REPEAT: Castle Resources Announces Positive Preliminary Economic Assessment for the Elmtree Gold Project

- Micon International’s PEA confirms robust economics at Elmtree

- Management fast-tracking Elmtree to bankable feasibility this year

- Permitting process has begun at the Elmtree Project for open pit plan

TORONTO, ONTARIO--(Marketwire - March 8, 2010) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company ") is pleased to announce the results of its NI 43-101 compliant Preliminary Economic Assessment ("PEA") for its Elmtree Gold Project near Bathurst, New Brunswick. The independent PEA was completed by Micon International Limited ("Micon") of Toronto, Ontario.

Management commissioned the Micon PEA to determined baseline economics of the Elmtree project. The PEA indicates a pre-tax IRR of 25% using $900 Au/oz and a pre-tax IRR of 63% using $1,100 Au/oz, based on open pit mining and processing of 1.117 million tonnes with an average gold grade of 2.41 g/t Au, a stripping ratio of 6.3 (W/O), and assumes a 90% Au recovery and a 60% Ag recovery.

Highlights from Micon's Elmtree PEA at 100% interest include:

Gold Ounces 85,000  
Silver Ounces 17,000  
Mine Life 15 months  
Development Time 12 – 15 months  
(Feasibility & Permitting)    
 
Price of Gold $900 /oz $1,100 /oz
Price of Silver $12 /oz $16 /oz
 
CAPEX LOM $3 million $3 million
OPEX LOM $45 million $45 million
 
Gross Sales $73.8 million $90 million
Net Cash (pre-tax)* $7.6 million $23 million
IRR (pre-tax) 25% 63%
NPV (8%) $3.8 million $14.3 million

* after return of Capital Expenditures (CAPEX)

The Micon study is based on the extraction of NI 43-101 compliant Indicated and Inferred resources through a bulk tonnage, open-pit mining scenario. The study suggests that the best economic return can be achieved with a toll milling strategy that significantly reduces CAPEX for a project of this size. All the results presented in this release assume toll milling at an existing facility for the production of a sulphide concentrate and its sale to a nearby smelter. The PEA also considers a base case that includes a processing plant and tailings facility at Elmtree. The Elmtree Gold Project is located in a favourable mining jurisdiction with excellent local milling and processing infrastructure, including power, roads and a skilled work force.

"We are very excited by the economic returns laid out by Micon for the Elmtree Project," said Mr. Stephen Shefsky, President & CEO of Castle Resources Limited. "Our goal now is to advance the project towards bankable feasibility within 12 months with the aim of beginning production at Elmtree in the next 18 months."

Castle is in the first year of a 3 year option agreement with Stratabound Minerals Corp. to acquire up to a 70% interest in their 100% owned Elmtree Gold Property (see press release dated June 12, 2009). The Elmtree property (85 claims, 1,375 hectares) hosts at least three gold-bearing zones, the higher grade West Gabbro Zone, original Discovery Zone and the larger tonnage, lower grade South Gold Zone. In 2008 a NI 43-101 compliant resource estimate prepared by Mercator Geological Services Limited (Mercator) reported 525,000 Indicated tonnes in the West Gabbro Zone grading 2.45 g/t gold; 1,556,000 Inferred tonnes in the West Gabbro Zone grading 2.01 g/t gold; 2,367,000 Inferred tonnes in the South Gold Zone grading 0.74 g/t gold; 583,000 tonnes in the Discovery Zone grading 1.15 g/t gold only, as well as 117,000 Inferred tonnes in the Discovery Zone grading 1.77 g/t gold, 44.36 g/t silver, 0.78% lead and 2.17% zinc. Mercator's estimate was used by Micon as the basis for the PEA. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The PEA is reported in accordance with Canadian Securities Administrators' NI 43-101 and mineral resources have been classified in conformity with generally accepted CIM "Estimation of Mineral Resource and Mineral Reserves Best Practices" guidelines. Gold and silver grades were estimated using inverse power of distance constrained by geologic shapes constructed at reasonable cutoffs.

The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves. The PEA was prepared by Sam Shoemaker Jr., Victor Bryant and Christopher Jacobs of Micon. A copy of the Technical Report will be available on SEDAR within 45 days.
