RAINY RIVER RESOURCES INTERSECTS 1,335.0 G/T GOLD & 76.7 G/T SILVER OVER 1.5 METRES NEAR SURFACE IN WESTERN AREA

Rainy River Resources Ltd. has released its assay results from the Rainy River gold project in Northwestern Ontario where the company is completing 170,000 metres of diamond drilling in 2011. Results are summarized in the table.

Highlights:

• Western area continues to expand with high-grade gold and silver;

• NR11719 intersects 1,335.0 grams per tonne gold and 76.7 g/t silver over 1.5 metres located 42 metres below surface;

• NR11711 intersects 4.4 g/t gold over 10.5 metres and NR11731 intersects 3.9 g/t gold over 22.5 metres;

• Infill program returns 1.2 g/t gold and 1.8 g/t silver over 93 metres in ODM zone.

Western area

The Western area is a new exploration target located approximately 800 metres northwest of the Beaver Pond (BP) zone, lying within a large magnetic low trend that hosts the Rainy River gold deposit and stretches over 10 kilometres to the west. Drilling has continued on this zone since the first significant gold intersection was reported in the March 30, 2011, press release, where hole NR11648 intersected 7.1 g/t gold and 23.0 g/t silver over 9.0 metres.

Eleven new shallow holes are reported in this release. The three most prominent holes include NR11719, which intersected 1,335.0 g/t gold and 76.7 g/t silver over 1.5 metres directly at the overburden-bedrock contact, located 42 metres below surface. In addition, hole NR11711 intersected 4.4 g/t gold and 1.2 g/t silver over 10.5 metres, and hole NR11731 intersected 3.9 g/t gold and 9.8 g/t silver over 22.5 metres. Significant gold mineralization has been intersected at relatively shallow depths, with results beginning to demonstrate the potential for continuity that may eventually develop into a new near-surface mineralized zone. Drilling will continue to expand this mineralization to the south and also toward the main resource pit.

Infill program

The first results from the infill program returned wide intersections of continuous gold mineralization. This program is primarily designed to upgrade inferred resources into the measured and indicated categories for incorporation into a future feasibility study. Drill hole KCBL101, originally drilled for geotechnical purposes, has now been assayed and has returned 1.2 g/t gold and 1.8 g/t silver over 93 metres in the heart of the ODM zone from 230 to 323 metres down hole including 4.1 g/t gold and 3.0 g/t silver over 9.0 metres from 248 m to 257 m down hole. NR11718 returned values of 1.8 g/t gold over 39 metres, including 4.2 g/t gold over 13.0 metres in the 17 East zone, while NR11729 returned values of 1.0 g/t gold over 11.0 metres, and NR11724 returned values of 16.5 g/t gold and 16.9 g/t silver over 1.5 metres. Six rigs are currently on site for infill drilling.

District exploration

The company's district exploration program is continuing, with one drill rig following up on gold-in-till anomalies identified from past reverse circulation drill programs, and a second drill rig is completing a north-south fence of stratigraphic holes through the property for geological purposes. Exploration drilling north of the main deposit area continues to return encouraging results, including drill hole NR11692 with 7.9 g/t gold reported over 1.5 metres, drill hole NR11693 with 34.2 g/t gold over 1.5 metres and drill hole NR11694 which intersected 5.3 g/t gold over 1.5 metres.

Commentary

Raymond Threlkeld, president and chief executive officer, adds: "These results are very encouraging and confirm our belief that the Western area has the potential to add resources to the project. Grades and widths appear to be increasing as we explore towards the Beaver Pond zone, and the company will be conducting further drilling in this area over the next few months. Early results from our district exploration program have identified several narrow, high-grade intercepts which represent excellent target areas for further exploration."

Qualified persons

Rainy River's exploration program in Richardson township is being supervised by Kerry Sparkes, PGeo, vice-president exploration, a qualified person as defined by National Instrument 43-101. Garett Macdonald, PEng, vice-president operations, and Mr. Sparkes are the persons responsible for the content of this news release. The company continues to implement a rigorous quality assurance/quality control program to ensure best practices in sampling and analysis of drill core. All drill core is marked for sampling and then split in half with a diamond saw blade. Samples are placed in sealed bags with security tags. All samples were assayed using a standard fire assay, 30-gram nominal sample weight with an AA finish. Overlimit samples were reassayed with a gravimetric finish. Samples with visible gold were automatically analyzed for ore grade by 1,000-gram screen fire assay, with coarse and fine fractions being combined proportionately and the fine fraction being assayed twice. Standards, blanks and duplicates are inserted every 25 metres. ALS Canada Ltd. performed primary assaying, with duplicates being analyzed at Activation Laboratories Ltd. ALS Canada Ltd. and Activation Laboratories Ltd. implement independent QA/QC protocols that include the insertion of certified blanks and standards as part of their routine analysis.
