Radisson Announces Results of its Annual and Special Meeting of Shareholders

Radisson Mining Resources Inc. (TSXV: RDS) (OTCQB: RMRDF) ("Radisson" or the "Company) is pleased to announce the results of its Annual and Special Meeting of Shareholders ("AGM") held on June 12, 2025. Shareholders voted in favour of all items of business, including the election of each director nominee, the appointment of auditors, and the adoption of a new Omnibus Equity Incentive Plan. A total of 156,469,851 votes were represented in the meeting amounting to 45.22% of the Company's class A shares issued as of the record date. Directors re-elected to the board were Pierre Beaudoin, Lise Chénard, Michael Gentile, Peter MacPhail, Matt Manson, Jeff Swinoga and Cindy Valence. Subsequent to the AGM, Pierre Beaudoin was re-appointed as Chairperson of the Board of Directors.

New Omnibus Equity Incentive Plan

The new Omnibus Equity Incentive Plan (the "Omnibus Plan") replaces the Company's previous stock option plan and introduces a best-practice framework to attract and retain personnel through a broader range of equity-based awards.

Under the Omnibus Plan, a rolling 10% share reserve will apply to all awards, including stock-options ("Options"), restricted share units ("RSUs"), performance share units ("PSUs"), and deferred share units ("DSUs"). The total number of common shares reserved for issuance under the Omnibus Plan, at any time, will not exceed 10% of the Company's issued and outstanding common shares. All outstanding stock-options granted under the previous plan will continue under the Omnibus Plan, unless the new plan materially impairs the rights of existing holders, in which case the terms of the original plan will remain in effect.

A full copy and summary of the Omnibus Plan is available in the Company's management information circular dated May 7, 2025, which can be accessed under Radisson's profile at www.sedarplus.ca and on the Company's website at www.radissonmining.com.
