Ogdensburg, New Jersey

41.0840°N 74.6037°W

Mine Overview

The Stirling Zinc Mine is in Ogdensburg, New Jersey. Historically the site has been part of the Franklin-Sterling Hill Mining District. The site was first discovered in 1840. The Stirling Zinc Mine was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. Mine operations consist of underground workings. Underground features include 1 adit and 3 inclines. The mining method is horizontal cut and fill with waste rock. Mine capacity in 1983 was 440 mt ore/day with a production unit cost of 41.03 $/mt ore. The ore body is irregularly shaped 914 meters (2,998 feet) long, 533 meters (1,748 feet) wide, and 3 meters (9 feet) thick. The Middle 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.
