(1) Based on the Schedule 14D-9F filed on July 5, 2013 by the Issuer, as of July 3, 2013, there were 137,368,218 common shares of the Issuer outstanding. On August 9, 2013 the Reporting Person took up 2,792,989 common shares of the Issuer validly deposited under the Varied Offer, representing approximately 2.03% of the outstanding common shares of the Issuer (on a non-diluted basis). Together with, the 96,982,912 common shares of the Issuer previously owned by the Reporting Person, this represents a total of 99,775,901 common shares of the Issuer, or approximately 72.6% of the outstanding common shares of the Issuer (on a non-diluted basis). This amount excludes deficient tenders to the Varied Offer that may yet be rectified and additional shares of the Issuer that may be tendered pursuant to the Notice of Guaranteed Delivery process.

(2) The Reporting Person previously reported on its Schedule 13D Amendment No. 3 that it owned 97,684,888 common shares of the Issuer, however, 701,976 of those shares represented deficient tenders. The common shares of the Issuer owned by the Reporting Person minus the 701,976 common shares that were deficiently tendered was 96,982,912 common shares of the Issuer.

This Amendment No. 4 (this “Amendment”) amends the Schedule 13D filed by Teranga Gold Corporation, a corporation incorporated under the laws of Canada (the “Reporting Person”), with the Securities and Exchange Commission (the “SEC”) on December 8, 2010 (as amended on June 3, 2013, July 24, 2013 and August 8, 2013, the “Schedule 13D”), and is being filed by the Reporting Person with respect to the common shares (the “Common Shares”) of Oromin Explorations Ltd., a corporation incorporated under the laws of the Province of British Columbia, Canada (the “Issuer”). This Amendment supplements or amends the Schedule 13D as set forth herein. Capitalized terms used herein and not defined shall have the meaning attributed to them in the Schedule 13D.

Item 4.	Purpose of Transaction.
Item 4 is supplemented as follows: On August 9, 2013, the Reporting Person took up an additional 2,792,989 Common Shares validly deposited under the Varied Offer, representing approximately 2.03% of the outstanding Common Shares (on a non-diluted basis). The transaction took place pursuant to the Varied Offer and not through the facilities of any stock exchange or any other marketplace. The 2,792,989 Common Shares acquired by the Reporting Person pursuant to the Varied Offer were acquired for consideration of 0.60 of a Teranga Share for each Common Share. Except as otherwise set forth in this Item 4, the Reporting Person currently has no plans or proposals of the type that would be required to be disclosed pursuant to this Item 4, although the Reporting Person may from time to time consider pursuing or proposing any or all of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.	Interest in Securities of the Issuer.
(a) – (b) The information set forth on the cover page of this Schedule 13D is incorporated herein by reference. (c) – (e) Not applicable. Additional Information This Amendment does not constitute an offer to buy or an invitation to sell, or the solicitation of an offer to buy or invitation to sell, any securities of the Reporting Person or the Issuer (including in any state where the Varied Offer is not permitted). The Reporting Person has filed with the SEC a registration statement on Form F-80 and a tender offer statement on Schedule 14D-1F, each of which includes the offer and take-over bid circular, and other documents and information. U.S. INVESTORS AND U.S. SECURITY HOLDERS OF THE ISSUER ARE URGED TO READ THESE DOCUMENTS AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC, BEFORE MAKING ANY INVESTMENT DECISION WITH RESPECT TO THE PROPOSED TRANSACTION BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED TRANSACTION. U.S. Investors and U.S. security holders of the Issuer may obtain these documents free of charge at the SEC’s website at www.sec.gov. In addition, the documents filed with the SEC by the Reporting Person can be obtained free of charge by directing such request to the Reporting Person’s Information Agent, or at the Reporting Person’s website at www.terangagold.com.
