Tavi Costa is a macro investor and mining entrepreneur, and the founder and chief executive officer of Azuria Capital. His work is grounded in a differentiated macro framework focused on capital cycles, hard assets and global imbalances, with a record of consistently identifying major macro trends ahead of the broader market. His research reaches millions of readers globally, including institutional investors and policymakers who closely follow his insights. He is the founding shareholder of San Cristobal Mining, following the leveraged acquisition of one of the world's largest silver mines, now a cornerstone asset in the global precious metals industry. Mr. Costa is a frequent contributor to major financial media, including the Fox Business, The Wall Street Journal, Barron's and Bloomberg, and has presented his research at the International Monetary Fund.

Chief executive officer Mike Bennett commented: "We are extremely pleased to welcome Mr. Costa to the board of directors. Tavi's wide experience in mining finance together with his deep knowledge of the capital markets, and his wide network of industry contacts and investors, will be invaluable to the company as we continue to expand and advance the Cajueiro gold district in Brazil."

Tavi Costa, newly appointed director, added: "I'm pleased to be joining the board of Altamira Gold at a compelling stage for the business. The 43-101 resource at Cajueiro1 anchors the current value, with significant upside across the broader Alta Floresta gold belt land package. Positioned in Brazil, the company stands to benefit from the structural economic shift under way across Latin America. My goal is to be a value-add investor and director -- helping the business across all fronts, from key capital decisions to unlocking the full potential of its existing resource base and its significant exploration upside."

The company also announces that Ioannis Tsitos has stepped down from the board of directors to pursue other business interests. The board thanks Mr. Tsitos for his contributions and for his dedicated service over the past nine years, and wishes him continued success in his future endeavours.

About Altamira Gold Corp.

The company is focused on the exploration and development of gold projects within western central Brazil, strategically advancing four projects spanning over 100,000 hectares within the prolific Juruena gold belt -- an area that has historically yielded over six million ounces of placer gold. The company's advanced Cajueiro project contains two gold deposits. Continuing exploration and fieldwork at Cajueiro indicate the presence of multiple hard rock gold occurrences, traceable from historical alluvial gold production, highlighting the region's exceptional gold endowment and potential scalability. With two independently established mineral resources, a highly prospective geological setting and a record of significant discoveries, the company is well positioned to unlock further value across its extensive land package.
