Successful Results Announced from Continuous Hydrolysis 
Circuit
 

TORONTO, Oct. 30 - Starfield Resources Inc. (TSX: SRU / OTCBB: SRFDF) today released successful results from the refinement of the hydrolysis circuit in its hydrometallurgical process intended to treat massive sulphide ore from the Company's Ferguson Lake property in Nunavut.

"We are having a banner year with our Ferguson Lake project and I couldn't be more pleased with our progress," said André J. Douchane, President and CEO. "Dr. Harris and his team have created the basis for a new era in metal recovery wherein efficiency is key and the environment is better protected than ever before."

Update on Iron Hydrolysis Testing

Testing of the continuous circuit for iron hydrolysis, precipitation and hydrochloric acid recovery has been ongoing in Montreal for the past two months. Initial results are encouraging, and further testing is planned to continue for the remainder of 2008.

"After over two years of extensive laboratory development work, Starfield has achieved a real breakthrough in hydrometallurgical research," saidMichael Moran , Starfield's Director of Engineering. "With this process we can now take a difficult massive sulphide ore and produce pure nickel, copper and cobalt products in a cost-effective, environmentally friendly and energy-efficient manner."

The hydromet processing plant is designed to extract pure, LME-grade nickel, copper and cobalt metals from massive sulphides at competitive production costs. The process will allow for economical operations at Starfield's proposed mine and hydrometallurgical plant sites, and produce by-product electricity to power both the plant and the mine, with some excess electricity remaining for potential sale to local communities.

Dr. Bryn Harris, B.Sc., Ph.D., FCIM, FIMMM, C.Eng, is the Qualified Person for the hydrometallurgical process and has reviewed this news release in accordance with NI 43-101.

In March of this year, Starfield released a summary of the preliminary economic study (scoping study) which, using a base case model, estimated a pre-tax IRR of 13.4% with approximately CDN$266 million of pre-tax cash flow per year. In the same release, the Company also estimated a pre-tax IRR of 27% with about CDN$536 million of pre-tax cash flow per year by using then current prices for nickel and copper. Since March, nickel and copper prices have declined to levels below those used in theMarch 20, 2008 press release; however, other products considered in the cash flow analysis either remained the same or increased in value. Revisiting the scoping study model used in theMarch 20, 2008 release, with current commodity prices and exchange rates, shows a pre-tax IRR at 34.3% with approximately CDN$697 million of pre-tax cash flow per year.

A comparison of the effects of commodity price changes to the base case model is outlined in the table below.

The pre-tax NPV at a 10% discount rate would increase from CDN$1.94 billion using the March numbers to CDN$2.99 billion using current prices. The pre-tax NPV at a 15% discount rate, using current prices, is CDN$1.7 billion.

"These numbers clearly demonstrate the value of the hydrometallurgical process we intend to use at Ferguson Lake," added Mr. Douchane. "This process, with its economically diverse commodities, clearly helps to stabilize the project's positive economics. While the copper and nickel prices are considerably lower than even those contemplated in the base case, the project economics remain positive because of the rise in the price of sulphuric acid, and the decline of the Canadian dollar against the U.S. dollar."

About Starfield

Starfield Resources Inc. is an advanced exploration and development stage company focused on its Ferguson Lake nickel-copper-cobalt-platinum-palladium property in Nunavut,Canada . The property is emerging as Nunavut's largest ongoing base and precious metal project. Starfield has funded the development of a novel, environmentally friendly and energy-efficient hydrometallurgical flow sheet to recover metals from its Ferguson Lake massive sulphides.

The Company will be filing an amendment to its scoping study to reflect the project's sensitivity to more volatile commodity prices.
