Jaguar Mining Inc. has made two new additions to its senior management team. Daniel Karrqvist has been appointed to the role of chief financial officer (CFO) and Naomi Nemeth has been appointed to the newly created role of vice-president, investor relations.

Mr. Karrqvist will be responsible for overseeing all aspects of the company's financial operations, including financial strategy, reporting, treasury, tax planning and internal controls. He will play a pivotal role in optimizing capital structure, driving cost-efficiencies and ensuring robust financial systems are in place to support Jaguar's strategic growth initiatives. Additionally, Mr. Karrqvist will assume the vital role of corporate secretary, overseeing corporate governance and compliance.

Ms. Nemeth will be responsible for building and maintaining a comprehensive investor relations program, for communicating with all levels of investors on a global basis and contributing her expertise to Jaguar's aggressive business and growth strategy. Ms. Nemeth will work closely with Jaguar's chief executive officer, senior management team, Brazil staff and the company's board of directors to implement a pro-active institutional and retail shareholder program, and will begin an outreach program targeting non-traditional investor groups for both awareness and investment in Jaguar Mining.

"On behalf of the board and management of Jaguar Mining, I would like to welcome Mr. Karrqvist and Ms. Nemeth to our senior management team, who are all experienced professionals in their own fields," commented Jaguar Mining chief executive officer Luis Albano Tondo. "Mr. Karrqvist's international experience in senior financial roles in mining and other related fields will be critical in ensuring Jaguar will have the appropriate financial systems, staff and resources in place to achieve its strategic growth plan. Ms. Nemeth's extensive experience in investor relations in the mining sector, in augmenting shareholder rosters with high-quality shareholders and in keeping all shareholders informed on company progress will also contribute significantly toward the company achieving its strategic goals. We would also like to thank Marina Fagundes de Freitas for her 15 years of service, most recently serving as interim chief financial officer since May, 2025, and wish her the best of luck in her future endeavours."
