This small specimen actually consists of both Native Copper and native silver, which sometimes associate with each other on pieces from this locality. The copper occurs both in a sheet form and as a thick, flattened wire which holds a small sheet to another sheet. The copper has a dull, coppery-red color and a dull metallic luster due to some slight oxidization, and appears to show some subtle signs of crystal form. The silver is attached to the ends of the copper sheets, and appears to continue on where the Copper left off in a similar form, but not showing as many crystalline tendencies. It has the standard bright, silvery color and a slightly higher luster in some areas. There are a few small bits of a black matrix rock stuck to the formation, one of which contains a tiny, transparent calcite crystal.
