      Rimfire Minerals Reports Grizzly Drill Results
=======================================================================

PR09-05

Vancouver, BC -- March 9, 2009:  Rimfire Minerals Corporation,
TSX-V:RFM, reports results from the drill program concluded on the
Grizzly property last fall. The program, totalling 2128 metres in 11
holes, targeted two areas: the Grizzly Showing and the Mirko Grid.
Drilling confirmed the presence of weak porphyry-style copper-gold
mineralization and alteration at the Grizzly Showing and wide intervals
of anomalous molybdenum-bearing mineralization at the Mirko Grid.

The 2008 program was funded by Inmet Mining Corporation under the terms
of an Option agreement announced January 2008.

Eight holes were collared in the Grizzly Showing area targeting Induced
Polarization (IP) chargeability anomalies coincident with
copper-gold-molybdenum soil geochemical anomalies and copper-gold
surface showings. Previously reported mineralization from trenches at
the Grizzly Showing returned results including 38 metres averaging
0.74% copper and 1.1 g/t gold from continuous chip sampling. Three
holes were completed in the immediate vicinity of the showing; one
tested the down-dip extent of the Grizzly Showing (GRIZ08-02) and two
holes were drilled to test the inferred strike extent 100 metres to the
NE and SW of the showing (GRIZ08-11 and -05, respectively). These holes
intersected numerous zones of potassium feldspar+biotite+carbonate
alteration with trace chalcopyrite disseminations and
calcite-chalcopyrite veins in mafic volcanic rocks. Results include
53.73 metres of 0.11% copper and 0.19 g/t gold including 17.38 metres
of 0.21% copper and 0.28 g/t gold in GRZ08-11. Drilling confirms that
this high-temperature, porphyry-style alteration and mineralization is
spatially associated with syenitic feldspar-porphyry dykes and sills.
Two holes drilled 200 metres east-northeast (GRIZ08-01) and 350 metres
northeast (GRZ08-03), that targeted IP chargeabilitiy highs intersected
moderately to strongly chlorite+sericite�carbonate�biotite �potassium
feldspar altered volcanic and intrusive rocks with abundant pyrite but
yielded no significant results. The abundance of pyrite encountered in
drilling explains the IP chargeability anomalies; however, the areal
extent of the copper-gold-molybdenum soil anomalies remains
unexplained.

A sixth hole 700 metres to the south of the Grizzly Showing intersected
graphitic mudstones and disseminated pyrite with trace chalcopyrite
yielding no significant results. The remaining two holes in the Grizzly
Showing area were lost due to poor drilling conditions.

The Mirko Grid drill program targeted IP chargeability anomalies and
coincident molybdenum-in-soil geochemical anomalies in an area of
scarce outcrop exposure. Three holes were completed to test two
targets. GRZ08-08 and -09 intersected anomalous molybdenum
mineralization with an intersection of 94.44 metres that averaged 0.02%
molybdenum in GRZ08-09. Molybdenum-bearing mineralization in this
interval consisted of molybdenite fracture coatings and disseminations
within carbonate veins and breccias hosted by moderately
potassium-feldspar+sericite+chlorite+carbonate altered volcaniclastic
rocks.

GRZ08-10 was drilled 400 metres to the north of holes GRZ08-08 and -09
on the inferred continuation of the Mirko IP anomaly targeted in the
previous holes. This hole intersected a broad zone of
propylitically-altered volcanic rocks that did not return any
significant mineralization.

Inmet has indicated that it does not intend to proceed with further
exploration at the Grizzly.

"On behalf of the Rimfire team, I would like to thank Inmet for their
commitment in testing the Grizzly Property." said Jason Weber, Rimfire
President and CEO. "We are pleased that our relationship with Inmet
will continue through our recent agreement regarding the Barmedman
Property in the Lachlan Fold Belt, New South Wales, Australia. A
drilling program funded by Inmet targeting copper-gold mineralization
is currently underway at Barmedman."
