| ABSTRACT: | Mr. Rodrigo Alves Marinho, P.Geo., and Mr. Michael Nelson, F.AusIMM., prepared this technical report (the Report) for Teck Resources Limited (Teck) based on the 2016 Feasibility Study (FS2016) in respect of Phase 2 (QB2) of the Quebrada Blanca mining operation (the Project), located in Chile’s Región de Tarapacá. The Project owner is Compañia Minera Teck Quebrada Blanca S.A. (CMTQB). The shareholders of this company are Teck Resources Limited (Teck) which has an indirect 76.5% holding and is the Operator of the Project; Inversiones Mineras S.A (IMSA) which is a private Chilean company that has a 13.5% holding; and Empresa Nacional de Minería (ENAMI), the Chilean State-run minerals company, which has a 10% holding. Teck through its holdings generally controls the operation. QB2 is not subject to any royalties held by third parties. The Report supports Teck’s 2016 annual information form (AIF) filing and updated Mineral Resource and Mineral Reserve estimates. Mining operations will continue to use open pit methods, and conventional truck-and-shovel operations. From an operational standpoint, QB2 represents a continuation of the existing supergene mining activities; however, there are significant differences between the two operations, such as the significant increase in the ultimate pit depth, the change in rock type from enriched supergene to hypogene, and the proposed increase to the mining extraction rate. The geotechnical domain model for the feasibility study was based on work by E-Mining Technology S.A. in 2011 and updates by Piteau Associates (Piteau) from studies completed in 2015 and 2016. The 2016 final design pit was then evaluated by Piteau using all available geotechnical data into the kinematic and overall global stability analyses. The majority of issues identified were considered operationally manageable. | |
