Vancouver, British Columbia--(Newsfile Corp. - May 22, 2024) - BASIN URANIUM CORP. (CSE: NCLR) (CNSX: NCLR.CN) ("Basin Uranium" or the "Company") is pleased to announce the filing of the NI 43-101 mineral resource estimate ("MRE") for its Chord uranium project located in Fall River County, South Dakota, USA. The Chord Uranium Project, Fall River County, South Dakota, USA Mineral Resource NI 43-101 Technical report was prepared by BRS Engineering Inc. with an effective date of May 7^th, 2024 (the "Technical Report"). A copy of the Technical Report can be found under the Company's issuer profile on SEDAR+ () and on the Company's website.

Chord MRE Highlights:

• Total inferred resources of 2.75 Mlb U₃O₈ at an average grade of 810 ppm over an average thickness of 8.5 feet.

• MRE was based off only 431 of the over 1,247 drill holes historically drilled at the Chord. The 431 drill holes had both reliable collar mapping and geophysical data available for interpretation.

• The areas underlying the MRE have the reasonable possibility of connectivity between them along trends within the same fluvial sands of the Inyan Kara group. These broad trends have been projected to connect the drilling in the Viking Area to the Ridge Runner, the Ridge Runner to the October-Jinx, and Southwest of October Jinx.

• The Company has delineated Exploration Targets at the Chord Project is estimated in the range of 1.42 to 4.23 Mlb U₃O₈ of potential as further described below. These targets currently have insufficient data and are conceptual in nature. Further exploration is needed to test them for mineralization. No guarantee is made that any future resource will be delineated by future exploration.

• Estimated Inferred Mineral resources for uranium are reported at a GT cutoff of 0.25 with a minimum intercept grade of 0.02% equivalent U3O8.

• A drilling program targeting the confirmation of the current resource would also provide data on the hydrogeology of the mineralized horizons and evaluate their potential for extraction by ISR methods. If the deposit or portions thereof are determined to be In-situ Recovery (ISR) amenable, similar grade and GT cut-offs as were applied to the current Inferred Resource would also be applicable.

• Data from two existing monitoring wells onsite indicates that the lower portion of the Chilson member lies within a saturated aquifer. The mineralized portion of this aquifer may prove to be potentially extractable by in-situ recovery (ISR) methods.

• The Fall River Uranium district is a past producer of approximately 250,000 tons of mineralized material. Mining in the project area was primarily limited to small sized open pit methods, and focused on the uppermost, oxidized mineral horizons within the Inyan Kara Group. The deeper mineral horizons, particularly with the October-Jinx area were left undeveloped but were strongly explored by Union Carbide Corporation in the late 1970's.

Total Inferred Mineral Resources

Pounds and tons as reported are rounded to the nearest 1,000.
Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Exploration Target Range Summary

Readers are encouraged to review the Technical Report and the Company's news release dated May 9, 2024 for additional information on the MRE and the exploration targets disclosed in this news release.

Chord Project, South Dakota

The Chord Project consists of 3,640 contiguous acres. The project lies on the southern end of the Black Hills, in Fall River County, South Dakota approximately seven miles north of Edgemont. Mineralization is sandstone-hosted, and channel-bound into tabular and lenticular deposits within the Lakota and Fall River formations of the Inyan Kara Group.

The Project lies within a historically explored and mined district. Nearly 300 historical uranium mines and prospects once dotted western South Dakota. Union Carbide Corporation (UCC) spent approximately $3.5 to 4.0 million dollars in development of the project in the late 1970's. UCC conducted extensive exploration drilling in the late 1970's, culminating in a Feasibility Study and planned conventional mine development by 1979.

The Chord Project is located just 5.5 miles southeast of enCore Energy's advanced stage and Nuclear Regulatory Commission (NRC) licensed Dewey-Burdock ISR uranium project, which is one of the Company's initial development priorities following the start of production in South Texas.

During the tabulation of the MRE the author and the Company were only able to accurately verify 35% of the holes historically drilled on the Chord property. This, in itself, provides the potential for significant exploration upside to increase the confidence and potential size of the resource at Chord. The Company will be working diligently to continue to upgrade the size and potential of the Chord project. In addition, Basin will also be undertaking steps to assess the ISR viability of the deeper sands that form the majority of the resource on the project. The Company has established exploration targets outside of the ground covered by the MRE, as disclosed below.

Investor Relations

Further to the Company's news release of April 18, 2024, the Company has increased the budget by EUR 100,000 with Plutus Invest & Consulting GmbH ("Plutus"). The consultant will provide strategic consulting services focused on market analysis and financial advisory and managing digital content to support the Company's business initiatives in Europe and beyond.

As of the date hereof, to the company's knowledge, Plutus (including its directors and officers) does not own any securities of the Company and has an arm's-length relationship with the Company. The Company will not issue any securities to Plutus as compensation for its marketing services.
