VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/20/12 -- Horn Petroleum Corporation (TSX VENTURE:HRN) ("Horn" or the "Company") is pleased to announce its results for the third quarter of 2012.

--  During the nine months ended September 30, 2012, Horn increased its
    investment in intangible exploration assets by $30.0 million. The
    majority of the costs incurred during 2012 related to drilling the
    Shabeel-1 and Shabeel North-1 exploration wells in the Dharoor Valley
    block. The remaining expenditures are PSA related expenditures and
    general and administrative costs. The Company and its Partners fulfilled
    the initial exploration period work commitments under the Dharoor Valley
    and Nugaal Valley PSAs with the drilling of the Shabeel wells.

--  While the Company was disappointed that the first two exploration wells
    in Puntland (Somalia) did not flow oil, the Company remains highly
    encouraged that all of the critical elements exist for oil
    accumulations. Horn recently completed demobilization of the drilling
    rig and associated equipment and both well sites have been restored to
    original condition.

--  Horn and its partners have entered into the next exploration period in
    both the Dharoor Valley and Nugaal Valley PSAs which each carry a
    commitment to drill one exploration well in each block by October 2015.

--  Efforts are now focused on making preparations for a seismic acquisition
    campaign in the Dharoor PSA which will include a regional seismic
    reconnaissance grid in the previously unexplored eastern portion of the
    basin as well as prospect specific seismic to delineate a drilling
    candidate in the western portion of the basin where an active petroleum
    system was confirmed by the recent drilling at the Shabeel-1 and Shabeel
    North-1 locations.

--  Operating expenses of $0.5 million were recorded during the third
    quarter of 2012 ($1.6 million during the nine months ended September 30,
    2012). These were offset by finance income of $23.0 million during the
    third quarter of 2012 ($9.0 million during the nine months ended
    September 30, 2012). Finance income primarily relates to fair market
    value adjustments of the Company's warrant liabilities. These fair
    market value adjustments are performed as the Company has an obligation
    to issue shares for a price (denominated in Canadian dollars) that is
    not fixed in the Company's functional currency (United States dollars).

--  As at September 30, 2012, the Company had cash of $16.1 million and
    working capital of $12.4 million as compared to cash of $27.6 million
    and working capital of $25.9 million at December 31, 2011. The Company's
    liquidity and capital resource position has been reduced during 2012
    primarily due to expenditures incurred on the drilling of the Shabeel-1
    and Shabeel North-1 exploration wells offset partially by the non-
    brokered private placement which raised CAD$15.0 million in June 2012.

--  Horn continues to investigate potential joint venture partnerships and
    also is reviewing new venture opportunities in the region.

--  The Board has approved granting 2,820,000 incentive stock options to
    certain directors, officers and other eligible persons of the Company.
    The options will have a three year term, vesting provisions consistent
    with the existing outstanding options, and will be priced at $0.32 per
    share (or the closing price on November 21, 2012 if higher).

Horn President and CEO, David Grellman, commented, "We remain very encouraged by the exploration potential of our Jurassic rift basins in Puntland. We have committed to the next exploration phase in both PSAs and plan to aggressively explore both areas to confirm this potential. We are also optimistic that the political progress in Somalia will continue and allow oil and gas exploration in the region to expand."

Horn holds a 60% working interest in the Dharoor and Nugaal Valley blocks and is the operator. The other partners in the blocks are Range Resources (20%) and Red Emperor (20%). Africa Oil Corporation holds an approximate 45% equity interest in Horn.
