VANCOUVER, June 26 /CNW/ - Starfield Resources Inc. (TSX.V: SRU and OTC
BB: SRFDF) ("Starfield" or "the Company") today announced that world renowned
Dr. Isobel Clark of Geostokos Ltd., Scotland, has provided Starfield Resources
with a summary of a Detailed Technical Report "Statistical and Geostatistical
Analysis of Ferguson Lake Project." In the most densely drilled portion of the
potential "Pit Area" of the West Zone between grid lines L40+00W and L51+00W
and to a depth of roughly 120 meters, Geostokos reports that at a 1% Cu+ Ni
cutoff grade a total of 7.79 million tonnes could be estimated in the Detailed
Study Area as being in the "measured and indicated" categories (measured(equal sign) 3.75
million tonnes; indicated(equal sign)4.04 million tonnes).
"This marks the first time that measured resources have been determined
for the Ferguson Lake Project," said Glen Indra, Starfield's President and
CEO. "The Company believes that with the appropriate detailed drill spacing,
as now implemented in the ongoing 2006 drill program, both measured and
indicated resources in the potential "Pit Area" will significantly increase."
Dr. Clark visited the Cu+Ni+Co+Pd+Pt property in 2005 and her 2006
geostatistical investigation examined the complete property-wide data set
containing 18,561 core sections totaling 21,102 meters of core drilled and
assayed. The final report will include general analyses of the property-wide
data set and various sub-regions including a "Detailed Study Area" where 9
more closely spaced geostatistical holes were drilled at the end of the 2005
season.

The Geostokos Detailed Study was commissioned to:

    a) Determine what criteria should be set for classifying volumes of
       rock as "measured" and what proportion of the area could be then
       estimated as a "measured resource category".

    b) Determine what density of sampling (drilling) would be needed to
       ensure adequate grade control to design a mining operation.

Dr. Clark studied data from 3,548 core sections in the Detailed Study
Area down to a depth of more than 300 meters. The breakpoint between
background values in the rock and mineralization was established as 0.1%
copper. The sections averaged just short of a meter in length having grades
higher than 0.1% copper plus nickel.
In the Detailed Study Area a mining unit of 10x10x10 meters was used as a
block size and approximately 20,000 blocks were estimated. Block estimate
classification of "measured" occurred if the kriging variance fell below the
total sill of the semi-variogram (ygiagam) and at least 4 boreholes fell
within the search ellipse. Blocks not classed as "measured" but within the
range of influence of the boreholes were classified as an "indicated"
category. Any blocks not meeting these criteria were not within the scope of
the Detailed Study as they are classed in the "inferred" category. Due to the
wide spacing of drill holes along the one kilometer drilled strike length in
the pit area of the Low Sulphide PGE-rich horizon, sections do not yet have
the criteria necessary to fit "measured or indicated" categories.
Relevant tonnages calculated during the Detailed Study used a 4.1
specific gravity for the sulphide mineralization based upon copper and nickel
values at cutoff grades of 1.0%, 1.5% and 2.0% Cu+Ni. Detailed figures were
calculated for the volume of mineralization down to sea level (a depth from
surface of roughly 120 meters).
Of the 9,657 blocks examined 1902 were classified as "measured and
indicated" at a Cu+ Ni cutoff grade of 1.0%. These blocks were estimated to
contain 7.7 million tonnes grading 0.96% Cu, 0.57% Ni, (Cu+Ni (equal sign) 1.53%), 0.04%
Co, 0.87 g/t Pd and 0.13 g/t Pt. Included in the total tonnage is 1.35 million
tonnes and 0.42 million tonnes of "measured" resources at 1.5% and 2.0% ,
respectively, Cu+Ni cutoff grades and 1.62 million tonnes and 0.46g million
tonnes of "indicated " resources at 1.5% and 2.0%, respectively, Cu+Ni cutoff
grades. The Company has reported NI 43-101 compliant property-wide "indicated"
resources of 8.7 million tonnes and "inferred" resources of 66.1 million
tonnes at a 1.0% Cu+Ni cutoff grade (Dr. N.C. Carter Ph.D., P.Eng., May 15,
2006). It should be noted that the property-wide resource calculations made by
Dr.N.C. Carter were not constrained by area, depth or block model size as
determined in the Geostokos Detailed Study parameters.
Dr. Clark's summary report also found that "the layout of samples for
"measured" blocks determined that a regular intersection of the mineralization
by boreholes on a 22-25 meter grid would provide adequate sampling for mine
planning and grade control purposes."
With the results of this encouraging investigation, the company now has
two drills operating in the potential "Pit Area" (Line 39+00W to L 60+00W).
Now guided by these results and the recommended drill pattern spacing for
quantifying "measured" resources, Starfield has a confirmed strategy to
delineate "starter pit" resources within the "Pit Area" as the 2006 priority
plan.
The Company intends to file the complete Geostokos Technical Report on
SEDAR within 45 days.

About Starfield

Starfield Resources Inc. is an advanced exploration and development
company focused on its Ferguson Lake Copper-Nickel-Cobalt-Palladium-Platinum
property located in Nunavut, Canada. The Ferguson Lake property covers more
than 1.3 million acres and is 100%-owned by the Company. Since 1999, Starfield
has completed 104,000 metres of diamond drilling in 243 holes. A NI 43-101
technical report dated May 15, 2006 by N.C. Carter PhD., P.Eng. was filed on
SEDAR and on the Starfield website on May 25, 2006. A developing feature of
this mineral district is the significant discovery of high-grade platinum and
palladium mineralization found in the footwall to the massive sulphide
deposit. Starfield's Ferguson Lake Project is unfolding as Nunavut's largest
ongoing base and precious metal project.
