CAP Castle Peak Mining Ltd

Castle Peak Mining Ltd. ("Castle Peak" or "the Company") (TSX VENTURE: CAP), is pleased to announce it has commenced a 3,425 kilometre airborne survey program (VTEM, magnetics, radiometrics) over the Company's entire land package in the southern Ashanti belt in Ghana. The survey kicks off the $4 million exploration program announced on March 21, 2011, which will include a 15,000 metre ('m') Phase I drill program. The aggressive exploration program will also include the continued consolidation of the overall land package and the refinement of soil anomalies, through the collection of 10,000 auger and trench samples, into drill ready targets on the Ayiem, POW and Kedadwen properties.

Castle Peak's strategic land holdings in the southern Ashanti belt are host to gold in soil anomalies that range in strike from 200m to over 5,000m and range in width from 100m to 500m. These anomalies are defined by gold ('Au') values in excess of 50 parts per billion ('ppb') but values contained within the trends vary from less than 20ppb to greater than 8000ppb Au. The airborne survey currently underway has been contracted to Geotech Airborne Ltd., and will assist in defining the structural framework hosting the numerous auriferous trends identified in the soil surveys. The initial field crews are now in place undertaking auger drilling on high priority soil anomalies in order to refine drill targets.

In addition, a final 43-101 technical report on the POW property prepared by SEMS Exploration has validated previous trench sample results from two trenches that were resampled. Previous sampling of DT5 crossing a silicified zone at a contact of metavolcanic rocks and granitoid rocks returned 18m of 0.99 g/t Au; a 14m subsection of this contact zone was resampled by SEMS with the resampling returning 14m of 0.97 g/t Au (previous sampling of the same interval returned 14m of 0.92 g/t Au). A resampled silicified section of trench DT8 returned eleven samples averaging 0.88 g/t Au (ranging from 0.07 to 1.51 g/t Au) which compared favourably to the previous sampling of the same section of eleven samples averaging 0.97 g/t Au (ranging from 0.09 to 1.85 g/t Au).

"Our goal is to ultimately define near-surface gold resources across our land holdings," stated Darren Lindsay, Castle Peak's President and CEO. "Through geological compilation and systematic exploration, regional gold anomalies will be refined to the target evaluation stage; once prioritized they will be aggressively tested in order to rapidly evaluate resource potential."
