Operations Update: Eblana #1

U.S.  Oil  &  Gas  plc  (GXG: USOP) an oil and gas exploration company focused on Nevada, USA,  is  pleased  to
announce  that the Eblana #1 exploration well currently being drilled by its wholly owned subsidiary Major  Oil
International LLC reached a depth of 7,474 feet on 23rd May 2012 at 22.00 hours PST.

Oil shows observed and samples collected while drilling indicate multiple potential hydrocarbon pay zones.   An
estimated  gross section of up to one thousand feet of hydrocarbon shows (with possible gas/oil net  pay  zones
ranging  from  100 to 300 ft) has been encountered within volcanic ash conglomerates integrated with  sandstone
interbed zones, whilst further oil shows have been encountered in the deeper reservoir horizons currently being
drilled.

Good hydrocarbon background gas with several high gas peaks (C1, C2 and C3) associated with bright yellow color
florescence  and  streaming cuts have been recorded. At several depth intervals, laboratory retort  hydrocarbon
analysis  of  bottom-up mud circulation tests of recovered fluid samples indicated light oil, with evidence  of
sweet gas at the shaker.

The bottom up test completed on the open hole at 00.30 on 24th May PST saw good light gravity oil recovered  at
the  surface.  Subsequent  laboratory  analysis confirmed a bright yellow  white  fluorescence  indicating  the
presence of live light oil.


A  logging and production testing program, including the zones discovered to date and any deeper potential  pay
zones encountered, will be carried out when target depth is reached.

US  Oil & Gas CEO Brian McDonnell said, 'We are highly encouraged by the results of our drill thus far and look
forward keenly to the next stages in our exploration process.'
