(All figures in Australian dollars) Rimfire Minerals Corporation (TSX
VENTURE:RFM) is pleased to report that Inmet Mining Corporation has signed a
Farm-in agreement on the Barmedman Property, in New South Wales, Australia.
Under the terms of the agreement, Inmet can earn a 60% interest by funding at
least $5 million in exploration on the property over four years, including
$400,000 in the first year. Inmet will make staged cash payments totalling
$250,000 over the earn-in period, including $50,000 upon signing of the
agreement. The Barmedman deal marks the second option agreement between Rimfire
Minerals Corporation and Inmet Mining.


The Barmedman Property is located in a corridor within the Lachlan Fold Belt
characterized by regionally-extensive alteration and clusters of both
copper-gold porphyry and high sulfidation occurrences and deposits. Within this
corridor Rimfire has identified a 0.5 km by 2.4 km Induced Polarization (IP)
chargeability anomaly coincident with a copper-gold Mobile Metal Ion (MMI)
geochemical anomaly. This IP anomaly occurs in an area of no outcrop and deep
overburden cover and has not been tested by previous drilling. Rimfire and Inmet
are planning to conduct diamond drilling to determine whether the IP
chargeability anomaly reflects buried copper-gold mineralization. A preliminary
diamond drilling program consisting of 1200 metres of drilling in four holes is
planned for March-April of 2009. In addition, further geochemical techniques,
such as MMI geochemical surveys are being contemplated to investigate the entire
388 km2 property.


The Barmedman Property was one of nine exploration licenses acquired in 2007
based on targets identified in a Neural Network study conducted within a 120,000
km2 area of interest in New South Wales, Australia. Rimfire completed IP
geophysical surveys and MMI geochemical surveys over the core of the Barmedman
Neural Network target in 2008. Recent drilling adjacent to the Barmedman
tenement by Goldminco Corporation has identified numerous porphyry copper-gold
prospects. Management believes that these discoveries attest to the mineral
endowment of the belt and the potential for similar mineralization on the
Barmedman Property held by Rimfire.


Walmer Property, Australia Update

Rimfire Minerals Corporation has completed its 2008 diamond drill program which
tested the Trounce target on the Walmer property located in New South Wales
Australia. The Trounce prospect is a small outcropping of silicified sediments
with quartz - pyrite veining and stockwork. Two of seven grab samples from the
showing returned gold values of 2.4 and 3.6 g/t gold and the remaining five
assayed from 0.21 to 0.61 g/t gold. Based on the grab sample results and the
ability for a low cost diamond drill program due to accessibility, Rimfire felt
it would be practical to drill the prospect in order to determine sub-surface
geology and prospect potential. The drilling program consisted of 286.6 metres
of drilling which returned no significant results and no future work is planned
at Trounce.
