Rainy River Resources Expands Western Area With 15.9 g/t gold and 41.1 g/t Silver Over 4.5 Metres

TORONTO, ONTARIO--(Marketwire - July 13, 2011) - Rainy River Resources Ltd. (TSX VENTURE:RR) (the "Company" or "Rainy") is pleased to announce assay results from the Rainy River Gold Project (RRGP) in northwest Ontario where the Company is completing 170,000 m of diamond drilling in 2011. Results are summarized in Table 1.

Highlights

  • Western Area expands with drill hole NR11750 intersecting 7.6 g/t gold and 26.5 g/t silver over 16.5 m, including 15.9 g/t gold and 41.1 g/t silver over 4.5 m.

  • In addition, zone continuity is improving at 17 East Extension with NR11735 returning 6.9 g/t gold and 112.3 g/t silver over 7.0 m and NR11737 returning 29.4 g/t gold and 124 g/t silver over 1.7 m, at a vertical depth of 554 m.

Western Area

Follow up drilling to hole NR11731, which intersected 3.9 g/t gold and 9.8 g/t silver over 22.5 m (news release dated July 6, 2011) continues to intersect significant gold mineralization. Approximately 50 m down plunge of NR11731, NR11750 intersected 7.6 g/t gold and 26.5 g/t silver over 16.5 m, including 15.9 g/t gold and 41.1 g/t silver over 4.5 m, confirming the presence of southwest plunging high grade shoots that are characteristic of the RRGP. This intersection is located at a vertical depth of 86 m below surface.

These two intersections are open both up and down plunge, and represent the most easterly holes that would intersect the mineralized trend connecting the Western Area to the main RRGP resource, located approximately 800 m to the southeast of the Western Area.

17 East Extension Zone

Deep exploration on the 17 East Extension Zone continues to intersect encouraging gold and silver results while demonstrating improved continuity. This zone lies on the east side of the ODM-17 ore body and at a vertical depth approximately between 500 - 750 m. Drill hole NR11735 intersected a 31.5 m wide interval grading 2.7 g/t gold and 31.1 g/t silver, including 6.9 g/t gold and 112.3 g/t silver over 7.0 m. Within this interval was a 1.0 m wide intersection of mineralization grading 30.1 g/t gold and 688.0 g/t silver.

Also in the 17 East Extension, assays from drill hole NR11737 returned 12.2 g/t gold and 61.7 g/t silver over 4.5 m including 29.4 g/t gold and 124.0 g/t silver over 1.7 m at a vertical depth of 554 m. This intersection is 60 m up dip from NR10621E, which reported 13.9 g/t gold and 353.3 g/t silver over 4.5 m (news release dated May 16, 2011).

Additional assay results from the 17 East Extension include NR11726, which intersected 4.0 g/t gold and 4.0 g/t silver over 3.0 m at a vertical depth of 608 m, and a second intersection at a vertical depth of 628 m grading 2.6 g/t gold and 133.3 g/t silver over 3.0 m. This intersection lies 50 m up dip of previously reported drill hole NR10627E which returned values of 69.7 g/t gold and 17.7 g/t silver over 1.5 m (news releases dated May 16, 2011). At 50 m down dip of NR11676 (2.5 g/t gold and 19.3 g/t silver over 9.0 m, reported on May 16, 2011), drill hole NR11695 intersected 3.0 m grading 3.9 g/t gold and 19.3 g/t silver at a vertical depth of 599 m.

The 17 East Extension continues to expand westwards with NR11705 returning values of 3.7 g/t Au and 7.9 g/t silver over 6.0 m at a vertical depth of 595 m, and NR11691, which is located 50 m down dip of NR11705, returning values of 1.1 g/t gold and 17.8 g/t silver over 19.1 m. These holes lie approximately 70 m to the west of the most recent drilling in the 17 East Extension zone.

The 17 East Extension continues to demonstrate high grade gold and silver mineralized shoots within a broad, continuous, well-mineralized envelope. Drilling will continue to selectively target higher grade shoots within the 17 East Extension over the remainder of the year.

Commentary

Raymond Threlkeld, President and CEO, adds "Exploration continues on the Western Area and 17 East Extension zones, two exciting new areas which may represent extensions of the main Rainy River gold deposit. Grades and widths are very encouraging, with NR11750's intersection in the Western Area being one of the best on the project to date. We will continue to explore these prospective new areas and complete infill drilling within the main deposit area to prepare for feasibility."

Qualified persons

Rainy River's exploration program in Richardson Township is being supervised by Kerry Sparkes, P.Geo., Vice-President Exploration, a Qualified Person as defined by National Instrument 43-101. Garett Macdonald, P.Eng., Vice President Operations and Kerry Sparkes, P.Geo. are the persons responsible for the content of this news release. The Company continues to implement a rigorous QA/QC 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. Over-limit samples were re-assayed with a gravimetric finish. Samples with visible gold were automatically analyzed for Ore Grade by 1000g 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. implements independent QA/QC protocols that include the insertion of certified blanks and standards as part of their routine analysis.

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 approximately $120 million in cash and short term investments, the Company is well funded to conduct a dual-focused drilling program consisting of: 1) definition diamond drilling of the main gold resources in preparation for scoping and pre-feasibility studies, and 2) selective diamond drill testing of high-priority gold targets defined primarily by RC drilling within the large gold system centred in Richardson Township. The Company's property is extremely well located in the southwestern corner of northern 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. The Company is also working to advance the early-stage discoveries at its TPK Joint Venture Property, also in Ontario, where it can earn a 51% interest in the property from Northern Superior Resources Inc. 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.
