VANCOUVER, British Columbia, May 19, 2005 (PRIMEZONE) -- Starfield Resources Inc. (TSX-V:SRU) (OTCBB:SRFDF) has compiled final assay results from the gabbro-hosted footwall mineralization intersected in the last 9 holes of the 2004 definition drilling campaign in the "Pit Area" of the West Zone. Highlights are shown in Table I and complete data is shown in Table II.

Footwall mineralization assay results for 32 holes were reported in Press Release SRU-04-05, February 4, 2005.
The footwall mineralization discovered in 2004 is characterized by variable platinum and palladium concentrations with significant platinum in most holes. Also, the platinum content within the footwall massive sulphide mineralization appears significantly higher than in the other West Zone massive sulphide lenses. An example is hole 04-202 (see Tables I & II) where 10.82 meters of footwall massive sulphides grade 1.39% copper, 1.05% nickel, 2.67 g/t palladium and 0.79 g/t platinum with a one-meter intercept grading 4.84 g/t platinum. This hole also contains low sulphide-PGE (LS-PGE) bonanza-grade mineralization such as the one-meter intercept grading 7.65 g/t palladium and 10.13 g/t platinum (Table II).
The Company is pleased that during 2004 LS-PGE bonanza-grade intercepts were discovered over one kilometer of strike length. These often occur within broad zones of LS-PGE mineralization grading between 2-6 g/t 2 PGEs or within narrow one-meter widths. True thicknesses of the footwall-style mineralization are not yet known in this new discovery.
Continued "Pit Area" drilling is planned in 2005 to better define the nature of the unique and important footwall PGE-enriched mineralization found at Ferguson Lake.
Details concerning drill core sampling, sample preparation, accredited laboratory geochemical and assay analytical methods, QC and QA procedures can be referred to in detail in Press Release No. SRU-07-04, June 10, 2004, page 3.
