The Viken Deposit was previously subject to a historical Inferred Mineral Resource estimate of 3,019 Million Tonnes at an average grade 172 ppm U₃O₈ containing 1,145 Million Pounds U₃O₈, and a historical Indicated Mineral Resource estimate of 43 Million Tonnes at an average grade of 191 ppm U₃O₈ containing 18 Million Pounds U₃O₈.² In addition, a historical Inferred Mineral Resource estimate of 2,830 Million Tonnes at an average grade 2,680 ppm V₂O₅ containing 16,716 Million Pounds V₂O₅, and a historical Indicated Mineral Resource estimate of 23.6 Million Tonnes at an average grade of 3,130 ppm V₂O₅ containing 163 Million Pounds V₂O₅.³ A Qualified Person has not done sufficient work to classify the historical estimate as a current Mineral Resource, and the Company is not treating these historical estimates as current Mineral Resources.

Notes:

1. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

2. The Inferred Mineral Resource in this MRE has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

3. The Mineral Resource in this MRE was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

4. The MRE was based on consensus economics forecast US$ metal prices of $72/lb U₃O₈, $5/lb V₂O₅, $17/lb Mo, $8.50/lb Ni, $4.25/lb Cu and $1.30/lb Zn with respective process recoveries of 80%, 80%, 70%, 70%, 50% and 75%.

5. Overburden, waste and mineralized US$ mining costs per tonne mined were respectively $2.00, $2.50 and $3.00.

6. Processing and G&A US$ costs per tonne processed were respectively $20 and $2.

7. Constraining pit shell slopes were 45 degrees.

The MRE has been prepared in accordance with NI 43-101, has effective date of April 25, 2025, and takes into account the results from a total of 122 drill holes (by previous operators between 2006 and 2012) on the Viken Property, which consists of the Viken nr 1, Norr Viken, Lill Viken, Norra Leden, and Storviken mineral licenses that are 100% owned by the Company. The spacing of the drill holes ranges from 30 to 380 metres and averages approximately 300 metres. The mineralized Alum Shale extends under the entire Viken Property and beyond its boundaries.

The principal assay laboratory, ALS Minerals in Piteå, Sweden, used three different certified reference materials to monitor the accuracy of copper, nickel, uranium and zinc analytical results. Two of the standards were certified for copper, nickel and zinc, whereas the third one was certified for copper, nickel, uranium and zinc. For QA/QC purposes, every 25^th sample was sent to a second laboratory for re-analysis. Analyses were performed by ALS Chemex in Öjebyn and ALS Analytica in Luleå, Sweden. There were a total of 48 certified reference materials inserted by the lab for the drill programs.

A Technical Report prepared in accordance with NI 43-101 on the MRE will be filed within 45 days of this news release on District's issuer profile on SEDAR+ at www.sedarplus.ca. Additional supporting details regarding the information in this news release, will be provided in the MRE Technical Report, including all qualifications, assumptions and exclusions that relate to the MRE. The MRE Technical Report is intended to be read as a whole, and sections should not be read or relied upon out of context.

• The Company views the 2014 Viken Report as relevant and reliable.

• Block grades were estimated using Ordinary Kriging of capped composite samples. Only blocks wholly or partially within the mineralized shale domain were estimated, and between six and fifteen samples from two or more drill holes within 660 m of the block centroid were used for estimation. A small area in the Southern portion of the deposit with an average drillhole spacing of approximately 120 m has been classified as an indicated mineral resource.

• An internal break-even cut-off grade of US$11.00/tonne was used in reporting this historical estimate.

• The historical estimate categories are classified under the previous definition standards and do not match the current categories under NI 43-101.

• The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Viken deposit historical estimate as a current mineral resource.

• The mineral resource estimates is considered to be a "historical estimate" under NI 43-101 and a qualified person has not done sufficient work to classify the historical estimate as a current mineral resource and District is not treating the historical estimate as a current mineral resource.

• Weighting of composite samples by linear Ordinary Kriging was used for the estimation of block grades. Kriging parameters were based on the grade-element variography derived from the mineralized shale domain. A block discretization level of 5 x 5 x 2 was used during kriging. The mineralized shale domain was treated as a hard boundary, and data used during estimation were limited to composite samples located within the mineralized shale domain wireframe. Only blocks wholly or partially within the mineralized shale domain were estimated. The mineralized shale domain was treated as a hard boundary, and data used during estimation.

• During the first pass, four samples from each of three drill holes within 110m of the block centroid were required. All block grades estimated during the first pass were classified as Indicated.

• During the second pass, blocks not populated during the first pass were estimated. A minimum of three and a maximum of six samples from one or more drillholes within 330 m of the block centroid were required. All block grades estimated during the second pass were classified as Inferred.

• An internal break-even cut-off grade of US$7.50/tonne was used in reporting this historical estimate.
