The Delaware Copper Mine was mined for forty years in the mid 19th century. During this period about 3,600 tons of copper were removed from five shafts. The mine had 10 levels, the deepest one being 430 m deep. It was one of the first mines in the area, operated mainly by miners from Cornwall in England. They introduced their mining technology and the famous Cornish pasty to this area.

In 1843 a first mining boom started in Delaware, which is today much less known than the famous gold rush of 1849, but the mining here provided far higher profits.

The mine tour shows the uppermost level at a depth of 35 m. The underground tour is self-guided, it starts with a short video and there are explanatory signs along the trail. The paths are safe and well lit, but visitors get helmets, probably just to create the right atmosphere. If there are questions which are not answered by the signs, they can be addressed at the gift shop after the visit.
