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 Mantle in 2005 and 2006 has identified a significant body of baritic SEDEX mineralization (Cardiac Zone) containing average combined zinc+lead contents in excess of 10%. The deposit is hosted by variably siliceous, fine-grained clastic rocks of the Middle to Late Devonian ‘Gunsteel formation’.

Three similar deposits, Cirque, South Cirque and Driftpile (all owned by Teck-Cominco), with a combined geologic inventory in excess of 65 million tones averaging approximately 10% combined zinc-lead, occur in ‘Gunsteel’ rocks to the northwest of the Akie deposit.

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