Rainy River Resources Ltd.: Massive Pyrite Intersection Carries Robust Gold and Silver Values

NR09-322: 2.1 m grading 5.73 g/t Au, 34.61 g/t Ag NR09-320: 52.5 m grading 1.68 g/t Au and 4.6 m grading 5.31 g/t Au NR09-332: 7.2 m grading 7.52 g/t Au and 1.5 m grading 26.66 g/t Au

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 30, 2009) - Rainy River Resources Ltd. (TSX VENTURE:RR) is pleased to report the results for five drill holes recently completed in the Richardson Township gold-bearing caldera complex. Four of the five holes, NR09-320, NR09-332, NR09-334 and NR09-335, are part of in-fill drilling within the 17/ODM, HS and 433 Zone main resource area. NR09-322 is an isolated drill hole located outside of the main resource area 500 m west-northwest of the 433 Zone and 300 m east of NR09-302 reported in a previous press release (January 20, 2009). This step-out hole was designed to test Target 3, a gold-in-bedrock anomaly defined in last year's reverse circulation (RC) drilling program and interpreted to be the western extension of the 433 Gold Trend overlying the broadly auriferous (600 ha) caldera complex in Richardson Township 55 km northwest of Fort Frances, Ontario.

NR09-322 INTERSECTS GOLD-RICH VMS-STYLE MINERALIZATION

The discovery of classic VMS-style mineralization within the gold-bearing Richardson caldera complex is another important event for the Company. NR09-322 intersected a 2.1 m interval consisting of a 30 cm interval of volcanogenic massive pyrite mineralization and a 1.8 m interval of 25% stringer sulphides overlying it. Combined the 2.1 m (6.9 ft) interval graded 5.73 g/t (0.17 opt) Au, 34.61 g/t (1.01 opt) Ag with anomalous, zinc, bismuth and cadmium values. A second interval 150 m below the VMS-style mineralization graded 1.53 g/t Au and 13.04 g/t Ag over a 7.2 m true width section. Right angle foliations observed in the core suggest that both mineralized intervals are close to true width. Details of all intervals are highlighted in Table 1, below.

17/ODM, HS, 433 IN-FILL DRILL RESULTS

Four in-fill drill holes intersecting the main resource area continue to confirm wide intervals of impressive gold mineralization. NR09-320, positioned to intersect all three gold horizons (17/ODM, HS, 433) intersected a wide 52.5 m interval grading 1.68 g/t Au including three distinct, higher grade intervals of 10.5 m grading 2.52 g/t Au, 6.0 m grading 3.67 g/t Au and 4.6 m grading 5.31 g/t Au. A surface plan illustrating these relationships has been posted on the Company's website www.rainyriverresources.com.

Three drill rigs are active in Richardson Township. Two of the three rigs have been dedicated to drill testing Target 1 area following up on the recent new gold discovery reported by the Company in the March 11, 2009 news release (NR09-329) and the third drill is completing the in-fill drilling in the main resource area.

About Rainy River Resources Ltd.

Rainy River Resources is a Canadian precious metals exploration company whose key asset is the Rainy River gold project. With a $26.0 million treasury, the Company is well funded to conduct a dual-focused program consisting of: 1) definition diamond drilling of the main gold resource with accompanying scoping-style studies, and 2) selective diamond drill testing of high-priority gold targets defined primarily by RC drilling within the large gold system centered in Richardson Township. The Company's property is extremely well located in northwestern Ontario near the U.S. border. It is accessed by a network of roads and is close to hydro-electric infrastructure. The Rainy River district has a skilled labour force and is one of the lowest-cost areas for mineral exploration and development. Ontario has low political risk and, according to the annual Fraser Institute global survey of the mining industry, has consistently ranked as one of the top jurisdictions embracing mineral development.
