The smithsonite deposit was discovered in 1900. Mining occurred in 1901 and 1902 in what turned out to be a very shallow deposit. The mine consists of two open cuts. The northern cut is 400 feet long and 37 feet deep. The southern cut is only 140 feet long.
Smithsonite replaced the Ste. Genevieve limestone in the form of bedding replacement. Hydrozincite occurred in small amounts and was mined with the smithsonite.
The northern cut is bissected by a mica peridotite (lamprophyre) alnoite dike. Highly weathered, it is still visible today.
Today the cut resembles a large sink hole. Large trees at least 90 years old occur through the mined area. Mineral collecting is sparse, best in the areas where ore was loaded onto wagons and hauled away.
