VanadiumCorp Reports Interim Metallurgical Results from Lac Dore Bulk Sample Testing

Core Viewpoint - VanadiumCorp Resource Inc. has reported positive interim results from its metallurgical testing program, indicating effective selective vanadium extraction and optimization of the processing flowsheet for its Lac Doré property [1][10]. Metallurgical Program Overview - The metallurgical testing program was executed in two phases to assess the beneficiation characteristics and evaluate downstream vanadium extraction options [3]. - Phase 1 focused on comminution and wet magnetic separation, resulting in a vanadium magnetite concentrate and an ilmenite pre-concentrate [4]. - The vanadium magnetite concentrate produced showed upgraded vanadium content suitable for further processing [5]. Phase 2 – Vanadium Extraction - Phase 2 involved oxidative roasting and sulfuric acid leaching to evaluate vanadium extractability from the beneficiated concentrate [6]. - Results indicated a positive correlation between roasting temperature and vanadium extraction efficiency, with recoveries reaching approximately 65% at 1,050°C [7][13]. Highlights of Interim Metallurgical Results - The vanadium-magnetite concentrate achieved a grade of approximately 0.93% V₂O₅ and ~78% Fe₂O₃, with a mass pull of ~63% under non-optimized conditions [13]. - Selective vanadium extraction was demonstrated, with limited dissolution of iron and titanium during leaching [13]. Strategic Significance - The interim results support the company's strategy to integrate hydrometallurgical processing with traditional beneficiation for a potential vanadium supply chain [10]. - The findings align with the company's proprietary VEPT hydrometallurgical process, which has shown high vanadium recoveries from similar feedstocks [10]. Recommendations for Further Work - IGS has recommended continued optimization, including refining the beneficiation flowsheet and conducting additional roasting and leaching tests [14].
