This Amendment No. 5 amends the original Schedule 13D and its Amendments No. 1, No. 2, No. 3 and No. 4 (together, “Schedule 13D”) previously filed by Red Mountain Resources, Inc. (“Red Mountain”), Black Rock Capital, Inc. (“Black Rock”) and Alan W. Barksdale (“Barksdale”) (collectively herein referred to as the “Reporting Persons”) with respect to ownership of the common stock, par value $0.001 per share (“Common Stock”), of Cross Border Resources, Inc., a Nevada corporation (the “Issuer”). Unless set forth below, all previous Items are unchanged. Capitalized terms used herein which are not defined herein have the meanings given to them in the Schedule 13D, as amended, previously filed with the SEC.

The percentage of beneficial ownership calculation reflected in this Schedule 13D is based upon 16,151,946 shares of Common Stock outstanding as of March 9, 2012, as set forth in the Issuer’s Annual Report on Form 10-K filed with the SEC on March 15, 2012.

Item 4 of the Schedule 13D is hereby amended in its entirety to read as follows:

The Reporting Persons purchased the Common Stock for investment purposes. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Common Stock at prices that would make the purchase or sale of Common Stock desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Common Stock on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

On April 23, 2012, Red Mountain, the Issuer and certain of the Issuer’s officers entered into an Agreement (“Settlement Agreement”), the terms of which are discussed in an Information Statement to Stockholders on Schedule 14f-1 filed with the Securities and Exchange Commission on April 27, 2012. Pursuant to the Settlement Agreement, Mr. Barksdale was appointed to the Issuer’s board of directors, effective on May 8, 2012. As a member of the Issuer’s board of directors, Mr. Barksdale may directly or indirectly influence the management and policies of the Issuer, including changes to the Issuer described in subsections (a) – (j) of Item 4 of Schedule 13D.

Except as set forth above, the Reporting Persons do not have specific plans or proposals at this time that would result in a change to the Issuer as set forth in subsections (a) – (j) of Item 4 of Schedule 13D. The Reporting Persons plan to evaluate their investment in the Issuer on a continuing basis, and in connection with such evaluation the Reporting Persons may in the future upon due consideration of all relevant factors take certain actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the Issuer’s board of directors regarding the events discussed herein, engaging in discussions with third parties about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure or operations of the Issuer, or changing their intention with respect to any and all matters referred to in Item 4.
