Starfield Resources Achieves Positive Recoveries From the Hydrometallurgical Test Processing of Ferguson Lake Massive Sulphides

Vancouver, Canada (ots/PRNewswire) - Starfield Resources Inc.
(TSX.V: SRU and OTC BB: SRFDF) ("Starfield" or "the Company") today
announced the successful hydrometallurgical bench-scale test
extraction of base metals from the Ferguson Lake Cu+Ni+Co+ Platinum
Group Metal (PGM) -bearing massive sulphide mineralization and the
subsequent production of high purity nickel and copper metal from
the process solutions.

Under the direction of Dr. Bryn Harris (metallurgical process
consultant) the Company continues to test its own newly-developed,
chloride- based, metallurgical treatment process. The 2006 program
has resulted in laboratory recoveries ranging from 98% to 99.8% for
copper and nickel and 60% to 70% for cobalt from sulphide core
samples. During the two-stage treatment process, the PGMs remain in
the residue (10% of original mass of sample) as a precious metal
concentrate with a grade of between 30 to 50 grams per tonne of
palladium plus platinum. Separate electrolytic nickel and copper
(99.99% purity) metal coupons (wafers) have been produced from the
hydrometallurgical treatment solutions.

Glen Indra, President of Starfield, said "We are delighted with
this year's progress on the hydrometallurgical testing of Ferguson
Lake massive sulphides and look forward to the production of more
metal from the continuous, second-stage, demonstration miniplant
during the first quarter of 2007." Mr. Indra further added "Our
process appears to be metallurgically and energy efficient as well as
being environmentally friendly because the valuable products
recovered using this method are base metals and PGMs plus by-products
iron and sulphur. This process is carried out at atmospheric
pressures thus eliminating the need for an autoclave and pressure
leaching system."

Dr. Bryn Harris, the company's Qualified Person under NI 43-101,
has prepared the information contained in this Press Release and is
in the process of preparing reports for the Company.

Summary of Testwork

Sample Preparation:

Starfield provided, HQ-sized core samples of massive sulphide
mineralization (from holes drilled on the west side of Ferguson Lake
in the potential "pit area") which were crushed and ground to 100%
passing through 100-mesh screens. Initial work utilized bench-scale
sized batches. A large scale sample (450 kilogram) was prepared this
Fall for a scaled-up, first-stage, leaching program at COREM
(certified mineral processing research services facilities) in Quebec
City.

Hydrometallurgical First Stage Leaching:

In the first stage, chloride-based, leaching process, the sulphide
mineral pyrrhotite and some pyrite are extracted into solution
effectively removing 90% of the iron and 80% of the sulphur from the
sample. The first stage unleached residue (concentrate) contains the
base metal sulphides of copper (chalcopyrite), nickel (pentlandite),
some pyrite, gangue and precious metals (PGM). The leach solution is
processed for acid recovery and lixiviant regeneration and recycled
back into the primary leach circuit.

The first stage leaching is an "environmentally friendly" process.
It produces iron in the by-product form of hematite and/or magnetite
(environmentally safe for on site disposal). Secondly, the liberated
gas can be used to produce by-product energy and elemental sulphur,
again an environmentally safe product for on site disposal. The first
stage of the process serves to significantly reduce the disposal
problems normally associated with the traditional flotation treatment
of iron sulphide minerals.

Hydrometallurgical Second Stage Leaching:

The 4 to 6 hour second stage, chloride-based leach process treats
the upgraded concentrate residue produced in the first stage,
pyrrhotite- specific, leaching process. The copper, nickel and cobalt
metals are extracted into the second stage leach solution while the
precious metals, most of the pyrite and gangue remain as a final
residue (solid). Ion-exchange processing recovers the base metals
from the second-stage leach solution, with copper and cobalt
separated first followed by nickel separation. To demonstrate the
potential to recover high value, high purity, metal at the mine
site, the ion exchange strip solutions were treated using
conventional electrowinning technology to produce separate specimens
of high purity nickel and copper metal. Laboratory recoveries
ranging from 98% to 99.8% for copper and nickel and 60% to 70% for
cobalt have been achieved in the lab-scale program. Additional
research is scheduled to develop physical concentration and/or
chemical treatment of the precious metals-PGM at the mine site.

Ongoing Program

The large scale, first stage, leach program of 450 kilograms of
massive sulphide mineralization is nearing completion and about 90
kilograms of residue (concentrate) has been produced. This product
will be feed material for a continuous second stage demonstration
miniplant which is currently being assembled for leach treatment and
ion exchange processing.

Mr. Bruce Ballantyne, Project and Business Development Manager,
stated "In 2007, the company's progress will continue with
confirmation of the established flow sheet, metallurgical and energy
balance performance studies and engineering cost estimates. We are
committed to the concept that hydrometallurgical processing of
sulphide ores is an achievable objective for a long-life project such
as Ferguson Lake and fits well with sustainable development in
Nunavut."

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 131,000 metres of diamond drilling in 359 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.
