Pauling Limonite Mine
Pawling, New York
The Pauling Limonite Mine is near Pawling, 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 site was first discovered in 1825 by An Unknown Prospector. The Pauling Limonite Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1870 to 1888. Mine operations consist of surface and underground workings extending 5.26 hectares (12.99 acres). There is one known shaft. Subsurface depth reaches a maximum of 40 meters (130 feet) and extends 366 meters (1,200 feet) in length. The ore mined is composed of limonite. The ore body is described as tabular shaped 731 meters (2,400 feet) long and 106 meters (350 feet) thick. The host rock in this area is schist from the Lower Ordovician epoch 485.40 to 470.00 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.
