ABSTRACT:A technical report (the Report) has been prepared for Teck Resources Limited in compliance with National Instrument 43-101 “Standards of Disclosure for Mineral Projects” (NI 43-101) on the Red Dog mining operation (the Red Dog Mine or the Project), located in Alaska. As used in this report, “Teck” refers to Teck Resources Limited or its wholly owned subsidiaries, as applicable. The Report is used in support of Teck’s annual information form (AIF) filing and in support of updated Mineral Resource and Mineral Reserve estimates for the operation. The Red Dog mine currently operates two open pits at Aqqaluk and Qanaiyaq using conventional open pit drill and blast and truck and loader technology. The pits are mined with a TAK-owned and maintained fleet of equipment. Generally, the pit equipment operates at low utilization rates as the mine easily supplies the necessary feed for the mill and concentrator. Open pit designs use geotechnical structural analysis, structural domains based on rock types, and rock mass quality ratings for the principal lithologies. Golder Associates are the engineer of record for the Project and have approved the pit designs. Water inflows that must be managed are as the result of seepage in the Aqqaluk pit, and for both pits, the results of the freshet (spring melt). A two-phase work program is recommended. The first phase should consist of mine site based activities that will result in workflow improvements, and reviews to provide a better understanding of some of the current Project data. The second phase should include additional metallurgical test work, supporting mining studies and exploration activities. The total program is estimated at $310,000.
