Cover: Achieving meaningful engagement with key stakeholders in host communities is increasingly important for Kennecott Minerals, as operating properties transition to closure. This is being accomplished through community based partnerships and the formation of community advisory groups to facilitate interactive dialogue with key constituencies. Kennecott Minerals is committed to aligning sustainable development initiatives with core business practices to create long term value for the company and future generations.
