("Frontera" or the "Company")

Houston, Texas, U.S.A. - 31 July 2012

BUSINESS UPDATE

Frontera Resources Corporation (London Stock Exchange, AIM Market, FRR), the oil and gas exploration and production company with assets in the country of Georgia, today announces an update:

Georgia Block 12:

- Three rigs and two swabbing units are currently in operation at Mirzaani Field, Mtsare Khevi Field and Taribani Field to maintain and enhance current production levels. In July, daily oil production has averaged approximately 220 bbls per day, including a new daily high for the year of 300 bbls per day.

- Mtsare Khevi Field Gas Sales: Commencement of gas sales from the Mtsare Khevi Gas Complex, which is projected to commence at a rate of 2 million cubic feet per day during Q3, has been delayed from July due to unanticipated delays associated with final issuance of certain requisite permits relating to transportation of the gas from Georgian government authorities. The Company now anticipates that gas sales will commence in September.

- Taribani Field: Preparation is underway at Taribani Field for commencement of a 4 well drilling campaign designed to increase oil production this year. The Company is continuing its negotiations with strategic financing partners with the aim of commencing drilling operations during Q4 2012.

Corporate:

- Corporate Finance: A nominal draw down in the amount of £145,068 ($225,000) on its previously announced $35 million Standby Equity Distribution Agreement ("SEDA") with YA Global Master SPV Ltd. has been made for the purpose of providing the Company with a short term buffer associated with the infrastructure project in advance of impending commencement of the gas sales from the Mtsare Khevi Gas Complex referred to above. The draw down has been undertaken at a price of 0.51660 pence per ordinary share of $0.00004 in the capital of the Company ("Ordinary Shares") in accordance with the terms of the SEDA, and will result in the issue of 28,081,300 new Ordinary Shares ("New Ordinary Shares").

Application has been made for the New Ordinary Shares to be admitted to trading on AIM, which is anticipated to occur on 6 August 2012 ("Admission"). On Admission the New Ordinary Shares will rank pari passu with the Company's existing issued Ordinary Shares.

For the purpose of the Financial Services Authority's Disclosure and Transparency Rules (the "DTRs"), the Company notifies the market that following Admission, the Company's issued share capital will consist of 2,173,559,646 Ordinary Shares, with voting rights. The Company does not hold any Ordinary Shares in treasury.

The above figure of 2,173,559,646 Ordinary Shares may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the DTRs.
