RE-ANALYSES AND CHECK ASSAYS CONFIRM SIGNIFICANT PGE’s
IN WEST ZONE FERGUSON LAKE
Starfield Resources Inc. has received further verification of high-grade palladium-platinum-rhodium concentrations reported in drill hole FL01-101 (reported October 3, 2001 and April 24, 2002).
Reject sample material from the low-sulphide, biotite-rich high-grade PGE intercept were sent to Activation Laboratories. Nickel Sulphide Fire Assay fusions followed by INAA and ICP/MS analytical instrument determinations were the methods used to check PGE contents, in particular, rhodium concentrations. These latest results as well as previous data received from other accredited laboratories using different analytical methods are presented below:

These check assay results verify that the various analytical procedures used by these accredited laboratories consistently confirm the significantly high concentrations of rhodium (Rh) as well as palladium (Pd) and platinum (Pt) in this distinctive zone. The current drilling program is designed to further identify the target both east and west of the original intercept.
Starfield Resources has also received confirmation re-analysis, check assay, results for hole FL01-99 completed in August of 2001. The hole is located at 8+56 North on section 62+00 West and was drilled at an angle of -80 degrees on an azimuth of 176 degrees to a depth of 869 meters.
The objective of hole FL01-99 was to further test West Zone at depth below hole FL01-84 which had intersected a 46-meter interval of massive and stringer sulphides grading 1.34% Cu, 0.76% Ni, 0.089% Co, 1.99 g/t Pd and 0.32 g/t Pt.
Initial results for the massive and stringer sulphide interval in hole FL01-99 were provided by Bondar Clegg Canada Limited. A four acid sample digestion was followed by initial multi-element geochemical ICP analysis and subsequent
assays of samples with values exceeding 5000 ppm for copper and 4000 ppm for nickel. Palladium and platinum in parts per billion were determined by fire assay fusions using a silver inquart collector and ICP-AES determinations.
Sample pulps from the 31.96-meter interval (34 samples) were submitted to both ALS Chemex and Acme Analytical Laboratories for accredited check analyses.
ALS Chemex multi-element geochemical results were determined by four acid sample digestion followed by ICP-AES/MS determinations. Sample analyses containing greater than 10,000 ppm Cu were re-assayed for Cu and this data is incorporated below. Palladium and platinum were determined in parts per billion by Fire Assay fusions using a silver inquart collector followed by ICP-MS determinations.
Acme Analytical multi-element geochemical results were determined by an aqua regia acid sample digestion followed by ICP-MS determinations. Geochemical results are reported for Cu and Pd as Ni and Pt concentrations are only partially extracted using aqua regia acid digestions.
Weighted average values for three sample intervals based on results from the three ISO9002 registered laboratories are presented in the following table:

The re-analyses results are in good agreement with the initial analytical and assay data now reported for FL01-99. Starfield Resources Inc. will continue to monitor PGE and base metal data from both low-sulphide and massive sulphide zones as intercepted in the current phase of drilling.
