RDS Radisson Mining Resources Inc

Radisson Mining Resources Inc. (TSX-V: RDS, OTCQB: RMRDF) (“Radisson” or the “Company”) is pleased to announce the appointment of Mr. David Ross as Vice President of Exploration, effective immediately, and the acceleration of the Company’s ongoing, fully-funded 35,000 metre drill program at the Company’s O’Brien Gold Project (“O’Brien” or the “Project”) with the addition of a third drill rig.

Mr. Ross is a professional geologist with over 25 years of experience in mineral resource estimation and the exploration of structurally hosted gold deposits. He was until recently Vice President of Geology and Exploration at Calibre Mining Corporation and its predecessor company, Marathon Gold Corporation. At Marathon, David oversaw a significant growth in the mineral resource inventory at the Valentine Gold Project in Newfoundland and Labrador, and initiated Valentine’s ongoing programs of property-scale exploration and mining grade control. Prior to Marathon, David served as Senior Manager of Mineral Resources at Teranga Gold Corporation and served for fifteen years with Roscoe Postle Associates, now part of SLR Consulting Limited. David has a B.Sc. in Geology from Carleton University, an M.Sc. in Mineral Exploration from Queen’s University and is a Professional Geologist in the provinces of Ontario and Newfoundland and Labrador. He is an author and Qualified Person for over 50 NI 43-101 Technical Reports.

Matt Manson, President and CEO, commented: “I am very happy to be announcing the addition of Dave Ross to the Radisson team. Having worked with David previously, I know that his specific experience in exploring structurally hosted gold deposits, and his expertise and professionalism in mineral resource estimation, will give significant value to the Company as we continue to explore O’Brien and contemplate its future development. Dave’s leadership attributes will also benefit us as we look to develop our young Quebec based exploration team. Dave joins us as we are intersecting deep, high-grade mineralization at O’Brien, commencing a milling assessment with IAMGOLD focussed on the nearby Doyon mill, and completing a highly successful and oversubscribed financing for our 2025 work programs.”

Radisson further announces that the Company’s ongoing 35,000 metre drill program has been accelerated with the addition of a third drill rig, which will be in place until the end of the year. Recent deep drilling at O’Brien has confirmed significant high-grade mineralization at approximately 1,100 metres vertical depth, 170 metres below the current Mineral Resource and well below the level of the historic workings at the adjacent O’Brien Gold Mine. The Project remains open to the east, west and at depth. Additional results from the ongoing drill program are expected over the coming weeks and months.
