VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 22, 2012) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE U.S.

Africa Oil Corp. (TSX VENTURE:AOI)(OMX:AOI) ("Africa Oil" or the "Company") is reports that Horn Petroleum Corp. ("Horn Petroleum") announced today that it will sell on a non-brokered private placement basis an aggregate of up to 18.75 million units of Horn Petroleum at a price of $0.80 per unit for gross proceeds of up to $15 million.

Each unit is comprised of one common share and one-half of a share purchase warrant. Each whole warrant is exercisable over a period of two years at a price of $1.20 per share. In the event that Horn Petroleum common shares trade at or above $1.50 for a period of 20 consecutive days, a forced exercise provision will come into effect. A 5% finder's fee may be payable in either cash or units on all or a portion of the private placement.

Net proceeds of the private placement will be used towards Horn Petroleum's ongoing work program in Puntland, Somalia and for general working capital purposes. Shares issued pursuant to the private placement will be subject to a four month hold period. Horn Petroleum will make commercially reasonable efforts to have the warrants posted for trading on the TSX Venture Exchange after the expiry of the hold period.

Africa Oil Corp. is a Canadian oil and gas company with assets in Kenya, Ethiopia and Mali as well as Puntland (Somalia) through its 51% equity interest in Horn Petroleum Corporation.

The East African Rift Basin system is one of the last of the great rift basins to be explored. New discoveries have been announced on all sides of Africa Oil's virtually unexplored land position including the major Albert Graben oil discovery in neighbouring Uganda.

Good quality existing seismic show robust leads and prospects throughout Africa Oil's project areas.
