Rainy River Drilling Update: 17 Zone Remains Consistent, Third Deep Drill Added

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 12, 2006) - Nelson W. Baker, President of Rainy River Resources Ltd. (TSX VENTURE:RR), reports that two drill rigs continue to focus on defining a NI43-101 gold resource for the 17 Zone on the Company's 100%-owned property centered in Richardson Township approximately 80 kilometers south of Kenora, Ontario. Results have now been received for an additional six (6) holes: NR06-48 and NR06-61 drilled into the 17 Zone, NR06-30 and NR06-35 are located along the 17 Zone gold horizon between the Beaver Pond Zone and the 17 Zone and NR06-34 and NR06-36 tested the western extension of the 433 Zone, approximately 500 metres north of the 17 Zone. Hole NR06-48 intersected the 17 Zone 75 metres west of NR06-28 (15 metres grading 11.57 g/t Au) at the -150m level, extending the strike length of the strong core mineralization to 330m, open to the east and west. Drill holes NR06-30 and NR06-35 are 225 metres and 400 metres further west respectively, along the 17 Zone gold trend. Table 1 summarizes the main intervals intersected in the six holes and Table 2 provides a list of all of the main intersections recorded by Rainy to date into the 17 Zone.

Highlights:

17 Zone:

- NR06-48 intersects 1.5 metres grading 10.05 g/t Au

- NR06-61 intersects multiple intervals: 1.0 metres grading 14.0 g/t Au, 4.1 metres grading 4.25 g/t Au, 1.5 metres grading 3.97 g/t Au

17 Gold Trend (between Beaver Pond and 17 Zone):

- NR06-35 intersects 3.0 metres grading 4.26 g/t Au

- NR06-30 intersects 1.5 metres grading 3.08 g/t Au

433 Zone (500m north of 17 Zone):

- NR06-34 intersects 3.0 metres grading 3.51 g/t Au

- NR06-36 intersects 2.2 metres grading 5.68 g/t Au

Nelson Baker stated that, "Our studies have found that, although relatively close together, the 433 Zone sulphide mineralization and alteration features such as chlorite and biotite distinguish it from the 17 Zone deposit. In fact, we believe that the 433 Zone may represent the "feeder" for the 17 Zone and the Beaver Pond zones. We are anxious to test that theory with the deep drill scheduled to begin this week."

Quality Control

Rainy River has implemented a quality control program to ensure best practice in sampling and analysis of the drill core. The procedures of the QA/QC program were detailed in Rainy's news release of March 13, 2006. Assays equal to or greater than 10 g/t Au were calculated gravimetrically. Assays greater than 100 g/t Au were re-analyzed by fire assign using 50-grams of sample and measured gravimetrically.
