Rainy River Resources' Intrepid Zone Continues to Expand, Demonstrating Excellent Gold and Silver Grades and Widths Near Surface

Wednesday, December 05, 2012

Rainy River Resources' Intrepid Zone Continues to Expand, Demonstrating Excellent Gold and Silver Grades and Widths Near Surface06:00 EST Wednesday, December 05, 2012/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/ RR.TSXTORONTO, Dec. 5, 2012 /CNW/ - Rainy River Resources Ltd. ("Rainy River" or the "Company" (RR.TSX)) is pleased to announce further assay results from the Intrepid Zone ("Intrepid") at the Rainy River Gold Project ("RRGP") in northwestern Ontario.  Results are summarized in Table 1.HIGHLIGHTSNear surface, drill hole NR121442 intersected 1.9 grams per tonne ("g/t") gold and 23.4 g/t silver over 57.0 metres, starting at a vertical depth of 72 metres below surface, including 2.5 g/t gold and 27.7 g/t silver over 36.0 metres. Drill hole NR121448, located 20 metres west of NR121442, intersected 1.8 g/t gold and 22.3 g/t silver over 28.5 metres, starting at a vertical depth of 45 metres and at the bedrock / overburden interface. Drill hole NR121446 intersected 2.9 g/t gold and 10.6 g/t silver over 33.0 metres, 25 metres down dip of NR121448 and at a vertical depth of 79 metres. Other results include drill hole NR121424, which intersected 8.4 g/t gold and 72.4 g/t silver over 4.5 metres at a vertical depth of 400 metres. NR121461 intersected 7.5 g/t gold and 23.3 g/t silver over 7.5 metres at a vertical depth of 205 metres.INTREPID - LATEST DRILL HOLE RESULTSTo date, 51 diamond drill holes have intersected the Intrepid Zone over a 335 metre strike length, and have traced the mineralization down dip for 450 metres.Results Suggestive of Potential Open Pit MineralizationEleven of the eighteen drill holes reported in today's Intrepid Zone results show widths suggestive of open pit mining potential, with wide zones of near-surface gold mineralization. Drill hole NR121442 intersected 1.9 grams per tonne ("g/t") gold and 23.4 g/t silver over 57.0 metres, which represents the widest intersection to date. This hole remains open to the east.  Widths and grades are comparable to those of the ODM Zone, with thickness and grade increasing as drills move eastward.Drill hole NR121448 intersected 1.8 g/t gold and 22.3 g/t silver over 28.5 metres, starting at a vertical depth of 45 metres, while NR121446 intersected 2.9 g/t gold and 10.6 g/t silver over 33.0 metres, at a vertical depth of 79 metres. These drill results show significantly larger widths than seen in previous drill results.These holes all lie immediately east of the Intrepid discovery hole NR121258, reported October 22, 2012.Results Suggestive of Potential Underground Mineralization Seven of the eighteen holes reported today were drilled to the west of the wider zones of mineralization. These holes returned significant grades and widths which could potentially become mineable via the planned underground decline, with high-quality ounces brought forward earlier in the underground mine life.  NR121424 intersected8.4 g/t gold and 72.4 g/t silver over 4.5 metres at a vertical depth of 400 metres, and NR121427 intersected 6.0 g/t Au and 7.0 g/t silver over 3.0 metres at a vertical depth of 404 metres.  These two holes are over 100 metres down plunge of Rainy River's previous drill intersections at Intrepid.  Additionally, NR121461 intersected 7.5 g/t gold and 23.3 g/t silver over 7.5 metres at a vertical depth of 205 metres.Maps and Images Note: Map 2 to Map 5 are cross sections moving progressively to the east.Map 1 - Diamond Drill Hole Location Plan MapMap 2 - 427310 E Cross SectionMap 3 - 427460 E Cross SectionMap 4 - 427489 E Cross SectionMap 5 - 427512 E Cross SectionMap 6 - Vertical Longitudinal SectionCOMMENTARYRaymond Threlkeld, President and CEO of Rainy River Resources Ltd., commented: "Today's results include some of the best intersections we have seen to date at the Intrepid Zone, providing further support for the open pit potential of this exciting new discovery, in addition to the potential contribution of high-quality ounces early in the underground mine life.  Located one kilometre away from the main Rainy River Gold Project, and with 51 drill holes completed, Intrepid now has a 335-metre strike length and measures 450 metres down dip. The Intrepid Zone continues to expand eastward, widening as it nears the surface, and demonstrating very good potential for the Rainy River Gold Project. As we move into the development stage with our namesake project, we remain committed to realizing more of the exploration upside in the Rainy River gold district."Qualified personsRainy 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.  Mr. Sparkes, P.Geo. is also the person responsible for the content of this news release. The Company has a rigorous QA/QC program in place 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 1000 g 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 RiverRainy River Resources Ltd. is a Canadian precious metals exploration company whose key asset is the Rainy River Gold Project, a large gold system centred in Richardson Township (part of Chapple Township). As of September 30, 2012, the Company had approximately $62 million in cash and cash equivalents and short-term investments, and remains well funded for its 2012 plans to 1) commence a feasibility level study on the RRGP; 2) continue growing the existing resource through exploration; 3) conduct a condemnation program in areas identified for potential mine facilities; and 4) continue regional exploration. RRGP is very 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 in Canada. 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.RAINY RIVER RESOURCES LTD.Raymond W.
