Geochemical Results Eblana Sect 1 and 3 - Structures Identified Similar to Producing Wells in Region
Further analysis of the results of geochemical tests from USOIL's Eblana Phase 1, Sections 1 (West) and 3
(East) survey areas confirms the presence of oil and indicates structures that are analogous to the nearby
oilfields in Trap Springs, Railroad Valley, 20 miles to the east. This result confirms the Company's choice of
Section 3 (East) as its second well-drilling target. Detailed analysis of data from Section 1 (West) shows
that a massive fault (SW/NE) lies through Section 1 (West) and Section 3 (East).
Samples have now been analysed for Magnetic Susceptibility (MS), High Resolution Soil Spectral Analysis
(HRSSA), and hydrocarbon content. by UV-Vis Spectroscopy, Iodine, and Soil Electrical Conductivity (umhos).
These analysis methods are independent of one another.
Section 3 (East) yields a consistent halo anomaly towards the southeast of the survey area. Halos, circular or
semi-circular features, are anomalous hydrocarbon seepage phenomena detected at the surface, representing the
edges of the hydrocarbon reservoir at depth. Such features help pinpoint the optimal position for drilling.
Compositional information for Section 1 (West) was extracted from the hydrocarbon data using ratios of the
spectral wavelengths (240nm / 340nm) over the entire absorption range. This analysis compares low molecular
weight straight chain alkanes to high molecular weight aromatic rings. Results show a build up of gas along
the area previously discussed as being a diagonal linear anomaly. Section 1 (West) exhibits a diagonal linear
anomaly that is indicative of a massive fault, a geological barrier, or a geochemical barrier.
Surface structure interpretation shows that the lease area appears to be part of a major fault, with the
orientation of en echelon faults west of Hot Creek striking approximately East - West or Northeast - Southwest.
Faults east of Hot Creek strike approximately North - South.
The major finds in Railroad Valley are associated with similarly oriented faults, and when these locations are
analysed by age they exhibit a strong relationship to USOIL's Section 3 (East). The location of the halo and
associated anomaly coincides closely with the older faults in the survey area.
Chief Executive Officer Brian McDonnell says, 'Our analysis shows Section 3 (East) exhibits an anomalous halo
coincident with existing faults and fractures similar to those associated with prolific production in Railroad
Valley, an extremely encouraging result. We will now look closely at what is happening in Section 1 (West) and
the tremendous fault running diagonally across the survey area.'
The geochemical results for Section 3 (East) will now be integrated with the geophysical, geochemical and
passive seismic information already collected, to complete the stratigraphic picture for the second of USOIL's

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. 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. Positive geochemical results for Section 2 (North) have already
been reported. Seepage of hydrocarbons from the subsurface at Section 3 (East) is now also confirmed,
correlating highly with IPDS and gravity/magnetic survey results.
