Vancouver, B.C. – Teck Resources Limited (TSX: TECK. A and TECK. B, NYSE: TECK (“Teck”) announced today that the Teck Carmen de Andacollo union, which represents 473 employees of Teck Carmen de Andacollo Operations (CdA) in Chile, has ratified a new 36-month collective agreement. The benefits of the agreement will enter into force on 5 December 2019 and CoA`s activities have resumed. In total, 56% of our workforce is unionized. Table 20 provides a list of collective agreements for unionized employees of our major companies (including Antamina). In 2019, collective agreements expired at Line Creek, Coal Mountain, Quebrada Blanca and Carmen de Andacollo. At the end of their collective agreements, a collective agreement was signed in 2019 with two unions at Carmen de Andacollo (CdA) and one union at Quebrada Blanca.

In 2019, a strike took place at CdA, which lasted 52 days and ended with the signing of a new collective agreement. Coal Mountain`s collective agreement was extended by one year due to the company`s maintenance and upkeep, the start of collective bargaining at Line Creek and the end of the year. We will ensure that our minimum draw times exceed or exceed the labour standards set out in the labour standards in force. Minimum time limits for setting may also be laid down in collective agreements. In order to ensure that there is no harassment against union members, we have global or location guidelines and non-discrimination measures specific to each collective agreement.
