Castle Resources Announces South Zone Drilling Begins at Granduc Copper Project

- Leduc Exploration Camp Has Been Mobilized and Is Now Operational

- 2 Diamond Drills Now Targeting South Zone Copper Mineralization; Initial Assays Expected in July

- North Zone Drilling to Begin in June

TORONTO, ONTARIO--(Marketwire - May 22, 2012) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company") is pleased to announce drilling has begun at its 100% owned Granduc Copper Project near Stewart, British Columbia.

The initial focus of the 2012 drilling program is to drill test and expand upon the resource areas in the South Zone not drilled during 2011. Approximately 6500 metres is planned to be drilled in 12 holes with 2 drills set up on the South Leduc Glacier. In early June, additional drills will be mobilized onto the property to begin a large and systematic exploration program on the North Zone.

"Castle's drilling success in 2011 and the subsequent NI 43-101 resource estimate clearly shows there remains significant copper mineralization in the South Zone," said Mr. Mike Sylvestre, President & CEO of Castle Resources Inc. "We are getting an early start on South Zone to test this assumption and look forward to growing the South Zone inferred footprint in our next resource estimate."

The Granduc South Zone is a large extension of the high grade copper resource that Castle is currently in the process of developing beneath the historic Newmont and Esso mine workings. In 2011, Castle's drilling confirmed Granduc copper mineralization extends at least 600 meters to the south of Main Zone mineralization, and importantly, assay results from South Zone drill holes reported wider mineralized thicknesses and higher copper grades.
