Rainy River's ODM Zone Continues to Record Wide Intervals of Impressive Gold Values and Remains Open Along Strike and Down Plunge

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 15, 2007) - Nelson W. Baker, President of Rainy River Resources Ltd. (TSX VENTURE:RR) is pleased to report the results for seven additional drill holes recently completed in the ODM Zone which is located between the Company's Beaver Pond and 17 Zones. The Company has drilled a total of nineteen holes, including the seven holes reported on in this release, testing the ODM Zone from surface to the -300m level and for approximately 100 metres of strike length. Table II summarizes the results of the first fifteen holes released. Table I summarizes the gold intervals for the new holes NR06-138, NR06-139, NR06-140, NR06-141, NR06-142, NR06-143 and NR06-144. Detailed intervals will be posted on our website www.rainyriverresources.com shortly.

Hole NR06-138, the deepest hole down plunge to date (-300m) was successful in intersecting a 4.5 metre interval grading 22.64 g/t Au (uncut). Equally impressive was the intersection in NR06-143 consisting of 6.0 metres grading 8.65 g/t Au within a wider interval of 25.0 metres grading 2.67 g/t Au. This intersection is approximately 30 metres up plunge from the NR06-111 which cut 23.5 metres grading 10.63 g/t Au. The weighted average for all fifteen holes in Table II is 4.65 g/t Au with an average true thickness of 24.11 metres.

The Company's principal focus continues to be to drill test the 3 kilometre 17 Gold Trend at 60-metre centers between the ODM Zone and the West Zone, a distance of about 1.8 kilometers using the three drill rigs that are on site. Other high priority gold targets to be drilled will be the eastern extension of the 17 Zone and in the 433 Zone area.

The Company's 100%-owned Rainy River Project is located 80 kilometres south of Kenora, Ontario, a region of low political risk, low exploration costs and excellent infrastructure. The Company has implemented QA/QC (quality assurance/quality control) procedures for the Rainy River project. These QA/QC procedures have been described in detail in a news release dated December 4, 2006.

Mr. Baker, PEng., is the qualified person for the Rainy River Project and the person responsible for the contents for this release.

Nelson W. Baker, President
