Samson Oil & Gas Limited (ASX: SSN; NYSE MKT: SSN):

June 30th Reserves

Netherland Sewell, & Associates Inc. has completed Samson’s June 30th reserves estimate and it is as follows:

                  OIL MBBL   GAS MCF   NPV10 MM PDP   4,173   3,608   $62.570 PDNP   1,230   2,252   $16.196 PUD   5,400   3,780   $47.283 TOTAL PROVED   10,803   9,640   $126.049      

This compares with an internal estimate generated as at February 1st, 2016:

                  OIL MBBL   GAS MCF   NPV10 MM PDP   3,179   2,493   $36.045 PDNP   1,189   2,241   $11.284 PUD   3,344   2,341   $17.609 TOTAL PROVED   7,712   7,074   $64.939      

These estimates have been made using the NYMEX strip at the applicable date, adjusted for delivery and quality differentials.

The estimate uses variables that are particular to each well, based on historical data, but generally the variables for the Foreman Butte project, which constitutes the bulk of the reserves, have the following parameters:

a) A PUD well cost at $2.8 million.b) The PUD wells use a type curve that generates a EUR of 380,000 bbls.c) A realized oil price differential of $6 to WTI.d) A fixed operating cost of $3,400 per month per well.e) A salt water disposal cost of $1.50 per barrelf) Negligible value is attributable to gas sales.

The substantial increase from February 1 to June 30 can be attributed to three factors.

Oil Price

First, the oil price strip as at June 30th has increased, compared to that used in the February 1st estimate.

          Period Ending  

February 1st Oil Price($/Barrel)

 

June 30th Oil Price($/Barrel)

February 2016   39.63     December 2016   36.95   49.42 December 2017   42.36   52.17 December 2018   44.93   53.69 December 2019   46.74   54.60 Thereafter   48.07   55.43    

PDNP Conversion

Second, following its assumption of Operatorship in the Foreman Butte Project in early June, Samson engaged five work over rigs to restore an additional 32 wells to PDP status. This activity, which cost around $800,000, resulted in a $12 million NPV10 addition to the reserve estimate as at June 30th.

Infill Development Planning

Third, during the intervening period, Samson developed a definitive infill development plan for the Foreman Butte Field and the first three drill spacing units have been submitted to the regulatory authorities for approval. This plan, when fully implemented, will see 17 PUD locations drilled in Foreman Butte along with an additional well in the R Field, which is the high value well in the portfolio. This planned infill development fits inside the defined limits of each field that were established through previous drilling activity. As a result, the value of the PUD category has increased substantially.

We are continuing to develop the reserve base in terms of behind pipe reserves and additional drilling opportunities. We expect further additions to emerge once that technical analysis is complete.

Cost reduction

Since acquiring the Foreman Butte project, Samson has reduced the operating cost within the project from $22 to $12 per barrel. The lower lifting cost is common to both the February and June reserve estimates. It is important, however, that Samson’s cost experience after becoming operator has confirmed the assumptions made in the February estimate.

Samson remains focused on reducing costs further, and have identified several areas where we believe further cost reductions are achievable.

Foreman Butte Project Reserves

The acquisition of the Foreman Butte Project was financed on a February 1st reserves report, which was as follows:

                  OIL MBBL   GAS MCF   NPV10 MM PDP   2,148   1,049   $22.755 PDNP   1,189   2,241   $11.284 PUD   3,344   2,341   $17.609 TOTAL PROVED   6,680   5,631   $51.648      

This compares to the June 30 estimate for Foreman Butte project:

                  OIL MBBL   GAS MCF   NPV10 MM PDP   3,243   1,973   $45.818 PDNP   1,230   2,252   $16.196 PUD   5,400   3,780   $47.283 TOTAL PROVED   9,873   8,005   $109.297      

This comparison demonstrates that the Foreman Butte project’s PDP reserve has increased by more than 100%, which more than replaces the reserves to be sold in the North Stockyard field.

North Stockyard Sale

As previously announced, Samson has executed a purchase and sale agreement with respect to its interest in the North Stockyard field and accepted a $1 million nonrefundable deposit as part of the $15 million consideration. We are expecting the buyer of this asset to close the transaction mid to late September. As a result, after the closing Samson’s pro forma June 30th reserves will be reduced as follows:

                  OIL MBBL   GAS MCF   NPV10 MM PDP   3,342   2,286   $47.242 PDNP   1,230   2,252   $16.196 PUD   5,400   3,780   $47.283 TOTAL PROVED   9,971   8,318   $110.720      

Samson’s proved reserves will have nevertheless almost doubled compared to its February 1st estimate.

Debt Facility

As previously announced, the proceeds of the North Stockyard sale will be used to reduce our debt to $19 million, and to fund the immediate working capital requirements of the company.

After the North Stockyard sale Samson will have a theoretical borrowing base well in excess of its current draw. While there is no assurance of the availability of additional capital, Samson is optimistic that its improved reserves will provide it with the capital opportunities for further expanding the Foreman Butte asset base through production enhancements and infill development drilling.

Samson’s Ordinary Shares are traded on the Australian Securities Exchange under the symbol "SSN". Samson's American Depository Shares (ADSs) are traded on the New York Stock Exchange MKT under the symbol "SSN". Each ADS represents 200 fully paid Ordinary Shares of Samson. Samson has a total of 3,215 million ordinary shares issued and outstanding (including 230 million options exercisable at AUD 3.8 cents), which would be the equivalent of 16.08 million ADSs. Accordingly, based on the NYSE MKT closing price of US$0.765 per ADS on September 9th, 2016, the Company has a current market capitalization of approximately US$12.3 million (the options have been valued at an exchange rate of 0.7652). Correspondingly, based on the ASX closing price of A$0.005 for ordinary shares and a closing price of A$0.001 for the 2017 options, on September 9th, 2016, the Company has a current market capitalization of approximately A$16.1 million.
