Abandoned Mines and Hazards Databases and Reports

The following databases and reports are used by staff to monitor and catalogue the more than 5,600 abandoned and inactive mine sites and mine hazards within the province:

AMIS (Abandoned Mines Information System)

• AMIS is a database containing basic information on all known abandoned and inactive mine sites located on both Crown and privately held lands within the province of Ontario.
• Information stored on each mine site can include site name, alternate names, location, period that the site was active, tenure, all mine features known to be located on the site, known hazards and their level of protection, inspections, remedial action taken and a selection of references.
• Public access to some of the information stored must be restricted under various sections of the Freedom of Information and Protection of Privacy Act (FIPPA) unless consent for third party access is given by the person or organization(s) to whom the information relates.

Site Assessment Reports

• Site Assessment Reports have been prepared by various consultants on abandoned and inactive mine sites within all of the Resident Geologists' districts in Ontario with the $6 million in costs obtained from both government rehabilitation programs.
• Provide information on the location, access and ownership of each mine site, as well as a description and, where applicable, an estimate of both the short and long term measures and costs required to rehabilitate all mine hazards found on the site.

Geotechnical Investigation Reports

• Geotechnical Investigation Reports contain information regarding geotechnical investigations of abandoned and inactive mine sites within various municipalities and other locations throughout Ontario.
• Contain information such as surface crown pillar stability analyses, monitoring methods, recommendations for remedial work and recommendations of zones of caution for municipal planning.

Mine Plans and Sections

• These are various mine plans (both surface and underground) and sections submitted by mining companies and stored by MNDM.
• Microfiche copies of these plans and sections are available at the Abandoned Mines Office in Sudbury and paper copies are available at most of the appropriate Resident Geologists' Offices throughout the province.
