Jean-Sébastien David

Jean-Sébastien David is a mining industry executive and the President and Chief Executive Officer of NioBay Metals Inc. (TSX-V: NBY, OTCQB: NBYCF), a position he has held since October 2021. With a career rooted in Quebec's resource sector, David has built deep expertise in advancing critical mineral projects from exploration through development, with a particular focus on niobium—a metal increasingly recognized for its strategic importance in steel alloys, aerospace applications, and emerging technologies.

Prior to leading NioBay Metals, David served as Chief Operating Officer at Arianne Phosphate Inc., where he played a key role in advancing the Lac à Paul phosphate mining project, one of the largest undeveloped phosphate deposits in the world. This experience gave him hands-on involvement in large-scale resource project development in Quebec's mining-friendly jurisdiction, including navigating environmental permitting, community relations with Indigenous groups, and feasibility-level engineering.

Under David's leadership, NioBay Metals has positioned itself as a significant player in the critical minerals space, with a strategic focus on niobium and tantalum. The company's flagship James Bay Niobium Project in Quebec represents one of the few potential primary niobium deposits outside of Brazil, which currently dominates global supply through CBMM's Araxá mine. This supply concentration makes NioBay's asset strategically important for North American and European supply chain security, themes that resonate strongly with resource investors focused on geopolitical risk and critical mineral demand.

David is a frequent presence at major mining investment conferences, including the Metals Investor Forum, where he engages directly with retail and institutional investors. His interviews with prominent mining journalists such as John Kaiser and Michael Fox demonstrate his commitment to transparent shareholder communication and his ability to articulate the investment thesis for critical minerals in accessible terms. He has also overseen the development of NioBay's pilot plant operations in Quebec, advancing the company toward potential production.
