TORONTO, ONTARIO--(Marketwire - June 7, 2011) - Castle Resources Inc. (News - Market indicators) ("Castle" or the "Company") is pleased to announce that it has initiated comprehensive environmental studies at its Granduc Copper Project located near Stewart, B.C.

"As part of our overall redevelopment strategy at the Granduc Copper Project we have begun comprehensive baseline environmental data collection," stated Mr. Mike Sylvestre, President & COO of Castle Resources. "These baseline studies will focus on geochemistry, water quality, hydrology, hydrogeology, fisheries and aquatic biota, vegetation, wildlife, social, economic, and heritage topics, to name a few. We are moving quickly to initiate these detailed studies in preparation for the permitting process."

Working with Smithers based Ecos Environmental Consulting Inc., Castle Resources has assembled a team of highly rated technical specialists with proven track records for all necessary environmental disciplines. Specifically, Castle has engaged SRK Consulting (Canada) Inc. for ML/ARD and hydrogeology studies; Lorax Environmental Services Ltd. for water quality and hydrology; Triton Environmental Consultants Ltd. for fisheries and aquatics; and is finalizing arrangements for Stantec to conduct terrain, soil, vegetation, wildlife, air quality, meteorology, archaeology, health and other studies that will be required, and to provide additional project management and team support as needed. These baseline studies are the first step of a comprehensive environmental process as Castle advances the Granduc Copper Project towards feasibility and ultimately production. 

Granduc Highlights:

• 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; 17 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 on a 54 km 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 along a 4+ km trend, with the main Granduc orebody centrally located within the trend
