Item 4. Mine Safety Disclosures.

Our highest priority is the health, safety and well-being of our workforce. We believe that health and safety considerations are integral to, and fundamental for, all other functions in our organization, and we understand that the health and safety of our workforce is critical to our operational efficiency and long-term success. Our global health and safety approach, “Safe Production Matters,” is focused on fatality prevention and continuous improvement through the use of robust management systems, empowering safe work behaviors and strengthening our safety culture.

Our objective is to achieve zero workplace fatalities and to decrease injuries and occupational illnesses. We measure progress toward achieving our objective against regularly established benchmarks, including measuring company-wide Total Recordable Incident Rates (TRIR). Our TRIR (including contractors) per 200,000 man-hours worked was 0.69 in 2020, 0.74 in 2019 and 0.71 in 2018. The metal mining sector industry average per 200,000 man-hours worked reported by the U.S. Mine Safety and Health Administration was 1.81 in 2019 and 1.68 in 2018. The metal mining sector industry average for 2020 was not available at the time of this filing.

Refer to Exhibit 95.1 for mine safety disclosures required in accordance with Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K.
