Starfield Resources Inc.: Metallurgical Testwork of
'Pit Area' Footwall Mineralization Yields Excellent
PGE Recoveries

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 10, 2005) - Starfield

During the 2004 second phase of delineation drilling of the "pit area"
of the West Zone, Starfield drilled a "Metallurgical Hole" (Hole
04-188:location 45+80W/1+95N) in order to obtain suitable Platinum Group
Element (PGE) enriched footwall mineralization to conduct metallurgical
and mineralogical testing. The Company has engaged Dr. Evan Kirby of
Metallurgical Management Services, Perth, Australia to design, plan and
supervise the testwork program undertaken by SGS Lakefield Research
Africa at their Johannesburg Laboratories, SA.

Dr. Kirby in a technical note and Progress Report (Dr. Evan Kirby,
MMS-SRU-03, February, 2005) has documented that preliminary results from
the metallurgical test program show excellent PGE recovery results
achieved in rougher and cleaner froth flotation testwork on the
PGE-bearing Low Sulfide Zone (LSZ) footwall material. The LSZ-PGE
bearing zone tested from Met-hole 04-188 was 15 meters in length grading
5.99 g/t 2 PGE (2.61g/t Pt+3.38g/t Pd).

Result: - Rougher flotation,
90% (Pt + Pd) Recovery and 45 g/t (Pt + Pd) concentrate

- Open circuit cleaner flotation with three stages of
421 g/t (Pt + Pd) concentrate grade and 68% (Pt + Pd)

The preliminary 04-188 LSZ met test results were obtained from flotation
testwork with no attempt at optimizing process parameters such as the
fineness of grind and reagent additions or locked cycle circuit tests.
Dr. Kirby's assessment of the preliminary results is that:

- they compare favorably to the laboratory flotation of South African
Merensky Reef ores.

- they exhibit excellent flotation kinetics (fast) and recoveries (high)
and were achieved with low reagent additions (potential low costs), and

- they are amongst the best PGE recovery/grade results that he has seen.

Promising results have also been obtained from rougher flotation work on
Footwall Massive Sulfide Zone (FMSZ) material obtained from a 1.3 meter
interval from Met-Hole 04-188 which graded 3.07g/t 2PGE (see Table One
for comparative "Head Grades "). Dr. Kirby reports that for this
PGE-bearing massive pyrrhotite rich material "selective flotation could
form the basis of a commercial recovery process." (MMS-SRU-03, February,

The metallurgical samples from Met-hole 04-188 are similar to the
intervals of PGE-bearing footwall-style of mineralization first
discovered in drill hole 03-157(see Appendix One), These holes are
effectively duplicates as the drill collars are 0.3 meters apart with
borehole survey data suggesting that the holes are about a meter apart
where they intersect footwall mineralization. The Ferguson Lake footwall
mineralization is characterized by the more important LSZ intercepts of
greater widths and platinum contents compared to the FMSZ mineralization
(Appendix One). The LSZ is notable for its low sulphur content (1.23%)
as compared to the FMSZ contents of 16.85% due to massive pyrrhotite
(Table One). It is important to note that Ferguson Lake PGE-bearing
footwall mineralization generally lies 30-50 meters below the base of
the main massive sulphide lens(es) which globally across the property
are estimated to contain 2.4 million ounces of palladium and 0.4 million
ounces of platinum at a 1% Cu+Ni cutoff grade (Dr. N.C. Carter, April 8,
2003 and reported in News Release SRU-10-03, June 6, 2003). Head assay
and analyses of the two footwall PGE-bearing styles of mineralization
areas are shown below in Table One.

Dr. Kirby has provided a general technical synopses regarding PGE
recovery by flotation. Grinding followed by froth flotation are the
metallurgical processes commonly used to produce saleable concentrates
from PGE ores. The ore is first ground to a fine powder to liberate PGE
and base metal (copper, nickel, cobalt) sulfide values. Reagents are
then added which cause the valuable mineral particles to attach to
bubbles and be recovered as a concentrate in the froth flotation
process. The flotation process commences with "rougher flotation" to
produce a low-grade concentrate which is then upgraded by a number of
stages of "cleaner flotation".

In a commercial process, the tailings from a cleaning step are usually
returned to the feed of the preceding step. Standard laboratory batch
testwork is conducted with open circuit cleaning, i.e. with no recycle
of the cleaner tailings. Locked cycle laboratory testwork involves a
sequence of repeated rougher and cleaner flotation with recycle of
cleaner tailings to simulate the commercial process. Compared with the
open circuit tests, locked cycle testwork usually gives significantly
improved concentrate grade and recovery.

Additional testwork including locked cycle flotation and advanced
mineralogical evaluation is planned for Met-Hole 04-188. The detailed
mineralogical examination of the concentrates and head ore will assist
in finer tuning of these non-optimized flotation processes and provide
mineralogical information as to the probable linkage between the PGE
endowment in the footwall mineralization and that found in the main base
and precious metal bearing massive sulphide zone. The success of the
strategy of selective flotation on the pyrrhotite-rich FMSZ material has
prompted the Company to submit main zone massive sulphide "pit area"
mineralization for similar flotation testing and evaluation. In 2004,
four metallurgical test holes (totaling 496 meters) utilizing HQ-sized
core were drilled in the 40+85W/1+40N area of the "pit area" where drill
hole 03-159 intercepted 20.95 meters of massive pyrrhotite grading 1.53%
copper, 0.97% nickel, 0.09% cobalt, 2.49g/t palladium and 0.24g/t
platinum. Approximately 3700 pounds of main zone massive sulphide HQ
core have been stored for metallurgical test purposes. Approximately 100
pounds of this material is presently being evaluated by flotation at SGS
Lakefield Research Africa.

The Company is very pleased with the program of preliminary testing and
the ongoing work now under way under the supervision of Dr. Evan Kirby.
His extensive experience world-wide in PGE recovery metallurgical
applications has assisted him as consulting metallurgist at Aquarius
Platinum Limited in their successful low-cost mining and processing of
various African PGE ore types. Starfield management recently visited the
staff and excellent laboratories and metallurgical testing facility at
SGS-Lakefield Research Africa. They provide corporate clients with their
extensive knowledge of PGE recovery systems for the famous SA Bushveld
Complex (UG2-Reef, Merensky Reef) and Great Dyke, Zimbabwe

Starfield Resources acknowledges that these PGE flotation results are
from only a single hole of footwall-style mineralisation. However,
visual core inspection and PGE assays from other intersections along a
considerable strike length in the West Zone "pit area" show broadly
similar characteristics and continuity. A more definitive level of
evaluation including variability testwork on a number of sections along
strike is planned. The present ongoing evaluation should prove useful
for scoping study purposes. The economic potential of the footwall
PGE-bearing mineralization appears to be very significant since it is a
relatively new discovery in the Ferguson Lake Mineral District. The LSZ
is amenable to normal grinding and has excellent flotation kinetics
(fast) and recoveries (high) achieved with low reagent additions (low
costs). These aspects are a significant step in adding to the asset
value of this unique mineral district.
