Regions showing the extent of Mining Licences currently lodged with Earth Resources Regulations. The boundaries are derived from a combination of entering graticular boundaries (exact AMG co-ordinates) and digitizing along areas of land status (Earth Resources version of landmmt100) which are unable to be mined or explored. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) 1990 for more detail. (MIN is included in ML) NOTE: For GeoVic, "Operating Gold Mines" are a subset of this dataset where during the current financial year the tenement recorded production in excess of 100 kg Au, and/or are currently at an advanced stage of resource development with a target production rate of at least 100kg Au per year.

This data represents the Ministry of Natural Resources (MNR) administrative boundaries from 1997-2022. Ministry of Natural Resources (MNR) administrative areas divide Ontario into smaller organizational units. These units were used to manage ministry programs and resources at a district and regional level. Regional and district boundaries were originally created based on: * metes and bounds * topographic features * geographic townships boundaries * territorial district boundaries We made changes to district boundaries over time. We are no longer updating this data. It is best suited for historical research and analysis. __MNR regions__ MNR regions were created to help manage ministry programs and resources at a regional level. Regions consist of several districts. __MNR districts__ MNR regions were divided into smaller organizational units called districts. __MNR areas__ MNR districts were further divided into areas.
