NioBay Achieves ~99.6% Niobium Oxide (Nb2O5) and 99.98% Tantalum Oxide (Ta2O5) in the manufacture of final oxides from Crevier

Niobay Metals Inc. (NBY) announced the successful purification of niobium and tantalum oxides from its Crevier Project, achieving approximately 99.6% Nb2O5 and 99.98% Ta2O5 purity. The calcination process was conducted at temperatures up to 1050°C at SGS Canada facilities in Quebec and Ontario. These results follow previous metallurgical and hydrometallurgical phases, demonstrating a clear technical pathway to high-purity final oxides.

Management highlighted that the Crevier project could be dedicated exclusively to producing niobium oxide for battery and superalloy manufacturers, citing positive technical and economic parameters. The project is located approximately 50 km north of Girardville, Quebec, within the Nitassinan territory of the Pekuakamiulnuatsh First Nation. Project ownership is held 80.18% by Niobay Metals Inc. and 19.82% by Niobec Inc. (Magris Performance Materials).

Niobay Metals Inc. (NBY) released results on August 4, 2026, marking an incremental step in its metallurgical roadmap. The findings build directly on pilot-scale results from April 2026, which showed 70% recovery and 75.8% purity, as well as the February 2026 Mineral Resource Estimate of 16.3Mt measured.

Achieving purities of approximately 99.6% and 99.98% meets potential customer specifications for battery and superalloy markets, de-risking the technical case for downstream processing. The news aligns with the company's stated progression from bulk sampling to pilot testing and final oxide production.

While the results do not immediately alter financial projections, capital requirements, or near-term cash flow, they strengthen the long-term commercial thesis. The development confirms previously announced metallurgical targets rather than introducing unexpected upside or a paradigm shift.

Niobay Metals Inc. (NBY) is a Canadian junior explorer and developer focused on critical minerals, specifically niobium and tantalum. Its flagship asset is the Crevier Niobium and Tantalum Project in Quebec, where the company holds an 80.18% interest, with Niobec Inc. retaining the remaining 19.82%. The project is positioned to supply high-purity niobium oxide for the battery and superalloy sectors, aligning with global clean energy and advanced manufacturing demands.

The company also owns the James Bay Niobium Project in Ontario. In October 2025, Niobay Metals received a three-year exploration permit for the site, enabling the resumption of drilling that had been suspended since March 2022. Management is led by Jean-Sébastien David, P.Geo., President and CEO, with a technical advisory committee that includes SGS metallurgists and Indigenous affairs advisors.
