Glendale Gp Beryllium Prospect
Keystone, South Dakota
The Glendale Gp Beryllium Prospect is near Keystone, South Dakota. Historically the site has been associated with the Keystone Mining District which is now part of the Black Hills National Forest. Preliminary development has taken place such as surface trenching, adits, shafts, drill holes, geophysics, geochemistry, or geological mapping. Enough data has been gathered to estimate grade and tonnage. Information from 1978 associates the ore with pegmatite of unknown dimensions. The Black Hills of the Interior Plains 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.
