NORTHISLE ANNOUNCES APPOINTMENT OF DR. PABLO MEJIA HERRERA AS VICE PRESIDENT EXPLORATION

NorthIsle Copper and Gold Inc has appointed Dr. Pablo Mejia Herrera, PGeo, as vice-president, exploration. Robin Tolbert, PGeo, has moved to a newly created position as chief geoscientist and will work closely with Dr. Mejia and the exploration team on the continuing exploration activities at the North Island project.

Sam Lee, president and chief executive officer of NorthIsle, commented: "We are very pleased to bring Pablo onto our team to succeed Robin as vice-president of exploration. We have added tremendous value through exploration over the past five years and will greatly benefit from Pablo's deep knowledge in mineral exploration and his leadership in disruptive AI [artificial intelligence] technology that has contributed to major mineral discoveries globally. Combined with Robin's extensive porphyry knowledge and our excellent exploration team, NorthIsle is favourably positioned for continued success."

With more than two decades of global experience in mineral exploration, Dr. Mejia serves as a geoscientist who focuses on copper, gold and nickel. He directed exploration activities throughout many mining districts with a focus on magmatic sulphide systems, along with IOCG (iron oxide copper/gold) deposits as well as porphyry copper systems and shear-zone-related gold deposits. Dr. Mejia was previously vice-president of exploration at Ero Copper Corp., where he led both greenfield and brownfield exploration programs in Brazil, which resulted in major discoveries and improved geological interpretations, driving resource growth. Most recently, he has worked as a consultant, focusing on advancing AI applications for exploration in collaboration with Stanford University and Ero Copper Corp. Additionally, he has continued to advise Ero Copper on target generation for its key assets. Dr. Mejia obtained his Masters and PhD in geosciences from the University of Lorraine in France and holds a professional geoscientist (PGeo) registration in British Columbia, Canada.

Dr. Mejia commented: "I am excited to join the NorthIsle team and lead a multidisciplinary effort to advance the North Island assets. This project stands out as a highly promising copper-gold porphyry belt with exceptional potential. I look forward to building on the strong team already in place, integrating the extensive existing data and applying a comprehensive interpretation to further enhance discovery rates and drive exploration success."

2025 exploration overview

NorthIsle is currently in the final stages of preparing its 2025 exploration program. The fully financed $7-million program will be focused on enhanced understanding of higher-grade, higher-margin potential in the vicinity of Northwest Expo and West Goodspeed, an area that is now being identified as the Northwest corridor. To date, the discoveries in this area have improved overall project resource grade and margin and have generally been near surface, presenting a compelling option for further improving the North Island project. The company expects to announce further details on the program once available.
