Peter is very much welcomed as Chair as we continue to build and execute our corporate strategies. He is an excellent team-builder and his guidance will be critical as our growth accelerates. I would like to thank David Rhodes for his support and expertise during his time as Luca's Chair. Luca is fortunate that David will remain as a Director. Ramon has excelled on the operational front since joining Luca and will build upon this success in his new position as COO. He is a role model to the teams in Mexico and under his leadership Luca's two mines have consistently performed well. His expertise has facilitated successful optimizations at the Company's operations leading to increased production, cash flow and market performance."
