CLAIMaps displays the location of land where claim staking can or cannot occur.
In addition to active and pending mining claims, CLAIMaps also displays the following data:
- Active and pending dispositions
- Pending withdrawals and notifications
- Administrative boundaries
- Base data
CLAIMaps polygon data can be analyzed and combined with other data through the use of desktop geographic information system (GIS) software. Data is available in ESRI® ArcView® shape file format.
Mining claim maps can be purchased in paper format from the Marketing Services Publication Sales Coordinator. Maps are available at two standard scales: 1:20000 and 1:40000. Pricing varies depending on desired size and colour quality.
Historical Mining Claim Maps
Before the creation of CLAIMaps, mining claims had to be drawn, by hand, on a map made of paper, linen or Mylar. These mining claim maps are now known as historical mining claim maps. All historical mining claim maps have been digitized and are now available in electronic Portable Document Format (PDF) from the Historical Mining Claim Map website.
Withdrawals and Reopenings
The Ministry may change the status of a parcel of land to remove it from staking or to enable it to be staked. These actions are known as withdrawals and reopenings respectively.
To view a listing of withdrawals and reopenings visit the withdrawal and reopenings website.
June 1st Open List
Each year the Ministry publishes a list of lands and/or mining rights open for staking on June 1st. This list is published in one issue of the Ontario Gazette and may also be viewed by at this location. Please note that some of these lands may be subject withdrawal under the Mining Act and you are encouraged to reference mining claim maps and/or contact the Provincial Recording Office if you have any questions. Also note that some of the lands on the list may have mine hazards within their boundaries. Please conduct your mineral exploration activities accordingly.
