I look forward to serving in an advisory capacity to the Board, and participating in the exciting future ahead for the Company.”

“Our commitment to our vision to be a leading low cost gold producer focused on growth in North America will not waver. Our focus continues to be on maximizing shareholder value and delivering solid performance,” said Mr. Perry. “I would like to thank the Board for their confidence in me and look forward to their ongoing support and guidance. I am excited to accept this opportunity and look forward to continuing to work with the Board and the talented AuRico team to deliver on our strategic objectives.”
