Mining Lands Administration

The ministry acknowledges that the COVID-19 outbreak and related public health requirements are special circumstances that have created challenges for all claim holders in Ontario. As a result, we are leveraging the tools available under the Mining Act to provide claim holders with relief through simplified exclusion orders.

Claim holders with claim anniversary dates on or before December 31, 2020, will be given an exclusion order by making a brief request via email. There will be no cost for COVID-19 related exclusion requests. The exclusion orders will remove the requirement to carry out assessment work for a period of time of up to 12 months.

To obtain an exclusion order, claim holders or their authorized agents must email the Provincial Recording Office at pro.ndm@ontario.ca no earlier than the 30th day before the anniversary date of your claim and no later than 4:30 PM Eastern time on the anniversary date. For more information, please see this bulletin.

Overview

Ontario’s mining lands are registered and managed online with the Mining Lands Administration System (MLAS). With MLAS you can:

  • view active unpatented mining claims
  • register a new mining claim
  • manage your mining claims
  • buy or renew your prospector’s licence

Anyone can use the MLAS Map Viewer to view active, unpatented mining claims in Ontario. However, if you want to register a new mining claim or manage a mining claim, you must register for an MLAS user account and hold a valid prospector’s licence.
