Rimfire Commences Drilling At Walmer Property

VANCOUVER, BC - Rimfire Minerals Corporation reported that drilling has commenced at the Trounce gold prospect on the Walmer Property, Australia. The Walmer Property is located 40 km south of Dubbo, in New South Wales. Up to five diamond drill holes totalling 500 metres are planned to test this target.
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. The Trounce prospect consists of 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.
Float samples of quartz veining and silicified sediments 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. On surface, the showing occurs within 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. Surface rock and soil samples with anomalous gold values extends, but does not limit the potential strike length of the system to 750 metres.
Drilling was recently completed at the Grizzly property in northwest British Columbia. This work program was funded by partner Inmet Mining Corporation and consisted of 10 holes totalling 2120 metres of drilling to test the Grizzly and Mirko Grid targets for their potential to host copper-gold alkalic porphyry mineralization similar to other deposits in the area, such as Galore Creek. Surface results from the Grizzly Showing, located four kilometres from the Galore Creek access road include 38 metres averaging 0.74 % copper and 1.1 g/t gold from chip sampling. Assays from the current program are pending.
