About the Akie Property

The Akie zinc-lead property is situated within the southern-most part (Kechika Trough) of the regionally extensive Paleozoic Selwyn Basin, one of the most prolific sedimentary basins in the world for the occurrence of SEDEX zinc-lead-silver and stratiform barite deposits.

Drilling on the Akie property by Inmet Mining Corporation during the period 1994 to 1996 and by Mantle in 2005, 2006 and 2007 has identified a significant body of baritic-zinc-lead SEDEX mineralization (Cardiac Creek deposit). The deposit is hosted by variably siliceous, fine grained clastic rocks of the Middle to Late Devonian ‘Gunsteel’ formation. The Company recently filed a NI 43-101 report supporting the estimated inferred resource of 23.6 million tonnes grading 7.6% Zn, 1.5% Pb and 13.0 g/t Ag (at a 5% Zn cut off grade). The complete NI 43-101 technical report, titled “Geology, Diamond Drilling and Preliminary Resource Estimation, Akie Zinc-Lead-Silver Property, Northeast British Columbia, Canada ”, dated May 30, 2008, can be viewed on SEDAR.

Two similar deposits, Cirque and South Cirque, located some 20 km northwest of Akie and owned under a joint venture by Teck Cominco and Korea Zinc, are also hosted by Gunsteel rocks and have a combined geologic inventory in excess of 50 million tonnes.

The Akie property is road accessible year round from Mackenzie and Prince George , and exploration and other activities are supported by a 50 person, all-weather trailer camp situated a short distance from the Cardiac Creek drill area.

The TSX Venture Exchange has neither approved nor disapproved the contents of this press release.
