Yerlan Aliyev, Chairman and Chief Executive of the Company said:

"Since commencing production in 2013, both management and operational team is working hard and carrying out trials and tests to find the optimal working parameters at Benkala. We have an understanding that the resource size, type of ore, available utilities and infrastructure we put in place enable us to reach required levels of production.

"Baitemir continues to offer significant potential that allows the management to be confident about the future of the company. We were highly encouraged by the findings of an Independent Expert Report, which we commissioned during the first half and published results from in mid July.

"Like any production company going through a commissioning phase, we face challenges such as cash flow, often incredibly hostile environmental conditions, geographical remoteness and unproven equipment.

"The qualification of the team and support of our partners equip us well to meet these challenges, and drive this company towards becoming an established copper producer in the region, achieving long lasting profitability."

Chairman and Chief Executive's Statement

I am pleased to report the first half of 2013 delivered significant operational and corporate progress.

Following a harsh winter customary for the region, we were able to restart production in April and have been working hard on finding optimal parameters for stable operations at Benkala. The first shipments of copper began on schedule in the first week of June and by 30 June we had shipped 390 tonnes of copper cathode. Since commissioning in August of 2012, the Benkala SX-EW plant has produced more than 1,000 tonnes of LME Grade A copper-cathode and shipped and sold approximately 953 tonnes to date. During the period under review, we undertook a series of enhancement and expansion activities across Benkala, which included construction work on an additional four leach pads, which will bring the total number of leach pads up to six.

Similarly, post the period end in July, we announced the purchase of an additional agglomerator. This agglomerator will enable the Company to achieve higher quality agglomeration, while increasing throughput, by introducing an additional agglomeration step. At the same time, the expected assembly scheme will provide a reserve line for agglomerate production and will ensure stable operation of the crushing and agglomeration complex.

As stakeholders will have seen, we hired Adam Moroney, who is an independent degree-qualified consultant with 20 years of SX/EW management and heap leach research experience. He has reported his findings from Benkala this month and overseen the above mentioned enhancements at Benkala. As a result of cooperation of our operational team with Mr. Moroney, we were able to incrementally increase the current leach pad stacking height of 2.5 meters to 3.5 meters, and then on to 4.2 meters and 6 meters, which was recently completed. The full details of Mr Moroney's assessment, recently released to the market, can be found on the Company's website.

Further technological studies and exploration were undertaken at Baitemir across the latter half of the six months, incorporating drilling, trenching and geophysics, so that the Company could gain further understanding of the resource. Based on historical data provided by our geology team, Wardell Armstrong published non JORC compliant report of review and preliminary valuation of Baitemir. In their report, Wardell Armstrong also undertook an assessment of the Beschoku and Yubileiny deposits to further determine their potential as a satellite feeder for proposed facilities at Baitemir, the results of which were published post period end.

Wardell Armstrong, estimate Baitemir-Beschoku has a Post Tax NPV of $52.7m taking a discount rate of 10%

Corporate

In March, we announced we had increased our Sberbank debt facility by $17.9 million and extended the term until October 2018. Sberbank has provided Frontier with loan facilities since 2011. The additional loan brings the total amount of existing Sberbank facilities to US$52.9 million.

I would like to announce that in addition to our London quote, we intend to apply for the Company's shares to be listed on the Kazak Stock Exchange in order to satisfy the demands of the regulatory requirements in Kazakhstan.

Outlook

We have a large resource, low acid-consuming ore, readily-available and developed utilities and an actively competitive pool of raw materials suppliers.

In terms of Baitemir, the project offers significant potential, which allows us to look into future with confidence, and we will be updating the public with new information as our studies and exploration progress.

Like any production company going through a commissioning phase, we face challenges such as cash flow, at times incredibly hostile environmental conditions and unproven equipment.

Nevertheless, I remain confident the qualification of the team and support of our partners equip us well to meet these challenges, and drive this company towards becoming an established copper producer in the region, achieving long lasting profitability.
