                                Operations Update


- Consistent flows established
- Two producer zones confirmed 
- Two grades of oil so far identified, including condensate
- Testing indicates sweet crude oil of API 28.5 and API 33
- Testing to be paused for data analysis and resumed on completion of analysis
- ADR preliminaries completed

U.S. Oil & Gas Plc (GXG:USOP), the oil and gas exploration company with exploration assets
in Nevada, is delighted to announce that it is achieving consistent flow from its Eblana 1
well in Hot Creek Valley.  Although current indications are that the well may prove to be 
commercial, the Company wishes to emphasise that testing is still at an early stage and no 
headline flow rates are available at this point.  

The Company intends pausing testing in early March in order to complete further data analysis.  
It expects to resume testing within eight weeks.  

Preliminary results:

In a 48-hour pump-assisted hydraulic swabbing and downhole pump test, one of the zones, found
between 7,000 and 7200ft, produced a continuous flow of crude oil and water.  Laboratory 
results have confirmed the crude oil from this zone is 28.5 API with a trace of contaminants 
and no hydrogen sulfide.   A second interval has produced light crude oil and water with an 
API of 33.  The zone of origin is currently being identified.
During circulation bottom up, there was a clear indication of condensate from one zone, the 
source of which will be determined following analysis and further testing.

In addition to the proven discovery area, the current testing programme has also confirmed an 
additional 8-10 potential drilling locations for several prospective pools to the south and 
south west of Eblana 1 and within the US Oil lease area in Hot Creek Valley. 

Further testing

The next stage will involve further data analysis and planning to guide future perforation 
within the flowing zones in order to confirm stabilized production rates and maximize production.  

The Company wishes to emphasise the critical importance of taking the necessary time for this 
preparation before commencing further testing.  The geology encountered has proved extremely 
complex, as expected in Nevada, and a careful and systematic approach has been taken.  The Company 
is pleased to report that its operations have been highly efficient, and it is confident that it 
is gaining a thorough understanding of the productive reservoir zones.  

American Depositary Receipts (ADRs)

U.S. Oil and Gas plc has appointed Deutsche Bank Trust Company Americas as depositary bank 
for its proposed American Depositary Receipt (ADR) programme, and that it has reached an agreement 
in principle with Deutsche Bank regarding the terms of the ADR programme. Further details will be 
Commenting on developments, CEO Brian McDonnell said, "Although the testing of Eblana 1 is ongoing, 
we are enormously encouraged by the results so far.  We have a producing well which, subject to 
further testing, we believe may prove commercial.  For a first exploration well in an unproven 
location this is a remarkable result, and we are delighted by the achievement.  The issuing of 
ADRs will also be a significant step forward for the Company." 

The Company confirms that it is in compliance with all Nevada Division of Minerals and Bureau of Land 
Management regulatory requirements.

U.S. Oil and Gas plc for the purchase or sale of any securities nor does it constitute a solicitation
