Intial Nickel-Copper Copper Occurrence
The Intial Nickel-Copper Copper Occurrence is near Limestone, Montana. Historically the site has been associated with the Stillwater Mining District which is now part of the Custer National Forest. The site was first discovered in 1883 by Jack Nye, Jimmy And Jonas Hedges. Ore mineralization has been found at this location and the size of the deposit is estimated to be small, however the precise grade, tonnage, and extent of the mineralization are not known. There has been no production and little to no activity other than routine claim maintenance since the mineral discovery. Mine operations consist of underground workings extending 0.20 hectares (0.50 acres). There is one known shaft. The ore mined is composed of pyrrhotite, pentlandite and chalcopyrite with waste material consisting primarily of plagioclase and magnetite. The ore body is massive and disseminated in form of unknown dimensions. The host rock in this area is hornfels. The Middle Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area.

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