Ms. Esper, vice-president, sustainability: In this new role, Ms. Esper will lead Jaguar's health, safety and environment (HSE) team and serve as a member of the senior leadership team, reflecting the company's strong commitment to these areas. With over 30 years of mining experience in North and South America, Ms. Esper has led major HSE and community initiatives while ensuring compliance with international sustainability standards. She holds degrees in mining engineering, safety engineering, occupational medicine and mineral characterization. Her extensive expertise will play a key role in advancing Jaguar's sustainability objectives and reinforcing its leadership in responsible mining.

Luis Albano Tondo, chief executive officer of Jaguar, commented: "We are pleased to welcome Juliana and to recognize Carla with this well-deserved promotion into key vice-president roles. Carla's extensive knowledge of our operations and her pivotal role in navigating recent negotiations with Brazilian authorities make her the ideal leader for corporate affairs. I also previously had the privilege of working with Juliana on the licensing and construction of the Kinross Paracatu expansion project, which became Brazil's largest gold mining operation. Her international experience and proven track record in sustainability and HSE will be invaluable as we continue to advance our environmental stewardship, strengthen safety performance and uphold our commitment to responsible mining. These appointments further align Jaguar's leadership structure with our long-term growth strategy and ESG [environmental, social and governance] priorities, ensuring we remain well positioned to deliver sustainable value."

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699 to 1701 of gold contaminated with iron and platinum group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class, multimillion-ounce gold deposits such as Morro Velho, Cuiaba and Sao Bento. Jaguar holds the second-largest gold land position in the Iron Quadrangle with over 46,000 hectares.
