The Company’s presentation is furnished herewith as Exhibit 99.1 and is incorporated by reference herein. The presentation has also been posted to the Company’s website – www.magellanpetroleum.com. Such material may be presented to investors in the future.

The information in this Item 7.01, including Exhibit 99.1, is being furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section and shall not be deemed incorporated by reference into any registration statement or other document filed pursuant to the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

Forward Looking Statements

Statements in this presentation which are not historical in nature are intended to be, and are hereby identified as, forward-looking statements for purposes of the Private Securities Litigation Reform Act of 1995. These statements about Magellan and Magellan Petroleum Australia Limited (“MPAL”) may relate to their businesses and prospects, revenues, expenses, operating cash flows, and other matters that involve a number of uncertainties that may cause actual results to differ materially from expectations. Among these risks and uncertainties are the following: the ability of Magellan and Santos to complete and implement the terms of the Santos asset swap/sales agreement and gas sales contract, including securing the customary approvals necessary to complete the asset swap, the future outcome of the negotiations by Santos with its customers for gas sales contracts for the remaining uncontracted reserves in the Amadeus Basin, the production volume at Mereenie and whether it will be sufficient to trigger the bonus amounts provided for in the Santos asset swap/sales agreement, the ability of the Company to successfully develop its existing assets, the ability of the Company to secure gas sales contracts for the uncontracted reserves at Dingo, the ability of the Company to implement a successful exploration program, pricing and production levels from the properties in which Magellan and MPAL have interests, the extent of the recoverable reserves at those properties, the profitable integration of acquired businesses, including Nautilus Poplar LLC, the likelihood of success of the drilling program at the Poplar Fields by the Company’s new farm-in partner, VAALCO Energy, and the results of the ongoing production well tests in the U.K. In addition, MPAL has a large number of exploration permits and faces the risk that any wells drilled may fail to encounter hydrocarbons in commercially recoverable quantities. Any forward-looking information provided in this report should be considered with these factors in mind. Magellan assumes no obligation to update any forward-looking statements contained in this report, whether as a result of new information, future events or otherwise. Any forward-looking information provided in this report, including in the presentation furnished as Exhibit 99.1, should be considered with these factors in mind. The Company assumes no obligation to update any forward-looking statements contained in this report, whether as a result of new information, future events or otherwise.

The following exhibit is furnished herewith:
