THUNDER BAY, ON, June 25, 2012 /CNW/ - PREMIER GOLD MINES LIMITED (PG:TSX) ("Premier Gold" or the "Company") is pleased to announce the signing of a definitive purchase agreement (the "Agreement") regarding the purchase by its wholly-owned subsidiary, Premier Royalty Corporation ("Premier Royalty"), of a 1% net smelter return royalty (the "Royalty") on certain mining claims which comprise the Thunder Creek Deposit of the Timmins West Mine and ancillary lands, operated by Lake Shore Gold Corp. ("Lake Shore").

Pursuant to the terms of the Agreement, Premier Royalty has agreed to purchase the Royalty for cash consideration of $7,000,000 to be paid at closing and $500,000 to be paid in common shares of Premier Royalty or a resulting issuer thereof concurrent with a subsequent going public transaction of Premier Royalty.  The closing date of the Royalty acquisition is expected to occur in July and is subject to closing conditions typical for a transaction of this nature.

The Thunder Creek Deposit commenced commercial production January 1, 2012 and contains a mineral reserve estimate, reported on April 2, 2012, of 2.67 Mt at 4.86 grams per tonne gold (g/t Au) amounting to 418,000 ounces of probable mineral reserves of gold. The estimation of mineral reserves for the Thunder Creek Deposit was derived from the current base of indicated mineral resources, which was included as part of an updated mineral resource estimate released by Lake Shore on February 15, 2012 (see press release of Lake Share entitled "Lake Shore Gold Confirms Large-Scale Resource For Timmins West Mine"). The Thunder Creek Deposit mineral resources are summarized as containing 2.88 Mt at 5.64 g/t Au amounting to 521,600 ounces of indicated mineral resources of gold and 2.69Mt at 5.89g/t Au amounting to 510,000 ounces of inferred mineral resources of gold.

Abraham Drost, Chairman of Premier Royalty stated, "We have been successful at growing a significant portfolio of producing royalties as we prepare for a go-public event in the near future.  The acquisition of the Thunder Creek Deposit royalty asset adds income from a relatively new Canadian gold mine in the world class Timmins gold camp, with a capable operator in Lake Shore Gold Corp."

Premier continues to explore various alternatives for a going-public transaction of Premier Royalty, including a reverse takeover transaction.
