Mr. Gray's leadership has been critical in driving the project through engineering design, community engagement, and rigorous safety and environmental standards, ensuring that each milestone was met with both efficiency and integrity.

In addition to his remarkable impact on Terronera, Mr. Gray has also played a key role in shaping Pitarrilla as Endeavour's next mine, leading initial planning and team collaboration for its development.

His principled approach, collaborative spirit and steadfast focus on safety have shaped the way we operate and strengthened our team. We are truly grateful for Don's contributions and wish him much happiness in his well-deserved retirement and the exciting adventures that lie ahead.
