SEFTON RESOURCES SIGNS LETTER OF INTENT TO PURCHASE ADDITIONAL ASSETS IN KANSAS AND ANNOUNCES YEAR-END 2010 PROVED RESERVES

10 February 2011

Sefton Resources, Inc. (AIM:SER), an independent exploitation and production company with assets in the East Ventura Basin of California and the Forest City Basin of Eastern Kansas, today announces its intention to purchase additional assets in Eastern Kansas and year-end 2010 reserves.

Additional Kansas Assets:

On 3 February 2011 the company signed a Letter of Intent ("LOI") that gives it exclusive rights to execute and close a Purchase and Sale Agreement with Cholla Production LLC ("Cholla") by the end of March 2011. Sefton acquired a pipeline from Cholla in 2010 (please refer to announcements made 3 March 2010 and 11 January 2011). The additional assets acquired from Cholla consist of approximately 1,200 net leasehold acres, 18 wellbores which are capable of recompletion and associated technical data. The purchase price agreed in the LOI is US$200,000. Final closing of this transaction is subject to the successful execution of a Purchase and Sale Agreement.

Year-End 2010 Proved Reserves:

Sefton's proved reserves totalled 3.8 million barrels at year-end 2010. The Company grew proven 2010 reserves by 7.45% compared with 2009 and replaced 512% of its estimated 2010 net production volumes. The changes from 2009 year-end estimated proved reserves to 2010 year-end estimated proved reserves included production of approximately 51,225 barrels of oil and upward revisions of 262,290 barrels of oil. Additions, including revisions, were primarily attributed to the Company's successful cyclic steam pilot program in Tapia Field, which was initiated in 2009.

The present value of the estimated future net cash flows from estimated proved reserves before income taxes using a 10% discount rate (PV10) was approximately US$80.6 million using a 12 month average blended price per barrel of US$71.38 for Tapia and Eureka Canyon Fields. Using strip prices as of 31 December 2010, the pre-tax PV10 value of Sefton's proved reserves would have been US$109.9 million. The estimated year-end proved reserves of 3.8 million barrels includes proved developed ("PD") reserves of 1.6 million barrels and proved undeveloped ("PUD") reserves of 2.2 million barrels. In addition, there are 2.3 BCF of estimated possible gas reserves at year-end 2010 associated with the Company's Eastern Kansas assets.

All of Sefton's 2010 year-end estimated proved and possible reserves were independently estimated by Reed W. Ferrill & Associates Inc.
