Tennantite

The Julcani District began mining around 1936 and became the largest producer of Silver and Bismuth. The mine is known for Tennantite after Enargite specimens but Tennantite specimens were not usually collector quality and, thus, there are not many good examples in the market. Ex Mike Wortham
