Oromin Explorations Ltd.Response letter to Securities and Exchange CommissionSeptember 14, 2012Page 2 of 2
 Item 8. The Company’s conversion from Canadian GAAP to IFRS included the application of the IFRS 1 mandatory exceptions regarding estimates. In accordance with IFRS 1, an entity’s estimates under IFRS at the date of transition to IFRS must be consistent with estimates made for the same date under previous GAAP unless those estimates were in error. The Company’s IFRS estimates as at the transition date are consistent with its Canadian GAAP estimates as at that date. As stated in Note 2 (P) of the Company’s annual financial statements for the year ended February 29, 2012, the Company’s accounting policy regarding estimates is: “...estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and further periods if the review affects both current and future periods.” The application of the above mandatory exception had no material impact on the Company’s financial condition, changes in financial condition and results of operations under accounting treatment specified by IFRS. In other words, the Company’s financial statements as presented under IFRS would have been materially consistent regardless of the application of the above mandatory exception. Item 9. We have obtained a revised report from Ernst & Young LLP (“EYLLP”) set out below as revised Exhibit pages F-40 and F-41. This revised report sets out that EYLLP has performed their audit in accordance with US generally accepted auditing standards (GAAS); that the statements are based on IFRS as issued by the IASB; and that complies with US GAAS standards regarding a description of our going concern uncertainties. We also advise that Oromin Joint Venture Group Ltd. has used IFRS as issued by the IASB from inception. ÐÑÐÑÐÑ We conclude this response with our acknowledgment that the Company is responsible for the adequacy and accuracy in its filings; that staff comments or changes in disclosure in response to staff comments do not foreclose the Commission from taking any action with respect to our filings; and that the Company may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. We trust you will find our response satisfactory. The writer may be contacted as set out in the letterhead. Yours sincerely,
    OROMIN EXPLORATIONS LTD.

EXPLANATORY NOTES In response to comments from the staff of the Securities and Exchange Commission, the Company has amended its Form 20-F Annual Report as follows: 1) We have revised the disclosure in Item 15 “Evaluation of Disclosure Controls and Procedures” to read as set out below, clarifying that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were adequately designed but were noteffective; 2) We have revised our disclosures in Part III to confirm that financial statements included in the Form have been prepared under Part 18 of the Form rather than Part 17, as set out below. 3) We have replaced exhibit pages F-2 and F-3, being the Independent Auditors’ Report of Davidson & Company LLP, with new exhibit pages F-2 and F-3 as set out below, clarifying that Davidson & Company’s audit was conducted in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”), that the consolidated financial statements are in accordance with International Financial Reporting standards as issued by the International Accounting Standards Board, and expanding upon the “Emphasis of Matter” paragraph to comply with PCAOB standards regarding the description of our going concern uncertainties; 4) We have replaced exhibit pages F-40 and F-41, being the Independent Auditors’ Report of Ernst & Young Chartered Accountants on the financial statements of Oromin Joint Venture Group Ltd., a significant equity investee of the Company, with new exhibit pages F-40 and F-41 as set out below, clarifying that Ernst & Young’s audit was conducted in accordance with auditing standards generally accepted in the United States, that the consolidated financial statements are in accordance with International Financial Reporting standards as issued by the International Accounting Standards Board, and revising the final paragraph to comply with US generally accepted auditing standards regarding the description of our going concern uncertainties. AMENDMENTS ITEM 15.
        CONTROLS AND PROCEDURES
 EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company is collected and communicated to management, as appropriate, to allow timely decisions regarding required disclosure. At the end of the period covered by this report, the fiscal year ended February 29, 2012 an evaluation was carried out under the supervision of, and with the participation of, the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operations of the Company’s disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act). Based on that evaluation, taking into account the identification of material weaknesses in internal controls set out in Item 15 “Management’s Report on Internal Control over Financial Reporting”, the CEO and the CFO have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were adequately designed but were not effective in providing reasonable assurance that material information required to be disclosed in the reports that management files and submits under the Exchange Act, is recorded, processed summarized and reported within the time periods specified in the SEC rules and forms. It should be noted that while the Company’s chief executive officer and chief financial officer believe that the Company’s disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that the Company’s disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

INDEPENDENT AUDITORS' REPORT To the Shareholders of 
    Oromin Explorations Ltd. We have audited the accompanying consolidated financial statements of Oromin Explorations Ltd. which comprise the consolidated statements of financial position as at February 29, 2012, February 28, 2011 and March 1, 2010, and the consolidated statements of comprehensive loss, changes in equity and cash flows for the years ended February 29, 2012 and February 28, 2011, and a summary of significant accounting policies and other explanatory information. Management’s Responsibility for the Consolidated Financial Statements Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error. Auditors’ Responsibility Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion. F-2

Opinion In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of Oromin Explorations Ltd. as at February 29, 2012, February 28, 2011 and March 1, 2010 and its financial performance and its cash flows for the years ended February 29, 2012 and February 28, 2011 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. Emphasis of Matter The accompanying consolidated financial statements have been prepared assuming that Oromin Exploration Ltd. will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and has no current source of revenue that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Other Matters We have also audited, in accordance with the standards of the Public Company Accouting Oversight Board (United States), the effectiveness of Oromin Explorations Ltd.’s internal control over financial reporting as of February 29, 2012, based on criteria established in Internal Control – Integrated Frameworkissued by the Committee of Sponsoring Organizations on the Treadway Commission (COSO), and our report dated July 11, 2012 expressed an adverse option on Oromin Explorations Ltd.’s internal controls over financial reporting because of material weaknesses.

Management’s responsibility for the financial statements Management is responsible for the preparation and fair presentation of these financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

Opinion In our opinion, the financial statements present fairly, in all material respects, the financial position of Oromin Joint Venture Group Ltd. as at February 29, 2012 and February 28, 2011 and the results of its operations and its cash flows for the years then ended in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. Emphasis of matter Without qualifying our opinion, we draw attention to note 1 in the financial statements which indicates that the Company has a shareholders’ deficiency of $23,655,109. This condition, along with other matters as set forth in note 1, indicates the existence of a material uncertainty that raises substantial doubt about Oromin Joint Venture Group Ltd.’s ability to continue as a going concern. /s/ Ernst & Young LLP Chartered Accountants
