THUNDER BAY, ON, May 21, 2013 /CNW/ - PREMIER GOLD MINES LIMITED (TSX:PG) is pleased to announce additional high-grade results from ongoing drilling at the Company's Trans-Canada Property in Northwestern Ontario. Drilling has discovered a parallel gold-bearing horizon within 250 metres of surface and continues to confirm extensions to several horizons. New highlight intercepts include:

• 400.53 grams per tonne gold (g/t Au) across 5.0 metres (m) in hole HR156 including 2,000 g/t Au across 1.0 m drilled to upgrade resources in the deeper portion of the pit shell within the HGN-Zone.
  
  
• A new zone(s) was discovered (North Wall Zone) to the north of the primary resource area in the condemnation program. Early results include 132.32 g/t Au across 3.9 m (3.86 oz/t gold across 12.8 feet) in hole HR155; and 13.96 g/t Au across 6.0 m and 1.52 g/t across 17.0 m in hole HR157 contained within a conceptual pit shell design.
  
  
• 3.80 g/t Au across 22.0 m in hole HR142, a step out hole in the western portion of the conceptual open pit resource area.
  
  
• 20.22 g/t Au across 4.5 m in the Fortune Zone in hole HR143 drilled to upgrade resources from Inferred to Indicated within a larger conceptual open pit shell.

The Trans-Canada Property, with their multi-million ounce gold resource (technical report filed February 1, 2013), are host to four gold deposits with open pit and underground mining potential, The Hardrock Project, which hosts the largest of the four deposits, is the focus of the current drill program.

The open pit portion of the 2012 mineral resource estimate for the Hardrock Deposit was limited to a depth of approximately 200 metres. Recent scoping work suggests that the resource may be optimized by eliminating this limitation and eight (8) drills are currently active to further test this model.

The ongoing program, comprised primarily of delineation drilling at Hardrock, will upgrade inferred resources in addition to testing previously undrilled areas within the conceptual pit shell associated with the resource. Table 1 provides a summary of new assay results from step-out and infill drilling within the open pit target area.

Highlights from initial drilling include multiple intercepts of strong mineralization within the known gold horizons and the discovery of new mineralized horizons to the north of the primary resource area including the North Wall Zone (north of HGN) where appreciable mineralization (veining and rare visible gold) has been identified proximal to a gabbro rock unit.

The North Wall discovery includes multiple lenses of mineralization, locally high-grade, associated with or in close proximity to the northern gabbro rock unit. Locally, the veining associated with this new horizon contains impressive visible gold. These new horizons remain open for expansion and ongoing drilling is testing the potential of this new area.

"Hardrock continues to impress with its ongoing ability not only to provide excellent results within the known horizons, but also yielding new discoveries" stated Stephen McGibbon, Executive Vice-President of Premier. "This year's substantial drill program will advance the project towards our goal of firming up resources for future economic studies".

Work is now underway to advance Trans-Canada towards a production decision. A Preliminary Economic Assessment (PEA) is expected to be completed in Q3-2013 for the Hardrock and Brookbank deposits that will include combined open pit and underground scenarios.

The Trans-Canada Property benefits from development advantages with the Trans-Canada Highway, Trans-Canada Pipeline, and major power lines running through, or in close proximity to, the Project sites. Significant services and a skilled labour pool exist with several communities located in close proximity.
