Rimfire Purchases Cangold's 51% Thorn Interest
======================================================================

PR08-07

Vancouver, BC -- April 14, 2008: Jason Weber, President and CEO of
Rimfire Minerals Corporation is pleased to report that Rimfire has
purchased Cangold Limited's 51% interest in the Thorn
gold-silver-copper property. Rimfire now has sole ownership of the 170
square kilometre property, subject to 3.5% underlying net smelter
royalties.

"Cangold has been a great partner at Thorn, however, their management's
geographic focus has shifted to take advantage of their strengths in
Mexico," stated Jason Weber, President and CEO. "Our team feels that
the geologic setting, intensity and breadth of alteration and
mineralization identified to date indicate a district-scale high
sulphidation gold-silver-copper system. We have regained full control
of the Thorn so we can bring in a new partner to aggressively explore
the project."

The Thorn property covers a large mineralizing system centred on a 60
square kilometre Late Cretaceous volcanic centre, 130 km south of
Atlin, British Columbia and 50 km north of the past-producing Golden
Bear gold mine. To date, 20 precious metal occurrences have been
identified on the property, including quartz-sulphide
copper-gold-silver bearing veins, breccia-hosted silver-lead-zinc-gold
mineralization, copper-molybdenum porphyry mineralization and
sedimentary replacement gold-silver-zinc mineralization. Together with
the wholly-owned Kizmet property, Rimfire now controls the key targets
in an underexplored epithermal district with excellent potential for
precious metal discoveries.

Cangold and Rimfire explored the Thorn from 2002 to 2005. Highlights of
these exploration programs include:


.. Discovery of high grade gold-silver-copper bearing
quartz-pyrite-enargite-tetrahedrite veins. This style of mineralization
is similar to that mined at Barrick Gold's 6.3 million ounce El Indio
gold deposit, Chile.

.. Precious metal-bearing alteration associated with high-sulphidation
veins cover an approximate area of 6000 by 6000 metres as indicated by
outcrop exposure, airborne resistivity data and induced polarization
surveys.

.. Demonstrated 3700 metres of aggregate strike length in 6 vein
corridors, with high grade mineralization intersected in drilling.

.. Just three holes in the Talisker vein corridor, with 500 metres
strike length indicated by geophysical data, yielding intersections of
4.44 g/t gold, 407.9 g/t silver, and 2.95% copper over 4.2 metres
(THN05-37) and 4.48 g/t gold, 65.3 g/t silver, and 0.65% copper over
3.6 metres (THN04-29).

.. Oban Breccia (breccia-hosted silver-lead-zinc-gold mineralization)
averaged 173.0 g/t silver, 1.2 g/t gold, 1.5% lead and 1.5% zinc over
25.2 metres in drilling. High grade mineralization on surface returned
6149 g/t silver, 3.48 g/t gold, 42.97% lead and 3.45% zinc from massive
sulphide boulders.

.. Bonanza grade gold (265 g/t gold, 631 g/t silver) from a barite
float sample has not yet been traced to a bedrock source. Highly
anomalous stream sediment samples have yet to be followed up.

.. 2000 by 500 metre multi-element soil (talus fines, defined by > 50
ppb gold) anomaly remains largely unexplained at the Outlaw zone, a
gold-silver-zinc target.


Management will be seeking a partner to advance the Thorn through
further drilling of drill-ready vein targets and further ground work to
prepare early stage prospects for drilling.

The terms of the purchase of Cangold's interest in the Thorn are
$100,000 cash upon signing of the agreement, and 100,000 shares of
Rimfire upon exchange approval of the sale of the Thorn interest.
Should Rimfire subsequently find a partner to explore the project,
Rimfire will pay 25% of any third party cash or share payments to
Cangold. Upon commercial production, Rimfire, at its election, would
issue a further 250,000 shares or pay $1,000,000 cash to Cangold
provided that Rimfire still holds at least a 10% interest in the
project.
