Rimfire Minerals Corporation: Tide Drilling Completed

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 26, 2007) - David Caulfield, President and CEO of Rimfire Minerals Corporation ("Rimfire") (TSX VENTURE:RFM) reports that the 2007 drilling program at the Tide Property has been completed. This program consisted of diamond drilling at the 36 Zone and nearby North Pit and Riptide zones, surface channel sampling, and detailed geological mapping. The 2007 program was funded by American Creek Resources Ltd., under an option agreement to earn a 60% interest in the Tide Property.

Eight diamond drill holes, totalling 1835 metres, were completed during the program. Five holes were drilled to test the 36 Zone, where a 2004 discovery drill hole intersected 1.0 g/t gold over 129 metres. One hole was drilled at each of the North Pit and Riptide Zones, as well as one to investigate the area between the two zones. A plan map of the diamond drill hole locations can be found at Rimfire's website (http://www.rimfire.bc.ca/s/Tide.asp).

Crews completed 318 metres of surface channel sampling (121 samples) and detailed geological mapping on selected drill sections and between drill holes to sample east-west trending quartz-pyrite-arsenopyrite mineralized fractures that are the dominant gold-bearing host. Similar, although less extensive sampling in 2006 showed a correlation between fracture density and gold grades. The additional data collected this year will better define spatial trends of higher fracture density to be used for drill targeting in 2008. Analytical results from drilling and surface work are expected by January.

The results contained in this news release have been reviewed by Mark Baknes, M.Sc., P.Geo., Vice President Exploration, a Qualified Person under National Instrument 43-101.
