AGM Update

Frontier Mining Ltd (AIM: FML), the AIM quoted Kazakhstan copper and gold exploration and development company, announces that the Group's Annual General Meeting is being held today at Almaty. Ahead of the meeting the Company is giving the following update.

2011 has seen a number of significant milestones in the Company's development including:

·; In April, following receipt of the necessary regulatory consents, the formal completion of the acquisition of the remaining 50% of the Benkala Copper project not previously owned by the Company and the Maminskoye gold deposit in Russia

·; In May, the acquisition of the South Benkala Copper project, significantly adding to Frontier's copper resource in the Benkala region

·; In July, the sale of the Maminskoye gold deposit in Russia for $37.5m in cash

·; The securing of full funding required to complete the construction of the SX-EW plant at Benkala. This was achieved through the sale of the Maminskoye gold deposit and after taking into account other financing facilities available to the Company

·; Significant progress being made in the commissioning of the Benkala SX-EW plant with crushing expected to commence in October and copper production before the end of the current financial year.

·; Further progress in the preparation of the Bankable Feasibility Study for the Benkala project which is expected to be published shortly

·; Continued progress at the other Frontier operations at Koskuduk and Baitemir. At Baitimir the Company has commenced a 6,000 meter drilling program to further define the mineral inventory, anticipating the generation of a JORC compliant resource in 2012

Erlan Sagadiev, CEO of Frontier Mining, commented: "We are pleased with the continued progress at Benkala. All equipment is now on site and we are confident that Frontier will be producing copper before the end of the year. Frontier is in a strong financial position and we fully anticipate moving the Company forward to the next stage in its development."

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.
