Notes to Editors

About Frontier Mining Ltd:

Frontier Mining Ltd. is a mineral exploration and development Company that is incorporated in the Cayman Islands for the purpose of exploring and developing gold and copper deposits in the Republic of Kazakhstan. Through its subsidiaries and affiliates, Frontier locates, evaluates, acquires, explores and develops mineral properties.

Frontier currently owns two licenses in Kazakhstan. They are the Naimanjal exploration and mining licence, held by FML Kazakhstan, and U.S. Megatech BVI which holds the Benkala licence, via KazCopper LLP. FML Kazakhstan is a wholly-owned subsidiary of Frontier Mining Ltd.

In Kazakhstan, Frontier has one producing gold mine, Koskuduk; and the Benkala copper mine, currently under development with initial production planned in 2011.

A Competent Persons Report ("CPR") completed by Wardell Armstrong International ("WAI") in June 2010, estimated the oxide section of the Benkala project, which represents development of only ~10% of the total resource at Benkala, to have a NPV of $190 million, based on 0.5% diluted copper grade, 63% recovery and 185,000 tons of contained metal at a 6,000 USD per tonne copper price. Frontier will use the production platform of the SX-EW project to finance further evaluation and technical studies required to advance development of the significant Benkala sulphide resource.

Frontier also has a potential copper porphyry deposit with associated gold and molybdenum, Baitimir; and several copper/gold prospects along a 25-km trend including both VMS and porphyry types. Metallurgical tests on its Beschoku and Yubileiny copper projects confirm the oxide copper ore is amenable to extraction using low cost SX-EW technology.

Frontier maintains an administrative and technical office in Almaty, the former capital city of Kazakhstan and the main business centre in the southeast. The Company also maintains offices in Semipalatinsk and Aktyubinsk, close to the Naimanjal and Benkala operations respectively.
