CUPANI Metals Appoints Jacquelin Gauthier As VP Exploration

Toronto, Ontario – September 3, 2025 – CUPANI Metals Corporation (“CUPANI” or the “Company”) (CSE: CUPA, OTCQB: CUPIF) is pleased to announce the appointment of Mr. Jacquelin Gauthier, P.Geo., as Vice President of Exploration.

Mr. Gauthier is a professional geologist with over 40 years of experience in mining exploration. He held senior positions with Niobay Metals Inc., Trans-Siberian Gold Plc, Vior Inc., Kinross Gold Corp., Bema Gold Corp., Cambior Inc., Azimut Exploration Inc. and Noranda Inc. 

Brian Bosse, CEO of CUPANI, commented: “I am thrilled to welcome Jacquelin to the CUPANI leadership team. Jacquelin was associated with several discoveries and his knowledge of managing projects in areas with remote logistics will help move the Blue Lake project forward. His ability to convert opportunities into significant mineral assets is exactly what CUPANI wants. We spent a week together in the field; the knowledge he brought was evident immediately, while his enthusiasm grew as the opportunity became visible. Today is a great day for the company!”

Throughout his career, Mr. Gauthier has been responsible for the discovery of four economic gold deposits, working with four different teams in Canada and Russia. He also brings exploration experience in ultramafic-hosted Ni-Cu-Co-PGE environments, having recently served as VP Exploration for NorthX Nickel Corp. He led the team that discovered a new high-grade zone 300 meters from the main deposit. Mr. Gauthier graduated from the Université du Québec à Chicoutimi with a degree in Applied Science (geological engineering). He currently serves on the Mining Advisory Committee of the Autorité des Marchés Financiers (Québec) and is a member in good standing of the Ordre des Géologues du Québec.

Mr. Gauthier added:
“I am delighted to join CUPANI as Vice President of Exploration. After reviewing the available data and meeting with the Company’s technical team, I believe that the Blue Lake property has excellent potential for substantial growth and additional discoveries.  The current combined historical resource of 4.37 million tonnes grading 0.87% Cu, 0.52% Ni, and 0.84 g/t Pt+Pd or 2.28% CuEq (not NI 43-101 compliant) clearly demonstrates that the ultramafic intrusives and flows are fertile. Yet only a handful of shallow drill holes have tested the 682 km² property outside the resources area. I look forward to advancing this challenging and fascinating exploration project with Cupani’s dedicated team.”
