Frontier Completes Acquisition of South Benkala

Frontier Mining Ltd (AIM: FML), the AIM quoted copper exploration and development company focused on Kazakhstan, is pleased to announce it has completed the acquisition of South Benkala, previously announced on 9 May 2011.

KazCopper LLP, Frontier's wholly owned subsidiary through which it holds the Benkala license, has received final approval from both the Ministry of Industry and Trade of Kazakhstan and the Inter-Ministerial Committees, enabling the Company to complete the purchase and transfer of the Subsurface Use Contract for the South Benkala mineral deposit from PromSnab2030 LLP to KazCopper LLP. Now that the amendments to the Subsurface Use Contract have been approved and the consideration of $2.5 million paid, the purchase is now complete.

The South Benkala Copper Project is located approximately 10 kilometres south of Frontier's existing Benkala license area. The Company will incorporate the South Benkala Copper reserve into its current Benkala project development to either extend the life of the SX-EW plant, currently under construction at Benkala, from seven to 11 years, or to use South Benkala oxide resources to expand production capacity at the Benkala SX/EW plant from 20,000 to 30,000 tonnes of cathode copper per year.

KazCopper LLP has already commenced its infill drilling program with two drills having been mobilised to the site to further define the oxide resource of the deposit.

As previously disclosed to the market, a GKZ resource estimation was developed by Soviet geologists in 1979 using drilling data from a 1978-79 drilling campaign which showed:
