[{"type":"text","content":"Radisson Announces Positive Metallurgical Study at O'Brien and Provides Update on Milling Assessment at IAMGOLD's Doyon-Westwood ComplexRouyn-Noranda, Quebec--(Newsfile Corp. - February 3, 2025) - Radisson Mining Resources Inc. (TSXV: RDS) (OTCQB: RMRDF) (\"Radisson\" or the \"Corporation\") is pleased to provide the results of a recent metallurgical study at the Company's 100%-owned O'Brien Gold Project (\"O'Brien\" or the \"Project\") located in the Abitibi region of Québec. The study was undertaken in conjunction with a milling assessment under the auspices of a Memorandum of Understanding (\"MOU\") with IAMGOLD Corporation (\"IAMGOLD\") to assess the design criteria for processing mined material from Radisson's O'Brien Gold Project (\"O'Brien\" or the \"Project\") at the nearby Doyon gold mill, part of IAMGOLD's Doyon-Westwood mine complex. The Doyon mill is located 21 kilometres west of O'Brien and directly accessible along Trans-Canada Highway 117. Gold recoveries of between 86% and 96% were obtained based on a series of flow sheet options, all of which are compatible with the Doyon mill with minimal or modest additional capital. The metallurgical program was undertaken at the Lakefield, Ontario facilities of SGS Canada Inc. (\"SGS-Lakefield\") under the supervision of Ausenco Engineering Canada ULC. (\"Ausenco\"). Highlights are as follows:Gold recovery of 86% based on a simple flow sheet of Gravity-Leach;Gold recovery of 90% based on a Gravity-Flotation-Regrind-Leach flow sheet;Gold recoveries of between 94% and 96% based on the sale of a flotation concentrate in a Gravity-Flotation-Concentrate Sale flow sheet after consideration for payability factors of 90% to 95% respectively; andAverage arsenic values of 0.4% to 0.5% in whole rock and 4.6% in flotation concentrate, consistent with precedent projects in Québec's Abitibi and offtake threshold limits for concentrates of high-grade gold projects.Matt Manson, President and CEO, commented: \"We are very happy with the results of this metallurgical study at O'Brien, undertaken within the context of our milling assessment MOU with IAMGOLD. This is the first metallurgical program at O'Brien based on a comprehensive suite of representative samples and with a specific mill in mind. We see multiple flow sheet options for O'Brien, each of which gives gold recoveries abo...
