VanadiumCorp Reports Interim Results on Vanadium Extraction
Vancouver, British Columbia — February 11, 2026 — Leads & Copy —
VanadiumCorp Resource Inc. (TSX‑V: VRB) (FSE: NWNA) (OTC: VRBFF) reports interim results demonstrating selective vanadium extraction, supporting continued optimization of the flowsheet. Impact Global Solutions Inc. (IGS) conducted the metallurgical testing program on bulk samples from the flagship Lac Doré vanadiferous titanomagnetite property near Chibougamau, Québec.
The testing program, detailed in the Company’s news release dated March 27, 2024, evaluated beneficiation and downstream vanadium extraction options for Lac Doré mineralization to advance the Company’s strategy of developing a secure, low-carbon vanadium supply chain.
The IGS metallurgical test program was designed and executed in two sequential phases to assess the beneficiation characteristics of the Lac Doré material and to evaluate the amenability of the resulting vanadium-bearing concentrate to downstream thermal and hydrometallurgical extraction.
Phase 1 test work focused on comminution, followed by wet magnetic separation to evaluate the recovery and upgrading of vanadium-bearing magnetite and associated ilmenite. The Lac Doré material demonstrated a consistent response to conventional grinding and magnetic separation techniques, resulting in the production of a vanadium magnetite concentrate and an ilmenite pre-concentrate.
The vanadium magnetite concentrate produced exhibited upgraded vanadium content and mineralogical characteristics considered suitable for subsequent thermal treatment and hydrometallurgical processing. The results indicate that no atypical or non-standard beneficiation techniques are required at this stage of process development.
Phase 2 scoping‑level test work evaluated the extractability of vanadium from the beneficiated vanadium magnetite concentrate using oxidative roasting followed by sulfuric acid leaching. Roasting tests were conducted across a temperature range of approximately 800°C to 1,050°C to assess the influence of thermal treatment on vanadium liberation and subsequent leach recovery.
Results demonstrated a positive correlation between roasting temperature and vanadium extraction efficiency during leaching. Increasing roasting temperatures led to progressively higher vanadium recoveries, indicating enhanced conversion of vanadium to acid‑soluble phases. Iron and titanium remained largely insoluble under the tested roasting and leaching conditions and reported predominantly to the solid leach residue.
These outcomes indicate selective vanadium extraction under the evaluated roast-leach conditions, with limited dissolution of iron and titanium, supporting further assessment of downstream vanadium recovery processes.
Preliminary tests achieved a vanadium‑magnetite concentrate grading approximately 0.93% V₂O₅ and ~78% Fe₂O₃, with a mass pull of ~63% in non‑optimized conditions.
Selective vanadium extraction from the magnetite concentrate demonstrated increasing recoveries with higher roasting temperatures, reaching up to ~65% vanadium recovery at 1050°C.
Iron and titanium were largely unaffected during vanadium leaching, supporting selective vanadium recovery.
Kristien Davenport, CEO of VanadiumCorp, stated the initial metallurgical results show Lac Doré mineralization can be processed into vanadium-bearing magnetite concentrate, with vanadium selectively extracted under current conditions. These findings represent an important technical step toward further evaluating processing methods for a potential integrated vanadium supply chain for long-duration energy storage.
Based on the results of the interim test work, IGS has recommended continued optimization work, including refinement of the beneficiation flowsheet and additional roasting and leaching tests to improve vanadium recovery.
The metallurgical test work reported herein is preliminary in nature and was conducted under non-optimized laboratory conditions. The results are intended to assess technical amenability only and do not constitute an economic or production decision.
VanadiumCorp Resource Inc. is a Canadian resource company focused on developing vanadium-based materials for the energy storage and steel markets.
The Company’s core assets include the Lac Doré Vanadium-Iron-Titanium Project near Chibougamau, Québec, one of the largest undeveloped vanadium resources in North America, and the Iron-T Project.
VanadiumCorp is advancing an integrated strategy spanning resource development, processing flowsheet optimization, and downstream electrolyte production, targeting the growing demand for long-duration energy storage solutions required to support grid stability and renewable energy integration.
“Results indicate the technical potential of producing a vanadium-rich feedstock suitable for preliminary evaluation in downstream electrolyte processing studies.
These interim results support VanadiumCorp’s strategy of evaluating the integration of hydrometallurgical processing with traditional beneficiation as part of a potential future vanadium supply chain for vanadium flow battery (VFB) electrolytes from a domestic Québec resource.
The production of high-grade vanadium-bearing magnetite concentrates from representative Lac Doré VTM mineralization under the reported test conditions supports further optimization of the Company’s patented and proprietary processing flowsheet.
The Company plans to advance additional hydrometallurgical test work to evaluate vanadium recovery pathways and assess the potential recovery of vanadium electrolyte and associated value-added co-products from the Lac Doré project.
IGS is based in Montréal, Québec, providing metallurgical testing, process development, and ISO‑17025‑certified analytical services to the mining industry.
