The Ministry of Northern Development and Mines is releasing an updated version of the Mineral Deposit Inventory Version 2 (MDI2). This database is an inventory of mineral deposits in the province of Ontario and supercedes previous MDI releases. Originally compiled in the early 1970s by the Resident Geologist Program (RGP), the database is continually being reviewed and updated by RGP staff. In this version of the database, approximately 2700 of the total 19 300 records have been updated or added since the last release (MDI2-October 2002).
Each MDI record provides information on deposit name(s), location, status (e.g., occurrence, prospect, producer, past producer), commodities, character/classification, geological structure, lithology, minerals and mineral alteration, geochemistry, exploration history, and production and reserve data where available. Also included are notes on deposit visits and reference information to more detailed descriptions.
MDI2 data are provided in 2 formats in this release: 1) a relational database, and 2) seamless provincial coverage in geospatial GIS format. The complete MDI2 relational database is provided in Microsoft® Access 97 format. For the geospatial data, basic mineral deposit information (commodities, names, property access) was selectively extracted from the relational database and associated with point locations for each record. Geospatial data are provided in NAD27 geographic coordinate systems in ESRI® shape file format compiled in ArcView® 3.2. ArcExplorer® software has been provided to view and query the shape files.
The database is available on 1 CD-ROM. Price $20.00.
Metadata is "information about the dataset". It tells you about our data so that you may decide on its suitability for your purpose. Review the MDI Metadata.
