Exploration geologists are now developing new ore-deposit models to improve the chances of finding such "environmentally friendly" ore bodies. The copper ore bodies mined from 1911 to 1938 at Kennecott, Alaska (now within the Wrangell-St. Elias National Park and Preserve), are examples of potentially environmentally "friendly" ore deposits.
