00:00 Uhr  |  The Newswire

Vancouver - Uranium One Mining Corp. ("UraniumOne" or the "Company") (UUU: CSE |UUUFF: OTCID | SL51: Frankfurt) announces that, as a result of a review by the British Columbia Securities Commission ("BCSC"), the Company is issuing this news release to clarify its disclosure and has undertaken additional measures to ensure that its ongoing disclosure fully complies with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

In connection with the Company's news releases dated March 27, 2026, April 10, 2026, and April 21, 2026, the Company wishes to clarify and retract certain prior disclosure statements that were misleading or non-compliant with NI 43-101, and investors are cautioned that certain statements contained in those news releases should not be relied upon as compliant disclosure under NI 43-101.

The Company is committed to full compliance with applicable scientific and technical disclosure requirements and is implementing enhanced internal processes to ensure the accuracy and compliance of its future public disclosure.

Pocitos 1 Lithium Brine Project ("Pocitos 1")

Pursuant to the Company's news release dated April 21, 2026, UraniumOne announced that the technical report filed for Pocitos 1 was the "maiden" report for the project. The Company clarifies that it had previously filed a technical report for the project on December 21, 2023. The recently filed report was submitted in order to amend the prior report for compliance with NI 43-101.

In addition, the April 21, 2026, news release did not reconcile the changes to the report as required under Section 4.2(5)(b) of NI 43-101. Specifically, the project no longer contains a mineral resource estimate ("MRE") because the Company no longer holds the neighbouring Pocitos II property. The previously published MRE was based on both the Company's Pocitos 1 property (800 hectares) and the Pocitos II property (532 hectares). The Company notes that all drilling completed to date was conducted on the Pocitos 1 property.

Brussels Creek ("Brussels")

Pursuant to the Company's news release dated April 10, 2026, UraniumOne announced that the technical report filed for Brussels Creek was the "maiden" report for the project. The Company clarifies that it had previously filed a technical report for the project on April 22, 2021.

The April 10, 2026, news release also stated: "Filing our maiden NI 43-101 Technical Report… marks a significant milestone for Vanguard." The Company clarifies that the report was filed voluntarily and not pursuant to a requirement under Part 4 of NI 43-101, which outlines the project and issuer milestones that trigger mandatory technical report filings.

Redonda Copper-Molybdenum Project ("Redonda")

The Company's March 27, 2026, news release stated that "this milestone report validates the scale and geological potential" and that "this report represents a major milestone." The Company clarifies that the report was filed voluntarily and not pursuant to a requirement under Part 4 of NI 43-101.

The Company further clarifies that NI 43-101 technical reports do not "validate" or "confirm" the merits of an issuer's project or exploration results. While the Company remains encouraged by the ongoing results of its exploration program and the recommendations contained in the NI 43-101 report regarding proposed follow-up work programs, readers are cautioned not to interpret the filing of the technical report as independent validation of the project.

The March 27, 2026, news release also stated: "We now have independent confirmation of a large-scale copper-molybdenum system at Redonda, supported by both historical and modern drilling." The Company retracts this statement, as the Company had not independently verified the historical exploration results referenced in the disclosure.
