Tethys Petroleum today announced its third quarter 2012 financial results. The results are highlighted by a 46% increase in production revenues over the third quarter of last year.

RECENT FINANCIAL HIGHLIGHTS

Q3 2012 vs Q3 2011


--  Total Oil and Gas Revenue up 46% at USD10.0 million 
--  Average oil production from the Doris field, Kazakhstan up 74% at 2,732
    bopd 
--  Administrative costs down 8% at USD4.5 million 
--  Total Assets USD252.1 million 

9 months 2012 vs 9 months 2011


--  Total Oil and Gas Revenue up 72% at USD26.7 million 
--  Average oil production from the Doris field, Kazakhstan up 145% at 2,234
    bopd 
--  Administrative costs down 2% at USD15.5 million 

The 9 months period in 2012 has seen a substantial increase in oil production and revenue from the Doris oil field in Kazakhstan with a small drop in corporate administrative costs over the same period. It is forecast that both these trends will continue into 4Q 2012. On the revenue side both October's and November's average oil production figures have so far contributed toward the best quarter of oil production in Kazakhstan to date. October oil production averaged approximately 3,700 bopd and it is forecast that Novembers' production figures will exceed this number. These figures demonstrate the optimisation of the trucking operation in Kazakhstan is coming to fruition which has been the main restriction on maximum production to date, not the production capability of the wells.

On the costs side in Q3 the Company has initiated a review of all costs with a particular focus on administrative expenses. The objective of this exercise is first and foremost to review all areas with a view to reducing costs but particularly administrative costs, and secondly to review the categorization of costs to ensure that the Company is reporting consistently with other similar oil and gas companies, which will facilitate appropriate comparison within its peer group.

Some of these measures can be seen in a 22% reduction in the Q3 2012 costs over the Q2 2012 costs and in the 8% reduction against Q3 2011, but it is expected most of the effect will be realised in the quarters to come as this assessment and resulting action takes some time to implement. This cost reduction exercise does not in anyway reflect the growth prospects of the Company which, as can be seen from the higher production and revenue growth in Kazakhstan and the recent signing of the MOU for a Tajikistan farm-in partner, are very good.

The Company reports financial results in accordance with International Financial Reporting Standards ("IFRS").

The following disclosure is provided to comply with regulatory requirements:

During the fourth quarter of 2011 and the first quarter of 2012, the Company borrowed from various lenders an aggregate principal amount of USD10 million for the purpose of re-financing the purchase price of drilling rigs. The loans are evidenced by loan notes having a maturity of one year or two years. The lenders also received warrants to purchase ordinary shares of the Company having a term of one year or two years, corresponding to the term of the loan notes. In October 2012, the Company received approval from a number of lenders to a one-year extension of the maturity date of loans notes in the principal amount of USD2,165,240 maturing in December 2012. In connection with the approval of the extension of the maturity date, the Company agreed, subject to definitive lender approval, to extend by six months the expiry date of 1,575,000 warrants issued in December 2011 (having an exercise price of CAD0.58 to CAD0.65) and 3,017,380 warrants issued in February, March and April 2012 (having an exercise price of CAD0.84 to CAD1.18), excluding warrants issued to insiders of the Company. The number of ordinary shares into which these warrants may be exercised represents, in aggregate, 1.6% of the number of ordinary shares outstanding on the date hereof. The exercise prices of these warrants represent a premium of 14% to 27% in the case of the warrants issued in December 2011 and 64% to 131% in the case of the warrants issued in February, March and April 2012 of the volume weighted average trading price of the ordinary shares of the Company on the TSX for the five days to October 19, 2012, being the date of the agreement with the lenders. The change to the expiry dates of these warrants will be effective on November 29, 2012. The Company will also issue, subject to definitive lender approval, 1,082,620 warrants having an exercise price of $0.64 to lenders who agreed to extend the maturity date of their one year loan notes by 12 months. These warrants will expire on certain dates in December 2013 or, in the case of 307,620 warrants issued to two officers of the Company, June 2014. The number of ordinary shares into which these new warrants may be exercised represents, in aggregate, 0.4% of the number of ordinary shares outstanding on the date hereof (0.1% in respect of the warrants to be issued to the two officers of the Company). The exercise price of the new warrants represents a premium of 25% of the volume weighted average trading price of the ordinary shares of the Company for the five days to October 19, 2012.

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.
