SAMSON OIL & GAS ANNOUNCES CURRENCY EXCHANGE RATE FOR AMERICAN DEPOSITARY SHARES IN RIGHTS OFFER

Denver 0600 hours, Perth 2000 hours June 11th, 2013

The Directors of Samson Oil & Gas Limited (NYSE MKT: SSN; ASX: SSN ) advise that the final purchase price, in US dollars, for holders of American Depositary Shares participating in Samson’s non-renounceable rights issue was $0.4752 per ADS plus a depositary fee of $0.005, for a total purchase price of US $0.4802. As previously announced, the US dollar price was based on the latest currency exchange rate reported by the Reserve Bank of Australia on June 10^th of US $0.9504 to AUS $1.00. Because the final US dollar purchase price is $0.0898 lower than the $0.57 deposit paid in by ADS holders who elected to participate in the rights offer, those participants will receive a refund of that amount from the depositary for each right exercised.

For each ADS right, participants are receiving one (1) ADS and eight (8) four year options to purchase Samson’s ordinary shares at an exercise price of AUS $0.038 per ordinary share, which are equivalent to four tenths (0.4) of a warrant to purchase one (1) ADS. At the June 10^th exchange rate, a full warrant consisting of twenty (20) options to purchase ordinary shares, or one (1) ADS, would have an exercise price of $0.722304 per ADS, plus a depositary issuance fee.

Samson previously announced that it raised gross proceeds of AUS $2.86 million from ordinary shareholders and ADS holders. Based on the latest currency exchange rate, the total gross proceeds of the rights offer from ordinary shareholders and ADS holders was US$2,716,401.

The aggregate cash proceeds of the rights offer attributable to rights exercised by holders of ADSs, which were payable to Samson in US dollars as determined by the June 10^th exchange rate, net of the issuance fee to the depositary, were US $1,875,546.
