Rare Element’s Bear Lodge Project area consists of 499 unpatented lode claims on
9,000 acres and includes all known significant rare earth occurrences in the Bear
Lodge Mountains. The property hosts deposits of rare earths, as well as the
Sundance Project gold deposits. There are no other known significant occurrences of
rare earths in the region surrounding the Bear Lodge Mountains.
A number of precious metal mines and prospects are hosted in, and associated with,
either Tertiary intrusions or Precambrian crystalline rocks in the surrounding Black
Hills region of South Dakota and Wyoming. Gold deposits of Precambrian age,
typified by the Homestake Mine near Lead, South Dakota, have been the dominant
precious-metal producers in the northern Black Hills for more than 100 years. More
recently, intrusive-hosted systems of Tertiary age in the northern Black Hills of South
Dakota have produced several million ounces of gold and contain significant
remaining resources. These younger deposits include Gilt Edge, Richmond Hill,
Annie Creek, and Foley Ridge in South Dakota, and the Mineral Hill and Sundance
(and Bear Lodge) deposits in Wyoming (Figure 23.1).
