CAP Castle Peak Mining Ltd

Castle Peak Mining Ltd. ('Castle Peak' or the 'Company') (TSX VENTURE: CAP), is pleased to report geochemical results from 1,978 auger samples taken from the Company's Akorade project in the southern Ashanti belt in Ghana, West Africa. Results represent approximately 80% of the samples collected to date. These samples have been collected to evaluate the next phase of drill targeting for the ongoing exploration program. Highlights include:

--  Sampling from the Kedadwen concession returned a 3,000 metre ('m') x
    250m east-northeast trending anomaly with two sub parallel anomalies in
    addition to intersecting north trending anomalies;
--  The Asuogya-Ayiem concessions returned numerous northerly trending
    anomalies that will require additional sampling on 50m x 10m spacing to
    further define mineralized trends;
--  Sampling on the Dompem concession defined a north-east trending anomaly
    (1,200m x 75m).

A total of 1,978 samples have been analyzed with 182 returning results greater than 50 parts per billion ('ppb) gold ('Au'). Overall results ranged from background (less than 10 ppb Au) to a high of 1,115 ppb Au or 1.11 grams per ton ('g/t') Au. Additional assay results are pending for additional samples on the Ayiem, Kedadwen and Dompem concessions.

Kedadwen Trends

To date, results from 528 of 544 samples collected on Kedadwen have been received, ranging from detection limit (10 ppb Au) to 1,115 ppb Au, with 65 samples or 12% returning greater than 50 ppb Au. The main Kedadwen auger anomaly is defined by an east-northeast trending greater than 50 ppb Au that has a strike extent of 3,000m and is 250m wide. A sub-parallel anomalous zone, limited by sampling, occurs approximately 600m south of the main anomaly. Three northerly trending anomalies occur within the sampled area and have varying strike extents of 400m to 1,200m. Two of these anomalies intersect the main anomaly (Figure 1).

Asuogya-Ayiem Trends

To date, results from 907 of 1,087 samples collected on Ayiem have been received, ranging from detection limit (10 ppb Au) to 1,060 ppb Au, with 46 samples or 5% returning greater than 50 ppb Au. Results have confirmed historic sampling trends to the north and north-northwest (Figure 2). Additional auger sampling on tighter line and sample spacing will be required to refine larger anomalous areas defined by gold assays returning greater than 20 ppb gold and trends defined by assays greater than 50 ppb Au.

Dompem Trends

To date, results from 543 of 769 samples collected on Dompem have been received, ranging from detection limit (10 ppb Au) to 430 ppb Au, with 71 samples or 13% returning greater than 50 ppb Au. The western-most anomaly is 1,200m x 75m, and is defined by a approximately 100 ppb Au anomaly within a 20 ppb anomaly. The eastern north-south anomaly is defined by a 100 ppb anomaly within a 30 ppb anomaly with a strike extent of 2300m and an average width of 150m (Figure 3).

Geophysics

In addition to the auger sampling, Castle Peak has now completed the previously announced 3,425 kilometre ('km') VTEM/magnetic/radiometric airborne geophysical survey over its entire approximately 200 square km land package. Data collection is complete, and preliminary interpretation is on-going. This survey 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.
