Montreal, Quebec – February 26, 2026 — NiobiumX Corp. (“NiobiumX” or the “Company”) is pleased to announce the appointment of Dr. Alexandre Dupont, PhD, to its Technical Advisory Board. Dr. Dupont brings more than 25 years of experience in carbonatite geology and critical mineral exploration.
Dr. Dupont has worked on numerous niobium, rare earth element, and alkaline intrusive projects globally, including several carbonatite-hosted deposits in Canada, Brazil, and Africa. His expertise will support NiobiumX as it advances exploration across its prospective land package in Quebec.
“Dr. Dupont’s experience with carbonatite systems and critical mineral deposits will be invaluable as we move forward with our exploration strategy,” said Kirby Smith, CEO of NiobiumX. “NiobiumX is building a world-class technical team focused on identifying new sources of niobium in one of the most prospective geological environments for the metal.”
NiobiumX is focused on advancing exploration for niobium within Quebec’s established niobium district. Carbonatite complexes, which are the primary host for niobium mineralization globally, remain one of the most prospective geological targets for new discoveries.
The Company believes that combining experienced geological leadership with modern exploration techniques will significantly enhance its ability to generate high-quality drill targets.
Dr. Dupont will work closely with NiobiumX’s technical team to support geological interpretation, exploration strategy, and the identification of priority targets across the Company’s portfolio.
Niobium plays a critical role in strengthening steel and enabling advanced materials used in infrastructure, energy systems, and aerospace applications. Despite its importance, global niobium production is highly concentrated, creating an opportunity for new discoveries in stable mining jurisdictions.
NiobiumX aims to help address this supply challenge by advancing exploration in Quebec, a region recognized for its strong mining infrastructure and supportive regulatory environment.
NiobiumX is a Canadian mineral exploration company focused on discovering and developing niobium resources. The Company is advancing projects located in Quebec, Canada — one of the world’s leading mining jurisdictions and home to the producing Niobec niobium mine.
NiobiumX is committed to building a leading niobium exploration platform focused on securing future supply of this strategic critical mineral.
