Getting Mining Data for Montana

Portal	Formats	Notes
BLM MLRS (Mineral & Land Records System)	MLRS reports + map viewer (claims by legal description)	Montana BLM claims use UTM Zone 12N for western Montana and Zone 13N for eastern properties. The dividing line is approximately 108°W longitude. Confirm your property's zone before converting to WGS84 to avoid east-west coordinate offset errors that appear as a systematic shift on the basemap.

Mineral claims styled on a map in Exploration Maps.

Tip for Montana: The Stillwater Complex trends roughly east-west for 50 km — a standard landscape (16:9) frame works well for the complex, but a portrait orientation may show the full Complex better. Use the Topographic basemap to show the Beartooth Range backdrop that characterises this world-class PGE camp.
