NiobiumX Mining Inc. is a Canadian junior mineral exploration and development company focused on the identification, acquisition, exploration, and evaluation of critical minerals and energy metals properties in Canada. The company specializes in mineral asset exploration targeting clean energy, advanced technology, and high-performance industrial supply chains, with its core property portfolio comprising: the Shipshaw Property, a flagship 2,686-hectare niobium and rare earth elements (REE) exploration project consisting of 48 mineral claims in the Saint-Honoré carbonatite complex of the Saguenay region of Quebec; the Pontax North Lithium Property, prospective for lithium-bearing spodumene pegmatites situated within the James Bay lithium district of northern Quebec; the Kana Lake Lithium Property, located in the James Bay region of Quebec; and the Spius Property, a porphyry copper exploration asset situated in the Nicola and New Westminster Mining Divisions of southwestern British Columbia, in which the company holds an option agreement to earn an interest. NiobiumX Mining Inc. targets raw critical mineral discoveries intended for end markets including high-strength low-alloy steel manufacturing, aerospace and defense superalloys, advanced electronics, superconducting magnets, and next-generation battery technologies. In recent operational and corporate developments, the company executed a major strategic expansion into the niobium and rare earth elements sector through the acquisition of the Shipshaw Property located adjacent to North America's only operating niobium mine. To reflect this strategic pivot, the company changed its name from Arctic Fox Lithium Corp. to NiobiumX Mining Inc. in July 2026 and began trading under the ticker symbol NIOX on the Canadian Securities Exchange (CSE), with additional listings on the OTCQB (NIOXF) and the Frankfurt Stock Exchange (O7D0). Furthermore, the company initiated a two-phase technical exploration program at the Shipshaw project comprising historical core re-assaying and follow-up diamond drilling, and appointed professional exploration geologist Erik Sehn to its Board of Directors in September 2026 to oversee technical and project development strategies. Originally incorporated in 2013, NiobiumX Mining Inc. is headquartered in Vancouver, British Columbia, Canada.
