The Quebrada Blanca Phase 2 (QB2) Project is one of the world’s largest undeveloped copper resources. When complete, QB2 will be a premier asset, with low operating costs, an initial mine life of 28 years, and significant potential for further growth. Construction of QB2 was sanctioned by the project partners in December 2018. First copper production is planned for the second half of 2021.
QB2 incorporates extensive environmental measures, including the first large-scale use of desalinated seawater for mining in the Tarapacá Region of Chile, in place of freshwater use. The QB2 project has also consulted extensively with local communities and will continue to work cooperatively with stakeholders throughout the life of the project.
Teck holds an indirect 60% interest in Compañía Minera Teck Quebrada Blanca SA ("QBSA") which owns QB2. Sumitomo Metal Mining Co., Ltd. and Sumitomo Corporation together have a collective 30% indirect interest in QBSA. ENAMI, a Chilean state agency, has a 10% non-funding interest in QBSA.
