Castle Peak Granted Netas Assignment from Ghana Ministry; Adds Enyinase Concession to Overall Land Package

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/18/11 -- Castle Peak Mining Ltd. ('Castle Peak' or 'the Company') (TSX VENTURE: CAP) is pleased to announce that Hon. Mike Hammah (MP), Minister of Lands and Natural Resources of the Republic of Ghana, has granted his consent of the Deeds of Assignment ('the Assignment') for the assignment of the Nkwanta and Asuogya prospecting licenses from Netas Mining Company Limited ('the Vendor') to Castle Peak's wholly owned subsidiary Canterbury Mining Company Limited. Terms of the Assignment for the Nkwanta (18.5 square km) and the Asuogya (26.75 square km) licenses are for a 95% interest in both licenses, and required an initial payment of US$100,000 on signing of the agreements, followed by a final payment of US$1,200,000 which is now being processed following the consent of the Assignment by the Minister. The Vendor retains a 5% free carried interest in each license.

Castle Peak has also entered into an assignment agreement with Satemkon Mining (GH) Ltd. for 100% of the Enyinase prospecting license (agreement includes a three year due diligence period). The Enyinase license covers 36.5 square kilometres immediately west of Castle Peak's core land package, and is contiguous with the pending Great Yorkshire prospecting license. This license covers an interpreted splay of the Salman Structure currently being evaluated and exploited by Adamus Resources Limited operating to the southwest of Castle Peak's land package. The terms of the agreement are as follows: US$40,000 paid upon signing of agreement; US$60,000 paid on the first anniversary; US$80,000 paid on the second anniversary; US$120,000 paid on the third anniversary; and final payment of US$250,000 paid on consent of assignment of the license to Castle Peak by the Minister of Lands and Natural Resources with the Vendor retaining a 2% net smelter royalty.

Castle Peak's strategic land holdings in the southern Ashanti belt are host to gold in soil anomalies that range in strike from 200 metres ('m') 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. One of the strongest anomalies, roughly 1200m by 350m of greater than 70ppb Au, occurs on the Nkwanta license. The largest anomaly occurs on the Asuogya and Ayiem licenses and is 9,000m long and 1,000m wide. Auger drilling to further refine this anomaly is underway with proposals to follow up all significant anomalies with trenching or core drilling.
