Castle Peak Intersects 6m of 80 g/t Gold, Uncut, at the Apankrah Target; Including 1.6m of 296 g/t Gold
Vancouver, B.C., August 22, 2012 - Castle Peak Mining Ltd. ('Castle Peak' or the 'Company', TSX.V: CAP), is pleased to report results for additional diamond drill holes completed at the high grade Apankrah target at the Company's Akorade Project in the southern Ashanti belt in Ghana, West Africa. Drill hole NKDDH022, a down plunge test of the Apankrah Shoot returned, uncut, 80 grams per tonne ('g/t') gold ('Au') across the 6.0 metre ('m') mineralized structural zone within a 17m intersection of lower grade gold mineralization. The Apankrah target is located 15km west of the Mpohor deposits (Golden Star Resources Ltd.), approximately 30km east of the Nzema Mine (Endeavour Mining Corp.) and 25km south of the Iduapriem Mine (Anglogold-Ashanti Ltd.).
Drill hole NKDDH022 was drilled 50m down-plunge of the initial intercepts in the Apankrah Shoot (NKDDH010 and NKDDH016 which returned 7.5m of 7.23 g/t Au and 4.0m of 12.47 g/t Au respectively). The second hole reported from the Apankrah structure, NKDDH023, is located 200m along strike to the east of the Apankrah Shoot; an area interpreted to host the potential for a second shoot in the structural zone. This hole returned 13m of 0.22 g/t Au indicating the structural zone is mineralized with the expected veining and alteration assemblage, however, stronger grades were not present. (See Plan map Figure 1 for hole locations).
Additionally, two holes evaluating a conceptual shoot on the parallel Nana structure, located 500m north of Apankrah, returned 0.5m of 10.3 g/t Au (NKDDH020) at a sheared contact of a porphyry dyke in the metavolcanic package. The dyke intersection was unexpected and the geological interpretation in this area continues in order to determine high potential targets.
Darren Lindsay, President and CEO, stated "Castle Peak is pleased to be demonstrating exploration potential, with a shallow higher grade target such as Apankrah, in what we consider to be an overlooked portion of the Ashanti Gold Belt. These results continue to provide encouragement for additional high grade potential in the Apankrah target area in general. And, given the coarse nature of the gold observed, we are modeling the various veins and inferred controlling structures in order to determine additional upside by increasing the drilling density and additional target evaluation."
The initial follow up and target evaluation program of 3,030m is now complete, with 8 of the 14 holes reported. The current drill results represent the continuing evaluation of the higher grade gold distribution in the Apankrah target area, in particular the Apankrah structure, one of a series of parallel east-north-east ('ENE') trending structures across the Nkwanta Concession. Road building delays continue to stall access to the Dansuom Sheer target; meanwhile, field teams are following up on the new road exposures, mapping and sampling, in support of further developing the conceptual POW SVI target in the Dansuom area.
Summary Table of Drill Results:
|Hole ID||Target||From (m)||To (m)||Length (m)||Au (g/t)||Notes|
|NKDDH021||Nana||100.0||105.0||5.0||0.10||Cut off 0.05g/t to observe halo|
|and||115.0||125.0||10.0||0.07||Cut off 0.05g/t to observe halo|
|NKDDH022||Apankrah||193.0||199.0||6.0||79.9||50m step down plunge NKDDH016|
|NKDDH023||Apankrah||111.0||123.0||13.0||0.22||200m step east of NKDDH016|
- Lengths are core lengths; true widths are estimated between 75-90% of core length
- Composites are uncapped, length weighted averages with a cut off of 0.1 g/t Au and inclusive of up to 3m of assays below the cut off value unless otherwise noted.

The Nkwanta area is highlighted by a 2,000m x 400m soil anomaly defined by gold values greater than 30 parts per billion. Two initial target areas defined by artisanal workings include the Apankrah and Nana structures which are ENE trending structures approximately 500m apart in the northern portion of the soil anomaly (see Figure 1 Plan Map). A third parallel structure located north of the Nana target is active with artisanal mining. A geophysically anomalous trend and artisanal work area trending north-northeast between the known and inferred shoots is known as the Scorpio target.
A total of 9 core holes have been completed, with 6 being reported to date. This initial follow-up program has partially defined the geometry of the previously inferred higher grade shoot and drilling indicates that the shoot is open on strike at depth to the west, down dip and down plunge. The steeply plunging shoot will be evaluated down dip and down plunge based on knowledge gained from this drilling and discussions with artisanal miners on parallel structures. Drilling has tested to a vertical depth of approximately 200m and based on shoot geometry, the next proposed holes are to expand on strike and test target depths of up to 250m, as shoots on known productive structures in Ghana tend to improve at these depths.
A total of 2 core holes, 368m, have been reported in this campaign. Drilling evaluated an inferred shoot based on previous drill results and the geometry confirmed at the Apankrah target. The results indicate gold grades are controlled by the contacts of an altered porphyry dyke that has intruded the structural zone at this location.
A total of 3 core holes, 808m, have been completed on this target during this campaign; with geological work and sampling yet to be completed. Drilling evaluated a northerly-trending, coincident magnetics, resistivity and conductivity anomaly that appear to link the Nana and Apankrah structures. Artisanal mining is active along this target in shallow pits and small shafts.
The 2012 exploration program is two-fold: i) follow up on 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 including Phase I drill evaluation. As part of Castle Peak's systematic exploration approach and to assist in further targeting, the Company is currently awaiting the final geophysical interpretation and final data on the ground magnetics and induced polarization geophysical surveys completed on the Nkwanta, Asuogya-Ayiem and Great Yorkshire concessions in May. This third--party interpretation is expected in late August, and will enhance target generation and compilation by providing a more detailed interpretation of the underlying geology and structure of this high potential target area in the southern Ashanti gold belt.
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'). The exploration activities are supervised by Clive Arthur, Castle Peak's Vice President Exploration. The procedures include the systematic insertion of blanks, standards and duplicates into the sample stream both in the field and 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. Samples with visible gold or returning greater than 5 g/t Au from fire assay are subject to analysis using screen metallic assay. 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.
