Rimfire Completes Drilling at The Walmer Property

VANCOUVER, BC - Rimfire Minerals Corporation, reported 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.
