CAP Castle Peak Mining Ltd

Castle Peak Mining Ltd. ('Castle Peak' or the 'Company') (TSX VENTURE: CAP) is pleased to report results for additional diamond drill holes completed on the Nkwanta concession and the initial drill test on the large Asuogya-Ayiem anomalous trend at the Company's Akorade project in the southern Ashanti belt in Ghana, West Africa. The additional holes on Nkwanta have returned encouraging values from limited shallow testing of the Apankrah target; including 3.0 metres ('m') of 1.2 grams per ton ('g/t') gold ('Au') from hole NKDDH009 and 5.0m of 1.4 g/t Au including 1.0m of 6.0 g/t Au from hole NKDDH011. In addition, hole ASUDDH001 on the Asuogya-Ayiem trend has returned 13.0m of 1.0 g/t Au from the initial testing of the AA Veins target.

These drill results represent the continuing initial testing stage 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 and continues with a total of 21 holes completed to date; 10 of 15 holes from Nkwanta, and one of six holes from Asuogya-Ayiem have now been reported with more assays 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 (see plan map Figure 1 at http://www.castlepeakmining.com/i/pdf/July182011_NR.pdf). As part of this systematic approach, the Company is currently awaiting the geophysical interpretation on the 3,425 kilometre VTEM/magnetic/radiometric airborne geophysical survey completed in June. This third-party interpretation is expected in mid-August, and will enhance target generation and compilation by providing an initial interpretation of the underlying geology and structure of this key land position in the southern Ashanti gold belt. This will be the first modern compilation of the geology at a concession and prospect level for this highly prospective land package.

Nkwanta

The Nkwanta area is highlighted by a 2,000m x 400m soil anomaly defined by gold values greater than 30 parts per billion ('ppb'). Two initial target areas defined by artisanal workings include the Apankrah and Nana structures which are east-north-east trending structures approximately 1000m apart in the northern portion of the soil anomaly (see plan map Figure 2 http://www.castlepeakmining.com/i/pdf/July182011_NR.pdf).

Apankrah Target

A total of seven core holes have been completed for a total of 754m evaluating approximately 225m of strike and approx. 100m of elevation on 50m fences in an area of abundant historical artisanal workings. Six additional holes are reported in this release testing the structure first reported on June 6, 2011, with the intercept of 7.5m of 7.2 g/t Au in hole NKDDH010. The drill results display multiple, continuous auriferous structures as indicated by continuous assays of greater than 0.03 g/t Au down hole and as haloes to logged structures with higher assay values. Highlights from the six drill holes are displayed in the following table.

Nana Target

A total of eight core holes have been completed for a total of 960m evaluating approximately 450m of strike and approx. 100m of elevation on 100m fences in an area of abundant historical artisanal workings. Assays are pending for the majority of these drill holes and will be reported once received and reviewed.

Asuogya-Ayiem

The Asuogya-Ayiem area is highlighted by a 9,500m x 1,000m soil anomaly defined by gold values greater than 30 ppb. Two initial target areas have been identified based on historical mapping, artisanal workings and preliminary geophysical results: the AA Veins target and the AA Central target both located on the central, western edge of the anomaly (see plan map Figure 1 at http://www.castlepeakmining.com/i/pdf/July182011_NR.pdf).

AA Veins Target

A total of six holes have been completed to date with two holes abandoned due to ground conditions for a total of 787m. The holes are testing a greater than 100m trend of meter-scale quartz vein blocks appearing to represent two separate parallel veins located approximately 15-20m apart. These veins have been the focus of continuous artisanal workings in the area. The initial holes are testing 150m of strike at shallow depths on 50m drill sections with additional holes stepping out on 100m sections and evaluating for additional parallel vein structures. Highlights of the initial drill hole are presented in the following table. Please refer to the Projects section at www.castlepeakmining.com to view complete table of drill results.

Technical Disclosure

Castle Peak's technical disclosure in this news release has been reviewed and approved by Darren Lindsay, P.Geo., Castle Peak's President and CEO, who serves as a Qualified Person under the definition in National Instrument 43-101 ('NI 43-101'). Mr. Joe Amanor and Mr. John Coates of SEMS Exploration Services Ltd. in Accra, Ghana have reviewed and approved the technical information in this news release and serve as Qualified Persons for the Castle Peak exploration program. The quality assurance and quality control procedures are being established by Mr. Coates of SEMS Exploration Services. The procedures include the systematic insertion of blanks, standards and duplicates into the sample stream either in the field or at the lab; samples are placed in sealed bags and are delivered to SGS Laboratory Services GH Ltd. in Tarkwa, Ghana, for routine gold analysis by 50g charge fire assay with atomic absorption finish. The Akorade project is an early stage exploration project and does not contain any mineral resources as defined by NI 43-101. The potential quantities and grades disclosed herein are conceptual in nature and there has been insufficient exploration to define a mineral resource for the targets disclosed herein. It is uncertain if further exploration will result in these targets being delineated as a mineral resource. Further information is available in the NI 43-101 compliant technical report dated February 14, 2011 and entitled "NI 43-101 Technical Evaluation Report on Nkwanta & Ayiem Concessions, Wassa-West District, Republic of Ghana, West Africa", a copy of which is filed under the Company's profile on SEDAR at www.sedar.com.
