Rainy's Deepest Hole (NR07-198) Intersects 12 Separate Gold Intervals

Principal Gold Trends Predictable at Great Depths

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 19, 2008) - Nelson W. Baker, President and CEO of Rainy River Resources Ltd. (TSX VENTURE:RR), is pleased to report that assays have now been received for the entire drill hole NR07-198, the deepest hole drilled by the Company to date. As reported previously in the Company's November 5, 2007 news release, a 4.0 m section in the upper part of the hole, from 494.5 to 498.5 m, returned 25.67 g/t gold and 184.14 g/t silver. This intersection was from the Cap Zone of the Cap Gold Trend, the most southerly of the three principal sheet-like, stratigraphically controlled gold trends that are being drill tested. Hole 198 was continued northward to test the stratigraphically underlying 17/ODM and 433 Gold Trends at a much greater depth than previous holes. Its total depth was 1656 metres. The details of all intervals for this hole are highlighted in Table 1 below.

Eleven additional gold intercepts were obtained including three wide intervals of 27.0 m (from 854.0 to 881.0 m), 7.5 m (from 1011.5 to 1019.0 m) and 44.4 m (from 1131.5 to 1176.5 m) grading 0.5 to 1.0 g/t gold. These three intercepts appear to correlate closely with the 17/ODM Trend, the HS sub-trend and the 433 Trend respectively. Their 0.5 to 1 g/t grades are similar to the grades obtained from shallow holes drilled between the higher-grade, southwest-plunging gold zones that occur intermittently along these gold trends, for example between the East, 17, ODM and Beaver Pond Zones on the 17 Gold Trend. Hole 198 wandered well to the east of its intended path through the main gold zones.

Nelson Baker states, "Importantly, the deep gold intercepts clearly demonstrate that the overall mineralized system and its principal gold trends remain intact and predictable at great depth and indeed they may be as deep as they are long (up to 3 km)."
