Metallic Minerals (TSX VENTURE:MMG)(OTC PINK:MMNGF)(Metallic Minerals or the Company) is pleased to announce that it has acquired 100% interest in 53.5 square kilometres (km2) of new mineral properties in the Keno Hill silver district of Canada’s Yukon Territory.

These properties have potential to host Keno type high-grade silver-lead-zinc mineralization and are adjacent to, or contiguous with, Metallic Minerals’ Keno Silver property and Alexco Resource Corp’s Keno Hill properties and bring the Company’s total district land position to 166 km2.

Greg Johnson, Metallic Minerals’ Chairman & CEO stated:

We are very pleased to have been able to acquire these additional prospective properties in the high-grade Keno Hill silver district, which has produced over 200 million ounces of silver.

With over 100 years of mining history in the Keno Hill silver district, the geological controls are well-understood and, in recent years, the team at Alexco has made several major new discoveries through their systematic exploration in the district along the known mineralized structural corridors.
