The Abandoned Mines information system (AMIS) is a database containing information on known abandoned mine sites and mine hazard features located on both Crown and privately held lands within the province of Ontario. This includes sites that are abandoned, may possibly be in production or may be covered by a closure plan. It also includes sites under Mining Act, Aggregate Resources Act and Federal jurisdictions.
This database is current to November 30, 2016.
The GeologyOntario application provides access to MDI database through a quick and effective search engine. Searches can be done by using simple keywords or by using focused searches using Boolean operators. Keywords can include the abandoned mine id, mine name, jurisdiction, and geographic area (NTS, township). An overview and description of the search types including Boolean can be found in the Help Me reference.
The AMIS database can be downloaded from the GeologyOntario application. It is available as a packaged product provided in 2 formats: 1) a tabular spreadsheet (Microsoft® xls) format and 2) a geospatial GIS (ESRI® shapefile) format.
The AMIS sites and features data found on our OGSEarth page can also be viewed in Keyhole Markup Language (KML) format using Google Earth Opens in a new window or other applications compatible with KML. Further database information and metadata is found within the download package.
AMIS sites and features can also be viewed using ArcGIS online.
