Standard Uranium signs LOI for Rocas project

Mr. Jon Bey reports STANDARD URANIUM EXECUTES LETTER OF INTENT TO OPTION ROCAS URANIUM PROJECT IN EASTERN ATHABASCA BASIN Standard Uranium Ltd. has signed a letter of intent (LOI), dated Sept. 15, 2025, with Collective Metals Inc. (CSE: COMT), an arm's-length party. Pursuant to the LOI, the optionee will be granted the option to acquire a 75-per-cent interest in the 4,002-hectare Rocas project located in the eastern Athabasca basin region. Rocas project highlights Prime location: More than 7.5 kilometres of exploration strike length along a strong northeast-southwest magnetic low trend coincident with electromagnetic (EM) conductors and cross-cutting faults, providing shallow drill targets south of Key Lake. Uranium at surface: Mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.50 weight (wt.) per cent U3O8 and never drill-tested. New uranium targets: Results from a high-resolution ground gravity survey completed in 2024 highlight potential alteration halos and high-priority exploration targets along well defined structural corridors. The option is exercisable by the optionee completing cash payments and share issuances and incurring the exploration expenditures on the project; consideration payments consideration shares exploration expenditures operator.

The global demand for nuclear energy requires more uranium exploration and high-grade discoveries. There is no better place on the planet to make these discoveries than the Athabasca basin region. We look forward to completing this transaction and beginning phase one of our three-year exploration programs run by our Standard Uranium technical team." The project is located 75 kilometres southwest of the Key Lake mine and mill facilities along Highway 914. About the Rocas project The Rocas project comprises 4,002 hectares, located 75 kilometres southwest of the Key Lake mine and mill facilities along Highway 914 and approximately 72 kilometres south of the present-day margin of the Athabasca basin. The project was acquired via staking in May, 2023 and recently expanded by an additional 931 hectares. Standard Uranium holds a 100-per-cent interest in the property. The project covers 7.5 kilometres of a northeast trending magnetic low/electromagnetic (EM) conductor corridor which hosts several uranium showings, including historical mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.50 wt. per cent U3O81. Notably, none of the historical uranium occurrences have been drill-tested. Historical airborne EM work in 2017 defined conductive trends on the project west of and subparallel to the Key Lake Road shear zone, corresponding with favourable metasedimentary basement lithologies. Multiple parallel conductors, offsets and termination points indicate the trend widening and potential cross-cutting structures. Additionally, a 2007 field sampling program identified anomalous lakebed geochemical anomalies that statistically rank as greater than 95th percentile uranium, cobalt, vanadium and zinc along the conductor corridor, including high uranium/thorium (U/Th) ratios. Geophysical map of the Rocas project highlighting EM conductors, faults, historical uranium showings and anomalous lakebed geochemistry. 2024 ground gravity survey The company contracted MWH Geo-Surveys (Canada) Ltd. to complete a high-resolution ground gravity survey along known conductive exploration trends on the Rocas project. The surveys are designed to aid in the identification of potential zones of hydrothermal alteration of host rocks associated with uranium mineralization events. The gravity surveys across the conductive structural corridors improve definition of drill targets for future exploration programs. Convolutions Geoscience have completed detailed inversion and 3-D modelling, which will provide additional vectoring layers for future drill programs. Value-added products include 3-D density inversions, depth slices, modelling interpretation and expert recommendations. Four new drill target zones have been identified on the Rocas project, outlined via the confluence of low gravity anomalies, historical surface mineralization, lakebed geochemical anomalies, EM conductors and crosscutting fault zones. Three-year earn-in option Prior to exercise of the option, the company will act as the operator of the project and will be entitled to charge a 10-per-cent fee on expenditures in year one, increasing to 12 per cent in year two and year three. Following successful completion of the obligations of the option (that is, at the end of year three), optionee will acquire a 75-per-cent equity in the property, with Standard retaining 25 per cent as well as a 2.5-per-cent net smelter returns royalty on the project, of which 1.0 per cent may be purchased back at any time for a one-time cash payment of $1-million. The parties intend on forming an unincorporated joint venture for the further development of the project. The LOI is non-binding at this time and the grant of the option remains subject finalization and execution of definitive agreements. No finder's fee is payable by the company in connection with the option. (The company considers uranium mineralization with concentrations greater than 1.0 wt per cent U3O8 to be "high grade). (The company considers radioactivity readings greater than 300 counts per second (cps) to be "anomalous.") Qualified person statement The scientific and technical information contained in this news release has been reviewed, verified and approved by Sean Hillacre, PGeo, president and vice-president exploration of the company and a "qualified person" as defined in NI 43-101. Historical data disclosed in this news release relating to sampling results from previous operators are historical in nature. Neither the company nor a qualified person has yet verified this data and therefore investors should not place undue reliance on such data. The company's future exploration work may include verification of the data. The company considers historical results to be relevant as an exploration guide and to assess the mineralization as well as economic potential of exploration projects. About Standard Uranium Ltd.
