[{"type":"text","content":"NioBay Improves the Concentrate Content by 56% as Compared to Historical Metallurgical Results\n\n\n\n MONTREAL, Oct. 20, 2025 (GLOBE NEWSWIRE) -- NioBay Metals Inc. (“\n \n NioBay”\n \n or the “\n \n Company”\n \n ) (\n \n TSX-V: NBY)\n \n (\n \n OTCQB: NBYCF\n \n ) is proud to announce the highlights of its metallurgical work carried out by SGS in Quebec City. This work was made possible thanks to a grant received under the Mining Exploration Support Program for\n \n Critical and Strategic Minerals\n \n of the Ministère des Ressources naturelles et des Forêts (“MRNF”) for its Crevier niobium & tantalum project (the “Crevier Project”). The Crevier Project is located approximately 50 km north of the town of Girardville and approximately 150 km from the Niobec mine and is located in the Nitassinan (or ancestral territory) of the Pekuakamiulnuatsh, whose main population center is Mashteuiatsh.\n \n\n\n Work completed\n \n\n\n The title of the funded project, “\n \n Demonstration of the niobium-tantalum concentration process on a pilot scale and production of niobium and tantalum oxides from the Crevier Project deposit located in the Lac St-Jean region,\n \n ” allowed the Company to test the robustness of the process flowsheet.\n \n\n Just under 10 mt of ore from the Crevier Project was used for the tests at a grade of 0.2% Nb\n \n 2\n \n O\n \n 5\n \n and 200 ppm Ta\n \n 2\n \n O\n \n 5\n \n .\n \n\n\n Results\n \n\n\n\n Niobay shipped several types of concentrates at the request of customers and partners. These concentrates had a niobium content of 16%, 17%, 32%, and 36% Nb\n \n 2\n \n O\n \n 5\n \n .\n \n\n Recovery reached a peak of 84.6% Nb\n \n 2\n \n O\n \n 5\n \n . The Company can establish an average recovery of 65% during the production of 17 kg of concentrate at 32% Nb\n \n 2\n \n O\n \n 5\n \n .\n \n\n With this pilot, Niobay was able to reproduce the previous results obtained in the laboratory in 2023 (Press Release dated January 25, 2023).\n \n\n Compared to the 2012 laboratory tests, the Company\n \n improved\n \n the final Nb\n \n 2\n \n O\n \n 5\n \n content of the concentrate\n \n by 56%\n \n , i.e., 20.3%** versus 36%.\n \n\n\n\n\n **THE DEVELOPMENT OF A SELECTIVE PROCESS FOR THE EXTRACTION AND RECOVERY OF TANTALUM AND NIOBIUM FRO...
