"Kathy is a talented executive who brings a wealth of financial management experience in both the global mining and chemical industries," Casey continued. "I am confident that her deep knowledge in both sectors, as well as her work in international financial markets will help drive Tronox's strategic vision of growth and profitability. The fact that she and Jean-Francois were colleagues at Rio Tinto gives us confidence that they have an already established good working relationship that will help each of them become effective in their roles with us more quickly."
