Gold was first discovered in Montana in 1852, but mining did not begin until 1862, when gold placers were discovered at Bannack, Montana in 1862. The resulting gold rush resulted in more placer discoveries, including those at Virginia City in 1863, and at Helena and Butte in 1864. [32] In 1867, the Atlantic Cable Quartz Lode was located.

Gold was discovered in placer deposits in the district in 1901. About 350,000 ounces of placer gold have been won from the area, perhaps 85% of it from near Wiseman. Mining continues today in the district. Much of the district is underlain by bedded Paleozoic rocks, a schist belt extends along the southern foothills of the Brooks Range.
Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto western North America to build California lay at the bottom of a large sea. Subsea volcanoes deposited lava and minerals (including gold) onto the sea floor; sometimes enough that islands were created. [1]
