- Indicated Mineral Resources Increase 76% in West Zone

Starfield Resources Inc. (TSX: SRU : OTCBB: SRFDF) today released
a summary of its newly compiled National Instrument 43-101 2007
mineral resource for its Ferguson Lake property in Nunavut, Canada.

The document shows an indicated mineral resource estimate for the
property's Main West Zone of 15.2 million tonnes grading 0.71%
nickel, 1.04% copper, 0.08% cobalt, 1.64 grams per tonne palladium
and 0.28 grams per tonne platinum.

By comparison, the 43-101 report dated May 15, 2006 showed an
indicated resource of 8.7 million tonnes grading 0.67% nickel, 0.93%
copper, 0.08% cobalt, 1.47 g/t palladium and 0.21 g/t platinum.

The Company received the most recent result summary while the
co-authored Technical Report is in preparation for regulatory filing
within 45 days. Jaime Lavigne, P.Geo. and Qualified Person, updated
the resource estimate to include last year's 116 resource definition
diamond drill holes and 20 additional geotechnical holes. A total of
359 exploratory drill holes have been drilled to date.

André Douchane, President of Starfield Resources, said, "I am
extremely pleased that the 76% increase of the indicated mineral
resource in the Main West Zone has successfully demonstrated that the
infill drilling campaign can convert inferred mineral resources to
indicated resources. I am especially impressed that, despite our very
conservative modeling approach, indicated resources increased to 15.2
million tonnes from 8.7 million tonnes and the combined nickel and
copper grades increased to 1.64%.

"If we consider this project in today's metal price environment,
and take into account the massive size of the geological setting as
described by Dr. Allan Miller in Starfield's news release of May 28,
2007, along with the impressive strike length of the discovery and
the continuity of mineralization, the project becomes very, very

"The new estimate will be the cornerstone of Starfield's ongoing
scoping study that will evaluate the project on current (US$25/lb)
and intermediate (US$15/lb) nickel prices along with the US$7/lb used
in this resource estimate," Mr. Douchane said.

The Company intends to follow up on the potential of high-grade
platinum intercepts in the West Zone footwall with 3,000 kilometres
of drilling this summer, Mr. Douchane added.

Previously at Ferguson Lake, at a Cu+Ni cutoff grade of 1.0%,
Geostokos Ltd. (June 26, 2006) had reported 7.7 million tonnes of
measured and indicated resources and Dr. N.C. Carter (May 15, 2006)
reported 8.7 million tonnes of indicated resources. The current
resource estimate incorporates 1950-1957 historical data (173 drill
holes) and the data collected by Starfield (1999-2006) for 359 new
holes totaling 133,214 metres of drilling.

The 2007 mineral resource estimate methodology is a departure from
that used previously and will form the basis of evaluation studies
currently being undertaken by Scott Wilson of Roscoe Postle
Associates Ltd. (SWRPA).

(xx) Platinum, palladium, and cobalt not estimated for the East Zone
as the East Zone contains a higher proportion of historical INCO
holes for which cobalt or individual platinum or palladium grades
have not been determined.

Nickel, copper, cobalt, platinum, and palladium bearing
semi-massive to massive sulphides occur in lenses intercepted in
drill hole intersections over the 15.5 kilometre east-west strike
length across the Ferguson Lake property. For the purposes of the
current 2007 resource estimates, three separate domains of resources
are quantified. On the east side of Ferguson Lake, sulphide
mineralization occurs at surface and at depth in the East Zone that
now incorporates the various historical zones known as East Zone I,
East Zone II, M Zone and Pointed Lake. On the west side of Ferguson
Lake, West Zone sulphide mineralization occurs at surface and at
depth in the Main West Zone and at depth along the Extension West
Zone. The Main West Zone consists of a strike length of 2.7
kilometres while the Extension West Zone completes the 4.1 kilometre
long continuous mineralization of the West Zone.

Drill spacing in the East Zone and Extension West Zone is
irregular and comparatively widely spaced and as such limits the
interpretation of geological continuity of massive sulphide.
Resources in the East and West Extension Zones have been estimated
using the cross sectional polygonal method and have been classified
as inferred mineral resources. Resource cutoff for the East Zone and
Extension West Zone is based on economic and operating values and
parameters as described below for the Main-West Zone resource

Mineralization in the Main-West Zone occurs over a strike length
of 2.7 kilometres and plunges to the west. Drill spacing is variable
in the Main-West Zone including a detailed area where the drilling is
at 25 meter spacing (Pit Area) to a maximum of 100 metre drill hole
spacing. The density of drill hole data from the Main-West Zone
supports geological interpretation for the basis of mineral resource
estimation. The Main-Zone Pit Area has been the subject of a detailed
geostatistical resource estimation study, and is the area from which
historical indicated mineral resources have been estimated and quoted
from Ferguson Lake.

Mineralization in the Main-West Zone occurs as a number of stacked
sheets or lenses of massive sulphide with an East-West strike and
moderate north dip. For the purposes of geological interpretation
model building and subsequent resource estimation, only samples
containing 50% or more sulphide (i.e. sulphide abundance generally
logged by one-metre sample-interval-by-sample-interval basis) were
used to determine massive sulphide intersections. A total of 56
lenses and sheets of variable dimension have been interpreted across
the Main-West Zone. Two block models have been created to estimate
the resources in the Main-West Zone: one block model to estimate
potentially open pit-able resources from surface to a vertical depth
of 250 metres and the second to estimate potential underground
resources at depths greater than 250 metres. The geological
interpretation and block model resource estimation procedures
utilized for the Main-West Zone (and the East and Extension West
Zones) conform to industry best practices, CIM Definitions and
Standards, and National Instrument 43-101. Previous geostatistical
studies, as well as new statistical and geostatistical analyses, were
utilized for block grade estimation. Block density was estimated from
a specific gravity - metal grade regression relationship that was
established from the determination of specific gravity of 1,342
diamond drill core samples.

For the purposes of the Preliminary Economic Assessment (PEA) on
the Ferguson Lake project, Dr. Bryn Harris, metallurgical consultant
to Starfield in conjunction with SWRPA, were consulted to establish
economic, mining, and processing parameters for the project. Factors,
parameters, and values used to establish resource cutoff include in
the current estimate:

Resource Estimate Input Parameters
Metal Price per pound Recovery
Nickel US$7.00 93%
Copper US$1.75 93%
Cobalt US$15.00 64%
Operating Costs
Cost per tonne milled
Open Pit Mining CDN$75.00
Underground Mining CDN$110.00
US$/CDN$ Exchange Royalty Payable
Rate(equal sign)1.18 (equal sign) 3% NSR

It is important to note that the tabulated current resources are
based on 50% or greater sulphide contents of the massive sulphide
lenses and sheets and do not included any dilution or dilution
factors. Also, in the current PEA platinum and palladium are not
considered in the process and economic analysis and therefore do not
contribute to the NSR. Platinum and palladium were therefore not
considered and incorporated in the calculation of the resource cut
off value. However, platinum and palladium grades have been estimated
for the Ferguson Lake mineralization and are incorporated into the

Preliminary Economic Assessment

As previously reported on April 9, 2007, Starfield has
commissioned Scott Wilson of Roscoe Postle Associates Inc. to
complete a Preliminary Economic Assessment of the Ferguson Lake
project. The current resource estimate will form the basis for the
assessment to be completed by SWRPA and will provide the opportunity
for the evaluation of multiple scenarios including the evaluation of
the model with different mining scenarios and at multiple grade

Jamie Lavigne, P.Geo, consultant to Starfield Resources and
Qualified Person, completed the 2007 Ferguson Lake NI 43-101 2007
resource estimate.

John Nicholson, P.Geo of Nicholson and Associates and Qualified
Person, has managed the Ferguson Lake exploration programs since 1999
and is responsible for the drill program data collection, data
management, assay QA/QC and data verification.
