SANTA ROSA, ARGENTINA UPDATE
Oromin Explorations Ltd.

("Oromin") through the Argentina subsidiary, Exploraciones Oromin S.A.
("Oromin") reports that on July 26, 2009, exploration well OLE.MD.SRE X-2001 reached a total depth
of 1,270 metres in basement.
Initial electric logging and subsequent MRIL (magnetic resonance imaging) evaluation completed late
July 27, 2009 confirms that the well has not encountered hydrocarbons.

The results suggest that the
target reservoir zones are not present at this crestal well location.
The interest holders of the Santa Rosa license (indirectly Oromin as to 67.52% and Australian Otto
Energy Limited as to 32.48%) will now study the well data and incorporate this in a regional data base to
determine whether potential stratigraphic traps on the western flank of the Santa Rosa dome warrant
further investigation.
The well will be plugged and abandoned as a dry hole.
A National Instrument 51-101 compliant technical report on this prospect was filed on SEDAR on July
9, 2008 and is available at www.sedar.com
Norman Haimila, Ph.D., petroleum consultant and Oromin"s Country Manager, is the Company"s
"qualified evaluator" for the purposes of National Instrument 51-101 and has verified the data disclosed
in this news release.

Dr.

Haimila is a member of the American Institute of Petroleum Geology and the
American Association of Petroleum Geologists.
