This is a large chunk of copper and tin ore. An old sheet of manilla paper gives the details of mine level and chemistry. Please see the Prov tab for a look at that. The specimen is heavy and contains the characteristic color of pinkish bronze of Colusite. It's definitely a historic specimen since the area in no longer mined and shows good provenance. It's not visually appealing but it represents a rare tin mineral first found at Butte (type locality).

Cu 48.67%
As 9.18
Sn 6.45
