100% undivided interest in the Granduc Property," commented Mr. Mike
Sylvestre, President & COO of Castle Resources. "The Granduc is a
significant copper asset with excellent infrastructure in place. It is

the down dip extent of the historical deposit, then determine the
economic feasibility of the project with the aim of ultimately
redeveloping the mine."
