Aggregate Resources and Industrial Minerals

Aggregate Resources of Ontario ARO—2020
The Ontario Geological Survey (OGS) is releasing a GIS-based compilation of the aggregate resources of Ontario. This compilation is based on data compiled from aggregate resources inventory mapping conducted by the OGS from 1980 to 2020. It is intended that this compilation will be updated annually. This compilation includes data updated from the previously published information and may include newer geological data and/or mapping, where the latter are available.

It is important to note that this compilation is not intended to be used as a standalone product and the referenced original reports should always be consulted in conjunction with this compilation. Information contained within the referenced original reports (i.e., test results, resource properties and potential) is still highly relevant. However, it is possible that resource estimates provided in the referenced original reports may no longer be accurate, and may not reflect the data contained in this compilation. It must also be noted that, although the data represented in this compilation have been modified and updated since the release of the previously published information, the referenced original publications have not been revised to incorporate these changes.

The Aggregate Resources of Ontario—2020 (or ARO—2020) is available as a direct download from OGSEarth (www.ontario.ca/ogsearth). The compressed (.zip) download file provides ARO—2020 data in geodatabase format using ESRI® ArcGIS® 9.3.1 with a completed project file (.mxd). Geospatial data are provided in North American Datum 1983 (NAD83) geographic co-ordinate system using decimal degrees. A user document and readme file that explains the GIS content is provided.
