“As shareholders are aware, prior to assuming the role of MD of Mantle I held the position of Project Manager
responsible for development of Exergen, seconded from Thiess and reporting to the Chairman of Thiess and
the Board of Exergen. During that time I developed a knowledge and belief in the technical and commercial
robustness the Exergen CHTD technology, and having reviewed this opportunity for its applicability and
suitability for this project with Mantle I am excited at the potential for both companies.”
