Corporate Highlights

— Drilling of a further 3 successful shallow gas exploration wells: AKK17,

AKK18 and AKK19. These wells have a predicted test capacity of over 20

million cubic feet (570,000 cubic metres) of gas per day based on nearby

similar well results. Further shallow well drilling is planned as well

as tie in of these and other wells to increase production of natural gas

— Independent report commissioned on the “Klymene” prospect in Kazakhstan

estimated Unrisked Mean Recoverable Oil Resources at over 400 million

barrels. The Klymene exploration well is planned for later this year

following successful completion of the recently announced SinoHan

acquistion

— Completion of the acquisition of a 56% interest in Blocks XIA, XIM and

XIN, in eastern Georgia; areas which the Company believes have good

potential for both unconventional and conventional oil, with independent

estimates giving some 1.8 billion barrels oil equivalent of Unrisked

Mean Recoverable Resources to Tethys’ interest

— Selection of seismic contractor for the next phase of the geophysical

acquisition on the Bokhtar PSC in Tajikistan by the joint

Tethys/TOTAL/CNPC joint operating company BOC

operations (Q1 2013: USD0.02 cents)

— Oil and gas revenue from continuing operations of USD6.8 million – a
