Key minerals: gold, copper, zinc, silver, coal, platinum. Notable deposits: Pebble, Fort Knox, Donlin Gold, Greens Creek, Red Dog. Mining districts: Fairbanks, Juneau, Nome, Seward Peninsula.

The Alaska Department of Natural Resources administers mineral rights in Alaska. Claim data is accessible through Alaska DNR Online Mapping.

Getting Mining Data for Alaska

Portal	Formats	Notes
Alaska DNR Online Mapping	Shapefile, KML	Alaska DNR uses NAD83 geographic coordinates. The Mining Claims portal allows polygon export by claim group. Alaska spans UTM Zones 5–9 — ensure all boundary layers use the same coordinate reference system before merging, as zone mismatches cause significant positional errors across the state's vast extent.

Mineral claims styled on a map in Exploration Maps.

Tip for Alaska: Large Alaska deposits like Donlin Gold and Pebble span many tens of square kilometres — zoom out to show the full project outline and use a regional inset showing the nearest hub community (Bethel, Fairbanks) and access route to communicate the remote, fly-in logistics immediately.
