Standard Uranium Ltd. announced a summary of analytical results from the inaugural winter 2024 drill program at its 3,061-hectare Atlantic Project highlighting uranium mineralization in multiple drill holes. Atlantic is situated in the prolific eastern Athabasca Basin, northern Saskatchewan. Pursuant to the Option, the Optionee can earn a 75% interest in Atlantic over three years.

The Optionee-funded winter 2024 drill program contributes to completing the first year of minimum exploration expenditures required by the Option. Uranium Mineralization Confirmed: Analytical results from the winter 2024 drill program at the Project confirmed highly anomalous uranium in drill holes ATL-24-002, ATL-24-004A, and ATL-24-005A, coinciding with prospective structural zones and favorable alteration including dravite-rich clays. Sandstone & Basement-Hosted Uranium: Multiple zones of elevated uranium linked to the sub-Athabasca unconformity and basement structural zones were intersected, indicating a uranium-fertile system.

Verified Targets: Massive structural disruption confirmed in the sandstone column and multiple wide (>10 metres) brittle-reactivated graphitic shear zones confirm the main interpreted electromagnetic ("EM") corridor on the western claim block which was not reached by previous operators. The inaugural program results have confirmed the Company's exploration thesis on the Project, highlighting a uranium-fertile systems with several kilometres of still untested strike length across the Project. Follow Up Targets & Next Steps:Atlantic holds significant upside for discovery along the untested portions of the E-W conductor system.

The Atlantic project boasts all the key characteristics to host a high-grade unconformity-related uranium deposit, and the results of the inaugural drill program on the project have strengthened the validity of the exploration thesis on the Project. Core samples from the program have been submitted to Saskatchewan Research Council Geoanalytical Laboratory ("SRC") in Saskatoon, for geochemical assay and results will be reported once received and examined by the technical team in accordance with the Company's internal quality control processes. Winter 2024 Drill Program Analytical Highlights: The winter 2024 drill program comprised 3,316 metres of diamond drilling across 5 drill holes.

The highly prospective drilling results are visually summarized in schematic cross-sections highlighting dravite alteration, structure, and uranium results intersected during the inaugural drill program in Figures 3 and 4. The drill program was designed to follow up on highly anomalous uranium results returned from drill hole BL-16-32, in addition to testing the newly outlined gravity lows defined by the 2022 ground survey.

Drill hole intersections of uranium, dravite alteration, and structure are highlighted. Some of the material factors or assumptions used to develop forward-looking statements include, without limitation: that the transaction with the Optionee will proceed as planned; the future price of uranium; anticipated costs and the Company's ability to raise additional capital if and when necessary; volatility in the market price of the Company's securities; future sales of the Company's securities; the Company's ability to carry on exploration and development activities; the success of exploration, development and operations activities; the timing and results of drilling programs; the discovery of mineral resources on the Company's mineral properties; the costs of operating and exploration expenditures; the presence of laws and regulations that may impose restrictions on mining; employee relations; relationships with and claims by local communities and indigenous populations; availability of increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development (including the risks of obtaining necessary licenses, permits and approvals from government authorities); uncertainties related to title to mineral properties; assessments of mineral properties; assessments of mineral resources on the Company' mineral properties; and exploration expenditures; the presence the presence of laws and regulations That may impose restrictions on mining; employees with and claims by local communities, local communities and indigenous populations;availability of increasing costs associated with mining input and labour; the speculative nature.
