Amenia Limonite Mine

Amenia, New York

41.8527°N 73.5603°W

Mine Overview

The Amenia Limonite Mine is in Amenia, New York. Historically the site has been part of the New York Salisbury Iron Mining District. The site was first discovered in 1825 by An Unknown Prospector. The Amenia Limonite Mine was closed at the time of data entry with no known plans to re-open. Mine operations consist of surface workings extending 3.72 hectares (9.18 acres). There is one known shaft. The ore mined is composed of limonite and siderite. The ore body is described as tabular shaped 762 meters (2,500 feet) long, 121 meters (400 feet) wide, and 35 meters (114 feet) thick. The Taconic Section of the Appalachian Highlands characterize the geomorphology of the surrounding area.

Notes

TOPO SHOWS TWO SMALL PONDS AND ONE LARGE POND, THE NORTHERN PART OF WHICH IS THE PALMER PIT OF THE AMENIA MINE, AND THE SMALLER SOUTHERN PART IS THE GRIDLEY MINE PIT (HARTFORD SHEET, NO. 54 ). THE PALMER PIT IS 700 FEET LONG NORTH-SOUTH, 200 FEET WIDE EAST-WEST, AND 115 FEET DEEP. OF THE TWO SMALL PONDS ARE THE WEED MINE WORKINGS. EACH PIT IS ABOUT 400 FEET LONG NORTH-SOUTH, 150 FEET WIDE EAST-WEST, AND ABOUT 20 FEET DEEP.

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.
