Mitchell Nickel Sulfide Mine

Goshen, Connecticut

41.8458°N 73.2626°W

Mine Overview

The Mitchell Nickel Sulfide Mine is near Goshen, Connecticut. Historically the site has been part of the Mount Prospect Mining District. The Mitchell 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 ilmenite, chalcopyrite and magnetite with waste material consisting primarily of olivine, biotite and hypersthene. Data from 1982 show the ore was formed by replacement processes of unknown dimensions. Associated rock in this area is diorite 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.

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.
