31st January 2011 GOLD OIL PLC ("Gold Oil" "Gold" or the "Company") Colombia Operations update -Rosablanca -2 plugged and abandoned Gold Oil, the AIM-listed oil and gas exploration and production company, primarily focused on opportunities in Latin America, makes the following update on its operations in Colombia. Rosablanca-2: Gold Oil announces that the Rosablanca-2 well reached a total depth of 2,883 feet and has now been plugged and abandoned following unsuccessful testing. Since entering the Tablazo and Rosablanca formations last week, drilling had encountered numerous oil and gas shows. Identification of liquid hydrocarbons on electric logs led to a decision to undertake two drill stem tests (DST) in both the Rosablanca and Tablazo formations. A DST in the Rosablanca Formation failed to flow indicating that reservoir to be tight and non-commercial. A second DST in the Tablazo Formation flowed formation water only. Gold  signed an  agreement with  the Colombian company Montecz SA, whereby Montecz  pays  100% of  the  costs  (up  to  US$2million)  of  the Rosablanca-2 well  in the Rosablanca Block of the Middle Magdalena Basin onshore Colombia. The well is expected to come in under budget. Gold Oil was effectively free carried on the exploration well. The joint venture will evaluate the results of this well over the coming months to determine the remaining prospectivity of the Rosablanca block and determine what future exploration activities, if any, are warranted there. Gold Oil retains a 25% interest in the permit.  For further information on the Company, visit www.goldoilplc.com or contact: Gold Oil Plc John Bell - Chairman                                                    Tel: +61 3 8610 3000 Richard Mew - CEO Tel: +44 (0) 1483 282759 Seymour Pierce Ltd Jonathan Wright / Richard Redmayne                             Tel:  +44 (0) 20 7107 8000 This announcement is distributed by Thomson Reuters on behalf of Thomson Reuters clients.
