Exploration Throughout 2012, exploration efforts were carried out around the world by our nine regional offices. Expenditures  of $102 million in 2012 were focused on copper, zinc and gold opportunities. Exploration plays three critical roles at Teck: discovery of new orebodies through early stage exploration and acquisition;  pursuit, evaluation and acquisition of development opportunities; and delivery of geoscience solutions and services to  create value at our existing mines.  Our copper exploration is focused on porphyry copper deposits and, during 2012, we drilled several porphyry copper  projects in Canada, Chile, Mexico, Peru, Turkey and Namibia. In addition to our 100% owned projects, several resource  stage joint venture projects advanced in 2012, including Zafranal in Peru, Haib in Namibia and La Verde in Mexico.  Significant exploration work was focused in and around our existing operations and advanced projects in 2012. At  our Highland Valley Copper Operations in Canada we successfully completed ground geophysical surveys and target  definition drilling adjacent to the historical Bethlehem pits, outlining some near-surface and copper mineralization. At  our Quebrada Blanca Operations in Chile, we drilled high-quality targets within 10 kilometres of the existing mine and  at our Relincho project in Chile we made new discoveries within 2 kilometres of the current pit design. In 2013, we plan  to drill copper projects in Canada, Peru, Chile, Namibia and Turkey and aggressively explore around our existing operations. Zinc exploration remains focused on three areas: the Red Dog mine district in Alaska, northeastern Australia, and  Ireland. In both Alaska and Australia, the target type is a large, high-grade, sediment-hosted deposit similar to major  world-class deposits such as Red Dog in Alaska and Century or McArthur River in Australia. In 2012, we undertook  approximately 4,000 metres of exploration drilling on the Noatak project, where we have identified multiple high-quality  targets near our existing Red Dog mine. We also conducted exploration drilling for zinc in northeastern Australia and  in Ireland, where the target is a large high-grade deposit similar to the producing Navan mine. Drill programs will  continue in all three regions in 2013. In addition to exploring for copper and zinc, we are exploring for, and looking to partner in, new gold opportunities.  Our plan is to explore, find and advance gold resources through targeted exploration activity in select jurisdictions.  Once an opportunity has been recognized, the strategy is to optimize that opportunity or asset through further definition  drilling and engineering studies, then capture value through periodic divestitures. Our current exploration efforts and  drill testing for gold are primarily focused in Turkey, Canada, Chile, Peru and Colombia. In 2012, we had encouraging  results from TV Tower in Turkey, which is a joint venture with Pilot Gold, and we expect this to progress towards  a resource estimate in 2013. Our 100% Demir and 60% Halilaga gold projects, also in Turkey, moved towards the  resource estimate stage in 2012.  Generations 51
