The GeologyOntario search tool allows you to search 5 databases: the Ontario Assessment File Database (OAFD), the Abandoned Mines Information System (AMIS) database, the Ontario Drill Hole Database (ODHD), the Mineral Deposit Inventory (MDI) database and the Ontario Geological Survey Publications (PUB) database. Please read the descriptions for more information on each database.
The Publications database (PUB) can be viewed as a list. The list includes all reports, data and maps, with links to download the information. The page can be searched (within the web browser) for publication number, name, author, year, area, NTS scale (where applicable).
NOTE: The page contains a large amount of information (18 000+ records) and will take time to load completely. The OAFD, AMIS, ODHD and MDI information is not included in this list.
The following databases can be downloaded: OAFD Download OAFD (ZIP), AMIS Download AMIS (ZIP), ODHD Download ODH (ZIP), and MDI Download MDI (ZIP). The downloadable files may include a Microsoft® Excel® spreadsheet or Access® database and GIS files in shapefile format.
Geoscience and mineral exploration data can be viewed spatially using the OGSEarth Opens in a new window application.
