Rainy River Project Drilling Update: #17 Gold Zone Demonstrates Strong Continuity Deep Hole Intersects Zone 500 Metres Downplunge 1.71 g/t Au Over 42.5 Metres

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 11, 2006) - Nelson W. Baker, President of Rainy River Resources Ltd. (TSX VENTURE:RR) ("Rainy") is pleased to report that two deep holes, NR06-25 and NR06-26, designed to test the Company's down plunge theory have been successful in tracing the #17 Zone gold bearing mineralization a remarkable 450 metres below surface and approximately 260 metres from NR06-22 which intersected 11.57 g/t Au over 15.0 metres. In fact, hole NR06-26, the deepest hole drilled to date in the #17 Zone, intersected a wide interval of pyroclastic flow rocks that graded 1.71 g/t Au over 42.5 metres. This mineralized unit is considered to be the down plunge extension of NR06-22. A total of thirty two (32) holes, all of which have intersected the mineralized pyroclastic flow unit, have been completed since January 24, 2006 and drilling continues on the Company's promising Rainy River Project located approximately 80 kilometres south of Kenora, Ontario.

Of the thirty two holes, twenty (20), including NR06-25 and NR06-26, have tested the down plunge gold mineralization in the #17 Zone. This release covers the final results received for five (5) holes from the #17 Zone.

Detailed intervals for all five holes are listed in Table 1.

Highlights:

- NR06-26, a 660 m hole designed to intersect the #17 Zone below the 450 metre level was successful in cutting 1.71 g/t Au over a 42.5 m true width interval

- All five (5) holes in the #17 Zone, NR06-23, NR06-24, NR06-25, NR06-26 and NR06-28 intersected significant gold values across wide intervals

- Two drill rigs are now focused on #17 Zone and a third rig for deep holes is being planned

Drilling Sequence:

From January 24th through to February 21, 2006 a total of ten (10) holes were drilled initially to test the down plunge extension of the #17 Zone (the first five (5) holes were reported on March 13, 2006). After the completion of these holes and prior to receiving any analytical results, a drill rig was moved to test the new Beaver Pond discovery (NR06-09 intersected 5.98 g/t Au over 8.50 metres) and a second to test both a new gold target 100 metres north of the 433 Zone and a "gold in till" anomaly generated on the newly-acquired Shwedack Property approximately 1 kilometre north of the 433 Zone. After receiving impressive results in holes NR06-19, NR06-20 and NR06-22, both rigs were moved back onto the #17 Zone on March 8, 2006 and have now completed an additional ten (10) holes. The drilling is testing a "fence" of holes 30 metres apart at the 200 metre level for a strike distance of over 300 metres. Drill holes NR06-38, NR06-42 to NR06-50 have been sawed and sampled in their entirety and have all been submitted to ALS Chemex Laboratory in North Vancouver for processing. Due to the high volume of sampling for this project and the overall high level of gold exploration in the industry, Rainy has experienced abnormal delays in receiving assay results. A location plan of all holes drilled to date will be posted on Rainy's website www.rainyriverresources.com shortly.

#17 Gold Zone Update

Mineralization in the #17 Zone occurs in the lower part of a pyroclastic flow deposit and in the upper part of a felsic conglomerate that hosts up to 15% sulphides consisting of pyrite, sphalerite (Zn), galena (Pb), minor chalcopyrite (Cu) and native gold. Based on recent drilling successes, Rainy has now established that, although the #17 Zone host rocks strike about 115 degrees and dip 50 to 70 degrees to the south, the gold-dominant mineralization plunges 60 to 70 degrees to the southwest. A recently completed 660 metre hole, NR06-26, the deepest hole drilled to test Rainy's theory, proved highly successful in establishing strong continuity to the 450 metre level representing a 500 metre down plunge extension of the zone. NR06-26 intersected an impressive true width interval of 1.71 g/t Au over 42.5 metres. Within this interval is a higher grade section of 7.5 metres grading 2.90 g/t Au. This mineralized pyroclastic flow unit is interpreted to be the southwest down plunge extension (280 metres) from NR06-22 which intersected 11.57 g/t Au over 15.0 metres (see March 13, 2006 release).

A second 610 metre hole, NR06-25, located 600 metres east of NR06-26 and near the eastern limits of the #17 Zone, was also successful in intersecting 5.20 g/t Au over a 2.0 metre interval at a vertical depth of about 425 metres. Although this intersection is over a narrow interval, it further demonstrates continuity of the gold mineralization to depth. Three shorter holes, NR06-23, NR06-28 and NR06-28 pierced the down plunge gold zone above NR06-22 and NR06-20 respectively at the 150 m level. The final results for all five (5) holes are listed in Table 1 appended to this release.
