Exhibit 99.12

Dodd-Frank Act Disclosure of Mine Safety and Health Administration Safety Data

Barrick Gold Corporation (Barrick) is committed to the health and safety of its employees and in providing an incident free
workplace. Barrick maintains a comprehensive health and safety program that includes extensive training for all employees and contractors, site inspections, emergency response preparedness, crisis communications training, incident investigation,
regulatory compliance training and process auditing.

Barricks U.S. mining operations are subject to Federal Mine Safety and Health
Administration (MSHA) regulation under the U.S. Federal Mine Safety and Health Act of 1977 (FMSH Act). MSHA inspects Barricks mines on a regular basis and issues various citations and orders when it
believes a violation has occurred under the FMSH Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation.

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act
(Dodd-Frank Act), which requires certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934 that operate mines regulated under the FMSH Act. The disclosures reflect Barricks
U.S. mining operations only as the requirements of the Dodd-Frank Act do not apply to Barricks mines operated outside the United States.

In addition, as required by the reporting requirements regarding mine safety included in section 1503(a)(2) of the Dodd-Frank Act, for the
year ended December 31, 2014, none of the mines operated by Barrick received written notice from MSHA of (a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and
substantially contributed to the cause and effect of mine health or safety hazards under section 104(e) of the FMSH Act or (b) the potential to have such a pattern.

The information in the table below reflects citations and orders MSHA issued to Barrick during the year ended December 31, 2014, unless
otherwise noted, as reflected in Barricks records. The data in Barricks system may not match or reconcile with the data MSHA maintains on its public website. In evaluating this information, consideration should also be given to factors
such as: (i) the number of citations and orders may vary depending on the size and operation of the mine, (ii) the number of citations issued may vary from inspector to inspector and mine to mine, and (iii) citations and orders may be
contested and appealed, and in that process, may be reduced in severity and amount, and may be dismissed.

|(3) | Represents the total number of orders issued, which represents a failure to abate a citation under section 104(a) within the period prescribed by MSHA. This results in an order of immediate withdrawal from the area of
the mine affected by the condition until MSHA determines that the violation has been abated.

|(4) | Represents the total number of citations and orders issued by MSHA for unwarrantable failure to comply with mandatory health or safety standards. These types of violations could significantly and substantially
contribute to a serious injury; however, the conditions do not cause imminent danger (see note 6 below).

independent adjudicative agency established by the FMSH Act that provides administrative trial and appellate review of legal disputes arising under the FMSH Act. These cases may involve, among other questions, challenges by operators to citations,
orders and penalties they have received from MSHA or complaints of discrimination by miners under Section 105 of the FMSH Act. The following provides additional information of the types of proceedings that may be brought before the Commission:
