Provides Trans-Canada Project Update - Focus on High Grade - Retains JDS for Preliminary Economic Assessment
Premier Gold Mines Limited (TSX-PG) is pleased to provide an exploration update for the Company's 100% owned Trans-Canada Project in Northwestern Ontario, and to announce that it has retained the services of JDS Energy & Mining Inc. to complete a Preliminary Economic Assessment (PEA). The PEA will consider a range of possible options available to Premier in assessing how best to optimize key assets in the Trans-Canada Project including the Hardrock, Brookbank, Key Lake and Kailey Deposits. The JDS team of experienced mining professionals will augment Premier's exploration expertise to provide, in 2012, a clear economic framework and vision to advance the project toward development.
While early 2011 exploration had a focus on in-fill and step-out drilling proximal to the main resource areas, the current program has three primary goals: to delineate previously discovered high-grade gold zones (HGN and F2); to expand new discoveries (TNS and North Shear); and delineating the Key Lake Deposit, with the intent of including it in Premier's next mineral resource update for Trans-Canada. Positive early results in these target areas include multiple intercepts containing appreciable visible gold. A presentation on the high-grade target zones is available on the Company's website:
www.premiergoldmines.com.
Initial follow-up drilling has returned some of the highest recorded assays, resulting in multiple ounce intercepts in several of the target areas. These zones have characteristics similar to the high-grade past producing Little Long Lac (600,000 ounces gold produced at a grade of 11.7 g/t) and Leitch (847,900 ounces gold produced at a grade of 31.5 g/t) Gold Mines located on the Trans-Canada Project. Highlights from recent drilling include:
- 251.0 grams per tonne gold (g/t Au) across 1.0 metres (m) or 7.32 ounces per ton (oz/t) across 3.3 feet (ft) in up-dip expansion drilling in the F2 Zone.
- 28.78 g/t Au across 3.5 m (0.84 oz/t across 11.5 ft) drilling down-plunge in the HGN Zone.
- 44.39 g/t Au across 5.3 m (1.29 oz/t across 17.4 ft) in the recently discovered TNS Zone.
- Veining and mineralization intersected in the North Shear discovery horizon (assays pending).
"The potential of the Trans-Canada project to host several different styles of mineralization including significant high-grade zones has been demonstrated since the acquisition of the Hardrock Property in 2008." stated Ewan Downie, President and CEO of Premier. "With our recent acquisition of Goldstone Resources, we now have more than 60 kilometres of favourable geology to explore outside of the three deposits that are the subject of current drilling."
F2 ZoneThe F2 Zone is located in close proximity below the historic F-Zone mine workings. The results from drilling reflect the follow-up to a new discovery that was made on the bottom level of the historic Hardrock Mine just prior to closure in 1968. The F2 horizon is characterized by parallel narrow-vein zones with strong mineralization and frequent visible gold.
Initial drilling (2009) in this horizon returned intercepts of 7.21g/t Au across 3.0 m (0.21 oz/t across 9.8 ft) and 121.00 g/t Au across 1.5 m (3.53 oz/t across 4.9 ft) in hole MM051, and 17.70 g/t Au across 1.5 m (0.52 oz/t across 4.9 ft) and 8.25 g/t Au across 1.5 m (0.24 oz/t across 4.9 ft) in hole MM073.
The first follow-up hole completed in 2011 (MM204) has returned multiple high-grade intercepts including 6.83 g/t Au across 3.5 m (0.20 oz/t across 11.5 ft) and 251.00 g/t Au across 1.0 m (7.32 oz/t across 3.3 ft). Table 1 provides a summary of significant results in the F2 Zone.

HGN ZoneThe High Grade North (HGN) Zone is located immediately north of the historic mine workings and was discovered in 2009 while drilling off the EP-Zone open pit. The discovery hole contained appreciable visible gold and returned an impressive
1,141.50 g/t Au across 2.0 m (33.29 oz/t across 6.6 ft).Previously drilled holes in the EP-Zone are being extended to test the down-plunge extension of this horizon. The first three holes drilled during the current program (OR015, EP149 and EP152) have all returned visible gold. Assay results have been received for two of these holes with composite intervals of
17.80 g/t Au across 1.0 m (0.52 oz/t across 3.3 ft) in OR015 and 28.78 g/t Au across 3.5 m (0.84 oz/t across 11.5 ft) in EP149 -- assays for additional holes remain outstanding. Table 2 provides a summary of significant results in the HGN Zone.

TNS ZoneThe Tenacity South (TNS) Zone was discovered in 2011 while exploring for potential gold zones parallel to the historic mine workings. A mineralized shear zone was discovered to the south of Hardrock containing high-grade intercepts including
37.49 g/t Au across 2.1 m (1.09 oz/t across 6.9 ft) in HR053 and 10.89 g/t Au across 10.0 m (0.32 oz/t across 32.8 ft) in HR054.Follow-up drilling has defined pods of high-grade mineralization within this target horizon with results that include
44.39 g/t Au across 5.3 m (1.29 oz/t across 17.4 ft) in HR058, the highest grade intercept to-date in this horizon. Table 3 provides a summary of significant results in the TNS Zone.

North Shear HorizonThe North Shear Horizon was discovered while drilling a previously untested area between the Hardrock and Little Long Lac Mines on the Property. A strong looking, mineralized, shear structure was intersected in holes drilled 250 metres apart and that assayed 6.15 g/t Au across 2.8 m (0.18 oz/t across 9.2 ft) and 4.30 g/t Au across 2.3 m (0.13 oz/t across 7.5 ft). Follow-up drilling is now underway to examine the potential of this horizon to host resources.
The Trans-Canada Project is host to several past-producing mines which collectively produced more than 4 million ounces of gold from depths within 600 metres of surface between 1938 and 1968, and several deposits that are being explored by Premier including the Hardrock Deposit. The Hardrock Deposit is host to a NI43-101 compliant mineral resource estimate that was completed by Micon International Limited earlier in 2011. The estimate is based on drilling completed up to February 28, 2011 on multiple near surface and deeper zones, many of which remain open for expansion and are the subject of the ongoing drill program. The Trans-Canada Project 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 site. Significant services and a skilled labour pool exist with several local communities.
Highlights of the Hardrock Project mineral resource estimate are set out in Table 4 below. They have been subdivided into potentially underground or open pit mineable resources and reported using different cut-off grades.

- Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues.
- The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.
