Castle Resources Intersects 3.17% Copper Over 8 Meters at Depth at Granduc Copper Project

- GD11-16 Intersects High-Grade VMS Lens at Depth Confirming Significant Mineralization Occurs 600 Meters Below Historic Mining Zones

- Recent Assays Continue to Demonstrate Widespread Copper, Gold and Silver Mineralization at the Granduc


TORONTO, ONTARIO--(Marketwire - Sept. 8, 2011) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company") is pleased to announce its second positive set of drill assay results from the ongoing 35,000 meter surface exploration program at the Granduc Copper Project located near Stewart, B.C.

"Drill assays continue to identify high-grade copper mineralization along the combined Main and South Zone strike," stated Mr. Mike Sylvestre, President & CEO of Castle Resources. "In particular, we are very impressed with the results of GD11-16 which confirms historical assumptions that high grade copper mineralization occurs down to sea level, over 600 meters below historic production zones. This deep hole is important as it clearly reveals Granduc mineralization is open at depth and increasing in grade."

Highlight:

Hole Start (m) End (m) Width (m) % Cu Au (g/t) Ag (g/t) %Fe
GD11-16 682 690 8 3.17 0.37 7.50 11.98
inc 686 690 4 5.40 0.65 13.00 16.40

Hole GD11-16 successfully tested the deeper portion of the Main Zone mineralization approximately 100 to 200 m above sea level. The high grade intersection appears to be the highest grade and the deepest intersect of the program to date and confirms that the Main Zone mineralization may be further encountered at elevations at sea level or below. All assay results to date continue to demonstrate high grade copper mineralization downdip of the historic Main Zone production zones and along strike on the South Zone (see attached location map). Castle has completed over 50 holes of its 60+ hole step out and expansion drilling program and aims to complete the surface program at the Granduc by the end of September.
