Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On or about March 11, 2015, Newmont Mining Corporation (the “Company” or “Newmont”) provided its stockholders with the Company’s 2015 Proxy Statement, dated March 5, 2015, for its Annual Meeting of Stockholders to be held on April 22, 2015 (the “Proxy Statement”). Subsequent to that date, there was a development relating to the biographical and independence information with respect to director nominee Alberto Calderón. Mr. Calderón’s biographical information in the Proxy Statement indicates that he serves as a non-employee director of Orica Limited (“Orica”). On March 23, 2015, Orica announced that Mr. Calderón has been appointed to serve as interim managing director and chief executive officer, while Orica conducts an international search to select a permanent managing director and chief executive officer. As disclosed in the Proxy Statement, Orica provides certain chemical and explosive supplies and services to Newmont. As a result, the Corporate Governance and Nominating Committee has reassessed Mr. Calderón’s independence designation while serving in the interim role and determined that, during the duration of his interim service as Orica’s chief executive officer, Mr. Calderón will not be considered to be an independent director. As a result, for so long as Mr. Calderón is not considered to be independent, he will not be a member of the Audit Committee, Compensation Committee or Corporate Governance and Nominating Committee of the Newmont Board of Directors (the “Board”). During the duration of his interim executive appointment at Orica, it is expected that Mr. Calderón will serve on the Board’s Safety and Sustainability Committee. Upon completion of his interim role at Orica, the independence determination and committee appointment will be reassessed by the Corporate Governance and Nominating Committee. Currently, no other financial, personal or other relationships are known to exist that would influence or impair Mr. Calderón’s independence. Based on the foregoing, seven of the nine director nominees have been affirmatively determined by the Board to be independent. The Notice of Meeting, Proxy Statement and Annual Report are available at www.envisionreports.com/nem.
