Castle has now completed over 12 holes of its expansion drilling program and aims to complete the surface program at the Granduc by September. There are currently 4 drills turning at site with a strategy of a) completing the drilling on the South Zone begun in 2011, an area of robust mineralization that has extended the strike of the current resource by over 600 meters to the south of the historic Granduc orebody, and b) defining the potential copper mineralization of the North Zone identified by SRK Consulting as 'exploration potential' (see SEDAR technical report dated April 9, 2012).

Brad Leonard, P. Geo., Castle's Exploration Manager, is the Qualified Person responsible for the scientific and technical work (as defined under National Instrument 43-101) discussed in this press release, and has reviewed this press release. Castle implemented a QA/QC protocol for all its exploration and diamond drilling program on the Granduc.
