SSN Samson Oil and Gas Limited

Samson Oil and Gas USA, Inc, a wholly-owned subsidiary of Samson Oil and Gas Limited (ASX:SSN and OTCQB:SSNYY), has entered into a Purchase and Sale Agreement (PSA) with Eagle Energy Partners I, LLC (Eagle) for the sale of Samson’s Foreman Butte Project located in the Williston Basin in North Dakota and Montana, effective January 1, 2018, for cash consideration of US$40 million (subject to customary adjustments).

The PSA provides for a US$1 million deposit that is fully refundable if Samson shareholders do not approve the transaction or Eagle finds title or environmental defects above a prescribed threshold, and is partially refundable if Eagle has not secured sufficient debt financing to complete the transaction.

Samson will also retain a non-operated 15% working interest in the Home Run Field, which is believed to contain the bulk of the identified upside of the project.

A shareholder meeting to seek approval for the transaction is currently planned for August 6th.

The transaction will allow Samson to retire all of its debt, meet all of its other liabilities and retain a cash balance of approximately US$6.7 million. The retention of a 15% working interest in the Home Run Field will allow Samson to participate in development of the Proved Undeveloped Reserves within the Ratcliffe Formation associated with the Home Run Field along with the Probable Reserves within the Nesson Formation in the same field. Samson has previously identified 26 well locations with the Ratcliffe Formation that could be drilled out of the existing well bores. The Nesson Formation opportunity includes 10 vertical wells in a well-defined structure which was proven to be productive from the Nesson Formation when penetrated in the Banks well, but for mechanical reasons has remained undrained.

Eagle has advised Samson that it intends to develop these opportunities, including 9 wells in the balance of 2018 and another 9 wells in 2019. Samson expects to have sufficient funding to participate in this drilling program. Samson will also be able, if it so determines, to propose and drill some of these wells for its own account pursuant to the Joint Operating Agreement to be entered into with Eagle at closing.

Commodity prices used in this estimate are as at May 31st and have been adjusted for transport and quality differentials to therefore represent a realized well head price. The commodity prices before applying this differential are as follows:

                  Oil                 Gas 2018                 $67.15                 $2.965 2019                 $63.156                 $2.796 2020                 $59.343                 $2.698 2021                 $56.662                 $2.666 2022                 $54.834                 $2.685 2023                 $53.543                 $2.738                                

The PDP and PDNP reserve estimates and forecasts of future production rates are based on historical performance and analogy data. If no production decline trend has been established, future production rates and decline curves are based on analogous wells. If a decline curve is established, this trend is used as the basis for estimating future production rates.

The reserve estimates utilize historical operating costs of the wells and leases, subject to the report, and are held constant for the life of a well. Development costs are based on authorizations for expenditure for the proposed work or actual costs for similar projects. Abandonment costs are assumed to be offset by the salvage value as all of these projects are located onshore.

The reference point used in the reserve estimates is the sales point, and the reserves and their value are wholly attributable to the Consolidated Entity’s economic interest, net of royalties, operating and development costs, and production and ad valorem taxes.

PUD estimates are based on a drill and complete estimated expenditure of US$375,000 per well. As these wells are infill drilling, all offtake and production infrastructure is readily available. Four drilling permits have been received by the Company, these will be transferred to Eagle following the completion of the sale, allowing drilling to commence as soon as practicable.
