Meadowbank Gold Project

Cumberland is advancing Meadowbank towards open pit production of 315,000 ounces of gold per year over an 8.3 year mine life with an estimated total cash cost of US$224 per ounce based on a feasibility study1 completed by AMEC Americas Ltd. in February 2005. In June 2005, SG Corporate & Investment Banking was appointed Financial Adviser in connection with potential debt financing for the project. The Phase II exploration program on the property has commenced with drilling slated to begin at the end of July and the Company will commence construction of an airstrip at Meadowbank to support ongoing exploration efforts.

Development permitting is progressing towards final stages with operations from three, shallow open pits planned to commence in mid-2008, provided development permits and licenses are obtained in early 2006.
