Cameron McCall, President and Executive Chairman of Macarthur Minerals commented:

"A key focus of Macarthur over the next 12 months is the identification of key strategic partners to advance the Lake Giles Iron Project to the delivery phase. Over the course of the past 8 months, whilst the Feasibility Study was under development, Mr Moon in Korea, Macarthur's Board and Eddie Sugar (EAS Advisors New York) have been fielding enquiries from interested parties. It is fair to say, all interested parties were waiting on the Feasibility Study results to catalyse any detailed evaluation of the opportunities presented by the Lake Giles Iron Project. This Sub-Committee now draws together these intentions in a co-ordinated fashion and signals the commencement of the Company's delivery phase of the Lake Giles Iron Project. "

On behalf of the Board of Directors, Cameron McCall, Executive Chairman
