- Resource Estimate on Schedule - 122 Drill Holes Added from 2009 Drilling Program

Rainy River Resources Ltd. (the "Company" or "Rainy") announces the receipt of final assays from the 2009 drill program.

Longitudinal sections and a drill hole location map with section lines for reference are posted on the Rainy River website www.rainyriverresources.com.

New-High Grade Gold Mineralization Intersected West of Beaver Pond

In a continued effort to explore for new gold mineralization, a total of four drill holes were completed in late 2009 west of the Beaver Pond Zone. The Company is very pleased to report that NR09-413 intersected a new high-grade gold occurrence of 22.2 g/t (0.65 oz/t) gold over 1.5 metres hosted within a wider interval grading 2.10 g/t over 19.5 metres. This newly discovered gold mineralization occurs 300 metres west of the Beaver Pond Zone at a vertical depth of 190 metres below surface and is entirely open down plunge and dip. Two other holes were drilled approx.90 metres along strike to the west and east (NR09-425 and NR09-411, respectively). Anomalous gold was encountered in both holes indicating the system continues to the west. NR09-413 has been incorporated into the upcoming resource update and additional drilling in this new area is currently underway.

Beaver Pond Zone Continues to Display Continuity

NR09-445 intersected two separate gold intervals in the Beaver Pond Zone grading 1.49 g/t gold over 12.0 metres including 3.71 g/t gold over 3.0 metres and 1.07 g/t gold over 12.0 metres at a vertical depth of 200 metres below surface. These twin intervals correlate very well with those intersected approx.55 metres down plunge in NR09-446 (upper interval highlighted by 6.0 metres grading 352.84 g/t gold, see News Release dated January 18, 2010) and at greater depth in previously announced Holes NR09-329 and 402. Additionally, 5.03 g/t gold over 1.5 metres was intersected in the footwall to the Beaver Pond Zone at a vertical depth of 404 metres and represents a new gold occurrence in this formerly untested area. Three rigs are actively drilling at the Beaver Pond Zone.

High Tenor Silver in Beaver Pond Area - Final Assays Received for NR09-446

Final silver assays for the 6.0 metre high-grade gold intersection in previously reported drill hole NR09-446 have been received by the Company. The high grade gold zone in NR09-446 (6.0 metres grading 352.84 g/t gold) contained high silver values grading 114.25 g/t over 6.0 metres. Please see Table 2, Summary of Silver Intercepts, below.

Rainy River is currently assessing the potential silver by product value. The area west of the ODM17 Zone appears to have a higher silver content and modeling efforts are underway to determine the values.

South Zone Drilling Continues to Extend Gold Mineralization Down Plunge

The significant size and continuity of the South Zone continues to be demonstrated with drill hole NR09-442 which intersected a wide interval grading 0.60 g/t gold over a core length of 39.0 metres including 7.5 metres grading 1.47 g/t gold at a vertical depth of 320 metres below surface. NR09-442 is to date the westernmost drill hole in the South Zone and has extended the strike length of the zone to approximately 700 metres. The South Zone remains open not only along strike to the west but also down plunge and down dip. NR09-442 has been incorporated into the pending NI 43-101 resource estimate.

Infill Drilling Expands Mineralization Near Surface in ODM17 Zone and Underlying HS Zone

Four infill drill holes were completed in the near-surface portion of the of the ODM17 Zone at its eastern end to further confirm the inferred-category gold mineralization from the 2009 NI 43-101 resource estimate completed by SRK Consulting Ltd. The holes successfully confirmed the known inferred gold mineralization, and new mineralization was discovered in the footwall area of the ODM17 Zone as well as in the HS Zone which lies between the ODM17 and 433 Zones.

Additional Reverse Circulation Drilling Extends Near-Surface Zones and Defines New Targets

Twenty-eight (28) reverse circulation ("RC") holes were drilled to guide our exploration drilling. Drill hole RC209 intersected 1.5 metres of 6.17 g/t gold at the bedrock-glacial till overburden interface, north of the ODM17 Zone. This opens a new area for detailed exploration.

Drill hole RC-316, 400 metres west of the Beaver Pond Zone contained one of the strongest gold grain-in-till anomalies on the Rainy River Property. This anomaly may be a down ice reflection of the high grade gold intersected in drill hole NR09-413 (see above).

RC drilling is continuing to define and open new exploration targets in the altered caldera rocks that host all of the mineralization discovered to date.

Comments

"Our exploration and delineation drilling continues to discover new targets both along strike and down plunge from existing zones," commented Raymond Threlkeld, President and CEO. "We are aggressively drilling the new areas with six drill rigs. Engineering, metallurgical and resource studies are currently on schedule and we anticipate a new 43-101 resource report in Q1, 2010."

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$19 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.
