SAMSON OIL & GAS LIMITED JOINT VENTURES WITH DEVON IN THE ▇▇▇▇▇▇ SHALE

Denver 1700 hours April 29, Perth 0700 hours April 30, 2008

Samson Oil & Gas Limited (“Samson”) has executed an Exploration Agreement with Devon Energy Production Company (“Devon”). The agreement covers ▇▇▇▇▇▇’▇ 6,400 acre holding in the western flank of the ▇▇▇▇▇▇▇▇▇▇ Basin in Sweetwater County, Wyoming. This area contains a 3,500 foot section of ▇▇▇▇▇▇ Shale which was drilled in the 1970’s and recovered a significant flow of gas from an unstimulated ▇▇▇▇▇▇ Shale. Since that time there has been significant development of the ▇▇▇▇▇▇ Shale in the ▇▇▇▇▇▇▇▇▇▇ region 40 miles east of Samson’s acreage, where our competitors have expended significant funds that have resulted in flows of up to 9 mmcfpd from the ▇▇▇▇▇▇ Shale.

The Exploration Agreement envisages that a 3D seismic grid will be acquired in an effort to define an exploratory program. Devon will operate the seismic acquisition and any subsequent exploratory program. ▇▇▇▇▇▇ anticipates that the seismic acquisition will be undertaken in the summer of 2008. ▇▇▇▇▇▇ will hold a 50% interest in the leasehold block unless ▇▇▇▇▇▇ permits a third party to complete the second farm-in well in the Greens Canyon area and earn an 18% equity stake in Samson’s leases. In that circumstance, ▇▇▇▇▇▇ would retain a 32% equity interest in these leases.

The acquisition of 3D seismic is a necessary first step in the evaluation process such that naturally occurring fractures systems can be identified and evaluation drilling. This appears to be one of several technical keys to the successful flow rates seen to date in the ▇▇▇▇▇▇▇▇▇▇ region.

▇▇▇▇▇▇’▇ agreement with Devon Energy would appear to complement their existing lease holding which is shown on the attached map. This map shows both ▇▇▇▇▇▇’▇ acreage (in yellow) and Devon’s (in green).

▇▇▇▇▇▇’▇ Ordinary Shares are traded on the Australian Securities Exchange under the symbol "SSN". ▇▇▇▇▇▇'▇ American Depositary Receipts (ADRs) are traded on the American Stock Exchange under the symbol "SSN", and, each ADR represents 20 fully paid Ordinary Shares of Samson.
