Operational Highlights

Kazakhstan

Updated Kazakh independent Resource Report estimates the gross unrisked recoverable mean prospective oil resources to be 1.23 billion barrels of oil plus 634 Bcf of natural gas
Aral Oil Terminal commenced operations, Phase 2 completed and awaiting final State approval
Two new gas supply contracts signed effectively doubling the price for 2013 
to USD65 (USD72.8 including VAT) per 1,000 cubic metres (previously USD32.5 including VAT for the Kyzyloi and Akkulka Fields)
Akkulka Exploration Contract term extended to March 2015
Kul-Bas Exploration and Production Contract term extended to November 2015 (subject to usual contract amendments)

Tajikistan

Signed Farm Out Agreement ("FOA") for the Bokhtar Production Sharing Contract ("PSC") with subsidiaries of Total S.A. ("Total") and the China National Oil and Gas Exploration and Development Corporation ("CNODC")
Updated Tajik independent Resource Report estimates gross unrisked mean recoverable resources to be 27.5 billion boe
Completed acquisition of 501 km of new seismic data

Uzbekistan

Signed Production Enhancement Contract for a new oil field, the Chegara Group of Fields, in Uzbekistan
Signed MOU to provide the framework for a Joint Study and the negotiation process for an Exploration Agreement relating to certain exploration blocks in the North Ustyurt Basin of Uzbekistan - the same basin which contains the Doris oil discovery

Operational Update

Tajikistan

It is expected that the FOA for the Company’s Tajik assets will be completed in Q2 2013. The Tajik Government has approved the participation of subsidiaries of Total and CNPC in the Bokhtar Production Sharing Contract and remaining points are now being finalized. All three parties are working hard jointly to achieve closing as soon as possible.

As part of the transaction, the new Joint Operating Company will present a comprehensive work programme upon completion of the FOA for the remainder of 2013.

Kazakhstan

In Kazakhstan in 2013, the Company plans to drill up to three wells targeting oil on the Akkulka Exploration Contract area.

The first well is firm and is expected to commence drilling in June 2013 and will target the Doto prospect nearby to the Doris oil discovery. This well has a relatively low risk in the exploration portfolio and is targeting mean unrisked prospective recoverable resources of 21.6 MMbbls (Gustavson Associates) in the Cretaceous and Upper Jurassic.

Following the increase in gas price in early 2013, further work will be carried out to increase production including workovers on the AKK05 and AKK14 wells in Q2 which will be tied in to the gas pipeline thereafter. A further programme will follow to include tie-in of additional wells and the drilling of further shallow gas exploration prospects in the area which are clearly defined on the seismic data as strong amplitude anomalies.

It is planned to test (including acidisation) the previously drilled KBD01 (“Kalypso”) well, which contains a 100 metre (328 feet) gross section in Permo-Carboniferous limestones which is interpreted to contain moveable hydrocarbons based on wireline logs and mud log data. It is also planned to acquire additional seismic this year on the Kul-Bas and Akkulka Contract Areas.

The activities planned in Kazakhstan as described above are contingent on availability of funding, and the Company will provide a more detailed capital programme breakdown on closing of the Tajikistan farm-out, which is expected in Q2.

Tethys is focused on oil and gas exploration and production activities in Central Asia with activities currently in the Republics of Kazakhstan, Tajikistan and Uzbekistan. This highly prolific oil and gas area is rapidly developing and Tethys believes that significant potential exists in both exploration and in discovered deposits.

Cautionary Statements:

This press release contains “forward-looking information” which may include, but is not limited to, statements with respect to our operations, completion of the FAO and drilling, testing and well workover programmes for 2013. Such forward-looking statements reflect our current views with respect to future events and are subject to certain risks, uncertainties and assumptions, including the risk that completion of the FOA will be delayed beyond Q2 and the risk of changes in our drilling, testing and well workover programmes. See our Annual Information Form for the year ended December 31, 2012 for a description of risks and uncertainties relevant to our business, including our exploration activities. A barrel of oil equivalent (“boe”) conversion ratio of 6,000 cubic feet (169.9 cubic metres) of natural gas = 1 barrel of oil has been used and is based on the standard energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

The references in this press release to “prospective resources” means those quantities of petroleum estimated, as of June 30, 2012, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective resources have both an associated chance of discovery and a chance of development. There is no certainty that any portion of these resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of these resources.

The resources estimates contained or referred to are estimates only and are not meant to provide a determination as to the volume or value of hydrocarbons attributable to the Company’s properties. There are numerous uncertainties inherent in estimating quantities of resources and cash flows that may be derived, including many factors that are beyond the control of the Company. The following is a non-exhaustive list of factors which may have a significant impact on the above estimates of prospective resources: despite the classification that they are as yet undiscovered but may be potentially recoverable the Company may be unable to carry out the development or their potential recovery; the activity may not be economically viable; the Company may not have sufficient capital or time to develop them; there may be no market or transportation routes for the production; legal, contractual, environmental and governmental concerns might not allow for the recovery being undertaken; reservoir characteristics might prevent recovery. The recovery of the resources is subject to the following risks and uncertainties: market fluctuations, the proximity and capacity of oil and gas pipelines and processing equipment, government regulation, political issues, export issues, competing suppliers, operational issues (exploration, production, pricing, marketing and transportation), extensive controls and regulations imposed by various levels of government, lack of capital or income, the ability to drill productive wells at acceptable costs, the uncertainty of drilling operations, factors such as delays, accidents, adverse weather conditions, and the availability of drilling rigs and the delivery of equipment.

Non GAAP Measures:

This press release includes references to Non GAAP measures, including ” cash profit” and “cash loss.” These terms do not have any standardized meaning under IFRS. Cash profit (cash loss) is also referred to as profit (loss) before non-cash items in the Management Discussion & Analysis for the year ended December 31, 2012 and is defined as revenue less production costs, administrative costs, listing expenses, business development expenses and foreign exchange. See page 11 to the Management Discussion & Analysis for the year ended December 31, 2012 for a reconciliation of these amounts to IFRS measures.

(1) These terms are Non-GAAP measures. See “Non-GAAP Measures” above.

(2) “1P” means Proved Reserves; “2P” means Proved plus Probable Reserves and “3P” means Proved plus Probable plus Possible Reserves.
