Rainy River Completes Buy-Out of NSR Royalty

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 4, 2009) - Rainy River Resources Ltd. (TSX VENTURE: RR.V) (the "Company") is pleased to announce that it has completed the purchase of a 3% net smelter return royalty ("NSR") held by two arm's length optionors (the "Optionors") on lands forming part of the Company's Rainy River project in northwestern Ontario. The buy-out agreement was previously disclosed in the Company's news release dated May 13, 2009.

Under the buy-out agreement, the Company has purchased the entire NSR for the aggregate one-time purchase price of $475,000 cash and 600,000 common shares of the Company (the "Consideration Shares") at a deemed value of $2.65 per share, being the volume weighted average trading price of the Rainy River common shares on the TSX Venture Exchange over the five trading days immediately preceding the day on which the TSX Venture Exchange gave written notice to Rainy River of its conditional acceptance of the transaction.

The purchase of the NSR is a continuation of the Company's strategy of improving the potential economics of its Rainy River project. In November of 2008 the Company purchased a tonnage royalty held by Nuinsco on the properties. The completion of the buy-out of the NSR royalty will result in there being no royalty burdens held by any third parties over the core properties comprising the Rainy River project.

The Consideration Shares are subject to a four-month hold period that will run from the date the shares are issued.

On behalf of the Board of Directors of Rainy River Resources Ltd.,

Nelson W. Baker, President
