Data and Statistics on New York's Mining Resources

On This Page

Mining Data Available from DEC

The Division of Mineral Resources maintains a data management system on mines regulated under the Mined Land Reclamation Law (MLRL.) The MLRL was enacted in 1975. Mines operated and closed prior to that date were not regulated or tracked by the Division. Roughly 5,400 mines are in that system with approximately 2100 active mines and the rest reclaimed since 1975. To assist the Division in the regulation of the extractive mineral industry a database of the mines was created in the early 1980's and significantly upgraded in 2002. This is primarily a regulatory database and does not track any production volumes. All of this data is created and maintained for the use of the Division and as such is covered by a disclaimer regarding the use of this data.

The Division offers mining data in several formats. Listed below are the types of computerized information offered by the Division of Mineral Resources

  • Searchable on-line Mining Database - This system to allows users to generate dynamic queries and save the output either as an Excel based file or in a comma separated value format.
  • Downloadable Mining Database- This is a complete download of the mines record set from the searchable online database in a zipped, .csv formatted file with html metadata.
  • Mineral Mapper- This application is an interactive mapping application of mining locations and oil and gas wells. This tool allows you to zoom in on different locations and review information about the regulated site.
  • Materials Mined in New York- This site provides information on the various material mined in New York and the locations where they are extracted.
  • Mined Land Reclamation Data Summaries- Information on the extractive mineral industry in New York by DEC Region and counties. Summary information on the scope of activity by acreage and mine type.

Data from Mineral Resources

The Division of Mineral Resources is legislatively mandated to regulate the extractive mineral industries. These industries break into two basic programs the mining and the oil and gas programs. The Division collects and maintains in its computer systems extensive data on the regulation of these industries. The Division supplies this information to the public, regulated industries and other governmental agencies through its website. The following statement is the Division's disclaimer on the data we provide:

Downloadable Mining Database

The Division's publicly available dataset of mine information is provided in .csv format. This file can be opened with MS Excel, ESRI ArcGIS, and most database management software (e.g. SQL, Oracle, etc.). To open the file, save (644 KB) to a directory. contains two files: an excel compatible spreadsheet named gismines.csv and a data documentation file named MinesMetaData.html. Unzip/extract and open gismines.csv using a spreadsheet or database application. The documentation file can be viewed directly using any internet browser application. The .csv file is composed of the same data offered through the online searchable database. Please review the disclaimer above on data provided by the NYSDEC Division of Mineral Resources.


This dataset contains information from the Division of Mineral Resources Mined Lands permit files. Please note that:

  1. The dataset contains most mines permitted since 1983 but only a limited number of mines from before 1983.
  2. Coordinate locations are approximate.
  3. The dataset has not been completely error checked. Some errors in location or attribute values may exist.
  4. The dataset may contain multiple points at a single location.
  5. Mines with unknown or grossly incorrect coordinates do not appear in the dataset.

Location Accuracy

The locations in the dataset were obtained from a number of sources. Locations have generally been scaled from USGS 71/2 minute topographic maps provided by the applicant. The location may be either the approximate centroid of the mine or the point where the mine access road enters a public road. This data has not been field-verified but is expected to be within 100 meters of the actual facility. The data should not be used for precise determination of facility buildings, property or mine entrances. It is most useful for determining general locations of mines. All locations are in the NAD 83 datum.
