Monitoring Well Evaluation Continues to Demonstrate ISR Potential at Chord

Vancouver, December 13, 2023 - Basin Uranium Corp. (CSE: NCLR) ("Basin Uranium" or the "Company") is pleased to announce it has successfully confirmed the presence of a significant amount of water in multiple monitoring wells across the Chord Uranium Project (the "Property") in South Dakota. The confirmatory sampling of these wells continues to demonstrate potential for mineralization to be amenable to in-situ recovery (ISR) methods for at least the lower portions of the mineralization.

"The well sampling and water level measurements were completed by the Company. Parallel to this work, mineral resource modelling is underway by our consultants, BRS," commented Mike Blady, CEO of Basin Uranium. "Mineral resource estimation will consider reasonable prospects for economic extraction. The recent confirmation of the hydrologic setting of the mineralization will aid in this evaluation. In-situ mining is the most prevalent form of uranium production in the USA due to its minimal environmental impact, small footprint, and low development and operating costs."

Monitoring Well Sampling and Evaluation Program

The Company sampled two existing monitoring wells across the Chord project, both of which confirmed the presence of a significant amount of water. Monitoring well B-5, which is located on the southwestern and down dip edge of the October-Jinx mineralized body, was measured to a depth of 496 feet and was terminated in the Lakota Formation which is the same formation that is host to the uranium mineralization on the Property. The bottom 100 feet of the well contained ground water which was sampled with analytical results demonstrating the presence of anomalous concentrations of uranium, dissolved solids, sulfate and radionuclides (gross alpha, gross beta and radium-226). The combination of a significant hydraulic head from the bottom 5 feet of the well in addition to the presence of anomalous concentrations of uranium and radionuclides continue to support the viability of the mineralization to be amenable to in-situ recovery methods. Monitoring well B-4 was located within the Viking mineralized body, approximately two miles to the northwest, was drilled to 315 feet with a 5 five screened interval, contained 40 feet of groundwater.

Overall, results from the hydrology and water sampling of wells B-4 and B-5 were in line with historic test work completed by Union Carbide in the late 1970's and subsequent consultants in the 1980's (Cohan, 1984). The Company cautions that additional tests are required to validate these results in addition to the drilling of new monitoring wells to properly characterize the aquifer and define the parameters for in-situ recovery.

In general, to support the use of ISR methods, hydrogeologic data is required to demonstrate the following:

1) Permeability of the mineralized horizon;
2) Hydrologic confinement of the mineralized horizon; and
3) Ability to return groundwater within the mined area to its original baseline quality and usage.

The reader is cautioned that at this time it is too early to assess the feasibility of these recovery methods at Chord however, mineralization at this depth typically lies within the parameters of ISR mining and recovery.
