 | | Red Dog lead/zinc/silver mine is in the De Long Mountains, western Brooks Range, Alaska, 145km north of Kotzebue. |
 | | Red Dog mined 3.1Mt of ore in 2005, grading 21.7% zinc and 5.6% lead, with an output of 568,000t of zinc and 102,300t of lead that contributed C$325m to Teck Cominco’s operating profits. |
 | | Red Dog consists of four separate deposits – Main, Aqqaluk, Paalaaq and Qanaiyaaq – that are hosted by fl, siliceous shale and chert of the Mississippian-Pennsylvanian Kuna Formation, and recent exploration has identified further deposits at Su-Lik and Arjarraaq, a few kilometres away. |
