Check out the new Mining Assessment Report layer in Skyline!

The Yukon Mining Assessment Report Footprints database contains over 7,500 reports documenting mineral exploration activity in Yukon since the 1950s. The majority of these records are open to the public, more recent reports are confidential (see above). Each geometric shape on the map represents a report on the work performed in that area. Key information about these reports has been captured, such as report number, title, author, year, claims, property name, expenditures, and a link to the scanned report.

To access this map layer through Skyline, uncheck the ‘Airphoto Library’ layer on the left side menu, and check the ‘Geology’ layer. Click the plus sign beside ‘Geology’ and check the box for ‘Assessment Report Footprint’.

Or check out the stand-alone version - same information, but without the other map layers.
