Exhibit 95.1

Disclosure of Mine Safety and Health Administration (MSHA) Safety Data

BHPs mining operations in the United States are subject to regulation by MSHA under the U.S. Federal Mine Safety and Health Act of 1977 (the Mine
Act). MSHA inspects mines and issues various citations and orders when it believes a violation has occurred under the Mine Act, and it typically 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), which requires certain disclosures by companies operating mines regulated under the Mine Act and which are required to file periodic reports under the U.S Securities Exchange Act of 1934, as amended. The disclosures reflect
only our U.S. mining operations as the requirements of Dodd-Frank do not apply to mines operated outside the United States.

During the year ended
30 June 2017, none of the mines operated by BHP 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 Mine Act or (b) the potential to have such a pattern.

The
information in the table below reflects citations and orders issued by MSHA inspectors to the relevant BHP site during the year ended 30 June 2017. This data may not match or reconcile with the data MSHA maintains on its public website.

In evaluating this information, consideration should be given to factors such as: (a) the number of citations and orders may vary depending on the size,
nature of operations and operational status of the mine, (b) the number of citations issued may vary from inspector to inspector and mine to mine, and (c) citations and orders may be contested and appealed, a process which may result in a
reduction in severity and amount, or they might be dismissed.
