VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 28, 2013) - Horn Petroleum Corporation (TSX VENTURE:HRN)("Horn" or the "Company") is pleased to announce its financial and operating results for the three months ended March 31, 2013.

• During the three months ended March 31, 2013, Horn increased its investment in intangible exploration assets by $1.3 million. The majority of the costs incurred during the first three months of 2013 related to Production Sharing Agreement ("PSA") related expenditures and general and administrative costs.
• Efforts are currently focused on making preparations for a seismic acquisition campaign in the Dharoor Valley area 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 well locations.
• As at March 31, 2013, the Company had cash of $6.9 million and working capital of $5.9 million as compared to cash of $9.5 million and working capital of $4.4 million at December 31, 2012.
• Horn continues to investigate potential joint venture partnerships and also is reviewing new venture opportunities in the region.

Horn President and CEO, David Grellman, commented, "We remain very encouraged by the exploratio n 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."

First Quarter 2013 Financial and Operating Highlights

Operating expenses decreased $0.1 million for the three months ended March 31, 2013 due mainly to a reduction in stock option expenses. The reduction in stock option expenses can be attributed to a reduction in the remaining life of the stock options.

Financial income and expense for the three months ended March 31, 2013 and 2012 is made up of the following items:

At March 31, 2013, 53.4 million warrants were outstanding. The Company recorded a $3.6 million gain on the revaluation of warrants for the three months ended March 31, 2013 due to a reduction in the volatility of the shares of Horn combined with a reduction in the remaining life of the warrants.

The foreign exchange gains and losses are the direct result of changes in the value of the Canadian dollar in comparison to the US dollar. The Company's cash holdings are primarily in US and Canadian currency.

The decrease in total assets from December 31, 2012 to March 31, 2013 is the result of a decrease in cash and cash equivalents which is due to operating expenditures and the settlement of accounts payables and accrued liabilities. The increase in net working capital from December 31, 2012 to March 31, 2013 is mainly due to the $3.0 million decrease in current portion of warrant liabilities resulting from the revaluation of warrant liability.

The decrease in cash in three months ended March 31, 2013 is mainly the result of intangible exploration expenditures, operating expenses and the settlement of accounts payable and accrued liabilities.

The Company's consolidated financial statements, notes to the financial statements, management's discussion and analysis for the three months ended March 31, 2013 and the 2012 Annual Information Form have been filed on SEDAR (www.sedar.com) and are available on the Company's website (www.hornpetroleum.com).

Outlook

Based on the encouragement provided by the Shabeel wells, the Company and its partners entered the next exploration period in both the Dharoor Valley and Nugaal Valley PSAs which carry a commitment to drill one well in each block within an additional three year term ending October 2015. The current operational plan is to contract a seismic crew to acquire additional data in the Dharoor Valley block and to hold discussions with the Puntland Government regarding drill ready prospects in the Nugaal Valley block. The focus of the Dharoor Valley block seismic program will be to delineate new structural prospects for the upcoming drilling campaign.

Horn has been in discussions with potential joint venture partners and also is reviewing new venture opportunities in the region.

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.
