      Rimfire Completes Drilling at The Walmer Property, Australia
=======================================================================

PR08--16

Vancouver, BC -- November 12, 2008:  Rimfire Minerals Corporation,
TSX-V:RFM, announces that drilling has been completed at the Trounce
gold prospect on the Walmer Property, Australia. The Walmer Property is
located 40 km south of Dubbo, in New South Wales. Drilling consisted of
four diamond drill holes for a total depth of 286 metres. Assays are
pending.

Drilling targeted the Trounce gold prospect, a subtle, north-south
striking topographic high, coincident with anomalous gold soil
geochemistry and a 40 metre-wide by 500 metre long chargeability and
resistivity high. This topographic and geophysical signature is open to
the north and south and is coincident with the trace of a
regional-scale thrust fault. Two of seven grab samples from the showing
returned gold values of 2.4 and 3.6 g/t gold from silicified sediments
with quartz -- pyrite veining and stockwork and the remaining five
assayed from 0.21 to 0.61 g/t gold. Float samples of similar material
sampled directly adjacent to these outcrops returned highlight values
of 3.5, 5.9 and 7.4 g/t gold. The Trounce showing is marked by
historical workings, but has had no modern exploration. Surface rock
and soil samples with anomalous gold values extend the potential strike
length of the system to at least 750 metres.

The Walmer Property was one of nine properties acquired in 2007 based
on targets identified in a neural network study conducted within a
120,000 square kilometre area of interest in New South Wales. Rimfire
maintains two other properties in New South Wales:
.. The Barmedman property located 50 kilometres south of Barrick Gold
Corp's 5 M oz Cowal epithermal gold deposit. A 2008 Induced
Polarization (IP) survey identified a buried chargeability high anomaly
0.5 by 1.4 kilometres in size. While the source of the IP anomaly is
not exposed at  Barmedman, copper and gold mineralization has been
identified over large widths in recent drilling on adjacent properties
operated by other junior explorers such as Goldminco.
.. The Springfield property lies 12 kilometres south-southeast of the
historic mining town of Gulgong and 80 kilometres northeast of the
Cadia Valley copper-gold porphyry mining complex. A regional scale
Induced Polarization (IP) survey has been completed and results are
currently being analyzed.

This news release has been reviewed by Mark Baknes, M.Sc., P.Geo., VP
Exploration for Rimfire Minerals Corporation, a Qualified Person for
the purpose of National Instrument 43-101.

Director Resigns
David Caulfield, Chairman of the Board of Directors regretfully accepts
the resignation of Mr. Ian Talbot from the company's Board of
Directors.  Mr. Talbot served as a director since January, 2007 and
prior to that was the Company's Corporate Secretary. Mr. Talbot's
resignation comes as a result of recently accepting the position of
Chief Operating Officer with the Strategic Group of companies. Two
companies within this group employ a similar business strategy to
Rimfire and operate in the same jurisdictions. All parties felt it
appropriate for Ian to resign his seat on the Board to avoid potential
conflicts of interest. Rimfire would like to thank Ian for his
contribution and wishes him well in his new endeavour.

Treasury

Rimfire Minerals Corporation currently has in excess of C$6 million in
working capital. Historically, 80% of Rimfire's exploration exposure is
funded by partners. Given the quality of our exploration partners and
assuming this continues, Rimfire expects similar funding requirements
going forward. This scenario would give Rimfire approximately two to
three years of operating capital based on current exploration plans.
