at Wishbone are largely associated with stacked graphitic structural zones, indicating favorable corridors for fluid movement and uranium deposition akin to other basement-hosted Athabasca deposits.
Assays Pending & Follow-Up Drilling Planned: Following uranium assay and geochemical analysis of drill core samples, additional geophysics and a second phase drilling program are being planned to follow-up along strike of mineralized drill holes and continue testing of priority regional drill targets across the Project.
"The team and I are very encouraged by the results of the first pass drilling at the Wishbone target. The results provide proof of concept for our exploration model, and we look forward to following up in this area with additional geophysical surveys and drilling to vector into a new high-grade discovery," said Sean Hillacre, President & VP Exploration of Standard Uranium. "In addition, the McNie target area north along strike from Wishbone, and Spring Dome to the south, provide several more kilometers of prospective corridor strike length coincident with surface uranium showings that remain untested by modern exploration methods."

The summer drill program comprised eight drill holes totalling 1,593 metres at the high-priority Wishbone target area following completion of a VTEM Plus survey and geophysical modeling earlier this year. A summary of radiometric*** results is provided in Table 1 and drill hole information is provided in Table 2. Select drill core photos are provided in Figure 3 and Figure 4.
Wishbone Target Area:
Approximately five kilometres of strike length along a regional scale anticline, defined by strong VTEM conductors with associated radioactivity along each fold limb.
Graphitic pelites have been mapped along both fold limbs, hosting strong radioactivity up to 22,300 cps (RS-125 Scintillometer).
Mineralized cross-cutting faults have been mapped in the overlying rocks which intersect the uranium-bearing graphitic pelite unit.
Historical outcrop sampling at the northwestern graphitic pelite exposure returned assay results of 0.32% U3O8 and 0.30% Cu (SMDI #2095).
Targets were selected and prioritized through an iterative approach working in collaboration with Aero and Convolutions Geoscience Corporation, targeting compelling geophysical signatures and favorable geological/structural settings. Recent prospecting and mapping at the Wishbone target area outlined multiple outcrops of favourable uranium host-rocks, including graphitic pelite, which is commonly radioactive over >200 m of collective strike length.
The eight completed drill holes encountered highly favorable geological settings for high-grade basement-hosted deposits associated with the Athabasca Basin, including:
Intervals of anomalous radioactivity (>300 cps) intersected in seven of the eight drill holes completed, associated with structural zones and favorable rock types including graphitic pelite.
Graphitic-sulphidic stacked shear zones were encountered in multiple holes, many featuring prominent brittle reactivation features including breccias, cataclasites, and fault gouge.
Significant hydrothermal alteration was intersected within all holes, including widespread hematization redox front alteration halos, sericitization, and structure-hosted chloritization. Strongly graphitic fault rocks are present all eight drill holes. Holes that intersected deformed pelitic gneiss were to host multiple metres of moderate to intense graphite mineralization.
Regional structural setting confirmed, comprising an anticline with faulted hangingwall rocks overlying multiple graphitic horizons, effectively doubling prospective strike length due to folding (i.e., both limbs are prospective at Wishbone).

Other high-priority target areas including McNie, Haven, Java, Skye, and Spring Dome are being reviewed with new datasets and models for a possible winter drill program in 2025.
Next Steps
Drill core samples have been collected systematically throughout all drill holes and half-core of the zones of radioactivity higher than 300 cps and will be submitted to SRC Geoanalytical Laboratories in Saskatoon for U3O8 assay and multi-element characterization. These analytical results will be integrated with the detailed logging information to prioritize follow-up target areas for future drill testing, in addition to testing of numerous other priority regional targets.

About Standard Uranium (TSXV: STND)
We find the fuel to power a clean energy future
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 209,867 acres (84,930 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada. 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 has successfully completed three joint venture earn in partnerships on their Sun Dog, Canary, and Atlantic projects totaling over $23.8M in work commitments over the next three years from 2024-2027.
Standard Uranium's Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten 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 eight eastern Athabasca projects comprise thirty mineral claims over 32,838 hectares. 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, Saskatchewan, 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.
