Drilling Program  NEWS RELEASE TRANSMITTED BY MARKETWIRE  FOR: Rodinia Oil Corp.  TSX VENTURE SYMBOL:  ROZ  April 20, 2011  Rodinia Oil Corp. Confirms Rig Mobilization for Officer Basin Drilling Program  CALGARY, ALBERTA--(Marketwire - April 20, 2011) - Rodinia Oil Corp. ("Rodinia" or the "Corporation") (TSX VENTURE:ROZ) is pleased to announce that Ensign Australia Pty. Limited, a subsidiary of Ensign International Energy Service ("Ensign International") has begun de-mobilizing its heavy triple Rig #16 from the Cooper Basin, South Australia. Ensign International is mobilizing the rig to the Officer Basin in South Australia for Rodinia.  Drilling Program Update   Ensign International's Rig #16 has begun mobilizing for the approximately 2,000 kilometre journey to the Officer Basin to commence drilling of "Mulyawara 1", the first well in Rodinia's exploratory drilling program. Mulyawara 1 is expected to spud in mid-May and drilling is expected to take approximately six weeks.  Mulyawara 1 is located in the northwest corner of PEL 253 (South Australia) and will test a structure of approximately 36.3 square kilometres (per horizon) in size identified on seven seismic lines. This well will target five potential reservoirs, the deepest of which is the aeolian Pindyin sandstone (also called the sub-salt unit). Rodinia has an 80% working interest in this well and prospect and is the operator.  Rodinia's contract with Ensign International includes four firm wells with the option for up to four additional wells in the Officer Basin.  Report by Ryder Scott Company Canada   According to a report (the "Ryder Scott Resource Report") prepared by Ryder Scott Company Canada (independent oil and natural gas reservoir engineers), dated January 12, 2010 and effective December 31, 2009, the unrisked, undiscovered, prospective (recoverable) resource, based on a best (P50) scenario, for Mulyawara 1 is estimated at 2.7 BBbls (gross) of oil.  The Ryder Scott Resource Report on the resource potential of the Officer Basin describes the prospective (recoverable) portion of "Undiscovered Resources", as defined by the Canadian Oil and Gas Evaluation Handbook and does not represent an estimate of reserves. The Ryder Scott Resource Report is compliant with National Instrument 51-101 "Standards of Disclosure for Oil and Gas Activities" ("NI 51-101"). There is no certainty that any portion of the resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.  Prospective resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective resources have both an associated chance of discovery and a chance of development. Prospective resources are presented as unrisked prospective oil resources. The term unrisked means that no geological risk (play risk) has been incorporated in the hydrocarbon volume estimates.  Additional information on the prospective resources can be found at www.sedar.com, in the Long Form Prospectus dated May 20, 2010 filed under Rodinia Oil Corp.
