Crown Point Claims
The Crown Point Claims are near Pony, Montana. Historically the area has been associated with the Potosi Mining District which is now part of the Beaverhead National Forest. The Crown Point Claims is a underground mining operation. The ore mined is composed of cerargyrite, tetrahedrite and huebnerite with waste material consisting primarily of pyrite. The ore body extends 1.52 meters (4.99 feet) thick. Associated rock in this area is quartz monzonite from the Upper Cretaceous epoch 100.50 to 66.00 million years ago. The Northern Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area.

1 World-class significance is determined by total endowment of the contained commodity. This includes all past production and remaining reserves. Each commodity is considered separately and commodities cannot be combined to arrive at a significant size. The tonnage thresholds are from the mine model grade-tonnage studies. As of June 2008, many entries were classified as significant under less strict rules.
