Reserves and oil production increases in Leavenworth County, Kansas

Sefton Resources, Inc. (AIM: SER), the independent oil and gas exploitation and production company with interests in California and Kansas announces the findings of an Independent Competent Persons Report produced by Dr Nafi Onat which assesses and estimates the future cash flow from the Company's oil and gas proved reserves and unproved resources in Leavenworth County, Kansas and reports on oil production in Kansas.

Highlights:

·; The report estimates the net present value (discounted at 10%) of cash flows from Sefton's oil and gas proved reserves and unproved resources in Leavenworth County, Kansas at this time at US$25.99 million (£17 million). This represents a ten-fold increase compared to the value of US$2.57 million which was reported as at the end of 2011.

·; The report demonstrates that Sefton has been successful in moving resources up into the proved reserves category, whilst dramatically expanding the resource capability in Leavenworth County, Kansas.

·; Oil production in Kansas in March 2013 increased to approximately 400 barrels a month, compared with the approximately 300 barrels of oil produced in February 2013.

·; Following the acceleration of the acreage leasing program in Leavenworth County, the Company now has assembled 14 separate project areas all with oil and gas potential.

Commenting today, Jim Ellerton, Chairman of the board said:

"Sefton is demonstrating the results of the time, effort and investment made in Kansas which has served to substantially increase the reserves and the net present value of its oil and gas assets in Leavenworth County. Monthly oil production continues from our ongoing workover and recompletion programme.

Currently our Kansas operations team is focusing attention on the Leavenworth County where oil and gas production is being developed initially as this location provided an opportunity to sell gas into an interstate pipeline and hence allow oil wells with associated gas to be brought on stream.

Later in the year, work will begin in Anderson County on the Waverly pipeline system to mirror the operation in that is being developed in Leavenworth County; at that stage a Competent Persons Report on Andersen County will be prepared."

Competent Persons Report on Kansas Oil & Gas Assets and Prospects

Dr Nafi Onat's report provides an independent geo-technical review and economic valuation of the properties for classifying the assets, and estimating the value of recoverable hydrocarbon reserves in the leases that are held by TEG-Midcontinent (Sefton 100%-owned subsidiary) in the Leavenworth County.

Oil price and operating costs were kept constant during the lives of the wells. Cash flow projections were generated assuming a 100% working interest and generally an 87.5% net revenue interest. A constant oil price of $90 a barrel was assumed. The gas price was assumed to be $3.50 per Mcf and escalated at 10% per year to a maximum of $6.00 per Mcf and then remaining constant during the lives of the wells.

This Competent Persons Report demonstrates that Sefton has been successful in moving resources up into the Proved Reserves category whilst at the same time dramatically expanding the resource capability.

Summary of Economic Analysis of TEG-Midcontinent

Leavenworth County 2012 Resources

For the purposes of its report, Sure Engineering used the Petroleum Resources Management System (PRMS) published by the Society of Petroleum Engineers / World Petroleum Council / American Association of Petroleum Geologists / Society of Petroleum Evaluation Engineers in March 2007 ("SPE PRMS"). Based on this system, hydrocarbon potential recoverable volumes are classified as reserves when economically recoverable volumes have been discovered, contingent resources when such discovered volumes are not currently considered economically recoverable and prospective resources when hydrocarbons are indicated but not actually discovered.

The report also estimates the PV10 value of future cash flows from Sefton's oil and gas proved reserves and unproved resources in Leavenworth County, Kansas at this time of US$25.99million (£17 million). This represents a substantial increase on the comparable value of US$2.57 million was reported as at the end of 2011; as is demonstrated in the table below.

Workover and recompletion programme

Oil production in Kansas in March 2013 increased to approximately 400 barrels, from the approximate 300 barrels of oil produced in February 2013. Additional production will come from ongoing workovers, improved infrastructure and Sefton's leasing programme together with the stimulation and recompletion of wells.

The acreage leasing program in Leavenworth County has been accelerated with Sefton acquiring target leases that had been highlighted by the ongoing engineering study and the Company's own internally developed geologic maps. Progress is such that the Company has now assembled a total 14 separate project areas all with oil and gas potential.

In accordance with the guidelines of the AIM Market of the London Stock Exchange, Jim Ellerton, Chairman of Sefton Resources, Inc. a qualified geologist with over thirty years oil & gas industry experience, is the qualified person as defined in the London Stock Exchange's Guidance Note for Mining and Oil and Gas companies, who has reviewed and approved the technical information contained in this announcement. Jim Ellerton has also relied on primary information supplied by staff and third party consultants in carrying out his review.

Third party gas supply agreements

The gas pipeline revenue is scheduled to begin once the Vanguard pipeline has been connected to the LAGGS-Southern Star interstate system. Discussions continue with third party gas suppliers that can provide the Company with sufficient gas to begin to flow gas economically into the Southern Star interstate system in addition to the Company's own gas. Ahead of moving to finalise these negotiations, the Company has now embarked on a programme of testing the gas of potential third party suppliers for BTU content and deliverability together with costing the hook-up to Sefton's pipeline system.

About Sefton

Sefton Resources is an oil and gas exploitation and production company with significant scope to grow its three projects in onshore United States that are 100%-owned and operated. The business strategy is to acquire long life, controlling interests, partially developed reserves and then to seek maximize shareholder value through asset development using the Company's own funds initially and then involve third party capital, farm-out or merger.

Currently Sefton has a market capitalisation of approximately £5 million and a dramatically higher unrisked PV(10) proved reserves and resources value. The key operational focus at this time is on developing three revenue sources from California and Kansas:

Enhanced Oil Recovery (EOR) projects in California

Sefton owns 100% of two oil fields In East Ventura County - Tapia (heavy gravity oil) and Eureka Canyon (medium gravity oil). Estimated 2011 year-end proved reserves stood at 3.8 million barrels. The current operational focus is to fully develop Tapia with an active well drilling and work-over programme in conjunction with the use of cyclic steam production enhancement. Sefton engaged Petrel to construct a geologic model to be utilised by Dr Farouq Ali, a recognised expert, in a thermal stimulation study to optimise production and reserve development for Tapia. Of all Sefton's operations, Tapia generates the majority of the revenues, at this time.

Exploration and Production in Kansas

In East Kansas, Sefton has a significant and growing acreage position (Leavenworth and Anderson Counties) in the Forest City Basin, where conventional oil and gas deposits as well as coal bed methane (CBM) prospects have been identified. The current operational focus is in Leavenworth County where a workover, recompletion and leasing programme is under way that will see oil, gas and CBM wells brought back into production with first revenues from oil whilst additional gas assets are being assembled for the future development as all the pipelines become operational.

Natural Gas Transmission in Kansas

Three gas pipelines have been acquired by Sefton. The LAGGS pipeline in Leavenworth County has been fully refurbished and is now connected to the Southern Star Interstate Pipeline system which allows sales outside the local Kansas market. Plans are to join the Vanguard pipeline to the LAGGS system in Leavenworth County which will increase the scale of this gathering system. This means Sefton will be able to transport its own gas as well as third party gas to market and generate additional revenues.

A third pipeline in Anderson County is planned to be connected to an interstate pipeline system in the future to provide additional opportunities for redevelopment of oil, equity and third party gas.
