Canada Zinc Metals (formerly known as Mantle Resources), is a mineral exploration company focused on unlocking the potential of a future long life mining district in the low-risk development environment of British Columbia, Canada. Canada Zinc Metals is the dominant land holder in a prolific mineral belt called the Kechika Trough which hosts in excess of 80 million tonnes of base metal resources. The Company has two 100% owned key projects: Akie (hosting the Cardiac Creek deposit) and Kechika Regional (which has significant blue sky potential).

In April, 2008, the Company announced an initial inferred mineral resource estimate for the Cardiac Creek deposit of 23.6 million tonnes grading 7.60% zinc, 1.50% lead and 13.0 g/t silver. This benchmarked the existence of large, high-grade, mineral deposit which remains open in all directions.  Subsequent exploration activity in 2008 has expanded the mineralized zone at Cardiac Creek and has discovered new styles of mineralization not previously seen in the district that indicate possible new sources of even higher grades.
