Premier intersects high-grade gold at Cove Gold Project in Nevada

Shares Issued:  138,352,462

THUNDER BAY, ON, June 28, 2012 /CNW/ - PREMIER GOLD MINES LIMITED (TSX: PG) ("Premier") is pleased to announce encouraging drill results from an initial drill program at the Helen Zone on the Company's 100% newly-owned Cove Gold Project, located in the Eureka-Battle Mountain Trend in Nevada.

The Helen Zone deposit represents one of the highest-grade undeveloped gold deposits in Nevada and remains open for expansion.  The current drill program is designed to confirm and expand mineralization within both the Upper and Lower Helen Zones.  To-date, eleven (11) holes have been completed and a twelfth is in progress with assays having been received for the first ten holes.  Impressive high-grade gold has been intersected in multiple holes.  Highlights include:

• 23.48 g/t Au across 19.81 m - or 0.69 ounces per ton (oz/t) across 65.0 feet and 17.35 g/t Au across 4.57 m (0.51 oz/t across 15.0 feet) and in hole AX-8.
• 14.42 g/t Au across 12.19 m (0.42 oz/t across 40.0 feet) in hole AX-9.
• 16.29 g/t Au across 10.70 m (0.48 oz/t across 35.0 feet) in hole AX-3.
• 12.38 g/t Au across 6.10 m (0.36 oz/t across 20.0 feet) in hole AX-4.
• 15.66 g/t Au across 3.35 m (0.46 oz/t across 11.0 feet) in hole AX-10.

"The initial drill results support our belief that the Helen Zone, within the Cove Project, has the potential to host a high-grade Carlin style gold deposit" stated Brian Morris, Vice-President Exploration for Premier.  "Drilling continues to confirm the expansion potential of the Helen Zone horizon along strike of the Cove anticline within favorable host rocks which are stratigraphically deeper than historic mine production in the Cove pit.  The favourable anticline structure within the deeper host rocks remains almost entirely untested outside of the core area.  This will be the focus of future drilling as we expand mineralization".

Nevada is one of the world's most favourable jurisdictions for mine development and the Cove Project offers substantial upside in the existing resource areas in addition to opportunities for the discovery of new high-grade gold deposits within the district.  The Cove deposit was mined (primarily by open pit) between 1988 and 2001, a period of comparatively low metal prices, producing approximately 2.3 million ounces of Gold, and more than 100 million ounces of silver.  Table 1 provides a summary of highlight assay results received from the ongoing program.

Holes AX-1 to AX-9 were drilled with reverse-circulation while hole AX-10 was drilled using core. All future holes at Helen will be drilled core from surface.  Hole AX-8 cut strong mineralization, however, the profile of initial assay results below 622 m (2,040 feet) downhole suggest groundwater encountered at and below that depth may have lead to erroneous results being returned.  As such, assays below 622 m (2,040 feet) will not be reported until Premier completes a wedge out of hole AX-8 (twinned hole) with core in order to gain a more verifiable result for this portion of the previously drilled hole.  It is important to note that hole AX-8 is located within 25 feet and 125 feet of previously drilled core holes NW-13C-A and NW-6-A, respectively.  Hole NW-13C-A intersected 27.33 g/t Au across 14.6m (0.80 oz/ton across 47.9 feet) and NW-6C-A that returned an intersection of 19.77g/t Au across 9.1m (0.58 oz/t across 30.0 feet) at a depth which may correlate to the portion of the hole planned to be redrilled.

Premier's management team believes that the Cove Project represents one of the most under-explored projects in Nevada. It is located in the Eureka-Battle Mountain Trend that is host to numerous multi-million ounce producing and past-producing mines. The property is located in close proximity to excellent infrastructure (including paved roads & power) and some work has progressed such that permitting for underground access can be advanced.

Drilling continues to expand mineralization along strike to the northwest (hole AX-11 - assays pending) and to the southeast towards the historic cove open pit (hole AX-12 - assays pending).  In addition to the Helen Zone, Premier intends to evaluate the entire property, including numerous untested and favourable structural intersections and the possible existence of skarn deposits located within ground controlled by Premier.

Total consideration for the acquisition is approximately $28 million, payable over a three year term including $8 million on closing (half of all payments are payable in shares).  Upon delivering a positive feasibility study containing a minimum of 500,000 ounces of gold or gold equivalent on the property, Newmont McCoy Cove Limited, a wholly owned subsidiary of Newmont Mining (NYSE:NEM), holds an option to enter into a joint venture by paying 250% of the sum of expenditures made on the property since March  2006 for a 51% interest.

OTHER PROJECTS

Premier holds several projects that are the subject of exploration programs in 2012.  Recently, the haulage drift in Red Lake has crossed onto the Rahill-Bonanza Project (PG 49% and Red Lake Gold Mines 51%) that is located in close proximity to Goldcorp's Red Lake Gold Mines infrastructure. A new gold horizon is being defined on the East Bay Project (PG 35% and 50% - JV with RLGM) is located on the same structural trend along strike from Rubicon Mineral's F2 Zone deposit on its Phoenix Gold Project. Several drills are active on the 100%-owned Trans-Canada Project, which is host to several deposits.  A revised resource estimate is anticipated from three separate deposits in the near future.

Premier continues to work towards the potential consolidation of the Saddle and Rain projects within the Rain Sub-district of Nevada's prolific Carlin Trend.

The acquisition of Cove and the Saddle/Rain projects represent two of several opportunities Premier is evaluating in the United States having near-term development potential and long-term exploration upside. Premier views the US as a geologically and politically attractive vehicle for future growth.
