    Geochemical Evaluation confirms five hydrocarbon reservoirs, reconnaissance indicates at least two
                                 additional large hydrocarbon reservoirs.

The  Directors of U.S. Oil and Gas plc are pleased to announce results from the analysis of data  collected
at USOIL's exploration acreage in Hot Creek Valley, Nevada.  A final analysis of the results of geochemical
tests  from USOIL's Eblana Phase 1, Sections 1 (West), Section 2 (North) and Section 3 (South) survey areas
confirms five precisely defined hydrocarbon reservoirs.

Samples  were  analysed for hydrocarbon content using Magnetic Susceptibility (MS),  High  Resolution  Soil
Spectral  Analysis  (HRSSA), UV-Vis Spectroscopy, Iodine, and Soil Electrical Conductivity  (umhos).  These
analysis  methods are independent of one another and are used for the detection of hydrocarbon microseepage
phenomena related to potential oil and gas reservoirs at depth.

The five Reservoir areas, one straddling Section 1 (East) and Section 3 (South), three in Section 2 (North)
and  one  in Section 3 (South) yield a consistent halo anomaly.  Halos, circular or semi-circular features,
are  anomalous  hydrocarbon  seepage  phenomena detected at the surface,  representing  the  edges  of  the
hydrocarbon reservoir.

Reconnaissance  geochemical data indicates additional very large hydrocarbon anomalies in  the  area  lying
East of section 2 (North), West of Section 2 (North) and slightly smaller anomalies in the area to the East
and West of Section 3 (South).  Further work on these sections will form the basis for the Eblana Phase  II
work programme which is scheduled to start before the end of the fourth quarter of 2010.

Chief Executive Officer Brian McDonnell says, 'integrating this information into our existing datasets,  we
now  have  all  of  our Eblana Phase 1 prospect area targets identified. We intend to  put  an  operational
programme in place to bring these targets to the next stage of development.'

The Company will announce the spudding in date for its first well target in due course.

Notes to Editors

US  Oil  and  Gas plc is a PLUS (Ticker: USOP) listed oil and gas exploration company with  a  strategy  to
identify and acquire oil and gas assets in the early phase of the upstream life-cycle and mature them  into
marketable opportunities for the medium and large-sized oil companies. The Company's main asset is  in  Nye
County, Nevada where it holds the entire share capital of the US-based company Major Oil International LLC.
Major  Oil has acquired, and intends to acquire, rights to exploration and development acreage in two  high
potential resource areas in Hot Creek Valley, Nye County, adjacent to the oil and gas rich Railroad  Valley
area of Nevada, both of which are part of the Sevier Thrust of central Nevada and western Utah, USA.

The IPDS Passive Seismic Survey results reported on 26th February 2010 showed high DHI (Direct Hydrocarbons
Indicator)  readings for Section 2 (North), with DHI of 0.96.  This section was identified  as  the  likely
first well drilling target and which has now been staked and prepared for the first well drilling campaign.
DHI  readings  for  Section 3 (East) of up to 0.59 DHI, led USOIL to nominate this section  as  its  likely
second  well-drilling  target.   Geochemical results for Eblana Phase  I  indicates  five  clearly  defined
hydrocarbon reservoirs, with excellent correlation with IPDS and gravity/magnetic survey results.
