Rainy Continues to Intersect Strong Gold Values in ODM and 17 Zone Drilling: 30.0 Metres Grading 2.04 g/t Gold, 10.0 Metres Grading 2.73 g/t Gold and 6.0 Metres Grading 5.98 g/t Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 11, 2007) - Nelson W. Baker, President and CEO of Rainy River Resources Ltd. (TSX VENTURE:RR), is pleased to provide the results for six additional holes (NR07-174, 175, 177, 178, 179 and 180) drilled into the ODM and the 17 gold zones situated in Richardson Township on the Company's 100%-owned Rainy River Project 80 kilometres south of Kenora, Ontario. It is important to note that all six holes were completed between June 6th and July 23rd, 2007. Due to the high level of drilling activity in northwestern Ontario, it has taken up to 90 days to receive the final analytical results from the lab. Three of the above holes, NR07-174, 175 and 177, were designed to trace the down plunge extension of the ODM Zone, while NR07-179 tested the near surface, western extension of this zone. Holes NR07-178 and NR07-180 intersected the down plunge extension of the 17 Zone below the 300 metre level.

HIGHLIGHTS

- NR07-174 intersects a 12.0-metre interval grading 1.54 g/t gold 50 m east of NR07-156.

- NR07-179 intersects a 10.0-metre true width interval grading 2.73 g/t gold in the upper western part of the ODM Zone within a 26.0-metre interval grading 1.62 g/t gold.

- NR07-180 intersects a 6.0-metre true width interval grading 5.98 g/t gold in the central part of the 17 Zone at the 400 metre level within a 30.0-metre interval grading 2.04 g/t gold.

- A recently completed reverse circulation till and bedrock sampling program straddling the 17 Gold Trend west of the Beaver Pond Zone has highlighted two new high priority gold targets.

The details of all intervals for the six diamond drill holes are highlighted in Table 1, below and separate location plans for the six diamond drill holes and the 34 recently completed RC holes will be posted on the Company's website www.rainyriverresources.com later this week.

During May 2007, the Company completed a 34-hole reverse circulation ("RC") basal till and bedrock gold sampling program under the supervision of Overburden Drilling Management Limited. This RC program was designed to generate other potential "hidden" gold targets that remained untested within the large 6 sq. km "gold in till" anomaly. This program was successful in defining two new sub-cropping gold zones that have not been previously drill tested.

As indicated in the Company's previous release (August 28, 2007), three drill rigs continue to focus on the 17 and ODM zones. A fourth drill rig, capable of 2500-metre holes, is expected to mobilize to the property shortly and a fifth rig is planned for early October. Presently, ten holes, all drilled in the ODM and 17 Zones, have been completed, sampled and submitted to the lab for analysis.
