Centennial Mill

The Centennial Mill was actually not built by the Centennial Mine. The facility was instead built by the Arcadian Copper Company around 1900 in preparation for the mine’s anticipated copper windfall – a windfall that never materialized. Besides the mill the ill-fated mine had also erected for itself one of the region’s most impressive surface plants that included modern steel rock-houses, massive stone hoist buildings, as well as a sprawling collection of support buildings and utility infrastructure. Unfortunately the mine managers had forgotten to actually make sure their mine had copper, which it didn’t. Within only a few years the entire operation was scrapped, and the mine’s impressive array of support structures were sold off – including its mill at Grosse Point. Luckily the Centennial Mine was in the market for just such a item and bought the old mill for its own use.
