Location: This placer mine is at an elevation of approximately 2,200 feet in the headwaters of Montana Creek, 1 mile east of the divide between Windfall Creek and Montana Creek. It is in the NE1/4 section 27, T. 39 S., R. 65 E. of the Copper River Meridian. The location is accurate within 1/4 mile.
Geology: The upper Montana Creek placer deposit was discovered in 1882, shortly after discoveries in lower Montana Creek (JU110)(Redman and others, 1989). There is some production of gold reported but the amount is not documented. Placer tailings, water ditches, and remains of sluice boxes and an arrastre are visible. The mine area is underlain by black phyllite, greenschist, and greenstone. Quartz stringers containing arsenopyrite, pyrite and chalcopyrite occur in bedrock underlying the stream gravels (Redman and others, 1989).
Workings: The upper Montana Creek placer deposit was discovered in 1882 shortly after discoveries in lower Montana Creek. Placer tailings, water ditches, and remains of sluice boxes and an arrastre are still visible.
