Item 4. Mine Safety Disclosures.

Our highest priority is the health, safety and well-being of our workforce. We also work to promote safety with our suppliers and in the communities where we operate. We believe health and safety considerations are integral to, and fundamental for, all other functions in our organization, and we understand the health and safety of our workforce is critical to our operational efficiency and long-term success. Our global health and safety strategy, “Safe Production Matters,” is focused on fatality prevention, eliminating systemic root causes of incidents and continuous improvement through robust management systems, which are supported by leaders empowering our teams to work safely. Our global safety strategy across all levels of the organization is captured in our Fatal Risk Management

(FRM) program. The goal of our FRM program is to achieve zero workplace fatalities by strengthening preventive measures and raising awareness of fatal risks and the measures necessary to mitigate them. The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this quarterly report on Form 10-Q.
