Rainy River Intersects 352.84 g/t (10.29 oz/t) Gold Over 6.0 Metres in Newly Expanded Beaver Pond Zone and 436.0 g/t (12.72 oz/t) Over 1.5 Metres in 433 Zone

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 18, 2010) -

Highlights

- Beaver Pond ("BP") drilling intersects 51.0 metres grading 42.5 g/t (1.24 oz/t) gold including 6.0 metres grading 352.84 g/t (10.29 oz/t) gold

- 433 Zone - 1.5 metres grading 436.0 g/t gold (12.72 oz/ton)

- 6th drill rig to be added to project

- Updated resource estimate on schedule for Q1 2010

Rainy River Resources Ltd. (TSX VENTURE:RR) (the "Company" or "Rainy") announces continued success in the 16 latest holes drilled at its 100% owned Rainy River Gold Project located in northwestern Ontario. The new high-grade zone in the Beaver Pond area was confirmed with Hole NR09-446 intersecting 51.0 metres grading 42.5 g/t (1.24 oz/t) gold including 6.0 metres grading 352.84 g/t (10.29 oz/t) gold, including 701.29 g/t (20.45 oz/t) gold over 3.0 metres. In addition, Hole NR09-422 confirmed the high-grade potential of the 433 zone during infill drilling with 1.5 metres grading 436.0 g/t (12.72 oz/t) gold. The Company is planning to mobilize a sixth drill rig to the property in order to continue its aggressive exploration of high priority targets.

Longitudinal sections and a drill hole location plan map with section lines for reference are posted on the Rainy River website www.rainyriverresources.com. Tables 1 and 2, at the end of this release, are to be read in conjunction with the text below.

New High Grade Gold Beaver Pond Discovery -- Open Down Plunge

Drill hole NR09-446 intercepted a 51.0 metre thick gold zone averaging 42.5 g/t (1.24 oz/t) gold at a vertical depth of 250 metres below surface. Hole NR09-446 has a high-grade core of 6.0 metres averaging 352.84 g/t gold (10.29 oz/t) including 701.29 g/t (20.45 oz/t) gold over 3.0 metres, surrounded by a lower grade halo that averages 0.92 g/t gold. This new intersection occurs 125 metres up-plunge from drill hole NR09-329 which intersected 29.2 metres grading 2.3 g/t gold (including 7.5 metres grading 5.46 g/t gold and 3.7 metres grading 5.69 g/t gold) and 30 metres east of drill hole NR09-402 which contained 1.34 g/t gold over 49.5 metres including 3.41 g/t gold over 4.5 metres and 3.37 g/t gold over 12.0 metres (which further included 5.64 g/t gold over 4.5 metres), defining a new higher grade core below the previously known shallow Beaver Pond mineralization (see news releases dated March 11, 2009 and December 1, 2009, respectively). This new high-grade occurrence remains untested down plunge.

433 Zone - Continuity of High Grades Developing

Drill hole NR09-422 intersected 1.5 meters of 436.0 g/t gold (12.72 ounces/ tonne) in the 433 zone at a vertical depth of 325 metres below surface. The current known strike length of the zone at this level is approximately 170 meters in an east-west direction. Drill hole NR09-422 was designed as in infill drill hole between drill holes NR08-228 (1.5 metres grading 8.8 g/t gold or 0.26 oz/t gold) and NR08-229 (1.3 metres grading 72.3 g/t gold or 2.11 oz/t gold). The high grade intercepts establish the potential for a continuous high grade area in this portion of the 433 Zone.

ODM/17 and HS Zone Drilling

Seven holes were completed in the ODM/17 and HS Zones to infill inferred gold mineralization in a continued effort to upgrade the existing resource mineralization to the indicated category. The drilling was very successful in confirming the shallow mineralization lying at the top of the ODM/17 Zone and further confirmed and added HS style mineralization between the ODM/17 Zone and 433 Zone.

HS mineralization has a potential strike length of approximately 600 metres and is semi-continuous. Widths range from 1.5 metres to 15 metres thick. The HS Zone mineralization defined in 2009 has the potential to add a significant amount of gold mineralization to the upcoming resource estimate.

2009 Drill Program - Revised Resource Estimate On Schedule

120 drill holes have been completed since January 1, 2009 on the Rainy River property and will be included in the new NI 43-101 compliant resource estimate to be completed by the end of the first quarter of 2010 by SRK Consulting Ltd.

"We are incredibly pleased with the results of the 2009 drill program and have discovered new high-grade zones at the Beaver Pond, 433 and deep ODM/17 Zones," commented Raymond Threlkeld. "The Company has also discovered through drilling the shallow South Zone in addition to confirming the grade and infilling a large portion of the open pit mineralization. We still have numerous untested targets within the known Richardson Caldera complex and the potential for further discovery is very encouraging for the future of Rainy River."

Comments

"NR09-446, surpassed in grade only by a 1.0 metre intercept of 4,158 g/t or 121.27 oz/t in 2007 in the 433 Zone in previously released hole NR07-218, has opened a new high-grade zone starting at approximately 200 metres below the surface at Beaver Pond," commented Raymond Threlkeld, President and CEO. "We are extremely excited about the potential of this zone and as a result, Rainy River will be adding a sixth drill rig to focus on this area and the high-grade found in the 433 Zone. Our geologic team at the site continues the excellent work of understanding the gold system at Rainy River and unlocking the potential."

Mineral Exploration Roundup 2010

The Company will have a booth (booth #F2) at the 2010 Mineral Exploration Roundup in Vancouver on Wednesday, January 20th and Thursday, January 21st. As well, a selection of representative drill core from the various 2009 discoveries will be exhibited in the Roundup Coreshack on Wednesday, January 20th 2010. Company geologists will be on hand to discuss the many aspects of the year's drilling successes. The high-grade drill core from hole NR09-446 will be available for viewing.

About Rainy River Resources Ltd.

Rainy River Resources is a Canadian precious metals exploration company whose key asset is the Rainy River gold project. With over CAN$20 MM 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 pre-feasibility 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.

Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results may differ materially from those in forward looking statements. Factors that could cause the actual results to differ materially from those in forward-looking statements include gold prices, results of exploration and development activities, regulatory changes, defects in title, availability of materials and equipment, timeliness of government approvals, continued availability of capital and financing and general economic, market or business conditions. The Company cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on the Company's forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail.
