Castle Resources Provides Granduc Operations Update

TORONTO, ONTARIO--(Marketwire - Sept. 9, 2010) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company") is pleased to update investors about its ongoing exploration and drilling activity at the Granduc Project near Stewart, B.C.

The immediate objective of the drill program at Granduc is to test the down dip extent of the historical deposit beneath and to the south of the zones mined by Newmont and Esso between 1971 and 1984. Specifically, drilling is targeting Blocks 3 and 4, which include the A, B and C orebodies between the 2175 and 2600 foot level (above sea level) in addition to targeting Block 5, between 1600 foot elevation and 2175 foot elevation, which includes the F, A, B and C orebodies (see press release dated July 22, 2010, to learn more about historical non NI 43-101 resource estimates). Castle has engaged MinConsult Exploration Services and MoreCore Diamond Drilling Inc. to manage and execute the diamond drill twinning program at the Granduc. In addition, Castle has engaged SRK Consulting to review and analyze exploration objectives at the Granduc in preparation of calculating a NI 43-101 resource estimate.

"Since announcing the initial option transaction for the Granduc in July we have moved quickly to establish and begin a comprehensive drill twinning program," said Mr. Mike Sylvestre, President & COO of Castle Resources. "Our objective is to commission a preliminary NI 43-101 resource estimate based on the results of this year's program which will confirm the presence of a large and potentially mineable copper and precious metal resource at the Granduc."

• Newmont and Esso Minerals operated the Granduc Mine between 1971-1984; processed over 15 million tonnes of ore grading 1.71% Cu; produced 420 million pounds of copper (plus gold and silver credits); the mine was closed in 1984 due to low copper prices
• Operators of the Granduc Mine invested over $115 million from Oct 1965 until start-up operations began in 1971
• 16 km haulage tunnel remains in good condition today
• Mining operations at the Granduc Mine consisted of crushing underground then processing of up to 9000 tpd. The concentrate was trucked 32 miles on an all weather road to the year-round deep sea port facility in Stewart which remains in operation today
• Bell Copper's exploration activities between 2004 and 2007 have confirmed mineralization within 4 kms to the north and south of the main Granduc orebody

Castle also wishes to announce that pursuant to the terms and conditions of its Stock Option Plan, it has granted, in the aggregate, 300,000 incentive stock options (the "Options") to a director and consultant of the Company.
