Significant Resource Increase for Panorama Open Pit Cu-Zn Project

The Panorama Mine will double the metal output of CBH, currently derived from the
Endeavor Mine in NSW, and is a key element in the Company’s expansion plans to
achieve a zinc metal equivalent production of 250 Ktpa in 2009.
The Panorama development is in the final stages of environmental approval with on-site
construction scheduled to commence in May 2008 and commissioning in late 2009. The
project is designed to mine and treat 1.5 million tonnes ore per year to produce 90 Ktpa of
zinc concentrate (55% Zn) and 80 Ktpa of copper concentrates (25% Cu).
