Mine Overview
The Century Lode Claim is near Hill City, South Dakota. Historically the site has been associated with the Hill City Mining District which is now part of the Black Hills National Forest. The Century Lode Claim was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. The ore mined is composed of cassiterite, spodumene and amblygonite with waste material consisting primarily of microcline, quartz and albite. The ore is found in dikes 243 meters (800 feet) long and 15 meters (50 feet) wide. Associated rock in this area is pegmatite from the Neoproterozoic era 1.00 to 0.54 billion years ago. The Black Hills of the Interior Plains characterize the geomorphology of the surrounding area.

Footnotes
* Mine bounds on map indicate the general area that a mine occupies. For an detailed map, refer to the overseeing BLM field office.
** The mine central point is based on an average of the mine's bounding box(es) and does not necessarily fall on the claim itself.
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.
