Rainy River's South Zone Returns 7.83 g/t Gold Over 3.0 Metres

TORONTO, ONTARIO--(Marketwire - Aug. 26, 2010) - Rainy River Resources Ltd. (TSX VENTURE:RR) ("Rainy River" or the "Company") is pleased to announce drill results from the Rainy River Gold Project in Northwestern Ontario.

Exploration of the South Zone returned a strong intersection of 2.53 g/t gold over 24.0 metres, including 7.83 g/t gold over 3.0 metres, in drill hole NR10516 at a depth of 360 metres. This intersection lies approximately 100 metres above a hole NR07198 intersection grading 25.6 g/t gold, 184.1 g/t silver and 0.3% copper over 4.0 metres. The South Zone is largely unexplored and represents a highly prospective target approximately 300 metres south of the ODM17 Zone. It is completely open to the east and below 360 metres. At a 3.0 g/t cut-off grade and 4.0 metres minimum width, previous drilling in the South Zone has averaged 7.58 g/t over an average width of 4.4 metres. Detailed results are shown in Table 1, below.

Infill drilling in the upper limits of the 433 Zone has recently begun with encouraging results. Hole NR10523 intersected 1.56 g/t gold over 25.5 metres, including a higher grade intercept of 7.17 g/t gold over a width of 3.0 metres. Additionally, drill hole DR10524 returned an intersection of 18.0 metres grading 1.03 g/t gold at a depth of 169 metres from surface. The drill hole extension program targeting the deeper parts in the 433 zone is now complete with drill hole NR0675E intersecting 43.5 metres grading 1.08 g/t gold, including 1.5 metres grading 8.39 g/t gold.

"Our infill drilling program is off to a good start with early results confirming wide intervals of open pit grade mineralization in the shallow depths of the 433 Zone," commented Ray Threlkeld, President and CEO. "A seventh diamond drill rig has been mobilized to accelerate the infill program, designed to tighten up the hole spacing in the ODM and 433 Zones to 50 metres and 40 metres respectively. It is very exciting to see new results out of the South Zone, an area that will be receiving more drilling later this year."

About Rainy River

Rainy River is a Canadian precious metals exploration company whose key asset is the Rainy River Gold Project. With over $60 million in its treasury, the Company is well funded to conduct a dual-focused drilling program consisting of: 1) definition diamond drilling of the main gold resources in preparation for scoping and prefeasibility studies, and 2) selective diamond drill testing of high-priority gold targets defined primarily by RC drilling within the large gold system centered in Richardson Township. The Company's property is extremely well located in the southwestern corner of Northern Ontario near the U.S. border. It is accessed by a network of roads and is close to hydro-electric infrastructure. The Rainy River district has a skilled labour force and is one of the lowest-cost areas for mineral exploration and development. Ontario has low political risk and, according to the annual Fraser Institute global survey of the mining industry, has consistently ranked as one of the top jurisdictions embracing mineral development.
