                                         ("U.S. Oil" or the "Company")

Operations Update: Eblana #1

U.S.  Oil & Gas plc (GXG: USOP), an oil and gas exploration company focused on Nevada, USA, announces that  the
Eblana  #1  exploration  well,  being  drilled by its wholly owned subsidiary  Major  Oil   International  LLC,
encountered  nine  large  potential porous oil reservoir intervals (approx. 1,100  feet)  and  associated  high
fracture  zones before reaching its target depth of 8,550 feet on 26th May 2012. The initial interpretation  of
well logs confirms all of the hydrocarbon shows and reservoir intervals previously recorded while drilling.

Because  of  the large total size of the reservoir zones and the complex lithological  heterogeneities  in  Hot
Creek  Valley,  further  advanced  well log processing and interpretation is  currently  being  undertaken  for
reservoir characterization studies in order to select the optimal production zones for perforation and testing.
No flow testing has taken place.

The  production wellhead has been installed. A specialist work-over drilling contractor required to perform the
production tests will move on to site once the downhole multiple reservoir analysis is complete.

CEO  Brian  McDonnell  said, 'The number and size of the reservoir zones we encountered  was  well  beyond  our
expectations.   Baker  Hughes, who conducted all of the testing, are carefully analysing and  interpreting  the
data and when complete flow testing will commence.'
