May 29, 2012

ALMATY, KAZAKHSTAN, Jun 29, 2012 (MARKETWIRE via COMTEX) –Tethys Petroleum Limited (TSX: TPL)(LSE: TPL) today announced that its Kazakh subsidiary had reached agreement on a USD 16.5 million loan facility.

This facility is provided by a Kazakh bank to Tethys Aral Gas, a wholly owned Kazakh subsidiary of Tethys, and is available to fund capital expenditures in Kazakhstan. It can be drawn down at any time but the company is under no obligation to do so.

This facility has a term of up to four years depending on the company’s requirements and bears an interest rate of 14% per annum on sums drawn down. It is to be secured against field facilities in Kazakhstan. An initial USD 3.5 million of this facility has been drawn down.

Bernard Murphy, Chief Financial Officer, stated “This facility provides flexibility to meet the company’s possible funding requirements should the company wish to make use of it and I believe it is prudent financial management at this time.”

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.
