Samson Oil & Gas Announces Updated Proved Reserves

Samson Oil & Gas Announces Updated Proved Reserves

DENVER & PERTH, Australia--(BUSINESS WIRE)-- Samson Oil & Gas Limited (ASX:SSN; NYSE MKT: SSN) today announced that, based on reports provided by Ryder Scott Company ("RSC"), an independent petroleum reserves engineering consulting firm, its Proved Reserves as of July 1, 2013, were estimated at 1.8 MMBOE with a Net Present Value at a 10% discount rate (NPV¹⁰) of $39.6 million using NYMEX pricing. Samson also announced its own internal estimate of Proved Reserves as of August 15, 2013, which adjusts for the impact of Samson's transactions since the end of fiscal 2013.

In particular, after considering the recent sale of part of its North Stockyard undeveloped acreage to Slawson Exploration Company, Inc., Samson estimates its Proved Reserves as of August 15^th at 1.55 MMBOE, with a value of $34.1 million using NYMEX pricing. It is noteworthy that, while Proved Reserves declined slightly as a result of the Slawson transaction, the August 15, 2013, figure still represents a substantial value increase from the most recent reserve report dated April 30, 2013, which estimated an NPV¹⁰ of $23.6 million.

Proved Reserve

As at June 30^th, 2013, RSC estimated Samson's reserves as follows:

The above estimate is based on SEC pricing which was $91.60 per bbl and $3.44 per MMBTU.

Utilizing NYMEX pricing at July 1, 2013, the RSC estimate is as follows:

The July 1 estimate is based on the following NYMEX pricing:

This compares to the April 30, 2013, estimate, which was based on SEC pricing:

Comparing the June 30^th to April 30^th, 2013:

Effect of Partial Sale of Undeveloped North Stockyard acreage

As previously advised, effective August 15th, Samson sold 50% of its undeveloped acres to Slawson for cash and other consideration. Because this transaction occurred after the end of Samson's fiscal year, its effect was not examined by RSC and is not reflected in their June 30, 2013 reserves report.

Samson believes it is important, however, to disclose its own internal calculations of the effect of the Slawson transaction on our Proved Reserves. Samson performed those internal calculations by subtracting 50% of the volumes and values from the RSC reserve estimates for the three Proved Undeveloped locations associated with North Stockyard that are included in the June 30, 2013, RSC report, which results in the following Samson estimate:

While Samson's August 15, 2013, internal estimate was derived from the RSC June 30, 2013, report and Samson therefore believes it to be a fair and reliable estimate as of that date, it does not reflect any other developments that may have occurred with respect to Samson's acreage between June 30 and August 15 other than the Slawson sale. Moreover, since RSC has not reviewed or approved Samson's August 15 internal estimate or updated the engineering data in its June 30 report to August 15, there is no assurance that RSC would consider Samson's estimate to be accurate.

Notes to Reserves Estimates

The reserves quoted in this release were estimated based on the definitions and disclosures guidelines contained in the Society of Petroleum Engineers, World Petroleum Council, American Association of Petroleum Geologists and Society of Petroleum Evaluation Engineers Petroleum Resources Management Systems.
