Beekman Limonite Mine

Beekman, New York

41.6138°N 73.7117°W

Mine Overview

The Beekman Limonite Mine is near Beekman, New York. Historically the site has been associated with the Fishkill Belt Mining District which is now part of the Appalachian National Scenic Trail. The Beekman Limonite Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1870 to 1889. Mine operations consist of surface workings extending 0.13 hectares (0.32 acres). There is one known shaft. The ore mined is composed of limonite. The ore is found in pods 152 meters (500 feet) long, 91 meters (300 feet) wide, and 27 meters (89 feet) thick. 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.
