He is a registered geo in Quebec (OGQ) and is qualified to register as a PGeo in Ontario (APGO).

JP brings deep technical expertise in structural geology, gold systems and Abitibi-focused exploration, together with a strong track record of discovery and project advancement. His experience leading exploration and development companies adds meaningful technical depth to the board as Loyalist advances its portfolio in the Timmins district. I look forward to working with JP as we continue to evaluate, prioritize, and advance our exploration and development activities."
