                 3D Passive Seismic Results Confirm Substantial Updip Reservoir on Lease Area

U.S.  Oil and Gas plc (PLUS: USOP), the oil and gas exploration company with its main asset in Nevada, USA,  is
pleased  to announce the results of its 3-D Infrasonic Passive Differential Spectroscopy (IPDS) survey recently
completed over the whole of its lease area.

A  report  prepared  by  Geodynamics Research confirms a large hydrocarbon anomaly consistent  with  previously
reported  geochemical  survey results and other data sets.  The anomaly covers more than  10  sq.km  and  shows
consistently  high  Reservoir Hydrocarbon Indicator (RHI) readings.   The hydrocarbon pool sits  updip  and  is
wholly contained within the lease area, while the source kitchen is underneath or just down-dip nearby.

US  Oil  has identified up to ten drilling targets over the whole lease area.  Of those ten, the most promising
three  are superior to the best target shown by the earlier 2-D IPDS survey using the RHI scale carried out  on
part of the lease area and reported in an earlier RNS dated 26 February 2010.

Work  continues to complete the process of estimating recoverable oil in place for the accumulation identified.
These  estimates  will  incorporate all data sets collected so far plus petrophysical  evaluation  of  recently
acquired  digitized  well log data from 11 wells in nearby Railroad Valley.  The final  analysis  is  currently
being  carried  out and will form the basis of a Prospective Resources report to be completed  in  due  course.
Meanwhile,  completion of administrative procedures and ground operational plans in relation to  the  Company's
three-well drilling programme are continuing as planned.

US Oil CEO Mr. Brian McDonnell said: "The 3-D IPDS survey results have exceeded our expectations.  The new data
has  identified drilling targets even more promising than before, and although this demanded considerable extra
time  in  data  analysis  and refining our model, we believe the result will be to minimize  uncertainties  and
further reduce the exploration risks associated with our forthcoming drilling campaign."
