SAMSON OIL & GAS OPERATIONAL ADVISORY   Denver 1700 hours April 1st, Perth 0700 hours April 2nd, 2013

Samson Oil & Gas Limited ("Samson" or the "Company") (ASX: SSN; NYSE MKT: SSN) advises that the first four infill development wells on its North Stockyard field have commenced with the setting of a 16 inch conductor in each of the wells, establishment of the individual cellars and other preparatory work having been completed.

The wells that have been commenced are the following:

Duckstein 1-13-14H TF

Billabong 2-13-14H BK

Blackdog 3-13-14H TF

Sail and Anchor 4-13-14H BK

Wells with a “TF” designation will be completed in the first bench of the Three Forks Formation and those with a “BK” designation will be completed in the middle Bakken Formation. Each well will be “batch” drilled and the forward plan is to initially set the Frontier Rig 24 on the Duckstein location then drill and set surface casing at 2,300 feet. Following the Duckstein location, the rig will skid to the subsequent locations, setting surface casing in each of the four wells.

The Frontier Rig 24 has currently exited its manufacture point and is en-route to North Dakota. The first loads are expected on location later this week. Drilling operations are expected to commence with this rig in approximately 10 days.
