Andina Copper Corp. has appointed Joseph Salas as vice-president, exploration, and Gustavo Zulliger as principal consulting geologist, adding significant technical expertise and extensive regional experience to the company's executive and technical teams.

Mr. Salas -- vice-president, exploration

Mr. Salas is a Peruvian national geologist with over 30 years of experience across Latin America, specializing in copper-gold porphyry systems, epithermal systems and VMS (volcanogenic massive sulphide) deposits.

Most recently, Mr. Salas served as Atico Mining's vice-president, exploration, playing a pivotal role in the growth and expansion of the El Roble VMS mine in Choco, Colombia, and the La Plata VMS deposit in Ecuador. Previously, he held senior exploration roles with Barrick exploring for copper-gold porphyries in Colombia and Ecuador. In these roles, he gained extensive regional operational and technical experience directly applicable to Andina Copper's Cobrasco project, also located in Choco.

Working closely with the chief executive officer and board, Mr. Salas will lead the company's technical team and exploration activities across the portfolio and play a key role supporting the company's commitment to disciplined business development.

"I am confident and excited about the quality of projects Andina Copper has developed, and I look forward to being part of the next phase of the company's growth," stated Mr. Salas, vice-president, exploration.

Mr. Zulliger -- principal consulting geologist

Mr. Zulliger is an Argentine national with more than 30 years of international mineral exploration experience and is widely recognized as a leading South American porphyry copper specialist. He is a published author in the Journal of South American Earth Sciences, a long-standing member of the Society of Economic Geologists and a qualified person.

Most recently, Mr. Zulliger served as exploration director at McEwen Copper. Previously, he held vice-president and director-level exploration roles across several Ivanhoe Group companies, including Kaizen Discovery, Cordoba Minerals and the Maaden-Ivanhoe joint venture in Saudi Arabia. He has also held senior technical and leadership positions with Antofagasta Minerals, Rio Tinto and BHP.

Mr. Zulliger has worked extensively across the Americas and other international jurisdictions, leading and reviewing exploration programs from grassroots through to advanced-stage projects. His experience includes direct involvement in the discovery, evaluation and advancement of several significant porphyry systems and project acquisitions. Notably, he has held senior technical and leadership roles across the Argentine Andes, contributing to major porphyry systems such as Altar, Los Azules, Taca Taca and Rincones de Araya, located proximal to Andina Copper's Piuquenes project.

Working closely with the chief executive officer and vice-president of exploration, Mr. Zulliger will support the design and execution of high-impact exploration programs, advise on the technical positioning of the company's value proposition for potential strategic partners, and support the company's continuing business development.

"I'm excited by the quality of projects Andina Copper is currently drilling as well as its exploration pipeline, and I look forward to supporting the company during this exciting next phase," stated Mr. Zulliger, principal consulting geologist.

Joseph van den Elsen, president and chief executive officer, commented: "We are delighted to welcome Joseph and Gustavo to the Andina Copper team. Their combined technical expertise and regional operational experience will be invaluable as we enter a catalyst-rich period with strong, exploration-driven news flow being generated across all three of our projects. Drill bit exploration continues at pace at Piuquenes and Cobrasco, and follow-up exploration will shortly commence at Mantau. With significant concurrent programs running across our highly compelling project portfolio, 2026 promises to be an exciting time for Andina Copper shareholders."
