Castle Resources to Rehabilitate 17 km Tunnel at its Granduc Mine, British Columbia

- Haulage Tunnel Connects the Minesite to Millsite and Enables Year Round Underground Drilling Access

- 32,000 Metre Surface Drill Program to Commence June 1st; Robust Underground Drilling Program to Commence Fall 2011 Upon Completion of Tunnel Rehabilitation

- Procon Mining Contracted: Highly Respected in the Mining Industry, with an Impressive Performance Record in Both Safety and Operations

TORONTO, ONTARIO--(Marketwire - May 26, 2011) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company") is pleased to announce Procon Mining Partnership has been contracted to rehabilitate the 17 km Tide Tunnel at its Granduc Mine, British Columbia, beginning June 2011 with a proposed completion target of fall 2011.

The Tide Tunnel connects the historic Granduc mine and mill site to a 51 km long road which leads directly to a year round deep sea terminal in Stewart B.C. Rehabilitation of this tunnel will facilitate a more aggressive year round drilling strategy as Castle seeks to prove up a significant copper resource and ultimately bring the Granduc mine back into production.

Procon will begin to mobilize equipment, material and manpower and will be onsite in the coming weeks. Procon's mandate is to re-establish tunnel ventilation, install bolts, mesh and shotecrete as required, determine quality of existing steel sets and replace where necessary, and prepare the tunnel for the efficient movement of men and equipment. In addition, Procon will be rehabilitating select areas of the mine workings in preparation for the underground drill program.

"The rehab of the Tide Tunnel is a key step forward for Castle Resources," said Mr. Mike Sylvestre, President & COO. "Not only will it permit year round underground access to drill stations but as well it will provide pre-development access and intelligence on the mine infrastructure which will be critical to the restart of the mine."

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
