|
Native copper in its pure metal form is the most sought after mineral of this fantastically mineral-rich peninsula. Varying quantities can be found in the waste rock piles of the historic mines. It is also found in a variety of soils and gravels which contain copper that was deposited by glacial movements. Rare silver specimens can sometimes be found. Metal detectors are very helpful, but not necessary, to find metallic prizes.Some of the more popular collecting sites include the old Mandan, Delaware, Central and Phoenix mine sites along US-41 in Keweenaw County and the old Cliff Mine site along Cliff Drive. Houghton County's Baltic area may also be a place to visit. The piles of waste, or "poor rock", near these sites may sometimes yield overlooked pieces of quartz, datolite or mohawkite.
Remember, the areas you're searching may be someone's back yard ...please respect private property, use common sense, watch for signs and don't litter.
