SAMSON OIL & GAS ADVISES ON
NORTH STOCKYARD FIELD AND
RODNEY #1-14H WELL
Denver 1700 hours March 14th, Perth 0700 hours March 15th 2011.
Samson Oil & Gas Limited (ASX: SSN, NYSE AMEX: SSN) advises that the fracture stimulation
equipment is on location and rigged up on the Rodney #1-14 well. The stimulation job is expected
to take approximately 4 days, during which the 16 stages will see a planned 2 million pounds of
proppant placed.
The Rodney #1-14 well was drilled to a total measured depth of 17,222 feet and is Samson?s fourth
production well in the field.
Samson?s fifth well, the Earl #1-13, is expected to be stimulated on March 28th, however this date
might be displaced because of a competing well which is ahead in the frac schedule is likely to be
delayed such that March 28th date is maintained.
The sixth well, the Everett #2-15 (previously referred so as the Harstad #2-15), which will be the
final well to develop the Bakken Formation on a 640 acre spacing, has an expected spud date of
May 1st.
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 AMEX under the symbol "SSN". Each ADS represents 20 fully paid Ordinary Shares of
Samson. Samson has a total of 1,996 million ordinary shares issued and outstanding (including

ADSs. Accordingly, based on the NYSE AMEX closing price of US$3.15 per ADS on March 14th,
2011 the company has a current market capitalization of approximately US$315.31 million.
Correspondingly, based on the ASX closing price of A$0.17 on March 14th, 2011, the company has
a current market capitalization of A$336.18 million. The options have been valued at their closing
price of A$0.16 on March 144th, 2011 and translated to US$ at the current exchange of 1.0076 for
the purposes of inclusion in the US$ market capitalization calculation.
