IGS Study Proposes Innovative and Sustainable Development of Oka Deposit Metallurgical Tests Confirm Niobium and Rare Earths Content
Montreal, Quebec--(Newsfile Corp. - August 4, 2026) - Nio Strategic Metals Inc. (TSXV: NIO) (OTCQB: NIOCF) ("Nio" or the "Corporation"), a critical mineral exploration company, is pleased to announce the results of the metallurgical study, The sustainable and optimized development of niobium and other critical and strategic minerals (CSM) of the Oka deposit, which was prepared by IGS Impact Global Solutions ("IGS"), for the Centre technologique des résidus industriels ("CTRI") as part of the Éléments08 initiative. CTRI is a Rouyn-Noranda based applied research and technology transfer centre on industrial tailings.
In addition to confirming and characterizing the strong presence of niobium, phosphate and other rare metals, IGS provides an innovative solution to process the concentrate from the deposit in a remote location, thereby reducing the local environmental impact.
The study investigates the opportunity to maximize the recovery value of the mined concentrate by using hydrometallurgical extraction of rare earth elements ("REE"), niobium, tantalum and zirconium. IGS also recommends further tests to assess the monetization of phosphate while producing the pyrochlore concentrate, as samples of the historical resource have tested 4.29% P2O5 (see Table 1).
IGS tested 95 samples taken from historical drill cores of the S60 and HWM2 zones to create a composite sample representative of the historical resource (see Table 1). The significant presence of REE was confirmed in the zone targeted for mining. The results, summarized in Table 2, demonstrate that the total rare earth oxide ("TREO"), content is 0.507% TREO for the composite simulating that of the 2011 feasibility study (FSG) and 0.935% TREO for the composite (HGG) designated as high-grade in Nb₂O₅.
A high-grade Nb composite sample (HGG), prepared at CTRI, was sent to SGS for a mineralogical study performed using TIMA (Tescan Integrated Mineral Analyzer) and electron microprobe analysis (EMPA). Flotation test work performed on the metallurgical test composite delivered, in open circuit, a pyrochlore concentrate grading 52.75% niobium pentoxide (Nb₂O₅) at a niobium recovery of 81.14% — a substantial improvement over the historical baseline of 44.5% Nb₂O₅ at 71.7% recovery established in the 2011 feasibility work. This was achieved with a markedly simpler flowsheet.
The concentrate additionally contained 11.75% TREO — of which approximately 83% is cerium oxide (CeO₂), 9% neodymium oxide (Nd₂O₃) and 3% praseodymium oxide (Pr₆O₁₁) — together with 1.5% zirconium (Zr), equivalent to 2.0% zirconium oxide (ZrO₂), and 0.4% tantalum (Ta), equivalent to 0.49% tantalum pentoxide (Ta₂O₅). The full rare earth distribution of the concentrate is detailed in Table 3.
Michel Bourassa, founder of Soutex, commented, "these results demonstrate once again how the rock of the Oka deposit is rich in niobium and rare earths and, moreover, is amenable to various metallurgical treatment processes."
Bruno Dumais, President and Chief Operator Officer suggested that "The study points to a potential increase in the project's value by enabling a better niobium recovery; recovery of phosphate as a byproduct (historically sent to tailings); and the extraction of REE that would otherwise be disregarded and lost in the slag."
Importantly, the new approach would minimize the environmental impact of the residues as the tests demonstrated it was possible to significantly reduce the thorium and uranium contents from 2,000 and 1,000 parts per million (ppm) to 824 and 120 ppm, respectively (see Table 4). This solution innovates in its approach, as well as provides a de-risking plan to rehabilitate the tailings on the old mining site.
The Corporation looks forward to communicating on the results of the CTRI sponsored study on water management and other environmental aspects of the sustainable development of the Oka deposit.

Notes: Composite CM7-A (95 samples from 18 drill holes, zones S60 and HWM2; total mass 31,856.9 g) was assembled by IGS for the E08 metallurgical test program; assays are reported in weight percent (wt %). "Feed M7-A" is the head assay of the reference composite used in the 2011 feasibility-study test work, shown for comparison. Composite grades correspond to the mass-weighted average of the individual samples.
