Ontario Mineral Inventory

The Ontario Mineral Inventory (OMI) database (previously known as the Mineral Deposit Inventory or MDI database) provides an overview of mineral occurrences in the province of Ontario. It contains information on location, geological environment, exploration history of metallic and industrial mineral occurrences, as well as some building stone and aggregate sites. Occurrences are categorized by their status (e.g., producing mine, developed prospect with reserves or resources, mineral occurrence, etc.). When available, current and historical production and resource data also are included.
