Rimfire to Commence Quesnel Trough Airborne Geophysical Survey

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 14, 2007) - David Caulfield, President and CEO of Rimfire Minerals Corporation ("Rimfire") (TSX VENTURE:RFM) is pleased to report a crew has been mobilized to start a detailed airborne magnetics survey on recently acquired tenure in the Quesnel Trough region of north-central British Columbia. Rimfire will integrate this data with electromagnetic and gravity data collected through Geoscience BC's $5.75 million QUEST survey to focus exploration for copper-gold deposits in 2008.

To date, Rimfire has acquired seven properties (approximately 330 square kilometres) located south of Prince George to northeast of Fort St. James, BC. This portion of the Quesnel Trough is largely covered by glacial overburden, but is prospective for porphyry copper-gold deposits similar to Mt. Polley, Mt. Milligan, and Serengeti Resources' new Kwanika copper-gold discovery. Other explorers that have acquired large land positions in the region include Xstrata Copper, NovaGold Resources Inc., Fjordland Minerals, Serengeti Resources, Geoinformatics Exploration and Peak Geological.

The survey will be conducted by McPhar Geosurveys Ltd. of Markham, Ontario, flying approximately 2000 line-kilometres on 200 metre line spacings.

2007 Overview

Rimfire has made significant additions to its portfolio of properties in 2007 with exploration conducted on 12 separate projects, including five drilling programs. Pending drilling results include the Wernecke Breccia, Tide, and Goodpaster District projects, while drilling at the Jake Property will start in mid-November. Our joint venture business model also continues to increase shareholder value with $10 million in exploration expenditures this year, 85% of which is funded by our partners.
