Revenues Increased by 106%

GRAND CAYMAN, CAYMAN ISLANDS, Mar 30, 2012 (MARKETWIRE via COMTEX) --Tethys Petroleum Limited ("Tethys" or the "Company") (TSX: TPL)(LSE: TPL) today announced its Annual Results for the period ended December 31, 2011. Tethys is focused on oil and gas exploration and production activities in Central Asia with activities currently in the Republics of Kazakhstan, Tajikistan, 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.

Operational Highlights

Kazakhstan

-- Successfully tested the Doris AKD05 and AKD06 appraisal wells with a combined flow rate of over 6,000 barrels of oil per day -- 2P Reserves increased by 45% to 25.3 million barrels of oil equivalent -- AKD03 (Dione) exploration well flowed commercial oil from a new reservoir -- KBD01 (Kalypso) exploration well drilled and logged with indications on the logs that moveable hydrocarbons are present. To be tested later this year -- Aral Oil Terminal land acquired and construction commenced (now complete and about to commence operations) 

Tajikistan

-- Deep sub-salt exploration programme advanced with completion of Graviometry Survey -- EOL09 (East Olimtoi) exploration well discovers oil, believed to be the first oil discovery in Tajikistan since independence - testing programme about to recommence -- Persea exploration well (the last commitment well under the Bokhtar PSC) completed with potential logged hydrocarbons - to be tested after EOL09 well -- Successful rehabilitation work on Beshtentak oilfield 

Uzbekistan

-- Negotiations commenced on acquiring a new producing oil field -- MOU signed to carry out exploration studies on a large acreage position in the North Ustyurt Basin - the same basin which contains the Doris oil discovery 

Financial Highlights

-- 2011 Total Revenue was USD30.30 million (2010 USD14.71 million) -- The average oil and gas production in the year ended 2011 was 5,730 barrels of oil equivalent per day. The average oil and gas production for Q4 2011 was 6,584 barrels of oil equivalent per day -- Tethys increased interest in the Bokhtar PSC to 85% (from 51%) -- Total assets year-end 2011 USD263.39 million (2010: USD267.75 million) -- Capital expenditure in 2011 was USD41.90 million -- 2011 Operating costs were USD10.78 million (2010: USD7.08 million) -- 2011 Net Loss of USD26.99 million (2010: USD29.65 million) -- Cash balance at December 31, 2011 of USD11.63 million 

The Company also announced completion of a USD10 million loan facility secured against its drilling rigs and related equipment. Part of this loan was a rollover of a previous debt facility primarily related to this equipment giving the company a total current debt burden of USD10 million dollars.

Dr. David Robson, Chairman and Chief Executive Officer of Tethys Petroleum, commented: "In 2011 we made significant progress on the key projects in Tethys. In Kazakhstan we drilled successful appraisal wells and made a new exploration discovery both significantly increasing our core reserves. The modeling work we have now completed based on these drilling results bodes well for the new appraisal/exploration wells we will drill in 2012 where success would see further reserves upgrades. The Aral Oil Terminal is now complete and will become operational imminently effectively doubling oil production. In Tajikistan we advanced the deep sub-salt exploration program with the completion of the graviometry survey, the results of which are very exciting and confirm our previous geological evaluation, indicating the possible presence of giant Jurassic reefs below the salt. Looking forward in 2012 the new final seismic survey will focus on the most prospective areas with the intention of firming up a location to spud a deep well."
