VANCOUVER, British Columbia, May 20, 2005 (PRIMEZONE) -- During Phase II of Starfield's (TSX-V:SRU) (OTCBB:SRFDF) 2004 exploration of the West Zone, holes were diamond core drilled on grid lines 62+50W and 61+50W to test a Crone SQUID geophysical survey anomaly identified on Line 62+00W. Interpretation and numerical modeling of this survey indicated that two conductive "plates" are required to match the field data which showed a northerly-dipping, strong conductor of extensive strike length. The assay results for the drilling of this strong geophysical conductor are reported in the following table.

A borehole PEM (Pulse Electromagnetic) geophysical survey of hole 04-210 produced a crossover occurring at 750 meters down the hole where the conductor grades 1.794% copper and 1.012% nickel and 2.70 g/t 2 PGEs over an intercept of 7.52 meters. At hole 04-214, located 100 meters away from 04-210, it is interesting to note that at 724.2 meters downhole, an almost identical intercept of over four meters graded 1.719% copper and 1.01% nickel.
In 2005, Starfield Resources will continue to use both borehole and ground SQUID geophysics to guide its drilling of the West Zone and "Pit Area."
