Ahmeek, Keweenaw Co., Michigan, USA
Miniature, 4.1 x 2.5 x 2.4 cm
Mohawkite, a rare compound of silver, copper, arsenic, cobalt, nickel and iron, is found only one place in the world - in the Mohawk-Ahmeek area of Keweenaw County in Michigan (making this obviously the type locality). This 3.2-ounce nugget has been polished to show its pretty silvery tone with a hint of gold. We recently acquired the only available stash we know about of this material, which was mined in the 1950s. It had been sitting in a garage for a long, long time.
