CAP Castle Peak Mining Ltd

Castle Peak Mining Ltd. ('Castle Peak' or the 'Company') (TSX VENTURE: CAP), is pleased to report results for the first diamond drill hole completed on the Nkwanta concession at the Company's Akorade project in the southern Ashanti belt in Ghana, West Africa. This first drill hole represents the initial stages in the systematic evaluation of high priority targets within the Company's strategic land position hosting kilometer scale, untested soil and auger anomalies. The Phase I drill campaign started in late April, with a total of nine holes completed to date and more assays still pending.

The 2011 Phase I exploration program is two-fold: i) evaluate high priority drill targets to advance to a Phase II definition stage, and ii) continue to generate high quality targets to fill the exploration pipeline. Currently a single core drill is undertaking a 7,500m Phase I drill program on initial drill ready targets on Nkwanta, Asuogya-Ayiem, and POW.

Apankrah Target

A total of six core holes have been completed for a total of 653 metres ('m') evaluating approximately 150m of strike on 50m fences in an area of abundant historical artisanal workings. This target is adjacent to a 2,000m x 400m soil anomaly defined by gold values greater than 30 parts per billion ('ppb') (see plan map Figure 1). Highlights of results from drill hole NKDD010 are displayed in the following table with all intersections occurring within a core length of 71.5m exhibiting gold values greater than or equal to 30ppb (see Apankrah cross section Figure 2). Please refer to the Projects section at www.castlepeakmining.com to view complete table of drill results.
