Premier Gold Mines Limited (TSX-PG) is very pleased to announce that an updated National Instrument (NI) 43-101 compliant mineral resource estimate has been completed by Micon International Limited for its 70%-owned Hardrock Project, located near Geraldton in Northwestern Ontario. The estimate reports a significant increase in all categories, including the use of a measured category for the first time and is summarized in Table 1. All final data available as of February 28, 2011 were used in completing the estimate. In 2010, there were 114,000 metres of drilling at Hardrock on multiple near surface and deeper zones. Many of these remain open for expansion and are the subject of an ongoing drill program in 2011.

Highlights of Micon's new mineral resource estimate include:

• A 269% increase in Measured and Indicated resources to 2.5 million ounces.
• A 164% increase in Inferred resources to 1.1 million ounces.
• A 30% increase in the "potential open pit" Measured and Indicated resource grade to 2.37 grams per tonne gold (g/t Au).
• A 37% increase in the "potential open pit" Inferred resource grade to 2.48 g/t Au.
• Some 40% of the Measured and Indicated resource ounces are categorized as "Measured."
• A "Whittle-Pit" analysis suggesting a strip ratio on potential open pit mineral resources of 2.1 to 1.
• The Kailey ("potential open pit") Deposit resource is included and contains 127,000 ounces of Measured and Indicated Resources at 1.57 g/t Au and 10,000 ounces of Inferred resources at 1.48 g/t Au.

Premier President & CEO, Ewan Downie states "This robust mineral resource estimate at Hardrock is the result of a great team effort and 24 months of aggressive exploration. This resource estimate is in line with our goal of developing a significant deposit, potentially capable of mid-tier gold production. With 8 drills currently active on the Property and several zones still open for expansion, we continue to see considerable upside in this resource."

In 2011, more than 70,000 metres of drilling is planned to continue to expand and upgrade these resources. Additionally, regional exploration in the search of the "next one" in the Hardrock area is underway. The near-term goal is to secure permits for Advanced Exploration, which will include de-watering of the historic mine workings and the construction of an Exploration Ramp. The ramp will allow underground drilling to be completed in support of a preliminary economic assessment to evaluate the potential for a future mining operation to be established at Hardrock.

The mineral resources estimated for the Hardrock project (both the Hardrock and Kailey Deposits) are set out in Table 1 below. They have been subdivided into potentially underground or open pit mineable resources and reported using different cutoff grades.

1.     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.

2.     The mineral resources were estimated using a block model with parent blocks of 25x30x10 sub-blocked to a minimum size of 5x3x2 and using Inverse Distance Cubed methods for grade estimation. A total of 12 individual mineralized domains were identified and estimated using an average top cut of 48 g/t Au. For a "potential open pit" mineral resource a cut-off grade of 0.83 g/t Au is based on a Whittle optimized pit shell and a mining recovery of 100%. For potential underground mineral resources a cut-off grade of 2.80 g/t Au and an assumed mining recovery of 100% outside of the potential open pit mining areas was used.

3.     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.

4.     The mineral resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council November 27, 2010.

Tables 3 and 4 below, present the tonnes and grades from the block model used for the Mineral Resource estimate at a range of cut-off grades in order to demonstrate the sensitivity of the estimates. The cut-off value of 0.83 g/t Au for "potential open pit" and 2.80 g/t Au for deeper, potential underground mineralization, was derived using the parameters listed in Table 2 below.

Hardrock Deposit

The Hardrock Project is located approximately 4 kilometres south of the town of Geraldton, Ontario and is host to several past-producing mines which collectively produced more than 3 million ounces of gold from depths primarily within 600 metres of surface between 1938 and 1968. Underground resources are located proximal to and below the historic mine workings. New discoveries including the High-Grade North Zone and the F2 East Zone will be the focus of the planned underground drill program. The current Mineral Resource estimate uses 11 identified mineralized domains to develop a combination potential open pit and underground mineral resource. The Hardrock 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 communities located within 30 kilometres. The Hardrock Project is operated under a joint venture with Goldstone Resources Inc. (TSX:GRC).

Kailey Deposit

The Kailey deposit is located about 2 km north of the Hardrock deposit at the location of the former historically operated Little Long Lac gold mine. The Kailey mineralized zone is a small lower-grade potential open pit mineral resource.

Resource Statement

The mineral resource estimates in this press release use the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by CIM Standing Committee on Reserve Definitions and adopted by CIM Council on November 27, 2010. The mineral resource estimates provided in this report are classified as "measured", "indicated", or "inferred" as defined by CIM.

According to the CIM definitions, a Mineral Resource must be potentially economic in that it must be "in such form and quantity and of such grade or quality that it has reasonable prospects for economic extraction". For the Hardrock deposit, a gold cut-off grade was assigned based on economic assumptions and was used in the resource estimations. Table 2 above shows the economic parameters used in the gold cut-off grade calculation.

The estimated costs for the Hardrock deposit, mined as an open pit, are $3.00 + $20.00 + $1.00 = $24.00/t milled which works out to an estimated gold cut-off of 0.83 g/t. The estimated costs for the Hardrock deposit, mined as an underground, are $60.00 + $20.00 + $1.00 = $81.00/t milled which works out to an estimated gold cut-off of 2.80 g/t. Resources reported in this press release use an estimated potential open pit gold cut-off of 0.83 g/t and for a potential underground use 2.80 g/t.

The mineral resource estimate presented in Table 1 is effective as of 5 April 2011. The mineral resources listed in Table 1 were estimated by Sam J. Shoemaker, Jr., M.AusIMM, and Registered Member-SME. Mr. Shoemaker is a QP as defined in NI 43-101 and is independent of Premier Gold.
