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 mlDOS.zip (644 KB) to a directory. mlDOS.zip contains two files: an excel compatible spreadsheet named gismines.csv and a data documentation file named MinesMetaData.html. Unzip/extract mlDOS.zip 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 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.
