Mine Overview

The Champion Property 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. The site was first discovered in 1939 by Mr. Champion. The Champion Property was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. Mine operations consist of surface workings. There is one known shaft. Subsurface length extends a maximum of 1 meters (4 feet). The ore mined is composed of beryl, feldspar and mica with waste material consisting primarily of spodumene and quartz. The ore is found in dikes 36 meters (120 feet) long and 7 meters (25 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.

Understanding Claim Ownership

We receive lots of emails from people who find their name or a relative’s name on our site and want to know if this means they have some right to the land listed under that name.
Understanding BLM Administrative Areas

Whether it is filing a mine or researching one, the administering BLM office is going to be the definitive source.
Understanding Location Data

Mine handled by the Bureau of Land Management are not mapped by latitude and longitude, instead, these mines harken back to the Public Land Survey System.
Understanding Townships

A “township” can refer to two different things. Both are part of the PLSS measurement system but have different uses.
