"I would like to invite investors and shareholders to participate in our review of the initial Granduc NI 43-101 resource estimate," stated Mike Sylvestre, President & COO of Castle Resources. "This significant new resource estimate identifies a high grade copper zone between the 2600 and 1600 foot levels of the main zone and to the north along strike, referred to as the 'North Zone' Importantly, it does not include any of the downdip targets beneath the 1600 foot horizon identified as a historical resource in our initial assessment prior to drilling last fall, a potential zone of contiguous mineralization we will be aggressively exploring this year."

Investors are encouraged to reference the Castle press release dated February 28 titled 'Castle Resources NI 43-101 Resource Estimate For Granduc Copper Project Exceeds Expectations'. In addition, an updated corporate presentation will be available on the Castle website should investors want further information and this will include new images and schematics of the Granduc resource and exploration upside.

Granduc Highlights:

  • SRK Consultants provided the following NI 43-101 compliant resource estimate using a 0.8% Cu cut-off grade: Indicated Resources of 3.75 million tonnes grading 1.59% Cu containing 130.4 million pounds of copper; Inferred Resources of 15.8 million tonnes grading 1.36% containing 471.5 million pounds of copper
  • Exploration Potential is estimated to contain an additional 17 to 23 million tonnes grading between 1.3% Cu to 1.6% Cu. The potential quantity and grade of the exploration potential is conceptual in nature and there has been insufficient exploration to define a mineral resource. It is uncertain if further exploration will result in the exploration targets being delineated as a mineral resource
  • 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 within 4 km 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, 1,700,000 incentive stock options (the "Options") to officers, management, directors and consultants of the Company. The Options will be exercisable for a five year period at $0.75 per share.
