NiobiumX Mining Inc. Commences Trading on the Canadian Securities Exchange Under the Symbol "NIOX", Completing Its Transition to a Niobium and Rare Earth Exploration Company Focused on Quebec's Saguenay Region
VANCOUVER, BC / ACCESS Newswire / July 29, 2026 / NiobiumX Mining Inc. (CSE:NIOX)(OTCQB:AFXLF)(FSE:O5K) ("NiobiumX" or the "Company"), formerly Arctic Fox Lithium Corp., is pleased to announce that its common shares commenced trading on the Canadian Securities Exchange under the Company's new name and the ticker symbol "NIOX" at the opening of markets on July 17, 2026. The Company also announces that it has entered into marketing services agreements with Altura Media Co Inc. and Connect 4 Marketing Ltd., and has granted restricted share units to certain consultants.
The name change completes the Company's strategic repositioning from lithium exploration in the James Bay region to niobium and rare earth element ("REE") exploration in the Saguenay region of Quebec, following the Company's acquisition of the Shipshaw Property earlier this year.
The Company's shares continue to trade on the OTCQB Venture Market under the symbol "AFXLF" and on the Frankfurt Stock Exchange under the symbol "O5K".
Key Highlights
New Symbol Live on the CSE: Common shares trade under "NIOX" effective July 17, 2026, completing the Company's repositioning from lithium to niobium and rare earth elements.
District-Scale Land Position: The Company's activity is now directed at the Shipshaw Property, a 48-claim, 2,686-hectare niobium and rare earth property in Quebec's Saint-Honore carbonatite district.
Immediately Adjacent to a Producing District: The Property's nearest claim boundary lies less than two kilometres from the producing Niobec mine, North America's only operating niobium producer
A Concentrated Global Supply Picture: Niobium is a designated critical mineral in Canada, the United States, the European Union and Australia, and the substantial majority of world supply is produced in a single country. 1
Government of Quebec Characterization: The Shipshaw carbonatite is one of only five niobium-rare earth carbonatite systems characterized by Geologie Quebec in metallogenic bulletin BM 2024-02.2
Marketing Services Agreements: The Company has engaged Altura Media Co Inc. and Connect 4 Marketing Ltd. to provide digital marketing and investor awareness services under six-month agreements.
"The new name states plainly where we are putting our capital," said Kirby Renton, President and Chief Executive Officer. "Shipshaw sits in one of very few districts in North America with a demonstrated niobium endowment, next to the only producing niobium mine on the continent. Our near-term priority is to get modern geophysics over ground that has not been properly surveyed in fifteen years."
Why Now: A Critical-Minerals Story
Niobium is a designated critical mineral in Canada, the United States, the European Union and Australia, valued for the strength it adds to steel and the superalloys used in pipelines, transport, energy and defence.3 Global supply is among the most concentrated of any strategic metal: the substantial majority of the world's niobium is produced in a single country, Brazil, and the Niobec mine in Quebec is the only significant primary niobium producer outside it1. That is the backdrop against which NiobiumX is advancing Shipshaw.
The Niobec mine has been in commercial production since 1976 and was acquired by a consortium led by Magris Resources Inc. from IAMGOLD Corporation in January 2015 for total consideration of approximately US$530 million4.
The Shipshaw Property
The Shipshaw Property, which the Company acquired under an asset purchase agreement that closed on February 19, 2026, comprises 48 mineral claims totalling 2,685.73 hectares in the Saguenay region of Quebec, in the Saint-Honore carbonatite district that also hosts the producing Niobec mine. The Shipshaw carbonatite was recently selected by the Government of Quebec, in metallogenic bulletin BM 2024-02, as one of only five niobium-rare earth carbonatite systems characterized along the Waswanipi-Saguenay corridor.2 The Property does not host a mineral resource or mineral reserve estimate. The Company will provide a detailed overview of the Property, the Government of Quebec characterization, and its planned exploration program in a series of forthcoming news releases.
