Robust Gold Intersection Recorded on the Bayfield "Burns Block", Another New Gold Zone Emerging Along Rainy River's 17 Gold Trend, NR08-283 Intersects 4.5 Metres Grading 7.34 g/t Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 16, 2008) - Nelson W. Baker, President and CEO of Rainy River Resources Ltd. (TSX VENTURE:RR), is pleased to report that another new gold zone is emerging along the 3.5 km long 17 Gold Trend. This trend, which has been systematically explored for a 1.6 km strike length, hosts the Beaver Pond, ODM and 17 Zones and now the 17 East Zone. Similar to the new discovery announced in the Company's September 9th, 2008 release, the 17 East Zone lies in an area of thin overburden and extensive bedrock outcrops outside the previously interpreted eastern margin of the main caldera anomaly, one of Canada's largest gold footprints. The first indications of the 17 East Zone were obtained late last year in hole NR07-189 (news release dated October 15, 2007) but the zone was not pursued at that time because the surface outcrops are not anomalous in gold. The newest intersection, in Hole NR08-283, extends the zone further east onto the "Burns Block", 100%-owned by Bayfield Ventures Corp. (TSX VENTURE:BYV). Under an option agreement, Rainy River has the right to earn a 60% interest in the Burns Block property over a 3-year period by incurring $1 million in exploration expenditures in each year during the term of the option (news release dated December 3, 2007).

Hole NR08-283, a 42 m step-out east of NR08-258 (news release July 29, 2008), was collared near the eastern boundary of Rainy River's property but deviated eastward where, approximately 30 metres inside the "Burns Block" at the -420 m level, it intersected a 4.5 m interval grading 7.34 g/t Au. Hole NR08-258 intersected 10.5 m grading 2.83 g/t Au and NR07-189, approximately 150 m further west, intersected 9.0 m grading 6.64 g/t Au. The strike length of the 17 East Zone is now 190 metres and the zone remains open in all directions. The details of the mineralized intervals for holes NR08-283, NR08-258 and NR08-189 are highlighted in Table I below and the hole locations will be posted on the Company's website www.rainyriverresources.com.

Two of the four rigs actively drilling within the large gold footprint have now been mobilized to the Burns Block. One will be dedicated to the northern part of the property and the second rig, which is capable of drilling greater than 1000-metre holes, will continue to define the 17 East Zone both up-plunge and along strike.

Nelson Baker remarked: "This marks the second important new gold discovery for Rainy in the space of a few weeks. Both occur in an area that was previously thought to be outside of the large gold footprint. This is truly an unusual gold project with so much upside potential for additional discoveries."
