Reopening data is not currently available on the GeoAtlas (https://mars.isc.ca/MARSWeb/default.aspx). Please use only the MARS website for reopening lands data at this time.
The next reopening of lapsed mineral lands has been scheduled for Tuesday, April 28, 2026, at 10:00 AM CST. Clients may log into MARS prior to the reopening time and select lands for a mineral claim application. However, validation and submission of the application cannot proceed until reopening time. Clients should not access the “Acquire a New Disposition” page until about 5 minutes prior to the reopening in order to prevent timeout issues.
