A thick seam of foliated platy Covellite with the typical blue-purple iridescence containing about 66% Copper making it one of the chief economic ores of Copper.
Discovered in 1877, the Butte district was one of the most important mining districts in the USA. Butte has produced millions of tons of Copper and considerable amounts of Silver Gold, Lead and Zinc as well as some incredibly and highly collectible mineral specimens. During its hey day, Butte was considered the "richest hill on earth". The mineral deposits of Butte fueled the ever increasing demands of our industrial machine and in the process helped build the country to what it is today. Unfortunately, the consequence of these societal demands of the past are the environmental issues inherited today.
