October 6, 2009 Rainy River Announces Results From Ten New Drill Holes Adds Fifth Drill Rig to Accelerate Testing of Caldera Exploration Targets VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 6, 2009) - Rainy River Resources Ltd. (TSX VENTURE:RR) - Highlights: - 3.0 metres grading 36.85 g/t gold and 15.6 metres grading 6.46 g/t gold intersected in ODM17 Zone - ODM17 Zone extended 100 metres east from previous cutoff - Fifth diamond drill added to test exploration targets - RC drilling planned to develop pipeline of additional gold targets Rainy River Resources Ltd. is pleased to announce the results of the ten most recently completed diamond drill holes on its Richardson Township property in the southwest corner of northern Ontario. All of the holes were drilled within the 600 hectare mineralized core of the Richardson caldera A recently completed NI43-101 resource study (SRK, July 2009; available at www.sedar.com) of the known gold zones in this area estimated 2.2 million ounces of indicated gold resources and 1.8 million ounces of inferred resources, mainly in the ODM17 and 433 Zones. The nine new drill holes were variously designed to: 1) tighten the hole spacing in parts of the ODM17 Zone as required to convert inferred resources to indicated resources; 2) delineate the eastern and western ends of this zone; and 3) explore for new gold zones beyond the known resources. All significant drill results and a location map with section lines for reference are posted on the Rainy River website www.RainyRiverResources.com. The summary tables on pages 3 and 4 of this release are to be read in conjunction with the text, below. Infill Drilling, ODM17 Zone Four infill holes were drilled on the ODM17 Zone. These holes generally intersected more than 30 metres grading 1 to 2 g/t gold, typical of the indicated open pit resources. Much higher grade intersections of 3.0 metres at 36.85 g/t and 15.0 metres at 6.46 g/t were obtained from Holes 376 and 382, respectively. Hole 382 also obtained a near-surface intersection of 5.0 metres grading 1.17 g/t from the overlying Cap Zone. Delimitation Drilling, ODM17 Zone Five holes were drilled at the eastern and western extremities of the ODM17 Zone to better define its limits. These holes generally intersected marginal mineralization as expected although Holes 378, 381 and 384 extended the zone more than 100 metres eastward, returning 22.5 metres grading 0.83 g/t, 15.0 metres grading 0.82 g/t and 16.5 metres grading 0.76 g/t, respectively, all within the limits of the conceptual open pit, thus potentially increasing the resources within the conceptual pit. Exploration Drilling Hole 373 extended the down-plunge mineralization of the recently discovered South Zone, returning 15.7 metres grading 0.70 g/t gold. New Developments A fifth diamond drill rig will be added in mid-October to accelerate testing of newly accessible exploration targets. In addition, a reverse circulation drilling program is planned for November to develop a pipeline of new targets within the 600 ha caldera gold anomaly. Geological Setting The core of the Richardson caldera is infused with gold at an average grade close to 0.1 g/t over a 600 hectare (6 km2) area. This gold was introduced by hot circulating fluids related to the explosive volcanism that produced the caldera basin and filled it with permeable sediments. Higher grade mineralization such as the ODM17 and 433 Zones was concentrated below the least permeable sediment layers. The potential for discovering more gold zones both near surface and at depth is very high. Qualified persons Rainy River's exploration program in Richardson Township is being supervised by Stuart Averill, P.Geo. Vice-President Exploration and is being managed by Wally Rayner, P.Geo., Project Manager, both Qualified Persons as defined by National Instrument 43-101. The Company's regional exploration manager, C.J. Baker, M.Sc., is managing the Company's Off Lake exploration program 15 km to the northeast. Nelson W. Baker, P.Eng. is the Qualified Person for the project and Raymond Threlkeld and Stuart Averill are the persons responsible for the contents 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. The procedures of the QA/QC program are detailed on Rainy River's website at www.rainyriverresources.com. 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 CAN$18 million in its treasury, 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 centered 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. 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.
