Buck Nickel Sulfide Mine
The Buck Nickel Sulfide Mine is near Bantam, Connecticut. Historically the site has been part of the Mount Prospect Mining District. The Buck Nickel Sulfide Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1835 to 1837. Production size when active was considered to be small. The ore mined is composed of magnetite, pentlandite and hematite with waste material consisting primarily of clinopyroxene, hypersthene and plagioclase. Data from 1982 show the ore was formed by replacement processes of unknown dimensions. The mineralization at this location is from the Lower Devonian epoch 419.20 to 393.30 million years ago. The New England Upland Section of the Appalachian Highlands 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.
